Usage

From source file:Main.java

    bitmap.compress(Bitmap.CompressFormat.JPEG, 80, outputStream);
    return outputStream.toByteArray();

From source file:Main.java

    ByteArrayOutputStream bos = new ByteArrayOutputStream();
    bitmap.compress(CompressFormat.JPEG, 70 /* ignored for PNG */, bos);
    byte[] bitmapdata = bos.toByteArray();

    // write the bytes in file
    FileOutputStream fos = null;//from  w  w  w  .j  a  v  a 2 s  . c  o m
    try {
