In my Application i need to Start after Reboot all the Alarms that i have set befor by using the dates in my Arraylist class that i have saved by sharedprefs. But only the one is set by the Alarmmanager. I used a BroadcastReciver and a for loop.
ArrayList<DateList1> dateses;
Date dateFromLog;
#Override
public void onReceive(Context context, Intent intent) {
SharedPreferences sharedPreferences = context.getSharedPreferences("The Selected date", MODE_PRIVATE);
Gson gson = new Gson();
String json = sharedPreferences.getString("Date0list", null);
Type type = new TypeToken<ArrayList<DateList1>>() {
}.getType();
dateses = gson.fromJson(json, type);
if (dateses == null) {
dateses = new ArrayList<>();
}
AlarmManager alarmManager = (AlarmManager) context.getSystemService(Context.ALARM_SERVICE);
ArrayList<PendingIntent> intentArray = new ArrayList<PendingIntent>();
Calendar calendar = Calendar.getInstance();
for (int i = 0; i<dateses.size(); i++){
calendar.setTime(dateses.get(i).getDate1());
Intent intent1 = new Intent(context, AlarmReceiver.class);
PendingIntent pendingIntent = PendingIntent.getBroadcast(context, i, intent1, PendingIntent.FLAG_ONE_SHOT);
alarmManager.setExact(AlarmManager.RTC_WAKEUP,calendar.getTimeInMillis(),pendingIntent);
intentArray.add(pendingIntent);
}
}
}
And here is how i add the Date to the Arraylist
ArrayList<DateList1> Dates = new ArrayList<>();
#Override
protected void onCreate(Bundle saveInstanceState) {
super.onCreate(saveInstanceState);
setContentView(R.layout.data_picker);
einfüGGen = (Button) findViewById(R.id.button3);
datums = (EditText) findViewById(R.id.datums);
fachs = (EditText) findViewById(R.id.fachs);
themens = (EditText) findViewById(R.id.themens);
GG = (TextView) findViewById((R.id.textView));
einfüGGen.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Intent resultIntent = new Intent();
resultIntent.putExtra("datum", datums.getText().toString());
resultIntent.putExtra("fach", fachs.getText().toString());
resultIntent.putExtra("themen", themens.getText().toString());
setResult(RESULT_OK, resultIntent);
finish();
int y = Dates.size();
for (int i = 0; i<Dates.size(); i++){
Toast.makeText(EingabeFeld.this,"SOOOOSSS"+y,Toast.LENGTH_LONG).show();
}
}
});
mDateSetListener = new DatePickerDialog.OnDateSetListener() {
#Override
public void onDateSet(DatePicker view, int year, int month, int dayOfMonth) {
Toast.makeText(EingabeFeld.this, "Die Erinnerung wurde festgelegt für den "+dayOfMonth+"/"+month+"/"+year, Toast.LENGTH_SHORT).show();
Calendar c = Calendar.getInstance();
c.set(year,month,dayOfMonth);
c.set(Calendar.HOUR_OF_DAY,15);
c.set(Calendar.MINUTE,20);
c.set(Calendar.SECOND,0);
Date date = c.getTime();
Dates.add(1,new DateList1(date));
startAlarm(c);
saveData();
Here is the actual class for the arraylist
public Date date1;
public DateList1(Date date){
date1 = date;
}
public Date getDate1() {
return date1;
}
}
I Hope this is going to see Someone and Thanks in Advance
I have Solved it :D.
I did the adding to the ArrayList and the saving part in my MainActivity,and got the long by the startActivityForResult Method to my MainActivity from my SecondActivity.
Thanks for those who tried to help me,i really like you guys and have a nice day with errorless Code ;D

