[Q] Can I Add Android Code In Java Package?

Hi,
I am trying to add some code to the File.java in java package that is located at
Code:
libcore/luni/src/main/java/java/io
in the android 4.4 stock source. For a start I would like to write some output to the LogCat via
Code:
Log.d(TAG, "File I/O happening from process " + Process.myUid());
Since File.java is in the plain java package, it does not know about Android code, so simply importing the android class in the header of the class does not work I assume.
I am pretty new to modifying the stock so I was wondering, is this even possible?
Thank you in advance.

ffmpeg: Build failed in windows with cygwin for Android

I have trying building ffmpeg for android using windows 7 and Cygwin. I have android-ndk-r9d.
I have download the source code from here
I have already set NDK environment variable. And updated TOOLCHAIN line to: TOOLCHAIN=echo $NDK/toolchains/arm-linux-androideabi-4.8/prebuilt/windows-x86_64 because linux folder not present.
After running ./build.sh command. I got following error:
arm-linux-androideabi-gcc is unable to create an executable file.
C compiler test failed.
If you think configure made a mistake, make sure you are using the latest
version from SVN. If the latest version fails, report the problem to the
[email protected] mailing list or IRC #ffmpeg on irc.freenode.net.
Include the log file "config.log" produced by configure as this will help
solving the problem.
Help me to find out what I did wrong?

Android Studio - JDK - Recommended versions and settings on Windows XP 32-bit?

My aims:
- Use Android Studio to develop a basic Android application - should be possible
- Use Android Studio to back up my physical phone (Hisense phone running Nougat 7.0) and create an emulated version of it running on my PC - should be possible, is it?
My PC:
- Windows XP 32-bit
- Pentium Dual Core T2330 processor NOT supporting Intel® Virtualization Technology (VT-x)
- 2 GB RAM
Questions:
- Are the above aims possible to achieve with my PC?
- If yes, what are the recommended Android Studio and Java SE Development Kit versions/settings to use that work for sure?
Story: I have tried to use Android Studio 3.0.1 with various versions of Java SE Development Kit 8 (including 121, 144, and 152) and various settings/hacks constantly running into various bugs/issues, most of which were seemingly resolved by new settings/hacks, yet I ended up with the same error messages after I have tried everything I have found online that nice people suggested on forums.
I am unable to even compile and run a default Android app, I get these error messages:
Gradle build finished with 2 error(s) in 21s 591ms
Error:java.util.concurrent.ExecutionException: java.lang.RuntimeException: No server to serve request. Check logs for details.
Error:Execution failed for task ':app:mergeDebugResources'.
> Error: java.util.concurrent.ExecutionException: java.lang.RuntimeException: No server to serve request. Check logs for details.
I am unable to run a default-loaded Android Virtual Device, I get this error message:
Emulator: Process finished with exit code -1073741511 (0xC0000139)
I am clueless how to continue. If my aims are possible to achieve, could someone tell me the Android Studio and JDK versions and settings that work 100% under 32-bit Win XP?
Thanks in advance!

[APKMULTITOOL] Error when signing (sign apk with android market 13 & 7 zip, sign, in)

[APKMULTITOOL] Error when signing (sign apk with android market 13 & 7 zip, sign, in)
Hello folks, I have stumbled upon a small problem using APKMultiTool ...
When I try to sign my apk (It's a unity apk meaning I only edited 1 of the dll files.) It fails.
The error it gives me, even in log (26) is useless.
Code:
--------------------------------------------------------------------------
|26-07-2018 -- 13:55:05,73|
--------------------------------------------------------------------------
java version "10.0.2" 2018-07-17
Java(TM) SE Runtime Environment 18.3 (build 10.0.2+13)
Java HotSpot(TM) 64-Bit Server VM 18.3 (build 10.0.2+13, mixed mode)
Press any key to continue . . .
I do have the environment path for system, directed to my JDK java path.
The APKMultiTool is opened with Administrator and it's at root(c:\APKMultiTool) <
Heres the code it gives me at the end of option 7: (zip, sign & install)
Code:
Compressing res\layout\com_facebook_placepickerfragment_list_row.xml
Compressing res\layout\com_facebook_search_bar_layout.xml
Compressing res\layout\com_facebook_tooltip_bubble.xml
Compressing res\layout\com_facebook_usersettingsfragment.xml
Everything is Ok
Signing Apk
Usage: signapk [-w] publickey.x509[.pem] privatekey.pk8 input.jar output.jar
"An Error Occurred, Please Check The Log (option 26)"
The error afterwards in the log file and when using 26, is still the same.
Now I'm going to just try to sign the unsigned apk. First the one that was just zipped.
I do this with option 13: Sign apk with android market
Code:
Please make your decision:13
*Notice this option requires you to have the Java JDK installed before this option will function*
*Notice you need to go into your Environment Variables and set the path to your JAVA_HOME*
*For example define it as C:\Program Files\Java\jdk1.6.0_43 as a system variables slot not the User Variables*
Press any key to continue . . .
Signing Apk
Only one alias can be specified
Please type jarsigner -help for usage
"An Error Occurred, Please Check The Log (option 26)"
I am unable to type jarsigner -help, in CMD it does not exist as a command, and in APKMT it closes the prompt. The log file and 26 gives me the same error text so far, meaning it was not even updated.
(Note: I open ALL prompts as Administator, also APKMT)
I am at a complete loss...
Would be really grateful for input :3 thanks a lot.
-EDIT-
Am unable to install unsigned apk on rooted bluestacks 3n device. :3
... I found out that if I used the new tool
https://forum.xda-developers.com/an...tool-apk-easy-tool-v1-02-windows-gui-t3333960
APK Easy Tool, everything became more organized and much easier to work with. I got it working and are happy to say that my first mod was succesful, yay.
Happy modding everyone
For reference, the apk I modded was Galactic Rush for Android

SDL Error,dlopen failed

I downloaded an app but it requires android 5.0+ ,so i changed the min sdk version to the lowest ,then i successfully installed but after running it an error came, Dlopen failed: cannot locate the symbol "atof" referenced by "libpng16.so..
My phone- Galaxy Grand 2(SM-G7102).
Android version-KitKat(4.4.2).
Please Let me know if there is any solution.
I've also got a problem it installs but it can locate atof symbol on my huawei media tab 4.4.4 kit kat
If an app is compiled to be run on an Android 5.+ device then app will crash when you run it on an Android 4.x device - this because Android 4.x doesn't have any of Android 5 APIs.
