Before we have learned how to issue apk, see Pro Android Learning Note (64): Security and Permissions (1): Issue apk, we will learn more about the package.

Each apk has a unique root package name, defined in Androidmanifest.xml, as follows. The developer is signing the package, which is bound to the package name, and other developers cannot update the package.

<manifest xmlns:android= "Http://schemas.android.com/apk/res/android"
package= "Cn.wei.flowingflying.proandroidservice" ... >
