    Call/SMS - filling out the Permissions Declaration Form for an SMS scheduling app (for non-English speaking devs)

    Posted: 13 Feb 2019 12:30 PM PST

    EDIT: some have asked why the developer is not claiming the "Device Automation" exception. That is a good question - I think he has already been rejected for that, so this time he is taking a new tack, and asking for a new exception type (if Device Automation is not working he figured, he should try something else - like "Scheduler App" type of exception). I have just suggested text for the screenshots I was provided (which I admit I was confused about myself - but since the Form changes all the time I assumed it was a newer iteration). The question remains whether the developer would be better served continuing to re-request on the same "Device Automation" exception (and being rejected again and again), or to try the new exception type route.

    Difficulties for non-English speakers

    The Permission Declaration Form is a hurdle for English speaking developers. They can make the distinction between what the Form claims, and the unreliability of the Google response to it (exceptions which Form says can be requested are never granted with a terse bot-generated e-mail).

    This process is worse for non-English speaking developers - when this happens to them, they wonder if their understanding of the Form was at fault.

    To be fair to Google, while their Permissions Declaration Form does not mention other languages: https://support.google.com/googleplay/android-developer/answer/9047303?hl=en

    In contrast to that, the Permissions Appeal Form does mention some: https://support.google.com/googleplay/android-developer/contact/permissions

    Note: We can only respond to appeals in Chinese, English, Japanese, or Korean at this time.

    A non-English speaking developer asked for suggestions for what to write in the explanation boxes on the Form.

    I provide a snapshot of what the Form looks like, and an example of how it could be filled - for a (highly rated) SMS scheduler app.

    It may be illustrative for non-English speakers. Developers can suggest improvements or alternate exceptions which could be claimed instead of Device Automation.

    The app is an SMS scheduling app (highly rated). The SMS is completely driven by the user - they compose the text of the SMS, and they set the time. So when the SMS sending is triggered later, it is completely with user's prior consent.

    Here are the screenshots of the Permissions Declaration Form that the developer provided:

    Individual images:

    Here is my understanding of how a developer might respond to the question on the Form.

    Choose the appropriate advance notice scenario:

    New use case of accessing SMS/Call ...

    Use case:

    Users automate the sending of SMS messages by scheduling the sending of an SMS message at a future user-specified time.

    If there is more space, you can use this longer sentence:

    Users automate the sending of SMS messages by scheduling the sending of an SMS message at a future user-specified time, which is why we are claiming exception under Device Automation.

    Required permissions:

    [x] WRITE_SMS SEND_SMS

    Describe why the use of sensitive permissions is necessary for this use case:

    Since this is an automation app which sends a user-crafted SMS at a user-specified future time (without further user intervention/clicking of dialog boxes), the app needs to use READ_SMS permission (the alternative of using SMS APIs will require user click a dialog box at future time, which will kill the functionality of the app).

    Is your app's use of Call Log or SMS permissions to provide functionality required by law or regulation ?

    Yes

    No - check this (since I assume you are not providing this functionality to fulfil some law or regulation)

    If portions of your app are restricted to logged in users ...

    The functionality described can be tested by all users (does not need special sign in).

    NOTE: I assume here that when users first start app, they can schedule an SMS, and set it to send at a later time etc. - and don't need a special account - if it does, provide that account info

    If portions of your app are restricted, please upload link(s) to any screenshots or videos of your app to help verify the functionalities and use cases declared above.

    The functionality described above is not restricted. However, I am providing a video link which describes the scheduling of a test SMS message, and it's eventual delivery at a later time.

    NOTE: If you can make a video, make one where you compose a message, and schedule it for later time .. then video should cut i.e. jump immediately to showing how that SMS is sent (if a notification appears or some indication appears - you may want to show that in video with a circle or something. You may also want to show an overlay at the top which shows the time let's say 10:00am and then when video jumps to 11:00am when the SMS is being triggered/sent out). If you can't make a video, you may want to make a series of photo slides and make that into a video perhaps. If you want to say something you can put it as a subtitle in the video.

    EDIT: Any screen recording app available on Google Play store can be used to record the session.

    Running closed beta test in play store for premium game without risk of APK being spread

    Posted: 13 Feb 2019 12:21 PM PST

    Hi,

    We will soon run an closed test round on Google Play with for us, unknown persons. The game will contain a free part and the option to buy the full game, but for the testers we want to release a version where the entire game is free. The risk is then that the apk will get spread. How have you handled this scenario?

    Have you set an expiry date/self destruct date?

    Another option would be to run the test with the pay-version and give away some of our free promotion codes to the tester.

    How do I move a view upwards using the ObjectAnimator?

    Posted: 13 Feb 2019 12:07 PM PST

    textView.animate().translationY(500).setDuration(3000);

    This is a pretty simple line of code that moves my view downwards, however I cant seem to find out how to move it upwards. No one seems to be asking this question so I thought it would be a good idea to ask here.

    How much attention do you pay on Android Lint?

    Posted: 13 Feb 2019 09:16 AM PST

    How much attention do you give to lint error checking?

    I just run check on my main app and too many warnings showed up, but most of them were trivial warnings that are not worth the time in my opinion.

    What about you? Do you care about lint? Are your projects lint error and warning free?

    Play Store Optimization Tips tablet

    Posted: 13 Feb 2019 11:55 AM PST

    Hello all 👋

    I am wondering why one of our apps get a warning/error in the Play Store Console > User acquisition > Optimization tips section.

