  • 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!

  • 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.

  • 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?

  • Running my web site in a 32-bit application pool on a 64-bit OS.

    - by Jeremy H
    Here is my setup: Dev: - Windows Server 2008 64-bit - Visual Studio 2008 - Solution with 3 class libraries, 1 web application Staging Web Server: - Windows Server 2008 R2 64-bit - IIS7.5 Integrated Application Pool with 32-bit Applications Enabled In Visual Studio I have set all 4 of my projects to compile to 'Any CPU' but when I run this web application on the web server with the 32-bit application pool it times out and crashes. When I run the application pool in 64-bit mode it works fine. The production web server requires me to run 32-bit application pool in 64-bit OS which is why I have this configured in this way on the staging web server. (I considered posting on ServerFault but the server part seems to be working fine. It is my code specifically that doesn't seem to want to run in 32-bit application pool which is why I am posting here.)

  • How can I "slide up" a view on android from the bottom of a screen?

    - by Jakub Arnold
    I'm trying to make a really simple slide up list view, which is displayed when a user clicks on a button at the bottom of the screen. Here's how it should look: And a complete implementation in HTML/JS http://jsbin.com/utAQOVA/1/edit I've tried to use RelativeLayout to position the list just below the button, and put that whole thing into a wrapper and then animate that up/down (same as in the JSBin above). The problem is that the bottom part which isn't visible in the beginning is somehow clipped, even if I slide it up. Evern if I initially show a portion of the list as the screenshow below shows, the bottom part gets clipped when it moves up and only the part that was initially visible is displayed. What would be a proper approach to do this kind of animation? Here's a relevant portion of the layout

  • How is the Viewflipper handling the back button in Android?

    - by Janusz
    I'm thinking about using a ViewFlipper for an Wizard like Activity. But I see one problem with this approach. The back button. Will the back button go back to the last shown activity or will the the Viewflipper somehow catch the back button event and only change to the last shown activity? I suspect the ViewFlipper to be treated as one Activity on the BackStack so is seems that is the wrong aproach for a wizard. Is this correct?

  • Android: setting up a google map class. bit of advice required.

    - by Capsud
    Hey there, Ok so this is what i've got. Button anandabutton = (Button) findViewById(R.id.anandaAddressButton); anandabutton.setOnClickListener(new View.OnClickListener() { public void onClick(View view) { Intent myIntent = new Intent(view.getContext(),MapClass.class); startActivityForResult(myIntent,0); } }); This method opens up my MapClass class which at the moment I just have set to show the location of one place. But I have a load of buttons and rather than making a lot of different mapClass classes for each button, I am wondering can I just use the one class and depending on what button 'id' is pressed, it will check an 'if statement' and then put in the correct coordinates into the method to display the map. It would be a lot neater than coding up like 20-30 classes. I'm not sure if i've explained that right so if not let me know. Thanks for any help.

  • how to preform an activity at the android lock screen?

    - by John
    I would like to perform an activity at the key guard screen, but the only way I can find to do so is to disable the key guard, do my activity, then re enable the key guard. This would be ok if it didn't cause the key guard screen to flash off and on (disable makes it disappear then re enable brings it back). I am wondering how I can perform an activity with it still being displayed? Kinda like how when the alarm goes off it shows a pop-up which is displayed over the key-guard screen?

  • Android: how can i tell if the soft keyboard is showing or not?

    - by binnyb
    Heres the dilemma: I am showing a screen with 3 input fields and 2 buttons inside of a tab(there are 3 tabs total, and they are on the bottom of the screen). the 2 buttons are set to the bottom left and right of the screen, right above the tabs. when i click on an input field, the tabs and buttons are all pushed up on top of the keyboard. i desire to only push the buttons up, and leave the tabs where they originally are, on the bottom. i am thinking of setting the visibility of the tabs to GONE once i determine that the soft keyboard is showing, and visibility to VISIBLE once the soft keyboard is gone. is there some kind of listener for the soft keyboard, or maybe the input field? maybe some tricky use of OnFocusChangeListener for the edit text? How can i determine whether the keyboard is visible or not?
