Android :: Improve Eclipse Performance For Projects With Lots Of Resources

Sep 13, 2009

I have notices following:

If I have a project with minimum files in res folder, the project saves quickly, compiles quickly and launches quickly. But if I have a lot of resources, my project is saving, compiling and launching during relatively long period of time. This is really frustrating if you do some minor UI updates, and you have always wait Eclipse to generate R file etc.

Android :: VBOs Really Improve Performance?

Jun 19, 2010

I've been trying VBOs (3D) and I've seen no improvement at all on my Motorola Dext over not using VBOs.I've tried all kinds of configurations, interleaved arrays, by t buffers instead of float buffers, both direct and indirect. My question is, has anybody got any measured improvement in frames per second by using VBOs instead of exactly the same content without VBOs? If and only if so, what were your fps results? And can you therefore show me the "proper" way of doing VBOs instead of not? Has anybody else got exactly the same fps with and without VBOs?

Android :: Way To Improve Performance Of Laptop

Jun 4, 2010

I read on many other topics that the Android emulator starts really slow. Indeed, it takes +15 mins to start. However, on my machine is slow even after that.The 'phone' responds with a 3-4 seconds delay and everything has a huge lag.Is there any way to improve the performance of my laptop (Asus 1201N) is too rusty for the Android emulator? Tried in different emulator resolutions and the result is the same.My laptop has 2 cores with HyperThreading. And it shows as 4 CPU in Device Manager. However, when using the emulator, just one of the graphs is at 100%. Can I do something to make it work multi core?

Android :: How To Improve Audo Playback Performance?

Oct 15, 2009

The game I am working on uses SoundPool for sound effects and MediaPlayer for background music playback. Input happens entirely through the touch screen, with a 20 mS delay after each processed MotionEvent. Sometimes (very rarely) it happens that the background music gets interrupted for a fraction of a second during input. Do you have any ideas how to ensure MediaPlayer continues audio playback during touch screen input? All audio files are in ogg format with various sample and bit rates. Would it be an advantage if all audio files would share the same samplerate and/or bitrate? Do you have any other ideas how to improve audo playback performance?

HTC Droid Eris :: Will Android 2.0/2.1 Improve Performance?

Dec 3, 2009

Will Android 2.0/2.1 improve performance? The Eris is a cool phone and all but it simply cant keep up with me. There is nothing wrong with my phone also. I have rebooted it and have 80mb free memory. Same thing at Verizon store display phone. It just cant keep up and the lag and waiting periods (1 second or so) are annoying me. Yes one second is alot of lag time when you are trying to do things. It sounds like "only one second" but there are 100 of these one second lag times all over the phone. Im not even an "expert" or "hardcore" user.

Anyon know if Android 2.0 will run faster? Playing a simple MP3 while trying to navigate the phone increases the lag times. Why dosnt the older iphone 3g have these lag issues when they both have equal CPUs?

When will Google and HTC aknowledge the MAJOR issue with the ENTIRE phone slowing down the a crawl once available RAM goes under 30mb. (common with all Android phones) Is it SO hard to have the ability to shutdown apps and automatically remove them from ram when Im done using them? This is the same stupidity Windows Mobile went through back in 2003. Yes I understand that Android will remove unused apps from RAM to make room for the next one but this is where the lag is coming from. The entire phone slows to a crawl unless you free up some memory with 3rd party apps.

HTC Droid Eris :: Instantly Improve Performance In 2.1 OTA?

May 25, 2010

I have a couple friends with the Eris that went from loving their phones to hating them shortly after receiving the 2.1 OTA upgrade. They were quite happy with 1.5, but were looking forward to 2.1 - because I bragged about the improvements in the leaks.

I was playing around with their phones last night and they were having serious lag when scrolling, receiving calls and switching from portrait to landscape mode. I turned off window animations completely and those issues went away immediately. The phones are now pretty speedy.

If you're looking for that setting, it's under: Settings > Sound & display > Animation > No animations.

Sprint HTC Hero :: Does A Better MicroSD Card Improve Overall Performance?

Oct 7, 2009

I have seen some threads and articles on a few sites talking about the advantages of a better than stock mSD card for the Hero having a drastic effect on its performance. I have see others stating that a Class 4 or even Class 6 card on the Euro HTC Hero has improved performance by 400%. Now while I know "400%" is a little out there and even sounds exaggerated, I am curious what this group of people has seen or heard. Does a better MicroSD card improve overall performance?

Samsung Behold 2 :: What If Anything Will Upgraded OS Do To Improve Performance Of Processor?

