I have to implement an Overlay Window like True Caller App has.But the problem I am getting is, During any Incoming or Outgoing call my service automatically getting close or destroyed.
Service class
public class OverlayService extends Service implements View.OnClickListener,NotifyHardwareChanges,UpdateSoundDB{
private WindowManager windowManager;
WindowManager.LayoutParams params;
View view;
Button btnEndCall;
public static TextView textView;
public static Context cntxt;
@Nullable
@Override
public IBinder onBind(Intent intent) {
return null;
}
@Override
public int onStartCommand(Intent intent, int flags, int startId) {
// Let it continue running until it is stopped.
return START_NOT_STICKY;
}
@Override
public void onCreate() {
super.onCreate();
this.cntxt = getApplicationContext();
windowManager = (WindowManager) getSystemService(WINDOW_SERVICE);
params= new WindowManager.LayoutParams(
WindowManager.LayoutParams.MATCH_PARENT,
WindowManager.LayoutParams.WRAP_CONTENT,
WindowManager.LayoutParams.TYPE_PHONE,
WindowManager.LayoutParams.FLAG_NOT_FOCUSABLE,
PixelFormat.TRANSLUCENT);
params.gravity = Gravity.CENTER;
params.x = 0;
params.y = 100;
LayoutInflater inflater = (LayoutInflater) getSystemService(Context.LAYOUT_INFLATER_SERVICE);
view = inflater.inflate(R.layout.list_item, null);
textView = (TextView) view.findViewById(R.id.textView);
btnEndCall = (Button) view.findViewById(R.id.end_call);
//btnEndCall.set
btnEndCall.setOnClickListener(this);
//this code is for dragging the chat head
view.setOnTouchListener(new View.OnTouchListener() {
private int initialX;
private int initialY;
private float initialTouchX;
private float initialTouchY;
@Override
public boolean onTouch(View v, MotionEvent event) {
switch (event.getAction()) {
case MotionEvent.ACTION_DOWN:
initialX = params.x;
initialY = params.y;
initialTouchX = event.getRawX();
initialTouchY = event.getRawY();
return true;
case MotionEvent.ACTION_UP:
return true;
case MotionEvent.ACTION_MOVE:
params.x = initialX
+ (int) (event.getRawX() - initialTouchX);
params.y = initialY
+ (int) (event.getRawY() - initialTouchY);
windowManager.updateViewLayout(view, params);
return true;
}
return false;
}
});
windowManager.addView(view, params);
Utillities.start(OverlayService.this, 1, OverlayService.this);
}
@Override
public void onDestroy() {
super.onDestroy();
if (view != null)
windowManager.removeView(view);
Utillities.stop(OverlayService.this,1,OverlayService.this);
}
@Override
public void onClick(View v) {
if(view!=null){
Utillities.stop(OverlayService.this,1,OverlayService.this);
windowManager.removeView(view);
view = null;
}
}
@Override
public void getNotify(String str) {}
@Override
public void setProcess(double signalEMA) {
int progress = ((int) signalEMA - Preferences.readInteger(getApplicationContext(), Preferences.CALIBRATION, 0)) ;
textView.setText("Your Sound Level :" + progress +"db");
if ((Preferences.readInteger(cntxt, Preferences.SOUND_LEVEL, 0) > 0) && (progress > Preferences.readInteger(cntxt, Preferences.SOUND_LEVEL, 0))) {
textView.setTextColor(cntxt.getResources().getColor(R.color.red));
}else{
textView.setTextColor(cntxt.getResources().getColor(R.color.black));
}
}
}
And Here following is a BroadcastReceiver to detect the Incoming And Outgoing Call and also being used to Start and Stop Overlayservice.
public class ServiceReceiver extends BroadcastReceiver{
TelephonyManager telephonyManager;
@TargetApi(Build.VERSION_CODES.HONEYCOMB_MR2) @Override
public void onReceive(Context context, Intent intent) {
// TODO Auto-generated method stub
if(Preferences.readBoolean(context, Preferences.APP_ON_OFF, false) == true){
//The other intent tells us the phone state changed. Here we set a listener to deal with it
TelephonyManager telephony = (TelephonyManager)context.getSystemService(Context.TELEPHONY_SERVICE);
telephony.listen(new PhonecallStartEndDetector(context), PhoneStateListener.LISTEN_CALL_STATE);
}
}
public class PhonecallStartEndDetector extends PhoneStateListener {
int lastState = TelephonyManager.CALL_STATE_IDLE;
boolean isIncoming;
Context cntx;
public PhonecallStartEndDetector(Context context) {
this.cntx = context;
}
//Incoming call- goes from IDLE to RINGING when it rings, to OFFHOOK when it's answered, to IDLE when its hung up
//Outgoing call- goes from IDLE to OFFHOOK when it dials out, to IDLE when hung up
@Override
public void onCallStateChanged(int state, String incomingNumber) {
super.onCallStateChanged(state, incomingNumber);
if (lastState == state) {
//No change, debounce extras
return;
}
switch (state) {
case TelephonyManager.CALL_STATE_RINGING:
isIncoming = true;
//cntx.startService(new Intent(cntx, OverlayService.class));
//Toast.makeText(cntx, "onIncomingCallStarted", Toast.LENGTH_SHORT).show();
break;
case TelephonyManager.CALL_STATE_OFFHOOK:
//Transition of ringing->offhook are pickups of incoming calls. Nothing donw on them
if (lastState != TelephonyManager.CALL_STATE_RINGING) {
isIncoming = false;
cntx.startService(new Intent(cntx, OverlayService.class));
//Toast.makeText(cntx, "onOutgoingCallStarted", Toast.LENGTH_SHORT).show();
}else{
isIncoming = true;
cntx.startService(new Intent(cntx, OverlayService.class));
}
break;
case TelephonyManager.CALL_STATE_IDLE:
//Went to idle- this is the end of a call. What type depends on previous state(s)
if (lastState == TelephonyManager.CALL_STATE_RINGING) {
//Ring but no pickup- a miss
cntx.stopService(new Intent(cntx, OverlayService.class));
//Toast.makeText(cntx, "onMissedCall", Toast.LENGTH_SHORT).show();
} else if (isIncoming) {
cntx.stopService(new Intent(cntx, OverlayService.class));
//Toast.makeText(cntx, "onIncomingCallEnded", Toast.LENGTH_SHORT).show();
} else {
cntx.stopService(new Intent(cntx, OverlayService.class));
//Toast.makeText(cntx, "onOutgoingCallEnded", Toast.LENGTH_SHORT).show();
}
break;
}
lastState = state;
}
}
}
An overlay is one of the primary surfaces for app content. Overlays are different from complications or Tiles, which are glanceable representations of app content. Overlays display more information and support richer interactivity.
Screen overlay is a feature of modern Android smartphones and tablets that allows compatible applications to appear on top of others.
Foreground service have high priority , so try creating your service as a foreground service and check if that works. For creating a foreground service you need to provide a notification , so that users are aware that a foreground service is going on.
Here's how you can create a foreground service
But before making your service foreground , debug why your current service is getting killed by checking the logs.
