Java – Android NDK ndk-build helloJni error

I’m trying to run the HelloJni program from an NDK sample. I’m using Eclipse Juno. Also, the “.so” file is not generated. But when ndk-build the project, I get the following message in the console:

**** Build of configuration Default for project HelloJni ****

You seem to be using Android-10 as runtime on your Android-19 device.

Put APP_PLATFORM:= android-10 into your Application.mk file.
