Error in support lib after room persistence

问题

I'm trying to use the library room persistence, with SDK min 16. After I add room persistence in gradle I get the error below: if I take the last 2 lines of depency (from the lib room) compile normal. Help!

 error: cannot access ActivityCompatApi23
public class MainActivity extends AppCompatActivity
       ^
  class file for android.support.v4.app.ActivityCompatApi23 not found

my gradle is basic:

    compileSdkVersion 25

    defaultConfig {

        minSdkVersion 16
        targetSdkVersion 25

回答1:

I added the issue in Google's Issue Tracker and they replied:

Room depends on 26.1 of support library, which is probably why it is broken because SupportLibrary does not promise interop between versions.

and added:

You cannot fix and match support library versions. Please match whatever highest version you end up needing by your dependencies.

Then the problem is resolved, Room + lib is only supported with version 26.1 + of the library.

My final gradle:

compileSdkVersion 26

    defaultConfig {
        applicationId "com.br.xxxx"

        minSdkVersion 16
        targetSdkVersion 26
        versionCode 45
        versionName "3.0.2"
    }

...

         maven { url 'https://maven.fabric.io/public' }
