I'm trying to build SFML app for android, but getting some strange errors.
First, my app configured like that:

Android.mk

LOCAL_PATH := $(call my-dir)

include $(CLEAR_VARS)

LOCAL_MODULE := sfml-example

LOCAL_SRC_FILES := main.cpp

LOCAL_SHARED_LIBRARIES := sfml-system
LOCAL_SHARED_LIBRARIES += sfml-window
LOCAL_SHARED_LIBRARIES += sfml-graphics
LOCAL_SHARED_LIBRARIES += sfml-audio
LOCAL_SHARED_LIBRARIES += sfml-network
LOCAL_SHARED_LIBRARIES += sfml-activity
LOCAL_SHARED_LIBRARIES += openal
LOCAL_WHOLE_STATIC_LIBRARIES := sfml-main

include $(BUILD_SHARED_LIBRARY)

$(call import-module,third_party/sfml)

Application.mk

NDK_TOOLCHAIN_VERSION := 4.9
APP_PLATFORM := android-19
APP_STL := c++_static
APP_ABI := all
APP_MODULES := sfml-activity sfml-example
APP_OPTIM := release
APP_CFLAG := -g -O3

It's compiled and work fine on Android 5,6,7. But when I tried to launch app on android 6.0 I got an error:

java.lang.RuntimeException: Unable to start activity ComponentInfoorg.sfml_test.android/android.app.NativeActivity: java.lang.IllegalArgumentException: Unable to load native library: /data/app/org.sfmldev.android-1/lib/arm/libsfml-activity.so

I found similar problem in this question.
So I tried to write activity, which should load SFML lib. Activity code:

package org.sfmldev.android;

import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;


public class SFMLLoader extends Activity 
 static 
 System.loadLibrary("sfml-activity");
 System.loadLibrary("sfml-example");
 
 @Override
 protected void onCreate(Bundle savedInstanceState) 
 super.onCreate(savedInstanceState);

 Intent intent = new Intent(SFMLLoader.this, android.app.NativeActivity.class);
 SFMLLoader.this.startActivity(intent);
 

And i change my AndroidManifest.xml:

<?xml version="1.0" encoding="utf-8"?>

<manifest xmlns:android="http://schemas.android.com/apk/res/android"
 xmlns:tools="http://schemas.android.com/tools"
 package="org.sfmldev.android">

 <uses-feature android:glEsVersion="0x00010001" />

 <uses-permission android:name="android.permission.VIBRATE" />


 <application android:label="@string/app_name"
 android:icon="@drawable/sfml_logo"
 android:hasCode="false"
 android:allowBackup="false"
 android:testOnly="false"
 tools:ignore="GoogleAppIndexingWarning">

 <activity android:name="org.sfmldev.android.SFMLLoader"
 android:label="@string/app_name"
 android:configChanges="keyboardHidden|orientation|screenSize">
 <intent-filter>
 <action android:name="android.intent.action.MAIN" />
 <category android:name="android.intent.category.LAUNCHER" />
 </intent-filter>
 </activity>

 <activity android:name="android.app.NativeActivity"
 android:label="@string/app_name"
 android:icon="@drawable/sfml_logo"
 android:configChanges="keyboardHidden|orientation|screenSize">

 <meta-data android:name="android.app.lib_name" android:value="sfml-activity" />
 <meta-data android:name="sfml.app.lib_name" android:value="sfml-example" />

 </activity>
 </application>
</manifest>

And now I have new error on any devices:

java.lang.RuntimeException: Unable to instantiate activity ComponentInfoorg.sfmldev.android/org.sfmldev.android.SFMLLoader: java.lang.ClassNotFoundException: Didn't find class "org.sfmldev.android.SFMLLoader" on path: DexPathList[[directory "."],nativeLibraryDirectories=[/vendor/lib, /system/lib]]

I'm already tried to make relative path, disable instance run, clean project, restart android studio, restart OS, delete .idea and .gradle

You are supposed to load your library on runtime not on activity create:

public class SFMLLoader extends Activity 
 static 
 System.loadLibrary("sfml-activity");
 System.loadLibrary("sfml-example");
 

 @Override
 protected void onCreate(Bundle savedInstanceState) 
 super.onCreate(savedInstanceState);
 ...
 

Just forgot to remove android:hasCode="false" from AndroidManifest.xml
