When I add third party dependencies I get a manifest merger fail, what should I do to fix this?

Question

Error:Execution failed for task ':app:processDebugManifest'.

Manifest merger failed : Attribute meta-data#android.support.VERSION@value value=(26.0.2) from [com.android.support:design:26.0.2] AndroidManifest.xml:28:13-35 is also present at [com.android.support:support-v13:26.0.1] AndroidManifest.xml:28:13-35 value=(26.0.1). Suggestion: add 'tools:replace="android:value"' to element at AndroidManifest.xml:26:9-28:38 to override. apply plugin: 'com.android.application'

app.gradle file

android {
    compileSdkVersion 26
    buildToolsVersion "26.0.1"
    defaultConfig {
        applicationId "com.dharquissandas.budget"

    }

android manifest

        android:label="@string/app_name"

        android:supportsRtl="true"
        android:theme="@style/AppTheme">
        <activity
            android:name=".MainActivity"
            android:label="@string/app_name"
            android:theme="@style/AppTheme.NoActionBar">
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
        <activity
            android:name=".add_expense"
            android:label="@string/title_activity_add_expense"
            android:theme="@style/AppTheme.NoActionBar" />
        <activity
            android:name=".add_income"
            android:label="@string/title_activity_add_income"
            android:theme="@style/AppTheme.NoActionBar" />
    </application>

</manifest>

This was working and then suddenly it stopped working when I wanted to work on the app again. What should I do to fix this error?

Answer 1

configurations.all {
    resolutionStrategy.eachDependency { DependencyResolveDetails details ->
        def requested = details.requested
        if (requested.group == 'com.android.support') {
            if (!requested.name.startsWith("multidex")) {
                details.useVersion '26.0.1'
            }
        }
    }
}

This helped me, add this to your build.gradle and make sure you are using the same versions as '26.0.1'.
