我制作的Android App不会安装但在模拟器中工作正常吗？

Question

I'm having an issue installing an exported, unsigned .apk on my android device. I have an HTC Droid Incredible 2 and can't get my apk to install. Whenever I try to with the Astro File Manager app or AppInstaller app it prompts me for the install and everything, says the permissions it uses, and then when I hit the "Install" button it shows the loading bar for about half a second and then says "Application not installed" and I have no way to debug or anything on my phone because the Incredible 2 will not connect to my PC no matter what I enable or try and it won't show on adb.

Here's a copy of my Manifest, is there anything that could be causing an install issue, or something I left out? It runs on my emulator with 0 problems.

Answer 1

You need to sign your .apk file or else Android won't install it. When you are running it on the emulator, or a device through eclipse, the .apk is signed with a certain debug certificate which allows installation.

Answer 2

Have you enabled the Unknown Source in your mobile device. As you are installing unsigned apk you have to enable the Unknown Source. To enable go to settings -> Applications -> check the Unknown source in the list -> click on ok button.
