Captured Image Resolution is too big

Question

What I am Doing ?

I am allowing user to capture image, storing it into SD Card and uploading to server.

But getting resolution of Captured image

Try below code , It may help you

first convert your image with your required height and width

public static Bitmap scaleImage(String p_path, int p_reqHeight, int p_reqWidth) throws Throwable
{
    Bitmap m_bitMap = null;
    System.gc();
    File m_file = new File(p_path);
    if (m_file.exists())
    {
        BitmapFactory.Options m_bitMapFactoryOptions = new BitmapFactory.Options();
        m_bitMapFactoryOptions.inJustDecodeBounds = true;
        BitmapFactory.decodeFile(m_file.getPath(), m_bitMapFactoryOptions);
        m_bitMapFactoryOptions.inSampleSize = calculateInSampleSize(m_bitMapFactoryOptions, p_reqHeight, p_reqWidth);
        m_bitMapFactoryOptions.inJustDecodeBounds = false;
        m_bitMap = BitmapFactory.decodeFile(m_file.getPath(), m_bitMapFactoryOptions);
    }
    else
    {
        throw new Throwable(p_path + " not found or not a valid image");
    }
    return m_bitMap;
}


private static int calculateInSampleSize(BitmapFactory.Options p_options, int p_reqWidth, int p_reqHeight)
{
    // Raw height and width of image
    final int m_height = p_options.outHeight;
    final int m_width = p_options.outWidth;
    int m_inSampleSize = 1;
    if (m_height > p_reqHeight || m_width > p_reqWidth)
    {
        final int m_halfHeight = m_height / 2;
        final int m_halfWidth = m_width / 2;
        // Calculate the largest inSampleSize value that is a power of 2 and keeps both
        // height and width larger than the requested height and width.
        while ((m_halfHeight / m_inSampleSize) > p_reqHeight && (m_halfWidth / m_inSampleSize) > p_reqWidth)
        {
            m_inSampleSize *= 2;
        }
    }
    return m_inSampleSize;
}

Answer 2

use FileOutputStream.flush() after writing data...

File file = new File(fileName.toString());
try {
    FileOutputStream stream = new FileOutputStream(file);
    bitmap.compress(CompressFormat.PNG, 100, stream);
    stream.flush();
    stream.close();
} catch (Exception e) {
    // TODO: handle exception
}

You can save Bitmap image following code

Bitmap photo = (Bitmap) "your Bitmap image";
photo = Bitmap.createScaledBitmap(photo, 100, 100, false);
ByteArrayOutputStream bytes = new ByteArrayOutputStream();
photo.compress(Bitmap.CompressFormat.JPEG, 40, bytes);

File f = new File(Environment.getExternalStorageDirectory()
        + File.separator + "Imagename.jpg");
f.createNewFile();
FileOutputStream fo = new FileOutputStream(f);
fo.write(bytes.toByteArray());
fo.close();
