GoogleAuthUtil.getToken() method throws IllegalStateException

I've used GoogleApiClient object, inherited ConnectionCallbacks interface and calling GoogleAuthUtil.getToken(Context context, String accountName, String scope) from two different methods.

1. overriden onConnected() method of ConnectionCallbacks interface.

  1. onClick() method of button.

In both of these I am getting different response of getToken() method.

  1. while calling from onConnected() method: it throws error like: java.lang.IllegalStateException: Calling this from your main thread can lead to deadlock.

  2. In case while calling from onClick() method, it works fine!!!

What is difference between these 2 calls? onClick() executes in main thread. Right?

onClick() method:

@Override
public void onClick(View v) {
    getGoogleToken();
}

onConnected() method:

@Override
public void onConnected(Bundle arg0) {
     getGoogleToken();
 }

getGoogleToken() method:

private void getGoogleToken() {
    try {
        AccountManager am = AccountManager.get(MainActivity.this);
        Account[] accounts = am.getAccountsByType(GoogleAuthUtil.GOOGLE_ACCOUNT_TYPE);

        //Retrieve the google token
        String token = GoogleAuthUtil.getToken(getApplicationContext(), accounts[0].name, PRIVATE_KEY); // This line generates error.

        // ...

    } catch (Exception ex) {
        ex.printStackTrace();
    }
}

Here is stackTrace:

Try executing the below code block in a background thread.

new Thread(new Runnable() {
    public void run() {

     android.os.Process.setThreadPriority(Process.THREAD_PRIORITY_BACKGROUND);

        //Your code
try {

        AccountManager am = AccountManager.get(MainActivity.this);
        Account[] accounts =  am.getAccountsByType(GoogleAuthUtil.GOOGLE_ACCOUNT_TYPE);

        //Retrieve the google token
        String token = GoogleAuthUtil.getToken(getApplicationContext(), accounts[0].name, PRIVATE_KEY); // This line generates error.
        .......
        .....
        }catch(Exception ex)
        {
          ex.printStackTrace();}
        }
}).start();
