            toast.show();
        }
    }    

}

EDIT: (added as following where data.getData() is null always)

final int CAPTURE_IMAGE_ACTIVITY_REQUEST_CODE = 100;
final int CAPTURE_VIDEO_ACTIVITY_REQUEST_CODE = 200;

public void onClick(View v) {
        if (v.getId() == R.id.capture_btn) {     
            try {
                Intent captureIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
                //startActivityForResult(captureIntent, CAMERA_CAPTURE);
                startActivityForResult(captureIntent, CAPTURE_IMAGE_ACTIVITY_REQUEST_CODE);
            }
            catch(ActivityNotFoundException anfe){
                String errorMessage = "Whoops - your device doesn't support capturing images!";
                Toast toast = Toast.makeText(this, errorMessage, Toast.LENGTH_SHORT);
                toast.show();
            }
        }
}

    @Override
    protected void onActivityResult(int requestCode, int resultCode, Intent data) {
        if (requestCode == CAPTURE_IMAGE_ACTIVITY_REQUEST_CODE) {
            if (resultCode == RESULT_OK) {
                // Image captured and saved to fileUri specified in the Intent
                Toast.makeText(this, "Image saved to:\n" +
                         data.getData(), Toast.LENGTH_LONG).show();
            } else if (resultCode == RESULT_CANCELED) {
                // User cancelled the image capture
            } else {
                // Image capture failed, advise user
            }
        }

        if (requestCode == CAPTURE_VIDEO_ACTIVITY_REQUEST_CODE) {
            if (resultCode == RESULT_OK) {
                // Video captured and saved to fileUri specified in the Intent
                Toast.makeText(this, "Video saved to:\n" +
                         data.getData(), Toast.LENGTH_LONG).show();
            } else if (resultCode == RESULT_CANCELED) {
                // User cancelled the video capture
            } else {
                // Video capture failed, advise user
            }
        }
    } 

EDIT 2:

protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    //super.onActivityResult(requestCode, resultCode, data);
    if (resultCode == Activity.RESULT_OK) {
        if(requestCode == CAMERA_CAPTURE){
            picUri = data.getData();
            performCrop();
        }
        else if(requestCode == PIC_CROP){
            Bundle extras = data.getExtras();
            Bitmap thePic = extras.getParcelable("data");
            ImageView picView = (ImageView)findViewById(R.id.picture);
            picView.setImageBitmap(thePic);
        }
    } else {
        String errorMessage = "Whoops - resultCode return: " + resultCode  +" requestCode: " + requestCode;
        Toast toast = Toast.makeText(this, errorMessage, Toast.LENGTH_SHORT);
        toast.show(); 
        Bundle extras = data.getExtras();
        Bitmap thePic = extras.getParcelable("data");
        ImageView picView = (ImageView)findViewById(R.id.picture);
        picView.setImageBitmap(thePic);         
    }
} 

Answer 1

If resultCode is 0 then it means your invoked activity was cancelled. Either they must have pressed back button, orso to come back to this activity. Changes are your implementation is wrong.
