[android-beginners] Re: Real-time audio processing
Why have you chosen 10ms? (just out of curiousity). If you record at 44khz, you are grabbing 44 samps per ms, or 440 samps in 10ms. I dont think you can record from the mic higher than 16khz on an ADP2/Google Ion at least. The audio routines have a 'minimum buffer size' that you should probably use. Here's an experiment you can try to determine minimum acceptable latency... have a buddy walk 30 or 40 feet away from you. Have him talk to you from this distance. Watch his lips. The delay is 1ms per foot. Is there a noticable loss of sync between lips and ears? If not, this proves that 30 or 40ms is acceptable. I have noticed that the 300ms delay across a stadium at a concert is nuts. You see the drummer hit a rimshot, but you dont hear the Whack! for 300ms.

[android-beginners] Programming model for embedded programmers?
I finally realized why I cant find a good overview of android programming tecnique that doesnt assume that the student is a proficient windows/event driven programmer. Android is a stack on top of java, which is a stack on top of an operating system, and I betcha most experienced java programmers have never really wondered what goes on below the java interpreter. It isnt necessary. Just call the function, and assume that there are lots of spare mips and megabytes left on the pc. Us old embedded programmers are painfully aware of the number of cycles to read a file and/or draw rectangles because weve probably written every subroutine in a file system and a graphics package at one time or another. My model is that after oncreate returns to the operating system, every event that gets delivered to the activity is sent by the operating system, and the activity gets a quantum to run, however long that is (100ms?) and one really has no idea how many ms will elapse until the activity gets to run again. Horrible for real time stuff like embedded guys are used to. The huge complex overhead of splitting a simple program that does input, process, output and runs in a loop into two tasks makes no sense because both of these tasks are being run by the operating system. Just more overhead. There doesnt seem to be a way to generate a 50ms timer event and run a program at a hi priority. Do any android gurus have an embedded backfround also? I know my lack of 'windows' model programming hinders my understanding, and I'd be grateful for a link to some examples that might help. I have no prob generating a timer interrupt that hits every 100usec on a 20mhz 8 bit microcontroller. Hard to believe I cant run a program faster than every 100ms on a 500mhz 32 bit arm. -- You received this message because you are subscribed to the Google Groups Android Beginners group. NEW!

[android-beginners] Re: Programming model for embedded programmers?
Is knowing how multithreaded operating systems work a prerequisite for being a java and an android programmer? Then how does a university teach java? Do those guys know how multithreaded operating systems work? I don't think I've ever even seen the term multithreaded operating system before. I've read about multithreaded languages, and multi tasking operating systems, but maybe this is part of the secret java cult? Kind of like ham radio. You cant join their club till you learn their lingo. Would this satisfy you as a real question?: Do any android programmers that also are embedded programmers ever recall reading any articles that might explain some of the similarities and differences?

[android-beginners] How often does an activity run?
If we run a simple little hello world program that just puts some text in a textview, I see the the onCreate runs, and I guess it calls ondraw once, then it sort of returns to the os, and if we have registered a sensor changed or an onclick listener, we can read the sensor and call invalidate and the os will call ondraw again, and it all is usually 'fast enough'. But my question is: Does ondraw ever get called again?

[android-beginners] dev phone 2, 1.6 and bluetooth?
I have a dev phone 2 (htc ion?) with os 1.6. My boss has a moto droid with 2.0 and I can compile the bluetooth chat demo app and load it into his phone and it doesnt stop; It does bring up the unexpected stop dialog on my 1.6 phone.

[android-beginners] example that increments a variable on the A key?
My app 'almost' works. Its like a clock (its an auto gauge) with a resource bitmap as the dial and the needle is another resource that reads into a canvas, and I can draw it rotated like they do with the lunar lander example. What I'd like to see is an example that uses the onKeyDown keyevent.KEYCODE_A to increment a variable, and prints that variable out using drawText. I'm confused about what is the top level class. The activity? Then I need another view to draw the dial using onDraw? Then I need an override to grab the key events, but by now the member mCount that I declared to hold the count that gets printed out is out of scope? I'm an Old C Programmer, and I cant quite grok what needs to be public and protected and final and static. So basically, if someone could show me this small example that increments a variable on the A kay and prints it out, I think it would be very helpful.

[android-beginners] Re: All combinations of os and res ok?
Thanx Walt. I WAS wondering about the Google APIs I assume if one writes an app using maps, locations, etc, one needs the Google APIs. I'm just trying to get Real Simple single function apps working that test drawing on a canvas, loading and scaling a bitmap, popping up a toast when I click a button. You know, the basics.

You'll need to post more details (like the actual error) or else no one will be able to help. Here's a shot in the dark (since some folks at work hit this today): when you create the AVD you can target (for example) Android 1.6 - API Level 4 or Google APIs (Google Inc.) - API Level 4. Often you need the latter version to get the API support or else apps won't run (and possibly won't even install, not sure).
