How can Android implement a boot startup service?

To enable a startup service on an Android device, you can follow these steps:

1. Create a class that extends Service to implement your backend service logic, such as a class named MyService.

public class MyService extends Service {
    // 服务逻辑的实现代码
    @Override
    public IBinder onBind(Intent intent) {
        return null;
    }

    @Override
    public int onStartCommand(Intent intent, int flags, int startId) {
        // 在这里写入你的服务逻辑
        return super.onStartCommand(intent, flags, startId);
    }
}

1. software application

<service 
    android:name=".MyService"
    android:enabled="true"
    android:exported="false" />

Make sure to use the full package name and class name of your service class as the value for android:name.

1. Create a BroadcastReceiver class to receive the boot broadcast. For example, you can create a class named BootReceiver.

public class BootReceiver extends BroadcastReceiver {
    @Override
    public void onReceive(Context context, Intent intent) {
        if (Intent.ACTION_BOOT_COMPLETED.equals(intent.getAction())) {
            // 在这里启动你的服务
            Intent serviceIntent = new Intent(context, MyService.class);
            context.startService(serviceIntent);
        }
    }
}

<receiver 
    android:name=".BootReceiver"
    android:enabled="true"
    android:exported="false">
    <intent-filter>
        <action android:name="android.intent.action.BOOT_COMPLETED" />
    </intent-filter>
</receiver>

Make sure to use the full package name and class name of your BroadcastReceiver class as the value for android:name.

After completing the above steps, when the Android device finishes booting up, the system will send an ACTION_BOOT_COMPLETED broadcast, which your broadcast receiver will receive and start your service.
