    Permission READ_PHONE_STATE misleading my users

    Posted: 02 Jan 2020 05:32 AM PST

    I get quite a few complaints about this permission in my app. I just want to know when a phone call comes in so that I can stop the audio playing.

    The android reference for this permission says:

    READ_PHONE_STATE Allows read only access to phone state, including the phone number of the device, current cellular network information, the status of any ongoing calls, and a list of any PhoneAccounts registered on the device. 

    But the system popup from ActivityCompat.requestPermissions says:

    Allow <app> to make and manage phone calls 

    I do explain what the permission is for before asking, but my users think I may be up to something dodgy, as I appear to be asking for permission to make phone calls.

    Am I doing this correctly? Is there any way of avoiding the "make and manage" calls description when the permission clearly doesn't allow this?

    Edit: For completeness my full permissions list is:

    <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" /> <uses-permission android:name="android.permission.READ_PHONE_STATE" /> <uses-permission android:name="android.permission.INTERNET" /> <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" /> <uses-permission android:name="android.permission.BILLING" /> <uses-permission android:name="android.permission.RECORD_AUDIO" /> <uses-permission android:name="android.permission.WAKE_LOCK" /> <uses-permission android:name="android.permission.MODIFY_AUDIO_SETTINGS" /> <uses-permission android:name="android.permission.BLUETOOTH"/>

    AdMob Developers who have been banned recently, has anyone successfully appealed?

    Posted: 01 Jan 2020 11:53 PM PST

    In the latest massive ban wave by AdMob, many developers have been banned for Invalid Activity, without any explanation or warning. My account has also been banned, almost two months ago and I tried to appeal multiple times but I am getting the usual responses from what seem to be bots aka "The AdSense Team"

    The responses usually go by: thank you for additional info, unfortunately our specialist has confirmed that we are unable to reinstate your account, thank you for understanding

    So, has anyone who has been banned recently, or any who has been banned by AdMob successfully appealed?
    My account was disabled instantly without previous warnings or violations, and I simply refuse to give up until this is resolved.

    Make babbar translucent in Android 10

    Posted: 02 Jan 2020 07:41 AM PST

    So this kinda pisses me off a little bit but everytime I'm in an application, the gesture bar is present but there's also this ugly slit of a navbar which seems very out of place. Is there any way to make that transparent? I just want the gesture bar floating and no navbar

    Question: can layout_constraintHeight_percent (and similar ones) be in relation to other views, instead of the parent?

    Posted: 02 Jan 2020 06:10 AM PST

    Suppose you want to create a view that has a height of 0.5 of the ConstraintLayout, and you want to create a view that seems in it, and of 0.5 of this view in height (meaning 0.25 of the ConstraintLayout in this case).

    I tried to do this (actually quite different, but similar scenario), but it seems that layout_constraintHeight_percent (and others) are only in relation to the ConstraintLayout:

    https://i.imgur.com/YycP5EJ.png

    <View

    android:id="@+id/centerView"

    android:layout_width="match_parent"

    android:layout_height="0px"

    android:background="#33ff0000"

    app:layout_constraintBottom_toBottomOf="parent"

    app:layout_constraintHeight_percent="0.5"

    app:layout_constraintTop_toTopOf="parent" />

    <View

    android:layout_width="match_parent"

    android:layout_height="0px"

    android:background="#3300ff00"

    app:layout_constraintBottom_toBottomOf="@id/centerView"

    app:layout_constraintHeight_percent="0.5"

    app:layout_constraintTop_toTopOf="@id/centerView" />

    Is there a way to do it? Or should I really either calculate the new ratio (as one of the ConstraintLayout), or create a ConstraintLayout (or other layout) within the ConstraintLayout ?

    For now, I just use the percentage of the ConstraintLayout, but the disadvantage of it is that if I change one value, I have to remember to change the rest too.

    Tutorial for swiping away a view

    Posted: 02 Jan 2020 01:20 AM PST

    Hi all happy new year!

    Can anyone help me find a tutorial to swipe away a view but I want to be able to hold the view and stop the swipe with my finger. Lots of apps have this where you drag down and the view moves with your finger but I can't find a tutorial on how to make it.

    Thanks in advance for any help

    Thinking about creating a game guide for an existing mobile game. Is this ok or would I be infringing copyright in doing so?

    Posted: 01 Jan 2020 09:10 PM PST

    I'd have to use images of in-game assets and artwork for this so I was wondering if this would be an issue. I want to publish it at the play store but I don't plan on monetizing it, as I want to do this primarily just or fun, to showcase my work, and to contribute to the game's player community.

    Help: First time developers need guidance

    Posted: 01 Jan 2020 11:10 PM PST

    So my friend and I want to develop a social media app. Can anyone explain the general process for this, we are computer science majors so we can code but we've never done a personal project, and certainly not to this scale.

    Important Note: We aren't doing it for the money or anything we just want to have fun and make something cool.

    Developers and Designers: 2

    Budget: $50 + any costs to put app in play store

    Our biggest issue is storage... where/how do we get room to store user accounts and profiles, and conversations. Are there any cheap services? Also any other tips anyone could provide would be great!

