I created a Broadcast Receiver Which is inside the Service Class (Because of the Android Broadcast receiver restrictions Broadcast receiver stops after while, So I created Background Service, with foreground Service Notification Restriction in Android Oreo=< ). This Broadcast Receiver Listens to Phone Call States Changes IDLE, OFFHOOK, RINGING. According to the Phone call states changes(If the call ends), I get the last call details in the Cursor and Send to that details into the Firebase Realtime Database. everything works perfectly until I comment(//) on the saveDatafromCursor() method Which is inside the PhoneStateListener Class. (I write a Toast message before saving data method). it works very fine. and my service works very well. but if I uncomment my saveDatafromCursor() method After the call ended. My Service stops(notification icon and toast messages stop. I checked in the real device). Without implementing the Service, I send data to the Firebase it's working very well, Why My service stops if I try to save data to the firebase?
