    - by keithwarren7

  • Android @Override usage

    - by BahaiResearch.com
    (Newbie to Java, old time C# guy.) I have noticed a lot of the use of @Override in Android example code. I thought that all Java methods were by default "Virutal"? What then does @Override do? Example: private class HelloWebViewClient extends WebViewClient { @Override public boolean shouldOverrideUrlLoading(WebView view, String url) { view.loadUrl(url); return true; } }

  • Is Android a product line?

    - by geowa4
    Android is an open source operating system that is modified by cell phone vendors (HTC, Motorola, etc.). Modifications include the user interface, drivers, and other proprietary extensions. Traditionally, product lines have been a suite of products or services that share a core set of functionality and are modified for different domains and markets. Does this still qualify as a product line?

  • Help me choose between XML or SQL Lite on android

    - by Ngetha
    I have an android app that periodically, say once a week downloads content from a server in XML. The content is used by the app, different Acitivities use different parts of the content. My question is a design one, should I save the data in SQlite or just keep it as an XML file, which one would be faster to read? The app can only use one content piece at a time, which means subsequent XML content downloads replace the old one.

  • How can I keep the Windows 8 virtual keyboard from popping up?

    - by orbfish
    I am the unwilling recipient of Windows 8. Lenovo couldn't fix the new Windows 7 Ultrabook I bought, so they sent me a Yoga laptop, with touch-screen and Windows 8. Once I bought a start menu replacement, I don't mind Windows 8 too much - it's ugly, but most things work as well as Windows 7. But the thing that drives me crazy, endlessly, is the virtual keyboard popping up when I'm trying to do something else (well, just about anytime, since I almost never use it to type). It's like a giant Clippy that covers half the screen. I haven't figured out what causes it to pop up. It seems pretty random, and sometimes it goes away before I can even reach for the escape key. Sometimes it comes up when I'm typing, sometimes when my hands are nowhere near the keyboard. Sometimes several times a minute, sometimes not for hours. Any suggestions?

  • How to change sync settings through Android API?

    - by Kyle Slattery
    Is there a way to change the sync settings of a Gmail account programmatically with an Android app? For instance, I'd like to enable/disable syncing of a Gmail account from my app, without the user having to do anything. I took a look at AccountManager, but that doesn't seem to be the right place to look.

  • The Relationship Between Activities and View Objects - Android

    - by Greenhouse Gases
    I am attempting to learn how to develop on the Android platform but do not quite understand the relationship between Activities and Views, because according to the documentation an Activity is link to a UI object that the user can interact with, but if this is the case where does the whole idea of Views come in? There is probably a very basic explanation but I would appreciate a few pointers all the same. Thanks

    What would be the best way to write an app for the iPhone OS and the Android OS that allows access to a web blog (posted on blogspot.com)?

  • How to blit() in android?

    - by Lo'oris
    I'm used to handle graphics with old-school libraries (allegro, GD, pygame), where if I want to copy a part of a bitmap into another... I just use blit. I'm trying to figure out how to do that in android, and I got very confused. So... we have these Canvas that are write-only, and Bitmaps that are read-only? It seems too stupid to be real, there must be something I'm missing, but I really can't figure it out.

  • What is an Automated way to Access a Virtual Machine's Webserver from its Host Machine? [closed]

    - by Jonnybojangles
    As a Web-Developer what is the most efficient (automated) way to connect to a Virtual Machine (VM) running a development webserver from it’s Host Machine (the machine running the VM) when you do not have control over the networks (home, Startbucks, work, etc) you are connected to? Currently I start my VM (a VirtualBox VM running CentOS), run ifconfig to determine the VM’s current IP. I then take that IP and map it my Host machine’s host file so that I can access the VM’s webserver from the Host. I feel that this is not an efficient way to connect to my VM’s webserver because each time I connect to a new network (a few times a day) I need to repeat the IP look up and host file update, and sometimes restart the VM's network service.
