[Q] when i use XPrivace.XPackageManager in my own module, error occurred, help me, urgent, thanks!

In the XPackageManager.java,
protected void after(XParam param) throws Throwable {
....
case Srv_getInstalledApplications:
if (param.getResult() != null)
if (isRestricted(param)) {
Method mGetList = param.getResult().getClass().getDeclaredMethod("ge tList");
List<ApplicationInfo> listAppInfo = (List<ApplicationInfo>) mGetList.invoke(param.getResult());
Constructor<?> constructor = param.getResult().getClass().getConstructor(List.c lass);
param.setResult(constructor.newInstance(filterAppl icationInfo(listAppInfo)));
}
break;
there throw exceptions: java.lang.NoSuchMethodException:getList[]
i log the class name use param.getResult().getClass().toString() the value is : class android.content.pm.ParceledListSlice,
but i can't import it use: import android.content.pm.ParceledListSlice;
how can i make the program run correct? thanks!
