While trying to clone Android O sample from github, project can't able to sync and give below error. Android studio give package unavailable, which can't able to install missing platform (android o).
I am using android studio 2.3 and cloning android o example: https://developer.android.com/preview/o-samples.html#nc
Can any one suggest, how can I able to run cloned example?
To add the Android O items to Android Studio 2.3, I had to temporarily switch to the Canary channel in Android Studio:
Then, in the SDK Manager, I could download the O Developer Preview items:
...along with the 26-rc1 build tools, platform tools, and emulator:
That should get you past your current problems.
That project is messed up, in that it refers to a @mipmap/ic_launcher that does not exist. You need to get rid of android:icon="@mipmap/ic_launcher" from the <application> element of Application/src/main/AndroidManifest.xml, after which the app appears to work.
