Is there any way for an ordinary application to replace low level classes that are preloaded on startup, so that higher level preloaded classes will end up calling my custom versions rather than the originals?
I'm thinking the answer is no, but want to make sure I haven't overlooked something.

I was looking 2 weeks ago for sending back and home key events when on Click is performed on a Image Button, I could do that perfectly. I have a device with no buttons.

I got the following stack trace. code...

If I were to write an improved version of - let's say - TextView. Is it possible to make all app's on the system using this class, basically replace TextView? How are the java classes on the Android system, are they compiled, can I replace the library? Is this protected?
View 1 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.
I'm having trouble developing an app, while it works in API level 10, it does not in API level 7. I wondery why and I've been looking for a site that summarizes the differences, or the new features from one API level to another and cannot find it.

View 3 Replies View RelatedIs there a way to manage the audio levels through an app? Or is it more dependent on the phone's built in capabilities? Right now at work I listen to a skype audio call from my house (for security) at a very low volume and then at a higher level I listen to music or podcasts, both sources going at the same time. When my dog goes nuts, the door is knocked on, or (in theory) if someone busted down my door, I notice the change in volume and sound, turn off my local media, and focus on what I'm hearing until the drama passes.
I ask because I would like to continue this setup when not at work, like say while running, where I again have earphones in and am normally listening to audio content. I would like to be able to have two pieces of audio: music combined with a skype stream or normal phone call, going at the same time like at work. So is there a way to have two sources going at the same time, with the volume of each independently adjustable? Is this an app thing or a phone thing? Phone will be Sprint Hero.
Is there an app to replace the "Car Home" program that automatically opens when the Motorola Droid is placed in the car dock? It is bad enough that this screen comes up everytime you dock the phone in the car, but it is even more annoying that the "home" button is hijacked so that anytime you press it from any other program it takes you back to the "Car Home" instead of the main home. I would love to have an App that would allow you to designate a different program to open when in the dock, such as Quick Dial.

View 2 Replies View RelatedIs it possible to create a lockscreen replacement at the application level that replaces the device's security lock, whether it be PIN, passphrase, pattern or face unlock, or potentially a new method? I know it's possible in the framework level, and have done it before, but I'm just wondering if it's possible to do it at the application level.
So far the few lockscreen replacements that I've tried only implement a slide gesture unlock lockscreen UI, and falls back to the device's security lock after that.
But I have a couple of questions:
1. Replacement camera app? one that might load fast enough to actually snag a cool picture? one that lets you set where to save the pictures to?
2. Media Player / gallery app that lets you choose which folders to look in? I mean, it's funny as hell that my MOMENT gallery includes all the icon graphics from sprint navigation. So those there things there. can make my moment ROCK.

I am trying to determine how to structure the code of a simple android game I am writing. I am focused on the UI portion. The behind the scenes portion (like a pause/restart/switching/etc) does not concern me. The Android demo games source code already do a great job with this. Essentially my game will need a UI with a series of objects on the screen (roughly 100 or 10x10) that the user can interact with. I need to supply an image for each object as well as implement the touch events and animation events for each object. What I am wondering is what type of class do I use for each object so that I can successfully implement these methods and how do I implement that particular class. Note that this game only executes on a user interaction with one of these objects, meaning I don't need a "real-time" implementation.....