I'm making Alarm Application for Android. I wanna set more alarms using AlarmManager. How can I do it? As far as I know, I need to use PendingIntent with different request code to set some alarms. I was trying to increment a static variable and I did it but if user reload the application the variable has request code as zero. How can I set some alarms even after a reloading my application?
I have one activity
public class NewAlarmActivity extends AppCompatActivity {
private Calendar calendar;
private static int REQUEST_CODE_ALARM = 0;
#Override
protected void onCreate(#Nullable Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_new_alarm);
showTimePickerDialog();
FloatingActionButton floatingActionButton = findViewById(R.id.fb_save_alarm);
floatingActionButton.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
saveAlarm();
}
});
}
// set time for an alarm
private void showTimePickerDialog() {
calendar = Calendar.getInstance();
TimePickerDialog timePickerDialog = new TimePickerDialog(NewAlarmActivity.this, AlertDialog.THEME_DEVICE_DEFAULT_DARK, new TimePickerDialog.OnTimeSetListener() {
#Override
public void onTimeSet(TimePicker view, int hourOfDay, int minute) {
calendar.set(Calendar.HOUR_OF_DAY, hourOfDay);
calendar.set(Calendar.MINUTE, minute);
}
}, Calendar.HOUR_OF_DAY, Calendar.MINUTE, true);
timePickerDialog.setOnCancelListener(new DialogInterface.OnCancelListener() {
#Override
public void onCancel(DialogInterface dialog) {
finish();
}
});
timePickerDialog.show();
}
// get full time like a '05:45'
private String getFullTime(int hour, int minute) {
String h = String.valueOf(hour);
String m = String.valueOf(minute);
if (hour < 10) h = "0" + hour;
if (minute < 10) m = "0" + minute;
return h + ":" + m;
}
private void saveAlarm() {
setAlarm();
insertIntoSQLite();
finish();
}
private void setAlarm() {
Intent intent = new Intent(NewAlarmActivity.this, AlarmReceiver.class);
intent.addFlags(Intent.FLAG_INCLUDE_STOPPED_PACKAGES);
PendingIntent pendingIntent = PendingIntent.getBroadcast(getApplicationContext(), ++REQUEST_CODE_ALARM, intent, PendingIntent.FLAG_UPDATE_CURRENT);
AlarmManager alarmManager = (AlarmManager) getSystemService(Context.ALARM_SERVICE);
if (alarmManager != null) {
alarmManager.set(AlarmManager.RTC_WAKEUP, calendar.getTimeInMillis(), pendingIntent);
}
}
private void insertIntoSQLite() {
DBHelper dbHelper = new DBHelper(NewAlarmActivity.this);
SQLiteDatabase database = dbHelper.getWritableDatabase();
ContentValues contentValues = new ContentValues();
contentValues.put("time", getFullTime(calendar.get(Calendar.HOUR_OF_DAY), calendar.get(Calendar.MINUTE)));
contentValues.put("description", et_description.getText().toString());
database.insert("alarm", null, contentValues);
dbHelper.close();
}
}
You can save small data to sharedPreference.
To save your REQUEST_CODE_ALARM value do this
SharedPreferences.Editor editor = getSharedPreferences(MY_PREFS_NAME, MODE_PRIVATE).edit();
editor.putInt("Request_code", REQUEST_CODE_ALARM);
editor.apply()
To retrieve it
SharedPreferences prefs = getSharedPreferences(MY_PREFS_NAME, MODE_PRIVATE);
int Request_code = prefs.getInt("REQUEST_CODE_ALARM", 0); //0 is the default value.
I dont suggest you to use SQL database for this purpose because SharedPreferences are useful for storing user preferences, where there are just a handful of variables that need storing. SQLite on the other hand would be better for storing data where there is a large set of items, such as song titles in a music library which need to be searched through.
Alarm manager will not be exact above api 19.
Try using Workmanager.
In my application I want show Toast in Desired date. For this I know I should use AlarmManager.
And for this AlarmManager I find source code from internet.
In this source give time from user with time picker but I want get time static.
I want show Toast in below date :
Date : 2017-10-26
Time : 06:49:59
MainActivity codes:
public class MainActivity extends AppCompatActivity {
//the timepicker object
TimePicker timePicker;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
//getting the timepicker object
timePicker = (TimePicker) findViewById(R.id.timePicker);
//attaching clicklistener on button
findViewById(R.id.buttonAlarm).setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
//We need a calendar object to get the specified time in millis
//as the alarm manager method takes time in millis to setup the alarm
Calendar calendar = Calendar.getInstance();
if (android.os.Build.VERSION.SDK_INT >= 23) {
calendar.set(calendar.get(Calendar.YEAR), calendar.get(Calendar.MONTH), calendar.get(Calendar.DAY_OF_MONTH),
timePicker.getHour(), timePicker.getMinute(), 0);
} else {
calendar.set(calendar.get(Calendar.YEAR), calendar.get(Calendar.MONTH), calendar.get(Calendar.DAY_OF_MONTH),
timePicker.getCurrentHour(), timePicker.getCurrentMinute(), 0);
}
setAlarm(calendar.getTimeInMillis());
}
});
}
private void setAlarm(long time) {
//getting the alarm manager
AlarmManager am = (AlarmManager) getSystemService(Context.ALARM_SERVICE);
//creating a new intent specifying the broadcast receiver
Intent i = new Intent(this, MyAlarm.class);
//creating a pending intent using the intent
PendingIntent pi = PendingIntent.getBroadcast(this, 0, i, 0);
//setting the repeating alarm that will be fired every day
am.setRepeating(AlarmManager.RTC, time, AlarmManager.INTERVAL_DAY, pi);
Toast.makeText(this, "Alarm is set", Toast.LENGTH_SHORT).show();
}
}
Broadcast codes:
public class MyAlarm extends BroadcastReceiver {
//the method will be fired when the alarm is triggerred
#Override
public void onReceive(Context context, Intent intent) {
//you can check the log that it is fired
//Here we are actually not doing anything
//but you can do any task here that you want to be done at a specific time everyday
Toast.makeText(context, "Alarm just fired", Toast.LENGTH_SHORT).show();
}
}
How can I it? I am amateur, please help me <3
Create a date with your choice and pass it to your method setAlarm()
findViewById(R.id.buttonAlarm).setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
SimpleDateFormat sdf = new SimpleDateFormat("dd-M-yyyy hh:mm:ss");
String dateInString = "26-10-2017 06:49:59";
long alarmDate = 0L;
try {
Date d = sdf.parse(dateInString);
alarmDate = d.getTime();
} catch (ParseException e) {
e.printStackTrace();
}
}
Try this code
new TimePickerDialog(this, new TimePickerDialog.OnTimeSetListener() {
#Override
public void onTimeSet(TimePicker view, int hourOfDay, int minutes) {
Calendar calendar = Calendar.getInstance();
calendar.set(Calendar.HOUR_OF_DAY, hourOfDay);
calendar.set(Calendar.MINUTE, minutes);
setAlarm(calendar.getTimeInMillis());
}
}, hr1, min1, false).show();
public class MainActivity extends AppCompatActivity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Calendar calendar = new GregorianCalendar(2017, 10, 26, 6, 49, 59);
setAlarm(calendar.getTimeInMillis());
}
private void setAlarm(long time) {
//getting the alarm manager
AlarmManager am = (AlarmManager) getSystemService(Context.ALARM_SERVICE);
//creating a new intent specifying the broadcast receiver
Intent i = new Intent(this, MyAlarm.class);
//creating a pending intent using the intent
PendingIntent pi = PendingIntent.getBroadcast(this, 0, i, 0);
//setting the alarm that will be fired once
am.set(AlarmManager.RTC, time, pi);
Toast.makeText(this, "Alarm is set", Toast.LENGTH_SHORT).show();
}
}

