image put into ImageView from taken picture not always showing up

Question

An image taken from the camera doesn't always show up in my ImageView. It seems like it is random when it wants to show up. Why is it doing this?

Activity that takes picture

private void takePicture() {
    Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
    if (intent.resolveActivity(getPackageManager()) != null) {
        startActivityForResult(intent, REQUEST_PICTURE);
    }
}

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);
    String spokenText;

    // Handles picture taking after finished
    if (requestCode == REQUEST_PICTURE && resultCode == RESULT_OK) {
        Bundle extras = data.getExtras();
        Bitmap image = (Bitmap) extras.get("data");

        ImageView imageResult = (ImageView) findViewById(R.id.result_image);
        imageResult.setImageBitmap(image);

        ImageHandler imageHandler = new ImageHandler(this);
        imageHandler.writeToFile(image, step.getChecklistId(), step.getOrder());

        step.setImageFilename(imageHandler.getFilename(step.getChecklistId(), step.getOrder()));
        finishStep();
    }
}

XML to show picture

<ImageView 
            android:id="@+id/result_image"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_gravity="center"
            android:scaleType="fitCenter"
            android:adjustViewBounds="true"
            android:contentDescription="@string/taken_img_desc" />

intent extra data return for you the URi (place where the camera put the image)that you can assign it for the imageview directly — mohammed momn, Jan 21 '14 at 00:29

Are you using notifyDataSetChanged for your adapter? Is your view being refreshed? Try .invalidate();

Just need to `.invalidate()`. Thank you! – The Nomad Jan 21 '14 at 22:14
I have this same problem. where do I get invalidate before or after setting the image? I tried both but still get the random result. – learner Feb 11 '14 at 23:33

One more thing: You might experience that the camera intent does not return an image or an uri to an image. I created a wrapper to help you with that. See the whole discussion on stackoverflow here or find the code on github.
