Based on some answers found in this site I adapted a code to get notifications at a certain time if someone can finalize this code and help me to activate the notifications
Screen on which to call the notification:
public class EscolhaLuzCasa extends AppCompatActivity {
private EditText rep1, rep2;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_escolha_luz_casa);
rep1 = (EditText) findViewById(R.id.horarep1);
rep2 = (EditText) findViewById(R.id.rep2);
}
public void onClick(View view ) {
Context context = null;
StartUpBootReceiver.setAlarm(context , 21, 30);
int valor = (Integer.parseInt(rep1.getText().toString()));
if(valor >= 300) {
Intent intent = new Intent(this, luzcasaalto.class);
startActivity(intent);
}else if (valor <= 200 && (valor >= 100)){
Intent intent = new Intent(this, luzcasamedio.class);
startActivity(intent);
}else if (valor < 100 ){
Intent intent = new Intent(this, luzcasabaixo.class);
startActivity(intent);
}
}
}
StartUpBootReceiver :
public class StartUpBootReceiver extends BroadcastReceiver {
private static int REPEATING_ID = 1001;
private static int ON_TIME_ID = 1002;
private static String HOUR = "hour";
private static String MINUTE = "minute";
public static void setAlarm(Context context, int hour, int minute){
SharedPreferences preferences = PreferenceManager.getDefaultSharedPreferences(context);
preferences.edit()
.putInt(HOUR, hour)
.putInt(MINUTE, minute)
.apply();
setAlarm(context);
}
@Override
public void onReceive(Context context, Intent intent) {
if (Intent.ACTION_BOOT_COMPLETED.equals(intent.getAction())) {
setAlarm(context);
Toast.makeText(context, "Alarm set", Toast.LENGTH_LONG).show();
}
}
private static void setAlarm(Context context) {
int hour = getHour(context);
int minute = getMinute(context);
if(hour == -1 || minute == -1){
//nenhum horário definido
return;
}
//Cancela possiveis alarmes existentes
cancelAlarm(context);
Calendar calendar = getCalendar(hour, minute);
//Se já passou
if(isDateBeforeNow(calendar)){
//adiciona um dia
calendar.add(Calendar.DAY_OF_MONTH, 1);
}else{
//Alarme para o horário especificado
setOneTimeAlarm(context, calendar);
//adiciona um dia para repetir o alarme no dia seguinte
calendar.add(Calendar.DAY_OF_MONTH, 1);
}
//Repete o alarme no dia seguinte
setRepeatingAlarm(context, calendar);
}
private static void setRepeatingAlarm(Context context, Calendar calendar){
PendingIntent pendingIntent = getPendingIntent(context, REPEATING_ID);
AlarmManager alarmManager = (AlarmManager)context.getSystemService(Context.ALARM_SERVICE);
//Alarme que se repete todos os dias a uma determinada hora
alarmManager.setRepeating(AlarmManager.RTC_WAKEUP,
calendar.getTimeInMillis(),
AlarmManager.INTERVAL_DAY,
pendingIntent);
}
private static void setOneTimeAlarm(Context context, Calendar calendar){
PendingIntent pendingIntent= getPendingIntent(context, ON_TIME_ID);
AlarmManager alarmManager = (AlarmManager)context.getSystemService(Context.ALARM_SERVICE);
//Alarme para o horário especificado
alarmManager.set(AlarmManager.RTC_WAKEUP,
calendar.getTimeInMillis(),
pendingIntent);
}
private static void cancelAlarm(Context context){
AlarmManager alarmManager = (AlarmManager)context.getSystemService(Context.ALARM_SERVICE);
alarmManager.cancel(getPendingIntent(context, ON_TIME_ID));
alarmManager.cancel(getPendingIntent(context, REPEATING_ID));
}
private static PendingIntent getPendingIntent(Context context, int id){
//PendingIntent para lançar o serviço
Intent serviceIntent = new Intent(context, BootService.class);
return PendingIntent.getService(context, id, serviceIntent, 0);
}
private static Calendar getCalendar(int hour, int minute){
// Cria um Calendar para o horário especificado
Calendar calendar = Calendar.getInstance();
calendar.setTimeInMillis(System.currentTimeMillis());
calendar.set(Calendar.HOUR_OF_DAY, hour);
calendar.set(Calendar.MINUTE, minute);
calendar.set(Calendar.SECOND, 0);
return calendar;
}
private static int getHour(Context context){
SharedPreferences preferences = PreferenceManager.getDefaultSharedPreferences(context);
return preferences.getInt(HOUR, -1);
}
private static int getMinute(Context context){
SharedPreferences preferences = PreferenceManager.getDefaultSharedPreferences(context);
return preferences.getInt(MINUTE, -1);
}
private static boolean isDateBeforeNow(Calendar calendar){
return calendar.getTimeInMillis() <= System.currentTimeMillis();
}
}
BootService :
public class BootService extends IntentService {
private PowerManager.WakeLock wakeLock;
public BootService() {
super("name");
}
@Override
public void onCreate() {
super.onCreate();
PowerManager pm = (PowerManager) this.getSystemService(Context.POWER_SERVICE);
wakeLock = pm.newWakeLock(PowerManager.FULL_WAKE_LOCK |
PowerManager.ACQUIRE_CAUSES_WAKEUP |
PowerManager.ON_AFTER_RELEASE, "BootService");
wakeLock.acquire();
}
@Override
protected void onHandleIntent(@Nullable Intent intent) {
NotificationCompat.Builder mBuilder = new NotificationCompat.Builder(this, "S")
.setSmallIcon(R.drawable.casa)
.setContentTitle("leklek")
.setContentText("PARABENSSSSS CARALHOOOOOOOOOOO")
.setPriority(NotificationCompat.PRIORITY_DEFAULT);
}
@Override
public void onDestroy() {
super.onDestroy();
if(wakeLock.isHeld()){
//Verificou-se que o iluminar do ecrã
//não acontecia devido ao WakeLock ser
//rapidamente libertado(apesar de PowerManager.ON_AFTER_RELEASE !?).
try {
//Atrasa a libertação do WakeLock
//de forma a permitir a iluminação do ecrâ.
Thread.sleep(5000);
} catch (InterruptedException e) {
e.printStackTrace();
}
finally {
wakeLock.release();
}
}
}
}
