Get List of Youtube channels subscribe by current user in android?

Hello I want to get list of channels subscribe by current user in android.

Steps I follow:

1) https://developers.google.com/youtube/v3/docs/subscriptions/list

By read the description, I created API key for android and oauth key in google developer console and tired to implement following request

GET https://www.googleapis.com/youtube/v3/subscriptions?part=snippet&mine=true&key={YOUR_API_KEY}. you can see I have set only part = snippet and mine = true.

For authentication I followed https://developer.android.com/training/id-auth/authenticate.html

Here is my code

AccountManager am = AccountManager.get(this);
Bundle options = new Bundle();

am.getAuthToken(
    myAccount_,                     // Account retrieved using getAccountsByType()
    "Manage your tasks",            // Auth scope
    options,                        // Authenticator-specific options
    this,                           // Your activity
    new OnTokenAcquired(),          // Callback called when a token is successfully acquired
    new Handler(new OnError()));    // Callback called if an error occurs

After adding proper permission I can get my account in myAccount_

on call backbaack of TokenAcquire

private class OnTokenAcquired implements AccountManagerCallback<Bundle> {
    @Override
    public void run(AccountManagerFuture<Bundle> result) {
        // Get the result of the operation from the AccountManagerFuture.
        Bundle bundle = result.getResult();

        // The token is a named value in the bundle. The name of the value
        // is stored in the constant AccountManager.KEY_AUTHTOKEN.
        token = bundle.getString(AccountManager.KEY_AUTHTOKEN);
        ...
    }
}

I am not getting the token value.

Please guide me. Is there some alternative approach Or if have to update/modify something?

My permission in xml are

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

I am getting error at this line token = bundle.getString(AccountManager.KEY_AUTHTOKEN); in my catch of exception handling.

android.accounts.AuthenticatorException. Attempt to invoke virtual method 'java.lang.String android.os.Bundle.getString(java.lang.String)' on a null object reference

I am using android 6.0 and it require run time permission.

To successfully get the access token according to Obtain an access token, I think you need to use a valid scope which is 'https://gdata.youtube.com' for Youtube API. However, looking at your code, it seems you passed "Manage your tasks" as Auth scope. Try setting that to 'https://gdata.youtube.com' instead.

With regard to getting number of subscribers, try making a REST call in Android with the following URI GET request:

GET https://www.googleapis.com/youtube/v3/subscriptions?part=snippet&mySubscribers=true&fields=pageInfo&key={SERVER_API_KEY}

It returns a JSON response where totalResults represents the number of subscribers:

{
   "pageInfo": {
   "totalResults": 2,
   "resultsPerPage": 5
  }
}
