Piotr answer is working for older version and Lorenzo DM's answer also valid but

mUnityPlayer = new UnityPlayer((ContextWrapper) getApplicationContext());

public class UnityPlayerActivity extends AppCompatActivity
{
    protected UnityPlayer mUnityPlayer; // don't change the name of this variable; referenced from native code
    ActionBar actionBar;
    private Toolbar toolbar;
    private FrameLayout unityContainer;

    // Setup activity layout
    @Override protected void onCreate (Bundle savedInstanceState)
    {
        super.onCreate(savedInstanceState);
        mUnityPlayer = new UnityPlayer(this);
        setContentView(R.layout.activity_unity_player);
        mappingWidgets();
        init();

    }

    void  mappingWidgets(){
        toolbar = (Toolbar) findViewById(R.id.toolbar);
        unityContainer = (FrameLayout) findViewById(R.id.unity_container);
        FrameLayout.LayoutParams layoutParams = new FrameLayout.LayoutParams(FrameLayout.LayoutParams.MATCH_PARENT, FrameLayout.LayoutParams.MATCH_PARENT);
        unityContainer.addView(mUnityPlayer.getView(), 0, layoutParams);
        mUnityPlayer.requestFocus();

    }
    void init(){
        setSupportActionBar(toolbar);
        actionBar = getSupportActionBar();
        if (actionBar != null)
            actionBar.setDisplayHomeAsUpEnabled(true);
        toolbar.setNavigationOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                finish();
                onDestroy();
            }
        });
        setTitle(getString(R.string.app_name));


    }


    @Override protected void onNewIntent(Intent intent)
    {
        setIntent(intent);
    }

    // Quit Unity
    @Override protected void onDestroy ()
    {
        mUnityPlayer.quit();
        super.onDestroy();
    }

    // Pause Unity
    @Override protected void onPause()
    {
        super.onPause();
        mUnityPlayer.pause();
    }

    // Resume Unity
    @Override protected void onResume()
    {
        super.onResume();
        mUnityPlayer.resume();
    }

    // Low Memory Unity
    @Override public void onLowMemory()
    {
        super.onLowMemory();
        mUnityPlayer.lowMemory();
    }

    // Trim Memory Unity
    @Override public void onTrimMemory(int level)
    {
        super.onTrimMemory(level);
        if (level == TRIM_MEMORY_RUNNING_CRITICAL)
        {
            mUnityPlayer.lowMemory();
        }
    }

    // This ensures the layout will be correct.
    @Override public void onConfigurationChanged(Configuration newConfig)
    {
        super.onConfigurationChanged(newConfig);
        mUnityPlayer.configurationChanged(newConfig);
    }

    // Notify Unity of the focus change.
    @Override public void onWindowFocusChanged(boolean hasFocus)
    {
        super.onWindowFocusChanged(hasFocus);
        mUnityPlayer.windowFocusChanged(hasFocus);
    }

    // For some reason the multiple keyevent type is not supported by the ndk.
    // Force event injection by overriding dispatchKeyEvent().
    @Override public boolean dispatchKeyEvent(KeyEvent event)
    {
        if (event.getAction() == KeyEvent.ACTION_MULTIPLE)
            return mUnityPlayer.injectEvent(event);
        return super.dispatchKeyEvent(event);
    }

    // Pass any events not handled by (unfocused) views straight to UnityPlayer
    //@Override public boolean onKeyUp(int keyCode, KeyEvent event)     { return mUnityPlayer.injectEvent(event); }
    // Pass any events not handled by (unfocused) views straight to UnityPlayer
    @Override public boolean onKeyUp(int keyCode, KeyEvent event)     {
        if(keyCode == KeyEvent.KEYCODE_BACK) {
            finish();
            onDestroy();
            return true;
        }
        return mUnityPlayer.injectEvent(event); }
    @Override public boolean onKeyDown(int keyCode, KeyEvent event)   { return mUnityPlayer.injectEvent(event); }
    @Override public boolean onTouchEvent(MotionEvent event)          { return mUnityPlayer.injectEvent(event); }
    /*API12*/ public boolean onGenericMotionEvent(MotionEvent event)  { return mUnityPlayer.injectEvent(event); }
