Android androidmanifest. xml Android: Process Element description

Android: process can be used for a single component (activity, broadcast, etc ).

<Application Android: Process = "com. Android. Phone">

ApplicationProgramAll components are running in this process. Each component can overwrite this setting by setting its own process attribute.
By default, Android creates a separate process for each application. All components run in the process. The default process name is usually the same as the package name of the application.
For example, <manifest xmlns: Android = "http://schemas.android.com/apk/res/android"
Package = "com. Lt. mytest">
The default process name of the program is com. Lt. mytest.
Setting this attribute allows the application to share the same process with other applications. Only when the two applications share a userid with the same signature.
<Manifest xmlns: Android = "http://schemas.android.com/apk/res/android"
Android: shareduserid = "android. uid. Phone">
The name of a Linux User ID shared with other applications.
By default, Android assigns a unique user ID to each application. However, if multiple applications set this attribute to the same value, they share the same ID. If these applications are set to run in the same process, they can access each other's data.
