Cannot resolve symbol 'Theme.AppCompat.Light.DarkActionBar' in styles.xml

Question

Theme.AppCompat.Light.DarkActionBar is not compiling in styles.xml. I have added compile 'com.android.support:appcompat-v7:25.1.0' in app module's build.gradle.

I have searched for solution in google. A lot of them are about changing the classpath in Project's build.gradle.Still its showing the same error.

build.gradle

dependencies {
    compile 'com.android.support:appcompat-v7:25.1.0'
    compile 'com.android.support:design:25.1.0'
    compile 'com.android.support:support-annotations:25.1.0'
    compile 'com.android.support:cardview-v7:25.1.0'
    compile 'com.android.support:recyclerview-v7:25.1.0'
    //    compile 'ch.acra:acra:4.5.0'

    testCompile 'junit:junit:4.12'
}

android {
    compileSdkVersion 25
    buildToolsVersion '25.0.2'

    defaultConfig {
        minSdkVersion 14
        targetSdkVersion 25
        versionCode = 146
        versionName = "0.6.65"
    }

Your build.gradle version is simply the wrong one.

Follow these instructions to fix that:

In Android studio, go to the Gradle scripts section in the left panel.
Find the file: build.gradle(Project:{your_project_name})
In that file look at the line com.android.tools.build:gradle
Check that the version match with your android studio version (for instance 2.3.3). This implies that com.android.tools.build:gradle:2.3.3 and And an Android studio distribution with 2.3.3 as version.
Validate the versions are the same. If it's not the case, make sure they match.
Rebuild the project and everything is fine!

<style name="Theme.Base.MyTheme" parent="Theme.AppCompat.Light.NoActionBar">

In case when clean/rebuild not work, just delete .gradle directory in your project root. And sync project with gradle again.

This issue is caused when you mix cache of your support libraries.

I have noticed that all themes available with the prefix @android:style/ can be used. So, I have solved this issue by replacing

Theme.AppCompat.Light.DarkActionBar

with

@android:style/Theme.DeviceDefault.Light.DarkActionBar

That is replacing one theme (shipped with your app) with another (shipped with your OS), this is not a fix – charlag Oct 04 '21 at 15:17

I had the exact same problem, what fixed it for me was retrograding gradle plugin:

buildscript {
    repositories {
        jcenter()
    }
    dependencies {
        //classpath 'com.android.tools.build:gradle:2.3.1'
        classpath 'com.android.tools.build:gradle:2.2.3'
    }
}

Followed by a project sync with gradle files to clear the problem.

Maybe you can try one of the following solutions:

delete .gradle folder under the project
if the project is imported from Eclipse, or it is an old project
1. upgrade minSdkVersion in app/build.gradle, eg. 14 or 16, which is greater than 8 !
2. remove the minSdkVersion & targetSdkVersion configuration in AndroidManifest.xml !
import com.android.support:appcompat-v7 library in app/build.gradle
upgrade your Android Studio to the latest version
if it still doesn't work, maybe you can:
1. restart Android Studio
2. delete the project in Android Studio and reimport it.

Thanks. Deleting `.gradle` helped to compile a project. For me another solution helped: https://stackoverflow.com/a/52094111/2914140. — CoolMind, Sep 02 '18 at 16:25

Check your build.gradle file , set compileSdkVersion to 25 . Following gradle is working for me with appcompat-v7:25.1.0'

android {
    compileSdkVersion 25
    buildToolsVersion "25.0.0"
    defaultConfig {
        applicationId "xxx.xx.xxxxx"
        minSdkVersion 16
        targetSdkVersion 21
        versionCode 26
        versionName "3.16"
        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
    }
    buildTypes {
        release {
            minifyEnabled true
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}

dependencies {
    //compile 'com.google.firebase:firebase-messaging:9.0.1'
    compile 'com.android.support:appcompat-v7:25.1.0'

I did everything as has been suggested in the accepted answer and it didn't help. Then I did everything as has been suggested in this answer: Android studio cannot find Theme.AppCompat.Light.DarkActionBar (enabled all components in Repository) and it didn't help either.

The issue has been only resolved after clicking on "Synchronized" in File menu. I'm running Android 3.0.1 on Mac.

I had the same issue in Android 3.0.1, tried doing "Synchronize", Resysnching gradle etc but nothing helped, I then found that adding

implementation 'com.android.support:design:27.0.2' line fixed the issue

dependencies {
    implementation fileTree(dir: 'libs', include: ['*.jar'])
    implementation"org.jetbrains.kotlin:kotlin-stdlib-jre7:$kotlin_version"
    implementation 'com.android.support:support-compat:27.0.2'

This works for me.

Close android studio project.
Remove project from recent.
Go to project directory and delete ".gradle" directory.
Open project from option "Open an existing Android Studio Project".

I have this problem and it is because in my new style and it is because when I declare a new style I put "Theme.AppCompat.Light.NoActionBar" in the name instead of parent. I change from :

<style name="Theme.AppCompat.Light.NoActionBar" />

to

<style name="ThisTheme" parent="Theme.AppCompat.Light.NoActionBar"/>

I tried many solutions, including deleting of .gradle folder (yes, it works, a project becomes compilable), but red themes didn't disappear.

This advice helped:

Go into the .idea directory
Remove caches and libraries directories
File -> Invalidate Caches -> Restart

This solution worked for me

Close project (File> Close Project)
Import / Re-Open project again (NOT from Recent)

Error should be resolved now.

If that fails, try below-

Open build.gradle, remove appcompact-v7 dependency and sync project.
Add appcompact-v7 dependency and sync.

Issue solved!

Thanks for your answer, but please explain why your solution solves the problem. Also the support libraries posted are for level 26, but the user is compiling against 25. But there is no real warning of the consequences. – Elletlar Jul 21 '18 at 10:06
Should we downgrade support libraries? – CoolMind Aug 30 '18 at 09:16
