Create multi-user dual-open and multi-Open Applications in android 5.0 (2), android5.0

Create multi-user dual-open and multi-Open Applications in android 5.0 (2), android5.0

The previous section describes how to create a user

Create multi-user dual-open and multi-Open Applications in android 5.0 (1)

Why do we need to create a User? For example, if the window system creates a user, it will operate under the current User. The android multi-user system is like the window system.

After creating a user, you can perform operations under the current user to install or start an application.

With a user, create a workspace under the user, and install and start the apk In the workspace.

Specific operations:
