Android Note: Androidmanifest.xml properties in detail (i) of the Shareduserid

First, Shareduserid

Android:shareduserid= "Com.rongqin"

Features of the UserID:

1. Identity as an APK identity

2. UserID corresponds to a Linux user, so accessing data between different apk (users) is forbidden by default.

How does the data exchange between the different apk through UserID?

In the Android system, the APK can read data between each other condition is: the same signature, and the Androidmanifest.xml file is configured in the same Android:shareduserid attribute value, then two apk run in the same process, can access any data from each other.

Ways to access other APK resources through UserID:

1. the same Shareduserid is configured in the Androidmanifest.xml of the application and plug-in (such as skin) programs:

<?xml version= "1.0" encoding= "Utf-8"? ><manifest xmlns:android= "http://schemas.android.com/apk/res/ Android "package=" Com.lonshine.skin "android:versioncode=" 1 "android:versionname=" 1.0 "android:shareduserid=" C Om.rongqin ">

2. access the resources in the APK:

Context context = Createpackagecontext ("Com.lonshine.skin", context.context_ignore_security);

Gets the context that corresponds to the Com.lonshine.skin, and can access any resource in the Com.lonshine.skin by returning the context object.

For example, apply the APK to get the bg.png in the plugin apk:

drawable drawable = Context.getresources (). getdrawable (r.drawable.bg);

This gives a reference to the image, and other XML resource files are obtained in a similar manner.
