Why I am getting SIGABRT whenever I am trying to load the native library.
I have already enabled the Hybrid debugging and given the path to the Symbols to \libs\armeabi in the Symbol Directories?
UPDATE :
Project structure is like this :
P1-> calls aar(P2)
aar library internally calls the native library(P3).
I have sources of all P1,P2 and the native code (P3)

Failed to load native library when i work with ndk functions in android studio. so please help me i am new for doing this and please correct me if wrong any where. Actually i was doing some scanning document using cardio sdk.
Basically i want to scan any document like cardio but i want to scan boundary not text or number only boundary of documents. if you have any other solution then please suggest me.
This is my activity code.
if (nUseNeon()) {
System.loadLibrary("cardioRecognizer");
Log.i(Util.PUBLIC_LOG_TAG, "Loaded card.io NEON library");
}
This is my error in my log cat.
Failed to load native library: JNI_ERR returned from JNI_OnLoad in "/data/app/com.surfaceview2-1/lib/arm/libcardioRecognizer.so"
Please check that:
1) you have the libcardioRecognizer.so library in the folder: app/src/main/jniLibs/armeabi of your Android Studio project
2) the library is compatibile with the architecture of the device you're using. If not, you can compile it and place in the folder:
app/src/main/jniLibs/armeabi-v7a (for arm-v7 architecture)
app/src/main/jniLibs/x86 (for x86 architecture)
I'm currently experimenting with Xamarin for the first time, as well as NUnitLite for the first time. I've set up a small Android project and a test project. In the Android project I make use of SqlLite, and in my test project I want to write some integration tests for my database insert/update/select methods.
However, when I run tests which includes a call to my class "GroupRepository" (which includes a type from the Mono.Data.Sqllite.dll in its constructor) I get the following exception. Note that I've also added the mentioned dll to my test-project.
TestInsertWithLegalValues (IntegrationTests.Repository.RepositoryTests.TestInsertWithLegalValues)
System.IO.FileLoadException : Could not load file or assembly 'Mono.Data.Sqlite, version=2.0.5.0, Culture=neutral, PublicKeyToken=0738eb9f132ed756' or one of its dependencies. Strong name validation failed. (Exception from HRESULT: 0x8013141A)
----> System.Security.SecurityException : Strong name validation failed. (Exception from HRESULT: 0x8013141A)
at Repository.GroupRepository..ctor()
at IntegrationTests.Repository.RepositoryTests.SetUp()
--SecurityException
The Android project targets API 8 using Xamarin 2.0. The test project is a Windows Console Application .NET 4.5.
Why is this failing the way it is?
Thanks for any input!
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.
I load the Android example NotePad and added one standard JavaThread, called TEST1.
When I look into the Threads of my NotePadApp (which does not execute native c/c++ code), I can observe the following:
My question is:
Does the Status "native" really mean that there's native c/c++
executing in these threads or does native has no connection to c/c++
code and the Android NDK / JNI stuff?
Would my Thread TEST1 also get status native if I load and execute c/c++ code?
i have class used with android frameworks, it calls icu4j's Arabicshaping. now i'v merged this class with another android branch that uses icu4c ( c implementation). but build process gives me error saying cannot find Arabicshaping...
searching in icu4c files shows me that it has both ArabicShaping.c and ushape.c
but i don't know how to call them from framewoks java code .
any idea? thanks
