I have heard that a processor without graphics card will take a lots of time to produce a graphical entity,than one with graphics card. So is there anything like that if we use Open Gl in android application?
will my application become slow?

View 1 Replies View RelatedI know the Android SDK provides many Sensor class to use to get data or do something. I already verified my driver of sensor to get data successfully under linux kernel-2.6.29 I use I2C protocol to communication with my device, so I put sensor code under drivers/i2c/chips NOW I want to add my sensor into Android and I hope to link Android Sensor class with my device to reduce develop my application. How to do for this goal? Could I need to modify application framework or Libraries or another driver type for new device? I big your help
View 3 Replies View RelatedI want to reduce the file size of my application in the market. The strange thing is that my application "LeonardFrog.apk" just uses 4mb but the Google-Market shows me that it uses 8mb. You can search for it (Leonard Frog Beta) in the market. How can this be???
In my application, there are many images and long sounds. My folder "res" just uses 3,7mb and there is nothing else in my game beside the quellcode. So WHY is the size of my game in the market 8mb?
I'm working on a Java Android game. Games here generally need to use memory pools to avoid garbage collection.Making use of subclasses is a pain when using memory pools as you need to e.g. say how many Roamer and Chaser objects you want upfront and not just how many Enemy objects you might need.I would then have an update function that checked the "type" variable and updated accordingly. This is obviously a more C-like approach. It feels hacky though because e.g. a roamer enemy will have a "target" variable it never uses. I'm unlikely to have more than a 100 enemies in memory at a time though so it really isn't a big deal memory wise. I just want some compromise between nice code and speed.Does anyone have any comments on how best to structure this? Is merging classes like this going too far? Is this ever a good idea? Should I just use a regular class tree?

View 1 Replies View RelatedAfter reading the thread on here about not needing a task manager, I removed mine and downloaded system panel just to keep an eye on whats always running and be able to kill any rogue apps. However, whenever I open system panel lite, its only ever the one that seems to be using the most CPU in the foreground apps, with it having the most bar full on the left. So what I'm confused about is that whether its normally just using a lot of my CPU to keep track of things, in which case I should uninstall it, or whether its a case of it showing up as using so much because I am using it at the time of checking to check the CPU usage.

I am just putting this question out there.
Is there a large efficiency difference between Canvas.drawBitmap or OpenGL. I am drawing using Canvas.drawBitmap and running slowing FPS, would openGL speed that up a lot you think?
Android should become more like Windows. Android should be able to detect and recognize the different hardware configurations and adjust itself accordingly. This way, you hit two birds with one stone. No more fragmentation. No more differences in the UI, Custom UI will be entirely optional.
All the manufacturer has to do is make the hardware and provide the hardware drivers to Google. Simple as that. Everything will be so much easier. Phone manufacturers will be able pump out devices like crazy without any worries. Software developers won't have to worry about device compatibility. Come on Google, lets do it.

I have installed ADB and the whole Android SDK to root my asus transformer infinity (tf700t). I have taken all the steps every forum on the web describes: installing everything trough the manager, adjusting the path in the System Variables, and finally it getting it to work together with my tablet. However, when I try to flash/copy/install files from my folder (yes these files are in the same folder as adb.exe and fastboot.exe, which is the folder I used in the System Variables) It can't either find these files or it cannot open these files. When i put in the command 'path' however. I does give me the path where the files can be found.

I need to know how I can create an Intent to open MyTracks or any other application that I don't know what intents they listen to.
I got this info from DDMS, but I havn't been succesful in turning this to an Intent I can use. This is taken from when opening MyTracks manually.
I understand how to use intents and startActivity() when opening another activity within my own app, but how do you start a different app? specifically:
- How do you determine if the user has the needed app installed on their device?
- How do you start that app?
- How do you pass parameters to that app?
- How do you find all this info out for a specific app (say Adobe reader, or google maps)?
Is there any one know how to open an App when the Android OS start up, I have to do it in an embedded system?
View 4 Replies View RelatedFrom this article:
http://developer.android.com/guide/publishing/publishing.html#marketintent
Android Market could be invoked by an ACTION_VIEW intent with URL like
http://market.android.com/details?id=<packagename>
How does it work? Is the market.android.com return some info to browser to help it open the Android Market application? or just the browser locally does the trick? Is it possible to set up an open URL who could do the same thing? For example, I have an app called MyBooks(com.mybooks.app) and a site like:
http://www.mybooks.com
an url could be
http://www.myboos.com/details?id=0001
And when Browser opens this url, the site will return some kind of pre-defined response, which might contains an Intent action string, like "com.myboos.app.action.VIEW" and the queried id 0001.
Browser could then try to start an Activity using that action
"com.mybooks.app.action.View",
if there is an Activity for that, start it and pass the id in. If not, it tries to connect another URL like
http://www.myboos.com/details?id=0001&installed=false
Is this possible to work on any version of the Android?
I am wondering if it is possible to intercept an open application call, for any (most of the) installed application. Or at least for opening the Activity having the intent-filter's action set to Main (if it exists for an app).

View 6 Replies View RelatedGreetings. Years after reading the GTD book and trying all sorts of apps and methods, I still can't find myself settling for a todo system that's simple and effective using my phone. I'm always looking for threads and articles on task managers, but most are only people spouting "I use generic todo app xyz and it rules!" Never how they practically use it in their daily lives. So, I'm asking all of you: what apps do you use for tasks and maybe even reference systems, and HOW. This might be useful for all procrastrinating couchpotatoes like me. Right now I'm using something very simple: Mobisle Notes, with 2 lists: a sorted "Inbox" which is basically just all tasks that come to mind (Sorted as in, priority first, then due date, then projects, then random stuff) And a today list with 5 actions I want to do today. Far from perfect, and Mobisle doesn't handle tags and moving of tasks from list to list a hassle, which keeps me on the lookout.
View 6 Replies View RelatedI would like to run multiple instances of same application for dev purpose. How does app define it's name in the system, through which of the files is that configured.
View 3 Replies View RelatedI came across this today and was wondering does this work in production app or does it merely work because my phone allows non market apks.
Here is an example, Take a class like, android.view.IWindow, and copy it's source into your project and recompile it after changing a few things. (Don't rename or repackage it).
Now when your APK loads in the VM, something odd happens.
CODE:...
So the logging is a little ambiguous, but is it saying that the classes in this APK are blocking out previous versions and that these new classes aren't being verified. If so I hope this is only succeeding because as developers most targets are in development mode when allowing non market apks (non rooted phones). However does this work in market released apps as well? This seems like a really nasty security exploit if I can override system interfaces just for my application.
