Gradle dependencies for different api levels

Question

Unfortunately, I have to support Android 2.3, but I want to use a third-party ui widget with min-sdk 14 (Android 4.0).

Is there a way to enable dependency using min-sdk 14?

In the code, I would check Build.SDK_INT to determine whether to use the ui widget with a minimum SDK of 14 or fallback user interface widgets.

Answer 1

This is not possible ... If you have a dependency, then inside your compilation. inside your apk. You can choose whether you want to use this third-party library with if (SDK_INT), but lib will be compiled in your application as well.

Answer 2

Unfortunately, since you must include the dependency, it will always be compiled into your project.

You can split your project into separate projects. If you created something like BaseApp and IceCreamSandwichApp , you could set different minSdkVersions for each along with a different set of dependencies.

Thus, you must have modules in your application:

 your-app/BaseApp 

and

 your-app/IceCreamSandwichApp 

And your gradle files look something like this:

your-app / settings.gradle

 include ':BaseApp', ':GingerbreadApp' 

your-app / BaseApp / build.gradle

 android { buildToolsVersion '22.0.1' defaultConfig { minSdkVersion 9 compileSdkVersion 21 targetSdkVersion 21 } ... dependencies { compile fileTree(dir: 'libs', include: ['*.jar']) } } 

your-app / IceCreamSandwichApp / build.gradle

 android { buildToolsVersion '22.0.1' defaultConfig { minSdkVersion 14 compileSdkVersion 21 targetSdkVersion 21 } ... dependencies { compile fileTree(dir: 'libs', include: ['*.jar']) compile project(":BaseApp") compile 'the.third.party:lib:here:1.0.0' } }
