Android :: Loading Random Image When Activity Is Brought Up - Not Working ?
Jun 20, 2010
I'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.

CODE:..........
Here is the code where the problem lies....
It doesn't give me an error it says exactly this when I run the android emulator
"[2010-08-25 09:12:42 - doppler_test] ActivityManager: Warning: Activity not started, its current task has been brought to the front"
What I think this means is that the intent of the bluetooth function and the button intent is only operation on a hierarchy system. What I mean by this is that if I were to move the button opperator above the Bluetooth stuff the button will work, but currently when the app is run Bluetooth works but when I press the search button nothing happens.
What else may be helpful is my XML code for the button so here it is......

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.

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?

I'm writing an application that starts with a loading activity. In the loading activity the app requests html from web and parses the html, then it sends the parsing result to the main activity. The main activity has several tabs, and contents of these tabs are based on the result of parsing.For example, the result of parsing is a list of strings ["apple", "banana", "orange"], and I need to pass this list to main activity, so that the main activity can create three tabs named after three fruits.I would like to know if there is any way to pass a list of strings among activities, BTW, is it the common way of do this?

I'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'd like to be able to use an image as my background in a relative layout, without it stretching. I don't want to just enter the images details into an XML file, as I want to use different images, with different sizes. I've tried the following, but it just stretches the images (I know the left, top, right and bottom variables have the wrong values, but I've just entered something into them, as a test to see if it makes any difference to the output, but it does not. If it did, I'd calculate the correct values programmaticly : -
RelativeLayout explosionlayout = (RelativeLayout) findViewById (R.id.explosionlayout);
imageAnim = (ImageView) findViewById(R.id.explosion);
Drawable d;
d = this.getResources().getDrawable(R.drawable.bomb);
int left = 10; int top = 10; int right = 20; int bottom = 20;
d.setBounds(left, top, right, bottom);
explosionlayout.setBackgroundDrawable(d);

What i'm trying to do is just simply have the button load an image at random. However, the button doesn't seem to be working. When i first load the activity there it works fine and there is a random image....But when i press the button it's not loading another like i need it to. Any idea what i have wrong here? It looks fine to me...

I am very new to Android (and Java) originally a C# developer.. and am struggling with the concepts and terminology.
I have been through almost all the tutorials and have decided to start on my first test app.The first part of my app is going to involve using the gallery widget (based on the hello gallery tutorial) to display a load of images. (these images will eventually come from the phones camera, but I will cross that bridge later!) My images are currently stored in the drawable folder in my project.As a first step I want to just have the user click on an image and it pops up full screen, just so I know how to get reference to it, but I am struggling. Evetually I want the user to click an image, then a window/activity(?) will open asking them for a bit of text. This will then be store in sqllite against the image. Code...

I've adapted the GridInputProcessor-class of the 3D-Gallery ( http://android.git.kernel.org/?p=platform/packages/apps/Gallery3D.git;a=blob;f=src/com/cooliris/media/GridInputProcessor.java;h=91dfd4783be6b21ec8ff2518a5c244752570e90d;hb=HEAD ) so that it detects upward/downward swipes.
The detection of swipes works, but I now want to start another activity (or draw a bitmap on the currently displayed activity), but I seemingly can't use startActivity(mContext, myIntent), because the class declaration is public final class GridInputProcessor implements GestureDetector.OnGestureListener, GestureDetector.OnDoubleTapListener {so it doesn't extend Activity...
Can I still start an Activity through this class, or how would I go about doing this? I have also tried sending a broadcast, but this is also not "implemented".

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 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?

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.

I just tried a stupid approach and it crashed my app... Basically I have an activity that has three tabs (containing three activities). Each of the tabs gets its input from an xml file downloaded off the net. Everything is fine but when I start my app, it has download the xml file and there's a "wait" time for this.I managed to get around this by adding a splash screen. It looks beautiful but the problem is when I click on the second tab, it still has to get the list off the net, so it looks ugly now... It waits before displaying the list. So what I did was design an AsyncTask that just downloads the xml file. In my main activity, I spawn two tasks initially and send the URL and Intent as parameters. And inside the activities that start inside the tabs, I use a wait(). Inside the AsyncTask, after it is done with the download, I notify the Intent using notify(). This crashed! Of course, I didn't expect it to work but just wanted to try :) Writing it so that I can either get a feedback as to why this failed or to prevent others from wasting their time on this...Now, I am sure many face the problem of a "wait" time inside the tabs. How do I solve this? I am thinking of either dimming the screen and then displaying a series of toasts or display a progress indicator inside the tabs or pre-fetching the xml files... I don't have a clue on how these can be achieved.

How can we use more than one layout file. I have implemented a cutom dialog.That means i have created an layout file for dialog. And one layout file for my activity. But whatever the UI items in dialog layout ile if iam using them by findViewById it is giving me null
I will explain in details here @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); applicationContext=getApplicationContext();
Dialog folder=new Dialog(this); folder.setTitle("Creating folder"); folder.setContentView(R.layout.create_folder); TextView tv=findViewById(R.id.folder_text); //Here folder_text is in my second layoutfile ie in create_folder.xml //In the above statemet i got the null to tv variable. folder.show();

In my android application i am trying to download images from remote server dynamically ( no of images dynamically come ). for downloading all images it is taking 30 to 40 seconds mean time user has to wait to see the activity . But it is the worst case that loading activity after loading all images. I want to load activity first then load images one by one.

I'm not sure what's wrong here, all i want to do is randomly grab an item from my array. Which is just like a random sentence. Then generate another once the button is pressed. All my code looks good to me but it's causing a crash when i hit the button. any ideas?

Im trying to show a ProgressDialog while the activity is loading. my problem is that although i completed all the work in the activity. it takes a long time for the activity to load, i suspect this is because i use
multiple views with multiple listviews with custom array adapters inside a viewflipper. it takes a long time for the UI to show.how would i go about checking that all the UI inside the activity finished loading? or is there a way to preload all the activity and the UI?

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.

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?
