Sugar ORM: Class cast exception when trying to cast a context from getApplicationContext()

Question

I tried to cast a context to an Activity. I need to do this to call one of that activity's method. To get the context I need, I used getApplicationContext(). The application that I am developing right now is using Sugar ORM as the database framework. Here is the code and the exception that I got.

ContentResolver.requestSync(((MainActivity) getApplicationContext()).getAccount(), AccountHelper.AUTHORITY, settingsBundle);

java.lang.ClassCastException: com.orm.SugarApp cannot be cast to id.ac.ui.presentronik.activity.MainActivity

It seems that the problem I encountered is same with one in this question: SugarORM in AndroidManifest. But the solution only works with a Fragment. Is there any other way to get a correct context from an Activity?

any solution for this facing same issue here.. – Shailendra Madda Dec 26 '16 at 05:46 — Shailendra Madda, Dec 26 '16 at 05:46

com.orm.SugarApp cannot be cast to id.ac.ui.presentronik.activity.MainActivity

Pass in getActivity() as the context:

ContentResolver.requestSync(getActivity().getAccount(), AccountHelper.AUTHORITY, settingsBundle);

OR

ContentResolver.requestSync(((com.orm.SugarApp) getApplicationContext()).getAccount(), AccountHelper.AUTHORITY, settingsBundle);

Remember in your manifest you set something like this:

<application
    android:allowBackup="true"
    android:icon="@mipmap/ic_launcher"
    android:label="@string/app_name"
    android:theme="@style/AppTheme" 
    tools:replace="android:icon"
    android:name="com.orm.SugarApp">

You also need to use these permissions:

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