    Me & My Team developed this free marketing tool for App Install Advertisements

    Posted: 04 Feb 2021 05:53 AM PST

    Hey team!

    This is not a sponsored post or something.

    I've been following dev threads closely and came up with the idea of simplifying app advertisements so more & more developers can reach users and gain installs without spending tons of money on trying to find the best converting audience.

    We developed a free tool that simplifies Google App Ads. Advertising on Google is pretty complex these days. Even though their AI has been fantastic, for me it has always been difficult to properly set up a campaign and much more difficult to optimize upon results inside the Google Ads platform, We simplified those processes and I'd be more than happy to get you onboard to try so you can "shoot me" with questions & feedback regarding the platform.

    For now the tool is Free and we're not getting any profit out of it, since we've gotten access and approval from Google to use their API. In the near future we plan on integrating more Advertising Platforms (Facebook, TikTok, Unity, Apple Search Ads) so we can have a unified platform where developers can manage and scale their App Campaigns across all of the above mentioned channels. This is also the time when we plan on having a small subscription for users that are willing to manage multiple Ad Channels through our platform.

    Please let me know what you think about the idea! Your feedback and questions are highly appreciated.

    This is the tool: https://spingle.io

    Cheers!

    Now that Bintray and JCenter are shutting down, what should we do with the Android libraries that are hosted there?

    Posted: 03 Feb 2021 09:24 AM PST

    It seems like both services are shutting down in May.

    Like many other people, I use Bintray to publish my open-source Android libraries, so this is a little bit concerning. Are there any good alternatives?

    How do you monetize your app?

    Posted: 04 Feb 2021 06:13 AM PST

    Do you have challenges with app monetization?

    According to Statista: "Over 40% of app developers stated ensuring non-intrusive ad content was one of the biggest challenges while trying to monetize their apps. During a June 2019 survey of app developers from the United States and the UK, this concern ranked first among mobile app monetization challenges. In second place were concerns about app monetization efforts affecting the app experience negatively and contributing to churn."

    What do you think? What are your biggest challenges when it comes to monetizing an app?

    Big difference between AppStore and Playstore reviews

    Posted: 04 Feb 2021 03:25 AM PST

    Hello to all Android developers here! 👋🏻 I've pushed a really similar app to the Playstore and the AppStore. In the AppStore I got a lot of good and long reviews, also the bad reviews are very clear about what went wrong for the user and can be used as valuable feedback on how to improve the app. In the Playstore I got a lot more 1 star reviews and mostly with one sentence in the review which sometimes even don't make sense at all or with a lot of spelling mistakes. Just want to ask if you experience a similar behavior regarding reviews when compare AppStore with Playstore.

    Does anyone know a.mobile ads platform that pays in crypto?

    Posted: 04 Feb 2021 05:01 AM PST

    I saw an article around Vungle paying in BTC from 2018 but looks like they don't do that anymore, tried googling a bit but didn't find anything useful. Any tip? There are a few platforms for web advertising i don't understand why there aren't any for mobile.

    What do you think about using "Implementation by Delegation" in Activity

    Posted: 04 Feb 2021 12:44 AM PST

    I found myself implementing over and over one interface with the same implementation code in Activities of my Application. Those Activities have different "BaseActivity" classes so inheritance is not really an option. What I want - to create one class that implements this interface, and then in Activity delegate implementation to this class. Is it a good idea to use a Kotlin "Implementation by Delegation" for it? I feel like it's a bad idea to mess with the Activity constructors, but some how it works.

    Example:

    interface ExampleInterface { fun someMethod1() } class ExampleInterfaceImpl : ExampleInterface { override fun someMethod1() = Log.d("ExampleInterface", "someMethod1").run { } } class ExampleActivity private constructor( delegate: ExampleInterface ) : AppCompatActivity(), ExampleInterface by delegate { constructor() : this(ExampleInterfaceImpl()) override fun onCreate(savedInstanceState: Bundle?) { super.onCreate(savedInstanceState) someMethod1() } }

    If the existing app uses libraries no longer maintained but crucial to the app, how does Jcenter shutdown affect the app?

    Posted: 03 Feb 2021 11:22 PM PST

    Assuming the app functionality will stop working for that library ...

    How should app developers respond to this situation?

    What are the available options to tackle this issue? Please list them all, so it can be evaluated.

    Is it wise to somehow for app developers to include the open source library directly in the app, if so how or what other options are there?

    Cache size not going down after deleting data from rooms DB?

    Posted: 03 Feb 2021 07:30 PM PST

    Hi, I'm working on a movies app and everytime the user goes to a movie details it saves the movie in the db, I made a worker so it deletes all of those movies after a week but it turns that the cache size remains the same even though that table is empty, any ideas?

