I made a android application on my pc. I kept the build sdk at 4.1, and minimum sdk version at 2.2 The app ran fine on the emulator but when i tried it on my friends Samsung Note it after installing gave an error "Application Not installed". I did so on Google Nexux 7.

I exported the app as a unsigned apk

I tried a simple hello world ap but had the same problem. Please help what to do and how to correct the error.

您需要对应用程序进行签名以使其在真实设备上运行.. 简单地选择导出为已签名的 apk 并使用密钥库对其进行签名...如果您没有，您可以通过与您相同的向导创建一个新的密钥库导出时获取
