19 Creation of.apk distribution of the project for Real Devices To create an.apk distribution for the marketplace, you need to have an Android developer s account to sign it. Without a developer s Android account, we can create an.apk distribution in debug mode for debug keystore, which is the same as the marketplace mode. Check where your keystone is located, via Windows -> Preference -> Android -> Build, where you will see the Default debug keystore folder (in my case, C:\Documents and Settings\pbao\.android\debug.keystore).

20 Then we are going to create the.apk distribution in debug mode as follows. File->Export->Android->Export Android Application
