Hi all. I recently upgraded and was having a heck of a time trying to find out how to install java6 on the new Mint 13 since they pulled all the PPA's due to licensing restrictions. These are the steps I took to get it installed and working with Mint 13 Maya. This SHOULD work for other flavors of Precise.
Open terminal and in it type:
Code:
sudo apt-get purge openjdk*
ENTER
Code:
sudo apt-get purge *jre*
ENTER
Open up synaptics package manager and do a search for JRE or any other java related packages, make sure they are uninstalled.
NOW.
Once you are sure you've cleansed your system of any other java muck that might conflict you need to download this script.
https://github.com/flexiondotorg/oab-java6/blob/master/oab-java6.sh
Alternatively, open up a plain txt file and copy this code into it. The download link will more than likely be more up to date, but i'm putting this here for shiggles. Name it whatever you want.

Whether you download the script, or if you make your own text file, you need to enable the executing permission bit. So change your directory to wherever you saved the script and then in terminal type this and hit enter:
Code:
chmod +x ./whatever_the_script_is_named
Then in the terminal run the script with:
Code:
sudo ./oab-java6.sh
or
Code:
sudo ./whatever_you_named_this_script
What this does, is build packages for your system and places them in a local repository for apt-get to install. This bypasses java anal retentive licensing bullsquash. So, now we need to install it with:
Code:
sudo apt-get install sun-java6-jre
ENTER
Wait for it to finish and ensure your version is correcty by typing:
Code:
java -version
ENTER
You should get an output similar to:
Code:
[email protected] ~ $ java -version
java version "1.6.0_32"
Java(TM) SE Runtime Environment (build 1.6.0_32-b05)
Java HotSpot(TM) 64-Bit Server VM (build 20.7-b02, mixed mode)
[email protected] ~ $
Hope this helps someone and I hope this is in the correct forum!
Im going to be editing this as it seems there's really no reason to purge OpenJDK from the system, I think. I'm also having some compiling errors so once I get those nailed down, I'll probably just write a guide detailing the entire setup/config for 12.04.
It works !!!
Thanks for posting this, this worked well.
Only thing I would like to add is that if someone is looking to add the java plugin to firefox, then they would need to manually create a link in the firefox plugins directory:
$ cd /usr/lib/firefox-addons/plugins
$ sudo ln -s /usr/lib/jvm/java-6-sun-1.6.0.32/jre/lib/i386/libnpjp2.so
$ ls -lrt
total 0
lrwxrwxrwx 1 root root 57 2011-12-20 11:05 libnpjp2.so -> /usr/lib/jvm/java-6-sun-1.6.0.26/jre/lib/i386/libnpjp2.so
Restart firefox, it should work now.
Keep It All!
Hi folks
I'll just chuck an alternative method in for good measure and one that I successfully on ubuntu versions 11.10 , 12.04 and 12.10 as well every other debian derivative
Add these three repositories like so.
Code:
sudo add-apt-repository "deb http://archive.ubuntu.com/ubuntu hardy main multiverse"
sudo add-apt-repository "deb http://archive.ubuntu.com/ubuntu hardy-updates main multiverse"
sudo add-apt-repository "deb http://archive.canonical.com/ lucid partner"
sudo apt-get update
You can then install both version 5 and 6 of the sun jdk and leave any existing installs in tact.
For extra beans you can install openjdk-7-jdk without any adverse effects - I ran the following
Code:
sudo apt-get install sun-java6-jdk
sudo apt-get install sun-java5-jdk
sudo apt-get install openjdk-7-jdk
After that you can use /bin/update-aleternatives to manage which version to use. for example
Code:
sudo update-alternatives --config java
This gives me the following versions of java to use as my "java" command
Code:
There are 4 choices for the alternative java (providing /usr/bin/java).
Selection Path Priority Status
------------------------------------------------------------
0 /usr/lib/jvm/java-6-openjdk-amd64/jre/bin/java 1061 auto mode

