无法以编程方式从外部存储中删除文件

Question

我正在尝试删除路径下的文件

/storage/714D-160A/Xender/image/Screenshot_commando.png

到目前为止，我所做的是：

  try{
        String d_path = "/storage/714D-160A/Xender/image/Screenshot_commando.png";
        File file = new File(d_path);
        file.delete();

     }catch(Exception e){

        e.printStackTrace();
     }

并且文件仍在其位置（未删除:(）

另外，我已在清单文件中授予了权限。

<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.WRITE_INTERNAL_STORAGE" />
<uses-permission android:name="android.permission.STORAGE" />

public static boolean delete(final Context context, final File file) {
    final String where = MediaStore.MediaColumns.DATA + "=?";
    final String[] selectionArgs = new String[] {
            file.getAbsolutePath()
    };
    final ContentResolver contentResolver = context.getContentResolver();
    final Uri filesUri = MediaStore.Files.getContentUri("external");

    contentResolver.delete(filesUri, where, selectionArgs);

    if (file.exists()) {

        contentResolver.delete(filesUri, where, selectionArgs);
    }
    return !file.exists();
}