    Your Production APK needs to meet the following criteria: Your APK should include custom drawables assets for common tablet screen densities.

    Everything is done for tablet on this app, vector drawable, constraint layout, dedicated layout for large screens etc. The few bitmap drawable used are provided in multiple densities.

    I checked their guidelines and explanations and nothing seems wrong to me. I've even added the <supports-screens /> item in the AndroidManifest.xml to indicate the app supports large & xlarge screens.

    On 2 others apps, one of them very similar in terms of assets do not get this warning.

    Do you have any input on that?

    Can we use Admob in AOSP devices?

    Posted: 13 Feb 2019 10:42 AM PST

    I make apps for an AOSP based Android TV device. The app is not distributed through playstore. It comes pre installed in the TV.

    Can I use Admob, Mopub or any other ad network to earn money in my app? Will it violate their policy? Is there any other ad network that I can use?

    Live Translation?

    Posted: 13 Feb 2019 02:11 PM PST

    Hello devs. I was wondering if someeone could help me out with an inquiry. I recently tried LiveTranscribe from Google and fell in love with its capabilities. I know Google Translate has a 'push button/take turns' option for translation, but I would love to have something thats real time like Live Transcribe, but in a window underneath it translates as the person is talking.

    My question is, does something like this exist already? I have not found anything in my search. OR Is it terribly hard to decompile the APK and just code a translation part/window mode for what I'm seeking?

    Is there a way to view which admob ad ID is being called in an app?

    Posted: 13 Feb 2019 10:43 AM PST

    I'm trying to do a little detective work on an app in google play. I can't click the ad, but I'm trying to figure out which ad ID the ad has. It's a long story...

    But anyway, is there a way to view logs while the app is loading the ad or something?

    Replacing Recycler View with another Recycler View on item click

    Posted: 13 Feb 2019 04:23 PM PST

    When the user selects an item in my initial Recycler view A, I want it so the entire Recycler view is replaced with, lets say Recycler view B. I know I'm suppose to type my code in the onBindViewHolder method, but I'm not sure how I would apply this.

    Does Samsung Galaxy S9 and Pixel 2 return an installer package name when downloaded from Google Play Store?

    Posted: 13 Feb 2019 09:00 AM PST

    Does Samsung Galaxy S9 and Pixel 2 return an installer package name when downloaded from Google Play Store?

    I implemented some mechanisms in my app to make it as difficult as possible for people to steal and crack it. One of these mechanisms is to check, if the app was downloaded from Google Play Store:

    public void checkInstalledFromGooglePlay()
    {
    final String vending = "com.android.vending"; //Play Store
    final String feedback = "com.google.android.feedback"; //Play Store
    final String installerPackageName = context.getPackageManager().getInstallerPackageName(context.getPackageName());
    if (!vending.equals(installerPackageName) && !feedback.equals(installerPackageName))
    {
    ACRA.getErrorReporter().putCustomData(SecurityUtil.class.getSimpleName(), "Not installed by Google Play");
    ACRA.getErrorReporter().handleException(new MyException("Not installed by Google Play"));
    throw new RuntimeException("Installer package name not found: " + installerPackageName);
    }
    }

    This basically works.

    But I saw in Pre-Launch-Report in Google Play Developer Console that this mechanism does not seem to work with Samsung Galaxy S9 Android 8 and Pixel 2 Android 9. The report shows me, that these devices seem to return null.

    ​

    https://i.redd.it/y6s08vsy9dg21.png

    This either means that these devices happy some buggy Android implementation (I would not be surprised with Samsung since Samsung always has a lot of tinker crap inside, but not with Pixel 2), or that this Pre-Launch-Report mechanism does not "really download from Google Play", but it works with all the other 7 of 9 devices, so I assume that this really does not work with Samsung Galaxy S9 Android 8 and Pixel 2 Android 9. (When null is returned, it usually means that the app is not downloaded from Google Play Store.)I'd like to ask, if someone implemented something similar and can confirm that this works with a "real" Samsung Galaxy S9 Android 8 device?I know that it works with a Samsung A3 Android 8, but this means nothing.

    I'm appreciating any feedback or suggestion that can boost or improve my resume.

    I know about r/resumes but I decided to post here because I suppose you are more relevant in giving me feedback regarding the content. Although any feedback is welcomed :)

    How to unsubsribe from Observable in onPause, then resubscribe in onResume?

    Posted: 13 Feb 2019 02:03 PM PST

    Hello, I am feel really stuck. Basically I have such problem. I create network request and after that I create an Observable which would trigger same network request every 10 seconds. I add that Observable to disposables and clear in inside of Activity( I can't create it inside of ViewModel, because I need lifecycle states). Then I must to stop that Observable, which creates network requests, if onPause is triggered.

    This is because, I recently figured out, that if user uses battery saver, then all network requests started from background will be killed and SocketException will occur... This fact really changed my logic and will impact my code. Right now I don't know how can I clear that disposable smartly, because I can't simply call clear() inside of onPause, if response from that Observable does not satisfy particular condition.

    ​

    So, I should clear() that observable, check inside of onResume if condition is still not fulfilled and create another observable, which would do same work, fire request every 10 seconds. It does however looks like a mess.. I need clean solution. I tried without Rx, but handlers worked unpredictably and even worse...
