Develop Reference

Can we debug the APK with ASAN active on Android Studio?

My project is a simple game with native C++ code and Java, which uses cmake to compile C/C++ code. I'm using address sanitizer to check my the code. I follow the instruction here
My OS is windows 10 64bit.
However, when I press debug on Android Studio, I got the message as
2020-03-19 13:50:56.946 5152-5152/? E/logwrapper: executing /data/app/com.indie.haiphan.Breakout-ZFFz_f8ETleajrgP6rg9gw==/lib/arm64/wrap.sh failed: No such file or directory

2020-03-19 13:50:56.957 873-873/? W/Zygote: Error reading pid from wrapped process, child may have died
I checked on my APK (with Analyze APK of Android Studio) the wrap.sh exist.
So my question is I can't debug with wrap.sh inside the APK?
Thanks

You probably have BOM or an extra carriage return at the end of the first line of your wrap.sh. Which is possible in windows.
To fix it you can use dos2unix tool.

Xamarin MultiDex in VisualStudio 2015

Hi everybody I'm in a dead end!
Develop a PCL application using VisualStudio 2015, Xamarin and MvvmCross.
The Android app exceeds the 65K limit. I need to use Multidex!
For its implementation I have undertaken these guidelines:
Enabled checkbox for MultiDex
Extended MultiDexApplication class
General considerations:
Debug mode
MinSdk: 21
TargetSdk: 25
BuildTools: 23.0.3
Jdk 1.8.0_121
Xamarin.Android 7.3
Results:
"java.exe" exited with code 2. C:\Program Files (x86)\MSBuild\Xamarin \Android\Xamarin.Android.Common.targets 1965
<!-- Compile java code to dalvik -->
<CompileToDalvik
DxJarPath="$(DxJarPath)"
JavaToolPath="$(JavaToolPath)"
JavaMaximumHeapSize="$(JavaMaximumHeapSize)"
JavaOptions="$(JavaOptions)"
ClassesOutputDirectory="$(IntermediateOutputPath)android\bin\classes"
ToolPath="$(DxToolPath)"
ToolExe="$(DxToolExe)"
UseDx="$(UseDx)"
MultiDexEnabled="$(AndroidEnableMultiDex)"
MultiDexMainDexListFile="$(_AndroidMainDexListFile)"
JavaLibrariesToCompile="#(_JavaLibrariesToCompileForAppDx)"
OptionalObfuscatedJarFile="$(IntermediateOutputPath)proguard\__proguard_output__.jar"
/>
The error occurs during the compilation process.
I have consulted these sources:
"https://developer.android.com/studio/build/multidex.html"
"http://www.jon-douglas.com/2016/09/05/xamarin-android-multidex/"
"http://www.jon-douglas.com/2016/09/23/xamarin-android-multidex-keep/"
"https://przemekraciborski.eu/"
"https://forums.xamarin.com/discussion/64234/multi-dex-app-with-a-custom-application-class-that-runs-on-pre-lollipop"
"http://frogermcs.github.io/MultiDex-solution-for-64k-limit-in-Dalvik/"
I also have the ClassyShark.jar tool, but no dex or apk file is generated to explore it. Only the mono.android.jar file exists
Please I need help.
Thank you very much.

This is likely to be caused by an issue between Xamarin and ProGuard, the fix to which is detailed here. Essentially, you need to replace the proguard.jar file that is in your Android SDK directory with the latest one from SourceForge (v5.3.3 currently).
EDIT: Per the error messages in your edits, the --multi-dex option isn't being passed during compilation. I would check your Android .csproj to make sure that the <AndroidEnableMultiDex> option is set to True for all build configurations. If that doesn't help, you may need to upload a reproducible sample somewhere.
EDIT 2: Per the comments, your Android SDK location needs to be somewhere where the path does not contain spaces. Program Files is no good. Personally I put mine in C:\Android\android-sdk.

