    Am I on the right track?

    Posted: 29 Mar 2022 08:34 PM PDT

    Hi, I hope this doesn't break the rule #2 because it's not really a technical problem or anything like that. If it does please let me know and I'll be happy to inquire elsewhere.

    I am a college student and I am hoping to get into android development to start my career, because I already have a game published on the app store and I have quite a lot of experience with Java. I've been having a lot of fun tinkering with Android Studio, and I've made some progress on a basic budgeting app. I'm not asking you to look through my code or anything crazy. However, other people's github apps seem to be structured quite differently from mine and I'm worried that I'm doing something colossally wrong. I haven't been able to find much specific help in terms of starting your first app (other than setting up android studio, github, etc.) The project is available at https://github.com/AlexJMoore03/Transactions . If you have a few minutes I'd greatly appreciate it if you could view the basic folder structure and everything and just see if there's any major red flags that I'm doing something significantly wrong. Thank you so much.

    Creating an app for a client, do's and don't

    Posted: 29 Mar 2022 12:05 PM PDT

    Next week I'm meeting with a client that hired me to develop an app for him and eventuality uploading this app to play store.

    I have no experience at all with working with clients and uploading to the play store.

    How should I prepare for the meeting? What should I ask him and what should I know? And any tips for uploading to the play store? I know that the project will eventually be a patent and they asked me to sign an NDA

    Thanks!

    After how many app downloads should ads be integrated?

    Posted: 29 Mar 2022 04:19 PM PDT

    Hello,

    I read somewhere that it's good practice to integrate ads after 100K app downloads. What are your thoughts on this idea? Have you had any successful experience implementing it?

    Hi androiddevs!
    I was wondering how would one go about implementing this kind of UI animation. (Check Video)
    I was thinking of using android transitions API along with state machines for modelling every possible view states in the animation.
    I would like to get ideas for solving this problem. Thanks in advance!

    Feedback on app needed

    Posted: 29 Mar 2022 08:41 AM PDT

    Hi,

    I am trying to land my first job as Android Developer. In order to learn needed skills, I am developing an app called Video Space. While It's still not finished, I do believe It is at the point where I could use some feedback. You know things like: overall code quality, are test cases all right, some additional features that are worth implementing, maybe bugs I've missed etc. In short, I'd appreciate any feedback you can give me.

My Question here does stock application process image/video "like video stabilization" better than open source application ? or those processing image/video perform inside phone processor despite whatever application we use ?

    Distribution questions

    Posted: 29 Mar 2022 07:57 PM PDT

    Hi all,

    I've developed an app that is fairly unique to a niche group of businesses operating with recipe menus that are trade secrets. This app displays the recipes in an accessible and functional way.

    I can't just offer the app on the Google play store, because the recipes are, again, trade secrets. I have to limit access to the app to people I can verify. But, i expect to sell well over 1000 copies.

    I considered Google workspace but the per user per month fees really make that option rather distasteful. I'm wondering if there is a better way to distribute this app to my customers, while protecting btih my and their properties.

    Thanks so much for your help.

    Competitors constantly faking reviews and ranking higher because of it... Anything that can be done?

    Posted: 29 Mar 2022 06:03 AM PDT

    These crappy scammy apps are so obvious about their fake reviews. Almost no downloads and yet somehow they get exactly 5 5-star reviews every single day. Always written in poor English and clearly know nothing about the app because they comment on features that aren't even available.

    Very frustrating that Google can't pick up on this obvious abuse. Any ideas?

    Resume review for non-EU candidate (1 YOE) applying to jobs in the UK from Italy

    Posted: 29 Mar 2022 12:25 PM PDT

    I have two resumes that I would like to get reviewed. Both of them got 75+ scores on resume worded but I would like to know if they are good enough to be used for applying to jobs:

    Resume 1: This is related to roles that involve Python and/ or computer vision

    Resume 2: This is related to roles that involve Android app development

    Is it normal for Jetpack Compose previews to be slow to rerender?

    Posted: 28 Mar 2022 09:26 PM PDT

    I come from Flutter and trying to learn native Android development. I have a small code for testing out the preview build & refresh time for jetpack compose on Android Studio:

    ```kt @Composable fun Greeting(name: String) { Button(onClick = { println("Hello $name!") }) { Text(text = "Hello $name!") } Text(text = "Hello $name!", color = MaterialTheme.colors.primary) }

    @Preview(showBackground = true) @Composable fun DefaultPreview() { ComposeTodoListTheme { Greeting("World") } } ```

    Unfortunately, even with a UI this small, building and rendering the preview takes such a long time (about 15 seconds or more), loading the initial preview is much longer (takes 2 minutes or more). I don't know if this is normal or not.

