Where to find all the classes of installed Android SDK source code?

Question

I installed the Android API 28 Platform in Android Studio's SDK Manager so that I could look through the source code. In the External Libraries package in Android Studio, there is a package called <Android API 28 Platform>, which I assumed contained the source code.

While looking through the GLSurfaceView class, I noticed that the class EGLLogWrapper wasn't visible in Android Studio at External Libraries -> <Android API 28 Platform> -> android.jar -> android -> opengl, which is where in the package it seemed it should be. However, when I went to Windows File Explorer and searched at Android -> Sdk -> sources -> android-28 -> android -> opengl, the class EGLLogWrapper (as well as some other classes not shown in Android Studio), were found there.

I found that by right-clicking on android.jar (in <Android API 28 Platform>) and selecting "Show in Explorer", the File Explorer opens up the location at Android -> Sdk -> platforms -> android-28, where the android.jar is located. But this doesn't seem to be the source code that I installed. The classes that are visible within Android Studio all show that their File Explorer locations are in Android -> Sdk -> sources -> android-28 along with the classes that are missing in Android Studio. However, the only source code I can find within Android Studio is packaged under android.jar.

So my question is: how can I find the full Android API 28 source code that I installed from the SDK Manager in Android Studio? Because currently what I found in External Libraries isn't the full API.

You are not going to be able to find the source code from .jar files (unless you decompile). You can find the source code for API 28 here: https://github.com/AndroidSDKSources/android-sdk-sources-for-api-level-28

• 0xCursor: It does seem strange that the classes are under a .jar but I'm able to look at the source code for the visible classes anyway, although not all the classes are shown. When I open up the File Explorer location of the visible classes, their locations are in the folder path Android -> Sdk -> sources -> android-28 as opposed to Android -> Sdk -> platforms -> android-28. So I don't know if there is a way to just access the sources package within Android Studio.
