Android : Way To Maintain Multiple Images?
Aug 22, 2010
During my game loop I am constantly loading images using BitmapFactory.decodeResource(getResources(), R.drawable.objectx); Most of the time I'm calling images that have already been decoded earlier. Am I slowing down execution by decoding the resource every time? Is it better to store every image into a Map (or Dictionary) at the beginning of the program? If so, how do you get the resource IDs for all images in the drawable folder?

I would like to know if its possible to prevent my application from looking different every time I run it on a different android phone. For example, on stock 2.2, my seek bar (with default values and theme) has an orange color for the selected portion, whereas on a Samsung Galaxy S (with 2.1), it is green. Also the tab background is grey in stock 2.2, but blue in Galaxy S. On a similar note, my rating bar changes size too. I do not implement multiple screen resolutions and all my drawables are located in the "drawables" folder under "res". I donot specify a minimum sdk requirement.

Is there an app that I can use to maintain the balances of multiple credit cards? The app does not need to be able to directly access the credit card's balances online (straight thru online banking), but I must be able to add transactions and update it manually. I also should be able to manage multiple cards without the app adding the balances of all cards into a grand total (balance).

I need to include multiple images in my Android app. It's like an image viewer/slideshow. Currently I switch between pictures from /drawable-mdpi dir simply with ImageView and adapter, using gestures to left/right. Works but nothing impresive :/
Basically I could use something like Android (2.1) gallery with some image show animation.
1st question: what's the best way to include many (50-100) fullscreen images in App?
2nd: is it possible to use ViewFlipper animations directly to images? or do i have to somehow populate Views?

I was just wondering if Android had built in code so that I could select multiple images in a gallery-view and then have those images exported as filenames in a string array(ex /sdcard/~f1.jpg, /sdcard/~f2.jpg,...).

I'm creating an app that allows the user to zoom in and out and pan around the screen.
My question is this, how would I allow this to be done with multiple images? Lets say I have a background grid image and 3 market bag images. Is there away of doing this neatly and efficiently in Java?
Here's the code I've got so far:
DesignBoard.java
Code:
import android.app.Activity;
import android.graphics.Matrix;
import android.graphics.PointF;
import android.os.Bundle;
[Code]...
For those interested in pinch zoom, visit this link.

I need a small help on rotating one image around its center of axis among multiple images which are drawn to canvas in android.
I am loading images to canvas like below.
canvas.drawBitmap(mMachineBackground, 0, 0, null);
canvas.drawBitmap(mMachineRotator, 0, 0, null);
I want to rotate only the second bitmap around its center of axis instead of rotating the entire canvas(which includes first bitmap also).

Here is the problem, I am building an application and have multiple images that need to switch when the user touches the screen, doesn't matter where the users touches. The press the screen and the images switch randomly. I purchased the ebook "Professional Android Application Development" and have torn though it. I am stumped. I'm thoroughly confused at this point. Any ideas on where I can go or how I can accomplish this?

I want do display some images that I load from a remote source in a gallery. The gallery should let the user do the following things:
-zoom the image (preferably also by pinch-zoom) -pan the image -switch between the different images
Of course most built-in gallery applications can do all of that. So my first idea was to use an ACTION_VIEW intent in order to delegate the task to some gallery application. This however won't work for me since you can only pass the URI of the image you want to display but not the actual bitmap data itself. I can't just pass the URL of the remote image because I need to manage the loading and caching of the data myself. A way around this would be to write the data to a local file and then pass the URI of that file (and deleting the file again afterward). Besides this being less than elegant it won't even do the trick because with an intent like this you can only pass one image at a time.
The built-in Facebook application on the Nexus One actually does exactly what I have in mind for displaying photo albums. It looks like a custom gallery activity they built into their application. Does anyone know whether there are templates available for something like this somewhere that one could reuse? Building something like this from scratch by myself seems too time consuming.

I am basically trying to send more then one image at once through text message is that possible? I know of slideshows but how do i go about creating one and sending it through text message.
I also tried using the search engine on this forum and not a great one in my opinion compare to other search engines i have used in car forums. So if there is already a thread just like the one i have create please redirect me and close my thread Mods.

Does the built in sms app fix the receiving 1 or multiple images as a slideshow? I know it isn't really a bug and is just how the app works, but I was wondering if there were any changes to the sms app in Jelly Bean for those who may not want that feature.
I am currently using Handcent but sometimes I still get images as a slideshow. I'm also having to click on the message to download it before I can view the slideshow.

The requirement is totally simple: I want to have a lite and pro version of an app. There is a little bit of difference between those two apps, but they are 99% identically. Unfortunately it seems that the best choice is to really treat this as two projects that are one and the same and copy over the source code and assets from one to the other. The Android Manifest file must be different, because the Android Market - for some reason - makes the implementation's package name the ID. Working around this ID issue the straight forward approach would be to have a third project with the common code that exports its code, libraries and in a best case scenario also the ressources to the other two objects. Unfortunately this doesn't work. Only the actual Android projects generate the R.class and so the common project would need to be dependent on it..

