Why can't the "data" folder appear the same as in the DDMS file explorer?

Question

I list the files in '/':

File directory = new File("/");
fill_listview(directory.listFiles());

And I get a list:

sqlite_stmt_journals
config
cache
sdcard
d
etc
system
sys
sbin
proc
init.rc
init.goldfish.rc
init
default.prop
data
root
dev

I have two questions:

1. Why can't I access the "/ data" folder as an Eclipse DDMS file explorer?

2. Why is it different from DDMS, which is displayed only:

data
sdcard
system

Thank!

Answer 1

In the root device, you can do this to access the / data folder:

• Open cmd
• Enter ' adb shell'
• su
• Click "Allow" on device
• chmod 777 /data /data/data /data/data/com.application.pacakage
• Go to DDMS view in Eclipse

After that, you can view the files on the device.
