Get file path from here

Try it -

FileInputStream is = new FileInputStream(new File(filePath));
ByteArrayOutputStream bs = new ByteArrayOutputStream();
int data;

while((data != is.read()) != -1)
   bs.write(data);

is.close();
byte[] raw = bs.toByteArray();
bs.close();

This is one way how you convert a bitmap to byte:

public static byte[] bitmapToByteArray(Bitmap bitmap){
    ByteArrayOutputStream baos = new ByteArrayOutputStream(); 
    bitmap.compress(CompressFormat.PNG, 0, baos); 
    return baos.toByteArray();
}
