I currently have two activities. One for pulling the image from the SD card and one for Bluetooth connection.
I have utilized a Bundle to transfer the Uri of the image from activity 1.
Now what i wish to do is get that Uri in the Bluetooth activity to and convert it into a transmittable state via Byte Arrays i have seen some examples but i can't seem to get them to work for my code!!
Bundle goTobluetooth = getIntent().getExtras(); test = goTobluetooth.getString("ImageUri");
is what i have to pull it across. What would be the next step?
From Uri
to get byte[]
I do the following things,
InputStream iStream = getContentResolver().openInputStream(uri); byte[] inputData = getBytes(iStream);
and the getBytes(InputStream)
method is:
public byte[] getBytes(InputStream inputStream) throws IOException { ByteArrayOutputStream byteBuffer = new ByteArrayOutputStream(); int bufferSize = 1024; byte[] buffer = new byte[bufferSize]; int len = 0; while ((len = inputStream.read(buffer)) != -1) { byteBuffer.write(buffer, 0, len); } return byteBuffer.toByteArray(); }
