Why not working:
In 7.1 everything is working fine i get the call and the chathead apears.
In 4.4 [LG] I receive the call but nothing happens.
In 4.4 [BQ] Aplication crashes.
Any help?

Found the problem.
Where I'm calling startActivity from outside an activity like:
context.startActivity(new Intent(context, FloatingActivity.class)
.putExtra("PHONE", TelephonyManager.EXTRA_INCOMING_NUMBER));
in android 4.4 it is required to set the flag Intent.FLAG_ACTIVITY_NEW_TASK
o in all ocurrencies i need to call it like:
context.startActivity(new Intent(context, FloatingActivity.class)
.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK)
.putExtra("PHONE", TelephonyManager.EXTRA_INCOMING_NUMBER));

Show a popup when user click on Overlay button

I have an Overlay Button in my Android app. I want to show a layout and interact with the views of my Layout when the user click on the button.
For the moment, I show a Toast. How can I do that ?
This is my OverlayShowingService.class :
public class OverlayShowingService extends Service implements OnTouchListener, OnClickListener {
private View topLeftView;
private Button overlayedButton;
private float offsetX;
private float offsetY;
private int originalXPos;
private int originalYPos;
private boolean moving;
private WindowManager wm;
#Override
public IBinder onBind(Intent intent) {
return null;
}
#Override
public void onCreate() {
super.onCreate();
wm = (WindowManager) getSystemService(Context.WINDOW_SERVICE);
overlayedButton = new Button(this);
overlayedButton.setText("Overlay button");
overlayedButton.setOnTouchListener(this);
overlayedButton.setBackgroundColor(Color.BLACK);
overlayedButton.setOnClickListener(this);
WindowManager.LayoutParams params = new WindowManager.LayoutParams(WindowManager.LayoutParams.WRAP_CONTENT, WindowManager.LayoutParams.WRAP_CONTENT, WindowManager.LayoutParams.TYPE_SYSTEM_ALERT, WindowManager.LayoutParams.FLAG_NOT_FOCUSABLE | WindowManager.LayoutParams.FLAG_NOT_TOUCH_MODAL, PixelFormat.TRANSLUCENT);
params.gravity = Gravity.LEFT | Gravity.TOP;
params.x = 0;
params.y = 0;
wm.addView(overlayedButton, params);
topLeftView = new View(this);
WindowManager.LayoutParams topLeftParams = new WindowManager.LayoutParams(WindowManager.LayoutParams.WRAP_CONTENT, WindowManager.LayoutParams.WRAP_CONTENT, WindowManager.LayoutParams.TYPE_SYSTEM_ALERT, WindowManager.LayoutParams.FLAG_NOT_FOCUSABLE | WindowManager.LayoutParams.FLAG_NOT_TOUCH_MODAL, PixelFormat.TRANSLUCENT);
topLeftParams.gravity = Gravity.LEFT | Gravity.TOP;
topLeftParams.x = 0;
topLeftParams.y = 0;
topLeftParams.width = 0;
topLeftParams.height = 0;
wm.addView(topLeftView, topLeftParams);
}
#Override
public void onDestroy() {
super.onDestroy();
if (overlayedButton != null) {
wm.removeView(overlayedButton);
wm.removeView(topLeftView);
overlayedButton = null;
topLeftView = null;
}
}
#Override
public boolean onTouch(View v, MotionEvent event) {
if (event.getAction() == MotionEvent.ACTION_DOWN) {
float x = event.getRawX();
float y = event.getRawY();
moving = false;
int[] location = new int[2];
overlayedButton.getLocationOnScreen(location);
originalXPos = location[0];
originalYPos = location[1];
offsetX = originalXPos - x;
offsetY = originalYPos - y;
} else if (event.getAction() == MotionEvent.ACTION_MOVE) {
int[] topLeftLocationOnScreen = new int[2];
topLeftView.getLocationOnScreen(topLeftLocationOnScreen);
System.out.println("topLeftY="+topLeftLocationOnScreen[1]);

if (Math.abs(newX - originalXPos) < 1 && Math.abs(newY - originalYPos) < 1 && !moving) {
return false;
}
params.x = newX - (topLeftLocationOnScreen[0]);
params.y = newY - (topLeftLocationOnScreen[1]);
wm.updateViewLayout(overlayedButton, params);
moving = true;
} else if (event.getAction() == MotionEvent.ACTION_UP) {
if (moving) {
return true;
}
}
return false;
}
#Override

