我希望即使应用程序关闭(kiiled)或者即使用户不启动应用程序,该服务也能运行。我希望在安装应用程序后启动服务,从这一点开始,服务应该始终运行。
public class notifications extends Service {
@Override
public IBinder onBind(Intent intent) {
// TODO Auto-generated method stub
return null;
}
@Override
public void onCreate() {
}
@Override
public void onStart(Intent intent, int startId) {
final Handler handler = new Handler();
final Runnable runb = new Runnable()
{
public void run()
{
Toast.makeText(getApplicationContext(), " Service Started", Toast.LENGTH_LONG).show();
handler.postDelayed(this, 10000);
}
};
handler.postDelayed(runb, 0);
}
@Override
public void onDestroy() {
}
}*/
public class notifications extends IntentService
{
private Timer mBackGroundTimer;
public notifications()
{
super("myservice");
this.mBackGroundTimer=new Timer();
}
@Override
protected void onHandleIntent(Intent intent)
{
// TODO Auto-generated method stub
mBackGroundTimer.schedule(new TimerTask()
{
public void run()
{
try
{
Notification("This is message from Dipak Keshariya (Android Application Developer)", "This is Android Notification Message");
}
catch (Exception e)
{
// TODO Auto-generated catch block
e.printStackTrace();
}
}
},1000, 2000);
} // END onHandleIntent()
private void mStopTimer()
{
//Call this whenever you need to stop the service
mBackGroundTimer.cancel();
}
private void Notification(String notificationTitle, String notificationMessage) {
NotificationManager notificationManager = (NotificationManager) getSystemService(NOTIFICATION_SERVICE);
android.app.Notification notification = new android.app.Notification(R.drawable.ic_launcher, "A New Message from Dipak Keshariya (Android Developer)!",
System.currentTimeMillis());
Intent notificationIntent = new Intent(this, MainActivity.class);
PendingIntent pendingIntent = PendingIntent.getActivity(this, 0, notificationIntent, 0);
notification.setLatestEventInfo(getApplicationContext(), notificationTitle, notificationMessage, pendingIntent);
notificationManager.notify(10001, notification);
}
}
我怎么能这样做?
