In my application, user can click on a button and then he can select a picture from his gallery. This image is then displayed.
However, when the user performs 3 or 4 times this operation, the following exception is thrown, due to memory allocation problem code...

I need to know how he takes drawable object. I'm collecting some ImageView objects in array, they have background images that are rather big in resolution so they take lot of memory...
I have read somewhere that it will automatically create image with resolution that my imageView have, so i think it will take less memory than first one. Please tell me, if i set scaleType property, will it scale that image? Will that help me to save memory?
There are several custom-made graphic objects (.png files) included in the project inside res/drawable map.
All elements are normally loaded and displayed in the user interface except two icons and so far haven't figured out what causes the problem.
The code which doesn't affect the user interface as it should is...
In both cases there is only ic_volume_small displayed on the screen and the Variables window in the IDE displays the following:
R.drawable.ic_volume_small = Class not
loaded : net.client.android.R$drawable
R.drawable.ic_volume_of_small = Class
not loaded :
net.client.android.R$drawable
The method (member of IconImage class) which should change the icon image is the following code...
Does anyone know what could cause the described problem?
How can i set the opacity of a Drawable object?
View 1 Replies View RelatedI'm designing a custom view which is an X/Y Plot. It's a moving graph that scrolls to the left with time and new Y values are continuously coming in at 10 per second.
I've been able to make it work with an array of integers where the array index is the X value and the integer value is the Y value, but this seems horribly inefficient (Because every time it comes time to re-paint, I have to loop 800+ times to paint the graph). Then we do it all again 10 times a second. yuck.
Can anybody think of a paintable object that I can draw points to and perform some kind of scroll transformation and then just draw the new points each time, rather than the whole canvas?
Any other ideas out there?
I need to create a map with items on it (the map consists of a drawable object, which represents a room) and I thought about using buttons with background images for the items so that they are clickable.
I guess the AbsoluteLayout fits here the best, but unfortunately it's deprecated. What layout would you recommend me for this kind of application ? Is there another layout which supports X/Y coordinates ?
Does all resource (all in res folder if on eclipse IDE), specially drawable image, is loaded to memory during runtime? Or it is just like a file which is available when the application need it?

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?
I am running my application in the emulator using a high density skin (like WVGA800). However the ressources in my application are loaded from the drawable- mdpi folder instead of drawable-hdpi ... what else should I do so that android use the correct folder ?

I'm not an expert on android, but i installed Estrongs task manager and the max memory i get when i kill all apps is about 20mb. i'm often running at about 10-14 at normal use. (i'm sure its much less when the force closes start)

I want to do some automated testcase with Instrumentation . Suggest that my AUT has 2 Activity. After clicking the button in ther first Activity, the second one will be shown with new content base on what we enter in the first Activity.) Instrumentation provides us the function called startActivitySync() and return the Activity object for processing. My question is how we can get the pointer of the second Activity after the it is shown by clicking the button on the first activity.?

I tried to pretty much disable the LMK, and it still did this...
I tried Chrome, Browser Plus, stock ICS browser, Dolphin and Opera (which does this slightly less often) Last time I had this problem was on my old tablet with only 256 MB of RAM. (Which still did this less often than the Note on ICS)
Every time this happened, I had at least 120 MB of ram free. Seriously, the note has a full gigabyte of ram, and yet this happens.
This doesn't happen to me on GB.
Is there anything I can do to make browsing normal again? Like, exclude a browser from getting killed, or something? I'm using a Galaxy Note..

This is the android URI returned by android.provider.MediaStore.Images.Media.INTERNAL_CONTENT_URI content://media/external/images/media/3
When I try to construct a java URI object from this object, I get an IllegalArgumentException with the exception description Expected file scheme in URI: content://media/external/images/media/3 whereas the android URI shows the scheme as content
Never found a solution for the original question. But if you want the byte stream of an image in the pictures gallery, this piece of code will do that.

View 7 Replies View RelatedI was wondering what people do to limit the phones that can purchase my app on Android Market. I image I can limit this to some extent by using the API levels in the manifest but can I limit my app to just Droid/Milestone? I have only tested the app on these phones so I can't be sure that it will work on others. There are known issues with the Milestone and choosing an OpenGL config, among other issues, that I had to work around so it's not unreasonable that other phones can have similar issues. Also how do you do dynamic licenses via http post?
