How to handle try-catch clause for imageView.setImageURI(Uri.parse(local_path));

Question

I want to handle the case when an imageView tries to open an image from local files that was previously deleted by the user and display a default image instead. For this I try:

int flag = 0;
try{
        img_car.setImageURI(Uri.parse(path_picture));
        flag = 1;
    }
catch(Exception e){ //if I put FileNotFoundException I get error: Unreachable catch block for FileNotFoundException. This exception is never thrown from the try 
// statement body
        Log.i("TAG EXCEPTION PIC", e.getMessage());
        img_car.setImageResource(pictureId);
    }

Both img_car.setImageResource(pictureId); and img_car.setImageURI(Uri.parse(path_picture));(when the picture physically exists) work.

My problem is that I can't catch the exception (when the picture does not exists), basically this clause does not throw it.(My LogCat does not display any info log message). Even that, LogCat displays java.io.FileNotFoundException:

 09-06 13:12:22.066: W/ImageView(27274): Unable to open content:
 file:///storage/sdcard0/folder_name/my_image.PNG

 com.myapp....

pointing me to the line: img_car.setImageURI . Another strange thing is that the flag has the value 1 after the try-catch is executed even the exception occours on the line above so theoretical this line shouldn't be executed.(right?). Any help will be highly appreciated. Thank you!

I quit using try-catch and instead did this:

 Bitmap bitmap = BitmapFactory.decodeFile(path_picture);
            if(bitmap != null)
                imgdata.setImageBitmap(bitmap);
            else{
                imgdata.setImageDrawable(getResources().getDrawable(R.drawable.default_image));
            }

I extract first the content into a bitmap and if bitmap is null then load default image. It works.