Toast.makeText(this, "Here I want to show a layout with some options in a box", Toast.LENGTH_SHORT).show();
}
}

Send a broadcast when then the button is clicked and start activity from Broadcast receivers onReceive method.
Create a broadcast receiver,Register a Broadcast reciever onCreate() of your service then. Broadcast intent when the button is clicked. Finally the receiver will open a Activity(layout) when the overlay button is clicked.
If you only wanted to open a dialog this is a decent answer. https://stackoverflow.com/a/31221355/4179914
Turns out you can also theme a activity like a dialog as mentioned here
https://stackoverflow.com/a/7918720/4179914
public class OverlayClickReceiver extends BroadcastReceiver {
#Override
public void onReceive(Context context, Intent intent) {
Intent toDialog = new Intent(context, Main2Activity.class);
toDialog.setFlags(FLAG_ACTIVITY_NEW_TASK);
context.startActivity(toDialog);
}
}
Send Broadcast on overlay button clicked.
#Override
public void onClick(View v) {
broadcastClick();
}
private void broadcastClick() {
final Intent intent = new Intent("user.clicked.overlay.button");
final LocalBroadcastManager broadcastManager = LocalBroadcastManager.getInstance(this);
broadcastManager.sendBroadcast(intent);
}
Register Broadcast receiver onCreate()
#Override
public void onCreate() {
super.onCreate();
overlayShowing = new OverlayClickReceiver();
.......
}
private void registerClickReceiver() {
LocalBroadcastManager.getInstance(this).registerReceiver(overlayShowing,
new IntentFilter("user.clicked.overlay.button"));
}
Unregister Broadcast receiver onDestroy()
#Override
public void onDestroy() {
super.onDestroy();
..........
unregisterClickReceriver();
}
private void unregisterClickReceriver() {
LocalBroadcastManager.getInstance(this).unregisterReceiver(overlayShowing);
}

From what i understood from the question, you want to get a view form xml files and add it to a window.
You can use View view = LayoutInflater.from(context).inflate(r.layout.overlay,null,false); and add that view with WindowManager.addView(view) to the window.

I couldn't add onBackPressed or a onKeyEvent methods inside the service. Please suggest a workaround. TIA

You should handle your view only from activity and use communication components such service binding or broadcasts. You shouldn't create views from service, its not appropriate.

Issue is with Listview creation. Currnetly everytime AsynTask is created it is creating the new list view. just create your list view outside of asynctask and global to class so that you can access this listview object within asyncTask like below
private ListView listView;
initialige this listView in your relevant location like below.
listView = new ListView(getApplicationContext());
listView.setAlpha(0.0f);
listView.setBackgroundColor(0x55fe4444);
adapter = new ArrayAdapter<String>(getApplicationContext(), android.R.layout.simple_list_item_1, list);
listView.setAdapter(adapter);
WindowManager.LayoutParams params = new WindowManager.LayoutParams(WindowManager.LayoutParams.WRAP_CONTENT, WindowManager.LayoutParams.WRAP_CONTENT, WindowManager.LayoutParams.TYPE_SYSTEM_ALERT, WindowManager.LayoutParams.FLAG_NOT_TOUCHABLE, PixelFormat.TRANSLUCENT);
params.gravity = Gravity.LEFT | Gravity.TOP;
params.x = 0;
params.y = 0;
wm.addView(listView, params);
In your onPostExcute of your asyncTask update your adaper for any list data change like below
adapter.notifyDataSetChanged();
