Getting the Gmail Id of the User In Android 6.0 marshmallow

Question

I am getting email id by using android.permission.GET_ACCOUNTS permission.

 try {
            Account[] accounts = AccountManager.get(this).getA         


        

Answer 1

Example as a separate service class to be easily used in different situations by calling getGMailAccount method.

public class GMailAccountService {

private static final int MIN_SDK_FOR_REQUESTING_GET_ACCOUNTS = 22;
private static final int GET_ACCOUNTS_PERMISSION_REQUEST_CODE = 112;

private Activity activity;

public GMailAccountService(Activity activity) {
    this.activity = activity;
}

public String getGMailAccount() {
    if(android.os.Build.VERSION.SDK_INT > MIN_SDK_FOR_REQUESTING_GET_ACCOUNTS){
        if(!isGetAccountsPermissionAllowed()){
            requestGetAccountsPermission();
            return getGMailAccount();
        }
    }
    return extractAddressFromAccountManager();
}

private boolean isGetAccountsPermissionAllowed() {
    int result = ContextCompat.checkSelfPermission(activity, Manifest.permission.GET_ACCOUNTS);
    if (result == PackageManager.PERMISSION_GRANTED)
        return true;
    return false;
}

private void requestGetAccountsPermission(){
    ActivityCompat.shouldShowRequestPermissionRationale(activity, android.Manifest.permission.GET_ACCOUNTS);
    ActivityCompat.requestPermissions(activity,new String[]{android.Manifest.permission.GET_ACCOUNTS}, GET_ACCOUNTS_PERMISSION_REQUEST_CODE);
}


public String extractAddressFromAccountManager(){

    Pattern emailPattern = Patterns.EMAIL_ADDRESS; // API level 8
    Account[] accounts = AccountManager.get(activity).getAccountsByType("com.google");
    for (Account account : accounts) {
        if (emailPattern.matcher(account.name).matches()) {
            return account.name;
        }
    }
    return null;
}

}
