How to change the file's permission in android using chmod

Question

I'm using chmod command to change file's permission but it's doesn't work in my code and my device is rooted too:

String MyFilePath = "/data/data/MyPkgName/database/com.pocketchange.android.http.AsyncHttpRequestService.db";
CommandCapture command = new CommandCapture(0, "chmod  777 " + "\""+ MyFilePath+ "\"");
RootTools.getShell(true).add(command).waitForFinish();

And when it's execute, the command output is :

Unable to chmod /data/data/MyPkgName/databases/com.pocketchange.android.http.AsyncHttpRequestService.db: No such file or directory

but the file is exist, and when I use this code to change the permission of another file in the database directory its success, so what can I do now.

I don't know if the embedded quotes are required. Can you try the command with "ls -l" on the directory and read the output to try to see if one of your assumptions may be wrong. — hack_on, Mar 11 '13 at 09:58

Is there any reason why you're not using java.io.File? https://developer.android.com/reference/java/io/File — Stephen Quan, May 22 '23 at 03:26

Use the chmod command in the ADB shell...

String[] strExec = new String[] 
{ 
       "/system/bin/sh", "-c","/system/bin/chmod 777
};

try {
    Runtime.getRuntime().exec(strExec);
} catch (IOException e) {
    // TODO Auto-generated catch block
    e.printStackTrace();
}

1.Do RootTools.isAccessGiven() check first, then the system will ask for "Root" permission in the style of Dialog. After permitting the root can you successfully run the root command.
2."\""+ MyFilePath+ "\""=> MyFilePath
