I have a RecyclerView that launches CollapsingToolbarLayout, and when I try to open the minimized toolbar again in 4.2.2, I get a crash below. Any ideas?
java.lang.IllegalArgumentException: width and height must be > 0

Update:
It looks like the method in the library that causes the crash checks to see if the height or width is greater than 0, but the bitmap requires both values to be> 0:
private void ensureExpandedTexture() {
if(this.mExpandedTitleTexture == null && !this.mExpandedBounds.isEmpty() && !TextUtils.isEmpty(this.mTextToDraw)) {
this.mTextPaint.setTextSize(this.mExpandedTextSize);
this.mTextPaint.setColor(this.mExpandedTextColor);
int w = Math.round(this.mTextPaint.measureText(this.mTextToDraw, 0, this.mTextToDraw.length()));
int h = Math.round(this.mTextPaint.descent() - this.mTextPaint.ascent());
this.mTextWidth = (float)w;
if(w > 0 || h > 0) {
this.mExpandedTitleTexture = Bitmap.createBitmap(w, h, Config.ARGB_8888);
Canvas c = new Canvas(this.mExpandedTitleTexture);
c.drawText(this.mTextToDraw, 0, this.mTextToDraw.length(), 0.0F, (float)h - this.mTextPaint.descent(), this.mTextPaint);
if(this.mTexturePaint == null) {
this.mTexturePaint = new Paint();
this.mTexturePaint.setAntiAlias(true);
this.mTexturePaint.setFilterBitmap(true);
}
}
}
}

I filed an error: Crash in Design support library - CollapsingTextHelper class - but if anyone has a fix, in the meantime I will be very grateful!
