java8 for android? the sollution might be here! - General Topics

Im what you might call a trainee android developer working with java and i might have found a sollution for java8 on android. Well, here i go:
step 1. download jdk-8u66-linux-i586.tar.gz it should be under the linux category
step 2. Extract the tar.gz with the Rar app for android. or use a computer.
step 3. locate the extracted copy of the archive
step 4. go to:
jdk-8u66-linux-i586/jdk1.8.0_66/jre/lib/
step 5. there should be a file names rt.jar
rt.jar includes the entire directory for java8 and all class files. most likely an API
THINGS TO NOTE:
1. if you are developing code on a android and not a computer(like i am) you may see some class files twice in your IDE.
2. to my knowledge, i am not quite sure everything will work the same as if on a linux computer.
thank you for taking your time to read this.
sorry if i post this under wrong category, completely new to forums!

Putting togeter exe from wm6 image (noob)

Hi,
Following this thread: http://forum.xda-developers.com/showthread.php?t=310287 I created a dump directory for a WM6 image. Inside the SYS directories are a number of subdirectories. Some of these subdirectories have familiar names (e.g. calendar.exe). Using calendar.exe as an example, there are 5 files: imageinfo.bin, imageinfo.txt, S000, S001, and S002. Here are my questions:
1. What are these 5 files?
2. What tool would I use to put the folder together to create a single executable?
Sorry for the noob questions but I can't find the answer on the forums!!
OK, after trying out all of the tools in one of the bundles, I found the answer to the second question:
2. Within someone's kitchen tools (I don't remember which one I downloaded) was a file called recmod.exe. Run it with the folder as a parameter and it will put the exe together.
I still don't have the answer as to what those 5 files are though.
My terms may be off base but I'll try to explain what these files are as I understand it (and hopefully not look stupid in the meantime as I'm also trying to explain it in layman's terms).
Many core files are constructed like this so that they are optimized in the Rom to make them run more efficiently on our devices.

[Q] Rar on android.

Hi:
I've recently started to develop my own comic reader. The problem I've come up with is cbr files, which are esentially rar files. Now I know there are comic readers out there (all of them, I think) that support cbr files. So there is a way of doing this, I just can't find how.
In the rarlabs official page (search google rar addons and it's the first page) there are several options. I would like to know if I download the commandline arm unrar how I could install it on Android (I have a motorola Xoom, it would be for Honeycomb), assuming that is correct.
If this is not an option is there a command line unrar application that I could call from my own? and How would the code be (to call an external application, that is)?
If the above is not possible, what is the way to get to unrar something in android?
The only real option I've seen would be to use junrar (hosted on github)
But it seems complicated and I'm not sure it works very well as I've seen a lot of conflicting reports.
Thanks for any help!
Try http://www.all-freeware.com/results/rar/for/android to unpack rar on Android.
Success,
Senax
Hi:
I'm not exactly sure what you wanted me to try. There is nothing in that page that would allow me to uncompress a rar file on android. Only a bunch of unrar utitilities and some android things but they are not related, that is, there is nothing that says unrar that also works on android.
thanks anyway.
Unrar
great app available here: androidzoom (dot) com/android_applications/tools/unrar_dhpu.html

Hi:
It's seems that I didn't make myself clear.
I want to develop an android application that needs to unrar files. Is there a way to call the unrar application from my own code?
If so, can you tell me how?
Otherwise, I appreciate the effort, but I can't use that.
Thank you very much!
You can bring the unrar binary along in the /asset of your app,
on first launch copy it to your apps /file directory, chmod +x it, and use exec("sh") to unrar the files from shell.
oh, I see. I think I get the the idea but I don't understand all the instructions.
What did you mean by importing thebinary on my asset?
If I do the step above why do I need to copy the binary on first launch?
Don't I need root privileges too chmod it? And how do I do it from my source code?
And finally where can I find the command line use of the application? Or is it the same as the Linux version?
I know there are a lot of questions, but please keep in mind that I'm very new at doing this.
Thanks for all the help!
You need to put it as asset to bring it along.
You need to copy it because asset files are not directly accessable.
You don't need root to chmod the file in your own directory.
You do it by using a shell from your code i.e. Process.exec("sh")
And finally you want to program the app not me,
so don't be lazy and invest some time.
Google google google google...
If there are still questions left after that, you may ask again .
Ok, I'll try it and get back to you!
Thanks!
Sorry for my lazyness, but I've been Googling for a good half hour without finding a simple 'unrar' binary executable compiled to run from terminal on rooted ARMx32 device. I don't want bloated GUI APK's or libraries for development implementation, but just the plain command line interface executable. Anyone, please? It's a pity they haven't baked it into Busybox as an applet, IMO.

[how to] Develop on Windows RT: A C# Scratchpad

Steps:
(Yes, you need Jailbreak first.)
Download CsBox.zip from this thread.
Unzip the CsBox folder to your user's folder (in my case it's C:\Users\ssaaxx\Desktop\Scripts\)
Get Notepad++ and run it (from the App porting thread)
In Notepad++, Create and save a C# code snippet (A sample code snippet can be found in TestCSharp.cs.txt attachment)
In Notepad++, click "Run" menu --> "Run..." --> Input following text and run (or you can save it as a command shortcut if you want to)
C:\Users\ssaaxx\Desktop\Scripts\CsBox\RunCsSnippet.bat "$(FULL_CURRENT_PATH)"​
There you go!
* Do use the right folder path for you.
------------------
How does it work?
Windows RT ships with a CSharp compiler (csc.exe), except it's not working by default because of missing some referenced dlls.
So I commented out the missing references from the rsp file, and it worked.
After this it's just some basic scripting and Notepad++ integration.
-----------------
Edit: fixed a bug. thanks Calebsem.
Edit: Hide compiler output when compiling succeeds.
cool!
Very cool little hack! I've been looking forward to a way to program C# on the Surface!
Just to demonstrate what this "scratchpad" is capable of, I'll update this reply with some handy scripts:
1. Script to enable Adobe Flash for specified website / domain: EnableFlash.zip
...
* Download the zip and unzip the cs file. Load it in Notepad++ and run.

