Can't compile MediaRouteButton into project - chromecast

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'

How can I fix it?

Answer 1

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!
