map overlay sits in Map_form which extends mapactivity. I tried to
pass in the sensor value to overlay at the method below:
private final SensorListener mListener = new SensorListener()
{
public void onSensorChanged(int sensor, float[] values)
{
if (Config.LOGD) {
Log.d("", "sensorChanged (" + values[0] + ", " +
values[1] + ", " + values[2] + ")");
}
overlay.setValue(values[0]);
}
public void onAccuracyChanged(int sensor, int accuracy){}
};
But it crushes.
Below is my code for Map_Form:
