I have written a very simple game with some simple animations, but I've noticed that when the phone checks email, or several other apps are running, the animations that update in my thread start behaving slowly or choppy. This is a problem as the game mechanic requires some careful timing of your screen touches based on the animations. So if it starts behaving erratically, the game doesn't really work well - and isn't much fun.
Is there a way to prevent this? Can my threads have a higher priority when they need to run?
Other forums have a thread dedicated to PSX4Droid and how well the app along with the roms work on their respected phone.
This thread is not so much a "How to" but a "What works"
For those just getting started and need to learn how to set up PSX4Droid take a look at a few of the videos on YouTube to help get going.
Now for anyone who has PSX4Droid on the Incredible could you please post what roms/games you have tried and how well they work on the system.
This will help people from putting a certain amount of hours of playtime into a title only to find there is a section they won't be able to advance from.
Games I have tried so far:
Dino Crisis: This one starts off fine but about 30 minutes into playing there is a door you have to go through and the new section won't load basically ending the game.
Dino Crisis 2: Runs fine for the first 5-10 minutes but afraid of the same problems coming up from Dino Crysis 1.
Resident Evil: Only played for 30 minutes but runs fins, also has sound issues.
Resident Evil 2: Played for 1 hour and runs GREAT, has some sound problems.
Resident Evil 3: Same as RE2, played for 1 hour game runs great but has some sound issues.
Diablo: This is a tricky one. Game starts and plays fine in the first town but after talking to everyone there is and entering the church the performance drops off. Now I have restarted this one and took my character directly into the church bypassing talking or doing anything in town and didn't have a problem so this might have a memory issue.
So far from the limited titles I played the RE series works out the best. It should be noted that every game I tried out has some sound issues you just have to live with for now.
How can I implement a run() method of thread if I create a Thread Global?
I mean If I create a Thread Globally then can I implement its run() method {" public void run()"} anywhere in my Application?
In the run() method I have to write the code to perform some action.
IF I can do it then please can anyone show me briefly how to do it particularly.
I am writing an application in which i need to handle messages between the main thread(the deafult UI related thread) and the user created Gamethread.
The requirement is like this.
An activity(say "Activity_X") is setting the view by "setContentView(some "View_Y")". In "Activity_X" i have implemeted "onCreateOptionsMenu()" and "onOptionsItemSelected()" fucntions for creating menus & a switch case for action to be taken on selecting those menus.Menu has items like "resume/pause/zoom/" .
All action to be take on selecting these menus are implemented in "View_Y" in a separate Gamethread by extending "Thread" class.
So whenever a menu is selected in "Activity_X" i need to send a message to "View_Y". And on receiving this ,a particular action/method should be called in View_Y(GameThread).
How can i achieve this using Handlers?Is there any other way of doing this? Please do share with me some code snippets for these.
I have a separate thread running to get data from the internet. After that, I would like to update the ListView in the main thread by calling adapter.notifyDataSetChanged(). But it does not work. Any workaround for that?

I have a bluetooth thread started that handles the bluetooth request. Once the connection is made the thread is killed and a Connected Thread is started. Once the Connected Thread is started I want to turn on GPS so I can start feeding the GPS data through the output of the bluetooth. The problem is, I can't get GPS to start in a seperate thread other than the main Activity. I don't want that to happen as I would like to have this run in the background and not be dependent on the main Activity. I have tried turning on the GPS from inside the Connected Thread but that always leads to a RunTimeException. how to get GPS to run in a thread?
View 2 Replies View RelatedI have google voice and use it for every phone call I make.

