How to delete a file from SD card?
This should be simple for most people, I want to know how to delete a file in the SD card (/sdcard/folder) if it exists i.e?
Try this:
File folder = Environment.getExternalStorageDirectory();
string fileName = folder.getPath() + "/folder/image1.jpg";
File myFile = new File(fileName);
if(myFile.exists())
myFile.delete();
This is accomplished via the java.io.File class. Have a look at the exists() and delete() methods.
