Execution failed for task :app:processDebugManifest Android Studio 2.3.3

Question

I'm getting a compile error after adding CardView and RecyclerView dependencies, I've checked every post but no one seems to solve this case.

Error:

Error:Execution failed for task ':app:processDebugManifest'. Manifest merger failed : Attribute meta-data#android.support.VERSION@value value=(25.3.1) from [com.android.support:appcompat-v7:25.3.1] AndroidManifest.xml:27:9-31 is also present at [com.android.support:cardview-v7:26.0.0-alpha1] AndroidManifest.xml:24:9-38 value=(26.0.0-alpha1). Suggestion: add 'tools:replace="android:value"' to element at AndroidManifest.xml:25:5-27:34 to override.

My Build.Gradle:

apply plugin: 'com.android.application'

android {
    compileSdkVersion 25
    buildToolsVersion "26.0.0"
    defaultConfig {
        applicationId "com.soft.kukito.cardviewprueba"
        minSdkVersion 21
        targetSdkVersion 25
        versionCode 1
        versionName "1.0"
        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}

dependencies {
    compile fileTree(include: ['*.jar'], dir: 'libs')
    androidTestCompile('com.android.support.test.espresso:espresso-core:2.2.2', {
        exclude group: 'com.android.support', module: 'support-annotations'
    })
    compile 'com.android.support:appcompat-v7:25.3.1'
    compile 'com.android.support.constraint:constraint-layout:1.0.2'
    testCompile 'junit:junit:4.12'
    compile 'com.android.support:cardview-v7:26.0.0-alpha1'
    compile 'com.android.support:recyclerview-v7:26.0.0-alpha1'
}

Thank everyone for answering.

Solution

You need to use the same android support library version. You need to use support library 26.0.0-alpha1 version. So change the following:

compile 'com.android.support:appcompat-v7:25.3.1'

to

compile 'com.android.support:appcompat-v7:26.0.0-alpha1'

You also need to change the compileSdkVersion and targetSdkVersion to version 26.

If i change that, would it works for example in Loollipop after compile?

[ישו אוהב אותך]

it will support the minimum sdk that you set in minSdkVersion. In your case, you use minSdkVersion 21 and targetSdkVersion 25 which telling the Android Studio to build the project to support Android Lollipop (5.0) to Android 7.1
