In my Activity's onCreate I do the following and it works fine. theStatus = (TextView) findViewById(R.id.theStatus); theStatus.setText("w...

I just discovered today, though, that the Android JSON API doesn't include a remove() option. Huh? Do I have to dump the array into another collecti...

Whilst it was in the "Just In" section I was seeing decent download numbers, but since then interest seems to have dropped off significantly. I think now people can only find my app through a specific keyword search, which doesn't make me particularly confident about it e...
I'm wondering how the UI of e.g. Opera Mini, Adobe Reader or the new Twitter application is made on Android. Both of them use very different looking controls than what the OS provide in default.

Hi, I (as a complete JS newbie) am trying to port a Greasemonkey script to Android. The only problem so far seems to be the call to GM_xmlhttpRequest or XMLHttpRequest (the script tries to use one of them according to the browser it detects). Is there any known alternative API on the android browser? Thank you in advance! ...
I defined static variables in Activities in order to pass complex data between Activities. Many people suggest not to use any static variables in Android. Some people suggest to store global data in a custom android.app.Application. I don't think there is any difference between static variable and custom Application. I'd like to know y...

The user may place multiple instances of this widget on their home screen. What would be the best way to maintain the unique configuration states on each of the widget instances? Or woul...
I need help understanding the following. Say I have a display that is 854x480 pixels. Why is it that the MotionEvent.getX and getY methods return floats? As far as I can tell, the pixels on the display are discrete integers, there is no such thing as a half a pixel on the display. ...