Thanks for the cool utility and guide! I was able to work it out to compile a multi-file .NET project. One snag that I hit in the endeavor was about the resources. ResGen.exe does not come on the RT version of Windows. I used my desktop to compile the various resources and then stuff them into the directory tree. At last, the program I re-built was completed and launched well. It consists of an exe and two dll files. All's well for that experiment. Unsure if I can make the time to do a clean room build of ResGen.exe for ARM.
I'm surprised this topic didn't get as many posts as it did. Found this thread through a youtube video, and this has got to be one of the best kept secrets for code development on the RT. A quick replacement of the csc.rsp file after toying with permissions, and adding the csc.exe to my PATH basically allows command-line C# building.
Wondering if the missing DLLs actually appear on different versions of RT. Not that these specific namespaces are something I regularly use, but it would be nice not to have to comment things out this way.

[TOOL][Windows] Windows Shell Extension: Checksum Comparer

Hello I have created a Checksum Comparer Application for Windows. The application is capable of installing a Windows Explorer Shell Extension that allows the user to right-click any file and compare both the SHA1 and MD5 checksums of a file. You can go further and click Compare and compare it against an original checksum (e.g. a downloaded file.)
Requirements:
Windows XP (Service Pack 3) or newer
.NET Framework 4.0
the .NET Framework 4.0 is available from Microsoft, just go to Microsoft's website and search ".NET Framework 4" and you should find it. (I am currently unable to post links.)
Directions:
Download ZIP file attached at the bottom of this post.
Extract it to a folder.
Run the Checksum Compareer.exe from the "x86 (32-bit)" folder if you're running 32-bit Windows, or from the "x64 (64-bit)" folder if you're running 64-bit Windows.
You can install the Windows Shell Extension by clicking "Tools" than "Install Explorer Extension"
When it asks to restart Windows Explorer, select Yes.
If you have installed it and would like to remove it, you can follow the same steps, but choose "Remove Explorer Extension."
Here are some screenshots of the extension once installed:
Images coming soon... (Under 10 posts currently... Sorry!)

[TOOL][WIN] ROM Explorer - Browse Android ROM Files

ROM Explorer
From time to time I need to extract some files from various Android ROMs. So far I downloaded the ROM file and then started to search for further tools to extract files from the downloaded ROM. If all went well I ended up with an image I could open with ext4_unpacker to finally extract the files I needed. This whole procedure took a lot of time, involved tools from unknown sources and often simply didn't work. So I decided to create my own tool.
ROM Explorer can directly open the following files:
zip archives with img or new.dat entries
Samsung md5 archives
Sony ftf archives
Huawei update.app archives
img/ext4 image files
lz4 image files (used by Samsung)
sin fies (used by Sony)
In case you have a file which is not supported let me know. Maybe I find the time to add support. Or simply add it yourself - ROM Explorer is Open Source.
Usage
Download the installer and run it or build your own version with Visual Studio 2017.
Start the executable. You will see a window similar to ext4_unpacker. In the first line you select a file, in the second line you can choose an archive entry if the file is an archive file.
Loading a file or archive entry can take a significant amount of time and disk storage. ROM Explorer may need to create temporary files with several gigabytes. A fast flash disk helps a lot!
You can extract files or folders by dragging and dropping them to Windows Explorer.
Downloads
ROM Explorer 0.9
ROM Explorer 0.9.1
Thanks To
ROM Explorer would not exist without the distributed knowledge of this forum. Especially I want to thank worstenbrood, Androxyde, IgorEisberg for their work.
So I'm waiting for your comments - but be patient it may take some time for me to react
Reserved for whatever purpose...
Wew
Let me try and report you back
Thank you I will try this out. Thanks too for making it open source

0.9.1 should fix this. Be sure to first uninstall before installing 0.9.1.
After hours of google search and downloading countless apps that dont work I found this. This app is legit and works on windows 10 64bit. Thank you for your work.
Your app is GREAT! Thanks for sharing it.
Edit: Answered my own question. Windows 10 tip "Run As Administrator" and dont drag files "to the desktop" but instead to an Explorer window.
Can this program find the differences between compiled ROMs?
I ask this question because Xiaomi on the Mi 9 released an initial kernel with sourcecode that was changed over time without updating the GitHub https://github.com/MiCode/Xiaomi_Kernel_OpenSource/tree/cepheus-p-oss and because of this change, the ROMs have something different between how they connect to the cameras. The old ROM versions (4/1/2019 and before) connect fine to the cameras, but post that date, a custom kernel built from the GitHub source will fail to connect to the cameras. Since the change has not been made open source on GitHub, there has to be another way to find and patch new kernel builds in order for them to work. Would your software be able to extract these changes? If not, do you have any other ideas which may? Much appreciated.
