facebook - image from camera intent issue in android

I am integrating facebook with android and I want when taking a phot , save it to sdcard and then upload it to facebook.

Here is my code:

photo_up=(Button)findViewById(R.id.camera_foto_button);
            photo_up.setOnClickListener(new View.OnClickListener() {
                   public void onClick(View v) {
                       final Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);  
                       intent.putExtra(MediaStore.EXTRA_OUTPUT, Uri.fromFile(getTempFile(PlaceScreen.this)) );   
                       startActivityForResult(intent,CAMERA_REQUEST); 
                   }
                });

 private File getTempFile(Context context){  
          //it will return /sdcard/image.tmp  
          final File path = new File( Environment.getExternalStorageDirectory(), context.getPackageName() );  
          if(!path.exists()){  
            path.mkdir();  
          }  
          return new File(path, "image.png");  
        } 

and the OnActivity Result

protected void onActivityResult(int requestCode, int resultCode, Intent data) {  
    switch(requestCode){
                case CAMERA_REQUEST:{
                    final File file = getTempFile(this);  
                    try {  
                      bmp = MediaStore.Images.Media.getBitmap(this.getContentResolver(), Uri.fromFile(file) );  
                      // do whatever you want with the bitmap (Resize, Rename, Add To Gallery, etc)  
                    } catch (FileNotFoundException e) {  
                      e.printStackTrace();  
                    } catch (IOException e) {  
                      e.printStackTrace();  
                    }  


                    ByteArrayOutputStream stream = new ByteArrayOutputStream();        
                    bmp.compress(Bitmap.CompressFormat.PNG, 100, stream);         
                    byteArray = stream.toByteArray(); // convert camera photo to byte array  
                    Bundle params = new Bundle();       
                    params.putByteArray("picture", byteArray);      
                    params.putString("message", "Have fun");       
                    Utility.mAsyncRunner.request("me/photos", params,
                            "POST", new PhotoUploadListener(), null);
                    break;
                }

So what happens is this: Camera opens, imagae captured and saved but I get a force close and it is not uploaded on fb.

I checked it on my phone,too. Logcat is here:

edit:

Ok my bmp where is null. Why is that? What ius wrong?

bmp = MediaStore.Images.Media.getBitmap(this.getContentResolver(), Uri.fromFile(file) );  
bmp.compress(Bitmap.CompressFormat.PNG, 100, stream); 

can anyone find out why my bmp is null while I can see the image in the gallery. That means that image is taken normally but nothing gets as a result of bmp=MediaStore.Images.Media

While using the generic code available on net to call camera and take photo and retrive it, I faced some problem in SAMSUNG device at that time the same error occured Failure delivering result ResultInfo and couldn't find any solution may be its because of any API Level or Device dependancy.

But to overcome it I wrote my code another way to do the task, The code is here:

1) To Call Camera

        String _path = Environment.getExternalStorageDirectory()
        + File.separator + "TakenFromCamera.png";
        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);
        startActivityForResult(intent, 1212);

2) In ActivityResult to get Bitmap

            if (requestCode == 1212) {
                String _path = Environment.getExternalStorageDirectory()
                + File.separator + "TakenFromCamera.png";
                mBitmap = BitmapFactory.decodeFile(_path);
                if (mBitmap == null) {
                    // bitmap still null
                } else {
                    // set bitmap in imageview
                }
            }
