| What do you love and hate about Android development? Posted: 28 Dec 2020 01:41 PM PST I've recently started dabbling with Android in a pretty serious way and it's also my first experience with mobile development in general. Since it's the end of the year, name at least one thing that makes you really happy about the current state of the ecosystem and at least one that you despise deeply, including your motivations. What I like:
What I don't like:

| Posted: 29 Dec 2020 03:46 AM PST I can see the SSL pinning of any android application is tampered by reserve engineering or by using any rooted android deivce. How do i make sure the android application can never be tampered . Is there any strong SSL pinning which can be implimented so none of the hackers who try to bypass the ssl pinnig dont work ?

| How to prevent fragment recreation in navigation component? Posted: 29 Dec 2020 09:07 AM PST I'm new to android development, so please be as in depth as possible(even if it's external reference), there are probably a lot of things I'm not familiar with yet. I have recycler view with animal classes (let's call it fragment A). On item click, the user gets redirected to fragment B, that's another recycler view, each element is card with animals of that class and some info. The problem - if user scrolls in fragment B, goes back to fragment A(this one keeps its position properly) with back button, and then clicks again on the same animal class, the fragment B will be recreated and position of recycler view is reset. So how do I keep fragment B in backstack ? Btw I'm using kotlin, so if possible don't explain/give references in java. [link] [comments] | ||
| Attach Debugger to App started using am -D? Posted: 29 Dec 2020 08:47 AM PST Hi, I want to debug an installed app (nothing I have written) which crashes on startup. I managed to start the app using am -D via adb, so that it waits for debugger to attach. I can then attach gdbserver to the pid and connect to that via gdbclient and catch the signal. However, it is only missing now to actually start the execution of the app by attaching some debugger (which will not be used, but just so the execution is started). Any hints on how to achieve this? Thanks! [link] [comments] | ||

| Is it possible to replace old apk with the new one in playstore console? Posted: 29 Dec 2020 07:35 AM PST I've generated a new apk using third party addon for my website. The old developer i hired is no longer responding, so is it still possible to replace old app if I have just the user ID and pass for playstore console, without loosing downloads count and positive reviews?

| Can you list UI skills you need to work as a dev? Posted: 29 Dec 2020 05:47 AM PST I've been learning Kotlin for the past 6 months and I'm not very interesting in UI design but I get that having to know how to work with it is something you need to know to get a job or for your own projects too. I guess you're gonna mention Constraintlayout but specifically, which are the basics functionalities you need to know? [link] [comments] | ||
| Is there a way to intercept SMS messages sent by apps? Posted: 28 Dec 2020 09:48 PM PST Hello everyone. I'm not sure where to turn to, but for the past couple months i keep getting charged in my bill for SMS messages abroad that i never sent. Looking at the detailed bill they get sent to random numbers in France, Morroco and other random countries. They never show up in my SMS app. Looking at the permissions, no app other than the default SMS app should be able to send messages. I am completely lost on how to stop this or how to even begin looking for whats sending them. [link] [comments] | ||
| How to identify/stop user from availing subscription on multiple devices Posted: 29 Dec 2020 05:07 AM PST Hey, I want to know about the Google Play IAP Library tackling the issue of multiple devices added to the same account. I own an app and want to provide a subscription but the only problem I am facing right now is what if the user logs into 10s of other devices with the same Google ID he/she purchased the product with. Can you please explain to me something in this regard? Thank You [link] [comments] | ||

Posted: 29 Dec 2020 02:51 AM PST If i have a 4.4 rating of my game in english language then what rating will be in Spanish language? It will be same or different? For example below mentioned game has 4.4 rating in english language, i am wondering what will be rating in other languages? I randomly picked this game from play store. [link] [comments] | ||
| Why is there are so much boilerplate code? Posted: 29 Dec 2020 02:42 AM PST Hi, i'm a begginer to android develoment coming from web development. I started learning RecyclerView and Retrofit(for consmuning rest API's) and i'm overwhelmed by the amount of code that needs to be written for the above two functionalities. Is every simple functionalities going to need a bunch of classes and interfaces for implementing or are these two are just outliers? [link] [comments] | ||
| Running other apps inside your own app!!! How are they doing this?? Posted: 29 Dec 2020 12:54 AM PST I've searched high and low and I can't seem to find any hints on how something like this is possible. The AR glasses NReal has an app called Nebula that runs already installed 2D apps on your phone and display it as 3D dockable screen in your virtual room. Here's an example Honestly up to this point I wasn't even aware something like this is possible, but I can't seem to find any clues on how it works. [link] [comments] | ||

I have read everything online where I must be missing something somewhere somehow. S10e, snapdragon, SM-G970U Flashing stock rom for SM-970U1 [link] [comments] | ||
| Real life use cases of ordered broadcasts Posted: 28 Dec 2020 11:54 AM PST Hello! Does anyone know of authentic scenarios where it would be useful to use ordered broadcasts in an Android app? I have found these two examples: Android Developers Blog: Processing Ordered Broadcasts (googleblog.com) for phone call redirect apps and GitHub - kevinthecity/OrderedBroadcastExample: Demo project illustrating how to use an ordered broadcast for handling notifications differently if the app is in the foreground. Outside of these, do you know any other useful use cases? I am asking for my final year project for my computer science degree where I am exploring vulnerabilities related to Inter Component Communication, so examples that are no longer good practice are still good for me.

| What's the difference between Freezing, Disabling and Hibernating Posted: 28 Dec 2020 10:22 AM PST Hi, I wonder what's the difference between Freezing, Disabling and Hibernating android apps. For Freezing : Superfreezz and LuckyPatcher apps do that. For Hibernating : Greenify does that. For Disabling, It can be done via Settings. [link] [comments] | ||
| Posted: 28 Dec 2020 05:25 PM PST Hi everyone, i'm trying to do a simple "barber app" with android studio/firebase but i don't think to be on the right road... My goal is "make an android/ios app with: A form (login/signup), a homepage with news,coupons ecc.. places by the admin/owner and an appointment feature (with notification)<--not necessary. I'm asking at all of you is it the right way? And the easily? Or i must change way to perform my app? Any hint will be helpful, thanks in advance. [link] [comments] | ||
| Guide to release an app (Google to play store) Posted: 28 Dec 2020 02:14 PM PST Anyone knows a good guide, what I need to do to release an app I have developed? I know I need a developer account to do so, but what else? There is stuff like DSGVO in my country, privacy policies and idk what else, I need to care. How do you handle stuff like that? Is this even necessary if I just have all my data locally on the smart phone, i.e. a local database? I also know some apps allow to sync/export/import/backup there local data to the cloud, who has to deal with those DSGVO and privacy stuff here? What if I import my data always from the cloud/an other app or service? When I got a new phone I also restored all my apps from my old phone using googles backup. I realized, that some apps were completly empty, while others had the same data as the apps on my old phone, so some apps seem to backup their data using googles system backup? Who has to deal with those privacy/DSGVO stuff here? Are there more pitfalls to release my first app? [link] [comments] |
