To achieve listening to the boot broadcast in Android, the first step is to create a broadcast receiver to receive the boot broadcast sent by the system. The specific steps are as follows:

  1. Create a class that extends BroadcastReceiver, which is used to receive boot-up broadcast.
public class BootReceiver extends BroadcastReceiver {
    @Override
    public void onReceive(Context context, Intent intent) {
        if (intent.getAction().equals(Intent.ACTION_BOOT_COMPLETED)) {
            // 在此处处理开机启动事件
            // 可以在这里启动需要在开机时运行的服务或应用
        }
    }
}
  1. Register the broadcast receiver in the AndroidManifest.xml file and add the necessary permissions and filters.
<receiver android:name=".BootReceiver">
    <intent-filter>
        <action android:name="android.intent.action.BOOT_COMPLETED" />
        <category android:name="android.intent.category.DEFAULT" />
    </intent-filter>
</receiver>
  1. Add permission declaration to allow the application to listen to the system boot broadcast.
<uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED" />

By following the steps above, you can achieve the ability to listen to system broadcasts when an Android device starts up and handle the corresponding logic in the broadcast receiver. It is important to note that in order to improve the stability and performance of the application, it is suggested to minimize time-consuming operations in the boot broadcast receiver and avoid affecting the system startup speed.
