我有一个每 5 分钟运行一次的 IntentService。我遇到的问题是当用户退出应用程序时，服务会启动应用程序。如何向服务指定不应启动应用程序？目前它没有达到预期的效果，因为用户可能会在应用程序启动时发短信。
我如何启动服务。
// get a Calendar object with current time
Calendar cal = Calendar.getInstance();
// add 5 minutes to the calendar object
cal.add(Calendar.MINUTE, 1);
Intent intent = new Intent(EntryActivity.this, AlarmReceiver.class);
intent.putExtra("alarm_message", "sending outstanding transactions");
// In reality, you would want to have a static variable for the request code instead of 192837
PendingIntent sender = PendingIntent.getBroadcast(EntryActivity.this, 192837, intent, PendingIntent.FLAG_UPDATE_CURRENT);
// Get the AlarmManager service
AlarmManager am = (AlarmManager) getSystemService(ALARM_SERVICE);
//am.set(AlarmManager.RTC_WAKEUP, cal.getTimeInMillis(), sender);
//43200000 = 12 hours
//3600000 = 1hr
//1800000 = 30 mins
//300000 = 5 mins
am.setRepeating(AlarmManager.RTC_WAKEUP, cal.getTimeInMillis(), 300000 , sender);

public class AlarmReceiver extends BroadcastReceiver {
@Override
public void onReceive(Context context, Intent intent) {
try {
Bundle bundle = intent.getExtras();
String message = bundle.getString("alarm_message");
// Toast.makeText(context, message, Toast.LENGTH_SHORT).show();
Intent myIntent = new Intent(context, SendOutstandingTransactions.class);
myIntent.setAction("com.carefreegroup.startatboot.MyService");
context.startService(myIntent);
} catch (Exception e) {
Toast.makeText(context, "There was an error somewhere, but we still received an alarm", Toast.LENGTH_SHORT).show();
e.printStackTrace();
}
}
}
