Preview stopped working after update

Question

I Work in a Android Project and, after Adroid Studio 3.0 update, the problems come around.

The preview of my activities stop showing data, the project's still building and I can install on emulator/Phone, but I couldnt' see all the changes that I made in XML layout, here's the error message:

Failed to load AppCompat ActionBar with unknown error.

and thoses errors:

- android.support.v7.widget.AppCompatImageView (Open Class, Show Exception, Clear Cache)
- android.support.design.widget.CoordinatorLayout (Open Class, Show Exception, Clear Cache)
- android.support.v7.widget.RecyclerView (Open Class, Show Exception, Clear Cache)
- android.support.design.widget.FloatingActionButton (Open Class, Show Exception, Clear Cache)
- android.support.v7.widget.Toolbar (Open Class, Show Exception, Clear Cache)
- android.support.v7.widget.AppCompatTextView (Open Class, Show Exception, Clear Cache)
- android.support.v7.widget.ActionBarContextView (Open Class, Show Exception, Clear Cache)
- android.support.v7.app.WindowDecorActionBar (Open Class, Show Exception, Clear Cache)
- android.support.v7.widget.ActionBarOverlayLayout (Open Class, Show Exception, Clear Cache)

I readed this link here and it seems to be a Gradle Problem, I tried to restored a older version of Gradle in my git repo, but the problems continues, here's my gradle:

apply plugin: 'com.android.application'

android {
    compileSdkVersion 23
    buildToolsVersion '26.0.2'

    lintOptions {
        checkReleaseBuilds false
        abortOnError false
    }

    defaultConfig {
        applicationId "br.com.golfetto.golfettomobile"

EDIT:

Just to clarify, i already tried to change the theme in styles.xml, here's the change:

<style name="AppTheme" parent="Base.Theme.AppCompat.Light.DarkActionBar">
    <!-- Customize your theme here. -->
    <item name="colorPrimary">@color/colorPrimary</item>
    <item name="colorPrimaryDark">@color/colorPrimaryDark</item>
    <item name="colorAccent">@color/colorAccent</item>
</style>

for those how help, I appreciate

update your support library versions to 26.0.0 or higher. And Rebuild the project — Sudheesh R, Nov 08 '17 at 12:48
@SudheeshR could you please be more specific, which support library ? — Guilherme Golfetto, Nov 08 '17 at 12:52
change your all 'com.android.support' libs to latest, that'll fix those errors. — Sudheesh R, Nov 08 '17 at 12:54
FYI: please refer here, newest versions: https://developer.android.com/topic/libraries/support-library/packages.html — Sudheesh R, Nov 08 '17 at 12:56
and also don't forget to change your compileSdkVersion and buildToolsVersion compatible to the support libraries. — Sudheesh R, Nov 08 '17 at 13:04

You need to use the same version of compileSdkVersion, buildToolsVersion, targetSdkVersion, and Support Library in your build.gradle. You need to change to something like this:

apply plugin: 'com.android.application'

android {
    compileSdkVersion 26
    buildToolsVersion '26.0.2'

    lintOptions {
        checkReleaseBuilds false
        abortOnError false
    }

    defaultConfig {
        applicationId "br.com.golfetto.golfettomobile"
        minSdkVersion 15
        targetSdkVersion 26
        versionCode 1
        versionName "2017.11.07"
        multiDexEnabled true
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
    dexOptions { javaMaxHeapSize "4g" }
}
dependencies {
    ...
    compile 'com.android.support:appcompat-v7:26.1.0'
    compile 'com.android.support:design:26.1.0'
    compile 'com.android.support:support-v4:26.1.0'
    compile 'com.android.support:cardview-v7:26.1.0'
    compile 'com.android.support:recyclerview-v7:26.1.0'
}

Read an article about it at Picking your compileSdkVersion, minSdkVersion, and targetSdkVersion

You're welcome ;). And don't forget to use the same version of `com.google.firebase` — ישו אוהב אותך, Nov 08 '17 at 15:14
