Fix wrong adb path selection

[ema987]

First of all, thank you very much for this amazing project!

Issue description:

• use the standalone app or the IntelliJ Idea plugin for time travelling
• start time travelling by clicking the debug icon
• select an executable which is not adb
• the app/plugin still try to execute it without successful result
• try to start again the time travelling by clicking the debug icon, the app/plugin still tries to launch the executable selected earlier (which is not adb) ending in an error.

Now you can't anymore select the right adb executable and you're stuck with an unusable app/plugin.

It looks like to me the right checks are in place to avoid select an executable which is not adb in the file selection dialogs but the filters/checks are not respected, at least on my Macbook with BigSur 11.4 and IntelliJIdea plugin version 3.0.0-alpha01.

I improved the adb path selection manually checking a file named adb is selected in the file selection dialog. Furthermore, everytime you start debugging, the code checks the selected path is an adb executable, otherwise it prompts you the file selection dialog.

This is a quick fix and unfortunately duplicated in some places.

IMHO, in a future version, it would be better to create a new button to make the user able to select the adb path anytime, so it can be changed when needed and some checks can be removed.

I hope this is useful!

Thank you very much for the fix! Seems like on macOS the file name filter is ignored and you can actually select any file. On Ubuntu (my machine) it works fine and allows only adb files to be selected.

Thank you for the fast response! The code should now be fixed as you asked
