Android Build Failed

[SK0RM]

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 <meta-data> 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 <meta-data> 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.

After several try, this fixes it:

dependencies {
    configurations.all {
      resolutionStrategy.eachDependency {
        DependencyResolveDetails details ->
          def requested = details.requested
          if (requested.group == 'com.android.support') {
            if (!requested.name.startsWith("multidex")) {
              details.useVersion '25.4.0'
            }
          }
      }
    }
  }

If you could explain to me why is this needed, I would be really grateful.
