Failed application output, successful deployment and build

Question

I'm building an application using Xamarin.Forms. It successfully runs on iOS, although, on Android crashes when I try to launch it.

According to the debugging:

• Builds successfully
• Deploys successfully
• Fails when I try to launch

Here is the output from the application:

am start -n "com.xamarin.app/md53ed91cd16174c53d73a3021495ff3392.MainActivity"
Starting: Intent { cmp=com.xamarin.app/md53ed91cd16174c53d73a3021495ff3392.MainActivity }

Any help would be appreciated!

You can continue compiling your App targeting the latest version but to be able to run it on oldest version you need to set your minimum SDK version.

On Xamarin Studio this can be done from the Android project options going into the Application session.

This settings says that I am compiling using my latest installed SDK (24) but this app is supported down to version 19 (Android 4.4) which is called KitKat if I am not wrong.

Be aware that if you change the Target Android Version in this session you must also change the target framework in the General and viceversa.
