By default in my apps the back and menu buttons are not working, also the long press of the search button doesn't work. This only happens in my apps and it doesn't work either on my desire hd, emulator or galaxy nexus (software back button).
What could be the problem?
Is this happening only to me?
To make the back button close my application i have to hardcode it

I have a Samsung Galaxy Note. I was downloading a pdf file and after that my tablet is acting weirdly. Whenever I turn it off and back on, the screen would be unresponsive except for the back button and power button. Restarting doesn't work. Sometimes, when there is a prompt like choosing a browser, it sends me straight to the browser. When I go back to the home screen, everything works until I turn it off and back on again. I wonder whether I don't have to factory reset my device to solve the problem. Thanks for your suggestion.
Try resetting cache memory (reboot+shutdown button + upper button (normally)).
That may help
I am making one lock application and for that I need to disable home button. I already tried all the common solutions available and it works for other android versions but for this device which is running on Android 4.2.2 it fails always.
You can't disable the home button as it can cause security issues promoting malicious apps etc.
What you can do is add an overlay to your app instead that will cover over other apps.
See this link for more info:How to disable Home and other system buttons in Android?
Make application as launcher.
First time when home button is pressed, device ask for choose launcher, select your applicaiton with always options.
From the next time when application is opened and you press the home button app never go in background.
I have a problem with the Phonegap Android application with the back button in some Android devices.
In the Pic when I press application's back button(Red color button), it is not working and the phone's home is working. This is in particular of some Android devices which is having the hardware buttons in main screen.
Now the question is how to stop the phonegap application before the hardware buttons. Means I wat to stop the application top of those device buttons, because I need those buttons also for the application
My application works fine on samsung, sony erricson and emulators.. but when i checked on droid x, the home button works weird.
Usually on clicking on the home button, current app has to run in background, but in droid it is exists and when i start the application again from menu, it starts from the beginning but not from where i left the application.
Do i have to do anything in coding? i tried handling the home button myself, but after reading the document, it says home button can not be used in applications. Is there any way to do this? please help.. Thank you..
When your app looses focus it should execute onPause() and only be removed aka onStop() if the phone is short on resources. The other apps installed on the phone can have a big impact on how your app might behave with regards to this. If your app is resource hungry that would also be the variance on disparate devices.
On my droid phone, I get what I consider a proper pause/stop/resume/restart sequence when the home button is pressed and I then select my application. However, I'm testing on a new Samsung Galaxy tablet and when I select my application after having pressed the home button, a new activity is being launched. I do not understand why the behavior is different on the Galaxy. Any ideas? I have removed orientation config changes in the manifest, so it's not that.
