I am working on an App in which i want to set custom alarm.but after setting a time on alarm nothing happens. i am sharing my code. Please help and guide me if something is missing in my code.
In my MainActivity.java
#Override
protected Dialog onCreateDialog(int id) {
if (id == DIALOG_ID) {
return new TimePickerDialog(MainActivity.this, kTimePickerListener, hour, min, false);
}
return null;
}
protected TimePickerDialog.OnTimeSetListener kTimePickerListener =
new TimePickerDialog.OnTimeSetListener() {
#Override
public void onTimeSet(TimePicker timePicker, int hourofday, int minutes) {
hour = hourofday;
min = minutes;
Calendar calendar = Calendar.getInstance();
// set selected time from timepicker to calendar
calendar.set(Calendar.HOUR_OF_DAY, hour);
calendar.set(Calendar.MINUTE, minutes);
Intent myIntent = new Intent(MainActivity.this, ServiceManager.class);
myIntent.putExtra("reqcode", 11);
// A PendingIntent specifies an action to take in the
// future
PendingIntent mPendingIntent = PendingIntent.getBroadcast(MainActivity.this, 11, myIntent, 0);
// set alarm time
alarmManager = (AlarmManager) MainActivity.this
.getSystemService(Context.ALARM_SERVICE);
alarmManager.set(AlarmManager.RTC, calendar.getTimeInMillis(), mPendingIntent);
}
};
In My ServiceManager.class
public class ServiceManager extends BroadcastReceiver {
#Override
public void onReceive(Context context, Intent intent) {
int Noti_code = intent.getIntExtra("reqcode",-1);
Intent myIntent = new Intent(context, NotificationService.class);
myIntent.putExtra("reqcode", Noti_code);
context.startService(myIntent);
}
}
In My NotificationService.class
public class NotificationService extends Service {
private NotificationManager mManager;
#Override
public IBinder onBind(Intent arg0) {
// TODO Auto-generated method stub
return null;

int Noti_Code = intent.getIntExtra("reqcode",-2);
if (Noti_Code == 11) {
mManager = (NotificationManager) this.getApplicationContext().getSystemService(this.getApplicationContext().NOTIFICATION_SERVICE);
ShowNotification(getApplicationContext(), mManager);
}
}
#Override

I am checking through debugging broadcast receiver doesn't called. Please help me if i am missing any thing.
Also i want to know how many pending intent can be fire at a time and will all works one by one?
Thanks.

BroadcastReceiver and AlarmManager not working with
AlarmManager is not working after app is closed? - Android
You have your BroadcastReceiver running in another process. If you are setting breakpoints with a debugger you will miss this. If you don't need your BroadcastReceiver running in a separate process, remove the
android:process=":remote"
declaration from the manifest.
See the documentation about how the android:process specifier works.

Can anyone please correct my approach or suggest me the right ways for doing it.I have tried using broadcast receivers in place of services but that approach is not working for it.i.e I used getBroadcast() in place of getService() but didnt work.
It is working when the app is not closed from the application window but as soon as it is closed , the phone doesnt show notifications and ring as it was working in the case when the app wasn't closed.

I want start my Service after reboot device, I write below codes but when reboot device not start Service.

Activity code:
public class alarm1 extends AppCompatActivity {
private PendingIntent pendingIntent;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_alarm1);
/* Retrieve a PendingIntent that will perform a broadcast */

public void start() {
AlarmManager manager = (AlarmManager) getSystemService(Context.ALARM_SERVICE);
int interval = 8000;
manager.setInexactRepeating(AlarmManager.RTC_WAKEUP, System.currentTimeMillis(), interval, pendingIntent);

