How can I change the Read/Write Permissions of /mnt/SDcard folder on Kindle Fire?

I am trying to develop Amazon In-app in android. For this i download the sample code for from this site https://developer.amazon.com/sdk/in-app-purchasing/sample-code/button-clicker.html. This article suggests that we have to put a file amazon.sdktester.json in mnt/sdkcard folder of device. For this i read article from this site https://developer.amazon.com/sdk/fire/connect-adb.html#InstallApp and do the same. But when I tried to push file on sdcard, the eclipse gives me following error:

[2012-11-19 13:39:39 - ddms] transfer error: Permission denied

[2012-11-19 13:39:39] Failed to push selection: Permission denied

enter image description here

Is there any way to change the permissions of root folder of Kindle Fire?

Solution

  • Please try to use chmod command in the ADB shell...

    Following are some chmod sample:

    1. Add single permission to a file/directory

    Changing permission to a single set. + symbol means adding permission. For example, do the following to give execute permission for the user irrespective of anything else:

    $ chmod u+x filename
    1. Add multiple permission to a file/directory

    Use comma to separate the multiple permission sets as shown below.

    $ chmod u+r,g+x filename

    1. Remove permission from a file/directory

    Following example removes read and write permission for the user.

    $ chmod u-rx filename

    1. Change permission for all roles on a file/directory

    Following example assigns execute privilege to user, group and others (basically anybody can execute this file).

    $ chmod a+x filename

    1. Make permission for a file same as another file (using reference)

    If you want to change a file permission same as another file, use the reference option as shown below. In this example, file2′s permission will be set exactly same as file1′s permission.

    $ chmod --reference=file1 file2

    1. Apply the permission to all the files under a directory recursively

    Use option -R to change the permission recursively as shown below.

    $ chmod -R 755 directory-name/

    1. Change execute permission only on the directories (files are not affected)

    On a particular directory if you have multiple sub-directories and files, the following command will assign execute permission only to all the sub-directories in the current directory (not the files in the current directory).

    $ chmod u+X *
