Hi all,

My app not installing in release mode, Even I tried generating apk and installing but app is crashing every time.
I'm getting following error

Start debugging Android application failed
Start debugging Android application ...

am start -a "android.intent.action.MAIN" -c "android.intent.category.LAUNCHER" -n "com.test.demo/crc6409718adb1cab00c7.SplashActivity"
Starting: Intent { act=android.intent.action.MAIN cat=[android.intent.category.LAUNCHER] cmp=com.test.demo/crc6409718adb1cab00c7.SplashActivity }

Error type 3
Error: Activity class {com.test.demo/crc6409718adb1cab00c7.SplashActivity} does not exist.

The application could not be started. Ensure that the application has been installed to the target device and has a launchable activity (MainLauncher = true).

Additionally, check Build->Configuration Manager to ensure this project is set to successfully
for this configuration.

    For me this was an emulator issue. Uninstall the previously deployed app on the emulator, then try again.

    For me, this worked as a charm!

    In Android Adb Command Prompt, type

    adb -s <DEVICE> uninstall <PACKAGE>

    should give you the word Success

    adb -s <DEVICE> shell pm trim-caches 99999999

    I also got the error: run-as with Studio On MAC

    For my case. When I copy a new Page. Then change namePage.xaml, NamePage.xaml.cs, Name ModelPage.cs, there is an error always occurs at the line InitializeComponent();

    Although everything is always correct, it seems that there is still a problem with Visual Studio.

    So the first solution is to Close Visual Studio -> Save Solution. Then reopen the Project.

    The second solution is to Rebuild Solution.

    Hopefully those 2 ways will

    To Xiaomi users: if you have second space activated on your phone and you've uninstalled the app that you're debugging, you also have to uninstall it on your second space (if it is installed there) or else you won't able to redeploy the app.

    I got this error, went into Settings, Apps, found the app in question, it said 'not installed for this user' I tapped on it, from the menu chose 'uninstall for all users' Then I was able to run it again.
