Authenticating against App Engine from an Android app - Nick's Blog - 0 views

  • Authentication with App Engine, regardless of where you're doing it, is a three-stage process: Obtain an authentication token. This can be done with ClientLogin for installed apps, for example, or with AuthSub for a webapp. When logging in directly to an application, this is the part of the login process where your user sees a Google signin screen. Take that authentication token, and use it to obtain an authentication cookie. Use that authentication cookie in all subsequent requests.

      Is it use to auto-fill the form on WebView?
    • Vincent Tsao
       
      JSInterface lets you bind Java objects into the WebView so they can be controlled from the web pages JavaScript, which means we can do anything to the content from webview via javascript interface, like what we can do with the html DOM content with javascrpit

Help getting array from arrays.xml file (Android, Eclipse) - Stack Overflow - 0 views

  • I am just trying to display a list from an array that I have in my arrays.xml.
  • String[] testArray = getResources().getStringArray(R.array.testArray); /** Called when the activity is first created. */ @Override protected void onCreate(Bundle savedInstanceState)
  • You can't initialize your testArray field this way, because the application resources still aren't ready.
  • ...1 more annotation...
  • protected void onCreate(Bundle savedInstanceState) {    super.onCreate(savedInstanceState);    // Create an ArrayAdapter that will contain all list items    ArrayAdapter<String> adapter;    mTestArray =  = getResources().getStringArray(R.array.testArray);        /* Assign the name array to that adapter and     also choose a simple layout for the list items */     adapter = new ArrayAdapter<String>(    this,    android.R.layout.simple_list_item_1,    mTestArray);    // Assign the adapter to this ListActivity    setListAdapter(adapter);    }}

Supporting Multiple Screens | Android Developers - 0 views

  • The density of a screen is important because, other things being equal, a UI element (such as a button) whose height and width are defined in terms of screen pixels will appear larger on the lower density screen and smaller on the higher density screen.
  • The density-independent pixel is equivalent to one physical pixel on a 160 dpi screen, the baseline density assumed by the platform (as described later in this document). At run time, the platform transparently handles any scaling of the dip units needed, based on the actual density of the screen in use. The conversion of dip units to screen pixels is simple: pixels = dips * (density / 160). For example, on 240 dpi screen, 1 dip would equal 1.5 physical pixels. Using dip units to define your application's UI is highly recommended, as a way of ensuring proper display of your UI on different screens.

Issue 1480 - android - Intent android.media.action.IMAGE_CAPTURE returns an image with ... - 0 views

  • On an HTC Hero, this EXTRA_OUTPUT doesn't even work. It doesn't put your picture in the file you specify, but it hands it to you thru a Mediastore uri. Apparently, the only way to get a full size picture is to do all camera handling in your app instead of using the IMAGE_CAPTURE intent.
  • I think Google have missed a trick on this one. They have defined standard intents for media capture, but not specified standard responses (ie. the "data" parameter in the onActivityResult Activity callback method). Other Android vendors (e.g. HTC Hero) have created their own Camera applications that handle the standard IMAGE_CAPTURE intent, but return different data & have different ways to save/return the image information. All I want is to be able to fire a IMAGE_CAPTURE intent from my own app, and get back a Uri reference to the captured image. Simple. I have no requirement to further manipulate the image .. I just need the Uri to store in my app's database for future reference.
