Android App crash when come back from long idle

Question

I'm some what new to Android. My application crash when user return from long idle. I have read the Android app life cycle and debug the app. It looks like my app crash at the onCreate method when user come back from long idle. Below is my onCreate code. It get Global Variable (CustomerName) which is set from previous activity. Then, pull data from SQLLite base on the CustomerName to display data. I think the Android VM has killed the process when user return to the activity, but I thought the process should work when the onCreate is call again. Any help would be greatly appreciated.

protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    this.requestWindowFeature(Window.FEATURE_NO_TITLE);
    setContentView(R.layout.activity_report_review);
    intialize();
    adddynamiccheckboexes();

    //Initialize
    metrics = new DisplayMetrics();
    getWindowManager().getDefaultDisplay().getMetrics(metrics);
    panelWidth = (int) ((metrics.widthPixels)*0.75);

    headerPanel = (RelativeLayout) findViewById(R.id.header);
    headerPanelParameters = (LinearLayout.LayoutParams) headerPanel.getLayoutParams();
    headerPanelParameters.width = metrics.widthPixels;
    headerPanel.setLayoutParams(headerPanelParameters);

    menuPanel = (RelativeLayout) findViewById(R.id.menuPanel);
    menuPanelParameters = (FrameLayout.LayoutParams) menuPanel.getLayoutParams();
    menuPanelParameters.width = panelWidth;
    menuPanel.setLayoutParams(menuPanelParameters);

    slidingPanel = (LinearLayout) findViewById(R.id.slidingPanel);
    slidingPanelParameters = (FrameLayout.LayoutParams) slidingPanel.getLayoutParams();
    slidingPanelParameters.width = metrics.widthPixels;
    slidingPanel.setLayoutParams(slidingPanelParameters);

    CustomerName = ((GlobalVariables) this.getApplication()).getSomeVariable();
    //Check to see if CustName exist.  If not, go to Main screen
    CustomerName.trim();
    if (CustomerName.equals("null") || CustomerName.equals("")){
