Clear cache of app without force closing the app

Question

i need to clear cache of an app without force closing the app. i need app to continue running. i am using espresso to test application but i need to clear cache before the app starts. is there any possible way to do it ?

public static void clearPreferences(Activity activity) {
    try {
        // clearing app data
        String packageName = activity.getPackageName();
        Runtime runtime = Runtime.getRuntime();
        runtime.exec("pm clear "+packageName);

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

this is what i have. but it closes the app and terminates test case

Delete all of the files in `getCacheDir()`, using normal Java I/O classes, like `File`. — CommonsWare, Mar 01 '17 at 13:59
