Question

I am using a bluetooth barcode reader to deliver text to an edit text. The problem is that it cuts the barcode text for about half the time and delivers me an incomplete text.

I am using the class “BluetoothSocket”.
This is my reading code:

int bytes = socket.getInputStream().read(buffer);

message = message + new String(buffer, 0, bytes);

// Send the obtained bytes to the UI Activity
handler.post(new MessagePoster(textView, message));

I am looking for a way to make the action of getInputStream() be longer

Answer 1

Something like this should work, just keep going until the string is the expected length. I’m assume the stream just keeps going.

InputStream stream = socket.getInputStream();
StringBuilder builder = new StringBuilder();
do {
    byte [] buffer = new byte[256];
    int bytes = stream.read(buffer);
    builder.append(new String(buffer, 0, bytes));
} while ((builder.length() < 10));
String completeStr = builder.toString();
