Hi, All packages have a directory to store preferences, databases and files etc. To support multiple users in JB 4.2 a per-user directory structure is created that corresponds to the old /data/data structure where internal data is stored. So if user "0" have an apk installed with package name "com.example.test" you will also have a directory:
/data/user/0/com.example.test/ Pre JB 4.2 this would be: /data/data/com.example.test/ Now for the Android core UI (not to be confused with SystemUI) the package name is "android" and defined in : frameworks/base/core/res/AndroidManifest.xml <manifest xmlns:android="http://schemas.android.com/apk/res/android"; package="android" coreApp="true" android:sharedUserId="android.uid.system" android:sharedUserLabel="@string/android_system_label"> So basically the directory in question is the internal data storage for this package and can be used as defined by the API: http://developer.android.com/guide/topics/data/data-storage.html#filesInternal In general the directory structure for this is: /data/user/<user_number>/<package_name>/ Best regards, Mikkel Christensen On Wednesday, May 29, 2013 2:44:36 PM UTC+2, AndroidCompile wrote: > > Hi, > In JB 4.2 there's a directory named "/data/user/<user_num>/android/" for > each user. > My guess is that it is created and used by the system UI, but if so, to > what purpose? > Ho is it different from previous Androd versions that didn't need this > directory? > How is this directory created and which application uses it? > > Thanks, > > -- -- unsubscribe: android-porting+unsubscr...@googlegroups.com website: http://groups.google.com/group/android-porting --- You received this message because you are subscribed to the Google Groups "android-porting" group.
