Using GPS Value in View

I'm having an issue taking a max speed value (recorded via GPS) from my application and using that value for my analog gauge view output. When running I receive a FC "unable to expand the view". I can enter a static value without any issue. I am attempting to pull the max speed value (mHighestSpeedNumber) from another view (GraphCanvas.java) used for a graph which works fine. In (Analogspeed.java) where I would like to place the value, I import my variable and place the following code which no syntax errors:

private float speedvalue = (float) Double.parseDouble(mHighestSpeedNumber.toString());
private float handTarget = speedvalue;

Upon doing this I then get the force close when calling the activity.

Any help would be appreciated. I have tried many scenarios and searched with no solution yet.

I believe part of the issue may be converting a double value to a float which it needs to be. Please let me know if any other information is needed.

Thanks

GraphCanvas.java

mHighestSpeedNumber = mUnits.conversionFromMetersPerSecond( calc.getMaxSpeed() );

Analogspeed.java

package com.datamonkey.android.test;

import java.text.DecimalFormat;
import java.text.NumberFormat;

import com.datamonkey.android.test.actions.utils.GraphCanvas;
import com.datamonkey.android.test.actions.utils.StatisticsCalulator;
import com.datamonkey.android.test.actions.Statistics;
import com.datamonkey.android.test.util.UnitsI18n;

import android.view.View;

public final class AnalogSpeed extends View {

private static final String TAG = AnalogSpeed.class.getSimpleName();

private GraphCanvas mHighestSpeedNumber;

// scale configuration
private static final int totalNicks = 65;
// number values for gauge
private static final float degreesPerNick = 270.0f / totalNicks;    
private static final int centerDegree = 0; // the one in the top center (12 o'clock)
private static final int minDegrees = 0;
private static final int maxDegrees = 200;

// hand d开发者_StackOverflow中文版ynamics -- all are angular expressed in F degrees
private boolean handInitialized = false;

// Starting Position of hand
private float handPosition = centerDegree;


private float speedvalue = (float) Double.parseDouble(mHighestSpeedNumber.toString());

private float handTarget = speedvalue;

You have a null pointer exception: what does line 135 look like?

EDIT: My expectation is that the mHighestSpeedNumber is null, which is where the failure is happening.