int interval = 1000 * 60 * 20;
/* Set the alarm to start at 10:30 AM */
Calendar calendar = Calendar.getInstance();
calendar.setTimeInMillis(System.currentTimeMillis());
calendar.set(Calendar.HOUR_OF_DAY, 17);
calendar.set(Calendar.MINUTE, 15);
Toast.makeText(alarm1.this, "Start at 17:11", Toast.LENGTH_SHORT).show();
/* Repeating on every 20 minutes interval */
manager.setRepeating(AlarmManager.RTC_WAKEUP, calendar.getTimeInMillis(),
1000 * 60 * 3, pendingIntent);
}
}
AlarmReceiver codes:
public class AlarmReceiver extends BroadcastReceiver {
#Override
public void onReceive(Context context, Intent intent) {
// For our recurring task, we'll just display a message
Toast.makeText(context, "I'm running", Toast.LENGTH_SHORT).show();
}
}
DeviceBootReceiver codes:
public class DeviceBootReceiver extends BroadcastReceiver {
#Override
public void onReceive(Context context, Intent intent) {
if (intent.getAction().equals("android.intent.action.BOOT_COMPLETED")) {
/* Setting the alarm here */
Intent alarmIntent = new Intent(context, AlarmReceiver.class);
PendingIntent pendingIntent = PendingIntent.getBroadcast(context, 0, alarmIntent, 0);
AlarmManager manager = (AlarmManager) context.getSystemService(Context.ALARM_SERVICE);
int interval = 8000;
manager.setInexactRepeating(AlarmManager.RTC_WAKEUP, System.currentTimeMillis(), interval, pendingIntent);
Toast.makeText(context, "Alarm Set", Toast.LENGTH_SHORT).show();
}
}
}
How can I fix this and when reboot device start Service?
Add permissions in Manifest.
<uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED" />
Add receiver entry in Manifest.
<receiver android:enabled="true" android:name=".alarm1.DeviceBootReceiver"
android:permission="android.permission.RECEIVE_BOOT_COMPLETED">
<intent-filter>
<action android:name="android.intent.action.BOOT_COMPLETED" />
<category android:name="android.intent.category.DEFAULT" />
</intent-filter>
</receiver>
You just need to
Request a permission
and
Explicitly enable the receiver.
The permission goes in the manifest file:
<uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED"/>
Then when the user sets an alarm (for example your start method), enable the boot receiver:
ComponentName receiver = new ComponentName(context, DeviceBootReceiver.class);
getPackageManager().setComponentEnabledSetting(receiver,
PackageManager.COMPONENT_ENABLED_STATE_ENABLED,
PackageManager.DONT_KILL_APP);
When the user cancels all alarms, you should disable the boot receiver using a similar piece of code.
My alarmmanager code working good. But after boot I can't reschedule my alarm. Can you please tell me where I did mistake?
As you can see in DeviceBootReciever I put the toast. But even this toast doesn't appear. It means I can't listen boot completed.
But I didn't understand the reason. Here I have mentioned my code. Any help will be appreciated!

