• Ideal way to cancel an executing AsnycTask

  - by Samuh

  I am running remote audio-file-fetching and audio file playback operations in a background thread using AsnycTask. A Cancellable progress bar is shown for the time the fetch operation runs. I want to cancel/abort the AsnycTask run when the user cancels(decides against) the operation. What is the ideal way to handle such a case? Thanks.

• Notify a service from a PhoneStateListener

  - by LucaB

  Hi I have built an application that listen to call state changes, and I want to notify a service when the call_state became IDLE. All the components I have are functional, I just need to notify (not start) a service for this. What's the correct practice, maybe using AIDL? Because, in a PhoneStateListener, I can't bind to a service. Do I have to start an activity for that?

• Trying to attach a file from SD Card to email

  - by Chrispix

  I am trying to launch an Intent to send an email. All of that works, but when I try to actually send the email a couple 'weird' things happen. here is code Intent sendIntent = new Intent(Intent.ACTION_SEND); sendIntent.setType("image/jpeg"); sendIntent.putExtra(Intent.EXTRA_SUBJECT, "Photo"); sendIntent.putExtra(Intent.EXTRA_STREAM, Uri.parse("file://sdcard/dcim/Camera/filename.jpg")); sendIntent.putExtra(Intent.EXTRA_TEXT, "Enjoy the photo"); startActivity(Intent.createChooser(sendIntent, "Email:")); So if I launch using the Gmail menu context It shows the attachment, lets me type who the email is to, and edit the body & subject. No big deal. I hit send, and it sends. The only thing is the attachment does NOT get sent. So. I figured, why not try it w/ the Email menu context (for my backup email account on my phone). It shows the attachment, but no text at all in the body or subject. When I send it, the attachment sends correctly. That would lead me to believe something is quite wrong. Do I need a new permission in the Manifest launch an intent to send email w/ attachment? What am I doing wrong?

• Problem with EditText.requestFocus()

  - by synic

  In the onCreate() of an activity, I've got a call to requestFocus() on an EditText. Immediately after, I've got the following: System.out.println(mEdit.isFocusableInTouchMode()); System.out.println(mEdit.isFocusable()); System.out.println(mEdit.isFocused()); These were just put in while I was trying to figure out what is wrong with this activity... they all print "true". However, as you may have guessed, the EditText does NOT have focus, and if I try to start typing, nothing happens. I have to click on the EditText to being typing. I can't see that anything else has focus, but obviously something has to have it.. how can I find out what it is?

• rotate an image aroound a point

  - by Girish

  Hi all, I have an image which is of rectangular dimension, eg 30 x 60 pixels I want to rotate this image around the bottom center of the image, i.e i want to set the pivot in the above example as (15, 60 )pixel. I am using a drawble and matrix to get this done, whatever i try i always end up rotating around center of the image. Code is : Bitmap bitmapOrg = BitmapFactory.decodeFile("/sdcard/DCIM/2010-06-01_15-32-42_821.jpg"); // float angle = (angle + 10.0f)%360.0f; if(null !=bitmapOrg) { int width = bitmapOrg.getWidth(); int height = bitmapOrg.getHeight(); int newWidth = 15; int newHeight = 15; // calculate the scale - in this case = 0.4f float scaleWidth = ((float) newWidth) / width; float scaleHeight = ((float) newHeight) / height; /* Canvas c = new Canvas(bitmapOrg); float px = ; float py; c.rotate(angle, px, py)*/ // createa matrix for the manipulation Matrix matrix = new Matrix(); // resize the bit map matrix.postScale(scaleWidth, scaleHeight); // rotate the Bitmap // matrix.postRotate(45); // recreate the new Bitmap Bitmap resizedBitmap = Bitmap.createBitmap(bitmapOrg, 0, 0, width, height, matrix, true); // make a Drawable from Bitmap to allow to set the BitMap // to the ImageView, ImageButton or what ever BitmapDrawable bmd = new BitmapDrawable(resizedBitmap); ImageView imageView = new ImageView(this); // set the Drawable on the ImageView imageView.setImageDrawable(bmd); // center the Image imageView.setScaleType(ScaleType.CENTER); // imageView.layout(100, 300, 0, 0); // linLayout.addView(imageView); // add ImageView to the Layout linLayout.addView(imageView, new AbsoluteLayout.LayoutParams( LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT, 10, 30 ) ); can anyone let me know how to get this rectified?

