Accessing Google Account Id /Username via Android

Accessing android Google Account Id /username via phonegap?

My suggestion would be to write the code for getting the Google Account info in Android Java like so:

http://developer.android.com/google/play-services/auth.html

And then create a JS interface to communicate with your webview to pass it the credentials like so:

How can I get the google username on Android?

As mentioned in the comments, Roman's answer to How to get the Android device's primary e-mail address solves it.
Here's the code i used that will also strip out the username from the email.

public String getUsername() {
    AccountManager manager = AccountManager.get(this); 
    Account[] accounts = manager.getAccountsByType("com.google"); 
    List<String> possibleEmails = new LinkedList<String>();

    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.
      possibleEmails.add(account.name);
    }

    if (!possibleEmails.isEmpty() && possibleEmails.get(0) != null) {
        String email = possibleEmails.get(0);
        String[] parts = email.split("@");

        if (parts.length > 1)
            return parts[0];
    }
    return null;
}

How do I retrieve the logged in Google account on android phones?

Something like this should work:

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

for(Account account: list)
{
    if(account.type.equalsIgnoreCase("com.google"))
    {
        gmail = account.name;
        break;
    }
}

And you will need the following permission in your manifest:

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

Remember to 'Requesting Permissions at Run Time' if you support Android 6 and later
https://developer.android.com/training/permissions/requesting.html

I wrote this from memory so it may need a little tweaking. Apparently it's possible to register now without an email address, so maybe do some regexing on the data to ensure it's actually an email address (ensure it contains @gmail or @googlemail)