3 /usr/lib/jvm/java-6-sun/jre/bin/java 63 manual mode
* 4 /usr/lib/jvm/java-7-openjdk-amd64/jre/bin/java 1051 manual mode
Press enter to keep the current choice[*], or type selection number:
Pick which version you need/want to use and away you go, you can switch most of the applications on the java platform painlessy with this method this includes javaws, javah , javac , jdb. if you're working with android only javac and java is required however, so do the same for javac
Code:
sudo update-alternatives --config javac
see "/etc/alternatives" for a list of application which may have alternatives and obviously the man and help has full details and how you can manage applications I also think there is a Kde, Gnome front end for it as well.
I got the repo info for sun jdk 5/6 from google's Android AOSP build instructions

thank you!
Thank you! I've tried many other scripts and sites without success. I should have started with xda for this. Thank you again.
Script location update.
Just an FYI, the location of the script has change, as the author has also included it to install Java 7.
The new location is https github.com/flexiondotorg/oab-java6
NOTE: the script pasted in the OP no longer works as making the .deb file will fail unless you download the jce_poclicy-6.zip. (which the script deletes the next time you run it)
EDIT: I also tested this on Ubuntu 10.04, and it is working for both JRE and JDK
Can you confirm whether this method still works? I have followed the directions here and on the source.android.com website to install sun-java6-sdk and my ubuntu 12.04 is not finding the install package. When I run the update script the hardy repository is giving me 404 errors. Have things changed significantly since this was posted?

Hi There,
Yes I believe they have as I noticed the same thing just recently, Although I will be looking a bit deeper when I installl 13.10. You are better off using the webupd8 team oracle java installer now I think, additionally AOSP master branch doesn't build anymore with the sun java version.

Yes I believe they have as I noticed the same thing just recently, Although I will be looking a bit deeper when I installl 13.10. You are better off using the webupd8 team oracle java installer now I think, additionally AOSP master branch doesn't build anymore with the sun java version.

which java version is worth using then? Openjdk v6, 7 or 8? I am considering trying to build CM 10.2 and I see they recommend to use Openjdk. Any thoughts?

I haven't use the openJDK offerings so I couldn't recommend one, I'm afraid. However, I did a little moreresearch google search into Hardy's disappearance. it turns out Hardy Heron 8.04 was EOL'd in May [ Announcement on the Ubuntu Fridge ]
All is not lost though as the hardy repos have just been moved to http://old-releases.ubuntu.com/ .
so if If you really need the sun java6 jdk or even sun's java5 jdk you can add these lines to you /etc/apt/sources.list and they should install fine.
Code:
deb http://archive.canonical.com/ lucid partner
deb http://old-releases.ubuntu.com/ubuntu hardy-updates main multiverse
deb http://old-releases.ubuntu.com/ubuntu hardy main multiverse
However as previously mentioned the sun java6 jdk no longer builds the master branch of the AOSP but at least the correct links are there for future reference. Currently Webupd8 team have the latest (now) oracle's version of the java6 jdk which is what I currently use for building. So to install oracle's versions of the jdk, do the following
Code:
sudo add-apt-repository --yes ppa:webupd8team/java
sudo apt-get install oracle-java8-installer
sudo apt-get install oracle-java7-installer
sudo apt-get install oracle-java6-installer
Obviously you can use update-alternatives to switch between them as/if required and make's the question of which is worth using/installing kinda moot ... Install them ALL! I haz every java. lol
Thanks

Updated 03.26.14 - Released v2.1 - bug fixes and code cleaned
Introduction:
I am by no means a developer. I am just an android enthusiast who has learned a bit of bash. The reason I made this script was that settings>>wifi>>advanced was not promptly turning wifi off when my device would sleep; sometimes it would not turn off at all. So I figured since I am making a script to resolve this issue I might as well add a couple of other functions as well. To this end I noticed some people saying THIS APP was helpful and I missed the Flush-O-Matic script from V6 SuperCharger so I added fstrim and drop_caches=3 to the script.

What will this do?
The script will allow you to sync wifi, fstrim, and/or drop_caches=3 with sleep and/or it will allow you to schedule fstrim and/or drop_caches=3 using crond. The scheduling option can work on either a hourly (you can choose to run desired programs every hour on the hour, every two hours on the hour, every 3 hours on the hour, etc) or daily basis (you can choose to run desired programs at a given time on the hour).
Both the sync and schedule options will load themselves in to memory each boot and each time your device goes to sleep and/or when scheduled the scripts will depending on your options: (1) sync your data so as to ensure no data is lost; (2) TRIM your /system, /data, and /cache partitions; (3) DROP CACHES = 3; and (4) turn off wifi.
In addition, there is also an on-the-fly script to manually trim partitions and drop caches when desired.

