系统报错：资源无法调用释放。广播接收器。

该错误通常是由于未正确释放注册的广播接收器导致的。可以在Activity或Fragment的onDestroy（）方法中注销已注册的广播接收器，以避免此问题。

示例代码：

public class MyFragment extends Fragment { private BroadcastReceiver myReceiver; private IntentFilter intentFilter;

@Override 
public void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    myReceiver = new MyReceiver(); 
    intentFilter = new IntentFilter(); 
    intentFilter.addAction(Intent.ACTION_POWER_CONNECTED); 
    intentFilter.addAction(Intent.ACTION_POWER_DISCONNECTED); 
} 

@Override 
public void onResume() { 
    super.onResume(); 
    getActivity().registerReceiver(myReceiver, intentFilter); 
} 

@Override 
public void onPause() { 
    super.onPause(); 
    getActivity().unregisterReceiver(myReceiver); 
} 

private class MyReceiver extends BroadcastReceiver { 
    @Override 
    public void onReceive(Context context, Intent intent) { 
        String action = intent.getAction(); 
        if (action.equals(Intent.ACTION_POWER_CONNECTED)) { 
            // Do something 
        } else if (action.equals(Intent.ACTION_POWER_DISCONNECTED)) { 
            // Do something 
        } 
    } 
} 

}
