problems with eclipse
Closed this issue · 9 comments
Hi,
newbie question here: I loaded the project in eclipse, connected my samsung phone and hit the run button: I get three error messages:
- the project was not built since its build path is incomplete. Cannot find the class file for java.lang.Object
2)The type java.lang.Object cannot be resolved. It is indirectly referenced from required .class files - Unable to resolve target 'android-8'
...any advice will be really appreciated.
Thanks
You'll want to learn a bit more about Eclipse - sounds like you haven't
specified a Java Runtime for Eclipse which is why it can't compile.
StackOverflow will be your friend: http://www.stackoverflow.com. You can
also Google your error messages to find fixes.
Unfortunately I don't have time to walk you through the fundamentals but
luckily this stuff is documented all over the web. However, if you
encounter a Friar specific problem I can definitely help.
Best of luck, don't be discouraged, it will take a little effort at first
but once you get started it'll become easier and easier (and hopefully more
fun as well)! Happy hacking!

hanchang,
I've made it!
I'm not an eclipse guy, (it's not my business) but after some experiment, I can see the book on my cell phone.
For this demo I used the Laker Compendium, only to test funcionality for the Android platform.
The swipe between pages works, but it seems all the javascript behavior is lost: no image galleries, no audio, and even double tapping for the menu doesn't work.
I used the same book folder (with all img, html, js, etc...) that worked with baker on my iPad...
Unfortunately, I don't own an android tablet, and I'm only able to test on my smartphone.
Off topic: from the home page "http://www.friarframework.com", when you click on "tutorials" you are redirected to baker site, instead of "http://www.friarframework.com/tutorials/" (which I've found after googling for help...)
bye!
Glad to hear it Marco!
The reason the JavaScript behavior is missing is because Android's WebView
disables JavaScript by default. You can Google how to enable JavaScript for
Android WebViews; after making the change everything should just work.
That's a good point though, I should probably document that somewhere... I
made the poor assumption that anybody using Friar would be a seasoned
Android developer.
Thanks for the heads up about the link - the reason the "Tutorial" link
points to the Baker website is that the book creation process is identical
and they've done a great job on explaining how to package up your book into
the HPub format which is exactly what Friar uses. In fact, the Baker guys
wanted to make sure that Friar used HPub as well which is awesome, this way
any user who prepared a book for Baker can just drop it into Friar and vice
versa.
Hope that makes sense and congrats on your technical persistence!

Hey Han!
just found the line of code for enabling js (if you're not familiar with eclipse/android, please open FriarBook.java inside the "src" folder. You should find "webView.getSettings().setJavaScriptEnabled(false);" - just set it to "true.").
Well, the app now loads js, but some strange things happen:
- if you are on page 1 (I'm refferring to the sample "Laker Compendium") there's an image gallery. When you swipe between images, the event is overwritten by the standard page turn event. As a result, you're redirected to the next page.
- on page 2 the button for playing music doesn't work.
- double tapping for the index page just doesn't work.
What should I do? Are there others "obscure" settings in eclipse?
I love Baker and I think your effort in "translating" the code for Android is a great work.
But if you're not an android dev, well, it's not that easy...
When I think about a digital publication the first thing for me is interactivity: audio, video, js libraries, and so on...nobody wants to see static layouts (there's print for that...). With Baker all of this is possible. The question is: can Friar do the same?
If yes, could you explain how?
Thanks again!
Marco
Hi Marco, sorry it took awhile to respond, got a bit busy recently but now
have some free time to look into this issue.
The issue with the Laker Compendium in Friar Framework is that it uses a
custom client side include library:
http://www.massimocorner.com/libraries/csi/
However, Android doesn't seem to support any client side includes:
http://stackoverflow.com/questions/9003402/jquery-and-phonegap-include-a-html-file-clientside-with-html-or-js
This is not a standard way of making web pages so I am not surprised it
does not work in Android's WebView due to its strict security settings. See
point number three in the list below, this is the method that the CSI
library in Laker Compendium tries to use, and which Android rejects.
http://en.wikipedia.org/wiki/Server_Side_Includes#Client_Side_Includes
The standardized method to accomplish the same thing would be through
something like an iframe, which is the first option listed in the link
above. If you really need to get Laker working, I can recommend that you
refactor the code from using the CSI library into using iframes.
Otherwise, you can just develop your own HTML5 book without using Laker as
a starting point.
Hope that helps!

Han,
thank you very much for your reply.
I wasn't aware of the issue about clients include, so I really appreciate your help.
If there's a quick fix for the (lost) js functionality (besides the "FriarBook.java" setting mentioned above), please let me know.
bye!
hi ,
i have the same problem on the slideshow script. in my case it works on the simulator (4..0.3) slideshow works fine and does not swipe to the next page. however when i create the apk package and load it to Samsung Galaxy (2.3) it does not work as expected.
also it works on the simulator ver2.3 device
Hi bahmet,
sorry, but I wasn't able to solve the issue. Maybe some eclipse/friar expert could help us?
bye
