開機自啟動Android Service,並在前台運作

編輯:Android開發教程

開機自啟動Android Service,並在前台運行

1、創建Service類

public class SeasyService extends Service{
	@Override
	public void onCreate() {
		super.onCreate();
		
		//前台Service
        NotificationCompat.Builder builder = new NotificationCompat.Builder(this);
        Notification notification = builder.build();
        startForeground(999, notification);
	}
	
	@Override
	public IBinder onBind(Intent arg0) {
		return null;
	}
	
	@Override
	public void onDestroy() {
		super.onDestroy();
		
		//停止前台Service
		stopForeground(true);
	}
}

 

2、創建廣播接收器類

public class BootBroadcastReceiver extends BroadcastReceiver {
	@Override
	public void onReceive(Context context, Intent intent) {
		String action = intent.getAction();
		
		if("android.intent.action.BOOT_COMPLETED".equals(action)){
			Intent service = new Intent(context, SeasyService.class);
			context.startService(service);
		}
	}
}

 

 

3、AndroidManifest.xml配置文件

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.example.androidservice"
    android:versionCode="1"
    android:versionName="1.0" >

    <uses-sdk
        android:minSdkVersion="18"
        android:targetSdkVersion="18" />
    
	<!-- Permission -->
    <uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED"/>

    <application
        android:allowBackup="true"
        android:icon="@drawable/ic_launcher"
        android:label="@string/app_name"
        android:theme="@style/AppTheme" >
        <activity
            android:name="com.example.service.MainActivity"
            android:label="@string/app_name" >
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />
                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
        
		<!-- Service -->
        <service 
            android:name="com.example.service.SeasyService"
            android:enabled="true" 
            android:exported="true"
            android:process=":remote">
            <intent-filter>
                <action android:name="com.example.action.SeasyService" />
            </intent-filter>
        </service>
        
		<!-- BroadcastReceiver -->
        <receiver android:name="com.example.service.BootBroadcastReceiver">
            <intent-filter>
             	<action android:name="android.intent.action.BOOT_COMPLETED"/>                 
        	</intent-filter>
        </receiver>
    </application>
</manifest>
