I have written a file manager.

=============== Problem description ====================

Connect your mobile phone to your computer and use your own file manager. After you delete or create a folder, it will be displayed on your mobile phone. However, the new folder or deleted folder will not disappear on your computer (that is, it will not be refreshed, the result is the same after the connection is disconnected. But you can use the file manager that comes with your mobile phone to see the effect. Why !!!

============= Solution 1 ======================

What do you use on the computer?

============= Solution 2 ======================

What do you use on your phone?

============= Solution 3 ======================

I directly open the portable device, but what I use to open it is not the main reason, because when I use the file manager that comes with my mobile phone to create a file, the computer will display, another problem is why the files under sdcard cannot be viewed under File Explorer in eclipse.

Let's see, you will obviously know the problem. adb does not display the sdcard content. It will use the linux command instead. You will see it with the adb shell.

============= Solution 4 ======================

Because the method you opened is incorrect.

============= Solution 5 ======================

Cmd-> adb shell-> cd sdcard
