Android 启动时的启动警报不起作用
我已经创建了一个BroadcastReceiver，在那里我启动了3个警报和3个通知，但我尝试了我的代码，但它不工作，警报没有启动。 我还尝试将通知代码包括在if条件中，但当通知启动时，应用程序崩溃。 这是我的广播接收器代码：Android 启动时的启动警报不起作用,android,broadcastreceiver,android-notifications,Android,Broadcastreceiver,Android Notifications,我已经创建了一个BroadcastReceiver，在那里我启动了3个警报和3个通知，但我尝试了我的代码，但它不工作，警报没有启动。 我还尝试将通知代码包括在if条件中，但当通知启动时，应用程序崩溃。 这是我的广播接收器代码： @Override public void onReceive(Context context, Intent intent) { if (intent.getAction().equals(Intent.ACTION_BOOT_COM

你登记了你的接受者了吗？请参阅以下链接：。Quoted：您可以使用Context.registerReceiver动态注册此类的实例，也可以通过AndroidManifest.xml中的标记静态发布实现。也许你可以发布你的AndroidManifest.xmlaswell@DonMushroom谢谢你的回复，我已经发布了我的清单代码似乎是正确的。如果您可以在应用程序崩溃后包含包含错误消息的日志猫，将非常有用。如果你能以一种更易读的方式格式化你的代码，那么也会更容易发现你的问题@Don蘑菇还发布日志：引导接收器是否返回意图数据？关键数据是否来自引导接收器？我不这么认为。请你看那条线。String keyid=intent.getStringExtraNumberTank的回复David，你为什么说intent没有带有密钥号的ann extra，我使用：myIntent.putetraNumber，n；在setAlarm方法中，是否不正确？在启动完成时调用MyReceiver。这个意图不会有额外的数字。我明白，但我怎么能在BOOT_COMPLETE Intent上加一个额外的数字呢？你不能。当系统启动时，Android会广播这个意图。该意图由在其清单中注册的所有广播接收者接收。如果您在引导完成时需要一些信息，您应该将这些信息存储在应用程序的共享首选项中。然后，当您收到引导完成意图时，您可以查看共享首选项并检索必要的数据。我希望这是清楚的。
