Android Build Failed

Hello Eddy,

I am trying NativeScript and wanted to build your showcase. However, I got the following error message when building for android (with: `tns run android`).

`~/nativescript-pluginshowcase/platforms/android/app/src/main/AndroidManifest.xml:27:9-31 Error:
Attribute meta-data#android.support.VERSION@value value=(25.4.0) from [com.android.support:design:25.3.1] AndroidManifest.xml:27:9-31
is also present at [com.android.support:support-v4:26.1.0] AndroidManifest.xml:28:13-35 value=(26.1.0).
Suggestion: add 'tools:replace="android:value"' to element at AndroidManifest.xml:26:9-28:38 to override.`

`FAILURE: Build failed with an exception.`

`* What went wrong:
Execution failed for task ':app:processDebugManifest'.`
`> Manifest merger failed : Attribute meta-data#android.support.VERSION@value value=(25.4.0) from [com.android.support:design:25.3.1] AndroidManifest.xml:27:9-31
is also present at [com.android.support:support-v4:26.1.0] AndroidManifest.xml:28:13-35 value=(26.1.0).
Suggestion: add 'tools:replace="android:value"' to element at AndroidManifest.xml:26:9-28:38 to override.
`

As I am new to NativeScript, I obviously did something wrong, but can't figure out what...

Thanks in advance for your reply.
