Why is the view responsible to instantiate the P in MVP ?

Posted: 07 Sep 2016 11:08 PM PDT

In MVP the View is supposed to be passive, the data being collected, formated and passed back by the Presenter. Why is the View responsible to instantiate the P in Android approaches ? Is it just by ease, because the Framework does not permit to instantiate Views directly ? Does MVP imply to have the P created by the View ?

I would say the P should have the responsibility to instantiate the View, it is the Controller and the view is supposed to be passive.

Reference : http://martinfowler.com/eaaDev/ModelViewPresenter.html seems to go in that direction

Reference : http://www.infragistics.com/community/blogs/todd_snyder/archive/2007/10/17/mvc-or-mvp-pattern-whats-the-difference.aspx seems to say that it would me more the front controller in MVC approaches.

Do you have any other references (the real true definition of MVP and the explanation) or an opinion on the subject ?

Thanks

Has anyone ported their apps' notifications from GCM to FCM? I have some questions.

Posted: 07 Sep 2016 07:05 AM PDT

Hi,

We are on the verge of being forced to update to FCM(Firebase's upgrade over google cloud messenging), because on iOS, firebase pods and Gcm Pods can't coexist (As long as I am not missing anything). After reading guides, I still have some questions unanswered, which are.

  • After we introduce FCM in next version, what will happen to GCM notifications on older versions? Are they abandoned? Or there is some automatic backporting in Client sides and server sides?

  • Will sending requests to fcm.googleapis.com/fcm/be redirected to gcm-http.googleapis.com/gcm/ if the token, topic etc created using GCM?

  • Are there other problems/issues regarding to migration which were not mentioned?

Though I am curious to know general experience (regardless of platforms), I can understand if this discussion becomes limited to Android Only.

android-cmake-installer : A script to install CMake for Android builds on CI servers

Posted: 07 Sep 2016 10:02 AM PDT

tl;dr, I wrote a script

Hey there people,

I was recently experimenting with using the new CMake support on an Android project that uses C++. I realized that Google provides no way that I could see for installing CMake via the SDK Manager, which means that you cannot use the traditional methods on CI servers such as Travis.

So, I created a script https://github.com/Commit451/android-cmake-installer which will pull CMake from Google's servers and install it. It's a fairly simple .sh script which I tested on Mac and Linux and seems to work on Travis CI. I am currently using it in PixelAdjuster and it works well.

Hope this saves someone else some time!

To everyone here, huge thanks. My team just completed and submitted our final project for CodePath's Remote Bootcamp and I wouldn't have even learned about this if it weren't for this sub

Posted: 07 Sep 2016 07:26 AM PDT

A couple of months ago, I was learning Android (from an iOS background) and I posted here looking for resources aside from Big Nerd Ranch.
I was referred to CodePath by /u/WingnutWilson and I noticed they had an 8-week program.
I applied and was emailed the application project description (basically a Todo App but to be built using a variety of features that would make it a better experience on Android).
After finishing it, I was interviewed by Nathan and I was asked to spend a little time cleaning up the UI to make it look less "engineered".
I got accepted and it has been a roller coaster but I'm incredibly glad and thankful I did it.
Thanks a lot guys!
