Android N（预览版）在“构建目标”下指的是什么

Question

I am using intellij idea for android development. I presume it is the same thing as android studio. I imported an existing android project into intellij idea, using the following instructions:

https://www.jetbrains.com/help/idea/2016.1/importing-an-existing-android-project.html?origin=old_help

Under step 8) in the ordered list, I specified the Java SDK 1.8 and continued the import. Now when I launched intellij idea, I got the following error:

Android SDK is not configured for module "X" or corrupted

So I opened the project structure. I went to Platform Settings > SDKs. Since I already specified the Java SDK during the import, now I need to specify the Android SDK. I clicked the + sign and specified Android SDK. Then I went to the root directory of my SDK install (android-sdk-macosx) and selected that folder.

Now I get a little popup that says:

Create New Android SDK
Java SDK: 1.8 
Build target: Android N (Preview)

I have the latest Android SDK (Android 6.0). But I also have Android SDK 4.1.2 to work on older devices. But I also use google maps so I have also Google APIs 6.0 and 4.1.2 respectively.

In other words, I have 5 options for Build target:

Android N (Preview)
Android 6.0
Android 4.1.2
Google APIs 6.0
Google APIS 4.1.2

Which one do I select?

Answer 1

But I also use google maps so I have also Google APIs 6.0 and 4.1.2 respectively

Unless you are using the long-since-deprecated Maps V1 API, you do not need those Google APIs build targets. Maps V2, the current edition of the Android integration for Google Maps, can be built using a normal build target and the appropriate Play Services SDK.

Which one do I select?

Android 6.0, most likely. That equates to what in Android Studio would be a compileSdkVersion of 23.

Choosing 'N' limits you to testing with the N Developer Preview. Since you have not mentioned this, I am assuming that this is not your objective.
