android: self signed apk can install in emulator but not in device

Question

I wrote a small program and created a signed apk in eclipse kepler.

I cannot install the apk into my device through dropbox with "Unknown source" option UNCHECKED. The option is under Setting -> Security.

However, I can install the apk into my emulator by using

adb install abc.apk

The emulator still got "Unknown Source" UNCHECKED.

Could anyone help? Thank you very much!

Regards,

Antony

Answer 1

It will also work via ADB on the actual device while unknown sources is unchecked.

However, if you want to install the APK right from your device using a file management app, you will have to enable installations from unknown sources.
