设备打开时打开Android应用程序

Question

I'm developing an android application that I want that starts when the device is opened and remains on foreground until it is closed. To achieve this I have used some tricks that I found surfing the Internet:

• Start application when device starts >> Solved using a broadcast receiver that handles the android.intent.action.BOOT_COMPLETED
• Ignore the Home button when the application is opened >> Solved using an Activity Alias that is installed when the app starts and uninstalled when the application closes

I test the solution and it works fine almost always. When I close the device with the app executing and it restarts the device the application is opened twice. I think that the extra opening is due because the Activity Alias wasn't uninstalled because the app doesn't close properly when I shutdown the device.

Is there a solution to avoid this behavior?

Thanks

Answer 1

您应该使用ACTION_SHUTDOWN并在shutdown时执行必要的任务。在此处查看更多详细信息。

You can maybe use the Shutdown intent to finish your activity when the device is shutting down.

<receiver android:name=".myReceiver">
  <intent-filter>
    <action android:name="android.intent.action.ACTION_SHUTDOWN" />
  </intent-filter>
</receiver>

Then you can just use the activity.finish(); to close your app.
