Method 2)
IHardwareService hardware = IHardwareService.Stub.asInterface(ServiceManager.getService("hardware"));
hardware.setScreenBacklight(.5);

Android :: Create A Proper Splash / Load Screen?

Jan 21, 2010

I have an application that uses OpenGL on a GLSurfaceView. The problem is that the initial load takes quite a while processing textures and getting things ready.

What i want to do is have a simple PNG displayed (with a slight animation) while the GLSurfaceView is getting ready. As soon as it's ready to render, i would like to tear down the splash screen.

What is the right way to do this? I've tried ViewFlipper, ViewSwitcher and a bunch of other things to switch between my R.layout.main view and my GLSurfaceView but i can't seem to get it right. Any ideas?

Android :: Proper Way Of Resizing An Image To Put In A Ldpi / Hdpi Screen?

Nov 24, 2010

What is the proper way of sizing the dimensions of an image in a hdpi screen vs a ldpi screen.

For instance, an 89*80 png displays fine, with the text, on my droid 2....but how should I go about resizing the image to be smaller on a smaller screened droid? Do I manually alter the image and place it in the ldpi folder or will it do that automatically?

Android :: How To Specify Proper Layout For View?

Mar 3, 2009

I want to re-use 1 adapter (similar to well known ImageAdapter from samples) with 2 different views - Gallery and GridView. I need to specify LayoutParams for the each View returned by getView() method of my adapter. In case of Gallery it should be instance of Gallery.LayoutParams, and in case of GridView it should be GridView.LayoutParams. I'll get an exception for sure if I'll try Gallery.LayoutParams with GridView and vice versa.What is the best way to do that? Can I somehow use "parent" parameter (ViewGroup parent) for that?

Mar 18, 2010

I have written an application and added 2 contacts on emulator, but i
am not able to update their names on android 2.1, code is working on
android 1.6 platform with the following code.

ContentValues contactValues = new ContentValues();
contactValues.put(Contacts.People.NAME, firstName+" "+lastName);
getContentResolver().update(UpdateContactUri, contactValues, null,
null);

In android 1.6 i am getting Uri for those two contacts are "content://
contacts/people/1" and "content://contacts/people/2".

but in 2.1 I am getting these values are "content://contacts/people/8"
and "content://contacts/people/9" and while updating its giving
"java.IllegalArgumentException, Empty values" exception.

When i tried to put a static Uri like "content://contacts/people/1",
code was debugged sucessfully but contact was not updated.

How can i resolve it, why i am not getting uri like 1.6 platform ?

Android :: Proper Video Formats And Settings?

Jun 5, 2010

I'm having a bit of trouble getting videos to play on my HTC Evo with Android 2.1. I have several videos that I play on my PSP, and work just fine. However, when I transferred them over to my Evo's MicroSD card and tried to play them in any video player, they only played the audio stream, and no picture was shown. I never had trouble getting PSP-formatted videos to work on phones before; they worked n my G1 just fine. I assumed that because the Evo and PSP even had similar-sized screens, it would be even more compatible. It sounds somewhat foolish when I type it out, but one could expect it to work. I have tried playing it in the stock video player, the Meridian player, and the Video Player app from the android market, and they all had the same error. The file is an .mp4; and, as I said, gave me no problems when played in the PSP's video player.

Here's the specifications on the video file:
Type: MPEG4
Video Codec: AVC
Audio Codec: AAC
Size: 25 MB
Length: 00:23:41
Width: 480
Height: 272
Aspect Ratio: 16:9
Data Rate: 99kbps
Total Bitrate: 147 kbps
Frame Rate: 23 fps

Android :: Understanding Proper Alarm Flow

Jan 11, 2010

the app I'm trying to implement allows the user to select a sound file (MP3 or WAV) to play at a specific date and time showing a dialog with a progress bar and an OK/Cancel button allowing the user to stop the playing of the sound file. I want it to behave something like the countdown apps I've seen or even the built-in alarm clock app. As I'm implementing this simple (I thought!) app, I'm trying to better understand the platform and make the application conform to the Android way.

As I've been writing the app, I learn more about how things are supposed to work on the Android platform. And here's where I'm getting a bit confused. During my attempts to get the alarm to fire and display, I'm learning that properly formed Android applications are not supposed to show dialogs as a result of a background service or broadcast receiver being invoked through Android's alarm service. Instead, I think, the app is supposed to use a notification on the status bar to alert the user. The user then has the option to look at the notification to see what the app is trying to tell them..............

Android :: What Is Proper Way To Close An Activity / Application?

