I am trying to debug my iOS to android conversion and find this warning:
warning: .dynamic section for "/Users/MacUser/.apportable/cache/devices/033f426d/libs/libxml2.so" is not at the expected address (wrong library or version mismatch?)
warning: Could not load shared library symbols for 8 libraries, e.g. libdiag.so.
Use the "info sharedlibrary" command to see the complete listing.
Do you need "set solib-search-path" or "set sysroot"?
The thing is the file exists at the path specified. Totally lost as to why this warning is occurring. Any ideas/input? Oh also i forgot to mention i ran the command [info sharedLibrary] it returns nothing
Un-copied library:
pull: /system/lib/libxt_native.so -> /Users/MacUser/.apportable/cache/devices/033f426d/libs/libxt_native.so
failed to copy '/system/lib/libxt_native.so' to '/Users/MacUser/.apportable/cache/devices/033f426d/libs/libxt_native.so': No such file or directory
try doing apportable clean_device_cache and running again

When I use ANativeWindow_setBuffersDataSpace in NDK,it prompts no error.But I build the project,the logcat shows that
"undefined reference to ANativeWindow_setBuffersDataSpace'clang++: error: linker command failed with exit code 1 " . However I can find this API in native_window.h "__INTRODUCED_IN(28);"and I set minsdk 28.
Add libnativewindow.so to linked libraries, e.g. if you use CMake:
add_library(MainActivity SHARED MainActivity.cpp)
target_link_libraries(MainActivity
android
native_app_glue
EGL
GLESv1_CM
nativewindow

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

MultiDexMainDexListFile="$(_AndroidMainDexListFile)"

/>
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/"

"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 !!!
I'm trying to explore the tensorflow android demo. I want to adapt the app using android studio.
However when I simply follow the instructions I get compilation errors no matter what I do:
Trying to compile tensorflow using bazel and NDK r12b:

switching aroung java-versions to see whether the bazel compiling issues come from there:
$sudo update-alternatives --config java

No luck so far :-/. Has anyone successfully compiled tensorflow for android from source?
What version of Tensorflow, NDK, bazel, java are required / compatible with each other? Do I really need bazel? (never worked with it anyway) Can't I just compile the android demo in android-studio like any other app?
I'm using Ubuntu 14.04, Cuda8.0, cudnn_v5.1, Titan X Pascal (not sure if these things matter)
Installing Bazel on Ubuntu can be done without compiling.
Follow all steps of the dedicated documentation: Install Bazel on Ubuntu
The issue is when trying to build a signed APK, it errors at the last step with this:
[2013-06-20 11:39:34 - MyApp] Proguard returned with error code 1. See console
[2013-06-20 11:39:34 - MyApp] Unable to access jarfile /Users/rob/Android
I am using the latest Eclipse ADT v22.0.1-685705 (just installed this morning) and it seems like this issue has been around for at least a month now according to Google.
In order to fix this,
Change:
java -jar $PROGUARD_HOME/lib/proguard.jar "$#"
To:
java -jar "$PROGUARD_HOME/lib/proguard.jar" "$#"
in this file <Android SDK Location Here>/sdk/tools/proguard/bin/proguard.sh

I copied the sample of Google breakpad for Android and added it to my project. I had first a problem to get the minidumps (I was triggering SIGSEGV errors but nothing was written on my SD card). I finally managed to get some minidumps (I don't really know how but that's not my main problem).
My problem is that I can't dump the symbols of my native libraries, it says the following error message :
dump_syms.exe libcppinterface.so > libcppinterface.so.sym
loadDataForPdb and loadDataFromExe failed
Open failed
Thanks for your help
The Breakpad tools are not very cross-platform friendly. You need to build dump_syms on a Linux machine in order to get a dump_syms binary that can read ELF/DWARF and produce debug symbols from your Android binaries. The Windows dump_syms.exe is only used for dumping symbols from MSVC-produced PDB files.
