PD: Sorryfor my bad english and the format of the question this is my first question.

I had the same java.lang.ClassNotFoundException exception, trying to include jsoup.
What helped me was opening the terminal, going to the root of the project and executing
gradle clean
gradle assemble

Fatal error initializing plugin com.android.tools.ndk

I'm attempting to create my first project in Android Studio, and I'm encountering an IDE Fatal Error.
I've disabled the Android APK Support plugin along with the Android NDK support plugin, which has allowed me to successfully open a new Android Studio project; however, after a few moments, I'm receiving an IDE Fatal Error notification along with an exception report. This is also causing my layout code to produce multiple errors concurrently, wherein attributes and elements in my layout code are "not allowed here". I've tried invalidating caches and restarting, but it didn't fix the problem.

I created a new Android application project on MacOS and I faced this error when I tried to change GradleWrapper in Android Studio.

There's a chance an application has added jar libraries into your Mac's /Library/Java/Extensions directory.
Try removing or moving xercesImpl.jar to a temporary location. This has solved the problem on my Mac.

Please help me to solve this issue.
This issue you might got due to following reasons:
You might using some library in your projects which are either compiled using newer java version or older java version which is not supported by your machines jvm.
It might be possible that your Android Studio is corrupted so reinstalled it.
If you are trying to read the serialize object, which is serialized using old java version of new java version, and not supported by the jvm.
Hopefully this will help you.
Cheers

You can find the hierarchyviewer inside the your Android SDK under the tools directory.
