    Fast track Udacity nanodegree

    Posted: 08 Aug 2018 12:17 PM PDT

    You can probably help me if you took the course, I'm talking about this one: https://www.udacity.com/course/android-developer-nanodegree-by-google--nd801

    So, all I need is a certificate because some of our clients think they're a good indicator of developer skill. What is the fastest way to get it?

    I read that it can be completed in two month (minimum requirement for courses), but I could not find a source of that info. Also what is the actual time required to code all projects required to pass it?

    Thinking about using Google Cloud to host mySQL databases, is that a good idea?

    Posted: 08 Aug 2018 06:26 AM PDT

    On their website, they say that they are cheaper, but what do you guys think?

    Also, do they have features such as BLOB variable types to store in their databases?

    Is this a correct implementation of MVP with multiple fragments?

    Posted: 08 Aug 2018 08:27 AM PDT

    I've been trying to implement MVP with multiple fragments and although I've seen some suggestions of using a single presenter for each fragment, I wanted to know if this implementation is correct as well.

    Imagine, for example, a registration screen with multiple steps or, on a tablet, with both fragments visible at the same time.

    UML chart:

    https://i.imgur.com/X4o4ogn.png

    Sorry for the mistakes, I'm still learning UML.

    An example sequence could look like this:

    1. Button is clicked by the user in Fragment 1.
    2. Fragment1.NotifyButtonClicked();
    3. MainActivity.onFragment1ButtonClicked();
    4. Presenter.performAction1();
    5. Model.ReturnStringFromDatabase(); // returns a stringFromDatabase
    6. MainActivity.updateText1And2(string);
    7. Fragment1.TextView.setText(string) AND Fragment2.TextView.setText(string)

    The idea is that the Presenter, which interacts with the model, APIs, etc... does not need to know how many fragments or view elements there are.

    Fragments are view elements and, as such, they are updated by the Activity just like one would update a TextView, a Button or any other element.

    Furthermore, with this implementation aesthetic changes are not passed to the presenter. They can simply be handled by the Activity with instructions returned back to the fragments. For example: "changing the color of a textview".

    Finally, this also allows easy coordination between fragments. The Activity could have a method like "updateTex1AndText2()" that simply makes changes to two different fragments at the same time.

    However, since I'm new to Android and software development as a whole, do you know if there are any obvious drawbacks to this solution?

    Thank you!

    Android 9 (Pie) problem renaming a DocumentFile

    Posted: 08 Aug 2018 05:10 AM PDT

    I tried my app on Android 9 on the emulator. It works fine but when calling renameTo() on a DocumentFile, it returns false, even though when I check, the file was renamed correctly and there is no problem. Can anyone else confirm this issue is a bug in Android 9? Thanks.

    So today I start the Android app developer path... And my Pc cant handle Android Studio's simulator

    Posted: 08 Aug 2018 03:42 AM PDT

    I don't have money for changing it today, its an old PC (fx 8320 - 8gb ram - 2gb vram - 1tb HDD). Android Studio's simulator isnt compatible with AMD CPUs and I feel I will need that feature. Any tip/recommendation?

    App getting too many uninstalls

    Posted: 08 Aug 2018 03:07 AM PDT

    I have an app on JS interviews on Play Store. In recent some days I see that the number of daily uninstalls has gone considerably high(around 80-90%). This uninstall rate was better before a month. Is this expected? How can I know the reasons for this?

    Hardware support for new RTT api?

    Posted: 08 Aug 2018 01:10 PM PDT

    I'm playing around with the new Wi-Fi location ranging with RTT. This is using my Pixel XL. The packageManager.hasSystemFeature(PackageManager.FEATURE_WIFI_RTT as well as WifiRttManager.isAvailable both return true, so I'm fairly confident the issue is not with my device.

