Android - Issue stopping a thread
In my application I start a thread that runs a couple audio services by pushing a button, then attempt to stop it by pushing a stop button. The audio portion stops fine, but I see in the debugging window that the thread is still running. Any help would be greatly appreciated
Here is the thread that is started, goTime is initialized to null as a global variable:
goTime = new Thread(new Runnable() {
public void run() {
rec.startRecording();
player.play();
while(isRecording && !Thread.currentThread().isInterrupted()) {
if(goTime.isInterrupted()){
return;
}
ix=0;
while(ix<buf开发者_JAVA技巧Leng){
short[] bufferor = buffers[ix++ % buffers.length];
lastRead = ix;
rec.read(bufferor, 0,
bufferor.length);
buffers[ix]=bufferor;
inter.onMarkerReached(rec);
}
}
if(goTime.isInterrupted()){
return;
}
}});
goTime.start();
And here is the method called when the stop button is pressed:
public void stop(View view){
isRecording=false;
System.out.println("stop called");
rec.stop();
player.stop();
player.flush();
player.release();
goTime.interrupt();
//isRecording=true;
}
sometimes the values of objects between threads are cached by the JVM(or in this case Dalvik) try declaring your isRecording like so:
private volatile boolean isRecording;
The volatile keyword will ensure the values are not cached but always written directly
