To test in-app purchasing, you build needs to match what is deployed on Google Play very closely:
* you must sign with the same release key, currently our build system needs an absolute path for the ANDROID_KEYSTORE variable.
* you must provide the correct SIGNING_PUBKEY, you get this from the Google Play Publisher dashboard where it says "YOUR LICENSE KEY FOR THIS APPLICATION".
* your android version number must match a Google Play deployed APK, you set this using BUILD_TIMESTAMP=1384026518, or VERSION_CODE=1384026518
Please try this:
$ BUILD_TIMESTAMP=1384026518 SIGNING_PUBKEY="<LICENSE_KEY>" ANDROID_KEYSTORE='/Full/Path/To/my-testing-release-key.keystore' ANDROID_KEY_NAME=mytestingkeys ANDROID_KEYSTORE_PASS=password'' apportable load
You can also add "-v signing" to check that the signing is successful with the expected arguments to jarsigner.
