Accessing camera using ACTION_IMAGE_CAPTURE

Question

What i am trying to do is create a new folder and save the image captured by camera in that folder.I am trying to achieve it using following snipet:

public class DocsAdd extends Activity
{   
    private static int TAKE_PICTURE = 1;
    private Uri outputFileUri;
    Bitmap thumbnail;
    @Override
    public void onCreate(Bundle savedInstanceState) 
    {
        super.onCreate(savedInstanceState);
        Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);        
        intent.putExtra(MediaStore.EXTRA_OUTPUT, outputFileUri);
        File filename;
        try 
        {
            long currentTime = System.currentTimeMillis();
            String fileName = "img" + currentTime+".jpg";
            String path = Environment.getExternalStorageDirectory().toString();             
            filename = new File(path + "/AutoistDiary/"+ fileName);
            FileOutputStream out = new FileOutputStream(filename);            
            out.flush();
            out.close();     
            MediaStore.Images.Media.insertImage(getContentResolver(),filename.getAbsolutePath(), filename.getName(), filename.getName());

          outputFileUri = Uri.fromFile(filename);
        } 
        catch (Exception e) 
        {
            e.printStackTrace();
        }
        intent.putExtra(MediaStore.EXTRA_OUTPUT, outputFileUri);
        startActivityForResult(intent, TAKE_PICTURE);
    }
    @Override
    protected void onActivityResult(int requestCode, int resultCode, Intent data) 
    {
        if (requestCode == TAKE_PICTURE)
        {
            Uri imageUri = null;            
            if (data!=null) 
            {
                if (data.hasExtra("data")) 
                {
                    thumbnail = data.getParcelableExtra("data");
                    Intent docsShow_intent=new Intent(this,DocsShow.class);
                    startActivity(docsShow_intent);
                }
            } 
            else 
            {
            }

        }  
    }
}

but when i run it on Optimus1 it is not returning any result to my activity, came across a link Camera on Android Example which states the same problem that i am facing currently so can help me with this. ?

Unfortunately there is a bug on some devices causing the Intend data parameter in onActivityResult to be null when you use the MediaStore.EXTRA_OUTPUT flag in your intent for the camera. A workaround is to keep the outputFileUri variable global so that you can access it again in your onActivityResult method. Something like this:

Uri outputFileUri; //global variable

Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
File photo= new File(Environment.getExternalStorageDirectory(), "Autoist Diary"); 

if (! photo.exists())  
{  
    photo.mkdirs();  
    if (! photo.mkdirs())  
    {  
        Log.i("MyCameraApp", "failed to create directory");  
    }  
}  
puc_img=new File(photo,"Puc_Img.jpg");  
outputFileUri = Uri.fromFile(photo);  
intent.putExtra(MediaStore.EXTRA_OUTPUT,outputFileUri);  
StartActivityForResult(intent, TAKE_PICTURE);  

public void onActivityResult(int requestCode, int resultCode, Intent data)  
{  
    super.onActivityResult(requestCode, resultCode, data);  
    switch (requestCode)   
    {  
       case TAKE_PICTURE:  
           if (resultCode == Activity.RESULT_OK)   
           {                   
               if(data != null) { //if the intent data is not null, use it
                  puc_image = getImagePath(Uri.parse(data.toURI())); //update the image path accordingly
                  StoreImage(this,Uri.parse(data.toURI()),puc_img);
               }
               else { //Use the outputFileUri global variable
                  StoreImage(this,outputFileUri,puc_img);
               }
           }   
       break;
    }  
}  
public static void StoreImage(Context mContext, Uri imageLoc, File imageDir)  
{  
    Bitmap bm = null;  
    try   
    {  
        bm = Media.getBitmap(mContext.getContentResolver(), imageLoc);  
        FileOutputStream out = new FileOutputStream(imageDir);  
        bm.compress(Bitmap.CompressFormat.JPEG, 100, out);  
        bm.recycle();  
    }  
    catch (FileNotFoundException e)   
    {  
        e.printStackTrace();  
    }  
    catch (IOException e)   
    {  
       e.printStackTrace();  
    }  
    catch (Exception e)   
    {  
        e.printStackTrace();  
    }  
}
public String getImagePath(Uri uri) {
    String selectedImagePath;
    // 1:MEDIA GALLERY --- query from MediaStore.Images.Media.DATA
    String[] projection = { MediaStore.Images.Media.DATA };
    Cursor cursor = managedQuery(uri, projection, null, null, null);
    if (cursor != null) {
        int column_index = cursor
                .getColumnIndexOrThrow(MediaStore.Images.Media.DATA);
        cursor.moveToFirst();
        selectedImagePath = cursor.getString(column_index);
    } else {
        selectedImagePath = null;
    }

    if (selectedImagePath == null) {
        // 2:OI FILE Manager --- call method: uri.getPath()
        selectedImagePath = uri.getPath();
    }
    return selectedImagePath;
}

This workaroud has worked for me. Hope that helps.