Benefits:
Reduce lag/improve i/o efficiency (see THIS and THIS).
Although android automatically invokes fstrim when certain conditions are met, these criteria could seldom if ever be met depending upon your usage style. The init.d script should ensure fstrim is invoked more frequently for most users.
Should use less ram than apps that perform similar functions (I say should because I have never used such apps, but I imagine they consume more that .2-.5 mb of ram).

Warning/Disclaimer:
Although these scripts function as intended on my device – Nexus 7 (2013), SlimKat (weekly), ElementalX...Use at your own risk. Neither I nor XDA are responsible for any possible deleterious effects.

Known Issues/Bugs:
If you use the sync option, scripts with a lower priority than Z99 will not execute.
The log files don't always display as intended...dunno why...any help/suggestions would be appreciated.
Let me know if you find any others .

Install, Usage/Verification, & Uninstall:
Install -
Note: If you use crond for other tasks, both the install and uninstall routine account for this potential contigency and should leave your other crond tasks uneffects.
make a nandroid backup
download the zip (<<NOT flashable) attached to this post
extract the zip’s contents
if you were/are using the first version of this script manually delete: /etc/init.d/07TrimDropOff, /data/TrimDropOff_Awake.log, and /data/TrimDropOff_Sleep.log
run TrimDropOffInstaller with superuser permission via terminal or script manager.
follow the scripts prompts
reboot
enjoy
Usage/Verification -
Assuming you have followed the install procedure, next, put your device to sleep and then wake it if you are using the sync option.
Now check the various logs in /data/TrimDropOff. The logs will show the time, the script’s PIDs, the path of the PIDs (just to double-check the PIDs are correct), the ram used by the PIDs, action(s) preformed (amount trimmed from each partition and/or if drop_cahes was run), or errors.
If you want verify manually via terminal do [pgrep -f TrimDrop] for the sync option or [pgrep crond] for the scheduling option to get the PIDs, do [cat /proc/PID/cmdline] for each PID to verify it truly belongs to Z99TrimDropOff or crond, and do [dumpsys meminfo | grep PID] for each PID to verify ram usage (this command will yield duplicates, which can be disregarded and may output undesired additional results, which can be filtered by looking through the results for the relevant PID).
To use the on-the-fly script to trim and/or drop as desired, in terminal do [su -c trimdrop].
Should you want to reconfigure your setup, uninstall before reinstalling to avoid potential issues.
Uninstall -
Note: If you use crond for other tasks, both the install and uninstall routine account for this potential contigency and should leave your other crond tasks uneffects.
Rerun TrimDropOffInstaller with superuser permission and use uninstall option at the beginning of the script.
Reboot and all will be back to as it was before.

Changelog:
v2.0
made in to installer script
added cron options
added bootloop precautions to the init.d scripts (should make it compatible with all devices that meet the requirments)
the on-the-fly script, trimdrop, now allows user to choose fstrim and/or drop_caches=3
added more syncs to further ensure no data is lost
a bunch of other stuff I probably forget
v2.1
bug fixes - fixed issue if using only sync option (missing directory); fixed display of irrelevant errors in uninstall routine
cleaned code a bit (reduced redundancy)

Big thanks to @zeppelinrox, @dk_zero-cool, & @gu5t3r for their contributions to portions of this script (see the code of my other script SwapItOn for detailed citations).
Much thanks to @mdamaged for spotting the issue with sync init.d script and his note regarding syncing data.

Don't forget to click THANKS and RATE 5 STARS if you found this useful :highfive:.
peep my other script SwapItOn
Update to v2.1 if you were only using the sync option.
If you were using both the sync and schedule options or only the schedule option there is no need to update; the bug I found would not effect you.
reserved...on the off chance it will be needed
Thanks, sounds interesting. I'm assuming the zip can be flashed right after flashing a new rom?

Is compatible with custom kernel? Franco in my case

Will performing trimming operations too frequently cause additional flash memory degradation?

As you were informed the zip is NOT flashable. If there is sufficient interest (say a 100 downloads) I'll make it flashable/aroma.

