java – 如何在android中的设备启动时启动服务？

参见英文答案 > Auto start application after boot completed in Android                                    5个
我正在创建一个应用程序,它需要一直运行的服务,即使应用程序关闭,从设备启动到设备关闭.这可以在android中完成吗？

解决方法:

>首先,您需要获得许可

<uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED" />

>然后创建一个广播接收器

import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;

public class Startup extends BroadcastReceiver {

    public Startup() {
    }

    @Override
    public void onReceive(Context context, Intent intent) {
        // start your service here
        context.startService(new Intent(context, SERVICE.class));
    }

}

>在清单中注册此BroadCast Receiver

<receiver android:name="YOUR_PACKAGE.Startup" >
    <!-- This intent filter receives the boot completed event -->
    <intent-filter>
        <action android:name="android.intent.action.BOOT_COMPLETED" />
    </intent-filter>
</receiver>

Note: A service too is not guaranteed to run from device boot to device
shut down, as in extreme cases the Android system may kill the service
also to gain additional memory.
