I read somewhere that body temperature can be measured through touch screen since different body temperature induces different charge on the capacitive screen.Is it possible? If yes,how can the value be recorded and converted to corresponding temperature?
Different charge for device means different coordinates. So you can't say exactly - is it temperature changed, or user just move his finger.
Actually, charge doesn't depends on temperature so much.

Please help me how to implement this idea.
You can use animation to to show falling color objects. You can follow this link to view of this type of animation:-

Hi Can anyone help me with any links or hints on how I can achieve the following.
I need to be able to plot lines based on the touch event by the user from the center of a pie chart/circular image. I am a little familiar with aChartEngine, but not able to figure out how I can do it. I also need to store the XY co-ordinates so that I can reproduce it at a later point in time (the graph/image size will be different). So my XY points from the touch events should be from the center of the graph/image. Any leads/hints/links will be really helpful. Thanks

Actually I want that when 1 meter covered by the device a toast notification appears and it shows One meter has been covered.Similarly when again one meter will be cover the toast notification again appears.This phenomena continues further.Please help me to sort out the problem.Please provide me a sample code to do that...Thanks in Advance!!!
There is no location technology with one-meter resolution available to Android devices. Hence, what you want is not possible, sorry.

I want to detect montion by accelerometer.I found on internet how to init sensor and how to read values. I read values with:
Sensors.readSensor(Sensors.SENSOR_ACCELEROMETER, out);
But how can I use this values to detect montion.How can I detect LIFT UP,LIFT DOWN,MOVE RIGHT,MOVE LEFT,MOVE FORWARD,MOVE BACK,ROTATE LEFT,ROTATE RIGHT,SHAKE and other.
Whenever the the position is changed, use
onSensorChanged(SensorEvent event)
using the event object you can fetch the changed values, and based on that you can decide you motion. Best example for motion detection can be found in the below link:
How can I get the direction of movement using an accelerometer?

I want to know if the gps is active and able to report fixes. (basically the gps icon is solid and not blinking). I checked other answers on SO but I was wondering why this answer wouldve work (or would it). Basically every second I request location and if the timestamp of the current location is equal to the last one then there is no fix. Otherwise the timestamp will keep increasing right?
Comments?
The right way to do it is to request gps status updates, and implement the onStatusChanged function. The status GPS_EVENT_FIRST_FIX will be passed as soon as you have enough sattelites to calculate the location.
