Can't install the application to Microsoft Android phone simulator

in Xamarin.Android

I used Azure DevOps to build a simple Android application and later passed to App center for apk downloading. After I drag and drop the apk to the Microsoft Android phone simulator, I get an error message:

The APK failed to install.
Error: Could not parse error string

I am aware of this thread in stackflow:

I have made sure the build is for x86 and have downloaded the latest SDK Manager, but still I couldn't install the SDK.

Any help will be greatly appreciated.

    I finally successfully installed the app after signing the app, and change the .csproj file to have platform =x86

    Did you install the application on the enulator before? If the same application is already installed with the same version on the Emulator, then it won't get update/install. the error will be thrown.

    Try the following tips:

    • Uninstall the old APK from Emulator, then drag & drop the new APK to install the application
    • Change the version number from project->Properties, then reinstall the apk.

    I did uninstall the application on the emulator, and I got the same error message trying to install it.

    Also, do you know how I can change the version number in Azrue DevOps build? I looked at all the options for XamarinAndroid and didn't find one for version number

    Thanks!
