10 years ago Preparing your application for release is a multi-step process that involves the following tasks:
Configuring your application for release. At a minimum you need to remove Log calls and remove the android:debuggable attribute from your manifest file. You should also provide values for the android:versionCode and android:versionName attributes, which are located in the
element. You may also have to configure several other settings to meet Google Play requirements or accomodate whatever method you're using to release your application. Building and signing a release version of your application. The Android Development Tools (ADT) plugin and the Ant build script that are provided with the >Android SDK tools provide everything you need to build and sign a release version of your application. Testing the release version of your application. Before you distribute your application, you should thoroughly test the release version on at least one target handset device and one target tablet device. Updating application resources for release. You need to be sure that all application resources such as multimedia files and graphics are updated and included with your application or staged on the proper production servers. Preparing remote servers and services that your application depends on. If your application depends on external servers or services, you need to be sure they are secure and production ready.
We should take a brief run through this official launch checklist before throwing our app up on the Play Store:
