Answer 1

Sdcard is mounted or not .....

if(Environment.getExternalStorageState().equals(Environment.MEDIA_MOUNTED)) {

    // SD Card is mounted

} else {

    // SD Card is not mounted

}

Answer 2

I've find a Way from Here .

It provides Simple way to Check that -

String state = Environment.getExternalStorageState();
if(Environment.MEDIA_MOUNTED.equals(state) || Environment.MEDIA_MOUNTED_READ_ONLY.equals(state))
{
   //Whatever we want
}else
{
   //Whatever we want
}

Thanks for all of you Replying My Question.

Answer 3

您可以在保存之前检查外部存储状态 。

Answer 4

There are a couple of different ways to do this, but the best one is probably to use getExternalFilesDir . This will return null if the sdcard is not available. An added bonus is that it will be removed, when the user removes your application.

If you do not wish to use this feature, you can simply see if your directory exists, or if you can create it. Eg. if(!dir.exists() && !dir.mkdirs()) then external storage is not available.
