i was looking for a torrent library for android and came-across ttorrent
.when i tried to add dependencty to gradle it gave me errors regarding slf4j-log4j12.
i ended up adding all jar files manually and managed to run the app using sample code.
But i am getting this error now.
ClassLoader referenced unknown path: /data/app/com.test.torrent-1/lib/arm64

As I understand bitcoinj library contains wrapper for bitcoin-core functions - NativeSecp256k1. I am trying to call one of methods from this wrapper:
NativeSecp256k1.secKeyVerify(byteArrayOf(...))
But I got a crash:
java.lang.UnsatisfiedLinkError: No implementation found for int

It looks like bitcoinj library contains the wrapper but doesn't contains native library which used in this wrapper. How to fix this issue?
Bitcoinj uses JNI to load a C library for secp256k1 curve operations. If the lib is imported correctly... and since you are trying to access it directly, you might be missing the System.loadLibrary('secp256k1') call
Check here : https://github.com/bitcoinj/bitcoinj/blob/2ec193f8479425c3a66bebf5f2d3493e39e88f7c/core/src/main/java/org/bitcoin/Secp256k1Context.java
To build the compiles sources for the lib, its describes in the comment block of the NativeSecp256k1 class, here : https://github.com/bitcoinj/bitcoinj/blob/2ec193f8479425c3a66bebf5f2d3493e39e88f7c/core/src/main/java/org/bitcoin/NativeSecp256k1.java#L34
I have followed the directions here OpenCV in Android Studio the one that has 94 votes. I get this error when I dod System.loadlibrary("opencv-java")

Whats the problem?
Edit2: Now I got problem of Android NDK: Your APP_BUILD_SCRIPT points to an unknown file: /Users/KrikorHerlopian/Downloads/adt-bundle-mac-x86_64-20140702/sdk/ndk-bundle//jni/Android.mk when i try running my app from the terminal using /Users/KrikorHerlopian/Downloads/adt-bundle-mac-x86_64-20140702/sdk/ndk-bundle/ndk-build

I am not getting the main issue behind crashing because I am a newbie in android. Please guide me to solve the problem.
Thanks.
I'm trying to implement functionality similar to Android Keystore Direct access. The code is making use of IPC and an exception is thrown when mRemote.transact was called (IKeystoreService.java line 54)
This works well on versions of Android before Marshmallow (API 23). I know the permissions model has changed since.
The exception is:
java.lang.RuntimeException: Unable to start activity ComponentInfo{com.example/com.example.activity.MainActivity}: java.lang.SecurityException

Is there a particular permission I need to check for during runtime? Or is this another problem altogether?
