I am currently trying to speed up the ProGuard process for projects using large libraries, such as scala-library.
I have made some solid progess, however, one thing stile evades me.
Here is the scenario I have so far and what is (not) working:
[WORKS] If the application hasn't been built already, ProGuard is ran over everything
[WORKS] If the app has been build already, but some new classes/methods from the big library have been used that havent been used before, run ProGuard over everything but with extra keep options
[FAILS] If the app has been built already, but the new version does not use any other classes than the ones that are already kept by ProGuard
Compile the source
Dex compiled classes
Merge the new, partial dex (app.dex) with current dex used in apk (classes.dex)
Package APK
The error I get using logcat is that the class MainActivity does not exist. The copy of my question (including the logcat log) can be found here.
Please help me, XDA. You're my only hope.
OK, this can be closed now, I figured it out. The answer is on StackOverflow
My App support minimum API 14 and above and i have used Support library everywhere.
Imported and used Support.Fragment all the time. but i am not sure whether do i really need if i am supporting API 14+.
and yes i have used few other libraries those supports api below 14. so do that require main app also should have support library ?
Please help & Suggest.
Thank you, and Happy new year in advance.
Hey, I couldn't fully understand so I will try to answer as best I can.
Support library v4 is updated as part of the SDK tools and your SDK manager; the purpose being not for legacy devices to be fully compatible, but for all the changes they make to not effect code which has been implemented previously.
For example, in recent changes they pushed the use of a non-static fragment hierarchy, but included updates to the support library for people who still want to make use of static fragments and not use childfragmentmanagers.
In short,
Even if you don't need to support older devices below API level 14 now, the support library will make sure that you can still support devices at API level 20 in 2 years time *hopefully* as it is updated automatically.
Any other questions feel free to ask,
Ryan

Hi! Does anyone here use Linux desktop distributions in chroot environment on Android device?
I am developing wayland protocol server for Android devices. If anyone is interested in checking my project, latest version of apk is always available here:
ftp://ftp.drivehq.com/mogryph/sparkle/
Currently I am only focused on running Xwayland as client. Also apk supports audio output.
Simplest instruction:
1. Android 6 or newer required, busybox required, root required
2. Prepare linux distribution in directory, image or on partition. Make sure you have Xwayland installed in it. Make sure you specify which DE to run (or at least xterm) in ~/.xinitrc
3. Install and start sparkle.apk
4. Press "edit user.sh", uncomment (remove #) line starting with start_generic_container. Change rest of this line to match your device:
first arg - image or partition where distribution is installed. If distribution is installed in directory and mouting is not needed, leave this arg unchanged.
second arg - mount point or directory with distribution. If you use mounting (first arg), this arg can be left unchanged.
third arg - name of the user which will be used to start Xwayland and DE. Its better to specify non-root. Also this is the user who must have .xinitrc in his home dir (see step 2).
5. Save user.sh and click "Start".
6. Any problems and crashes will be reflected in the log.
If you want audio output:
1. Compile and install driver from pcm_sparkle.tar.gz in your distribtion
2. cp 1.asoundrc ~/.asoundrc
If you have blinking problem, change upload_mode from 1 to 2 in settings. If you have bad performance, setting no_damage to true may help, but in most cases no_damage=false is better. Fastest upload mode is 0 (if it works).
If you don't trust me and don't want to give sparkle root permissions (I perfectly understand this) you don't have to. Also you can do without busybox.
But in this case, you need to understand and do a lot of things. Check sparkle's user.sh to get idea about what needs to be done. Basically:
1. You need to make /data/data/com.sion.sparkle/files accessible from inside chroot container. You can use bind bound.
2. Make sure you have tmpfs mounted over /tmp in container.
3. You may need to change selinux context on /tmp to match sparkle's context or disable SELinux.
4. You need to create new directory in /tmp, symlink sparkle's wayland socket from /data/data/com.sion.sparkle/files/wayland-0 to this dir. And export XDG_RUNTIME_DIR to point to this dir. Dir must be (ch)owned by user who will be running Xwayland and DE.
5. After all this, you can try to start Xwayland and your DE.

