I have gone to the trouble of installing Java JDK (a prerequisite of running Android SDK / Android Studio), and have installed Android Studio/SDK. FINALLY after a couple hours installing these, and managing to get the Android IDE to actually run without throwing up errors (not an easy task itself), I FINALLY got it so I could start and run Android Studio. I then downloaded the FLIR One SDK including the sample app.
So I thought, "This is going to be easy from here on out, I'll just load the FLIR sample app, click a 'compile' button, copy the resulting APK file to my Android phone, and it will be good to go", but BOY OH BOY was I wrong. First it said that it needed to download the supporting files for the version of Android that the FLIR One SDK required, so I had to wait for it to autoupdate Android Studio with these files. Then when I FINALLY compiled it, there was no APK. The "build" button (unlike with other programming languages) does NOT generate a usable file. I had to search through menus and find a separate "make apk" button. So I clicked that, and got an APK file. So now I'm thinking "FINALLY I've got the working FLIR One SDK sample app", but again I was SO WRONG. I copy the APK file over to my phone and try to run it, but it appears to be a corrupt APK file, and my phone said that it was an invalid APK file!!!!!!!!!!
So now I'm going to do what I should have done from the start, ask for a step-by-step tutorial on these forums, a tutorial on EXACTLY what to do to configure a brand-spanking-new copy of Android Studio, to make it work for compiling the FLIR One SDK sample app. So somebody, PLEASE help me. Please write me a tutorial, that if I follow all the steps correctly is GUARANTIED to cause the resulting APK file to be a valid APK file.
