Your build.gradle version is simply the wrong one.

Follow these instructions to fix that:

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

Maybe you can try one of the following solutions:

<ol>
<li>delete <code>.gradle</code> folder under the project</li>
<li>if the project is imported from Eclipse, or it is an old project

<ol>
<li>upgrade <code>minSdkVersion</code> in <code>app/build.gradle</code>, eg. 14 or 16, which is greater than 8 !</li>
<li>remove the <code>minSdkVersion</code> &amp; <code>targetSdkVersion</code> configuration in <code>AndroidManifest.xml</code> !</li>
</ol></li>
<li>import <code>com.android.support:appcompat-v7</code> library in <code>app/build.gradle</code></li>
<li>upgrade your Android Studio to the latest version</li>
<li>if it still doesn't work, maybe you can:

<ol>
<li>restart Android Studio</li>
<li>delete the project in Android Studio and reimport it.</li>

My theme parent was <code>android:Theme.Light</code> and I wanted to change it to the AppCompat version. I mistakenly changed it to <code>android:Theme.AppCompat.Light</code>, but instead I needed to change it to <code>Theme.AppCompat.Light</code>.

Try to do Refactor > Migrate to AppCompat....
It worked for me

blocks|key|1651398|text|我的修复方法是删除项目根目录中的.gradle文件夹，然后单击文件并单击“同步”。从那以后一切都正常了。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1651399|entityMap^0|0^^$0|@$1|2|3|4|5|6|7|D|8|@]|9|@]|A|$]]|$1|B|3|-4|5|6|7|E|8|@]|9|@]|A|$]]]|C|$]]

The fix for me was to delete the .gradle folder in my project root, then click file and click "Synchronize". everything worked after that.

blocks|key|1654076|text|只需在build.gradle+(即app.gradle+)中再次删除并添加以下行，并对其进行同步：|type|unstyled|depth|inlineStyleRanges|offset|length|style|BOLD|entityRanges|data|1654077|implementation+'com.android.support:appcompat-v7:26.1.0'

Just remove and add this below lines again in build.gradle i.e. app.gradle and sync it:

<pre><code>implementation 'com.android.support:appcompat-v7:26.1.0'
implementation 'com.android.support:design:26.1.0'
implementation 'com.android.support:support-v4:26.1.0'
</code></pre>

as per your android version.........

Theme.AppCompat.Light.DarkActionBar is not compiling in styles.xml. I have added <code>compile 'com.android.support:appcompat-v7:25.1.0'</code> in app module's 
<code>build.gradle</code>. <a href="https://i.stack.imgur.com/AQjky.png" rel="noreferrer"><img src="https://i.stack.imgur.com/AQjky.png" alt="Theme Error"></a>

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

<pre><code>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"
 }
</code></pre>

Theme.AppCompat.Light.DarkActionBar没有在styles.xml中编译。我在应用模块的build.gradle中添加了build.gradle。​我在谷歌搜索过解决方案。其中很多是关于更改Project的build.gradle.Still中的类路径的，它显示了相同的错误。build.gradledependencies {    compile 'com.andr
