static final String TAG = "myLogs";
Button button;
private ProgressDialog progressDialog;

/** Called when the activity is first created. */
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    // Get the view from main.xml
    setContentView(R.layout.photo);
    // Show progress dialog

    // Locate the button in main.xml
    button = (Button) findViewById(R.id.button);

    // Capture button clicks
    button.setOnClickListener(new View.OnClickListener() {
        public void onClick(View arg0) {

            progressDialog = ProgressDialog.show(PrasePhotoProba.this, "",
                    "Downloading Image...", true);

            // Locate the class table named "ImageUpload" in Parse.com
            ParseQuery<ParseObject> query = new ParseQuery<ParseObject>(
                    "newImage");

            // Locate the objectId from the class
            query.getInBackground("1",
                    new GetCallback<ParseObject>() {

                        public void done(ParseObject object,

Save Bitmap using this code:

File file = new File(Environment.getExternalStorageDirectory() + filepath, GiveAnyimageName + ".png"); FileOutputStream fOut = new FileOutputStream(file);

bitmap.compress(Bitmap.CompressFormat.PNG, 100, fOut);
fOut.flush();
fOut.close();
