package com.application.outgoingemail;
import android.app.Service;
import android.content.Intent;
import android.os.IBinder;
import android.widget.Toast;
public class EmailService extends Service {
#Override
public IBinder onBind(Intent intent) {
return null;
}
#Override
public void onCreate() {
//Toast.makeText(this, "My Service Created", Toast.LENGTH_LONG).show();
}
#Override
public void onStart(Intent intent, int startid) {
//Toast.makeText(this, "My Service Started", Toast.LENGTH_LONG).show();
sendEmail();
}
#Override
public void onDestroy() {
}
public void sendEmail()
{
Intent i = new Intent(Intent.ACTION_SEND);
i.setType("text/plain");
i.putExtra(Intent.EXTRA_EMAIL , new String[]{"myEmail#example.com"});
i.putExtra(Intent.EXTRA_SUBJECT, "subject of email");
i.putExtra(Intent.EXTRA_TEXT , "body of email");
try {
startActivity(Intent.createChooser(i, "Send mail..."));
} catch (android.content.ActivityNotFoundException ex) {
Toast.makeText(EmailService.this,ex.getMessage(), Toast.LENGTH_SHORT).show();
Toast.makeText(EmailService.this, "There are no email clients installed.", Toast.LENGTH_SHORT).show();
}
/*try {
startActivity(Intent.createChooser(i, "Send mail..."));
} catch (Exception ex) {
Toast.makeText(EmailService.this,ex.getMessage(), 10).show();
//Toast.makeText(EmailService.this, "There are no email clients installed.", Toast.LENGTH_SHORT).show();
}*/
}
}
and on the mainForm :
package com.application.outgoingemail;
import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
import android.widget.Toast;
public class main extends Activity implements OnClickListener{
/** Called when the activity is first created. */
Button Button1,Button2;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
Button1=(Button)findViewById(R.id.button1);
Button1.setOnClickListener(this);
Button2=(Button)findViewById(R.id.button2);
Button2.setOnClickListener(this);
}
public void onClick(View v) {
// TODO Auto-generated method stub
switch (v.getId()) {
case R.id.button1:
startService(new Intent(main.this, EmailService.class));
break;
case R.id.button2:
stopService(new Intent(main.this, EmailService.class));
break;
default:
break;
}
}
}


you can do by this way ::
Intent i = new Intent(Intent.ACTION_SEND);
i.setType("text/plain");
i.putExtra(Intent.EXTRA_EMAIL , new String[]{"recipient#example.com"});
i.putExtra(Intent.EXTRA_SUBJECT, "subject of email");
i.putExtra(Intent.EXTRA_TEXT , "body of email");
try {
startActivity(Intent.createChooser(i, "Send mail..."));
} catch (android.content.ActivityNotFoundException ex) {
Toast.makeText(MyActivity.this, "There are no email clients installed.", Toast.LENGTH_SHORT).show();
}

Can't dismiss dialog in Android

I don't know why my dialog can not be dismissed. Actually, I see in my database, the data we take successfully gets saved in that database. Just the dialog dismiss code is not working.
This is my code:

dialog.dismiss();
}
}
#Override

});
}
}
Result just run dialog without dismiss dialog:
If you have any ideas or advice, I realy apreciate it.
Thanks

Just tried your code, and it works perfectly.
Make sure you have an 'else' clause in your onResponse, and dismiss the dialog in onFailure as well
#Override
public void onResponse(Call<Users> call, Response<Users> response) {
if(response.body().getResponse().equals("ok")){}
else if(response.body().getResponse().equals("failed!")){}
else if(response.body().getResponse().equals("already")){}
else {
Toast.makeText(EmailRegisterActivity.this, "Do'h, I forgot to put and 'else' clause", Toast.LENGTH_SHORT).show();
dialog.dismiss();
}
}
#Override
public void onFailure(Call<Users> call, Throwable t) {
Toast.makeText(EmailRegisterActivity.this, "Do'h, Failure :(", Toast.LENGTH_SHORT).show();
dialog.dismiss();
}

Try this its working....set in stop button...always cancel pending intent after creating it
alarmManager = (AlarmManager)getSystemService(ALARM_SERVICE);
myIntent = new Intent(MainActivity.this, MyService.class);
btn1.setOnClickListener(new OnClickListener() {
#Override

alarmManager.cancel(pendingIntent);

// TODO Auto-generated catch block
e.printStackTrace();
System.out.println("ex....."+e);
}
Calendar calendar = Calendar.getInstance();
calendar.setTimeInMillis(System.currentTimeMillis());
calendar.add(Calendar.SECOND, 10);
alarmManager.setRepeating(AlarmManager.RTC_WAKEUP, calendar.getTimeInMillis(),10000, pendingIntent);

#Override

e.printStackTrace();
System.out.println("ex....."+e);

MainActivity.this.stopService(myIntent);

You need to set this flag:
in.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
So your Startapp method will look like this:
public void Startapp()
{
Intent in = getPackageManager().getLaunchIntentForPackage("com.example.application");
in.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
startActivity(in);
Toast.makeText(getApplicationContext(), "Counter : " + counter, Toast.LENGTH_SHORT).show();
}

I'm trying to make a Scheduled Auto sms sending, but i won't go far with this errors. PLEAS help.

You have a problem with your context being passed in as the error says. Replace this with getApplicationContext()
PendingIntent sentPI = PendingIntent.getBroadcast(getApplicationContext(), 0, new Intent(SENT), 0);
PendingIntent deliveredPI = PendingIntent.getBroadcast(getApplicationContext(), 0, new Intent(DELIVERED), 0);
Just replace those 2 lines !
Update :
I just tried that and it worked !

Thats it ! Try that !

The problem is the same for both lines. The method getBroadcast() is expecting a context as it's first argument. When you call this method you are inside of an anonymous inner class, in this case an onClickListener class. When you provided the this keyword as the first argument, this refers to that onClickListener class. What you need instead is to grab the context of the application which you are currently in and provide that to the method. You can achieve that by changing the error causing lines like this.
PendingIntent sentPI = PendingIntent.getBroadcast(MainActivity.getApplication(), 0, new Intent(SENT), 0);
PendingIntent deliveredPI = PendingIntent.getBroadcast(MainAcitivty.getApplication(), 0, new Intent(DELIVERED), 0);
Replace this with MainActivity.getApplication().

Android Limiting signup for one user

I developed an android application ... It is an applications first page... two buttons it have ... signup and sign in .. when user enter for first time he needs to signup and when sign up is pressed registration process will start ... user has to give an username, password and a mobile number .. once he give all this a passcode will be generated annd will be send to the mobile number provided user has to enter this passcode recieved along with the username and password to register... once he got register .. he can signin with the username and password.
Al these part is working fine ... My requirement is to limit the registration for only 1 username.... so for one download one username is allowed .. after one registartion the signup option must deactivated... so what I have to do for that .. I am giving the code ..below...

To make it simple
Just get the count of the LOGIN Table. If it returns 1 then hide the SignUp button otherwise show the SignUP button. Use the following line of code to get the total count of the table.
In Activity
if(loginDataBaseAdapter.getUsercount()==1){
btnSignUp.setVisibility(View.INVISIBLE);
}
In Database
public long getUsercount() {
return DatabaseUtils.queryNumEntries(db, "LOGIN");
}
It should work.

A quick simple approach would be to use a "marker" that carries a value indicating if they created an account or not. You can use a boolean or an int.
So your programming logic would go as such:

If the message has been sent, then remove the number from your database or add some information in the database that the message has been sent. Then mDbHelper.selectAllNumbers() can return only the numbers that need to receive the message.
