convert android to ios app - Android Q&A, Help & Troubleshooting

Hi all,
I made an Android app using firebase as database and login provider, and I want to make it available on iOS! I used mechdome for this and it worked! But not completely.. the key thing doesn't work and that's firebase. Is there any tool that supports it?

Help Developing Android app in Android Studio!

I'm a 14 year old android app developer in training
I need help/tips on my app. I have already set up android studio with the sdk and jdk.
I already made the wireframes and storyboard of the app. So I started making the main screen/activity in Android studio. Done with the main screen, although I haven't programmed it yet. What now? Do I start another Activity? I would like for you guys to help me through the process of developing my android app. It's called Shadow. I would really appreciate the help from the adult Developers.

Post a screenshot of your app. What kind of app you are trying to develop.. give a brief description as well.

Hi !
If you want to do several "pages" with different controls there are several ways:
1 . use different activities . This is the simplest way
2. use fragments. This is a bit more difficult
What do you mean? Screenshot of my wire-frames? or of the main activity app?
The app I'm developing is a File hider App. But it's a little more organized and clean/minimalist looking than the other apps that are on the market. I call it Shadow File Hider. You're supposed to select the files that you want to hide and place them in a list. You can activate that list with a switch. The files are hidden. To show them again, just use the switch. But I also want to incorporate a way of hiding the actual app. This is what will make it stand out from the other apps. You can use the pattern lock screen as a Boss Key to hide the app. Use a custom pattern - that you set up in the app - to activate the app, before your normal pattern. That way when you use your smartphone normally no one will know the app is there or that you are hiding something. But you can easily open the app and close at will.
BTW
What's the best way to monetize my app when I'm finished?

So I'm on my way to finishing the app. But one of the main settings in my app is to hide itself with a boss key. It's supposed to work with the lock-screen pattern. But how am I supposed to develop that? Any Ideas?

Need help with updating an apk

Hey all,
There's an app I need help updating to either api 24/26 . The app which is meant to interface with the Joyetech Ocular/Ocular C, which is on Google Play,
https://play.google.com/store/apps/details?id=com.zijing.joyetech
The problem is, the devs of the app hasn't updated it since api 22, and after sending emails to the devs on multiple channels, there's no response.
Looking at the logcat of an app's activity, the Android app derives keys using the SHA1PRNG algorithm from the Crypto provider, and as of Android N, apps must start using a real key derivation function.
My issue is that:
1: I'm very mediocre at things like this. (Decompile, import into Eclipse, edit as needed, then recompile.)
2: My laptop doesn't have enough space to install Eclipse.
Would anyone with more knowledge on this subject be willing to update this apk for me?

Keep OTP App when upgrading system

I have a monthly appointment to update my LineageOS phones. However, the time has come to upgrade the major version, which means manually overwriting system. But one of my phones has an OTP app (FreeOTP) that I use for Two-Factor authentication. I need to know if that app will continue to work if I back it up using Titanium. Part of me has this feeling that it uses something unique to this OS in order to generate the codes. And since several sites are dependent on TFA, that would leave me in a very bad place.
So, anybody knows how I can safely upgrade my phone without losing access to the OTP generator?
FreeOTP+ (a.k.a. FreeOTPPlus) has backup/import/export capabilities. Migrating is a cinch:

API Issue

Hi All,
I've encountered the following problem:
I built an app that uses weather API. When I launch it from the android studio on an emulator or physical it runs excellently, data is fetched. However, when I published it on Google Play store and download it from there, app is not able to do any network calls (no data is fetched).
Any suggestions on what am I missing, please?
