Fetching User's Email ID

Hi guys in this tutorial I am going to be showing you how to fetch the user's email Id which has been tied to the users device. This is a very short & simple tutorial so without wasting further time lets get to work :

================================================================
MainActivity.java
================================================================

package com.example.testemail;

import android.os.Bundle;

import android.app.Activity;

import android.content.Intent;

public class MainActivity extends Activity {

    @Override

    protected void onCreate(Bundle savedInstanceState) {

        super.onCreate(savedInstanceState);

        setContentView(R.layout.activity_main);

        String emailId = getEmailId();

        Toast.makeText(getApplicationContext(), emailId, 500).show();

}

   public String getEmailId(){

      Account[] accounts=AccountManager.get(this).getAccountsByType("com.google");

    

   

    for(Account account: accounts)

    {

        String emailId=account.toString();

        Log.d("List of  email id's of user", emailId);

    }

     String myEmailid=accounts[0].name;

    return myEmailid;

   }

}

================================================================

You also need a permission to access the Accounts 

<uses-permission android:name="android.permission.GET_ACCOUNTS" /> 

So add the above permission to your Manifest file.

================================================================

So, let me quickly explain what i did above :
1) I created a method which fetches the User's email ID
2) Here we get a Array of Accounts using the AccountManager, notice "getAccountsByType("com.google");" 

that is used to to get all Gmail Accounts configured in the users device

3) "accounts[0].name"  gives me the Email Id of the first Account of the user, which is most likely to be the users actual Gmail Id.

4) Finally added a permission of GET_ACCOUNTS required to access the accounts.

Thats all there is, this is used to fetch user's gmail Id programmatically.

================================================================

Note : Try this on a actual device rather than a emulator because the emulator has no Email Id by default .
