Unable to start an Activity from Application class - Android

Question

I am trying to access if user is logged in or not, based on that I try to start activity for the application. While doing this, the app crashes in the Application class.

The code for application class is

public class MyClass extends Application {
    public static Context context;

    @Override
    public void onCreate() {
        super.onCreate();
        context = getApplicationContext();

        if(ParseUser.getCurrentUser().isAuthenticated()){
            startActivity(new Intent(context, MainActivity.class));
        }

    }
}

Any suggestion why this happens ?

In my Manifest I have declared the intent filter for another activity.

 <activity
            android:name=".Activities.Register"
            android:label="@string/title_activity_register" >
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>

Answer 1

Intent intent = new Intent(context, MainActivity.class);
intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
startActivity(intent);

Also if you look at Logcat in Android Studio, you should be seeing error log that has already told you how to fix this issue.
