Menu
I implemented the PlacePicker.IntentBuilder UI into my application. For the longest it worked with no problem but now as soon as the UI appears, it closes and im not sure why. The crazy thing is looking at the logcat it doesn't crash or cause any exceptions so I don't know what the issue is. This is the class that creates and calls it.
