I had some trouble with the material version of the DDL form not loading on my phone. It worked fine when I ran it on the emulator though. I couldn't get the filepicker to work on my phone or on the emulator but everything else went really smoothly

Hey Krista! Congratulations, we'll contact you separately to arrange your gift shipment.

As far as the file picker on the phone - can you say what Android version you are using? And if possible, can you look at the adb logcat output and see if there are obvious screens-related errors? Thanks!

I'm running Android 4.4.2 on my phone.

Here's the error log when the DDL form won't load on my phone:

[Javier Gamarra, modificado hace 8 años.]

Thank you! (and sorry :S)

I'll check and send a hotfix asap!

[Javier Gamarra, modificado hace 8 años.]

Hi!,

I've released a hotfix (1.1.2) to master in github fixing the material DDL form problem. It'll be available in maven central / jcenter in some days, we want to release another bugfixes with this one.

The material and DDL problem was caused by an inexistent type in the edittext of a layout file (only in the material viewset and failing only in some phones).

I could't reproduce the file chooser bug... I've tried with 3 phones and 6 (3 genymotion, 3 emulator) images, without success. But I think I can imagine some reasons for the NPE, it could be due to permissions... the file chooser reads the primary storage and could need permissions to do it in some phones, the dev guide/docs advise that you need write permissions to be able to use the document field (for the camera, and read for the chooser). Did you add a WRITE permission?

Or it could be due to the SD/primary storage being unavailable for some reason (like being used by the system or mounted in the PC).

I've added checks for these cases and I hope that those will fix (or at least reveal) the underlying problem.

I'll let you know when the hotfix is available in mavencentral/jcenter.

Thanks for the feedback!

Liferay Screens - Android - Custom Screenlet

1. I could setup Liferay Screens and Setup Up the Demo Apps and its work perfectly fine.
2. I also created a Custom Screenlet for Android.

Attached the Screen Shots for Reference. [Emulator used is BlueStacks]

1. Custom Screen Let - MessageBoard
2. Listing of the Messages after Adding the Message Board
3. Green Theme Liferay Test App

[Juan Fernández, modificado hace 8 años.]

Wow, Jitesh! This is so cool! Great job, man!
I have a quick question for you: would you be open to contributing this Message Boards Screenlet to the project?
As you know, Liferay Screens is an open source project, and I am pretty sure this contribution would be extremely welcomed by our community.
Please let me know what do you think about this: it would be a great opportunity to contribute to the Screens project...and be remembered forever! ;)
Best,
Juan

[Jitesh Dadlani, modificado hace 8 años.]

Thanks Juan, I am open for contributing to Liferay

[Juan Fernández, modificado hace 8 años.]

Awesome! Next step would be to send a pull request to our repo: github.com/liferay/liferay-screens
Looking forward to see this new Screenlet in the next Screens major version!
Thanks for your generosity,
Juan
