Android permission error when getting getAccountsByType

Question

Hi i am trying to get an existing account i've recently created using:

 AccountManager am = AccountManager.get(activity);
        Account[] acc = am.getAccountsByType( activity.getResources().getString(R.string.ACCOUNT_TYPE));

and my manifest

on="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
          package="com.test.sample"
        >

    <!--<uses-permission android:name="android.permission.GET_ACCOUNTS" />-->
    <!-- Request permission to use a device camera -->
    <uses-permission android:name="android.permission.CAMERA"/>

    <uses-feature android:name="android.hardware.camera2"/>

    <uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE"/>
    <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>
    <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE"/>

    <uses-permission android:name="android.permission.READ_SYNC_SETTINGS" />
    <uses-permission android:name="android.permission.WRITE_SYNC_SETTINGS" />
    <uses-permission android:name="android.permission.READ_SYNC_STATS" />

    <uses-permission android:name="android.permission.READ_CALENDAR"/>
    <uses-permission android:name="android.permission.WRITE_CALENDAR"/>
    <uses-permission android:name="android.permission.READ_CONTACTS" />
    <uses-permission android:name="android.permission.WRITE_CONTACTS" />

    <!-- client -->
    <uses-permission android:name="android.permission.USE_CREDENTIALS"/>
    <uses-permission android:name="android.permission.GET_ACCOUNTS"/>
    <uses-permission android:name="android.permission.MANAGE_ACCOUNTS"/>

    <!-- Authenticator -->
    <uses-permission android:name="android.permission.INTERNET"/>
    <uses-permission android:name="android.permission.AUTHENTICATE_ACCOUNTS"/>

    <application
           ...

        <service
            android:name="com.test.sample.AccountAuthenticatorService"
            android:exported="true" android:process=":auth"
            >
            <intent-filter>
                <action android:name="android.accounts.AccountAuthenticator" />
            </intent-filter>

            <meta-data
                android:name="android.accounts.AccountAuthenticator"
                android:resource="@xml/authenticator" />
        </service>

    </application>

</manifest>

getAccountsByType required GET_ACCOUNTS permission which I already added into manifest but still I get this error:

java.lang.RuntimeException: Unable to start activity ComponentInfo{com.test.sample/com.test.sample.activities.MainActivity}: java.lang.SecurityException: caller uid 10340 lacks any of android.permission.GET_ACCOUNTS

I googled to this:

Permissions Not Working

but still getting the same error. This error only happens on android devices(multiple samsung devices) but was fine in emulators.

Anyone knows any other solutions that might work?
