档案文件=新的文件（selectedFilePath）;
布尔删除= file.delete（）;
 

在这里selectedFilePath是文件中要删除的路径 - 例如：

  /sdcard/YourCustomDirectory/ExampleFile.mp3
 

I implementing an application which generates and create files in External storage. Can you guys help me how can we remove that?

Thank you, Chandra

Edit-1: I added following code and still I am getting the same problem, Please have a look at my code below,

String fullPath = "/mnt/sdcard/";
                System.out.println(fullPath);
                try
                {
                    File file = new File(fullPath, "audio.mp3");
                    if(file.exists())
                    {

                        boolean result = file.delete();
                        System.out.println("Application able to delete the file and result is: " + result);
                       // file.delete();
                    }
                    else
                    {
                        System.out.println("Application doesn't able to delete the file");
                    }
                }
                catch (Exception e)
                {
                    Log.e("App", "Exception while deleting file " + e.getMessage());
                }

In the LogCat I am getting Application able to delete the file and result is:false. I attached my screen shot after executing this. Please have a look into that. And suggest me.

File file = new File(selectedFilePath);
boolean deleted = file.delete();

where selectedFilePath is the path of the file you want to delete - for example:

/sdcard/YourCustomDirectory/ExampleFile.mp3