New version

Added x86 and x86_64 support. Actually it is rewritten almost from scratch but x86 support is the only thing others can notice...
Hello! This project is interesting. I tried you app and it works on my Xiaomi Redmi Note 4X(chromium and glmark from chrooted environment works very well)! Can you publish source code on Github, because it really interesting project?
Also I'm interested, please post it on github!
Did you put this up on github or move this thread? Looks very interesting.

Argh, sorry, I decided to abandon this project. You are free to delete thread. Also no copyleft-licensed components were used so I don't have to bother releasing sources.

Hello again.
For last two weeks I was rewriting it from scratch (yes. again... yes, third time).
Probably need another week to make it stable.
Currently I am not sure it runs on any device except my own 5-year old phone (LineageOS 14).
I will maintain last version here:
ftp://ftp.drivehq.com/mogryph/sparkle/
There is no English documentation, but you can see script "user.sh" to get idea about how to start xwayland. In most cases it should be enough to edit few lines in that script to make it work on another device. If you execute this script on your device with "install" argument, it is supposed to place itself into sparkle's directory and sparkle is supposed to run it ("start" function) automatically. Sparkle doesn't request root unless script does.
Here is video of sparkle working:
https://www.youtube.com/watch?v=tOSFYxCF7Q8
But it seems that KDE + video recording was too much for my old phone
Still, if you going to see video, don't close it until 2:00 where I turned of composition which caused lags.
Also on device everything looks much smoother than on video, even after 2:00.
When I watch fullscreen (1280x720) video on my device, sparkle + xwayland together add just 5% of CPU load (20% load of single core).
Thats it I guess... I tried to to discuss sparkle on 4pda.ru (russian forums), but got very bad reception. "xsdl is perfect, dont reinvent the wheel" they say. So I started to hate humanity and I decided to make sparkle personal project. Also this is last time I am solving reCAPTCHA to leave post on XDA.
Still alive
We are still alive. I've changed first post to reflect actual state. Now sparkle supports audio, auto-mouting containers and is lot more stable.
Yet there are still many things I want to improve in sparkle's core before adding new functions.
Also there are few demo videos on ftp.
Amazing!
Working great on my redmi 6 pro. Stock miui 9.9.3 rom. With linuxdeploy and sparkle from your ftp. No lag on visual and sound. My Linux distribution is alpinelinux arm64 arch.
Since first time I see your posting on 4pda. I'm interested in it. And finally it's on xda.
Thanks dev.

For anyone interested in the topic. Please follow the instructions in documentation from ftp. And Translate it to eng from rus.
This sounds amazing! Just curious, is it related to https://github.com/twaik/sparkle ?
I now have it working very well on my Samsung Tab S3 using Xwayland and a tiling window manager. Firefox runs amazingly well!
Is it meant to be used only with Xwayland or will it also work with native Wayland applications?
BTW, I think if you open sourced this project and promoted it a bit, it could become quite popular. It's basically the first way to run X11 GUI applications on Android devices at full speed. If you set up a donation link, you could also get compensated for your time and effort. I'll personally contribute $20 if it's open sourced, and I'm sure others will chip in as well.

Thanks for feedback. Nice to hear that someone managed to start this thing
Twaik's repository is clone of my very very old version of sparkle. I made that version years ago when I was just starting to learn linux and C++. Sparkle was rewritten from scratch two or three times since that version. And (I believe) current version is much better.
Regarding making it open source... Few months ago I had to find real job. Can't spend much time on personal projects any more. But I have my own strange programming style and my own vision of what sparkle should be. Not sure I want others to paint on my picture. It's probably all because of Twaik! I hate how he used old open source version of sparkle. He did terrible things to it, outraging all my beliefs Sorry!
P.S.: Yesterday I've uploaded another apk to my ftp. The file is called "sparkle-testing.apk". This version is much newer and has many fixes. But I've also changed to many things since tested version including some fundamental changes. No guarantee it will run at all on other devices. Interest is mega low and I get no test reports at all.
Hi Hentacler, I've just found your project - it looks really promising. Unfortunately, the only link currently working on this thread is to github. Is this project still live?
I have a samsung galaxy note 10+, and am using it as a laptop replacement. In addition to the android apps using Samsung Dex (Samsung's desktop solution), I have several linux distributions installed inside a chroot using userLand - so far, its working great. I'd be keen to give you project a try if it's still live, and am happy to help out with testing from my device.
Re open source - while I like your project, I'm not super interested in investing time into something that's not open sourced - I appreciate your concerns about wanting to maintain the direction, but having transparent development is pretty important to me. Is Twaik's fork of your project a better place to go?
Cheers.

