Android Studio 3.0.1的问题

Question

Hey people,

I'm having this problem about a few hours. I already tried with Invalider cache/Restart but didn't work also I downloaded the last versions of the SDK Tools. Anyone knows how to solve it?

This is my gradle

Also, I'm having this issue too

Thanks in advance.

Answer 1

Please add constraint-layout dependency also.

compile 'com.android.support.constraint:constraint-layout:1.1.0-beta3'

and try adding AppCompact support in dependency.

implementation 'com.android.support:appcompat-v7:27.0.0'

** Please change version names according to your build.

Answer 2

In your app level build.gradle file, specify:

dependencies {
    compile 'com.android.support:recyclerview-v7:26.0.3'
    compile 'com.android.support:design:26.0.3'
    ...
}

Answer 3

布局中的渲染为26，而在gradle中，targetSdkVersion为25
