I want to display a fancy 'loading' image at my app's startup time.
The problem: my startup code is mostly GUI related, hence needs to run on UI thread.
Is there a way to do both - that is run UI-related code on UI thread while an image is displayed to the user?

Currently I'm successfully loading and displaying an image from a webserver using the code below.
URL imgURL = new URL("http://www.xxx.com/myimage.png"); URLConnection conn = aURL.openConnection(); conn.connect(); InputStream is = conn.getInputStream(); BufferedInputStream bis = new BufferedInputStream(is); bm= BitmapFactory.decodeStream(bis); bis.close(); is.close();
canvas.drawBitmap(bm, 0, 0, null);
What I want to do is load it from a resource. I've put myimage.png into res/drawable and referenced the bitmap as follows :-
Bitmap bm = BitmapFactory.decodeResource(getResources(), R.drawable.myimage);
However when I try to display it with canvas.drawBitmap(bm, 0, 0, null); I get a Force Close. What am I missing?
I use http://stackoverflow.com/questions/541966/android-how-do-i-do-a-lazy-load-of-images-in-listview/3068012#3068012 to load images in a ListView and a GridView. It works but the images are loaded form bpttom to top. How to fix that?
Bonus Question: Can I use a loading animation in a image view while the real image is loaded? Right now it's just a default image.
My application needs to load and process some data at the startup which delays the displaying of the GUI quite a bit. I addressed that problem by starting a new thread to load and process the data. It solves the problem nicely, but is there a better way to do asynchronous processing in Android applications that I missed?

View 3 Replies View RelatedI read about in the google documents that the 3 folders corresponds to different screen types and that android would select the image from different folders automatically according to the screen type. I read that WVGA will load from drawable-hdpi and HVGA will load from drawable-mdpi. When I tested with 2 emulators both running 2.1, each with HVGA and WVGA. It turns out that they are both reading the image in mdpi. If I deleted the image in mdpi then they read from hdpi. Can someone answer why emulator with WVGA is reading from drawable- mdpi?
View 4 Replies View RelatedI've been staring at this for hours. It compiles fine with no errors and loads the activity on my nexus. The button and the menu items load fine with no issues at all. It's simply not loading any of the drawables i'm specifying :/ any ideas what I did wrong?
All I want is whenever this activity is brought up it randomly chooses an image from the drawables i specify.

Some of you may met the same problem, I was using BitmapFactory.decodeStream, and got this exception: Code...
I know the reason is because the BitmapFactory is trying to decode an uncompressed version of a big image(in my situation, jpg). I can use BitmapFactory.Options.inSampleSize to fix it. but my question is what's the maximum size that VM would like to allocate for loading a image with BitmapFactory? so I can do some scale before it loads.
So I have a rooted Eris (checked positively using terminal emulator) running a 2.1v3 ROM. What I'd like to do is eventually get to the 2.1 OTA ROM. Earlier I downloaded ROM Manager which, after some searching gave me some problems other people have been having. I can't flash to the ClockworkMod recovery image as it gives me a "Error occurred while attempting to run privileged commands!" message. I tried reinstalling, fixing permissions etc. all with the same results. So now i'm trying to flash Amon's recovery image instead using Terminal Emulator and the command line: flash_image recovery /sdcard/file_name_here.img only to yield the message that the file could not be found or something. I'm on a mac and I saw another way on here that involves running commands from your computer to your phone using the skd. I started to do that only to run into a "permission denied" when attempting the first "adb" command line. Am I missing something? I'm trying to read and re-read as closely as I can. I'm not entirely comfortable with this whole process but I'm trying to take the time to really understand it and i'm still having difficulties.

View 6 Replies View RelatedI've looked through the documentation and I can't seem to figure out how to have the screen blured/greyed when I select an activity that may take a while to load.
This seems to be an Android standard (both the Camera app and the Camcorder app do it when first selected), but I don't see any documentation on it. I even tried looking through the source of these apps on git, but couldn't seem to find it.
I've written an app, thats loading images either using the android gallery app or by taking a photo using the cam. When I now load an image using the gallery, everything is fine. When the code is being executed a second time (for loading another image), the application crashes.
try { Uri data = intent.getData();
ContentResolver cr = this.getContentResolver();
Bitmap mBitmap = null;
mBitmap = Media.getBitmap(cr, data);
imageView.setImageBitmap(mBitmap);
} catch(Exception e){ showToast(this, "Failed loading image from gallery");
return;
}
The code crashes at the line:
mBimap = Media.getBitmap(cr, data);
Everything is initialized, there are no null values etc. The strange thing is: no exception is thrown, I don't get into the catch block to determine whats going wrong. Am I not allowed to "re-use" the content resolver? Do I have to free it after the first usage or something like this?

Modify and rebuild the Android operating system, and flash it onto a phone.
I'm not able to find anywhere a downloadable 2.0 or 2.0.1 for the ADP2, nor any indication that it could be done. To the contrary I see all kind of discussions suggesting it's either not possible, or at least not YET possible.

I can't get the emulator to load when running programs from Eclipse 3.4.2.
View 3 Replies View RelatedI'm still learning how to use the dev tools. Using MotoDev which is Eclipse, I wrote a basic "hello world" app. When I run the program, the emulator starts up. It took a few restarts of the emulator and Eclipse until my Hello World icon appear in the emulator. I noticed at one point that a status message said it was sending over the .apl file, which is when my app finally appeared in the emulator. I made changes to my code (Hello to Goodbye) and now..I can't figure out how to "send" to changed app to the emulator. The original app is not being replaced with the changes. What do I need to be doing to reload the changed application on to the Android emulator?
View 1 Replies View RelatedI've done the "Hello World" tutorial which it worked fine the first time I tried it. Now every time I run it I get the emulator's main screen showing up instead of the "Hello World" text. With main screen I mean a background image with the current time and a battery charging icon.
I'm using Log.i in the activity and it seems it's loading fine, because I can see the logs in the LogCat's view.
Is there any known issue about it?
Requirement: 1. The program must be on top of SDK only, no hacking! 2. When a TEXT SMS is arriving to Android mobile, the program must intercept the TEXT SMS to analyze the SMS content (access the whole SMS data) 3. In terms of the SMS content, the program determines if the SMS is erased as it doesn't exist. No notification, no update to Inbox UI. 4. Power cycle the Android phone, the SMS is not seen at Notification or message Inbox
Can any one help with the solution? Or which API shall we look into?

View 5 Replies View RelatedI have some xml files with a custom format (based on the scxml specifications) that I want my program to read. I've already written the code to read it, but I'm running into problems actually reading the file itself. I want the file to be compiled with the apk, as it will not be changed at all during run time. So I put the file (test.xml) in the res/xml/ folder, and got the inputstream by using:
getResources().openRawResource(R.xml.test);
But when I read in this inputstream it is complete jibberish, which makes me suspect it is being read in binary, as openRawResource() is often used for binary files like images, if I am correct. What is the correct way to do this?

View 2 Replies View RelatedSo I'm attempting to make a widget at someone's request. I'm new to Android development, so this widget isn't terribly complex. However, I'm having some difficulties with the layout.
My main.xml file looks like this:
CODE:..............
So it's a layout of two rows, the first row consisting of three buttons and the second row consisting of three TextViews. When I try to test the widget, however, I get a widget with the words "Problem loading widget" on my AVD. Is there an issue with my XML, or is it something else?
