This is my build.gradle.I am facing this issue. All com.android.support libraries must use the exact same version. Found versions 26.0.1-alpha1, ,23.0.0. I am trying to find out the error, did some research as well, but I was not able to figure out where the error is. Please help me regarding the same.

Answer 1

From your build file I can see you didn't include the version 23.0.0. That mean some library you included depends on it.

Run

./gradlew app:dependencies --configuration compile

to list the dependencies. From the graph you can see which library is pulling it transitively. Then you can exclude it:

dependencies {
  compile ('<DEPENDENCY>') {
    exclude group: "<GROUP>", module: "<MODULE>"
  }
}
