- ddms] transfer error: open failed：Permission denied

Question

I get a trouble when learning android Data-Persistence. I changed the daenter image description hereta/data/com.flexible.filepersistencetest/files/data permission to 777. But I still can't pull it to my PC.

when I try to delete Nexus_5_API_24.avd 's permission of Read-Only, the Read-Only will be back. It really exaust me. Any advice is ok, thank you very much!

Answer 1

1. change file permissions.

   

   C:\Android\sdk\platform-tools> adb shell 
   generic_x86:/ $ su
   generic_x86_64:/ # chmod -R 777 /data 
   generic_x86_64:/ # exit
   

2. run the below commands under the terminal in Android studio integration.

   C:\Android\sdk\platform-tools> adb shell 
   generic_x86:/ $ 
   generic_x86:/ $ exit 
   $ adb root 
   restarting adbd as root
   $ adb shell 
   generic_x86:/ # exit
   

3. open cmd windows.

   C:\Android\sdk\platform-tools> adb pull /data/data/xxxx C:\Android\sdk\platform-tools 
   

   or use "pull" button