I have created a receiver that Extends BroadcastReceiver. This is used to execute my Notification that repeats daily, based on the time selected by the user. For some reason i cant get this to work. I am worried that i am getting the time from the number pickers wrong, but i am new to programing and could use some help. Thank you in advance. Let me know if you see any Errors.
Here is my main activity (MyActivity)
public class MyActivity extends Activity {
TimePicker timePicker;
Button setAlarm;
private int hour;
private int minute;
PendingIntent pendingIntent;
int AM_PM;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_my);
timePicker = (TimePicker) findViewById(R.id.timePicker);
setAlarm = (Button) findViewById(R.id.setUpAlarm);
setAlarm.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
setAlarm();
}
});
}
private void setAlarm() {
int hour = timePicker.getCurrentHour();
int minute = timePicker.getCurrentMinute();
long time = 60 * hour + minute;
AlarmManager alarmMgr = (AlarmManager) getSystemService(ALARM_SERVICE);
Intent intent = new Intent(this, NotifyService.class);
PendingIntent alarmIntent = PendingIntent.getBroadcast(this, 0, intent, 0);
//create alarms
Calendar calendar = Calendar.getInstance();
calendar.setTimeInMillis(System.currentTimeMillis());
calendar.set(Calendar.HOUR_OF_DAY, hour);
calendar.set(Calendar.MINUTE, minute);
// AlarmManager.INTERVAL_DAY.
alarmMgr.setInexactRepeating(AlarmManager.RTC_WAKEUP, calendar.getTimeInMillis(),
AlarmManager.INTERVAL_DAY, alarmIntent);
}
Here is my Notification class ( extends BroadcatsReceiver )
public class NotifyService extends BroadcastReceiver {
public NotifyService() {
}
#Override
public void onReceive(Context context, Intent intent) {
//generate notification // should be splash activity
PendingIntent pi = PendingIntent.getActivity(context, 0, new Intent(context, MyActivity.class), 0);
Notification notification = new NotificationCompat.Builder(context)
.setContentTitle(null)
.setContentText("Your tip for today is ready")
.setSmallIcon(R.drawable.ic_launcher)
.setContentIntent(pi)
.build();
}
// dont forget to compile "com.android.support:support-v4:18.0.+"
}
Here is my manifest
<uses-permission android:name="android.permission.WAKE_LOCK"/>
<uses-permission android:name="android.permission.INTERNET" />
<application
android:allowBackup="true"
android:icon="#drawable/ic_launcher"
android:label="#string/app_name"
android:theme="#style/AppTheme" >
<activity
android:name=".MyActivity"
android:label="#string/app_name" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<receiver
android:name=".NotifyService"
android:enabled="true"
android:exported="true" >
</receiver>
</application>
Dont use a receiver with a filter in your android manifest. Create an 'explicit intent' instead of using an intent filter. This way,
Intent i = new Intent(your random intent Action name).
This should fix you problem
Why my AlarmManager for service update doesn't work? this is my code:
public class MainActivity extends ActionBarActivity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
startService();
}
// Method to start the service
public void startService() {
startService(new Intent(getBaseContext(), MyService.class));
}
// Method to stop the service
public void stopService() {
stopService(new Intent(getBaseContext(), MyService.class));
}
Service class:
public class MyService extends Service {
#Override
public IBinder onBind(Intent intent) {
// TODO Auto-generated method stub
return null;
}
#Override
public int onStartCommand(Intent intent, int flags, int startId) {
// Let it continue running until it is stopped.
Toast.makeText(this, "Service Started", Toast.LENGTH_LONG).show();
return START_STICKY;
}
#Override
public void onCreate() {
poruka();
super.onCreate();
}
public void poruka(){
Toast.makeText(this, "OnCreate work!", Toast.LENGTH_LONG).show();
}
}
BroadcastReceiver and AlarmManager:
public class ServiceBroadcast extends BroadcastReceiver {
#Override
public void onReceive(Context context, Intent intent) {
context.startService(new Intent(context, MyService.class));
Intent alarmIntent = new Intent(context, ServiceBroadcast.class);
PendingIntent pendingIntent = PendingIntent.getBroadcast(context, 0, alarmIntent, PendingIntent.FLAG_UPDATE_CURRENT);
AlarmManager alarmManager = (AlarmManager)context.getSystemService(Context.ALARM_SERVICE);
alarmManager.setRepeating(AlarmManager.RTC, Calendar.getInstance().getTimeInMillis(), 30*1000, pendingIntent);
}
}
And Permissions:
<application
android:allowBackup="true"
android:icon="#drawable/ic_launcher"
android:label="#string/app_name"
android:theme="#style/AppTheme" >
<activity
android:name="me.example.nservice.MainActivity"
android:label="#string/app_name" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<service android:name=".MyService" android:enabled="true"
android:label="Servisv1" />
<receiver android:name="me.example.rqservice.ServiceBroadcast" android:process=":remote">
<intent-filter>
<action android:name="android.intent.action.BOOT_COMPLETED" />
</intent-filter>
</receiver>
</application>
I receive message "OnCreate work!" and "Service Started" only first time when i open app. Why update doesn't work every 30 sec?
To start a service every 30 seconds :
Inside onCreate() :
Here MyService is the name of the Service.
Intent myService = new Intent(this, MyService.class);
PendingIntent pendingIntent = PendingIntent.getService(
this, 0, myService, 0);
AlarmManager alarmManager = (AlarmManager)getSystemService(Context.ALARM_SERVICE);
alarmManager.setRepeating(AlarmManager.RTC_WAKEUP,
System.currentTimeMillis(), 30*1000,pendingIntent);
This'll start your service every 30 seconds. However, if the service is already running, which might be the case once it has been started the first time, from next time onwards the call will directly go to onStartCommand() method of the Service and not onCreate().
This is all that you need to do. However, if you want to make sure that the AlarmManager keeps restarting the service even after a phone is restarted, you'll need to add a BroadcastReceiver for Boot.
