Crazy amounts of crashes .updateBitmap IllegalArgumentException

[easycheese]

I just integrated Showcaseview again after a two year hiatus and am regretting it...

It works fine on my test devices but numerous users are getting crashes and the stacktrace is from the library at:

Fatal Exception: java.lang.IllegalArgumentException width and height must be > 0 com.github.amlcurran.showcaseview.ShowcaseView.updateBitmap (ShowcaseView.java:211) com.github.amlcurran.showcaseview.ShowcaseView.access$100 (ShowcaseView.java:51) com.github.amlcurran.showcaseview.ShowcaseView$1.run (ShowcaseView.java:187)

ShowcaseView is being run 5 seconds after launch (so the view is definitely created) and I'm targeting a point, not a specific view (just in case).

I searched the web and found a few things here and there, most of the responses were not helpful. Currently the only solution I have is calling the showcase a single time (therefore it will always work on the second launch).

        new Handler().postDelayed(new Runnable() {
            @Override
            public void run() {

                new ShowcaseView.Builder(MainActivity.this)
                        .setTarget(new PointTarget(250, 350))
                        .setContentTitle(getString(R.string.showcase_title))
                        .setContentText(getString(R.string.showcase_description))
                        .singleShot(125)
                        .setStyle(R.style.CustomShowcaseTheme)
                        .build();

            }
        }, 5000);
    }

Agree, got the same issue

[vicpinm]

exact same error here

[easycheese]

I figured out the problem. I was launching a tutorial first and this would trigger at the same time. Because the tutorial was visible first, this would cause a crash. Explicitly calling it AFTER the tutorial will prevent the crash.

got the same issue

just had the same issue in my app.

I've targeted a textview in the first row of a recyclerView via the onBindViewHolder (just to see if it would work)

@Override
        public void onBindViewHolder(ViewHolder viewHolder, int i) {

        [...]

            if(i == 0){
                Log.d(TAG,"showHelp from onBindViewHolder");
                showHelp(viewHolder.tv_verify_list_billed);
            }

  private void showHelp(View view){

        if(view == null){
            Log.d(TAG,"showHelp view was null");
            return;
        }

        ViewTarget vt = new ViewTarget(view);

        new ShowcaseView.Builder(getActivity())
                .setTarget(vt)
                .setContentTitle(getString(R.string.list_title))
                .setContentText(getString(R.string.list_content))
                .setStyle(R.style.CustomShowcaseTheme)
                .hideOnTouchOutside()
                .replaceEndButton(R.layout.showcase_button)
                //.singleShot(ShowcaseView_SSIDs.InventoryList.hashCode())
                .build();
    }

it works perfectly on first load of the recyclerView list, but when i swipeRefresh the recyclerView i get the error.

Hopefully this helps to reproduce it for bug fixing.

[amlcurran]

Interesting, thanks for the reproduction steps. I'd imagine that this isn't exactly how best to use showcaseview with a RecyclerView but will take a look and report back!

[amlcurran]

@easycheese can you tell me what devices are having the issue?

[easycheese]

@amlcurran as far as I can tell it will happen on any device

[Fornori]

I have the same issue

[Fornori]

Any idea to fix this?

[amlcurran]

@Fornori Can you give me more details of what you're? I have no way of reproducing this right now because I'm not sure what is happening. Any code that reproduces the crash will be great

[Fornori]

Sorry, but code was gone. I replaced it by another. And now can't reproduce. If the app will crash again. I will write full description.

[cazador4]

Same problem here

I believe this is a duplicate of https://github.com/amlcurran/ShowcaseView/issues/197, which should be fixed in com.github.amlcurran.showcaseview:library:5.4.3.
