Well, then you would need some code to get the actual pixel dimensions of the screen... right now you have hardcoded values of 750.  Keep in mind that doing this will cause distortion of the image... It will look stretched either in width or height.

What exactly are you trying to accomplish?  You said "the returned image is stretched and doesn't fit the mobile screen size" but I don't see anywhere in your code where you are doing anything with the screen size of the device...  What exactly are you expecting and what exactly are you seeing?

 Code:
 I have this code in the Activity result, when the user hits load, it will open the gallery allow him to choose a picture. The selected pictured is passed to another activity, here is where i'm facing the problem. The picture doesn't fit the screen.
     
                        
                Uri selectedimage= data.getData();

         Uri contentUri = data.getData();          

             String[] proj = { MediaStore.Images.Media.DATA };         

             Cursor cursor = managedQuery(contentUri, proj, null, null, null);         

             int column_index = cursor.getColumnIndexOrThrow(MediaStore.Images.Media.DATA);         

             cursor.moveToFirst();         

             String tmppath = cursor.getString(column_index);

             

         Intent intent= new Intent(this,NasalProjectionActivity.class);

         intent.putExtra("imagePath",tmppath);

           startActivity(intent);  


 Receiving Activity,

 Thats what i have on the receiving activity.

    

     Bitmap b = BitmapFactory.decodeFile(getIntent().getStringExtra("imagePath"));

        int newHe=750;

        int newWe=750;

       


        int width=b.getWidth();

        int height = b.getHeight();

        float scaleWidth = ((float) newWe) / width;

        float scaleHeight = ((float) newHe) / height;

        Matrix matrix = new Matrix();

        matrix.postScale(scaleWidth, scaleHeight);

        Bitmap resizedBitmap = Bitmap.createBitmap(b, 0, 0, width, height, matrix, false);         


Thanks alot
