问题 first time learning coding language here.. I am struggling in many parts of Java, but I am slowly learning. I was making an app and had to show dynamically updating text.

问题 Prior to Android Studio 1.5, the device chooser was shown upon Gradle Build completion. This allowed to use build time to physically configure devices, make any last minute changes or to ensure that devices were actually connected at the time of install.
