BroadcastReceiver在我的android应用程序中不工作

我有一个简单的Android应用程序，它包含一个broadcastreceiver类，作为MainActivity中的一个内部类。代码如下所示

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者设置一个静态条目

<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>

即使在清单文件中的条目之后，我也需要执行registerReceiver吗？感谢您的帮助

但在关闭我的应用程序时，我遇到了另一个问题。 这是ADM显示为错误的内容

总结是MainActivity泄漏了IntentReceiver，是否需要注销Receiver（）

你能帮我一下吗。

人们问过很多次这种问题，我刚才搜索过这种问题，但没有一个答案告诉我们关于这一点的官方答案。所以在这里

记住：Android官方文档会让您更好地了解Android，不是有时，而是几乎每次。

这里的答案可以帮助你：还有：谢谢！现在对我来说没问题，但也许我会发现安卓官方在未来不会告诉我一些事情。：-）最后一句话是为了让我记住阅读Android官方文档的重要性，是的，这不是100%：-：-：-）：-）是的，如果你应该读：

“…不是有时，但几乎每次”

，但当然，阅读官方文件是必须的，而且很多人并不关心这一点…我接受了你的判决！是的，我非常同意你的观点，我遇到了很多不关心官方文件的人。谢谢。我就是这么做的。行动现在得到承认。

DataWriteReceiver dataWriteReceiver = new DataWriteReceiver();
this.registerReceiver(dataWriteReceiver,filter);
