• Android - Fail to connect to camera

  - by teepusink

  Hi, I'm using the Android APIDemo sample code. When I run the CameraPreview example, at first it was giving me an error. (http://stackoverflow.com/questions/2556389/android-camera-functionality-howto) I traced that one down and the sample was working for a while. Now, it no longer works. It says ERROR/AndroidRuntime(2949): java.lang.RuntimeException: Fail to connect to camera service What can be causing that? It happens when camera.open() is called. Thanks, Tee

In other words, is it possible to do something like: public View getView(int position, View view, ViewGroup parent) { // calculate viewID here if (view == null || *view is not null but was created from different XML than viewID* ) { view = mInflater.inflate(viewId, null);

• Android NDK - does it support straight ARM code or just Thumb

  - by Russell Kay

  All, I have been asked to evaluate the Android platform for our product and I am looking at various options, I am only just scratching the surface just now and the one thing that is bothering me is that I cannot see how to compile code as straight ARM code (no Thumb), I know that Thumb runs slower and we will need the performance in key sections of our code. I think it should just be setting the -march flag in the LOCAL_CFLAGS of the Android.mk file, but I cannot get that to work... Can anyone help. Russell

• How to get bluetooth RSSI on android after discovery

  - by Karthik Ganesan

  I'm trying to write a program that can read the signal strength of a bluetooth device linked to my android 2.0 handset. Doesnt seem like android exposes anyway to get the RSSI unless it is during discovery. Is there any other way to get the signal strength of the device after the device has been detected? I read of a way to do it using NDK to access the underlying BlueZ API, but I dont know how to use that. Any help would be appreciated.