    Edit: We know java but should we really be using Kotlin?

    Account termination ..... Still fighting the fight

    Posted: 01 Jan 2020 07:01 PM PST

    This is the latest we have sent to google:

    After month of waiting, and appealing I have yet to see any change in googles position. The one thing I have seen, apps that have copied us and our code. Since our apps where removed from google, we have seen many copy cats, in particular, craigslist apps, which was one of the apps you suspended for sexual content. That same content is in those exact apps, so I am not sure what the problem is? You have exact apps that have stolen/copied our code and are using the exact same user generated data.

    https://play.google.com/store/search?q=craigslist&c=apps&hl=en_US

    To me this is something explicitly being done and you are singling our company out.

    I still can't believe you would remove a company over night with more than 1million downloads and thousands of positive reviews.

    The app has been featured in many publications and rated very highly. One for example:

    https://www.androidauthority.com/best-craigslist-apps-940584/

    Since we have been terminated we have been doing research and reaching out to other developers on the matter and are further building out our case. Once again, I ask, that you take a look at the apps that were suspended and re-evaluate them for why you suspended them in the first place.

    It amazes me that copy cat apps that are utilizing the same data are ok, but we where removed.

    In the interim since this has been going on many more apps have come to the forefront. At this point i just want to be able to do dev work for android again.

    We have had other devs reach out for support and encouragement and we thank you for that. At this point it's just a waiting game i suppose.

    Do you experience high number of crashes in Samsung Galaxy S10 recently?

    Posted: 01 Jan 2020 06:49 PM PST

    Recently, we receive quite a number of complaints from users, and saw high number of explainable crashes from Firebase Crashlytics (The crash stack trace is hardly seen in Google Play Console)

    The is the crash trend from Samsung Galaxy S10 - https://i.imgur.com/4yioAmE.png The spike begins in the early of December. After we deliver app update code after 15 December, the spike becomes way more obvious.

    I guess the problem stars occurring in November time frame. We only start to notice this last week, since we install Firebase Crashlytics.

    I was wondering, do you have same observation in your crash report/ customer complaints too? We suspect Samsung Galaxy S10 introduces some buggy software code update recently, around November time frame.

    AdMob invalid traffic

    Posted: 01 Jan 2020 09:00 AM PST

    Google took away almost €4000 in two months of my AdMob revenue claiming invalid traffic. Never ever had I any problems with this at such a large scale. Does anyone have experience with this or does anyone know someone who can help me because this is absurd.

    Jumping back in after awhile, looking for some Kotlin assistance

    Posted: 01 Jan 2020 05:46 PM PST

    I'm working on trying to create a custom view that fills a canvas with a black screen and can then be wiped away using touch. I found an old stack overflow post that gives some good advice, but it's in Java not Kotlin. In my attempt to convert to Kotlin I'm running into an issue. Specifically, on line 34 of the Gist below I get an error that height is set to 0. I thought by adding this to only happen after onLayout would wait for the layout to expand, but I'm still getting the same error. Any insight would be appreciated.

    How do you implement SMS based 2FA?

    Posted: 01 Jan 2020 05:22 PM PST

    Hi, how are you (or would have) implementing SMS based 2FA? When user enters correct login credentials an SMS should be sent to his phone with a code, he has to enter the code and then he is finally logged in.

    How to do this?

    What's the best way to promote your app?

    Posted: 01 Jan 2020 08:59 AM PST

    Hi there, i have an app on Google Play that i released back in 2018 and i didn't implement everything i wanted or should have back then. So far (1/1/2020) the app has 30K+ downloads but only 2K active installs with the DAU hovering around 300-400. Obviously, since the app wasn't finished yet and i made the mistake of releasing it, things didn't go well as far as user retention or monetization goes (Currently, i'm making around 50 Euros/month with one Interstitial ad using Admob).

    I recently rebuilt the app from scratch( changed the UI completely, added tons of functionality, etc.) and it is now basically the app it should have been back in 2018. I haven't released the big redesign yet because i have some thoughts. Since this is my first actual app, i'm not quite sure where to begin in order to promote it and monetize it correctly. Is there a way to create ads for it on the PlayStore or through Admob? Are reddit ads a good option since my app caters to a specific gaming community here on reddit? Is Admob a viable option for monetizing my app or is there another network like it that offers higher ad filling and/or multiple ad sources*?

    What's your experience with admob monetization and app promotion? Obviously i'm a bit lost here so any advice will do. Thanks in advance

    *I know that Admob supposedly supports multiple ad sources but I've added AdColony as an ad source on Admob for a few months now but their requests are never filled and it keeps on saying optimizing which i don't know if it's intentional.

    Android Studio collapsible comments

    Posted: 01 Jan 2020 11:48 AM PST

    I know that comments are important, but now I'm trying to learn from google developer codelabs and their sample code has copyright comments at the beginning of every file. Is there any method to automatically have those comments collapsed by the IDE?
