How do I combine this two application class for Android Studio?

I have two application class which I want to combine in one, but provides two function, but I want it only one class so that I can call it on the application class in my manifest and get the App to produce both functions since i can not have two classes called on the application class in my manifest file in android studo.
I would like to put the AppController class in the App.Java class
Where I am confused is how to combine it since both extends different classes which java does not permit extending two classes in one.
Below is the App.java class
public class App extends MultiDexApplication implements Constants {
public static final String TAG = App.class.getSimpleName();
private RequestQueue mRequestQueue;
private ImageLoader mImageLoader;
private static App mInstance;
private ArrayList<Feeling> feelingsList;
private ArrayList<BaseGift> giftsList;
private SharedPreferences sharedPref;
private String username, fullname, accessToken, gcmToken = "", fb_id = "", photoUrl, coverUrl, area = "", country = "", city = "";
private Double lat = 0.000000, lng = 0.000000;
private long id;
private int state, allowRewardedAds = 1, admob = 1, ghost, pro, verify, balance, allowShowMyInfo, allowShowMyFriends, allowShowMyGallery, allowShowMyGifts, allowGalleryComments, allowComments, allowMessages, allowLikesGCM, allowCommentsGCM, allowFollowersGCM, allowGiftsGCM, allowMessagesGCM, allowCommentReplyGCM, errorCode, currentChatId = 0, notificationsCount = 0, messagesCount = 0, guestsCount = 0, newFriendsCount = 0;
#Override
public void onCreate() {
super.onCreate();
mInstance = this;
FirebaseApp.initializeApp(this);
sharedPref = this.getSharedPreferences(getString(R.string.settings_file), Context.MODE_PRIVATE);
this.readData();
if (Build.VERSION.SDK_INT <= Build.VERSION_CODES.KITKAT) {
try {
ProviderInstaller.installIfNeeded(this);
} catch (Exception e) {
e.getMessage();
}
}
}
// NB; I have some more codes in here which i am unable to put in full here.
}
}
Then this this the second class AppController.java
public class AppController extends Application {
private static Context mContext;
private static String mAppUrl;
public static MediaPlayer player;
public static Activity currentActivity;
#Override
public void onCreate() {
super.onCreate();
setContext(getApplicationContext());
mAppUrl = Constant.PLAYSTORE_URL + mContext.getPackageName();
setTelephoneListener();
player = new MediaPlayer();
mediaPlayerInitializer();
//AppCompatDelegate.setCompatVectorFromResourcesEnabled(true);
}
public static void mediaPlayerInitializer(){
try {
player = MediaPlayer.create(getAppContext(), R.raw.snd_bg);
player.setAudioStreamType(AudioManager.STREAM_MUSIC);
player.setLooping(true);
player.setVolume(1f, 1f);
} catch (IllegalStateException e) {
e.printStackTrace();
}
}
public static String getAppUrl() {
return mAppUrl;
}
private static void setContext(Context context) {
mContext = context;
}
public static Context getAppContext() {
return mContext;
}
public static void playSound()
{
try {
if (SettingsPreferences.getMusicEnableDisable(mContext)&&!player.isPlaying()) {
player.start();
}else{
}
} catch (IllegalStateException e) {
e.printStackTrace();
mediaPlayerInitializer();
player.start();
}
}
public static void StopSound() {
if (player.isPlaying()) {
player.pause();
}
}
private void setTelephoneListener() {
PhoneStateListener phoneStateListener = new PhoneStateListener() {
#Override
public void onCallStateChanged(int state, String incomingNumber) {
if (state == TelephonyManager.CALL_STATE_RINGING) {
StopSound();
} else if (state == TelephonyManager.CALL_STATE_IDLE) {
} else if (state == TelephonyManager.CALL_STATE_OFFHOOK) {
StopSound();
}
super.onCallStateChanged(state, incomingNumber);
}
};
TelephonyManager telephoneManager = (TelephonyManager) getAppContext().getSystemService(Context.TELEPHONY_SERVICE);
if (telephoneManager != null) {
telephoneManager.listen(phoneStateListener, PhoneStateListener.LISTEN_CALL_STATE);
}
}
#Override
protected void attachBaseContext(Context base) {
super.attachBaseContext(base);
MultiDex.install(this);
}
static
{
AppCompatDelegate.setCompatVectorFromResourcesEnabled(true);
}
}

Just Extend Your "AppController" class to "App" class. No need to do extra other work.
Like Below.
public class AppController extends App {
......
}

MulitdexApplication extends Application.
You could change your AppController to:
public class AppController extends MulitdexApplication
and then your App to
public class App extends AppController implements Constants

How to detect if it is Recents button, Multi Window mode or home button onUserLeaveHint()

