android.permission.RECEIVE_BOOT_COMPLETED不会在开机启动活动 [英] android.permission.RECEIVE_BOOT_COMPLETED does not launch activity at boot

问题描述

我有我试图用项值使用 BootU preceiver 类发动活动当设备启动。问题是 - 它似乎并没有这样做，当我启动应用程序，然后重新启动设备。

I have a BootUpReceiver class which I'm attempting to use with RECEIVE_BOOT_COMPLETED to launch an Activity when the device boots. The problem is - it does not seem to do so when I launch the app then restart the device.

我已经验证没有运行Activity1.java没有问题 - 这个问题在清单或 BootU preceiver 类要么谎言，但我不知道到底为什么它不会重新启动后推出。

I have verified there is no issue running Activity1.java - the issue lies either in the Manifest or the BootUpReceiver class but I'm not sure exactly why it will not launch after rebooting.

public class BootUpReceiver extends BroadcastReceiver{


 @Override
 public void onReceive(Context context, Intent intent) {

     Intent i = new Intent(context, Activity1.class); 
            i.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
            context.startActivity(i); 

 }
}

推荐答案

删除的android：权限=android.permission.RECEIVE_BOOT_COMPLETED键，然后重试。

除此之外，还有就是你的活动出现，可能在同一时间启动任何其他活动，面前如主屏幕没有任何要求。

Beyond that, there is no requirement that your activity appear in front of any other activity that might be started around the same time, such as the home screen.
