Build problem on Android Studio

[MartinCorteza]

I'm having a strange issue building my own version of Voice in Android Studio. I need my special build because Paul changed the bookmark info some time ago so it's not useable for me any more. Fortunately I found the file and part of the code which when commented out puts Voice back to previous bookmark mode. This worked for me with the 8.2 branch on Intellij IDE. With the recent 8.6 branch, I had to switch to Android Studio, because the Gradle version on Intellj IDE is too old to support building this version.
Long story short - I can build the APK in Android Studio. But when I install it on my phone, it creates TWO menu entries and the folder search process seems to have some difficulties. I'm using Android Studio on Windows in the default setup with the bundled JDK, only Gradle seems to need more heap memory, which I provided with a changed entry in gradle.properties.
I'm not an Android developer. Though I know how to work with IDEs and programming languages, I'm obviously missing something. Any expert (or Paul?) here to put me on the right track?

What do you mean by "two menu entries" and by "some problem with search"?

[MartinCorteza]

While installing the APK, two entries are created in the app list - see first screenshot attached. When I start Voice, the usual folder dialog comes up and lets me choose my audiobook folder. This is like it should work. But when I press the final "start" button, I don't see the list of audiobook folders been updated. Instead my build of "Voice" asks me to choose the audiobook folder again (see second screenshot). When I close the app and start it again, everything is fine and I can see the audiobooks. But together with the double app list entry, it feels that there is something wrong with my build.

I don't think something is wrong with your build.

The two menu entries were a bug (just fixed upsteam)

Regarding setup:
I created some basic docs to setup the project:

Regarding that bug: Maybe you can investigate more why that happens!
