AVD Manager

I just started the Android track and I'm already stuck. When I head over to AVD Manager to try to create a new one, I'm required to give more information than AVD name and Target as instructed by the video. What do I do?

Besides the AVD name and target (API level), you will also have to choose a device. This can either be a specific one that you have (for me only stock google android devices are available), or a generic one that specifies the size of the screen, resolution and density. For example there is a big difference in how an app would be displayed on these two devices:

  • 4.7" WXGA (1280 x 720: xhdpi)
  • 3.2" QVGA (320 x 480: mdpi)

I would also recommend adding a value in the SD card field if you think your app might store data on the device. This is not really something to worry about too much as a beginning Android developer. However in my experience I found that launching the Android emulator can be really slow sometimes. So you definitely want to enable the 'Use Host GPU' option to speed the launch time up a bit.

Hi Matthew, You did set the Android SDK location in Eclipse's Preferences panel, correct? Preferences -> Android

Alternately, it could be a permissions problem with the .android/avd directory. Which operating system are you running? This page on stackoverflow.com might help you with this permissions problem.
