    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(the one with java) and i found it pretty nice and the explanation was indepth, the only question i have is, is it outdated?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?

    Today I found my exact app with a different package name published on Google Play, is my admob account in risk ?

    Posted: 29 Dec 2019 03:45 PM PST

    Hey everyone,

    Today as I was checking the "app-ads.txt" section on my admob account, I was shocked that I found an app that is not even mine listed with my other apps.

    I clicked on the link to the play store page and found that the app is a clone of one of my apps, not just a clone but it's actually exactly my app with a different package name, someone took my app changed it's package name and uploaded it to play store, so the ad units IDs are my IDs .. etc

    And I am so worried that this is gonna bring my admob account trouble or something (invalid traffic maybe)

    What should I do now, is there any way I can report the app and get it removed or should I submit an update with new ad units .. any help would be so much appreciated !

    Thank you all

    Edit (update) : After checking the source code of the clone, he did indeed change the IDs but still I dont understand why the app appeared on my admob account's "app-ads.txt" section.

    Even if he forgot to change my admob's app ID in the manifest, that still doesn't explain it, cuz I already have some apps that had ads on them but I removed all ad units from admob to stop them from showing ads without having to submit an update, and these apps stopped appearing on the "app-ads.txt" section on my account ! so ...

    Note that I checked carefully all units, and I can confirm that all of them are replaced.

    Any ideas ?

    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}"}

    Android app template

    Posted: 30 Dec 2019 07:44 AM PST

    Maybe it's not the right place to ask, but I want to make an Android app with a similar style to Reddit Is Fun. I have every information saved in a local db and I just to make an app with the same style to display the db content. I'm not asking the source code of rif, but is there something I can start from? A template for example?

    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.

    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?

    First mobile app project with a client

    Posted: 29 Dec 2019 05:27 PM PST

    So this is my first month working as an Android Dev in my city. I am a fresh graduate and working in a start-up company, I mean this company was like founded this year November and the owner of the company is hiring inexperienced devs and right now there are 4 of us (fresh graduates 2 android devs and 2 web devs) working on this mobile app. We are in a mess right now for our client does not speak English very well and we are having a hard time communicating with them.

    ​

    Tbh, we spent 3 weeks on the design (I made the UI design) for the app. We don't have Senior so we are on our own. I know very well with Java. Can someone advise us on the steps that we need to make in order to pull off this project? What are the necessary requirements that we need to ask from the client (except budget) and the technology that we need to use? (they also need web app for admin). We really don't know now on what the client wants because of miscommunication. Help

    Do you experience a huge difference in number of crashes, between mobile/ desktop Google Play Console?

    Posted: 29 Dec 2019 11:06 PM PST

    I use both mobile Google Play Console ( https://play.google.com/store/apps/details?id=com.google.android.apps.playconsole&hl=en ) and desktop Google Play Console ( https://play.google.com/apps/publish ) to check app status.

    ​

    However, recently, I notice there is huge difference in number of crashes, between mobile/ desktop Google Play Console .

    ​

    mobile version reports there is around 700+ crashes in current production version. desktop version reports there is less than 30 crashes in current production version.

    ​

    Do you experience the same as I do? What do you do to rectify this?
