  • Android: Quitting the Looper?

    - by stormin986
    I have a thread I use to periodically update the data in my Activity. I create the thread and start a looper for using a handler with postDelay(). In onDestroy() for my activity, I call removeCallbacks() on my handler. Should I then call handler.getLooper().quit()? Or not worry about it and let the OS deal with it? Or would it just run forever then, consuming CPU cycles?

  • How to change size of Android ScrollView

    - by user611923
    I have a layout like this (abstracted): Scrollview - fill_parent LinearLayout - wrap_content ImageView 1 - wrap_content ImageView 2 - ... ImageView 3 ... In the course of user interaction some images are replaced by larger or smaller ones, shortening or lenghtening the area to be scrolled. And that is the problem. The Scrollview (SV) does not know about the change, so either it scrolls over a lot of empty space at the bottom, or cuts off a picture or two at the bottom. Question 1: Can I somehow make the SV readapt to the changed hight of the LiearLayout (LL)? Question 2: I can obtain the current size through getHight on the LL. But supplyong it to the SV via changed LayoutParams does not work - of course, that would only change the height of the SV on the screen. Is there a way to put the changed height of the LL into the SV in the code, somehow? Question 3: I havn't tried it yet. Would creating the SV, LL and its children in code and then adding/removing children of changed size as required, make the SV adapt to the changes? And last question: Is there a better aüpproach, except using ListViews?

  • Weird Overlay draw behaviour when zooming in the MapView [android]

    - by Itsik
    I've extended Overlay and implemented draw() in order to draw some stuff onto the map. When zooming is done through mapController.zoomIn() (called when doubleTapping the map), the overlay is drawn properly onto the map. BUT whenever I zoom in/out with the built in zoom controller, the overlay is not drawn properly and panning the map is needed to get the overlay refreshed.

  • Android Template Application?

    - by stormin986
    I have built an application that I want to use as the foundation for a few other variants. The variants will come from assets / resource files and a unique AndroidManifest.xml. However, I want to be able to leave all the application code alone (modifying the package of all my classes, etc). I'm having a hard time figuring out how to do so. My first thought was to simply have my main application in its own package, and then specify the specific application package in the manifest. However, this gives me issues with the generated R.java class, since it is generated to be in the main application's package. Anyone have any thoughts on how to accomplish this? To have a code baseline, and the application variants happen in resources/assets and the manifest?

  • Web image loaded by thread in android

    - by Bostjan
    I have an extended BaseAdapter in a ListActivity: private static class RequestAdapter extends BaseAdapter { and some handlers and runnables defined in it // Need handler for callbacks to the UI thread final Handler mHandler = new Handler(); // Create runnable for posting final Runnable mUpdateResults = new Runnable() { public void run() { loadAvatar(); } }; protected static void loadAvatar() { // TODO Auto-generated method stub //ava.setImageBitmap(getImageBitmap("URL"+pic)); buddyIcon.setImageBitmap(avatar); } In the getView function of the Adapter, I'm getting the view like this: if (convertView == null) { convertView = mInflater.inflate(R.layout.messageitem, null); // Creates a ViewHolder and store references to the two children views // we want to bind data to. holder = new ViewHolder(); holder.username = (TextView) convertView.findViewById(R.id.username); holder.date = (TextView) convertView.findViewById(R.id.dateValue); holder.time = (TextView) convertView.findViewById(R.id.timeValue); holder.notType = (TextView) convertView.findViewById(R.id.notType); holder.newMsg = (ImageView) convertView.findViewById(R.id.newMsg); holder.realUsername = (TextView) convertView.findViewById(R.id.realUsername); holder.replied = (ImageView) convertView.findViewById(R.id.replied); holder.msgID = (TextView) convertView.findViewById(R.id.msgID_fr); holder.avatar = (ImageView) convertView.findViewById(R.id.buddyIcon); holder.msgPreview = (TextView) convertView.findViewById(R.id.msgPreview); convertView.setTag(holder); } else { // Get the ViewHolder back to get fast access to the TextView // and the ImageView. holder = (ViewHolder) convertView.getTag(); } and the image is getting loaded this way: Thread sepThread = new Thread() { public void run() { String ava; ava = request[8].replace(".", "_micro."); Log.e("ava thread",ava+", username: "+request[0]); avatar = getImageBitmap(URL+ava); buddyIcon = holder.avatar; mHandler.post(mUpdateResults); //holder.avatar.setImageBitmap(getImageBitmap(URL+ava)); } }; sepThread.start(); Now, the problem I'm having is that if there are more items that need to display the same picture, not all of those pictures get displayed. When you scroll up and down the list maybe you end up filling all of them. When I tried the commented out line (holder.avatar.setImageBitmap...) the app sometimes force closes with "only the thread that created the view can request...". But only sometimes. Any idea how I can fix this? Either option.

  • Can I use a Google Appliance/Mini to crawl and index sites I don't own?

    - by SkippyFire
    Maybe this is a stupid question, but... I am working with this company and they said they needed to get "permission" to crawl other people's sites. They have a Google Search Appliance And some Google Minis and want to point them at other sites to aggregate content. The end result will be something like a targeted search engine. (All the indexed sites relate to a specific topic) The only thing they will be doing is: Indexing Content from the other sites/domains Providing search functionality on their own site that searches the indexed content (like Google, displaying summaries and not the full content) The search results will provide links back to the original content Their intent is not malicious in nature, and is to provide a single site/resource for people to reference on their given topic. Is there anything illegal or fishy about this process?

  • ClickableSpan on TextView in App Widget

    - by Dave Allison
    I have created an App Widget for Android 1.5. It uses a TextView to present a number of individual Text Links using ClickableSpans. However, the onClick event handler on the ClickableSpan is never called, it appears that you can not select individual components on the widget just the whole widget. This approach works fine for a normal app, so what I do I need to change to make this work for a widget?