Aug 28, 2010

I started to develope an application. When I wanted to close the application I clicked on the home screen, but the app is still playing in the background. Than I tried to click on the "back" key, but nothing happend, so I've created a key event listener for the 'back" key, and inside that method I wrote finish(); Now my app is closing but I think it's still running in the background, because when I go to "manage applications" I can still see it in the "running" tab, and if I press it, I see I can click on the "force close" to actually close the app. What do I need to do in order to really close the app without leaving it open (one way or another)?

Android :: Proper URL Response From Browser - But Empty Within HttpGet

Aug 19, 2010

I am writing an android application which uses a REST-based API on the server. So far the login works perfectly using HttpGet = I send the credentials, it sends me back a JSON response object containing session id or failure. I then moved onto using another get api (this one is passed the sessionid) and the response I get back looks like a valid one "200 - Ok" but the response body contains nothing - 0 text.

If I take the same URL and drop it into a browser, I get all the JSON text I expect displayed in the browser window. So what is the difference between a browser request/response and that of HttpGet? Any clues as to why my HttpGet might return a 'valid' nothing?

Android :: Proper Way To Share Data Between Lite And Pro Versions Of Same App?

Apr 27, 2009

Suppose you have an app with a lite version and a full version. The app stores some user data in SharedPreferences, and some data in a SQL database. If a user tests the app for a few days, generating data all the time, and then decides to switch to the paid version, how do you copy or share the data between the two? Some code examples would be appreciated - but for some reason I have a feeling this is much, much more complex than I hope.

Android : Proper URL To Get An Auth Cookie From A GAE Based Application?

Oct 12, 2010

I have an android app I want to connect to a Google App Engine based server. I can get the auth token from the AccountManager. It seems the next thing I am supposed to do is talk to an auth page to get a cookie. Following the awesome instructions here: http://blog.notdot.net/2010/05/Authenticating-against-App-Engine-from-an-Android-app
I think my url should be:

https://MYAPP.appspot.com/_ah/login?continue=http://localhost/&auth=CrAZYl000ngToken

but rather than a redirect, I get a 500 server error:

Error: Server Error

The server encountered an error and could not complete your request. If the problem persists, please report your problem and mention this error message and the query that caused it. What's up with that? What is the URL I am supposed to be going to? Or maybe I'm doing something else wrong?

General :: Android - SurfaceView Flickers And Sometimes Does Not Apply Proper Paint

Apr 3, 2012

The issue I am experiencing is that the SurfaceView I am using flickers. Once in a while, the objects I draw flicker and they change their size or colour.

It looks like that sometimes the application skips my calls to 'Paint.setColor()' and the one to 'Paint.setStrokeWidth()'.

I have made methods which change the used paint and then, in order to try to fix this issue, to set it back to the default paint values. Still the issue persists. I have also read that the problem might be due to the double buffering. Is it the case? I am using this code for the DrawingThread:

I also tried to use a dirty Rectangle to try to see if the issue can be fixed, but still nothing. [I might not have understood what it actually does.

Code:
class DrawingThread extends Thread {
private SurfaceHolder _surfaceHolder;
private CustomView _cv;
private boolean _run = false;

[Code] .....

I have read somewhere I should draw on a single bitmap and then draw the bitmap on the canvas. I have tried several times but I cannot manage to do so.

Sony Ericsson Xperia X10 :: Proper Camera Flash LED With Android 2.1 Update?

Sony Ericsson Xperia X10 :: 2.1 Android Keyboard Proper Name Word Suggestions

Nov 29, 2010

When I was using my x10 when it was only 1.6, when you typed a letter using the android keyboard, it would give multiple word suggestions (ie. i - is, it, in, etc.) which helped a lot. But with 2.1, if I turn it's word suggestions, it only provides me with proper names or contact names. Any way to allow 2.1 to use word suggestions other than these proper/contact names? I don't like the default keyboard. Can no one help? I don't think I'm the only one with this problem.

Android : Achieve Basic Layout In Droid With Proper Z-ordering Of Views?

Sep 14, 2010

How can I achieve the following layout in Android?

What I would like, is to have the 3 blue boxes top aligned in their view, and then I'd like to have the red box centered underneath the blue boxes, but so that when I animate the red box up, it slides underneath the blue box.

I have tried placing the blue and red boxes in different layouts, but as soon as I animate the red box up, if it goes outside the border of its layout, it disappears (I don't want the red box's layout to clip the red box, I want the red box to slide under the blue box so that the blue box occludes the red box.)

I have also managed to create this layout using a series of nested layouts, but because of the draw order, the red box always appears on top of the blue box. I attempted to use the bringToFront() method, but I found out that this only works on sibling views within the same layout. Unfortunately I can't get this type of layout while keeping all 4 views within the same layout. Any suggestions? (also, if anyone has better suggestions for the title of this question I'm all ears)