    How can I be sure that my code is obfuscated or not?

    Posted: 03 Feb 2021 02:53 PM PST

    Hey i'm having issues with my buildType section on my gradle file.

    What happends if i set on release build type minifyEnabled true and debuggable true? Typically minifyEnabled = true on release build and making it debuggable likely prevents it from doing the obfusctation right?

    How can I be sure that my code is obfuscated or not?

    release {

    minifyEnabled true

    debuggable false

    signingConfig null

    shrinkResources true

    zipAlignEnabled true

    proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'

    }

    }

    The only way i know is to verify that shrinking and obfuscation has been applied to my project is to check for the existence of the mapping file on ` android\app\build\outputs\mapping. `

    NOTE: When i create a build with the debuggable flag on true the mapping file is being created, but I'm not 100% sure if my code is obfuscated or not.

    In conclusion, I just want to debug an application with the obfuscated code

    App developers! Do you use third party libraries? Credits?

    Posted: 04 Feb 2021 02:05 AM PST

    If so, how many? How do you give credits? I write my own stuff and have been avoiding non-google libraries for this reason. Apache 2, 3 licences are a bit too lawyer-y for me and don't want to get in trouble/have my app taken down for improper credits. Or that isn't a thing?

    Why does android still not support wideband bluetooth headsets in 2021? Max mic capture is 8khz in api ??!!

    Posted: 03 Feb 2021 05:57 PM PST

    Seems like all bluetooth headsets sound horrible with android. Now I believe I know why: mic capture api only supports 8khz capture even if virtually all headsets support 16khz (hfp 1.6 profile from 2011). Is this true?!!

    Note: not an android dev, just trying to use my $200 headset with duo without sounding like I'm talking through a shortwave radio

    From: http://developer.android.com/reference/android/media/AudioManager.html#startBluetoothSco()

    The following restrictions apply on input streams:

    the format must be mono

    the sampling must be 8kHz

    Accelerating development cycle by eliminating compilation and installation of apk

    Posted: 03 Feb 2021 11:12 PM PST

    You can greatly increase the development iteration cycle on Android if you eliminate having to compile your code and install your code changes (apk). This can be done if...your application is a single file that contains all of your resources and code (in script form) that is simply adb-pushed to your device and then played in a player app (taking about 1 second). I've done this in my side project, here's a short clip: https://youtu.be/uPd8iaPPA0s?t=33

    Power off device programmatically from device-owner app (Android 10 on - non rooted)

    Posted: 03 Feb 2021 10:55 PM PST

    Is there any way to power off a device since the update of policies in Android 10?

    I have dedicated devices that can virtually do anything on the system, but the only thing missing is the power off.

    I tried most of the solutions around but none work so far.

    Most links on SO refers to old solutions, or require the device to be rooted

    Distributing a private app to users who are not tech savvy

    Posted: 03 Feb 2021 11:44 AM PST

    In an upcoming event / field test I would like participants to install an open source Android app, which they can (and will) uninstall later on. The app is distributed in source code form only (i.e. github) since it requires an API key for some Google services.

    I know I can build an APK and send them a link to download it, but then they need to: approve a message that says the file is harmful, enable installation from unknown sources (which does not have a consistent UI across different phones / manufactures), allow the installation itself, select "install anyway" when the "Play Protect" block warning pops up and then see the "send app for scanning?" message anyway. I am looking into a way to simplify this process.

    Is there any way to distribute the app while making it simpler for users to install, being similar or close to the play store experience? I prefer to avoid collecting email addresses or requiring registration.

    I thought about publishing to the Play Store in the internal track and distribute the opt-in link, but there is a 100 users limit and I am not sure I can remove users without asking them to actively leave the testers list. There would likely be future events.

    Thanks!

    Samsung can't install apps from Github but other devices can

    Posted: 03 Feb 2021 05:02 PM PST

    Pretty much title, I have tested downloading my open source app in other devices (OnePlus running LOS and Pixel running LOS), but the same app does not work when installing on Samsung. Is there anything that could cause this in the app configuration?

    EDIT: the app downloads and begins installing but fails with message "App not installed". Permissions to install are being granted on device.

    What are some general unsaid practices that app developers follow while doing Java Android dev

    Posted: 03 Feb 2021 09:24 PM PST

    Hi.

    I am a student app developer, and I set out with a few of my friends and the backing of a college committee to develop an app for people in India, mainly women, who may use it in times of distress or emergencies.

    I had experience in Java before, but Android increased that experience exponentially, to the point that I now feel comfortable using it for all purposes.

    My question to the community is, what are some unsaid or implied 'good practices' that all developers follow, to make sure their code and their app in general is top-notch in quality?
