General :: Scaling HTML5 Built App

Jun 6, 2012

I have created an HTML5 'app' with a width and height 480 x 800 to be used as an android app.

Plan is that this can be scaled down/up for other Android devices to fit screen.

The app runs fine, but it is not being scaled to my device screen size. I have to scroll up/down and left/right on the every screen.

I have tried nearly every variation of the meta viewport tag with no succes (in the index.html file).

General :: Reverse Engineering Non-built To Built Ready SD Extension?

Nov 27, 2013

I have done many of reverse engineering for other electronics in the past, Since Im new to android I was wondering before even wasting my time if is possible to port, or built a rom from sources or a phone thatis NOT External SD built in to a phone that it have the external sd built in.

Making it short can I try to reverse engineer the android code from a Nexus 5 (no ext_sd) to other device that have ext_sd built in?

If is possible where should I be looking to start trying making some development on this as I haven't done nothing close quite.

General :: Nexus 7 - HTML5 Only Browser

Sep 14, 2013

I entered the Android world with a Nexus 7 (2012) edition recently.

I create some webpages which I want to make sure that it works in HTML5 browsers. The way I go about the testing is, I first create the webpages in my laptop, copy the folder to my Nexus 7, and open the index.html in the browser.

Now, I heard that Google Chrome is a HTML5 browser. But I am unable to open my html file in that when I open it from File Manager. I tried Dolphin Browser, but it crashes the moment it opens.

So, is there any other HTML5-only browser I can use for this purpose?

General :: Device Navigation Softkeys Stay Lit During Stock Browser HTML5 Video Playback

May 30, 2014

I'm using the Note2 with the TW-based Digiblur rom and am having trouble when playing HTML5 player videos in the stock web browser. Any time a video plays, instead of timing out like they are supposed to, the navigation softkeys on the device stay lit while the video is playing. If I pause or stop the video, everything goes back to normal and the keys time out like they are supposed to. The problem is not present in any video player application, including the stock YouTube client.

Android :: Scaling Transparent Graphics In 2.0.1

Dec 13, 2009

I have some transparent graphics in my game. Up through 2.0.0 they have looked fined. Since Android 2.0.1 though, some parts of the fully transparent regions of the graphics are instead slightly opaque (e.g. a circular gradient that goes to 100% transparency will have a faint halo around it).

I have tried putting my graphics in ../raw/ but that did not help (as described at

I have also tried exporting the Adobe Illustrator graphics at 16-bit pngs (instead of 8bit), but that did not help either.

Android :: OpenGL Texture Scaling

Feb 18, 2010

I have a texture with 8 equally sized stripes that I am using as a wall with OpenGL. On my Nexus One it scales it properly However, in emulators and on a G1 (and probably on other hardware), it does not scale properly, as the stripes remain the same width, while the height scales as it should. Is there an option that I need to set that is set to default on my nexus one but not on other platforms?

Android :: Nine Patch Pre-scaling On Hdpi

Jan 5, 2010

I have some 9-patch images on my app, and they work great on the medium density. When I load the app on a High density emulator/device, these images look grainy. It happens only to 9-patch images. The others look great after the pre- scaling. Is there a way to make them look good after the scaling, like the non-9-patch images?

Android :: Avoid Scaling Of Background

Oct 15, 2010

In a start activity of our android application we're using a linearlayout with an background image for whole space. The image size is 320x480 - the same as device resolution, we're using for testing. The problem is, the image will be scaled und looks not so nice. I tried to use imageview instead, but I've got black borders.
Some ideas, how to avoid scaling or how to get the proper size for background image?!

General :: Built A Custom Kernel For Phone

Apr 26, 2012

I'm trying to make a custom kernel for the Samsung Gravity SMART using sources from the unofficial CM9 port for the Gio/Ace (which both use very similar hardware to the Gravity Smart). What I've succeeded at so far:

1) Acquiring the source, both for the CM9 kernel and for the stock Froyo kernel
2) Searching for the device-dependent references in the stock kernel
3) Porting those changes over to the CM9 kernel
4) Getting everything to actually compile
5) Acquiring the stock CM7.2 source
6) Creating device makefiles (i.e., etc)
7) Building CM7.2 using kernel built in step #4
8) Putting the various img files into an Odin-compatible .tar.md5
9) Actually flashing to the phone.

And for all that work, I got.. a soft-bricked phone (fortunately, I have an Odin file for stock firmware). The phone boots to a SAMSUNG logo (not flashing/throbbing). how the heck do I figure out what's actually failing? Is there a bootloader to unlock, and if so how do I unlock it?

General :: Built-in EQ For Android Bluetooth Stack?

May 18, 2012

Does Android use a built-in EQ or limiter on their Bluetooth stack? I am running into a situation where both of my android phones, One X and Nexus One, have developed a "clipping" noise when I listen to music through the Bluetooth in my car. This same clipping doesn't happen when I listen to podcasts, only music. My assumption is that something in the framework is clipping the audio saying that it is too loud and causing this to happen.

