要求Android服务每十分钟持续运行一次

Question

我希望即使应用程序关闭(终止)或即使用户没有启动应用程序，服务也能运行。我想在安装应用程序后启动该服务，从这一点开始，该服务需要每十分钟持续运行一次。

虽然我找到了一些解决办法比如

• Android Service needs to run always (Never pause or stop)
• Android - Run a service in background even when app is killed or device rebooted
• How to run android service permanently like system service?

这些对我不起作用，因为我是 Android 编程的新手。如果有任何示例工作源代码，请向我提供如何开发它的信息。

这是我的服务类..

public class MyService extends Service {

    MyReceiver receiver = new MyReceiver();

    public void onCreate()
    {
        super.onCreate();       
    }

    @Override
    public IBinder onBind(Intent intent) {
        // TODO Auto-generated method stub
        return null;
    }

    @Override
    public int onStartCommand(Intent intent, int flags, int startId) {
        receiver.SetAlarm(this);
        return START_STICKY;
    }

    @Override        
    public void onStart(Intent intent, int startId)
    {
        receiver.SetAlarm(this);
    }

}

这是我的接收器类..

public class MyReceiver extends BroadcastReceiver {

    @Override
    public void onReceive(Context context, Intent intent) {
        try {
            PowerManager pm = (PowerManager) context.getSystemService(Context.POWER_SERVICE);
            PowerManager.WakeLock wl = pm.newWakeLock(PowerManager.PARTIAL_WAKE_LOCK, "");
            wl.acquire();

            // Put here YOUR code.
            Toast.makeText(context, "Alarm !!!!!!!!!!", Toast.LENGTH_LONG).show(); // For example

            wl.release();
        }catch (Exception e) {
            e.printStackTrace();
        }
    }

    public void SetAlarm(Context context)
    {
        AlarmManager am =( AlarmManager)context.getSystemService(Context.ALARM_SERVICE);
        Intent i = new Intent(context, UploadLocReceiver.class);
        PendingIntent pi = PendingIntent.getBroadcast(context, 0, i, 0);
        am.setRepeating(AlarmManager.RTC_WAKEUP, System.currentTimeMillis(), 1000 * 60 * 10, pi); // Millisec * Second * Minute
    }

}

我在 AndroidManifest.xml 文件中添加了服务和接收器。

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

<service android:name=".MyService" 
            android:exported="false" >
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />
                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </service>

 <receiver android:name=".MyReceiver" >
            <intent-filter>
                <action android:name="android.net.conn.CONNECTIVITY_CHANGE" />
            </intent-filter>
        </receiver>

我在主 Activity 中添加了以下代码。

Intent service = new Intent(getApplicationContext(), MyService.class);
        this.startService(service);

Android 操作系统会在您安装应用程序时通知您。

1.在ma​​nifest文件中添加receiver，它会通知你用户已经安装了应用:

<receiver android:name="com.mypackagename.Installreceiver" android:exported="true">
      <intent-filter>
          <action android:name="com.android.vending.INSTALL_REFERRER" />
     </intent-filter>
</receiver>

2. 从 Installreceiver 广播接收器开始每 10 分钟运行一次的服务。

public class Installreceiver extends BroadcastReceiver{
       @Override
        public void onReceive(Context context, Intent intent) {
        context.startService(new Intent(context.getApplicationContext(), YourService.class));
       }
    }

你的服务.java:

public class YourService extends Service {

    private static String TAG = "MyService";
    private Handler handler;
    private Runnable runnable;
    private final int runTime = 10000;

    @Override
    public void onCreate() {
        super.onCreate();
        Log.i(TAG, "onCreate");

        handler = new Handler();
        runnable = new Runnable() {
            @Override
            public void run() {

                handler.postDelayed(runnable, runTime);
            }
        };
        handler.post(runnable);
    }

    @Override
    public IBinder onBind(Intent intent) {
        return null;
    }

    @Override
    public void onDestroy() {
        super.onDestroy();
    }

    @Override
    public int onStartCommand(Intent intent, int flags, int startId) {
        return START_STICKY;
    }
}

3.如果操作系统终止了您的服务，那么您需要通过执行另一个接收器重新开始。

在服务中添加以下两个方法:

@Override
public void onTaskRemoved(Intent rootIntent) {
   super.onTaskRemoved(rootIntent);
   sendBroadcast(new Intent("IWillStartAuto"));
}

 @Override
 public void onDestroy() {
   super.onDestroy();
   sendBroadcast(new Intent("IWillStartAuto"));
 }

4.在manifest中添加receiver。

<receiver android:name=".RestartServiceReceiver" >
     <intent-filter>
         <action android:name="IWillStartAuto" >
         </action>
      </intent-filter>
 </receiver>

5. 添加接收者:

public class RestartServiceReceiver extends BroadcastReceiver{
   @Override
    public void onReceive(Context context, Intent intent) {
    context.startService(new Intent(context.getApplicationContext(), YourService.class));
   }
}

更新 2:

6.在 list 中添加权限。

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

7.在 list 中添加接收者。

<receiver android:name=".BootCompletedReceiver" >
      <intent-filter>
             <action android:name="android.intent.action.BOOT_COMPLETED" />
             <action android:name="android.intent.action.QUICKBOOT_POWERON" />
      </intent-filter>
</receiver>

7. BootCompletedReceiver,java:

public class BootCompletedReceiver extends BroadcastReceiver {

@Override
public void onReceive(Context context, Intent arg1) {
    context.startService(new Intent(context.getApplicationContext(), YourService.class));
  }
}

希望对您有所帮助。
