How to make folder selection in android?

Question

Java

I recently started learning android development. I am a little familiar with the Java language. I wrote a program that, according to a certain algorithm, renames files in a folder. The path to the folder is seized via cmd, and when the program exits, the path is serialized, and restored upon restart. Wrote in eclipse. And now I want to remake this program for android, I use android studio. And here is the question: How to make a "beautiful" folder selection? (Well, that is, the usual menu where you move through the folders and select the one you need, and do not write the path manually) And how to save the application settings in android? Should I use serialization or is there a better way? I'm not familiar with development for android, so if possible, in more detail .. Thank you!

You just have a string, why serialize it? We just write in SharedPreferences, and that's it.
