Ich habe einen Dienst in einer for ever-Schleife, aber irgendwie im Laufe der Zeit stirbt es entweder oder die Schleife endet. Ich bin schon eine Weile dabei, jede Beratung oder Vorschläge wären sehr dankbar. Danke!
So wird der Dienst gestartet
Intent myIntent = new Intent(this, MyService.class);
pendingIntent = PendingIntent.getService(this, 0, myIntent, 0);
AlarmManager alarmManager = (AlarmManager)getSystemService(ALARM_SERVICE);
Calendar calendar = Calendar.getInstance();
calendar.setTimeInMillis(System.currentTimeMillis());
calendar.add(Calendar.SECOND, 10);
alarmManager.set(AlarmManager.RTC_WAKEUP, calendar.getTimeInMillis(), pendingIntent);Und hier ist der Onstart-Befehl für den Dienst
@Override
public int onStartCommand(Intent intent, int flags, int startId)
{
try{
//Toast.makeText(getApplicationContext(), " Service Started", Toast.LENGTH_LONG).show();
@SuppressWarnings({ "rawtypes", "unchecked" })
AsyncTask<Void, Void, Void> asyncTask = new AsyncTask() {
@Override
protected void onPreExecute() {
}
@Override
protected Void doInBackground(Object... objects) {
//Get Username from sql not static value. Static value could die.
String Username = "";
SQLiteDatabase db;
db = openOrCreateDatabase(".db",SQLiteDatabase.CREATE_IF_NECESSARY,null);
db.setVersion(1);
db.setLocale(Locale.getDefault());
db.setLockingEnabled(true);
Cursor cur =db.query("userdata", null, null, null, null, null, null);
cur.moveToFirst();
while(cur.isAfterLast()==false){
Username = (cur.getString(cur.getColumnIndex("username")));
cur.moveToNext();
}
cur.close();
db.close();
int messagecount = -1;
//START MAIN LOOP TO CHECK NEW MESSAGES
/*
* Counts starts at -1 then gets count then if 1 is
* added to newcount newcount is > than last message count
* notify uesers.
*/
for(;;){
try{
String result = "";
//Shownotify();//WILL LOOP ALL THE TIME: LOOP TEST
