I have a question, is there any save files on Android or will i lose progress if i change devices?

The Android save file is stored in your device only as I haven't implemented any kind of Cloud storage.
You can find the save file in this folder (connect the phone to a PC to be able to navigate here and copy everything in there):
\Android\data\com.DavidWu.DeliveringHope\files\save
I have never tried copying the save files between different devices, but hopefully it works for you.
Please let me know if it worked!
