BlueStacks installation failed with previous sdk error

Hi everyone, I am trying to install an apk that I developed with minsdk version 14 and target 19 on bluestacks and it crashes. What's strange is that I installed the app with the same api version 14/19 on the same bluestacks player a month ago (I uninstalled it now though I replaced it with a new apk). Please let me know what api I should be developing for bluestacks. Here's my xml
