Where are the Android API Demos?

For API 18 its on sdk/samples/android-18/legacy/ApiDemos and for others its on sdk/samples/android-x/ApiDemos

Hi dey are available in the folder android-sdk/samples/apidemos

android.googlesource.com

https://android.googlesource.com/platform/development is the official repository that contains the "API Demos" app at path samples/apidemos.

That repository is mirrored at: https://github.com/android/platform_development

${SDK_DIR}/samples/ also contains many other interesting sample apps.

I was also maintaining some unofficial demos which are more minimal than the official ones: https://github.com/cirosantilli/android-cheat
