Android Device Not Visible In Eclipse using USB cable
I wanted to connect a Galaxy Tablet by Samsung to my Eclipse Android SDK with the USB cable. I downloaded the appropriate drivers, followed all of the instructions including setting the tablet in Application debug mode, and still nothing. Nada! Zilch! I thought that maybe I had the wrong driver, so I uninstalled the driver, went to the Samsung site, and got the driver again and installed it. Nothing! Crapola!
I have more than one Android app on the go, because the app that I am developing is quite complex, so I prototype each function as a separate project to make sure that I have the Java code right. I went to another project and look at the run configs, and I could see the device in the run configuration menu. It ran perfectly. So, WTH?
After much wailing and gnashing of teeth, I decided to examine LogCat very closely. It said it couldn't find a compatible minimum SDK version device attached. Well, I did know where it was specified and that was in the AndroidManifest.xml. So I went there and sure enough, I had accidentally changed the minSdkVersion to 17, instead of 8. The 17 number was for the targetSdkVersion.
When I changed the minSdkVersion back to 8, I could see the USB connected device.
Hope this helps someone.
