android-homebutton

I've developed and app that is a slide show of pictures which each play a sound when you tap them. It's like a picture book for ages 2-4. The problem is, since android won't let you capture a home button press and essentially disable it, when parents give the phone to their child to play with unattended (brave parent), the child can inadvertenly exit the app and then make calls or otherwise tweak the phone. There are two other apps that currently have a psuedo fix for this issue. The apps are Toddler Lock and ToddlePhone. I've tried contacting the developers of these apps for some guidance but

for some specific requirement I am required to change Android Default Home application with my customized Home application ( a setting inside my app that will toggle default home = my application or previous home) I don't want the user to travel android settings that are very complicated. Can any one help me out like where it registers launcher.apk for default home application or how to change that The only thing I could find was that old question: How to change default Android's Desktop application? but no answers at all. I have seen HomeSwitcher in the Market that do the trick, but no answer

I know this question has been asked many times and the answer is always "No we cant disable home button". I have a little different query to ask. I wrote simple code in which my activity overrides the onKeyDown() and return true for all key presses. In theory this means whoever opens the application is stuck there and has no option to move out of the application. When i tested this application on different devices, i made following observations : On motorola device with OS as 2.2.2 , Home button got disabled. On HTC device with OS as 2.3.5 , Home button got disabled. On Sony with OS as 2.3.7 ,

As the question suggests I know we can't override the Home key event but if you look into the emulator of android 2.2 you will see an application Car Home it has overridden most of the keys like Home, end call. Now, the point is how have they done it? I tried to peep into the source code of the app but to my surprise its not available or I am unable to find it, but I don't think later is the case. I agree with @Romain Guy You can't override the behaviour of home button. What the Car Home app does: it has defined itself as a launcher. You can also define yours as a launcher, and it will be