  • SHA-256 encryption wrong result in Android

    - by user642966
    I am trying to encrypt 12345 using 1111 as salt using SHA-256 encoding and the answer I get is: 010def5ed854d162aa19309479f3ca44dc7563232ff072d1c87bd85943d0e930 which is not same as the value returned by this site: http://hash.online-convert.com/sha256-generator Here's the code snippet: public String getHashValue(String entity, String salt){ byte[] hashValue = null; try { MessageDigest digest = MessageDigest.getInstance("SHA-256"); digest.update(entity.getBytes("UTF-8")); digest.update(salt.getBytes("UTF-8")); hashValue = digest.digest(); } catch (NoSuchAlgorithmException e) { Log.i(TAG, "Exception "+e.getMessage()); } catch (UnsupportedEncodingException e) { // TODO Auto-generated catch block e.printStackTrace(); } return BasicUtil.byteArrayToHexString(hashValue); } I have verified my printing method with a sample from SO and result is fine. Can someone tell me what's wrong here? And just to clarify - when I encrypt same value & salt in iOS code, the returned value is same as the value given by the converting site.

  • Android: Width and Height of View After Orientation Change

    - by David
    I need to get the width and height of a WebView and pass them in the query string of the URL I am loading in the WebView. I have found a way to do this in onResume(). Since the width and height are not calculated at this point, I post a Runnable to the WebView to be queued for after the UI loads. Here's my problem: when the orientation changes, I am handling it in onConfigurationChanged. When I try to post a Runnable in onConfigurationChanged to the WebView, the WebView's width and height end up being the old orientation's width and height. At what point can I intercept the new width and height after orientation change?

  • Android, NetworkInfo.getTypeName(), NullpointerException

    - by moppel
    I have an activity which shows some List entries. When I click on a list item my app checks which connection type is available ("WIF" or "MOBILE"), through NetworkInfo.getTypeName(). As soon as I call this method I get a NullpointerException. Why? I tested this on the emulator, cause my phone is currently not available (it's broken...). I assume this is the problem? This is the only explanation that I have, if that's not the case I have no idea why this would be null. Here's some code snippet: public class VideoList extends ListActivity{ ... public void onCreate(Bundle bundle){ final ConnectivityManager cm = (ConnectivityManager) getSystemService(Context.CONNECTIVITY_SERVICE); ... listview.setOnItemClickListener(new OnItemClickListener(){ public void onItemClick(AdapterView<?> parent, View view, int position, long id) { ... NetworkInfo ni = cm.getActiveNetworkInfo(); String connex = ni.getTypeName(); //Nullpointer exception here if(connex.equals("WIFI")doSomething(); } }); } }

  • setting up Google Webpage Optimizer where text and conversion pages are the same

    - by Lukich
    Hi. I have a site where both landing and thank you page are index.php page with different content loaded dynamically. As I'm generating the javascript and trying to validate it, it gives me an error saying that JS is not installed on the thank you page, which makes sense, because its content is not loaded yet. I was wondering how I can circumvent this issue? Any suggestions? Thanks! Luka

  • How to use wget to grab copy of Google Code site documents?

    - by Alex Reynolds
    I have a Google Code project which has a lot of wiki'ed documentation. I would like to create a copy of this documentation for offline browsing. I would like to use wget or a similar utility. I have tried the following: $ wget --no-parent \ --recursive \ --page-requisites \ --html-extension \ --base="http://code.google.com/p/myProject/" \ "http://code.google.com/p/myProject/" The problem is that links from within the mirrored copy have links like: file:///p/myProject/documentName This renaming of links in this way causes 404 (not found) errors, since the links point to nowhere valid on the filesystem. What options should I use instead with wget, so that I can make a local copy of the site's documentation and other pages?

  • Google app engine: Poor Performance with JDO + Datastore

    - by Bosh
    I have a simple data model that includes USERS: store basic information (key, name, phone # etc) RELATIONS: describe, e.g. a friendship between two users (supplying a relationship_type + two user keys) I'm getting very poor performance, for instance, if I try to print the first names of all of a user's friends. Say the user has 500 friends: I can fetch the list of friend user_ids very easily in a single query. But then, to pull out first names, I have to do 500 back-and-forth trips to the Datastore, each of which seems to take on the order of 30 ms. If this were SQL, I'd just do a JOIN and get the answer out fast. I understand there are rudimentary facilities for performing joins across un-owned relations in a relaxed implementation of JDO (as described at http://gae-java-persistence.blogspot.com) but they sound experimental and non-standard (e.g. my code won't work in any other JDO implementation). Is this really my best bet? Otherwise, how do people extract satisfactory performance from JDO/Datastore in this kind of (very common) situation? -Bosh

  • Custom event listener on Android app

    - by Bilthon
    Hi everybody, I need to set up a simple event listener to refresh a listview from once in a while. The problem is I don't know how could I generate an event. I know that for events like key or button pressing I just need to implement the handler. But in this specific case I actually need to generate the event, which will be fired everytime another running thread of my app wakes up and refreshes it's list of news from a rss feed. I've done everything, but got stucked in here. Can I get any suggestion or link with some more info on how to implement this? Thanks Nelson R. Perez

  • Android Content Provider database leak issue

    - by MattC
    I am writing a content provider for this application and in my content provider I am opening a database connection, running a query and returning the cursor of results to the calling program. If I close this database connection in the provider, the cursor has no results. If I leave it open, I get "leak found" errors in my DDMS log. What am I missing here? What's the clean, proper way to return a cursor of database results?
