I have a project created in robohelp11.
My project has about 20 topics. I am able to generate the project without issues in Responsive HTML5, and I can view the project in Chrome and Internet Explorer without issue.
The Help content is being added to an existing android app and displayed in the devices browser, called from the app.
Issue: Help opens on the android device, but the topics are not being displayed, the window is blank. I am able to open and view without issue the TOC, index, and glossary.
Side note: I generated the project as a native android app and installed it on my phone, everything worked fine, no issues at all.
Perhaps consider downloading and testing your output using RoboHelp 2015 Release?
Same result when generated by Robohelp 2015.
And one more thing to consider. In RoboHelp 2015 Release, did you also download and install the latest service release? (From RoboHelp, click File > Help > Updates.
It could be that a service release corrects this issue.
You might also consider reporting it to Adobe using the link below
Looks like the iframe in the HTML output was causing the issue. The Android developer had to make some settings changes.
Any chance of sharing what they changed please? What was the issue?
