Wrong argument count, format string [name] requires 0 but format call supplies 1

Question

I just can't figure out why I'm getting this error, I'm doing the exact same thing in another class, and it works fine (maybe it's an import?)

I want to do this:

SharedPreferences sharedPref = PreferenceManager.getDefaultSharedPreferences(this);
String downloadKey = getString(R.string.pref_download_folder_key); // This will return "pref_download_folder"
String downloadDefault = getString(R.string.pref_download_folder_default);
DownloadFolder = sharedPref.getString(downloadKey, downloadDefault);

But I'm getting the following error:

Wrong argument count, format string pref_download_folder requires 0 but format call supplies 1

When I change the line to this, everything works fine (note the downloadDefault works, despite being the exact same method):

DownloadFolder = sharedPref.getString("pref_download_folder", downloadDefault);

Thanks in advance!

It's an Android Studio bug. http://code.google.com/p/android/issues/detail?id=53238

Pressing "run" ran for me fine. You can also invoke

gradlew assembleDebug

or

gradlew assembleRelease

to build from a command line.

Edit: this is fixed a while ago, so if you see this in recent versions of Android Studio it's most likely the bug is in your code.
