title: I am not able to install my Android app on my Samsung galaxy pop
body: <p>I am facing a strange problem.  I created an apk of my application with unsigned key and tried to install it on my samsung galaxy pop, but i am not able to install it on my samsung galaxy pop. I enabled the option for installation of non market place app but i am getting unable to install message.</p>
  
  <p>However when i am connecting phone with USB and clicking on run it is getting installed in the device. </p>
  
  <p>is there anything wrong in my approach??</p>
