大佬教程收集整理的这篇文章主要介绍了BroadcastReceiver无法在我的Android应用程序中运行，大佬教程大佬觉得挺不错的，现在分享给大家，也给大家做个参考。
我有一个简单的Android应用程序,它包含一个broadcastreceiver类作为MainActivity中的内部类.代码如下.
private class MyReceiver extends BroadcastReceiver {
privatE intent receivedIntent;
@Override
public void onReceive(Context context, Intent intent) {
Log.d("mytag","onReceive function....!!!!!");
receivedIntent = intent;
}
}
根据一些标准教程,我可以在清单文件中为接收器提供静态条目.
<receiver
android:name = ".MyReceiver"
android:enabled = "true">
<intent-filter>
<action android:name = "android.intent.action.ACTION_SCREEN_OFF"/>
<action android:name = "android.intent.action.ACTION_SCREEN_ON"/>
</intent-filter>
</receiver>
但是直到我在MainActivity中添加以下行才能工作.
IntentFilter filter = new IntentFilter(Intent.ACTION_SCREEN_OFF);
filter.addAction(Intent.ACTION_SCREEN_ON);
DataWriteReceiver dataWriteReceiver = new DataWriteReceiver();
this.registerReceiver(dataWriteReceiver,filter);
即使在清单文件中输入后,我还需要执行registerReceiver吗？任何帮助表示赞赏.
但在关闭我的应用程序时,我遇到了另一个问题.
这是ADM显示的错误.

这里提到的MainActivity中的错误在registerReceiver()调用中,如下所示,
DataWriteReceiver dataWriteReceiver = new DataWriteReceiver();
this.registerReceiver(dataWriteReceiver,filter);
总结是MainActivity泄露了IntentReceiver并且我需要取消注册Receiver()吗？
请你帮帮我.
解决方法:
人们多次提出这样的问题,我刚刚搜索过这类问题,但没有一个答案向我们展示了关于此的官方答案.所以这里
