Error:Execution failed for task ‘:hb_cippo:processDebugManifest’.

Manifest merger failed : Attribute meta-data#android.support.VERSION@value value=(25.3.0) from [com.android.support:design:25.3.0] AndroidManifest.xml:27:9-31
is also present at [com.android.support:appcompat-v7:26.0.0-alpha1] AndroidManifest.xml:27:9-38 value=(26.0.0-alpha1).
Suggestion: add ‘tools:replace=”android:value”’ to element at AndroidManifest.xml:25:5-27:34 to override.

在引入library后报冲突，原因是引入的library的v7包和原工程的不一样
把compile ‘com.android.support:appcompat-v7:26.0.0-alpha1’
改成
compile ‘com.android.support:appcompat-v7:25.3.0’
就好了