Yes, it should be compatible...the fstrim utility is part of the rom (it should be in all nexus 4.3+ roms).
creeve4 said:

No, to my limited knowledge it should not be harmful (in fact it should increase lifespan - google "fstrim lifespan"). Did a quick google search but could not find anything definitive/reliable regarding frequency...what I did see seemed to suggest 'no' though.
If you are concerned about the frequency, you could not install the init.d script and just use the on-the-fly script, trimdrop, to trim on-demand. Should there be interest and if I have the motivation and time, I have been thinking about making this in to an installer script and/or aroma zip with cron-based options so it could be scheduled hourly, daily, or weekly.
Scheduling options would be awesome!

Seems there is a decent amount of interest (almost 100 downloads already ...thanks peeps), as such I'll add options and make things more configurable.
Regarding scheduling, I was thinking of doing hourly, daily (with ability to choose time), and weekly (with ability to choose day and time) options. Would every other hour or some other setting be desirable?
Regarding installation, what would be the preferred method, an installer script (e.g. V6 SuperCharger) or AROMA? Flashable zips would be another option, but would have less options/be less configurable.
Gimme some feedback and I'll put something together in the next week or two depending on work and my motivation .
wasn't this a nexus 7 2012 issue and fixed in the new version 2013?

My 2 cents:
I would choose a daily option for my device.
I prefer Aroma over a script, but if you cannot get the customization you want with Aroma, then by all means go with a script.
Thanks again for the script and willingness to make it even better!
Thanks for the scripts, I time my startup, and this improved startup time by about 3-4secs, among other noticible improvements, apparently the stock OS does not run fstrim enough, initial operations freed several gigs on the data partition, and hundreds of megs on the others...

Im going to turn this into a cron job, that will take care of scheduling, unless anyone else gets there first ( please lol )
Will give it a go in its present form, whats its resource footprint just sitting there waiting for screen off ?
Can we trigger the action from the screen off event ? or some other interupt type way ?
Great script by the way, your bash is damn site better than mine, jealous lol

Yes, I think this is true to a degree...it was more of a problem on the 2012 and other nexus devices. See the links in the OP for the conditions that need to be met for fstrim to autorun...for some users (myself included) the conditions will seldom if ever be met. Also see @mdamaged post; I get similar results the first time fstrim is initiated by my script after each boot...subsequent runs normally only frees up memory on /data.

See the first post on this page and my response to @creeve4 and @imfun in this post. I will make an AROMA package with cron options for fstrim and drop_caches=3.
However, should you feel ambitious and beat me to it, props to you...I will give you full credit in the OP and link your post as the d/l source so you should get the 'thanks' too.
Regarding triggering with screen on/off or some other event: It can probably be done, but I it's beyond my knowledge (screen on/off was actually the first trigger event I looked in to using, but despite fairly extensive searching I could not find how to detect it).
Regarding resource footprint: Read the OP (usage section) it explains where to find the log which contains this info and how to do it via terminal (should you not trust me )...also see OP (benefits section): in all my testing I have never seen it use more that .8 mb, but most of the time it is less than .2 mb.
Okay will get to making an AROMA package...it will be my first, but it looks easy enough :fingers-crossed:...gimme a week or two to put it together and fully test.

Can't wait already, because after whole day or two, hard usage of my nexus 7 tablet, the tablet starts to get laggy. I can see this on web browsing, touch press delay time, and onyl rebooting seems to help... Hope after istaling this will solve the problems
ohhh no dont want any credit lol lol, i have turned it into a cron job quite simply by adding it to the cron initilising script

For an aroma script you will prob have to stick the file in /system/etc/cron/cron.hourly, daily, weekly and just give peeps that choice, will be most simple way. Ps not a fan of aroma lol
Ok, I should have spotted this issue right away, but did not, so here goes. It seems the use of while loop in the script in the OP causes any scripts with a lower priority in init.d to never get ran, if the script in the OP is the only one in your init.d this does not matter, nor should it matter if you have at boot script with a higher priority (they get ran before the OPs script).
I run the ElementalX kernel which depends on a init.d to initialize some parameters for the kernel, with this script in init.d they never get initialized, in my case this resulted in some things not 'taking' such as the battery life extender, which on my device, is set to stop charging at 4100mv, however, since the while loop kept the ElementalX init.d from running, it kept charging to ~4300mv, this is how I noticed (actually none of my settings wrt ElementalX were being initialized, but this symptom was most pronounced).
A simple fix would be to move up the priority of the ElementalX init.d script, but this would have to be done after each flash, and frankly since I run Tasker anyway, I saw no need for this, what I did was remove the OPs script from init.d and simply made a very simple task in Tasker to run /system/xbin/trimdrop when display goes off, it could just as easily be a time event.
Anyways, hope that helps someone who may come across this with other kernels, or other at-boot scripts which depend on being ran before the OPs script.
Again, thanks to the OP for his work. Also, I added another sync just before the drop caches, since the state of dirtyness could change after the fstrims.