After adjusting the path to the android sdk, removing the spaces and setting in the project file for the Droid platform the property AndroidEnableMultiDex in all configurations (appeared AndroidEnableMultipleDex) in true, I was able to compile without errors. Also, I have been able to check the contents of the generated dex files and both have references to Mvvmcross.
When I execute the application, it shows the splash view (ok!!!), but, an exception occurs when processing the view (activity) that has a binded viewmodel. Now, the viewmodel has null value. (Until the moment of having to activate the multidex, the application executed without any incidence)
My challenge now is to know if all the reference to Mvvmcross should be in the main dex, or is it due to another problem that I have overlooked?
Thanks in advance for his time to #LukePothier.
My self response:
After compiling and generate dex classes:
use dex2jar & jd-gui tools following Jon Douglas' hints in http://www.jon-douglas.com/2016/09/23/xamarin-android-multidex-keep/.
be very patient and persevere.
remove innesesary code and plugin if you can do it yourself.
I already have the application running !!!

RIDE.. Getting [Error 2] The system cannot find the file specified when using Robot framework for Android library

Im trying to build automation test cases using robot framework for android devices.
I have imported the android library and have installed python on my system.
My code is as follows:
*** Settings ***
Library OperatingSystem
Library Selenium2Library
Library AndroidLibrary
*** Test Cases ***
case1
Start Emulator avd_name='AVD_for_Nexus_5_by_Google',no_window=False, language=en, country=us
Wait For Device timeout=120
Press Menu Button
Stop Emulator
When I try to execute a test case, I get the error:
command: pybot.bat --argumentfile c:\users\kesav\appdata\local\temp\RIDEnhapet.d\argfile.txt --listener C:\Python27\lib\site-packages\robotframework_ride-1.3-py2.7-win32.egg\robotide\contrib\testrunner\TestRunnerAgent.py:52956:False C:\Users\kesav\test
[Error 2] The system cannot find the file specified.
I have checked the PATH environment variable, it contains C:\Python27 and C:\Python27\Scripts as well.
Please help!

First thing you are missing something from you path, make sure you path has:
;C:\Python27;C:\Python27\Scripts;C:\Python27\Lib\site-packages
You are missing site-packages from your path, try that and get back to me!

mk:1: *** missing separator. android NDK

I am trying to compile some source code but when i run the command
make -f android-9-armv7.mk
I get the following error
android-9-armv7.mk:1: * missing separator. Stop.
This is the contents of the file above:
And I have set the IMAGINE_PATH variable as well, cant seem to figure it out.
link ../imagine/make/shortcut/common-builds/android-9-armv7.mk
Compiling instructions
http://code.google.com/p/emu-ex-plus-alpha/wiki/Compiling
Imagine is locaed at C:/Imagine

I don't know where you've taken the sources, but all the android-9-armv7.mk files from different projects on that git has following content:
../imagine/make/shortcut/common-builds/android-9-armv7.mk
...there is no link keyword, which probably is why you get this error.
Also, please be informed that you're building this on Windows machine while documentation clearly states that it's supported only on Linux and Mac OS X.

Android NDK build: File not found Error

Need your guidance, I am writing one app in android with the help of native code which will communicate with CAN (Controller Area Network) port ; for that in my C code i used linux/can.h header file. and i am following "http://mobilepearls.com/labs/ndk-builder-in-eclipse/" this link to build my app. but one i set all thing i got bellow msg in eclipse console box
Compile thumb : can_port <= cansend.c
jni/cansend.c:14:23: fatal error: linux/can.h: No such file or directory
compilation terminated.
make: *** [obj/local/armeabi/objs/can_port/cansend.o] Error 1
One more thing, i am working on windows environment. But i don't think this may be cause.

It is correct that it is not a Windows/Linux problem. The simple problem is that compiler is unable to find the file can.h. Now, for your info, when the compiler starts compiling, it searches for its header files in the folder
C:\(path to NDK folder)\platforms\(android-version)\(arch)\usr\include\linux
Now, if there isn't a can.h there, the compiler will flag an error. So the best way is
Either copy can.h to the above path (not tested)
Modify your Makefile to path to the correct directory where this header file is kept
Hope this helps!
