Hi everybody!

I'm just starting to learn programming for android and working with Corona SDK. I have a trial version of Corona SDK, and i cannot install my simply created 'hello world' application on my telephone(real device, not virtual). When I'm typing:

adb install helloworld.apk

i got error:
Failure [INSTALL_PARSE_FAILED_NO_CERTIFICATES]

I will be very thankful for any ideas to solve my problem :)

This error happens if you have the JDK 7 (Java Development Kit) installed. JDK 7 digitally signs your APK with an encryption that Android does not support. You will need to uninstall JDK 7 and install the "32-bit" version of the JDK 6 instead. That will solve the problem.

problem solved, thanks for the reply :)
