Issue solved.

Cannot take an .apk file created in debug mode.

  1. Build project using Release mode.
  2. select Build > Archive for Publishing

This will produce a final apk file. we can install and use this apk file without any problems.

Read more about here: http://docs.xamarin.com/guides/android/getting_started/installation/set_up_device_for_development

Edit your .csproj,

Change:

<AndroidUseLatestPlatformSdk>True</AndroidUseLatestPlatformSdk>

To:

<AndroidUseLatestPlatformSdk>False</AndroidUseLatestPlatformSdk>

Then clean, rebuild and reinstall the apk
