Android Market is a service that makes it easy for users to find and download Android applications to their Android-powered devices, such as mobile phones and tablet PC's, either directly from their device or from the Android Market web site (market.android.com). As a developer, you can use Android Market to distribute all your amazing applications to users all around the world. But but what is the process involved?
Android Market Publish
Droid Apps and how to publish them to Android Market
Make sure you've done all the testing on you need to do and that you've properly compiled your app as outlined in the Android Developers Guide. Now, the nest thing you need to do is create a Developer profile on the Android Market http://market.android.com/publish). From the Android Market site, sign with your Google Account. If you don't have a Google Account, you need to pop over to Google and register one. To create the Developer profile, you'll need to provide your name, email, website URL, and phone number. A $25 registration fee is required, but it's a one-time fee, and all developers need to pay it, even if you are publishing a free app. You can pay using credit card or Google Checkout.
You can publish your application using a hosted service such as Android Market or through a web server. Before you publish, make sure you have prepared your application properly. Android Market makes it easy for users of Android-powered devices to see and download your application.
If you plan to publish your application on Android Market, you must make sure that it meets the requirements listed below, which are enforced by the Market server when you upload the application.
Requirements enforced by the Android Market server:
- Your application must be signed with a cryptographic private key whose validity period ends after 22 October 2033.
- Your application must define both an android:versionCode and an android:versionName attribute in the element of its manifest file. The server uses the android:versionCode as the basis for identifying the application internally and handling updates, and it displays the android:versionName to users as the application's version.
- Your application must define both an android:icon and an android:label attribute in the element of its manifest file.
- You must agree to the Android Market Developer Distribution Agreement.
- You must prepare to publish by compiling the required .apk file that is signed with your private release key.
Then What?
Once the App is uploaded, you should see in the Android Market in a matter of moments. You can publish your application and allow users to install it any way you choose, including from your own web server. You can upload your application to the service whenever you want, update it as many times as you want, and then publish it when you are ready. Once published, users can see your application, download it, and rate it.
At any time after publishing an application on Android Market, you can upload and publish an update to the same application package. When you publish an update to an application, users who have already installed the application may receive a notification that an update is available for the application. They can then choose to update the application to the latest version.
Before uploading your new application, be sure that you have incremented the android:versionCode and android:versionName attributes in the element of the manifest file. Also, try to remember that the package name must be the same as the existing version and the .apk file must be signed with the same private key. If the package name and signing certificate do not match those of the existing version, Android Market will consider it a new application, publish it as such, and will not offer it to existing users as an update.
