打开/查看Android外部SD文件和文件夹

Question

I am running below lines of code to Open Picture Gallery in Android Programmatically,It working fine .

final static int RQS_GET_IMAGE = 1;
Intent intent = new Intent(Intent.ACTION_PICK, android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
startActivityForResult(intent, RQS_GET_IMAGE);

In my application sometimes I need to open the external SD card Root Directory to select random file desired by user. Anyone can guide how can I open (open and explore) the external card files and folders from my application?

Thanks in advance for help .

Answer 1

First you need to set user-permission to write access to SD card in Android Manifest file

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

Without it you can't access to SD card. Next you should work with SD Card like HDD on PC

Hope, it's help you.