    This could just be because my machine is too old and low spec, but I'm not sure: i5 2500 16 GB DDR3 1600mhz GTX 750 Ti

    I've been using this machine for developing Flutter applications and it is much faster due to hot reload.

    I'm not expecting speed to that of Flutter for jetpack compose but half a minute just to see a color change is too long.

    Dev console: Updating an app during staged rollout

    Posted: 29 Mar 2022 09:01 AM PDT

    Hi. We've uploaded a new APK (APK2) to production with 50% staged rollout. Other 50% is reserved for the old version that was in production before (APK1) Now, we've a small fix that we'd like to roll out to the same 50% of users (APK 3). What are the steps to replace APK2 with APK3?

    According to the docs:

    • When you do a staged rollout of a new release before completing the rollout of the previous release, the new release will use the same group of users as the previous release (depending on the percentage of the rollout).

    APK 3 passed the review in Closed testing, now when I want to promote it to production and set the same 50%, will it replace APK2, and not APK1?

    Spen inputs to mouse inputs

    Posted: 29 Mar 2022 04:29 PM PDT

    Hi, So a little backstory- i bought tab s8 for work (im grading and annotating med scans) but it turns out that the website apps, where I do my work, don't recognize Spen inputs, only mouse. So i bought bluetooth mouse an it works just fine but i want to use my pen to annotate and paint.

    My question is if its possible to make an overlay that changes spen inputs to mouse inputs and of course pen touch to lmb click (and hold). If it is possible to make this, how much would be considered as adequate payment?

    Language for Android interviews

    Posted: 29 Mar 2022 03:38 PM PDT

    I am currently practicing leetcode and was wondering what language should be used for interviews? Is it required/expected for an Android engineer to use Java or Kotlin for interviews, or would they have no problem with me using python?

    curious about using facebook in another app

    Posted: 29 Mar 2022 01:55 PM PDT

    Hi,

    im doing a project on helping seniors adapt to social networks and decided to create a simple social messaging app.

    i was reading some research about using facebook on a TV and it occurred to me that it might be possible to do this with an app.

    what i mean is, having an app with very simple UI design (better for seniors) that could interact with facebook like sharing pics on facebook and stuff.

    is there a way/API that could enable this?

    since im new to mobile dev i decided to ask the pros here.

    ps: the api used to interact with facebook using a TV has long expired i believe.

    Import old project into Android Studio?

    Posted: 29 Mar 2022 12:35 PM PDT

    I am trying relentlessly to import this project into Android studio as part of my Udacity Android development courses. I tried everything from forking on GitHub and cloning it into my Android studio to changing the Gradle settings, the Java version, following the recommended settings by android studio, etc.

    https://github.com/udacity/ud839_CustomAdapter_Example

    Nothing seems to be working. I keep getting errors. Each time I fix the error I get another error. Can someone please guide me as to what exactly is the proper procedure for importing an older project into the android setting and updating the settings? I seem to be experiencing the same issue every time I am completing online courses. The existing projects appear to be completed through older versions of Java and Android studio. Any help is greatly appreciated. Thank you

    Are there any specific IP block of Google Play Reviewers

    Posted: 29 Mar 2022 01:38 PM PDT

    Hi 🙋🏻‍♂️

    As you know if an app has a login feature, google play console wants a login credential of the app. It is understandable but I want to keep this data safe and only usable for Play Store reviewers. That is why I should learn their IP block the to access given data and others should be restricted. This way I can keep the data and the app safe without any backdoor.

    How can I color Circiural Reveral Animation in Android Activity Transition?

    Posted: 29 Mar 2022 09:42 AM PDT

    While searching for an animation with a circular transition on the internet, I came across the code below.. but I want to improve it, can you help with this?

    ​

    1. First of all, there is an error that it does not open exactly from the targeted place, but I could not find it.

    2. I want to color the background during transition

    ​

    how can I do these? Like this= https://medium.com/@gabornovak/circular-reveal-animation-between-fragments-d8ed9011aec

