What's the difference between 'armeabi' and 'armeabi-v7a'?

[James_Watson]

As far as I know, in source code directory of an Android Studio project, the sub-folder 'armeabi-v7a' of jniLibs is for 32-bit .so library files while 'armeabi-v8a' is for 64-bit ones.

But sometimes we will find the sub-folder named with 'armeabi' other than 'armeabi-v7a'. Is armeabi the same as armeabi-v7a?

Thank you all in advance.
