Camera Functionality Not displaying Image

I have a hybrid application, which opens native camera of android. My code : 

public class CameraFunActivity extends Activity {  
    OpenCamera openCamera;  

   /** Called when the activity is first created. */
   @Override
    public void onCreate(Bundle savedInstanceState) {  
       super.onCreate(savedInstanceState);    
       setContentView(R.layout.main);    
     WebView webView=(WebView)findView  ById(R.id.webkitWebView1);  
     WebSettings settings = webView.getSettings();  
     settings.setJavaScriptEnabled(true);  
     settings.setDatabaseEnabled(true); 
      openCamera=new OpenCamera(webView,CameraFunActivity.this);  
         webView.addJavascriptInterface(openCamera,"camera");

    }  
   @Override   
     protected void onActivityResult(int requestCode, int resultCode, Intent data) {

     if (requestCode== 0 && resultCode == Activity.RESULT_OK){ 
         System.out.println("!!!!!!!!!!!!!!!!!!!!Camera Working...........");
         String imagePath =  "file:/"+openCamera.getPath();
        System.out.println("Image Pathhhhhhhhhh :::::::::::: " + imagePath);
        openCamera.setPath(imagePath);

.. }

HTML: function captureImage1(){ camera.startCamera(); var path="file://" + camera.getPath(); //alert(path); document.getElementById("image1").src=path; }

public OpenCamera (WebView appView,Activity context) {
this.mAppView = appView;
this.context=context; } 

public void setPath(String path){

    _path=path;
}
public String getPath(){

    return _path;
}
public void setBitmap(Bitmap bitmap){
    System.out.println("setting bitmap");
    this.bitmap=bitmap;
}
public Bitmap getBitmap(){
    System.out.println("getting bitmap");
    return bitmap;
}

public void startCamera(){
    /*
    Camera camera = Camera.open();
    Camera.Parameters parameters = camera.getParameters();
    parameters.setPictureFormat(PixelFormat.JPEG);
    camera.setParameters(parameters);*/

    Date dt = new Date();   
    int date=dt.getDate();
    int hours = dt.getHours();   
    int minutes = dt.getMinutes(); 
    int seconds = dt.getSeconds();   
    String curTime = date+"_"+hours + "_"+minutes + "_"+ seconds;
    _path=Environment.getExternalStorageDirectory() +"/"+curTime+".jpg";
    File file = new File( _path );
    Uri outputFileUri = Uri.fromFile( file );
    Intent intent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE );
    intent.putExtra( MediaStore.EXTRA_OUTPUT, outputFileUri );





//  System.out.println("Paramssssssssssssss  " + camera.getParameters().toString());

    context.startActivityForResult(intent,0);

Sometimes it dispalays the image at img tag src, sometimes it doesn't. Need help to find out the problem.

Also, is it something related to Orientation change??

Thanks

I resolved it in this way :

add :
function openCamera1(){
result = camera.startCameraActivity1();
path1=camera.getImagePath1();
path="file://"+path1; do{
fileIndicator=camera.findEOF();
}while(!fileIndicator)
document.getElementById("image1").src=path;
}

And in OpenCamera add a method: 

public boolean findEOF(){  
       File file=new File(imagePath1);  
       System.out.println("Inisde EOFL::::::::::::::"+file.length());  

        if(file.length()>0){ 
           System.out.println("Inisde length is::::::::::::::"+file.length());  
            return true;
      }         
       return false;

   }

So the problem was get imagePath() was being called before the image is written to the file
