Can't compile MediaRouteButton into project

Question

I'm doing in Movie project with CastButton, I completed a sample and this worked perfect. But when I'm doing in true project I have a problem. I imported compile into my grande file, but when I create MediaRouteButton I have I got error, I tried many ways but I can't fix it, so I now I really need a help: This is: compile file:

compile 'com.android.support:appcompat-v7:25.0.0'
    compile 'com.android.support:mediarouter-v7:25.0.0'
    compile 'com.googlecode.android-query:android-query:0.25.9'
    compile 'com.google.android.gms:play-services-cast-framework:10.2.0'

this is logcat:

How can I fix it?

Based from this thread, you are getting that error because of the following reasons:

In your gradle build file, maybe your app is targeting and compiling with the beta version of android that is still in development with:
compileSdkVersion 'android-L'
buildToolsVersion '20'
as well as
minSdkVersion 20
targetSdkVersion 20
First thing to note is that this app will not run correctly (at this time) on any device without android-L flashed to it.

Additional reference: java.lang.NoClassDefFoundError: Failed resolution of: Landroid/support/v4/os/BuildCompat

Check your classpath contains that jar (AppCompat), if your classpath doesn't contain the jar then just add that class in your classpath.

Hope this helps!

compileSdkVersion 23 buildToolsVersion "25.0.3" minSdkVersion.apiLevel 18 targetSdkVersion.apiLevel 23 I'm using it — Evan Ngo, Jun 13 '17 at 03:56
