We have an app that is fully operating in iOS and Android. The app locates statues in cities and get information from them by using GPS and a QR code reader. The information is audio recordings.
We have some problems with the android app, which are the scanner does not work, the functionality closes down when we use the build-in GPS. The GPS has no problem in finding the location but it will not receive the audio. And in the same way, the scanner does not work.
We need an experienced android developer to help us.
