today I wanted to try some sample app on my new fire tv. So I got Android Studio and the fire tv sdk installed. I build and UIWidgetsSample project. Connecting to the fire tv was easy with adb thanks to a nice help page
https://developer.amazon.com/appsandservices/solutions/devices/fire-tv/docs/installing-and-running-your-app. Now here is my problem: I can't start the application. It is on the device. I can see it in settings>applications>manage all installed applications. When I try to start nothing happens. It seems to exit immediately. Same result if I try to start it on a adb shell. Any idea? Perhaps some security settings? I turned adb debugging on.
today I tried again and success! Actually I not sure why, here is what I did: 1) developer options - activated apps from unknown sources 2) signed apk files - yesterday I used android-studio and I am not sure if it created a signed apk. So I switched to eclipse and simply created a signed apk from my own keystore. And now it somehow worked:) There is a nice command 'adb logcat'. Lots of output, but nice debugging info.
