> Manifest merger failed : Attribute meta-data#android.support.VERSION@value value=(26.0.0-alpha1) from [com.android.support:appcompat-v7:26.0.0-alpha1] AndroidManifest.xml:27:9-38
is also present at [com.android.support:cardview-v7:25.3.1] AndroidManifest.xml:24:9-31 value=(25.3.1).
Suggestion: add 'tools:replace="android:value"' to element at AndroidManifest.xml:25:5-27:41 to override.
解决办法 1：replacecompile 'com.android.support:recyclerview-v7:+'bycompile 'com.android.support:recyclerview-v7:25.3.1'
解决方法二 在build.gradle（module.app）中加
configurations.all {
resolutionStrategy.eachDependency { DependencyResolveDetails details ->
defrequested = details.requested
if(requested.group =='com.android.support') {
if(!requested.name.startsWith("multidex")) {
details.useVersion'25.3.0'
}
}
}
}
