[Android] A code, two versions

Maintain the same code, compile two versions, and need to modify the package name. Specific as follows:

(1) Right-click on the project name--Android Tools--Rename application package, one-click to modify the pack name

(2) When installing these two versions on the same phone, the Install_failed_conflicting_provider error is prompted, and the solution is to modify the Android PROVIDER in Androidmanifest.xml: Authorities values, for example:

Use in version V1

<android:name= "Dataprovider"    android:authorities= " Com.testv1.app.provider "></provider>

In version V2, use the

<android:name= "Dataprovider"    android:authorities= " Com.testv2.app.provider "></provider>

So that the Install_failed_conflicting_provider error can be resolved.
