Android的：如何从外部存储中删除的文件？ [英] Android: How to remove files from External storage?

问题描述

我实现它生成一个应用程序，并创造外部存储器中的文件。你们可以帮我怎么才能删除？

感谢您， 钱德拉

修改-1：我添加以下code，仍然我收到了同样的问题，请看看我下面的code，

 字符串FULLPATH =到/ mnt / SD卡/;
                的System.out.println（完整路径）;
                尝试
                {
                    档案文件=新的文件（FULLPATH，audio.mp3）;
                    如果（file.exists（））
                    {

                        布尔结果= file.delete（）;
                        的System.out.println（应用程序能够删除的文件，结果是：+结果）;
                       // file.delete（）;
                    }
                    其他
                    {
                        的System.out.println（应用程序不能够删除的文件）;
                    }
                }
                赶上（例外五）
                {
                    Log.e（应用程序，异常而删除的文件+ e.getMessage（））;
                }
 

在LogCat中我得到的应用程序能够删除的文件，结果是：假。我连着执行此之后，我的屏幕截图。请看看成。并建议我。

解决方案

 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.

解决方案

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
