Hi friends, I am having an issue with the release-unsigned.apk generated after run meteor build --server :, I am following this tutorial of Meteor with Ionic 2:
Exactly step 6 “Messages pages”.
In the web everything is ok, but in my cell I can not install the apk.
Please help me

Have you signed the APK and zipped it? You can’t install on the device until that is done. Also ensure that developer mode is enabled on the device.

I also seem to recall having to serve the apk file (from something like google drive) rather than copying the file straight over in order to have play store recognize it correctly.
