    Posted: 30 Dec 2019 02:56 AM PST

    This thread is for simple questions that don't warrant their own thread (although we suggest checking the sidebar, the wiki, our Discord, or Stack Overflow before posting). Examples of questions:

    • How do I pass data between my Activities?
    • Does anyone have a link to the source for the AOSP messaging app?
    • Is it possible to programmatically change the color of the status bar without targeting API 21?

    Important: Downvotes are strongly discouraged in this thread. Sorting by new is strongly encouraged.

    Large code snippets don't read well on reddit and take up a lot of space, so please don't paste them in your comments. Consider linking Gists instead.

    Have a question about the subreddit or otherwise for /r/androiddev mods? We welcome your mod mail!

    Also, please don't link to Play Store pages or ask for feedback on this thread. Save those for the App Feedback threads we host on Saturdays.

    Big Nerd Ranch still an option in 2019?

    Posted: 30 Dec 2019 05:09 AM PST

    i'm starting to learn android app development, at first i thought of udemy courses but they don't explain everything going on and they don't implement good practices or any software architecture like MVP etc. I skimmed through the Big Nerd Ranch for android 3rd edition (the one with java) and i found it pretty nice and the explanation was indepth, the only question i have is, is it outdated? the 4th edition came out but its in kotlin and i want to do it in java first as i am a beginner. Could you guys help me with resources or a path maybe?

    Will using RamDisk decrease build time?

    Posted: 30 Dec 2019 05:36 AM PST

    Did anyone tried using Ram memory instead of SSD/HDD for your project? How faster is it?

    You need just two steps:

    Linux: https://www.techrepublic.com/article/how-to-use-a-ramdisk-on-linux/

    Windows: http://www.ltr-data.se/opencode.html/#ImDisk

    macos: diskutil erasevolume HFS+ 'RAMDisk' hdiutil attach -nomount ram://8388608

    Then in your grade: allprojects { if (new File("your_ram_disk_path").exists()) buildDir = "your_ram_disk_path/build/${rootProject.name}/${project.name}"}

    Converted Activity to Fragment and now my code is littered with warnings, what is the best practice for dealing with this?

    Posted: 30 Dec 2019 04:13 PM PST

    Hi.

    I'm converting my app to work as a single activity application using jetpack navigation. One issue I'm really concerned about is this clusterf*ck of warnings produced from every getContext and getActivity in my code.

    I have read time and time again that storing a reference to context or an activity is a bad practice due to potential memory leaks, but how else can I remove all of these warnings without null checking 1000 times?

    What's your continuous integration and testing setup look like for full UI testing across devices?

    Posted: 30 Dec 2019 04:07 PM PST

    I'm working on a new product that needs to have a very reliable android app.

    I want to have full continuous test/integration of the code and the integration of the UI.

    Right now I'm using circleci and it tests all my code but I want it to test our app.

    What so you guys use for production?

    I need something I can invest in and have this solved long term and don't mind paying for a SaaS solution.

    Any reliable crash report SDK tool? Is Firebase Crashlytics good?

    Posted: 30 Dec 2019 07:39 AM PST

    Recently, we notice that the crash report from Google Play Console is not reliable.

    There are around 766 crashes incidents in statistics page - https://i.imgur.com/vEPBUPF.png

    However, in ANR & crashes page, there are around 50 crash stack trace being shown - https://i.imgur.com/xRxZlCD.png

    Do you use any 3rd party crash report SDK, to help you obtain a more reliable crash report and stack trace?

    If yes, can you kindly recommend one? Thanks.

    Exploring "architectures" article

    Posted: 30 Dec 2019 02:46 PM PST

    Hey guys,

    for the past years in my software developer career I was trying to master software architectures and understand them and is this is a never ending path I wanted to summarize my thoughts.

    I've written an article about my experience with designing software architecture, opinions on MVx patterns and other things I found important.

    It is pretty much written to take on things in general but there are some specific platform related examples.

    Open to feedback here and any kind of related comments and opinions.

    Need help in building an app which works for different sizes of screen (Android version is the same or higher)

    Posted: 30 Dec 2019 10:08 AM PST

    I am building an app for a client whose current version was only limited to Samsung Galaxy E tabs. The client wants to build a new version of the app from scratch as they want to include newer technologies. The app is a basic survey app but it is meant for old people. They want the app to work on tabs as well as phones. Now I have no clue as to how difficult it is. I think it should be easy if I use relative layouts? Any help would be appreciated.

    Thank you.

    What subjects and/or tools would you suggest to someone (new to android dev or has outdated knowledge) to learn in 2020

    Posted: 30 Dec 2019 03:18 AM PST

    I used to be proficient in android dev but wasn't able to hold on to that knowledge bc of my profession now (web dev) , but would like to re-learn it.

    I'm afraid that just by reviewing my notes on techniques and tools i used from my past projects would probably outdated by now since I do know how fast technology evolves.

    I would like a fresh start

    Yesterday I published my app and before I published my app, I changed the ad ID's from the test ID's to the real ID's but when I launched my app the ads didnt show up, is this just because it wasnt downloaded via google play or is this a bug?
