aidl oneway keyword error

Summary:

Move the oneway keyword to the method level.

Explanation-
This is very weird problem that related to the /platform/frameworks/base/api/current.txt file inside the Android framework (Big txt file that contains every function and being used by Android Studio) .

Example-

/** Interface implemented by Apkinson so plugins can give feedback */
interface IApkinsonCallback {
    /** To be called by plugin after registration to setup data for result viewing
        Usage of this data:
        Intent intent = new Intent(intentActionName);
        intent.putExtra(bundleResultKey, result);
        startActivity(intent);
     */
    oneway void onRegistered(String intentActionName, String bundleResultKey);
    /** To be called by plugin when result is ready after stopData() was called by Apkinson */
    oneway void onResult(String result);
    /** Called if an error occured in the plugin and the call won't be successfully handled */
    oneway void onError(String errorMsg);
}

You will get the same result but without the error.
