What happens if I delete dump.txt file in Android studio?

Question

After finishing my project, I found that there is a huge (55 MB) dump.txt file inside app\build\outputs\mapping\release in android studio project. I googled and found that this is from ProGuard.

Now, my question is if I delete that file, will there be any problem? It's making my whole project size greater than 100 MB

Answer 1

dump.txt is a file created by ProGuard. As stated on developer.android.com:

describes the internal structure of all the class files in the .apk file

You can safely delete the file, the important thing to remember is to save in a safe place mapping.txt as it is necessary to debug the obfuscated APK. See Decoding Obfuscated Stack Traces for more information.
