First u need to add premission in manifest for writeExternal directory and find destintionfolder name .all images stored in this folder — Rohit Heera, Jun 29 '15 at 16:42

Firstly add the permission to the manifest for accessing to the external storage:

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

Then you must get the bitmap of the desired image and create a file in the external storage:

Bitmap imageBitmap = ((BitmapDrawable) image.getDrawable()).getBitmap();
File sdCardDirectory = Environment.getExternalStorageDirectory();
File imageFile = new File(sdCardDirectory, "image.png");

Finally write the bitmap into the file:

FileOutputStream outStream;
    try {
        outStream = new FileOutputStream(image);
        bitmap.compress(Bitmap.CompressFormat.PNG, 100, outStream); 
        outStream.flush();
    } catch (IOException e) {
        e.printStackTrace();
    }finally{
        outStream.close();
    }

You can introduce a boolean for checking if the process of writting is properly completed.

I dont understand u ,, can u explain more… or give me an example — user5050715, Jun 27 '15 at 03:55
