Exoplayer kann nicht aus dem Speicher freigegeben werden

Question

Ich verwende Exoplayer in der Recyclerivew. Ich möchte die Exoplayer auf Activity zerstören lassen. Ich verwende Exoplayer in der ViewHolder. Ich bin nicht in der Lage, eine Möglichkeit zu finden, die Exoplayer freizugeben.

public void releaseMemory() { 
    audioCapabilitiesReceiver.unregister();//Method in the ViewHolder 
    player.release(); 
} 


public void releaseMemory() { 
    viewHolder.releaseMemory();//Method in the Adapter 
} 


@Override 
protected void onDestroy() { 
    videoAdapter.releaseMemory();//Method in the Activity 
    super.onDestroy(); 
} 

Jetzt bekomme ich die RuntimeException .ist es andere effiziente Art und Weise, dies zu tun.

Answer 1

Sie können die player onStop() - Methode für eine Aktivität stoppen stattdessen onDestroy();
