Hi All,
I don't have experience developing for Android but I'm exploring a few ideas and I'd like your expert opinion and support.
Do I have to run the entire OS stack on an Android device or it can be broken up? for example, run the essentials like Kernel, HAL, some native libraries and stream the rest from a central cloud?
the goal is to create a thin device with essential functions like voice/sms and stream the rest of the OS functions.

I'm looking for a non-system keyboard for Android systems analogous to the Java class provided by Vladimir Petrenko ca 2017.
Such a class provides a graphic keyboard which enters characters in a text field via the JTextComponent.getCaretPosition()/setText() methods. Input characters do NOT go through the key-loggable key interface.
Hopefully, someone interested in avoiding keyloggers will already have such software for Android.
Found none, thanks.

Long story short, APK Installation is blocked on LG Classic Flip (no, it's not in settings). There is a way around it though: Decompile an APK, Go to androidmanifest.xml, change package name from com.example to com.android.cts.example (cts stands for compatibility test suite). It works beautifully for most apps, but some apps like Whatsapp are very protected and crash when I do that. Is there a way around that? Same with spotify.
On a side note, some apps aren't sized right for LG Classic Flip (Flip phone). LG Classic is 320x240 pixels. Is there a way to resize the apps (and not the screen).
I'm new, and I am not an expert, so please explain in beginner terms if you have the answer to either of these questions. I'm not stupid, and I learn very quick, I just am not very knowledgeable in this area. Thanks for your help in advance!, Shlomo Rabinowitz.

Hello,
first of all I apologize in advance for my mistakes, but not being at ease with the English language I prefer to use a translator.
I just rooted this tablet with TWRP & Magisk.
Now I want to change some features in the settings menu.
For example, I want to prevent the user to delete an application.
I tried app locker to block for example termux but unfortunately you can still delete the desired application. Of course, app locker can't be deleted but the applications it protects can.
on the other hand, is it possible for example to switch the tablet to airplane mode from 9 PM and to grey out the functionality to avoid that the person reactivates the connections ?
Sorry this is a lot to ask but if you can help me it would be nice.
thank you and good day to all