According to the instructions found here, to make your app state which screen sizes you can support, you'll need to compile your app against Android 1.6.

My ListActivity is bound to an ArrayAdapter where I have overriden the getView() method. If I change the visibility of a widget in that method or modify the view's background color, those changes somehow get lost once that modified list item returns after being scrolled off the screen. In fact, some other view in the list is picking up the changes. How do I get the modified view to look the same when it's redisplayed after scrolling?

I have two spinners in an activity, A and B. Each spinner uses an arrayAdapter linked to one or more string-arrays from an XML file. I need multiple because B's values are populated depending on what is selected in A.

This usually happens when the user hits "Home", does something else, then eventually wanders back into the app - it attempts to go back to where it was before, but the application Context has mysteriously lost all its previously-saved state information (in my case, a few integers and a few Strings). I know this is a very vague question, but are there any cases (other than the user using "back" to back completely out of the application) where the application Context gets completely destroyed even though the application is not terminated? Is there a better way to maintain persistent state information?

How can I maintain the position of my ListView in my activity when I go to another activity (by launching another intent) and then come back (press the back button)?

Well, not sure if this was already somewhere else, but I looked and couldn't find it, so I'm gonna ask here...
What are the required APKs to maintain running the Android OS? I have root access on my Eris, and was tinkering around with a bit with removing some of the preinstalled APKs such as YouTube and stuff like that, just wondering how much I can delete and work to create my own system to a certain extent. Anyone that can let me know what I need would be nice.

I have built an app for the Motorola Droid which should automatically update a server with the phone's location. After the user performs a particular task on the main activity screen, an alarm is set to update the user's location periodically, using a service. The alarm is explicitly stopped when the user completes another task. Thing is, I have set up a location manager within the main activity's onCreate() method which is supposed to place the first acquired lat/long into two textview fields. Even though the manifest is set up for acquiring coarse and fine coords and I'm using requestLocationUpdates (String provider, long minTime, float minDistance, LocationListener listener), with minTime and minDistance set to zero, I'm not seeing the coords coming up on the screen.
With that, I'm not recording any locations on the server. When I seed the textviews with sample coords, they are being recorded fine on the server. I am not at a computer that can run the IDE, so don't currently have the code, but am desperate for some help on this. One other thing is that the main activity screen calls a photography app before the user manually clicks "send data". I'm suspicious that I may need to override the main activity's onResume() method to do this location acquisition.

While developing a sample android application I have constructed two activities
1)Activity 1
2)Activity 2
Now Activity 2 is the foreground activity whereas Activity 1 is the background one. Now user presses Home key. The application(i.e. both the activities) disappear. Now is we relaunch the application we see Activity 1 as the foreground activity. My question is:
1)Does the platform maintain any history entry when pressed home key?
2)How do we take the user to the last launch activity on relaunching the application?

I'm developing one of my first Android apps. I come from an ASP.NET world where it's trivial to have separate Web.config files for dev, test, and production. Does anyone have a good, automated way of doing this for Android via Eclipse?

I'm basically using the same method of loading bitmaps in OpenGL that the SpriteMethodTest example uses and have been unable to get rid of an annoying outline that appears around all of my images.
For example, If I were to load an image of a white circle on a white background, I would expect to see nothing. Instead, I would see my circle because its edge would be gray. In SpriteMethodTest, I replaced the background image with white and was able to see that the edges of the android images flying around also don't seem to be rendered correctly.
Does anyone know how to load images in OpenGL without having a thin outline appear around the images?

I'm working to convert some background images to nine patch so they scale better on different phones.
The problem is that if I have the following resource structure: drawable-hdpi/background.png drawable-hdpi/button.png drawable-mdpi/background.png drawable-mdpi/button.png drawable-ldpi/background.png drawable-ldpi/button.png and then I drop a new drawable-hdpi/background.9.png file into the mix, it breaks button.png during the pre-compile. The error is "No resource found that matches the given name (at 'background' with value '@drawable/button').Simply removing that one nine patch file fixes the build. Should I be able to have some nine patch images and some normal ones, or to have nine patch only in hdpi but not mdpi or ldpi? This is Eclipse 3.5.1 with the latest ADT.

I'm interested in knowing how other people maintain good battery life with their evo. I get about 5 hours a day with moderate usage. I don't do much but put the screen brightness in the middle and occasionally going into "running applications" and closing the ones I don't need or use (most of them being the trashy default stuff); Turn off syncing when not needed; turn off GPS and other seetings that are not continuously needed to be left on.
I also configured my send and receive settings for each mail account. I know there is no official way to close out an app when your done using it, I usually just press the home button when i need to exit an app. Does everyone else do the same? Or is there a better technique to officially close apps and stop them running when you are done using them? Without DLing a task killer app cause I don't want one.? Feel Free to share your ideas or techniques.
