How to auto fill the email edittext with the email id by which the device is registered

Question

I want to auto-complete an emailId EditText with the gmail-id registered with the device. e.g if my phone is registered with the gmail id [email protected] then it should be auto completed as i start typing "s". Any Ideas??? Thanks...

Answer 1

You have to go through Android AccountManager class:

AccountManager manager = (AccountManager) getSystemService(ACCOUNT_SERVICE); 
Account[] list = manager.getAccounts();

and also need to add required permissions to AndroidManifest file:

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

From there you can autofill info.

Answer 2

Firstly set this permission in your AndroidManifest.xml file

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

The Java code:

//declaration

String possibleEmail="";

//onCreate

EditText emailEdt=new EditText(this);

 Account[] accounts = AccountManager.get(this).getAccounts();
for (Account account : accounts) 
{

  // TODO: Check possibleEmail against an email regex or treat

  // account.name as an email address only for certain account.type values.
    possibleEmail = account.name;

}
emailEdt.setText(possibleEmail);