Link to FTP should work and there you can get two versions:
sparkle.apk - old version, but confirmed to work by 3-4 people.
sparkle-testing.apk - latest version, but only briefly tested by me.
I don't ask anyone to invest anything... Sparkle doesn't request root access or any other dangerous permissions (unless you enable automatic container mounting and starting) so it's safe to try for anyone who wants.
Btw, somewhere between these two versions I've replaced BASH container initialization script with LUA version. That was probably a bad idea. LUA script is harder to start directly as root and hacks I used may not work (currently may even cause application freeze if root access is denied). Going to revert to BASH probably. But this only touches people who want sparkle to mount container and launch everything automatically on single button press.
p.s.: Why I need to solve captcha every time I post something?
Thanks for the new release! I've updated and everything seems to be working without any changes on my Samsung Tab S3 with chroot and Arch Arm Linux.
Your changes also solved the flickering for me! The old version would flicker the screen whenever my keyboard's trackpoint activated, but it's not flickering at all any more. Performance seems to be about the same.
I think this could be quite popular, but not many people know about it. Perhaps a post on Hacker News or Reddit would raise awareness.
I understand your position on open source and maintaining control. One idea if you haven't already considered it is releasing the code with a restrictive license that forbids any forks. But either way, I'm enjoying being to properly use X11 on my tablet.
BTW, have you tried any native Wayland compositors? I don't really understand the Wayland ecosystem that well. I gave Sway a brief try, but it didn't seem to work. I've only been using XWayland.
@Hentacler Thanks for your reply! Very keen to get this working, but having a few issues. I'm unsure how to configure the user.lua file - I'm using your latest apk.
I have a non-rooted device, and am running archlinux under termux. Works fine with xsdl. I have installed xorg-server-wayland for X11. I'd appreciate any advice you have.
@robsmith11 Are you able to share how you got this working on Arch? Thanks!!!!

