Why is Memory always increase? Can you help me?
Thanks for Avandce!

[EgonOlsen]

All your textures seem to be in non-power-of-2-formats with 1000*something. This increases memory usage at load time because it forces a rescale on each loading. Try to scale them down to 512*512 instead before loading them. The automatic rescale has been removed from latest version anyway. How many textures are you using? Keep in mind that Dalvik's memory is pretty limited.

I try use image import on texture with size 250x250, problem Group heap is always increase not happen.
However Load Texture is always WARNING.

01-30 01:17:43.201: INFO/jPCT-AE(12715): Loading Texture...
01-30 01:17:43.201: INFO/jPCT-AE(12715): [ 1296325063209 ] - WARNING: Unsupported Texture width (250)...resizing to 128...

My aplication is alway draw invalidate streets image(base on Location GPS calculated my scale) in OnDrawFrame every time Location Provider Change.

Thanks Sir for helped me.

[EgonOlsen]

250 is NO power of 2. Using this size will fail on any newer version of jPCT-AE.

[EgonOlsen]

Btw: If want to replace a texture in the manager with another one using the same name, simply use the replace-method. What you are doing causes copies of the textures Being left in gpu memory and objects that use the texture "streets" will be painted all white after that. They don't get the information that their texture had changed this way. I think we recently had another thread dealing with this too.

[buiminhhuy]

Drawable streets;
                  streets= new StreetsDrawable(lsGeo);               
                  Bitmap bitmap = Bitmap.createBitmap(IMG_WIDTH,
                          IMG_HEIGHT, Bitmap.Config.ARGB_8888);
                    Canvas c = new Canvas(bitmap);
                    streets.draw(c);
                    Texture streetsTexture = null;
                    streetsTexture = new Texture(bitmap);
                    streetsTexture.setMipmap(true);
                    if (bitmap != null) {    
                                 bitmap.recycle();        
                                 bitmap = null;    
                                 System.gc();
                              }
                    if(tm.containsTexture("streets")){
                       tm.removeAndUnload("streets",fb);
                       tm.replaceTexture("streets",streetsTexture);
                    }else{
                       tm.addTexture("streets", streetsTexture);
                    }                  
               

I have been use above snip code, and resize image 250x250. However sometime get error below

Grow heap (frag case) to xxxxMB for xxxx-byte allocation

xxxx is number memory  increase than every time draw invalidate streets.
Current, i only use this solution(draw image: paint streets of the real world into image based on address GPS Location).But get problem about memory. I can not resize image smaller, because it had been picture not clearly.(if Solution any can, i hoped that it could keep size of image is 500x500, if 1000x1000 that is good.)

Thanks Sir.

P/S: I do not know to make any way to resolve the problem memory. Please! help me?.

[Kaiidyn]

try resizing your textures to 256 manually.

[buiminhhuy]

i dont see any method of texture in javadoc about resize or setsize of Texture. Can you help me? Thanks.

[Kaiidyn]

resize your textures manually in a program like photoshop or something :-)

[buiminhhuy]

oh, it is image create dynamic. create runtime

[Thomas.]

I never tried this, but maybe it can help

[buiminhhuy]

Thanks, i have been resolve my problem. No WARNING load texture and No Group heap is always increase.

Thanks  EgonOlsen very much.(sory because not read JavaDoc clearly). Thanks sir this days.
Thanks  Thomas very.

I have bean resolve my problem with snip code below:

Drawable streets;
                  streets= new StreetsDrawable(lsGeo);               
                  Bitmap bitmap = Bitmap.createBitmap(IMG_WIDTH,
                          IMG_HEIGHT, Bitmap.Config.ARGB_8888);
                    Canvas c = new Canvas(bitmap);
                    streets.draw(c);
                                       Texture streetsTexture = null;
                    

streetsTexture = new Texture(BitmapHelper.rescale(bitmap, 256, 256));   

streetsTexture.setMipmap(true);
                    freeBitmap(bitmap);
                    if(tm.containsTexture("streets")){
                       tm.removeAndUnload("streets",fb);
                       tm.replaceTexture("streets",streetsTexture);
                    }else{
                       tm.addTexture("streets", streetsTexture);
                    }

I can not understand why sometime Grow heap is increase when draw street, sometime  Grow heap is not increase . although I have been free memory of bimap and manager texture the same than every time draw street.

[buiminhhuy]

i think i will use OpenGlES for draw street of me. Because Texture i can not free memory.

[EgonOlsen]

After all, you can't control the garbage collector. You simply don't know when and why it collects garbage or not. System.gc(); doesn't enforce this by definition. It's just a hint. However, are you still getting OutOfMemory-Exceptions or are you just bothering with that heap-increase-message? I wrote myself a little test case that does this in each frame:

Code Select Expand


cnt++;
if ((cnt & 2) == 0) {
Texture t=new Texture(1024, 1024, new RGBColor(cnt % 255, cnt % 255, cnt % 255));
t.setMipmap(true);
TextureManager.getInstance().unloadTexture(fb, TextureManager.getInstance().getTexture("texture"));
TextureManager.getInstance().replaceTexture("texture", t);
Logger.log("new Texture!");
}


I.e. every second frame, it creates a new 4 MB large texture and replaces the former one with it. This runs without problems, the memory will be reclaimed as needed. However, i get a log message each time i'm doing this:

Code Select Expand


01-30 19:55:04.288: INFO/dalvikvm-heap(491): Grow heap (frag case) to 14.706MB for 4194320-byte allocation


...with exactly the same value of 14.706MB over and over again. So the VM prints out BS here IMHO, but it doesn't hurt. I don't see why it shouldn't work in your case unless the rest of what you are doing (canvas, drawable, bitmap...) is causing a problem somehow. I've read multiple times that working with Bitmap can cause memory leaks for example.
