Issues:
Android Studio no longer recognizes standard system and JNI headers from the NDK in C++ files.
Android Studio can no longer generate new JNI functions for native java functions.

Steps to reproduce:
1. Install Android Studio 3.2.1 (the latest version 3.3 is too broken to use. See issue: 123071299, as well as 3.4 beta1 - See issue: 123071300)
2. Use all default locations and proposed items to install
3. Create a new Mobile project with C++ support. See attached images Step1-6
4. Install NDK as proposed by Gradle
5. Install CMake as proposed by Gradle

After all the Gradle Syncs and indexing you should be looking at a situation as displayed in Capture1 (Sorry about the Snipping Tool overlap).

Two major issues become apparent immediately:
1. The broken interlink between the wizard generated "stringFromJNI <-> Java_com_example_alesom_testapp_MainActivity_stringFromJNI" can already be observed (no red/green arrows on the left side of the window that allow a jump from Java to Native code and vice versa).
2. Native code is all red from "syntax errors" and neither jni.h and string include files are recognized

To make sure that the initial lack of NDK and CMake didn't spoil the broth, I repeated the same procedure a second time with NDK and CMake installed.

Steps to reproduce:
1. Create a new Mobile project with C++ support. See attached images Step1-6

After all the Gradle Syncs and indexing you should be looking at a situation as displayed in Capture2.

Again both issues appear:
1. The interlink between the wizard generated "stringFromJNI <-> Java_com_example_testapp_MainActivity_stringFromJNI" is half broken with the red/green arrows on the left side of the window only in Java but not in Native code.
2. Native code is all red from "syntax errors" and neither jni.h and string include files are recognized
3. It is not possible to get rid of the Failed Gradle Sync status on top of Java and C++ windows. The sync appears to be successful and it IS possible to build and run the application.
To resolve the Sync issue the following was attempted:
1. Build -> "Refresh Linked C++ Projects"
2. File -> "Sync Project with Gradle Files"
3. Android Studio restart

After step 3 the Failed Gradle Sync notification as gone.

Further issues:
1. The wizard for creating JNI functions from Java native method definitions is no longer working.

Steps to reproduce:
1. Define a sample function in Java code: public native String test();
2. Place the text cursor on the function name test() displayed in red and press Alt-Enter for the context menu to appear
3. Choose Create function .....

This will generate a partial code snippet in the middle of the definition of the previous JNI function.

This makes the development process for developer leaning on JNI at a total loss.
