I'm using AIDE on my phone, and trying to open a fragment from the navigation drawer in-app, but I get this error when I try to build the app:
An instance of type 'android.app.fragmenttransaction' cannot be assigned to a variable of type 'android.support.v4.app.fragmenttransaction'
Here is the code in the MainActivity.Java file:

This line means that you are using FragmentTransaction; note that you are using the support lib's version, not the system's.
However, later in the code, you are assigning the support lib's FragmentTransaction to the native FragmentTransaction. They are incompatible and thus won't work. (Actually, it's what the error message itself is telling you.)
FragmentTransaction transaction = getFragmentManager().beginTransaction();
// ^^^ support lib's version ^^^ this code returns a native FragmentTransaction
You should instead get the support lib's fragment manager, which will return the support FragmentTransaction.
