I downloaded my android app onto my phone to test it and when I try to install it the install just stops and says "Application not installed" or something like that. I'm not getting an error or anything so I can't figure out why it is doing this. Any ideas?

Try to see the error information in the log file. You can do that by:

  1. Plugging in your device into the PC;
  2. Run adb logcat to see the error you get when installing the application.

The problem may come from several places, therefore the best way to know what is happening is by checking the logs.

EDIT: I decided to include the official link of adb for the ones that are not familiar with it: Android Debug Bridge

Go to Settings -> Applications -> Check 'Unknown Sources'

I encountered a similar problem when I updated my manifest file.

I could load the program onto the phone, but the clicking its icon on the home screen gave me that error - it was probably uninstalled when I updated the manifest. However clicking the icon in the apps list worked fine.

Perhaps something similar happened in your case?

Try using an APK Manager/Installer

I assume you are using your .apk file and NOT trying to buy it on Android Market.

FYI Developers can not buy/download their own apps.
