即使应用程序已关闭(已终止),或者即使用户未启动应用程序,我也希望服务正在运行。我希望在安装应用程序后启动该服务,从这一点来说,该服务需要每十分钟运行一次。
虽然我找到了一些解决方案,例如
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Receiver Class ..
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>
我在主要活动中添加了以下代码。
Intent service = new Intent(getApplicationContext(), MyService.class);
this.startService(service);

Android OS将在您安装申请表格游戏商店时通知。
1。在清单文件中添加接收器,该文件将通知您用户已安装应用程序:
<receiver android:name="com.mypackagename.Installreceiver" android:exported="true">
<intent-filter>
<action android:name="com.android.vending.INSTALL_REFERRER" />
</intent-filter>
</receiver>
2。启动服务将从Installreceiver
广播接收器每10分钟继续运行。
public class Installreceiver extends BroadcastReceiver{
@Override
public void onReceive(Context context, Intent intent) {
context.startService(new Intent(context.getApplicationContext(), YourService.class));
}
}
YourService.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;
}
}
更新1:
3。如果操作系统终止您的服务,那么您需要通过另一个接收器重新开始。
在服务中添加以下两种方法:
@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
中添加接收器。
<receiver android:name=".RestartServiceReceiver" >
<intent-filter>
<action android:name="IWillStartAuto" >
</action>
</intent-filter>
</receiver>
5. 添加接收器:
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。在清单中添加权限。
<uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED" />
7. 在清单中添加接收器。
<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));
}
}
希望这会对你有所帮助。

嗯,你已经在你的问题中得到了答案,你只需要尝试那些答案。 如果你仍然无法做到,那么在这里发布您的代码。这就是Stack溢出的工作原理。
FYI使用
AlarmManager
