注意：带有android:excludeFromRecents="true"的活动标志

@Override
    protected void onDestroy() {

        sendBroadcast(new Intent("com.android.servicerestart"));
        if(broadcastReceiver != null) {
            try {
                unregisterReceiver(broadcastReceiver);
            }
            catch (IllegalArgumentException E)
            {

            }
        }

        super.onDestroy();
        Log.e("Activity","In OnDestroy");
    }

    @Override
    protected void onPause() {

        if(broadcastReceiver != null) {
            try {
                unregisterReceiver(broadcastReceiver);
            }
            catch (IllegalArgumentException E)
            {
                E.printStackTrace();
            }
        }
        super.onPause();
        Log.e("Activity","In OnPause");
    }

    @Override
    protected void onResume() {

        registerReceiver();
        super.onResume();
        Log.e("Activity","In onResume");
    }

    @Override
    protected void onStart() {
        super.onStart();
        try {
            registerReceiver();
        }
        catch (Exception E)
        {

        }
    }

registerReceiver（）;

private void registerReceiver() {
    broadcastReceiver = new BroadcastReceiver() {
        @Override
        public void onReceive(Context context, Intent intent) {

        }
    };

    try {
        registerReceiver(broadcastReceiver, new IntentFilter("*******.receive.service.download"));
    }
    catch (Exception E)
    {

    }
}

这是生命周期问题

start和resume都注册了一个接收者-但是没有检查是否已经存在一个接收者（因此您注册了两个单独的接收者）

这意味着在pause和destroy方法上只能看到第二个方法，第一个方法被泄漏。

最好的解决方法是删除启动/销毁块。否则，您可以将new BroadcastReceiver块包装在if (broadcastReceiver == null)

中

本地广播接收器异常：android.app.IntentReceiverLeaked？
