I am writing a application which will write to a file. Now I want to show the contents of the file but How do I delay the show function so that there is enough time for the writing to be done before continuing?

It seems that this question has been asked before, I just would like to know whether there is an update in Android.I plan to write an audio application involving low delay audio I/O (appr. < 10 ms). It seems not to be possible based on the methods proposed by the SDK, hence is there - in the meantime - a way to achieve this goal using the NDK?

View 3 Replies View RelatedI am new to android development, also new to java. I have many years of experience with OO PHP, so it's not hard for me to quickly learn Java and Android, but I still don't know many things like Thread class. I just started developing a simple app. What I want to do is that when a button is clicked, then the TextView is update in this way: the background is changed to black (by default it's set to white) Then it should wait a half a second and then set the background back to white and update the text inside the TextView
Here is my code, it's inside my Activity class:
public synchronized void onClick(View v) { // TODO Auto-generated method stub switch (v.getId()) { case R.id.btnPlay: showNewDraw(); break; } protected void showNewDraw() { textResult.setBackgroundColor(Color.BLACK); textResult.setText("Before sleep"); try { Thread.sleep(500); } catch (Exception e) { textResult.setText("Something wrong"); } textResult.setBackgroundColor(Color.WHITE); textResult.setText("After sleep"); }
The way it works now is that it seems to actually take 1/2 second from the time the button is pressed and text is updated, but the background is not reset to black and back to white - it always stays white. Either it is being set to black and instantly reset to white or it's just never set to black. What should I do in order for the "delay" effect to work?
I need to let service sleep for 0.5 sec just as using Thread.sleep(); is there any method??

I'm in a process of creating a memory game. My problem is that whenever i click for the second time, i can't even see toggled button. To be clear - first click toggles the togglebutton, so i can see the number it holds, the second click on a different togglebutton is suposed to toggle it, show me the number and then proceed to either set a score +1 if numbers are the same, or reverse them back again if they're different.
Below is the code that i use as my onClick function, i've been thinking about putting some kind of sleep or delay function somwhere in the second "if block" - (if(klikniecia ==2)).

I am using a menu in my application Same as this post... I am using a gallery view for display my menu items
Text Gallery on Android?
Problem is that, i implement onItemSelected listener for gallery, so that when new item is selected data related to that topic loaded. But i also want to allow user to scroll the gallery fully. but each time when user move to next item onItemSelected() function called and it start loading data.
All i want to do is to put some delay in onItemSelected() function, so that if in between that delay user scroll next item than there is no need to load data of previous but for the current. Time may be 1 second. If user dose not go for next item in 1 second, that data of that item must be loaded.
I thought to start a thread,but each time for onItemSelected() there will be new thread...
I try this to.

But Fond Exception.

Is it possible to set a delay at which the scroll bar at the right side appears? The idea is that when the user begins to scroll, the scroll bar does not show up immediately, but if the user scrolls long enough.
I was looking for some time now and found just a getter method getScrollDefaultDelay (), which gets the time in ms when the scroll bar dissapears. How could I control the delay in my case?

How to decrease the delay?
I want to be able to call the following method after a specified delay. In objective c there was something like:

Our team has been working on a live video application for Android and we'd like to get to a very low end-to-end delay. We use H.264 coded video, RTP packetization, and RTSP to reach the player. We have been experimenting with CIF resolution on Android 2.0. We have been experiencing about 3 seconds of delay on the player side. Any tips on how we could reduce it?
View 2 Replies View RelatedI am working on a game that displays its graphics through a modified SurfaceView.The game scrolls around a map based on the location of the main character.That all works fine.I am trying to add a feature to the game that allows you to touch the screen and drag the camera around to see other parts of the map.This is where I am running into trouble.The game's SurfaceView overrides 'public boolean onTouchEvent (MotionEvent event)'to call another method in the game's thread which handles the events.Sometimes, this works fine (although the frame rate drops significantly while the screen is touched).Other times, there will be a delay of several seconds before the game responds to a touch event, during which time the game continues, but the user loses all control.During these delays, a message sometimes appears stating that my activity is not responding, and giving the options to 'Force close' or 'Wait'.If the user selects 'Wait', the game almost always resumes right away, but these delays are obviously not acceptable.The delays occur only the first time the screen is touched after the game is started.Once the game has resumed after a delay, the touch events work just fine again.

View 1 Replies View RelatedI wrote an app that saves a camera picture to the SD card, then accesses the file later to display it into an ImageView. This works fine for all devices except the HTC Droid Eris (maybe the version Eris is running?):
ImageView img = (ImageView) findViewById(R.id.ImgProfile1);
BitmapFactory.Options options = new BitmapFactory.Options(); options.inSampleSize = 4; Bitmap bm = BitmapFactory.decodeFile("sdcard/" + filename, options); img.setImageBitmap(bm); Is there a different method of referring to the sdcard location on 1.5, 1.6, or the Eris itself?
I have a Receiver for BOOT_COMPLETED intent and it will start a Service by calling startService with an intent and the Service processes that intent in onStartCommand function by spawning a thread that does a HTTP post to a server.On powerup, sometimes it takes 3 to 5 seconds to get the active data connection on phone, when this happens Service fails to do HTTP post as there is no data connection. Is it possible for the Receiver to send the intent to Service using startService with a delay.? so that when onStartCommand of Service is called data connection is ready to post data.

View 4 Replies View RelatedAn app I'm developing opens a TCP socket connection to a server. That works great, no problems. What I want to do is simulate network delay and slow speeds, but the changes don't do anything. I telnet in to the emulator console just fine and can set the delay and speed changes, but they don't affect my app in any way. Even disabling data entirely (gsm data off) doesn't do anything. However, all of the settings affect the browser, just not my app. I'm just using a regular Java socket (java.net.Socket). What am I missing?

View 2 Replies View RelatedI noticed this before 2.2 Froyo update, but it seems to be worse now. Whenever I head to the market to install an app, I will click the "install button" and then click "okay" and it states that my app will be downloaded. However, the progress bar will remain at "initiating download" or something of sort and can take anywhere from 30 seconds to 5 minutes to download and install. Is anyone else receiving this lag with the market, or does anyone know a fix?

View 1 Replies View RelatedSo I'm listening to my music on the Droid and notice that the songs have a varying delay between them. Sometimes its not very noticeable and other times it's almost a full second delay before the next song plays. I was wondering, what causes this? Is it the phone itself or does it have to do with the song files? On my computer there is never a delay, each song plays continuously one immediately after the other.
