I was working in an app for some months and have created more than 10 versions, each one I tested with apk installed on android 7 and 9 devices.
Till August everything was running fine, in September all the builds became broken, the app force closes as soon as I press a button. The same thing now happens with all saved versions.
Unfortunately I deleted all build files, so now I don't have a working app. Interestingly all versions are running perfectly over previous Companion version, but Force Closes in the same behavior described over the last Companion version.
The routines that the button starts are just calculations an graphic plot of data received over BLE (that is constantly receiving without errors before I click the button).
If I don't find a solution I will be forced to abandon this project, and will fear spend so much time in another one.
Any help will be welcome.
