    Hi guys, In my application I use SoftReference to cache images, it is working fine with active internet connection. And now I need to cache images, so I could use it in offline mode. What is the best way to implement it? Use complex solution with SoftReference and database? or maybe SoftReference and local storage (sdcard)? I would appreciate your advices. Thanks.

  • How to debug an App on Android with GDBSERVER?

    - by cjserio
    I'm trying to debug a native shared library that my App uses through JNI. I can attach to a running app just fine with "gdbserver --attach pid" but i need to actually launch my app when i launch the gdbserver command. There's a million blog hits on this topic but none of them seem to be clear as to how you launch your app. They all say to just type "gdbserver 10.0.2.2:1234 ./MyProgram" but what exactly is "MyProgram". Is that MyProgram.apk? Is it MyProgram.so? Is it some other file that gets created when the app is installed? If so, what's its path?

  • How to change object positions in an android layout?

    - by Pedro Santos
    Hi, I'm currently working on a very simple aplication, and I intended to make it change the visual aspect depending on the screen size. The application just has 6 buttons like this: http://www.freeimagehosting.net/uploads/e1efb4c4d0.jpg I'm using the AbsoluteLayout, and changing the x and y of the buttons with the methods offsetLeftAndRight and offsetTopAndBottom. I'm not changing the layout of the buttons in the xml file, so the all start in the same place. However, if I use this methods inside the onClickMethod they sometimes appear where I want them, sometimes don't (can't figure out why), but if i use them in the onCreate method, nothing happens. Can someone point me in the right direction? Thanks

  • How can I display a dialog box for making a choice before a CALL is processed in android?

    - by jsight
    I would like to intercept outgoing calls and pass them to a VOIP application. I see that the Google Voice application has a feature for displaying a question before each call is actually initiated. It provides the user with the choice: Initiate call via Google Voice Initiate call via standard call I would like a way to do something similar with my application (so that not all calls have to be routed through it). At the moment, I can intercept CALL events via a BroadcastReceiver, however, these are not allowed to open dialogs (thus making it possible to display the choice). What is the best way of achieving this goal?

  • Android: I uploaded my first app! Keywords?...

    - by Allan
    I've just uploaded my first app on the market. It all went and looks well. I tried a few keywords to search for it, words that I also have in my description AND promo text, but some words don't find my app, some do. How does the keyword strategy work for an app on the market, I couldn't find no documentation on it.

  • Android Nexus One - Can I save energy with color scheme?

    - by Max Gontar
    Hi! I'm wondering what color-scheme is more energy-saving for AMOLED display? I've already decided to manage c-scheme according to ambient light, thanks to this post: Somewhat-proof, the link posted by nickf: Ironic Sans: Ow My Eyes. If you read that in a well lit room, the black-on-white will be the most pleasant to read. If you read it in a dark room, the white-on-black will be nicer. But if I want to save battery power, should I use bright content with light background or vice versa? Is it possible anyway (they say it's not)? Thanks!

  • How to insert a SQLite record with a datetime set to 'now' in Android application?

    - by droidguy
    Say, we have a table created as: create table notes (_id integer primary key autoincrement, created_date date) To insert a record, I'd use ContentValues initialValues = new ContentValues(); initialValues.put("date_created", ""); long rowId = mDb.insert(DATABASE_TABLE, null, initialValues); But how to set the date_created column to "now"? To make it clear, the initialValues.put("date_created", "datetime('now')"); Is not the right solution. It just sets the column to "datetime('now')" text.

  • Android - How can I upload a txt file to a website?

    - by Donal Rafferty
    I want to upload a txt file to a website, I'll admit I haven't looked into it in any great detail but I have looked at a few examples and would like more experienced opinions on whether I'm going in the right direction. Here is what I have so far: DefaultHttpClient httpClient = new DefaultHttpClient(); HttpContext localContext = new BasicHttpContext(); private String ret; HttpResponse response = null; HttpPost httpPost = null; public String postPage(String url, String data, boolean returnAddr) { ret = null; httpClient.getParams().setParameter(ClientPNames.COOKIE_POLICY, CookiePolicy.RFC_2109); httpPost = new HttpPost(url); response = null; StringEntity tmp = null; try { tmp = new StringEntity(data,"UTF-8"); } catch (UnsupportedEncodingException e) { System.out.println("HTTPHelp : UnsupportedEncodingException : "+e); } httpPost.setEntity(tmp); try { response = httpClient.execute(httpPost,localContext); } catch (ClientProtocolException e) { System.out.println("HTTPHelp : ClientProtocolException : "+e); } catch (IOException e) { System.out.println("HTTPHelp : IOException : "+e); } ret = response.getStatusLine().toString(); return ret; } And I call it as follows: postPage("http://www.testwebsite.com", "data/data/com.testxmlpost.xml/files/logging.txt", true)); I want to be able to upload a file from the device to a website. But when trying this way I get the following response back. HTTP/1.1 405 Method Not Allowed Am I trying the correct way or should I be doing it another way?