I have also used the same Bluetooth setup my WP7 phone, an HTC Titan, and I do not hear this same noise at all. I have only heard this through my android phones which leaves me to believe that it is something based in OS level and not the Bluetooth set up itself.

Android :: Image Scaling By BitmapFactory.decodeResource()

Sep 17, 2009

I can't wait to try out the new 1.6 goodies, but first I'm retargeting my existing applications, and I decided to start with Daisy Garden. Changing to android:targetSdkVersion="4" caused the application to segfault on startup and discovered that the BitmapFactory.decodeResource method now performs scaling based on screen density. In this case the behaviour is unwanted - I'm loading a set of masks that are scaled later during composition. So I've quickly inserted the following method, which seems to perfectly mimic the previous behaviour:

private Bitmap loadBitmap(int resId) { BitmapFactory.Options options = new BitmapFactory.Options(); options.inTargetDensity = 1; options.inDensity = 1; return BitmapFactory.decodeResource(context.getResources(), resId, options);

Android :: WebView Not Respecting Scaling Percentage

Jun 11, 2010

I have a WebView which I'm trying to have scale to a certain percent on loading the page. The iPhone version of this software uses the HTML meta-tag:<meta name="viewport" content="width=320, initial-scale=0.95, maximum-scale=2.0, user-scalable=1">..Since Android's WebView doesn't seem to respect that tag I hard-coded the percent using setInitialScale(). However, the WebView is just flat-out ignoring this method call. No matter what number I put in there it shows at 100%.

Android :: Scaling Web Page In WebView Element

Nov 30, 2009

I'm loading a URL into a WebView and I'm having difficulty setting the "scale" of the web-page. Specifically, the web-page is too big (800x600) for the screen, so my thought is to use "setInitialScale(50)" to reduce the size. Here is some sample code that doesn't work (i.e. the web-page doesn't scale to 50%)

WebView wv = (WebView)findViewById(;
I also tried switching the order of the function calls but I get the same resultŠi.e.,
WebView wv = (WebView)findViewById(; wv.setInitialScale(50); wv.loadUrl("");

As an alternative, I have tried to use the "zoomOut()" function like this:
WebView wv = (WebView)findViewById(;
wv.loadUrl(""); wv.zoomOut();
This approach works for a split second, and then the image reverts to its original size.

Here is my content view:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android=" android"
android:orientation="vertical" android:layout_width="fill_parent"
android:layout_height="fill_parent"> <WebView android:id="@+id/webview"
android:layout_width="fill_parent" android:layout_height="fill_parent" /> </LinearLayout>

Android :: High Quality Image Resizing / Scaling

Nov 17, 2010

I need to scale down images coming from a Network stream without losing quality. I am aware of this solution Android: Strange out of memory issue but it is too coarse - inSampleSize is an integer and does not allow finer control over the resulting dimensions. That is, I need to scale images to specific h/w dimensions (and keeping aspect ratio). I dont mind having a DIY bicubic/lancoz algorithm in my code but I cant find any examples that would work on Android as they all rely on Java2D (JavaSE). EDIT: Ive attached a quick source. The original is 720x402 HD screen capture. Please ignore the top 2 thumbnails. The top large image is resized automatically by android (as part of layout) to about 130x72. It is nice and crisp. The bottom image is resized with API and has severe artifacting. Code...

Android :: Game Development Scaling - Texture And World

Jun 26, 2010

We're looking for a method to properly scale our textures and world. The current method we're using is having an arbitrary world unit which calculates the screen resolution and receives the size of a pixel on all resolutions. However is there an easier way of implementing a scaling method for game development? We have looked through dip and other android native elements but these don't work as well for a larger scale on game development.

Android :: Scaling Game Images According To Display Sizes

Jan 6, 2010

I developed a game with the g1 in my mind. Now I want to support large screen sizes but I don't want to add in the apk different images for different screen sizes because now the apk is 3mb and when installed thought market it became 6mb (due to protection on). If I have to double the images to support new screens, the apk would be too heavy (about 13mb, I think) so I'm wondering to know if scaling images at runtime by myself (without compatibility mode) maybe the best way for supporting larger screens. Compatibility mode does a great work in scaling images but it slows down drastically the frame rate (I think because the scale operation is made every time an image is used/moved and not only once on the load of the image itself).

Android :: Scaling - Animating Camera Preview Surface

Sep 20, 2010

I am using android.hardware.Camera to get a preview and display it on a custom SurfaceView that implements SurfaceHolder.Callback.

I am trying to zoom in to the camera preview surface by a specified scale (not using the camera's digital zoom) but I can't seem to find a correct way to do it. I also need to be able to zoom out and scale down the preview.

I was hoping to be able to do this using a ScaleAnimation but it doesn't seem to work on SurfaceView, nor the FrameLayout containing the SurfaceView.

I also tried setting the size of the SurfaceView using setLayoutParams but that doesn't seem to work too well on various hardware and it would be tough to animate smoothly.

How to achieve this effect? Right now I am starting to think I might have to implement this using GLSurfaceView but I'm very unsure.
