Access the SD card files from Android application

I have the following requirements:

1. When the user clicks on the button , the SD card should be accessible to the user.

2. The user clicks on a specific image & I need to save the SD card path of the image selected

3. I need to resize the image before displaying that to the user within the Android application

Kindly provide me any blog/article link from where I can 开发者_如何学JAVAget the sample code for the same. Thanks in advance.

You can use standard file APIs to access "/sdcard", or more safely:

Environment.getExternalStorageDirectory() 

Also, you can scale images easily using

Bitmap.createScaledBitmap()
