Hello all

I have a tested MAUI application and run perfect in Android emulator (all functions)

When I deploy application to the store (AAB) and download it to the mobile for internal testing, firstly run OK but when I tap on the screen app crash.

Do you have any idea how to catch en error, and how can I test application?

PS: I "gues" an error occure in MAUI component not webview's JavaScript (touch events /DOWN/UP/MOVE/ are bubble from JavaScript to MAUI)

Generate Javascript more than one down(touch) event for one tap?

thanks for direct me and any help

    Hello,

    Do you have any idea how to catch en error, and how can I test application?

    When an Android application crashes on a device, it will leave a log file locally. For issues such as program crashes and flashbacks on physical devices, you can view local crash logs using the logcat command of the Adb tool provided by Google.

    Please refer to the following document:

    Hallo all

    I found problem and solution (problem with culture info)

    1. I made MAUI windows version of app (off Android app)
    2. MAUI windows app version revealed me conversion bug (culture problem) from Javascript string to MAUI double
    3. Bug: System.FormatException: 'The input string '0.2265625' was not in a correct format.'
    4. This
    double.Parse(data[0].Replace(",", "."))

    I replaced with this:

    double.Parse(data[0].Replace(",", "."), CultureInfo.InvariantCulture);
    1. Both versions Android and Windows are correct now

    Thanks you Alec, logcat util I didn't use, but it is interesting idea for next time

    best regards
