Android :: Every Few Hours Eclipse - ADT Runs Out Of Resources
Sep 12, 2010
When I am developing for Android and repeatedly running and/or debugging an Android app in the emulator then about every two hours or so I get an Out-of-memory exception, occasionally also an out-of - resources- or out-of-GWT-handles exception. At that point one can only stop and restart eclipse. Apparently the ADK must be doing something wrong, because I have been developing with Eclipse now for 5+ years and I normally never see this. ADT is a really the exception here. Is there any setting or patch that helps top avoid this? I have already given it more heap space (750M) to stretch the time between these hickups a bit, but that approach isn't really sustainable.
This is using Eclipse 3.5 (Galileo) and the Android SDK r06 running a FroYo AVD.

After deleting a phone device from the emulator, I can no longer hit the green triangle button in eclipse and have it launch my application in the emulator. I had been developing for 2.0.1, but then decided to try my app out in 2.1. I created a phone device for 2.1 and tried running it. I encountered some problems. Eclipse pops up a dialog box: Problem Occurred, Launching "my app" had encountered a problem. An internal error occurred during: 'Launching my app". When I look at details, it says: An internal error occurred during: "Launching Pingo". java.lang.NullPointerException.

The problem I am having is that when I run a FWVGA or WVGA sized emulator it sometimes runs at a MDPI size instead of HDPI. Here is an example with pictures. I create the AVD with the proper hw.lcd.density setting and screen size and it randomly does this. There doesn't seem to be a pattern. I used to be able to just delete the AVD and create it over again and it would fix itself for a while but now it's getting worse.

I am running Eclipse on Win32 and my Android emulator on Linux.
Is there a way to use Win32 eclipse to debug code on the emulator that runs on Linux?

I need to add a res/drawable-nodpi folder to my Eclipse ADT project. My project originally contained drawable, drawable-hdpi, drawable- ldpi, layout, etc subfolders, but no drawable-nodpi. How do I add this to the automatic resource build process? I tried to manually create the subfolder and copy files to it, but those resources are not being auto-generated. How do I make Eclipse utilize the new resources subfolder?

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.

I just had the odd case that my Android project for some reason would not properly rebuild in Eclipse (v3.5/Galileo). Occasionally that happen and so I did the usual Project => Clean... as I always do in such cases. But this time I now have the odd effect that almost all files show bugs, and looking closer it's that the compiler can't find the R-file (which is indeed missing from the gen subtree). How do I force eclipse to rebuild that file?

I have 2 android applications that share 95% of their resources, layouts, strings etc. only a few jpg's are different.
How can I share resources between the different Eclipse Android projects, so as to avoid resource duplication ?

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.

Do those numbers seem normal to the rest of you? Right now if I am using my phone for browsing, video, etc. it will run the battery from full charge to dead in just under 4 hours. If I just leave the phone turned on but with no apps running (standby) it runs out of power in roughly 48 hours. Is this the battery life I should expect from this phone?

In my Android project, I want to loop through the entire collection of Drawable resources. Normally, you can only retrieve a specific resource via its ID using something like:
InputStream is = Resources.getSystem().openRawResource(resourceId)
However, I want to get all Drawable resources where I won't know their ID's beforehand. Is there a collection I can loop through or perhaps a way to get the list of resource ID's given the resources in my project?
Or, is there a way for me in Java to extract all property values from the R.drawable static class?

For example, I want to parse the string below:
Tue Sep 28 18:02:24 GMT+08:00 2010
And I use the pattern for the SimpleDateFormat:
new SimpleDateFormat("EEE MMM dd HH:mm:ss zzzzzzzzz yyyy");
But I keep getting the ParseException.

I have an app that has a few checkboxes in the settings and then compiles a remote sql based on the checkboxes selected. i ran it in the emulator and it's fine. but then i exported it and published it as an app, and the same checked boxes aren't being passed correctly. i wonder if it's a caching issue or something. tried deleting the apks a few times and republish but to no avail. i "fake-edited" the source java and then export again, still no difference.
I'm kind of new to eclipse but is there a force build option? i only see build-automatically option under project but not sure how i can make sure that the apk exported is the same as run in the emulator
edit the emulator is version 1.5, and my phone is nexus one running 2.1- not sure if that makes a difference

Ok so here's the deal guys and gals, I am trying to have my phone assist me with my running. There are plenty of apps that will track my run via gps if I bring my phone on the run with me, but I don't wanna do that. I want to be able to map a course out, enter how long it took me, save the map and even share it with friends. Ideally the app would have the gps running features I mentioned above just on case I ever do start bringing my phone with me. Here is an example of what I mean in website form (unfortunately they make a sweet app for the iphone but their android version is pretty awful right now.MapMyRun.com -

Does anyone know if there is a way to identify (in code, not LogCat) when the GC has run? Perhaps an intent is fired? I could analyze the LogCat output, but it would be ideal if I could determine when the GC has run from my code.