Jan 1, 2010

I've always said that the Behold2 is a great looking phone. It has software/OS issues for sure. However, I don't use the cube so, that bit of nonsense doesn't get in my way. The laggi-ness does get on my nerves because it slows things to a crawl much too often. Sometimes programs or the TouchWiz slider don't open when they should. Frozen-ness happens too.

The scary part is that I have very few third party apps installed. Sometimes the controls for the Media player don't show up at all. So you can see why I am reticent to install anything beyond what I consider to be essentials so as not to over-burden an already beleaguered setup.Considering these known issues, why were we ignored on the Android 1.6 release? We weren't graced with 2.0 either. Now 2.1 is on the horizon and there is no word about its being sent our way. I'd like to think that Samsung or Tmo wants to keep us happy so that we don't jump ship in a few days. I could dump this puppy because I am within my 14 days and am not a happy camper.

Questions: What if anything will an upgraded OS do to improve the performance of our processor? Or, what improvements might we expect with a new OS release?

Android :: Projects In Two Different Locations And Importing In Eclipse?

Mar 10, 2010

I always face this problem in my eclipse. I would like have a copy of the apps in all the versions of SDKs/NDKs. And once I have a project in eclipse, and if I have to import the same project from a new location, I get the message saying "Can't import, project of the same name already exists". Is this how it is? We cant import the same project from its 2nd location in eclipse? Everytime I delete the project from old location and put it in new. I know, it is a very unacceptable approach).

Android :: AIDL In Multiple Projects In Eclipse

Mar 16, 2010

I have problems with the following: I want to create to applications. One with a Android service and one with a Activity that will use functions on the Service. Before I splitted this in to applications I got everything working in one application. I can call functions (that are definned in the aidl - file) on the service without problems.

Now the problems coms. I splitted the application into two parts, a Service application and Gui application. The bindins to the service (in the gui application) works and I see that the service is getting created. Then in the onServiceConnected function of the ServiceConnection class I created the following:

mService = IMyService.Stub.asInterface(service);
And this gives me the following exception:
03-16 13:53:05.549: ERROR/AndroidRuntime(881): java.lang.NoClassDefFoundError: MyPackage.IMyService$Stub

It looks like he can't find the Stub class in IMyService. But the Stub is part of the java file generated out of the aidl-file. Why I get this exception or how I can resolve this?

Android :: Eclipse Not Importing Jar Dependencies Between Two Projects

Jun 7, 2010

Here is the situation.
I have a java project "LicenseGenerator" in eclipse that depends on commons-codec. I have therefore added the commons-codec jar file to the build path. I have Junit tests and everything is working fine. I have made a different project in the same workspace - which happens to be an Android project - that needs to use my LicenseGenerator classes. I added LicenseGenerator to the "projects" tab in the build path - the classes were recognized and I was able to use them.

Everything compiled and ran. However, when the part of the LicenseGenerator that used the commons-codec was called from my Android project I got the following error.
Could not find method
Referenced from method
This basically tells me that the commons-codec was not packaged which the Android project, so I added the commons-codec to the android project as well but the same error appears.

Android :: Including Other Eclipse Projects In Application

Jan 12, 2010

I have a library-only Android eclipse project (no main class, only library classes) that I want to include in my main Android Application project. I went to the Build Path and added the library project to the "Required projects on the build path" on the Projects tab, and checked it on the "Order and Export" tab. However, when the application is run, it emits VerifyError exception, because the class from the library project didn't happen to be packaged together in the apk.

Android :: Referencing Projects Under Java Build Path In Eclipse

Jul 27, 2009

I'm working on two projects. One is essentially a library, and the other is an application using that library. Now from the application project, I want to use the library's classes, so I added that project to the "required projects" under java build path. It seems to compile fine, but at runtime, I get this error:

07-27 11:26:57.037: ERROR/dalvikvm(741): Could not find class 'interdroid.contextframework.ContextManager', referenced from method com.bartvanwissen.contextframeworktest.MainActivity.onCreate

Apparently, the library project's classes are not added to the apk file. How can I make sure they are included? Since I'm working on both projects at the same time, I would like to prevent having to create a jar file every time I want to test something.

Android :: Eclipse Slow When Compiling Resources

Jul 21, 2010

The last couple of weeks, my app is very slow compiling changes when the resources are modified in the project. Doesn't matter if it's strings or layout. Sometimes it takes as long as 30 seconds for the changes to apply. Compiling just the .java files are as fast as ever.

I used to have slowdowns after I having Eclipse open for the whole day, but restarting Eclipse always fixed that. Not this time. All my Eclipse and Android software is up-to-date. Has anyone experience this or have any suggestion as to what could be causing this and a fix? It's really cutting into my productivity.
