Error: Please select Android SDK

Question

My Android Studio version is 2.1 preview. I'm running my project using Google APIs, Android 17, rev 4 (API 17).

I'm having 1 pop-up error while debugging app.

[Information: Image to show my pop-up errror. Click to show this.][1]

I never met error like this earlier. How can I resolve this?

Updated:

I often meet error like this:

error: diamond operator is not supported in -source 1.6
(use -source 7 or higher to enable diamond operator

I waas trying to do research on this. I tried but it never worked out. When does this error come and how can I resolve it?

Thanks.

It is not an error. Its just Android Studio trying to figure out what you want to debug. So in your case the "app" module. Have you done a gradle build through? Pushing this: . Gradle should set it up so you dont have to choose debug target.

EDIT: This icon is different on Android Studio 3.0, is called "Sync Project with Gradle Files".

Open Android Studio preference-> search for "SDK" -> edit Android SDK Location point it to your sdk android folder.

UPDATE

For resolve this error

error: diamond operator is not supported in -source 1.6
(use -source 7 or higher to enable diamond operator

Download jdk 1.7 and open Module Setting -> SDK Location -> edit JDK Location point it to jdk 1.7 home foler.

On new Android Studio; Open app's module settings with right click, Select 'app' from left sidebar, Change 'Compile Sdk Version' na 'Build Tools Version' as whatever your compileSdkVersion & buildToolsVersion are on build.gradle, Click OK, that's it.
