 You can find adblock fragments in the 'libadblockplus-android-settings' directory:
 * GeneralSettingsFragment - main fragment
 * WhitelistedDomainsSettingsFragment - whitelisted domains fragment
 
 ### Usage
 
 Create `AdblockEngine` instance with factory methods and `AdblockSettingsStorage` instance.
 You can use `SharedPrefsStorage` implementation to store settings in `SharedPreferences`.
 Or you can use AdblockHelper:
 
-    AdblockHelper.get().init(this, true, AdblockHelper.PREFERENCE_NAME);
+    AdblockHelper.get().init(this, getFilesDir().getAbsolutePath(), true, AdblockHelper.PREFERENCE_NAME);
 
 Implement the following interfaces in your settings activity:
 
 * `BaseSettingsFragment.Provider`
 * `GeneralSettingsFragment.Listener`
 * `WhitelistedDomainsSettingsFragment.Listener`
 
 and return created instance or AdblockHelper instances:
 
     AdblockHelper.get().getEngine();  // engine
