Estoy tratando de iniciar un servicio que añade un elemento a RecyclerView cada 24 horas (todos los días). He utilizado este código, pero no funciona:
BackgroundService.java
public class BackgroundService extends Service {
private boolean isRunning;
private Context context;
private Thread backgroundThread;
SharedPreferences pref;
String isMorningChecked;
String isEveningChecked;
String isNightChecked;
String isEchuraistChecked;
String isConfessChecked;
String isBibleChecked;
String Date;
@Nullable
@Override
public IBinder onBind(Intent intent) {
return null;
}
@Override
public void onCreate() {
super.onCreate();
this.context = this;
this.isRunning = false;
this.backgroundThread = new Thread(addNewNote);
}
private Runnable addNewNote = new Runnable() {
@Override
public void run() {
Log.e("isRunning", "Yeeeeeeeeeees!");
pref = getApplicationContext().getSharedPreferences("checkStates", 0);
String checkMorningState = pref.getString("morning", "False");
String checkEveningState = pref.getString("evening", "False");
String checkNightState = pref.getString("night", "False");
String checkEchuraistState = pref.getString("echuraist", "False");
String checkConfessState = pref.getString("confess", "False");
String checkBibleState = pref.getString("bible", "False");
String writeYourNotes = pref.getString("writeNotes", "");
SimpleDateFormat sdf = new SimpleDateFormat("E", new Locale("ar"));
final SimpleDateFormat sdf2 = new SimpleDateFormat("yyyy.MM.dd");
final Timestamp timestamp = new Timestamp(System.currentTimeMillis());
Date = sdf2.format(timestamp).toString();
if(checkMorningState.equals("True")){
isMorningChecked = "+";
}else{
isMorningChecked = "-";
}
if(checkEveningState.equals("True")){
isEveningChecked = "+";
}else{
isEveningChecked = "-";
}
if(checkNightState.equals("True")){
isNightChecked = "+";
}else{
isNightChecked = "-";
}
if(checkEchuraistState.equals("True")){
isEchuraistChecked = "+";
}else{
isEchuraistChecked = "-";
}
if(checkConfessState.equals("True")){
isConfessChecked = "+";
}else{
isConfessChecked = "-";
}
if(checkBibleState.equals("True")){
isBibleChecked = "+";
}else{
isBibleChecked = "-";
}
AppDatabase db = Room.databaseBuilder(getApplicationContext(), AppDatabase.class, "Note").allowMainThreadQueries().build();
db.userDao().insertAll(new Note(sdf.format(timestamp), sdf2.format(timestamp).toString(), isMorningChecked, isEveningChecked, isNightChecked, isEchuraistChecked, isConfessChecked, isBibleChecked, writeYourNotes));
stopSelf();
}
};
@Override
public void onDestroy() {
super.onDestroy();
this.isRunning = false;
}
@Override
public int onStartCommand(Intent intent, int flags, int startId) {
if(!this.isRunning){
this.isRunning = true;
this.backgroundThread.start();
}
return START_STICKY;
}
}
BoardCastReceiver.java
public class AlarmReceiver extends BroadcastReceiver {
@Override
public void onReceive(Context context, Intent intent) {
context.startService(new Intent(context, BackgroundService.class));
}
}
Home.java
Intent alarm = new Intent(this, AlarmReceiver.class);
boolean alarmRunning = ((PendingIntent.getBroadcast(this,0,alarm,PendingIntent.FLAG_NO_CREATE)) != null);
if(alarmRunning == false){
PendingIntent pendingIntent = PendingIntent.getBroadcast(this,0,alarm,0);
AlarmManager alarmManager = (AlarmManager) getSystemService(Context.ALARM_SERVICE);
alarmManager.setRepeating(AlarmManager.ELAPSED_REALTIME_WAKEUP, SystemClock.elapsedRealtime(), 1000, pendingIntent);
He intentado esto, pero el servicio funciona una vez o dos veces y luego se detiene y, a veces me da el siguiente error:
java.lang.IllegalStateException: no se les permite empezar Intención de servicios
Usman la Victoria:
servicio en segundo plano no se puede utilizar para tareas de larga ejecución en Android 8.0 en adelante. Por favor, use JobScheduler API o WorkManager para lograr los resultados deseados. Consulte el siguiente enlace para más detalles.