    Of the handful of networks I'm scanning around me, all of them are giving me the status STATUS_RESPONDER_DOES_NOT_SUPPORT_IEEE80211MC

    I've spent the better part of the afternoon attempting to figure out what devices, if any, support the protocol, but I'm not finding may results. This kit looks like the only thing that I can buy right now that I can be confident would be compatible, and the Wi-Fi Press Release lists a few chips that are compatible, but I'm unsure of any consumer hardware that both has the chip and the correct firmware.

    Are there any production, consumer devices that I could use to test this?

    Any help would be appreciated.

    Anybody here work on a laptop they're actually happy with? What's the model and specs?

    Posted: 08 Aug 2018 08:07 AM PDT

    My lenovo shitbox cost like $1.5k and somehow android development makes it seem slightly better than a potato. My CPU and RAM are constantly maxed out all day, I can do nothing but watch when gradle is building, sometimes my colleagues gather around to roast marshmallows around the burning overworked ball of plasma that is me and my laptop.

    Honestly, I wonder how much more productive I would be on better hardware. At this point, it honestly makes me think I'd just earn back the cost of an upgrade in no time.

    So, are you happy with your laptops? If so, what are your specs? How much did it set you back? What do you recommend an experienced android dev get in Aug 2018?

    Mystery Vector Drawable Location

    Posted: 08 Aug 2018 01:46 PM PDT

    Hello /r/androiddev,

    Noob here. I am losing my mind a bit trying to figure out where in the world the source file for a vector drawable that is referenced in some sample code is stored at.

    Screenshot for reference: https://i.imgur.com/b8OMKuz.png

    The FloatingActionButton widget is referencing an "email" icon using the following:

    app:srcCompat="@android:drawable/ic_dialog_email" 

    The thing is, "ic_dialog_email" doesn't appear to exist anywhere in my project. Are there pre-packaged icons in the Support Library that's being referenced here?

    How the hell is "ic_dialog_email" being rendered if there's no SVG/XML file for it in the project?

    Any help in solving this mystery would be greatly appreciated.

    Thank you.

    ExoPlayer or MediaPlayer?

    Posted: 08 Aug 2018 04:14 AM PDT

    Our team is developing an application that streams audio and might also stream video in the future, we can't decide on which player to use for the project. Any recommendations?

    We understand ExoPlayer might consume more battery according to: https://google.github.io/ExoPlayer/battery-consumption.html

    Backend in Android

    What backend have you guys used in Android development? I know we can use firebase or firestore. I know there is also sqlite but that is locally for each phone.

    How to collect money from users and distribute to content creators

    Posted: 08 Aug 2018 02:45 PM PDT

    I am thinking about making an app that would let users pay for content created by other users. How would I go about distributing the money they pay to the creators? Does Google provide a way to do something like this or would I have to use external services?

    How the hell can you start with stuff like MVVM, Dagger 2, Kotlin, Data Binding, LifeData and other things?

    Posted: 07 Aug 2018 07:45 AM PDT

    If i search for MVVM, every tutorial at some point just assumes knowledge like "yeah we inject this thing here with Dagger, of course"

    When i try to search for Dagger, everything assumes i know how to use LiveData, but i don't even know how to use MVVM

    I mean if i try to learn MVVM

    I basically also have to learn

    -Kotlin

    -Dagger 2

    -LifeData

    -RxJava sometimes even

    -Data binding

    Seems like so many new things have been pushed out in the previous months that there is no way to really start without having worked with them before (like LiveData, which seems to require MVVM).

    How can i start learning when everything is so deeply connected?

    Issue with AndroidX and two-way data binding

    Posted: 08 Aug 2018 03:24 AM PDT

    Hi everyone, I've spent hours Googling this issue and haven't come up with anything. I'm in the process of migrating my app to AndroidX and it's gone smoothly apart from one data-binding related issue. Wherever I've used two-way data binding in an XML file (`android:text="@={viewModel.myStringLiveData}"`), it comes up with the following error:

    Unknown class: java.lang.String file://----/app/src/main/res/layout/my_fragment.xml Line:123

    Anyone have any ideas?
