Failed to load native library - android

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)

TensorFlow Lite GPU delegate failure

I am trying to use TensorFlow Lite with GPU delegate on Android. I am using the lib version (.so files) built from sources from the master branch of the repo. The problem is: the ModifyGraphWithDelegate function always returns error. And there is the following error message in logs:
2019-04-22 15:21:16.212 688-688/com.my.app E/tflite: TfLiteGpuDelegate Prepare: Shader compilation failed: ERROR: 0:6: 'unknown' : not a legal layout qualifier id
ERROR: 0:6: 'unknown' : Syntax error: syntax error
INTERNAL ERROR: no main() function!
ERROR: 2 compilation errors. No code generated.
2019-04-22 15:21:16.212 688-688/com.my.app E/tflite: Node number 54 (TfLiteGpuDelegate) failed to prepare.
If I use JAVA/JNI prebuilt lib version ('org.tensorflow:tensorflow-lite:0.0.0-gpu-experimental') like in official example project - there are no such errors. But I really need to use C++ interface for my cross-platform code.
Any thoughts / suggestions appreciated.
If you're building native shared library then you might need to manually load the .so library.
See https://groups.google.com/a/tensorflow.org/forum/#!topic/tflite/5YhFsCFtKi4
I finally made it work. The internal reason of the error is still completely unknown for me but the point is:
The used (master branch) version of the TFLite GPU delegate for Android fails to properly prepare for running on GPU the standard (for regression task) output nodes combination = flatten + dense.
If replace it with reshape + convolution (pointwise) + squeeze, then it works fine.

Error while compiling Web RTC for Android

I am developing app of video chat in Web RTC.
I am going through documentation of Web RTC.
I have followed all steps mentioned for Getting the Code
export GYP_DEFINES="OS=android"
fetch --nohooks webrtc_android
gclient sync
I have all src code of web rtc in my root directory. As per documentation say we have to compile source to use in our application. Here i got error while compiling source using following command.
$ gn gen out/Default --args='target_os="android" target_cpu="arm"'
ERROR at //build/config/android/internal_rules.gni:636:3: Can't load input file.
import("//third_party/ijar/ijar.gni")
^-----------------------------------
Unable to load:
/Users/c86/webrtc-checkout/src/third_party/ijar/ijar.gni
I also checked in the secondary tree for:
/Users/c86/webrtc-checkout/src/build/secondary/third_party/ijar/ijar.gni
See //build/config/android/rules.gni:8:1: whence it was imported.
import("//build/config/android/internal_rules.gni")
^-------------------------------------------------
See //webrtc/examples/BUILD.gn:12:3: whence it was imported.
import("//build/config/android/rules.gni")
^----------------------------------------
See //BUILD.gn:13:5: which caused the file to be included.
"//webrtc/examples",
^------------------
How can I solve this? Am I going in right direction to develop app of video chat on Web RTC?
Building WebRTC for Android is only supported on Ubuntu(14 / 16).
Currently not supported in macOS.

what's wrong? search for help.

It seems like you are missing registration for your extension in your application.
Please take a look at sample projects for details. You can also start developing directly using sample projects in the SDK.

NUnitLite in Xamarin (Android). Unable to load Mono.Data.Sqllite.dll

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!