E.g. What happens if the Activity is killed and a query is executing in the ContentProvider? Say that you have a slow network query f.ex.

For my first application, the only testing I've really done to this point is on my Droid X. I want to think through the various hardware differences and come up with a testing plan that is representative of the Android landscape. My initial thought is to create a list of emulators that have unique qualities such as screen size and SDK levels. I've noticed very quickly how the UI of my application will need some adjustment when viewed on devices that don't carry a 4.3" screen. How have you approached this hurdle in your own development?

Does anyone know of, or have implemented, a physics engine which runs smoothly in Android? I have spent the last couple of days trying Phys2D and JBox2D, however both perform very poorly - I am struggling to get even a few objects to simulate smoothly as frequent garbage collection spoils it. One question I do have is will these run smoother on an actual G1 device or is the performance of the emulator accurate?

I want to close my application, so that it no longer runs in the background.How to do that? Is this good practice on Android platform?If I rely on the "back" button, it closes the app, but it stays in background. There is even application called "TaskKiller" just to kill those apps in the background.

I have a WebView. I'm not quite sure how caching works for it. Ideally I'd like to load a web page from the network once (images included), then from then on only ever load it from the local cache. I'm not sure if we have this level of control over webview. Will it at some point just auto-clear the cache? How could I tell? I need to be sure that it's really keeping the page cached between different runs of my application.http://developer.android.com/reference/android/webkit/WebSettings.html.

I would like to add a chat feature to my application, which runs on both iphone and android platform.
Do you have any idea on how to make this ?
I have seen that tutorial : http://mobileorchard.com/tutorial-networking-and-bonjour-on-iphone/, but I don't know if it will work using the android NDK
I have also think about writing the architecture client/server in C but I'm not sure if it's the good solution ..
Do you have any idea ?

I have written a simple Authenticator service to work with the new AccountManager API introduced in 2.0. When I launch a test app that uses the authenticator the authenticator service is launched (as expected) and it's onBind method is called. However, if I run my test application a second time in the same emulator (without restarting the emulator) my service is not launched and onBind is not called.
So far the only way I have found to get my service to launch and onBind to call again is to restart the emulator, which is a very time consuming process. I have looked at the Devices view in Eclipse and ensured that all of my processes have been killed, just in case one of them was just being rebound to or something.

Like as my HTC G2, when i long press the end call key, the phone option dialog shows and my app blurs. But the animation in the app still runs behind the dialog. I hope that the app stops or pauses when i long press the end call key. Can i do this?

I am building a 2D game with Android SurfaceView. When I touch the screen the game animation runs slowly. Why, and how can I avoid this?
The touch events are stubs just like onTouchEvents(MotionEvents ev){ empty };. All of the game logic and graphics draw code are in run() in an extends Thread class.

My game runs fairly well on my phone, but i want to increase the performance by using opengl. However currently i use the Canvas. I am a beginner in opengl. I have to port all my drawing code to opengl. However can somebody give me directions. For example how do i do the following in opengl:
c.save();c.scale(0.3f+scale, 0.3f+scale, width/2, height/2) c.drawBitmap( bMsg.bitmap, width/2 - bMsg.bitmap.getWidth()/2,dy+height/2 - bMsg.bitmap.getHeight()/2, MESSAGE_PAINT);c.restore();
And why cant i just use Canvas as an abstraction layer (facade) for opengl. An implementation of canvas could call the correct opengl methods in order to render. Why do i have to port all my code. I thought the canvas was a good abstraction interface to a drawing surface, why do i have to bother with opengl? It looks like this is possible, when is see the following contructor: "public Canvas (GL gl)" Also the this seems usefull. SURFACE_TYPE_GPU Surface type: creates a surface suited to be used with the GPU So what should i do? Re implementing the GamePainter completely and call opengl functions directly? Or is there some kind of abstraction mechanism, so that i can use OpenGL with just a few lines of code?
