Add :

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

In your manifest file, otherwise the source cannot be downloaded.

If you want to save it in sd card you need another permission:

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

In order to save it.

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

If you want to get that file in the future.

Next if you want to save it to an external directory, you can try this:

    public void setUpDirectory(String folderName,String source){

        File directory = new File(Environment.getExternalStorageDirectory().getAbsolutePath()+File.separator+folderName);

        if(!directory.exists() && !directory.isDirectory()) {
            directory.mkdirs();
        }

        URL imageurl = new URL(source); 
        Bitmap bitmap = BitmapFactory.decodeStream(imageurl.openConnection().getInputStream());
        saveFile(directory,bitmap);
    }


private void saveFile(File fileName,Bitmap bmp){


FileOutputStream outputStream = null;
try {
    outputStream = new FileOutputStream(fileName);
    bmp.compress(Bitmap.CompressFormat.PNG, 100, outputStream ); // 100 will be  ignored
} catch (Exception e) {
    e.printStackTrace();
} 
finally {
    try {
        if outputStream != null) {
            outputStream .close();
        }
    } catch (IOException e) {
        e.printStackTrace();
    }
}


}

Use GLIDE library it automatically store your image into Cache .....

   Glide.with(context).load(url).into(profileImage);

Note:- Only first time you require internet for loading image. When Image load its working on without internet.

EDIT:- use this gradle

compile 'com.github.bumptech.glide:glide:3.7.0'

Output:-

To save it into sd card you must declare uses permissions write read from sd card in manifest, also ask user for these permissions for android 5.0+. All this is documented clearly in android developers official website. Change MainActivity.class to getApplicationContext()
