Flushes this output stream and forces any buffered output bytes to be written out.

Usage

From source file:Main.java

public static void takeScreenshot(String fileName, String directory, View view, int quality) {
    Bitmap bitmap = null;/*w w w.j  a va  2s  . c o m*/
    FileOutputStream fos = null;

        if (fileName.endsWith(".png")) {
            bitmap.compress(Bitmap.CompressFormat.PNG, quality, fos);
        } else if (fileName.endsWith(".jpg")) {