Read the entire thread, this is a community! we should help each other instead of acting high and mighty because you know a lot of things and you thought you knew most of the things. If you see some bugs and notice some errors why not try to help and give solutions to OP other than ranting, you knew a lot of things right? such a waste knowledge. After all, scripts and tweaks we're not made by a single person, made by exchanging ideas,self efforts and the efforts of the community.

Hi,
you have terrible mistake in your script:
file: 88Dash_Engine:
line: 208
Line not ended with ". Your script will not work and give errors.
This:
is not necesarry to do:
start at:
$( date +"%m-%d-%Y %H:%M:%S" )
==========================" | tee -a $LOG_FILE;
start at:?
You should just log command outputs to LOG_FILE ... not entire script.
And as always:
this code:
Code:
tune2fs -o journal_data_writeback /block/path/to/system;
tune2fs -O ^has_journal /block/path/to/system;
tune2fs -o journal_data_writeback /block/path/to/cache;
tune2fs -O ^has_journal /block/path/to/cache;
tune2fs -o journal_data_writeback /block/path/to/data;
tune2fs -O ^has_journal /block/path/to/data;
will never work.
^^^^ This ^^^^
We are here to further development. Keep the critical comments and insults out of here.
Be nice, work together to sort out issues, and try to get along for the good of all. Moderators do not ban those who are be respectful and trying to learn.
Final warning in here, be nice or get out.

Just to add, could somebody please tell me what this does?
Code:
##Syctl-Launcher
# grep sysctl /etc/init.d/*
/etc/init.d/02vm:# Load /sys/etc/sysctl.conf
/etc/init.d/02vm:sysctl -p
Because there is no 02vm script in init.d and these two lines doesn't seem to make sense to me.

I just pointed not working commands. Thats all.
I asure you (all of you) that those commands about tune2fs are copy&pasted from other so called "performance" mods.
Everyone is just copying same mistakes here on XDA, and none from so called "devs" actually are testing their mods.
You don't have to be a developer or programmer to see that this:
Code:
tune2fs -o journal_data_writeback /block/path/to/system

A whole debugging log of your script. As you can see its not finished as it got stuck at line 209.
I am done with this thread. Good bye.

Thanks @eushaun99
This clearly prooved my comment.
@myaservip:
Do you know why this has errors?
Code:
tune2fs: No such file or directory while trying to open /block/path/to/system
Couldn't find valid filesystem superblock.
Also about not working half of the script. As I said you didnt close echo commands by ".
pivotce.com informs that instructions have been published on gaining root access to a webOS TV. This is much harder than on the old phones and tablets. When this was done on legacy webOS, there was a wave of enhancements and tweaks made available to phone users from webOS Internals and other developers.
The instructions can be found on the Russian webOS forums here: webos-forums.ru/topic4650.html (English Translation via Google).
As the thread itself notes, this creates the possibility of fiddling with your TV in a way that may turn it into a large, thin brick and will almost certainly invalidate your warranty. The general user should stay well clear of this.
pivotCE published this for information only and recommend leaving investigations to those who know what they are doing or who can afford to wreck expensive television sets. We will watch to see if anything interesting emerges from this development.

Detailed analysis of the root access method described above:
forums.webosnation.com/lg-webos-tv/331754-pivotce-seems-webos-tv-has-been-rooted.html#post3450911
Hello!
I'm from webos-forums.ru. I've root on TV for a while and can help you with translation or testing on LG webOS 1.4.

