    Interesting find about the upcoming navigation library?

    Posted: 02 May 2018 07:19 AM PDT

    I was just writing some lint checks, and found the http://tools.android.com/tips/lint-checks website. Didn't think much of it, but decided to check out new issues, and there's one that's called InvalidNavigation that says:

    InvalidNavigation ----------------- Summary: No start destination specified Priority: 3 / 10 Severity: Warning Category: Correctness All <navigation> elements must have a start destination specified, and it must be a direct child of that <navigation>. 

    I know it's pretty much confirmed that something related to the navigation will come to the arch components (from the description of session about in-app navigation on I/O -- https://events.google.com/io/schedule/?sid=f01ba5cd-7dc7-4028-a1c5-55140ea62bb1) but it's interesting to see things popping up nevertheless.

    Also interesting to see some what I think are GDPR-related checks (RiskyLibrary, OutdatedLibrary) and Kotlin interoperability ones (KotlinPropertyAccess, LambdaLast, NoHardKeywords, UnknownNullness).

    RxJava to Kotlin coroutines – Chris Banes

    Posted: 02 May 2018 11:26 AM PDT

    Do you see Kotlin overtaking Java in the future of Android development?

    Posted: 02 May 2018 12:51 PM PDT

    I hear a lot about Kotlin, and I haven't looked to much into it. I even know android developers who completely swear by Kotlin and say it is much better for app development than Java. What do you guys think about this?

    Can I delete and add geofences to stay within the 100 limit?

    Posted: 02 May 2018 02:02 PM PDT

    So I'm making an app that has more than 100 geofences across the city. My idea is to have a smaller number of geofences in each district that are always active. If one enters a district it will delete the previous geofences and add the ones only in this district, up to the 100 limit. Is something like this possible?

    Where to start learning java and openCV

    Posted: 02 May 2018 08:56 AM PDT

    I just started a project where I use my phone and an arduino as a smart car and I want to do object detection/line following through my android phone, I have about 4 months and was wondering where I should start. I have decent c++ knowledge and good python knowledge already if that helps. Thank you

    What's the minimum number of downloads your app should have, for using simple admob ads to be worth it?

    Posted: 02 May 2018 12:36 PM PDT

    I know this question is kinda broad, since there are different types of ads, but I'm looking for an estimate. I have an app with 50 daily downloads on average, and I haven't put ads in it or anything and want to know if i should. I know a lot of people have personal experience with this, so I'd like to hear your input. Thanks.

    Android Dev - Resume Feedback?

    Posted: 02 May 2018 01:24 PM PDT

    Hello,

    I apologize in advance if this is the wrong forum for this, but in my search it looked like there has been info/feedback to others on their Android resumes.

     

    Looking to get some feedback on my resume as I have not gotten many interviews: https://docs.google.com/document/d/1-hCGkINLOUXLYj9nBnFAubI53KhR7JNW6EgfNouXn5U/edit?usp=sharing

     

    Thanks!

    How best to engage with users regarding testing and tracking down issues?

    Posted: 02 May 2018 05:29 AM PDT

    I have an app ShaderPaper that recently got reviewed on a German blog site. Since then I have gotten a few one star reviews because they say it causes bootloops.

    This is a live wallpaper app that uses OpenGL shaders. I have tracked it down to Kirin chipsets but being based in the US Huawei and Honor phones which have it aren't easy to come by.

    I have reached out to the article writer and replied to all people who reviewed about the bootloops. Unpublished

    What is your experience?

    How do you go about trying to resolve issues specific to devices?

    How do you get users to engage in an open dialogue concerning help with fixing issues, even when there is a language barrier?

    How to save all the variables of an activity to a file before quitting that activity?

    Posted: 02 May 2018 03:48 AM PDT

    I'm almost done with developing a flowchart drawing application. What's left is adding a "save diagram" functionality. All the shapes, texts and arrows are stored in a few ArrayLists and variables so saving those and restoring them later on when user wants to go back to a previously drawn diagram will be enough.

    I don't know what's the best way to do this though. Here are a few questions:

    1-) I need to ask the user whether he wants to save the diagram or not once he presses the back button, which destroys the drawing activity and goes back to the previous activity called MainActivity. What function should I override? onStop or onDestroy?

    2-) What's the best way of saving variables to a file? I'm planning of having a seperate file for each diagram that includes all the arraylists containing shapes, texts and arrows. These variables are stored in a Java class called DrawingSurface (the canvas). Is writing this object of class DrawingSuface to a file using OutputStream sufficient or do I have to serialize or decode/encode etc?

    Is there a non deprecated way of getting frequent background location updates prior to android 8.0?

    Posted: 02 May 2018 12:21 PM PDT

    According to this article, google now limits the number of location requests an app running in the background can make. It does not, to my understanding, directly affect devices prior to android 8.0. However, google's APIs such as fused location provider are subject to the limitation, too. Therefore, apps, that use these API's cannot access frequent location updates, too. So there should be a way to avoid using these API's to support frequent background location updates in devices prior to android 8.0, right? If so, then how?

    The easiest bottomsheet in town

    Posted: 02 May 2018 07:54 AM PDT

    Hi, this is my first public repository I'm releasing, so please go easy on me!

    I couldn't find any bottomsheet that was "easy" to implement so I made one that I believe works good, and is in Kotlin!

    https://github.com/wasdcantmove/bottomsheet

    Hope someone finds it useful.

    Unidirectional data flow on Android: The blog post (part 2)

    Posted: 02 May 2018 04:03 AM PDT

    In your opinion, is it possible to become a hirable android dev by self learning through tutorials instead of taking college courses?

    Posted: 02 May 2018 10:13 AM PDT

    I graduate this week with a degree in Psychology, but I have also completed enough CS courses to get be eligible to pursue a master's degree in CS, so I'm trying to figure out what to do.

    I got into developing for android for CPA purposes (mobile advertisement) and basically learned how to create an app from watching youtube tutorials on all the parts I would need in my own application (very simple stuff). Now I'm following youtube tutorials on cloning different major apps and I feel as if I'm learning a lot, more than I do in CS classes in general, mainly because it's more fun.

    Do any actual developers learn this way? Is this a good strategy for trying to break into the field?

    Newbie programmer

    Posted: 01 May 2018 06:14 PM PDT

    I've made a dice roll application as one of my first apps. I want to put it up on the play store. My app is nothing magical, but I feel proud of myself after creating my first app. I need advice on what do you guys use to create app icons, how can I make my app visually appealing to users, and any free alternatives to photoshop? I appreciate all answers/suggestions.

    Implementing Native Ads with Firebase Admob

    Posted: 02 May 2018 01:49 AM PDT

    To me, native ads are... interesting. They're the most aesthetically pleasing (or least displeasing, let's be real, they're ads) because you determine how they look like, to the point that they can just blend in with the rest of your content.

    They are however not the most straightforward to implement and it feels crazy trying to learn it from the documentation. I summarised the most important points in hopes that others would find this helpful.