In my app, I am relying on onUserLeaveHint() method when the user presses the home button, but this method is also being called when you are starting multi window mode in android 7.0 by long pressing "recents button" (which I don't want to perform same thing that I do when home button been pressed). So I want to know if there is a way to detect which is which. Cheers!
Note: onMultiWindowModeChanged() being called after onUserLeaveHint()

I think this is what you're looking for.
HomeWatcher mHomeWatcher = new HomeWatcher(this);
mHomeWatcher.setOnHomePressedListener(new OnHomePressedListener() {
#Override
public void onHomePressed() {
// do something here...
}
#Override
public void onHomeLongPressed() {
}
});
mHomeWatcher.startWatch();

import android.content.Context;
import android.content.Intent;
import android.content.IntentFilter;
import android.util.Log;
public class HomeWatcher {
static final String TAG = "hg";
private Context mContext;
private IntentFilter mFilter;
private OnHomePressedListener mListener;
private InnerRecevier mRecevier;
public HomeWatcher(Context context) {
mContext = context;
mFilter = new IntentFilter(Intent.ACTION_CLOSE_SYSTEM_DIALOGS);
}
public void setOnHomePressedListener(OnHomePressedListener listener) {
mListener = listener;
mRecevier = new InnerRecevier();
}
public void startWatch() {
if (mRecevier != null) {
mContext.registerReceiver(mRecevier, mFilter);
}
}
public void stopWatch() {
if (mRecevier != null) {

}

Not seeing the libs/sinch-android-rtc-3.8.0-VIDEO-SNAPSHOT.jar file in your project folder.You probably did not set it up correctly. Create a libs folder and then put this jar file in it.
If it still not working, I'd suggest to remove or comment out the class that requires the code from this libs/sinch-android-rtc-3.8.0-VIDEO-SNAPSHOT.jar, then follow this guide to install the external jar file, make sure your app compiles, then put back the class that you requires the code from this libs/sinch-android-rtc-3.8.0-VIDEO-SNAPSHOT.jar

Google recognizer and pocketsphinx in two different classes, how to loop them?

Yesterday i ask a simplified question of my problem, but think its too simplified.
What my programm should do, is to hear a keyword and when he hear it, he should listen to what i said. (like if you told to siri or google now, by saying siri or ok google).
I'm using pocketsphinx for the keyword and the google speechrecognizer for the longer parts. It works, but only for one time. The pocketsphinx is in the MainActivity and the google recognizer is in an extra class (Jarvis).
The programm starts with the pocketsphinx listener, when he hear the KEYPHRASE, he starts the google listener by calling jarvis.startListener() (by the next()-method) and there is the problem, when the googlelistener is done, i dont come back from the Jarvis-class to the MainActivity to call the next() method again.
(when the google recognizer is done, the last things he do is in the onResult() in Jarvis-class, but from there i cant call the next()-method from MainActivity-class)

You can store reference to the main activity in Jarvis object in a field:
class Jarvis {
....
private MainActivity m;
....
public Jarvis(MainActivity m) {
this.m = m;
}
....
public void onResults(Bundle results) {
....
m.next();
}
You can also send intents to the main activity as described here. This might be overkill in your case though.

how to call onOptionsItemSelected on a different activity

the FolderActivity runs on top of the MainActivty but the voice recognition in MainActivity is still active and I want the voice itself do some manipulation in the FolderActivity

Here's a few suggestions:
Have FolderActivity register a BroadcastReceiver as a listener for a certain Intent. When MainActivity wants to do something in FolderActivity, it can send a broadcast Intent which will be seen by the BroadcastReceiver in FolderActivity, which can then call the appropriate method in the `Activity.
When MainActivity wants to do something in FolderActivity, it can launch FolderActivity again using an Intent with flag Intent.FLAG_ACTIVITY_SINGLE_TOP and some "extra" that describes what FolderActivity should do. In FolderActivity override onNewIntent(), read the passed Intent parameter and use it to determine what method to call in FolderActivity. Because the Activity was launched withIntent.FLAG_ACTIVITY_SINGLE_TOP, Android won't create a new instance of the Activity, it will just callonNewIntent()` on the existing instance.
Have FolderActivity set a public static variable of type Activity to a reference to itself in onCreate(). MainActivity can then call a method on FolderActivity by doing something like FolderActivity.activityReference.doSomething()
Method 3 is not the preferred method, since you need to make sure that you set the public static variable to null in FolderActivity.onDestroy() and there are other concerns (timing issues, memory leaks, etc.) that need to be dealt with properly.
NOTE: You probably don't want to call onOptionsItemSelected() directly. This method is called by the Android framework when an options item is selected by the user. You should call directly the method that actually does something, not this framework callback method.
