Use Java thread synchronization:

Have the reader thread "wait" when there is no data and the writer
thread "notify" the reader when more data is available (and when it
should exit its processing loop).

I have code in a worker thread that needs to efficiently read a
constantly-growing input stream from a process.
The issue is that the present design uses a sleep() for a short period
if there is no input presently available, and I'd like the attempt to
read the input stream simply *block* so it magically awakes when more
input is available. I fear this will mean a small hit on phone
responsiveness.
How does one alter code from this form to do such a thing?
BufferedReader bufferedReader =
new BufferedReader(new
InputStreamReader(process.getInputStream()));
do {
String line;
while ((line = bufferedReader.readLine()) != null) {
// new input would be processed here
}
Thread.sleep(500); // TODO: make this go away
} while (true);