• How to send a JSONObject to a REST service?

  - by Sebi

  Retrieving data from the REST Server works well, but if I want to post an object it doesn't work: public static void postJSONObject(int store_type, FavoriteItem favorite, String token, String objectName) { String url = ""; switch(store_type) { case STORE_PROJECT: url = URL_STORE_PROJECT_PART1 + token + URL_STORE_PROJECT_PART2; //data = favorite.getAsJSONObject(); break; } HttpClient httpClient = new DefaultHttpClient(); HttpPost postMethod = new HttpPost(url); try { HttpEntity entity = new StringEntity("{\"ID\":0,\"Name\":\"Mein Projekt10\"}"); postMethod.setEntity(entity); HttpResponse response = httpClient.execute(postMethod); Log.i("JSONStore", "Post request, to URL: " + url); System.out.println("Status code: " + response.getStatusLine().getStatusCode()); } catch (ClientProtocolException e) { I always get a 400 Error Code.

• Why are my CATransitions acting up?

  - by Regan

  I am using the following code to switch between views with CATransition. CATransition *applicationLoadViewIn = [CATransition animation]; [applicationLoadViewIn setDuration:20]; [applicationLoadViewIn setType:kCATransitionPush]; [applicationLoadViewIn setSubtype:kCATransitionFromTop]; [applicationLoadViewIn setTimingFunction:[CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionEaseIn]]; ViewToSwitchTo *myviewcontroller = [[ViewToSwitchTo alloc] init]; [self.view.layer addAnimation:applicationLoadViewIn forKey:kCATransitionPush]; [self.view addSubview:myviewcontroller.view]; It functions mostly how I want it to. It pushes from the top like it should, however it for some reason acts strangely. First, the view I am switching to starts coming in from the bottom like it should, but for some reason, the view that I am switching FROM appears over the top of it with low opacity, so you see both of them. However, you also see the view that is coming in, shifted maybe 100 pixels upwards, on top of itself and the other view, once again with low opacity. Just before the halfway point of the the transition, everything works fine, you only see the view that is coming in and the view going out, doing what they should be doing. But slightly after the halfway point, the view I am switching to appears in its final destination, under the view I am switching from, and the view I am switching from has been reduced in opacity. What is going on here?

• How to keep the session of user login?

  - by YaW

  Hi, I have an app that requires user to register. I've got the app conected to PHP in my server to do the logic of register/login and so, this is not problem at all. But, I want to keep a session of the user in local, so the user doesn't have to login again every time he runs the app. So, I want something like this: First time user, he opens the app, register and login. Do some stuff with the app and closes it. Open the app again, the user is recognized so he doesn't need to login again. I only need to store an ID and a Username (both fetched from the DB in the login php method). What's the best way to do this?? I've thought about doing a custom preference, store the data in files or even a local DB (sqlite). Any suggestions?

• Live Folder: browser intent error

  - by MrSnowflake

  I'm trying to make a Live Folder with URIs. The intent I set to the Live Folder items is an Intent{Intent.ACTION_VIEW, Uri.parse(url)}. I have verified url is indeed http://www.google.com (for testing purposes). But when I click the item in the live folder I get an error message: "Application is not installed on your phone." I guess I'm missing something, but I have no idea how to make the browser launch.

• Which View Engine are you using with ASP.NET MVC?, and Why?

  - by Sosh

  Hi, I'm thinking of experimenting with alternative View Engines for ASP.NET MVC, and would like to know what other people are using. Please let me know 1) Which View Engine you use, and 2) Why. The standard 'web-forms' view engine is of course a valid answer, but please say so only if you have decided to use it for a reason, not just 'Becuase I can't be bothered to change it' ;) Thank you!

