I did a dumpsys meminfo of my app and each time I go in and out of my activity the asset allocations grows i.e
CODE:............
Is this a concern? What can I do to avoid this? I have a feeling this is the reason for the growing memory usage.

Is it possible for an app to grow or continue to use up internal memory as you use it? I installed a new Android/Facebook app named Dungeon Quest less than a day ago. Since then I have use this app on and off but I have noticed that gradually my phones internal memory has been growing (from 231mb used to 240mb)! I haven't made any of My space is now getting critical.
Is there anyway short of rooting to reclaim this space? This seems to be a buggy app. I'm wondering if its got some kind of error log file growing in my internal memory area?
I've managed to get my allocations down to next to nothing using DDMS (great tool), this has drastically reduced my GCs to about 1 or 2 every 3 minutes. Still, I'm not happy because those usually cause a noticeable delay in the game (on some phones) when you interact with it.
Using DDMS, I know what the allocations are, they are Strings being converted from integers used to display game information to the HUD.
I'm basically doing this:
CODE:.................
This happens once each frame update and the HUD system is modular so I plug things in when I need and this can cause 4 or 5 hud elements to allocate Strings and AbstractStringBuilders in DDMS.
Any way to reduce these further or eliminate all the String allocations and just reuse a String object?
Are you meticulous in removing all per-frame heap allocations from your game? (At least the allocations that you can control and that have practical alternatives.)
While trying to reduce per-frame heap allocations from my running game, I found that method
android.opengl.Matrix rotateM(float[] m, int mOffset, float a, float x, float y, float z)
Does a heap allocation. This means maybe 10 or so extra heap allocations per frame and is the only per-frame allocation left in my application (well, the only one that I can directly control). I am thinking of replacing this with my own version - one that does not do any heap allocations.
I also had some lists that I replaced with my own list implementation because I found that some standard list iterations would create new iteration objects, putting more pressure on the heap and forcing more frequent garbage collection.
I know that I can't eliminate all the heap allocations. In particular, input seems to trigger a bunch of allocations.
I can't help but think that anything reasonable I can do to reduce pressure on the heap will improve the user's experience (if garbage collection is going to stall my game). Obviously there are diminishing returns at some point, so ultimately I have to make a judgement call.
In my android app, is there any way to get the total amount of memory my application is taking up, in the code. I'm using lots of large bitmaps, so it must include external allocations as well. I must, however, be able to get the number in the code, so that I can dynamically adjust to fit the budget I have.
I also need a way to get the total amount I have available (16Mb or 24Mb) as well.
Now that we've had our phones for a few weeks, the Application list is probably growing quite a bit. I know mine is! I wonder, how do you all organize your applications? Do you just put a few frequently used icons on your home screen and left the rest in the drawer? Do you create folders for different categories (Games, Utils, Social, etc) and place apps in there? Do you just load up your 3 home screens (or more if you have a home replacement) with EVERYTHING from the drawer?

Is there something missing from this? Some questions have talked about having this problem when creating a dialog from onCreate, which happen because the activity isn't created yet, but this is coming from a call from a menu object, and the appContext variable seems like it is correctly populated in the debugger.
I'm writing an application which connects to a back office site. The backoffice site contains a whole slew of JavaScript functions, at least 100 times the average site. Unfortunately it does not load them, and causes much of the functionality to not work properly. So I am running a test. I put a page out on my server which loads the FireBugLite javascript text. Its a lot of javascript and perfect to test and see if the Android WebView will load it. The WebView loads nothing, but the browser loads the Firebug Icon. What on earth would make the difference, why can it run in the browser and not in my WebView? Any suggestions.
More background information, in order to get the stinking backoffice application available on a Droid (or any other platform except windows) I needed to trick the bakcoffice application to believe what's accessing the website is Internet Explorer. I do this by modifying the WebView User Agent.Also for this application I've slimmed my landing page, so I could give you the source to offer me aid. package ksc.myKMB;

1- Does Android Browser (Éclair code base) support the "plug-in" or not?
2- Why "Google Gears" support is removed from the clair code base?

At first,I have a database created by using Ruby on rails.I just already implement insert function(HTTPPost) in my Android Application and it's work.But I don't know how to retrieve specific record from my databases and insert it back to specific record in Android (Like edit function in RoR)This is my insert code :
private void insertComment() {DefaultHttpClient client = new DefaultHttpClient();HttpPost post = new HttpPost("http://10.10.3.87:3000/comments");
// Configure the form parameters
List<NameValuePair> nvps = new ArrayList<NameValuePair>();
nvps.add(new BasicNameValuePair("comment[content]", t_comment.getText().toString();
nvps.add(new BasicNameValuePair("comment[id_account]", "1"));
nvps.add(new BasicNameValuePair("comment[id_place]", Integer.toString(position)I really try many ways out but it doesn't work and it takes very long time to fight with this piece of code. Actually, I really don't know how to specify RowID to HTTPPost.

But I don't know what I should put in the mime type. I want to be able to process the live camera previews if the user selects the menu option. So what do I put into the type tag of the intent-filter? Also I suppose I won't be using ALTERNATIVE or SELECTED-ALTERNATIVE for the category as I want to deal with the whole intent?

View 4 Replies View RelatedI have a question about bluetooth RSSI functionality on the Android (either 2.0 or 2.1):
It's easy enough to get the RSSI value when a bluetooth connection is created, but how can you repeatedly get the RSSI value of a connection that is already active? It's really important to be able to do this, because this lets you determine if bluetooth devices are close to each other or far away, but I can't find any appropriate function calls in the Android API.
I am having a bit of a problem with my Android. So what happened was I downloaded "DroidRootPro" from the market. I rooted my phone with this, installed the 800MHZ ROM image, rebooted and the phone came up great. I was actually surprised on how fast it became. Once the phone came back up, I tried installing one of the custom themes that came with that app (I know I should have left it alone). The phone than rebooted and I was never able to bring it back up. It gets stuck in this endless loop where it tries to boot but doesn�t get past the "Droid" splash screen, it just keeps rebooting every time.
Things I have tried:
-Wipe data/factory reset (in recovery mode), no go.
-Wipe cach partition, no go
-Restore from a "nandroid" backup, no go. I tried pretty much every combination of restores and am unable to bring the phone up.
Is there anyway I can download the factory image that comes with the phone, put it on an SD card and restore to that? I have looked all over but cant find any information on this.
I am trying to develop an app to supplement the built-in music player. I've used git to download the com.android.music package and looked around at its code. I can launch the music player by copying some of its code and launching activities with intents.
Now what I need to do is get a handle to its current view. In the MusicUtils.java file, I see a line that says
View nowPlayingView = a.findViewById(R.id.nowplaying);
I'd like to do the same thing. Only I don't have access to the R.java file, so I can't write e.g. R.id.nowplaying. How do I do this? How do I reference the music players R.java? I do know the R.java stuff is declared public so that shouldn't be a problem. Right?
Is it even possible? I saw this related question and am now wondering: http://stackoverflow.com/questions/2437271/how-to-load-com-android-music-code-into-eclipse-and-compile
