    Android interview preparation in 2.5 months

    Posted: 31 Jul 2018 09:24 AM PDT

    I have recently resigned from my position and am currently looking for a job. I have 3 months of notice period and I want to get better at cracking interviews.

    I am having 4.5 years of experience and am pretty comfortable with most of the Android components. I have been preparing myself on improving in background processing (haven't used services / intent services), user experience, MVVM, RxJava and writing unit test cases. I am also brushing up on Java concepts.

    I am used to handling multiple projects at a time and some where it has affected ways in which I plan things (ignoring writing test cases).

    I wanted suggestions and tips on how to prepare in the 2.5 months of time I have. What are the questions / concepts to prepare on given my background?

    How to write your Résumé to get hired

    Posted: 31 Jul 2018 03:09 AM PDT

    Just in case this helps anyone I just recently published a post about how to rewrite your résumé to get hired. Mostly for anyone recently getting into Android development & looking to transition it into a career choice but maybe others will benefit also.. It's definitely not pretty but it's what's worked consistently for me the past 7 years I've been at this so hopefully someone finds it useful :)

    I can't seem to remove my title bar and I can't figure out why...

    Posted: 31 Jul 2018 02:51 PM PDT

    I've looked through plenty of Stack Overflow posts on the topic but can't seem to find a solution that works. All I want to do is remove the title bar at the top of my activity. I have a feeling it has something to do with the library I'm using to create a drop down calendar as it had me paste in some xml code to ensure it is functioning correctly.

    Manifest file

    Android App Bundle Has Invalid ProGuard File

    Posted: 31 Jul 2018 08:50 AM PDT

    When trying to upload my bundle to the play store, it says the proguard deobsfucation file is invalid. I don't see how though as everything is commented out besides these 3 lines:

    -keep class com.google.firebase.**
    -keep class com.firebase.ui.auth.data.client.AuthUiInitProvider { *; }
    -keep class androidx.lifecycle.ProcessLifecycleOwnerInitializer { *; }

    Any help would be greatly appreciated!

    Question for devs with experience in Instant Apps

    Posted: 31 Jul 2018 04:08 PM PDT

    I'm thinking of re-working my app in order to offer an instant app, but I have some doubts.

    How much time did it take? I know it won't be the same for all apps, but I've no idea if its work for a day, a week or a couple months.

    Also, do you think it was worth it?

    Thanks!

    AltBeacon library detection beacons issue

    Posted: 31 Jul 2018 06:30 AM PDT

    Hi everyone! I need some help with developed android application. Application should detect beacons (I use AltBeacon library for it), than requests some additional data from server and shows it to user. When application is active, there are no issues. But when application is in background mode there are 2 issues: It can stops working after few days There can be quite big delays for detecting beacons (1-2 hours for example) when application is inactive for 1 day for example. I use foreground service for preventing killing of application by Android. Also I use partial wake lock for preventing stand by mode. And also I use alarm manager and RTC wakeup for the same purposes. Are there any additional ways to prevent beacons detection delays and stopping application after few days? Thanks.

    Help!!! Need an idea for BCA final project.

    Posted: 31 Jul 2018 08:05 AM PDT

    Hey guys, I'm studying BCA final year and I really need some ideas on what to do for the final project. Many project centres contacted me and sent me some prebuilt project abstract.Most of them feels lacklustre and plain to me and I don't think I'll never learn anything if do a project made by them . I'll try to link some topics if i can in the comments.

    Some Outstanding and Exciting Reasons to Become an Android Developer

    A question about android camera

    Posted: 31 Jul 2018 11:30 AM PDT

    Hello, I am a noob in android app development. Today I have an idea of developing app that can 'record' high fps video/slow motion video on android phones that are 'not supposed to do so' (Limited by configurations in /system/etc/media_profiles.xml and other related configuration files). The idea is to take pictures quickly (e.g. 60 pictures in 1 second) and then combine the pictures together to form a video. However, there are 3 problems that I might run into:

    1. Does Android Camera API 2 limits the number of pictures that could be taken in 1 second? If yes, how many?
    2. Besides the (possible) limiting factors of Android Camera API 2 and hardware, what are the other major limiting factors of how many photos that could be taken in 1 second by android camera?
    3. What is the feasibility of creating this app?

    Thank you!

    Looking for programming friend!?

    Posted: 30 Jul 2018 10:42 PM PDT

    I have been working with java and android for about 3 years now and have a solid foundation, I have developed one app on the store while a friend of mine worked on the iOS version. I am okay on Xcode and Obj-C/Swift.

    I have learned a lot from him and has helped me overall as a programmer. I was wondering if anyone out there would like to chat and work on a project together. Help each other learn and maybe build something together as well.

    Send me a private message if you are interested?
