In you class, you should add static block to add conscrypt as security provider
static {
// add Conscrypt in list of security providers for device
Security.addProvider(Conscrypt.newProvider());
}

Exception "java.lang.ClassNotFoundException: Didn't find class..." on Android 4.4.2

When I try to run my existing application (using Android Studio 3.1.3) on Android 4.4.2 it is not running and showing this error:

Pay attention to the exception:

I found out that everytime when I try to run and it crashes the number in the exception increases my.project-5. (First time it was my.project-1, then my.project-2, and so on).
What is the problem and how can I fix this error?
Note: This error is also occuring on android 4.3. However, for android 5.0 and above it is working well.
Edit: Answer
After doing some research, I found the answer here:
NoClassDefFoundError with Android Studio on Android 4
https://developer.android.com/studio/build/multidex

I think you have a conflict with some code that requires at least android 5.0 but you are running in 4.4.2.
See the documentation here: https://developer.android.com/training/basics/supporting-devices/platforms and here: https://developer.android.com/guide/practices/compatibility
Post the code so we can help you better.

Cocos2d-x v3.7.1 Unfortunately, libcocos2dx has stopped

I'm compiling a new project through proj.android-studio using:
cocos compile -p android --android-studio
But when I start app on android device, it shows me a message:
Unfortunately, libcocos2dx has stopped
Can you help me? What I'm doing wrong?

Usually the app stops working if your code contains errors.
Are there errors in your code? What does the LogCat say?