• Caching generated QR Code

  - by Michal K

  I use zxing to encode a qr code and store it as a bitmap and then show it in ImageView. Since the image generation time is significant I'm planning to move it to a separate thread (AsyncTaskLoader will be fine I think). The problem is - it's an image and I know that to avoid memory leaks one should never store a strong reference to it in an Activity. So how would you do it? How to cache an image to survive config changes (phone rotation) and generally avoid generating it onCreate()? Just point me in the right direction, please.

• In an ExpandableListView, how can I show one additional line at the end of the child results?

  - by fiXedd

  I have created a custom ExpandableListAdapter and everything works properly. What I'd like to be able to do is in each of the groups add a different type of child to the end. I have tried adding 1 to the getChildrenCount() number and then testing isLastChild in the getChildView() method, but that doesn't seem to work. If a group has three children what I have working looks like this: Group NormalChild NormalChild NormalChild But I'd really like something like this: Group NormalChild NormalChild NormalChild AlternateChild The idea being that the AlternateChild could be a link to more info about the group. Any Ideas? EDIT: ListView has addFooterView() which will allow you to add a footer to a whole ListView... wonder how to add them to the ExpandableListView's children, or if it's even possible

  I have a custom notification with a button. To set the notification and use the event OnClick on my button I've used this code: //Notification and intent of the notification Notification notification = new Notification(R.drawable.stat_notify_missed_call, "Custom Notification", System.currentTimeMillis()); Intent mainIntent = new Intent(getBaseContext(), NotificationActivity.class); PendingIntent pendingMainIntent = PendingIntent.getActivity(getBaseContext(), 0, mainIntent , 0); notification.contentIntent = pendingMainIntent; //Remoteview and intent for my button RemoteViews notificationView = new RemoteViews(getBaseContext().getPackageName(), R.layout.remote_view_layout); Intent activityIntent = new Intent(Intent.ACTION_CALL, Uri.parse("tel:190")); PendingIntent pendingLaunchIntent = PendingIntent.getActivity(getBaseContext(), 0, activityIntent, PendingIntent.FLAG_UPDATE_CURRENT); notificationView.setOnClickPendingIntent(R.id.button1, pendingLaunchIntent); notification.contentView = notificationView; notificationManager.notify(CUSTOM_NOTIFICATION_ID, notification); With this code I've a custom notification with my custom layout...but I can't click the button! every time I try to click the button I click the entire notification and so the script launch the "mainIntent" instead of "activityIntent". I have read in internet that this code doesn't work on all terminals. I have tried it on the emulator and on an HTC Magic but I have always the same problem: I can't click the button! My code is right? someone can help me? Thanks, Simone

• Checkbox 'Checked' in ListView is restored after scrolling

  - by adrianrdzv

  I'm having the following problem: I have a ListActivity, which its ListView is composed by an icon, text and a checkbox (using LayoutInflater). The Adapter for the ListView extends ResourceCursorAdapter (i.e. the data source of the ListView is retrieved from a database, also the Checked status of each row) Everything works pretty Ok, except when I uncheck/check the checkbox in any row, if I scroll down until the modified checkbox is no longer visible, and then scroll up, the checkbox is restored to its original state. The database IS modified, this is not the problem (i.e. if I modify a row and exit the activity, and enter again, the modified row is displayed Ok). My guess is that this has something to do on how the list is rendered because for some reason the ListView "renders" the original state of all rows when it was first populated when scrolling. I've been looking around for this bug but I don't find anybody that had this problem. I appreciate any advice you have.

• Does CodeIgniter have to load view in the final step?

  - by Peter

  I have a function function do_something() { // process $this->load->view('some_view', $data); exec('mv /path/to/folder1/*.mp3 /path/to/folder2/'); } My intention is to move files after outputting the view. But apparently it is done before rendering the view. My question is, does $this->load->view(); have to be the final step in a function? I did a little research, and seems like my question is similar to this topic. Correct?