I have a problem with my code. i first create an alarm with a notification,Then I set the alarm for the following times - 6AM, 12PM and 6PM.

Please help me to solve my problem, thx
I'm very new to Android Studio and I am building a simple countdown timer app. I have 2 activities. The first activity(Login) the user picks a date through date picker, the second activity(Profile) shows a countdown timer. The countdown timer works perfectly when I set a date for it in the java class, but i'm having trouble trying to retrieve the date from the login activity. My code for both activities is below.
I know I have to alter the Date futureDate = dateFormat.parse("2016-8-10"); but I'm not sure how.

Note :
The Date constructor accepts the time as long in milliseconds, not seconds. You need to multiply it by 1000 and make sure that you supply it as long.
conversion
Date d = new Date(1220227200L * 1000);
Try using the putExtras() method to pass it through the Intent in a Bundle.
The following code will help out:
Sending Data through Bundle
Intent i = new Intent(this, ActivityTwo.class);
Bundle bundle = new Bundle();
bundle.putExtras("Date",YOUR_DATE);
i.putExtras(bundle);
startActivity(i);
Getting Data in new Activity
Bundle bundle = getIntent().getExtras();
String date = bundle.getString(“Date”);
This will help

Pass the values by
intent .putExtra("test", "ValueReceived");
and then in onReceive() get the value by
intent.getStringExtra("test")
Try with
OnTimeSetListener ontime = new OnTimeSetListener()
{
public void onTimeSet(TimePicker view, int hourOfDay, int minute) {
// TODO Auto-generated method stub
txt_time.setText(String.valueOf(hourOfDay) + ":" + String.valueOf(minute));
Intent intent = new Intent(getActivity(), AlarmReceiver.class);
intent.putExtra("time_value",String.valueOf(hourOfDay) + " : " + String.valueOf(minute));
PendingIntent pendingIntent = PendingIntent.getBroadcast(getActivity(), RQS_1, intent, 0);
AlarmManager alarmManager = (AlarmManager)ctx.getSystemService(Context.ALARM_SERVICE);
alarmManager.set(AlarmManager.RTC_WAKEUP, txt_time.getTimeInMillis(), pendingIntent);
}
};
You need to convert the selected time in long value (milliseconds)
use the below code to do this.
Calendar calendar = Calendar.getInstance();
calendar.set(Calendar.HOUR, hourOfDay);
calendar.set(Calendar.MINUTE, minute);
calendar.set(Calendar.AM_PM, Calendar.PM); // set AM or PM
long timeInMillis = calendar.getTimeInMillis();
and then pass this value timeInMillis in
alarmManager.set(AlarmManager.RTC_WAKEUP, timeInMillis, pendingIntent);