I am not sure it is possible to use sparkle without root...
Sparkle makes it's directory accessible for everyone (chmod 777). Before Android 8 or 9 this was enough and xwayland from termux was able to connect to sparkle. Here is how people used to start it:
export XDG_RUNTIME_DIR=/data/data/com.sion.sparkle/files
Xwayland
But newer versions of Android brought more restrictions and termux can no longer connect to sparkle. These new restrictions are implemented using SELinux if you know what it is. Applications now have different security contexts.
But that is not all. Newest versions of android brought even more terrible meaningless restrictions effectively "killing" applications like termux and many others.
In short, from now one applications are not allowed to execute code (binary) that comes from "untrusted" sources. Termux used to download a lot of such code from it's own repositories. And now it can't. We can't even unpack binaries from assets.
So I can only help with rooted devices.
P.S. Please forgive me, but I am leaving this website. Making people solve recaptcha every time they want to post something is unacceptable level of contempt.
My mail: [email protected]
Thanks for that, will have a play. I could always just root my device. Weird about recaptcha, not having this issue. Currently through termux I have access to the whole sdcard, and am able to download packages (and distros) in it - will have a play and see what else is possible.
@tillum
I basically just followed the instructions on the first post for using Sparkle without busybox. I didn't need to modify the Lua scripts.
I'm guessing SELinux may be a problem without root. I'll try setting it up without root when I have a chance later.
Hello all,
(Note to mods: I'm too junior to post in Android Dev fora, so please someone move my post, I believe it's worthwhile as this is really useful)
I've updated my little known but highly useful 'bin dump' tool to work on Android 9 and later. This tool is like "service", able to list services, but not just In the normal namespace - also in the vndbinder (though that requires root).
The primary use of this tool is to list who's actually holding or using the service. There's a full explanation on how I accomplish this at the webpage - newandroidbook.com/tools/bindump.html (mods: please make this a link? I can't). This way you can see who's using "power", for example (i.e. holds wake locks) , or "SurfaceFlinger" (i.e. has activity views) or "activity" (i.e is an activity/service/broadcast receiver).
Unfortunately, the advanced use requires root, due to binder's debugfs entries being chowned and chmodded nowadays.
The tool DOES NOT use libbinder, and I effectively rewrote the whole thing in pure C with the low level ioctl()s. I support Android 9 and onwards (if you need insights to the parcel format, which changed three times in between these versions.. let me know). Should work everywhere - That said, I've seen idiosyncrasies in Samsung devices which I've accounted for. Feedback more than welcome.
I need a 32bit version , is source available?
Tool is not open source (too much secret sauce and re-implementation of libBinder from scratch) but I built a bdsm.armv7 binary and linked it from the download page
(direct: http://NewAndroidBook.com/tools/bdsm.armv7)
Thanks , will try that out
Hello, if you know what cSploit is you also probably knows that it's buggy and outdated.
I have taken time to rebrand the software, mixing versions, and modifying code.
My goal was to fix the login cracker which was not giving status output since the C regex was broken, so I re implemented the original dSploit 1.0 fashion - each tried passwords are shown - and the progress bar is effective. Also did modify the java code and res to be able to fully use hydra (more options, and most importantly being able to pass http related plugins parameters).
Metasploit is outdated, and ruby 1.9 cannot run the lattest version; so I switched to version 2.7, which is running: we can install gems.
Issue is that when downloading the MSF and setting it up, the bundle doesn't return, and gives no output. I don't know what is happening here, there may be a prompt for administrator's password so I run 'bundle install' as root, but it doesn't change anything.
gem install bundler does succeed, but not bundle install, showing forever "downloading gems". This part is tricky and I need people to look upon it with fresh eyes (I spent too much time on the code).
I'm calling the project eSploit and renamed a lot of things like package name, since I have been working alone and that the cSploit project is utterly abandoned, but still is delivered on platforms like nethunter store despite the bugs and EOF notice. So don't judge me on taking it over since no one cares.
Status is:
Nmap: fully functionnal
Hydra: restore not working (restore file's path issue)
Exploit finder: Not working since the MSF doesn't update yet -see above- , and that is the milestone.
MITM: not tested, might just get rid of it.
There is a change of strategy in the way we will retrieve exploits, instead of contacting outbound server and pass it the result of the inspector, then seeking in the metasploit database for the CVE, we will just pass the inspector's result to metasploit. No difference, and the thing will be working on local networks without internet connection,
To be honest this is a bit like pinning a nail with a bulldozer, but for now there is no alternative.
Submodules are removed from git, instead there's a big working tree with all the dependencies.
Note that the openssl library originaly shipped with the package doesn't 'work' with most newer software, hence are we using 1.1.1l for ruby, and will either stick to the lattest for older softwares (like hydra 8.8) or update the programs, so now only nmap is working.
So you tell me what you think of it, and don't hesitate to report bugs on github, ask me questions about the architecture of the software (originally designed by simone margaritelly), and help me finding a solution to the main issue.

This is very cool. It would be really cool if this is working. I hope that you can fix these Problems
cSploit, dSploit.. now eSploit i really like this program.
Any similarities with zANTI ?
I am very interested in this project! But the github page is offline Are you still working on this?
Hi people, I got to some reasoning that this was not needed, though being cool to have the metasploit framework for android, I remember now how younger I tried to hack into things without a proper vulnerability scanner. This results in frustration. You can't know just from an nmap scan what exploit to launch. This thing would be awesome with (for instance) greenbone. But as is it is like attacking tanks with guns.
So I dropped it and deleted the repository.
Thanks for your reactions.
