如何使用Gradle工具在Android中使用不同的数据库构建不同的APK文件？

Question

We have a platform to read poetry with a SQLITE Database say SHAKESPEARE.DB . We also have another poetry say Wordsworth.DB. So for each poetry database we want to create a separate application like Shakespeare.apk and wordsworth.apk.

During build we want to mention the Database and mention the name of the APK.

How do we Change Database during android build through gradle and deploy different APK's
I would want to Create and Deploy Database specific APK using Gradle ?

Answer 1

Step #1: Use a consistent means of embedding the database in the app. For this answer, I will assume that you are using SQLiteAssetHelper , with the database packaged as words.db in assets/ .

Step #2: Create two product flavors for your app in your app/ module's build.gradle file. For this answer, I will call these flavors vanilla and chocolate :

productFlavors {
    vanilla {
        applicationId "com.commonsware.android.gradle.hello.vanilla"
    }

    chocolate {
        applicationId "com.commonsware.android.gradle.hello.chocolate"
    }
}

(replace the applicationId values with ones more relevant to your project)

Step #3: Create a sourceset for each flavor ( app/src/vanilla , app/src/chocolate/ ).

Step #4: Put a different words.db in assets/ of the flavor ( app/src/vanilla/assets/words.db , app/src/chocolate/assets/words.db ).

Now, when you build vanilla , it will use the vanilla edition of words.db . When you build chocolate , it will use the chocolate edition of words.db . No Java code changes are required. You can also put different resources in those flavor-specific sourcesets, for different icons, labels, etc. Because you have different applicationId values, both flavors can be installed on your test devices at the same time, and both flavors can be distributed through app distribution channels like the Play store.
