Android : Couldn't create directory for SharedPreferences file
I am trying to edit SharedPreferences of one app through another app, my code goes like this
try {
Context plutoContext = getApplicationContext().createPackageContext("me.test",Context.MODE_WORLD_WRITEABLE);
SharedPreferences plutoPreferences = PreferenceManager.getDefaultSharedPreferences(plutoContext);
Editor plutoPrefEditor = plutoPreferences.edit();
plutoPrefEditor.putString("country", "India");
plutoPrefEditor.commit();
}
I am getting an error
E/SharedPreferencesImpl( 304): Couldn't create directory for SharedPreferences file /data/data/me.test/shared_prefs/me.test_preferences.xml
where me.test is my another project in me.test proj I can edit and retrieve SharedPreferences with no pain
I am testing it on Nexus S android 4.0.4 (Samsung), can any one help me
You need to add the permissions in your AndroidManifest.xml:
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE"/>
I have the same problem with you, and I solved it with the above solution.
Just use a different package name in this app. That will create the preferences in a different directory.
By the way, (it's not related with the question, but any way) you wrongly use createPackageContext() method. You pass there MODE_WORLD_WRITEABLE flag which value is 2 and equals to CONTEXT_IGNORE_SECURITY flag, so this would be incorrectly interpreted by logic, IMHO.
