“android list targets 无target显示” 的解决方法。

If you're getting started with the Android SDK and
encounter an error message which says "Error: Target id is not valid.
Use 'android list targets' to get the target ids'" here's how to solve
it...

While you're developing an Android application you'll need to create
an Android Virtual Device or AVD, which allows you to test your
application before you let it loose on a real 'phone.

The docs
tell you to run the following command: android create avd --target 2
--name my_avd However, this gave me the following error "Error: Target
id is not valid. Use 'android list targets' to get the target ids."

Running
android list targets listed no available targets. This is because the
SDK needs some further set-up work to tell it to fetch sources before
you can use it.

To get around this problem type android in your
terminal. Then click Available sources > check the box and click
install selected. It will then go off and download all of the SDK
packages via an https repository server at google.com/android.

Now re-run android create avd --target 2 --name my_avd and it should allow you to create the AVD and map it to a target.