    ​

    ​

    public class RevealAnimation { public static final String EXTRA_CIRCULAR_REVEAL_X = "EXTRA_CIRCULAR_REVEAL_X"; public static final String EXTRA_CIRCULAR_REVEAL_Y = "EXTRA_CIRCULAR_REVEAL_Y"; private final View mView; private final Activity mActivity; private int revealX; private int revealY; public RevealAnimation(View view, Intent intent, Activity activity) { mView = view; mActivity = activity; if (intent.hasExtra(EXTRA_CIRCULAR_REVEAL_X) && intent.hasExtra(EXTRA_CIRCULAR_REVEAL_Y)) { view.setVisibility(View.INVISIBLE); revealX = intent.getIntExtra(EXTRA_CIRCULAR_REVEAL_X, 0); revealY = intent.getIntExtra(EXTRA_CIRCULAR_REVEAL_Y, 0); ViewTreeObserver viewTreeObserver = view.getViewTreeObserver(); if (viewTreeObserver.isAlive()) { viewTreeObserver.addOnGlobalLayoutListener(new ViewTreeObserver.OnGlobalLayoutListener() { @Override public void onGlobalLayout() { revealActivity(revealX, revealY); mView.getViewTreeObserver().removeOnGlobalLayoutListener(this); } }); } } else { view.setVisibility(View.VISIBLE); } } public void revealActivity(int x, int y) { float finalRadius = (float) (Math.max(mView.getWidth(), mView.getHeight()) * 1.1); Animator circularReveal = ViewAnimationUtils.createCircularReveal(mView, x, y, 0, finalRadius); circularReveal.setDuration(300); circularReveal.setInterpolator(new AccelerateInterpolator()); mView.setVisibility(View.VISIBLE); circularReveal.start(); } public void unRevealActivity() { float finalRadius = (float) (Math.max(mView.getWidth(), mView.getHeight()) * 1.1); // I think the error is here but nothing has changed Animator circularReveal = ViewAnimationUtils.createCircularReveal( mView, revealX, revealY, finalRadius, 0); circularReveal.setDuration(300); circularReveal.addListener(new AnimatorListenerAdapter() { @Override public void onAnimationEnd(Animator animation) { mView.setVisibility(View.INVISIBLE); mActivity.finish(); mActivity.overridePendingTransition(0, 0); } }); circularReveal.start(); if (MainActivity.getInstance()!=null){ MainActivity.getInstance().mainActivityBottomBar(); } } }

    StartActivity

    ​

    int revealX =(mainBottomBarLayout.getLeft() + mainBottomBarLayout.getRight()) / 2; int revealY =(mainBottomBarLayout.getTop() + mainBottomBarLayout.getBottom()) / 2; Intent intent = new Intent(MainActivity.this, intentClass); intent.putExtra(RevealAnimation.EXTRA_CIRCULAR_REVEAL_X, revealX); intent.putExtra(RevealAnimation.EXTRA_CIRCULAR_REVEAL_Y, revealY); startActivity(intent); overridePendingTransition(0, 0);

    Style

    Question about Google Play app signing

    Posted: 29 Mar 2022 02:33 AM PDT

    Im trying to understand the App signing process for Google Play.

    When creating a new app App Signing by Google is standard in which they sign apk's, though Im not allowed to download the signing keys. When I Generate Signed bundle in Android studio I must create a keystore file and Android studio exports a .pepk file the first time I do it. I dont have to upload this keystore or .pepk file anywhere and Google Play just accepts my signed App Bundle.

    Coming from the Apple App Store world Im used to having to create a Distribution Certificate and upload it to AppstoreConnect (Like Google Play console), but for Google Play I dont even get the option to upload my pepk file or my keystore file.

    When I then Generate a new signed app bundle for an update, how does Google Play know that the build was made by the same machine as before? What if I change machine and try to Generate and upload from it?

    Full Android RSNAV Car infotainment outdated and buggy

    Posted: 29 Mar 2022 07:36 AM PDT

    I have this RSNAV S1 device in my car, Basically a android tablet with some cool bits like CANBUS decoder to grab button inputs. but it has some massive downfalls. 1 the devs was going to support it for years to come but as soon as i got my one they ditched the S1 due to issues they couldn't fix.

    The issues,

    1. Sound bugs out due to the chip getting overloaded. (if you pause music before leaving the car it wont but but if u leave sound playing and turn the car off it will bug out and need a reboot to fix)
    2. Its stuck on android Android 6.0 MARSHMELLOW

    specs are

    • CPU: 64Bit MTK8783 octa core Cortex A53 1.3 GHz
    • GPU: Mali-T720
    • RAM: 2GB
    • ROM: 16GB
    • Network: Built in GSM, CDMA, UMTS(3G), 4G LTE Modem, Wifi 2.4ghz/5ghz b,g,n, Bluetooth 4.0 (HFP,A2DP)
    • Inputs: BACK UP CAM(Composite), AUX1(Composite), AUX2(Composite), USB 2.0 x 1, TF(MicroSD) card x 1, SIM card x 1

    It cost me a good £550 and alot of blood and tears installing it. I was wondering seeing as there's alot of unhappy S1 owners, How hard would it be to create my own custom android install and work around the issues? Or how likely and expensive would it be to hire someone to make me a custom rom?

    https://rsnavwiki.com/Techspec

    I have abundance of firmware files for the device as the owner of RSNAV was helping me try and fix the issues until he abandoned it. seems u can flash firmware's via a security screen in the rsnav
