I\'m attempting to transition from Eclipse to Android Studio today. I generated the Gradle build files in Eclipse and imported into Android Studio. I changed my preferences
I had same problem and I was able fix that problem.
My error was:
Waiting for device. USB device not found
This happens when I was using SONY XPERIA Tipo Dual and Samsung Galaxy Core Duos i8262.
I solved problem in both devices.
SONY XPERIA Tipo Dual
Install "SONY PC Companion" which is automatically detect your driver.
Run your app again. You can see your app is running in your device.
Samsung Galaxy Core Duos i8262
Install USB drive. You can find it here. Direct Url to download
Run your app again. You can see that still you are getting same error. Go to notification section. You can see that, phone is connected as a media device(Media device(MTP)). You need to change it as "Camera (PTP)" by touching notification.
Run your app again. Wow. It works...
