• Can Android OS be programmed to interface with a external device via the mini-USB port?

  - by user322865

  Basic example, if I bought a chipset with a light socket and bulb soldered to the chipset; then put a USB cable with the mini-USB plug on the end to get plugged into the android phone. Can I write a Java application to turn on/off the light, get the status of the light(on/off) and maybe power a super-small led/bulb with power from the phone itself? Any insight at all would be greatly appreciated. Thank you

• Turn Bluetooth On and Off in Andriod 1.5 (SDK level 3)?

  - by pcm2a

  There are tons of pay and free bluetooth toggles on the market that work with Android 1.5 (SDK level 3). The problem is there is no visible API for this! Does anyone have any working code snippits on how to enable and disable bluetooth that works on Android 1.5? I assume you must have to use some kind of reflection for it. There are some examples over on anddev.org, but they only work with Android 1.1 or lower. This is for Android 1.5 (SDK level 3) and not Android 2.0 or greater. In Android 2.0 or later Google added easy to use APIs.

• No pre-built ActionBar for Android pre-3.0?

  - by Ollie C

  I note the release a few days ago of the static library bringing fragments to Android versions prior to 3.0, but does this library include the ActionBar? I suspect not. I assume that for an app that will work on pre-3.0 versions, that it needs a hand-built ActionBar implementation for versions up to 2.3 and then to use the OS default ActionBar in v3.0? for some reason I assumed the library had ActionBar in it, but as I dig further I'm not finding any evidence of its presence.

• How do I update the system wallpaper in an Android 1.6 service after changing it with setWallpaper()

  - by Majakk

  So basically the code "almost" works - the problem is that the system does not appear to know that the system wallpaper have been changed or does not do anything about it. Starting and closing another app manually appears to enforce an update. In an event call the following is done: getApplicationContext().setWallpaper(pWallOne); Is there some way of telling the android system to update the graphics or to do some cheap trick that forces it to? Any help or tip would be very much appreciated!!
