Troubleshooting an app in the phone

I made a qr code, and when I used it on my phone, it said 'downloading is not supported', then it doesn't download anything.



Several possibilities David,  ..the QR code will only download the app for a limited period of time; depending on the Android operating system on your phone, you will have to temporarily change the phone's download option settings as described at the end of these instructions.

Note: The other option (provide QR code for .apk) produces a scannable QR code that will download the app for two hours. You can share this code with others, but they have to use it within 2 hours of your generating it.

Once the build completes, you can email the app (".apk" file) to your friends who can install it by opening the email from their phone. If you want to distribute it more widely, you can upload it to a website that both you and your friend can access. You can also distribute your app on the Google Play Store.

NOTE: Anyone installing your app (which is an ".apk" file) will need to change the setting on their phone to allow installation of non-market applications:

To find this setting on versions of Android prior to 4.0, go to "Settings > Applications" and then check the box next to "Unknown Sources". For devices running Android 4.0 or above, go to "Settings > Security" or "Settings > Security & Screen Lock" and then check the box next to "Unknown Sources" and confirm your choice.

Did this allow you to get the app on your phone?     If not, instead of using the QR code, download the apk to your desktop, then email the apk to yourself and install that way.