I could use your help rooting my lg 65uf6450-ua if you would. Thank you

1. You need to install Developer Mode App and export private ssh-key with CLI (webostv.developer.lge.com/develop/app-test)
2. Convert private ssh-key with puttygen [import key <your private ssh-key>, then save private key]
3. Download exploit (zalil.su/6937580), then connect with TV User: prisoner, [<ip-tv>:9922] + private-key with WinSCP (or other SCP-client), upload to /media/developer on TV and rename it to root.
on linux
Code:
ssh -i <your private ssh-key> [email protected]<ip-tv> -p 9922 "/bin/sh -i"
4.
Code:
chmod +x root
Code:
./root
5. After try install any app from market go to LG App Store and try to install any app.
6. if third stage ok. the insert password 1111 as said.
7.
Code:
busybox chroot /proc/1/root
Code:
[email protected]tTV:/# id
Code:
uid=0(root) gid=0(root)........
I personally use Linux Subsystem on Windows 10 for all of this.
To install .ipk app:
Code:
ApplicationInstallerUtility -c install -p /tmp/<any-name>.ipk -u 0 -l /media/developer -d
Info about your linux kernel and TV firmware:
Code:
luna-send -n 1 -f luna://com.palm.systemservice/osInfo/query '{ "subscribe": false }'
Launch app:
Code:
luna-send -n 1 -f luna://com.webos.applicationManager/launch '{"id": "netflix"}'
All apps ID you can find with
Code:
luna-send -n 1 "palm://com.palm.applicationManager/listLaunchPoints" "{}"
or at a folder /media/cryptofs/apps/usr/palm/applications/<App ID>/appinfo.json
For permanent root access through telnet:
1)
Code:
[email protected]:/# mkdir -p /media/cryptofs/root/etc
2)
Code:
[email protected]:/# cp -r /etc/* /media/cryptofs/root/etc
3)
Code:
[email protected]:/# mount -o bind /media/cryptofs/root/etc /etc
4)
Code:
[email protected]:/# passwd root
Enter any new root password
5)
Code:
cp /media/cryptofs/apps/usr/palm/services/com.palmdts.devmode.service/start-devmode.sh /tmp/start-devmode.sh
6) Download with WinSCP start-devmode.sh and edit it locally.
You need to add at the beginning
Code:
mount -o bind /media/cryptofs/root/etc /etc
telnetd -l /sbin/sulogin &
Plus you can add the line to launch any App at start, e.g:
Code:
luna-send -n 1 -f luna://com.webos.applicationManager/launch '{"id": "netflix", "params":{}}'
And comment Dev Mode online check.
Here it's mine start-devmode.sh. It's for webOS 1.4. It can be different for other webOS versions:
Code:
#!/bin/sh
mount -o bind /media/cryptofs/root/etc /etc
telnetd -l /sbin/sulogin &
#luna-send -n 1 -f luna://com.webos.applicationManager/launch '{"id": "netflix", "params":{}}'

Hi, would the root access allow somehow to connect other bluetooth devices different than LG? Thanks!
You can do pretty much anything to the system with root, even include support for unsupported devices in form of additional kernel modules.
For example, I've added Samba support so I can mount use my NAS (see my blog at ddscentral dot org for details).

Basically what I want to do is convert this into batch script for windows and by using Linux Binaries from Sourceforge create a script that basically does the same thing except it doesnt have to be pushed into my Phone's system it works directly in windows using ADB commands!
The script in question looks like this
Spoiler: THIS Script
Bash:
#adb shell mkdir /data/media/0/PartitionImages
#adb push .\backupPartitions.sh /data/media/0/PartitionImages/backupPartitions.sh
#adb shell chmod 0755 /data/media/0/PartitionImages/backupPartitions.sh
#adb shell /data/media/0/PartitionImages/backupPartitions.sh
#adb pull /data/media/0/PartitionImages .\PartitionImages

I tried by guidelines from an "Appendix N. Converting DOS Batch Files to Shell Scripts" from another site to turn the shell script variables into batch script ones but since I got no experience with either of them my attempt turned into an amalgamation of the two's code in one..
Spoiler: it turned Into THIS
Code:

::adb push .\backupPartitions.sh /data/media/0/PartitionImages/backupPartitions.sh

additionally I have pretty much all linux commands's binaries on the same folder as the .bat script so as long as the syntax is correct and nothing finniky going on it should work technically but since I got no experience I can't do this on my own...

I have tried that script itself and it failed at "DM-Verity" and SELinux enforcement also for some reason no logs at all in temp folder
