open failed: EBUSY (Device or resource busy)

Question

I have a strange error in my App.

In my app it is possible to download a zipFile, read the content as what it is and also delete it. Its doesn\'t matter what exactly

Answer 1

This issue may be cause by

• two or more process reference the same file

• file was deleted,but the reference not be killed

However,deleted it,only one reference was killed,or one or more process reference this file also

you can step by step:

before you delete the file you should

• adb shell lsof | grep "com.xxxxxx.android"

The file you have been opened,and which process reference the file which you opened. also,this command ,show us the process id

than,

• adb shell ls -al /proc/%d/fd

Surprise waiting for you, O(∩_∩)O

good luck!
