Question

I would like to create a directory on the SD card of the device running my application when the application is installed, however I am not sure how to accomplish this. Does anyone have any ideas as to how I might create a directory at install time? Thanks in advance for any help.

Sunil,

This can’t be done at install time, but it can be done on the first run…

This can be done by adding the following in your onCreate() method of your first Activity.

if (!Environment.getExternalStorageState().equals(Environment.MEDIA_MOUNTED)){
        Log.d("MyApp", "No SDCARD");
} else {
    File directory = new File(Environment.getExternalStorageDirectory()+File.separator+"MyAppFolder");
    directory.mkdirs();
}

Good luck!