View 12 Replies View RelatedI'm trying to determine whether or not my phone is defective, or if this is a current problem with the Cliq.
Of the apps I've downloaded, only a few of them have worked. Of those few that work, some don't work right. Has anyone had problems with these apps crashing on them, or just not working correctly?
- Nice Battery (see description at bottom of: My Ultimate CLIQ settings (so far))
- WeatherBug (kept showing the wrong location, crashed when trying to change location)
- Snake - doesn't work just says its "paused"
- RingDroid - crashes when I select the "Facebook Pop" button
- Layar - screen is rotated 90 degrees at all times
There have been others, but usually I just uninstall them right after discovering it doesn't work right.
I've had an HTC Desire on Orange in the UK for about 6 weeks and it is having persistent problem. Firstly despite having a strong 4-bar out of 4 signal, online services and the internet do not work at all when a 3G signal is being received (e.g. news, weather, all widgets, internet, email etc).Calls and texts do work however with a 3G signal.But when a 3g+ signal (HSDPA) is being received, all internet services as above work fine.However, when a 3+ signal is being received, the phone does not make or receive calls or text messages, and often fails to send texts. Calls I make immediately shut down (bleep + �call ended�), and incoming calls from other people go straight to answerphone. Also often when turning the data connection on/off, it freezes and has to be rebooted, and turning airplane setting on and off does not fix the problem.
I have also tried the different network settings (GSM, WCDMA, auto, etc). �GSM� sends and receives calls and texts but doesn�t work (or is incredibly slow) with internet, and �auto� and �WCDMA only� show the problems as above.I don't think this is a network/coverage issues as, as I have seen many people reporting these same issues on other networks and in other parts of the UK, and I have read that other people are having to manually turn off HSDPA to be able to make calls (using an app?). Even if I can stop HSDPA from connecting to make sure the phone works, I still can�t use the internet at all on 3g � even GSM works better!
Finally, when I connect to a bluetooth device (e.g. car and headphones) the phone will connect briefly, and then randomly disconnect. I have also seen this issue reported elsewhere.I very much like the phone and don't want to get rid of it, but these problems are making the phone unuseable.Also I don't know if I should be contacting HTC or Orange about this. Will the upcoming Android 2.2 fix these problems?Anyone know how to fix this or if I need a new handset? Are there any apps that can help? Also does the Nexus One have these problems and are they fixed by Froyo?
So I made a discovery - my dialpad doesn't work during a call. Even if I bring it up via the softkeys, the numbers don't register a tap...anyone. else have this issue or is it just my phone?
View 49 Replies View RelatedI'm developing a game based on SurfaceView and a game thread for the whole game thing.Now I want to do some HTTP requests triggered on events inside the thread. They should of course be asynchronous, so the game doesn't stop. I found AsyncTask to be a neat way to do this but I'm having trouble implementing this at the moment. Maybe I misunderstood the concept of AsyncTask,I don't know it just drives me nuts as I read docs and blogs and still I don't get it. So sorry if that's a dumb question but I'm mad of thinking about it.
View 4 Replies View RelatedI am new to Java and Android.I would like to retrieve remote data and display it within my activity. To prevent tying up to UI, I understand that I can do this in another thread. (I thought I could just-as-well fetch this remote data from within a service, but that appears to tie up the UI thread also). So now I'm beginning to think I need to either run the logic from a new thread within a service, or run a service within a new thread. But which? I have found many examples online of running new threads or services, but I have yet to find an example of both at the same time.

View 5 Replies View RelatedI have to draw list of 30 articles. I tired using list view but there was some problem as I wanted to user alternate colors like first is white and 2nd is blue where as again 3rd is white and 4th is blue and it goes on..
So I decided to have scrollview and table into it. I set the view using setcontentview which shows loading dialog. then in aysnc task's "doInBackground" method i fetch all articles into the object and then in "onPostExecute" I run a for loop on the object and in each loop i make table row insert article and then insert row into table. and then dismiss loading dialog box.
As i have tabular view in my app and If i remove loading dialog box. While the UI is rendered if someone clicks on other tab. UI is hanged up, After loading all table rows It goes to other tab.
Even after using asynctask why this happens ?
I'm having trouble getting the GPS's onLocationChanged to run on a different thread. I understand how to manage UI thread when I'm calling a function but with the GPS, I don't actively call the function.
My intent is to have a light flash every time the GPS receives a reading. I have put this function in a Runnable. I passed this function to a class that implements LocationListener. Then in the main class, I started a new thread that calls requestLocationUpdates. I was hoping that onLocationChanged of the LocationListener would run in a different thread, post to the callback and make the necessary UI effects in the UI thread. Unfortunately, the program crashes every time it tries to call requestLocationUpdates. What's the proper way of doing it?
Right now it looks something like this
Main class:
CODE:................
LocationListener class:
CODE:...............
The exception says Can't create handler inside thread that has not called Looper.prepare()
I write a thread, and do show() after thread complete, but I always get the error msg bellow, and this show() function is ok, because I put it on other location of program, and it works fine.
View 5 Replies View RelatedHowdy android experts. I thought I knew something about programming.... lots of experience with microcontrollers and embedded simulations that run in a loop and read inputs, do some calcs, send outputs. After days of trying to write a program that prints out a count that increments with a key, I guess I know nothing of how the windows event driven model operates. I see examples that use another thread/task/program to accomplish what I thought would be a couple of lines. After the onCreate, lets say the screen says 'count 0'. The os is now running. right? Any click or key should get 'delivered' to the activity, so it seems I could have an onClick that says count++ and a setText or something and an invalidate, and Bob's Yer Uncle, but no it ain't that easy. I hereby declare that this task is impossible, and no one can show me how to do it.

View 5 Replies View RelatedI've created ProgressDialog with a second thread according to the DevGuide,changes screen orientation or 2) hits the back button twice (first to hide the dialog, second to hide the app) to hide the application and run the app again after a while.Then, onCreate() is called (for the second time), and progress bar stops responding properly. My thread may work for a few minutes and I want to give the user possibility to hide it and do sth else. After a while he might want to run the app again in order to check the progress.I found a few articles concerning this topic, but I couldn't find the exact solution I should chose for this problem. So, could you tell mi what is the proper way to handle this? Should i save the handler and dialog state with "onRetainNonConfigurationInstance()"? If so, how to do it properly and is it safe?
