How to convert a bitmap to a jpeg file in Android? [closed]

Answer 1

I think this is what you need

bitmap.compress(CompressFormat.JPEG, 90, outputStream);

I hope this will help you.

Answer 2

Use this:

Bitmap bmp = null;
ByteArrayOutputStream stream = new ByteArrayOutputStream();
bmp.compress(Bitmap.CompressFormat.JPEG, 100, stream);
byte[] byteArray = stream.toByteArray();

for that you can use this:

FileInputStream fileInputStream = null;

File file = new File("yourfile");

byteArray = new byte[(int) file.length()];

try {
    //convert file into array of bytes
    fileInputStream = new FileInputStream(file);
    fileInputStream.read(bFile);
    fileInputStream.close();

    //convert array of bytes into file
    FileOutputStream fileOuputStream =
            new FileOutputStream("C:\\testing2.txt");
    fileOuputStream.write(bFile);
    fileOuputStream.close();

    System.out.println("Done");
} catch (Exception e) {
    e.printStackTrace();
}
