{Problem} Running old apk on recent Android versions - Android Q&A, Help & Troubleshooting

Hi everyone!
I'm facing a "big little" problem with an custom made Android app. I don't have code skills so I don't know how to change the code of the appk.
The problem is something like this:
- Have an apk created a few years ago, with the API level 19 (android 4.4). It runs okay at all Android 4, 5 and 6 versions, but since android 7 I can't use it. Is an application that need root privileges to work properly.
There are any simple way to do something that allow me to run that apk on Android <=7 version?
Can't downgrade Android version because the stock version of my actual android phone is the 7.1, can't go lower than that.
Sorry if my question is not well explained, my English is not too great.
Thanks
Cheers.

Don't worry , your English is understandable
I don't think you can run older APK on a newer Android version. Because the API used in this app may be deprecated or something like that.
I'm not sure of the info I provided you here so if someone tell you the opposite , he may be right .

Is it possible to patch pokemon go to work on 4.3. Jelly Bean? Or get a beta version?

Hi Guys,
I really looked forward to playing Pokemon Go and was really shocked when i saw that the release version of it supports just android 4.4. kitkat and onwards but no older versions. My phone is stuck on 4.3 jellybean and cant be rooted so im sitting here sadly now I already managed to get the app installed by using Gmaps patcher, it also starts but won`t let me sign in via google or pokemon club. So now im asking you guys at xda, who are the most amazing guys in android scene, is there ANY possibility to make it work on android 4.3 jelly bean? The fact that it was planned for 4.3. in the beginning and beta testers claimed it would work on that version leaves me with al glance of hope.
Here are some ideas i have as a noob:
Since its possible to install the game and make it run, but just signing in wont work i guess the app is not far from running on 4.3. On top of that the games developer and beta testers claimed it working on 4.3 and onwards. So i guess in early stages it already WAS running on 4.3. Maybe it can be patched or modified in a way that it will work? If so, is anybody willing to work on that proect? Im affraid me as a noob is no option.
The Fact that beta testers and the developer said it would work on 4.3 might mean that an older version or beta version would run on 4.3.? Is there anybody who has a old/beta/field test version to test that?
Is there any other option? Or is it complete hopeless? Please try to help me, i was waiting for this great game so long and now i cant pay it, while all my friends do

I would love to do that but since i have a blackberry phone its completely locked as far as i know. I someone has other infos regarding that, please tell me
Ah that sucks. I think there are some apps that where being back portet. If it's viable to Pokémon go too i dont know through.
You could buy a cheap as android Phone with android 5.0
For example ZTE blade l3 it should be around ~80 to 90 bucks, if you can afford that much

Thank you for our answer. Maybe someone knows if this gets packported maybe? Im sure lots of people would appreciate much.
You can dowload 0.13.5 version.that work.
you can't install apk files that uses higher API level (Pokemon GO, 19) on older Android version (Jelly Bean, 16). It's like trying to use a remote tv controller like a cellphone, you're trying to use a function that your system doesn't have. i don't think a generic patcher can solve this and i don't know where you found that apk, but you should be careful of what you install on your device. Anyway, out of curiosity i checked for you, given the possibility that for some "strange" reason Niantic decided to set the minimum sdk level to 19 without really use any functions that is not supported in Jelly Bean (whaaa? so why use higher API level than? maybe cause if you are running on KitKat you are 90% running on a "new" device, this is faster than making a list of hundreds of compatible phones). Worst case scenario is that you will get a NoClassDef exception (probably) and of course app crash.
(the following is not a piracy attemp, we are not trying to hack anything. it's intended for learning purpose and to satisfy your curiosity)
ok, let's start :
so, you need to set minimum sdk to Jelly Bean level (16)
to do this , you will need to edit the AndroidManifest.xml file, inside the apk, adding this line
("<uses-sdk android:minSdkVersion="16">)
and of course deleting any labels or parameters that are not recognized by 16 API level (in Pokemon Go case : things like android :isGame, android : banner, etc..)
(oh..but you can't just edit the manifest inside the apk, that is compiled. you need to decompile it first)
even if doing this doesn't break the app (very improbable) now you need to recompile it again (just for obtain a new compiled manifest file, that you can inject in the original app using Winrar/Winzip..infact .apk are just jar/zip files).
of course, we can always just edit the compiled manifest, just need to be able to read, unreadble anti human characters.
so, now it's "working" on android 4.1 , but can't get past splash screen, hangs after that
stuck at -- E/dalvikvm(32567): dlopen("libNianticLabsPlugin.so") failed: Cannot load library: load_library(linker.cpp:750): library "libNianticLabsPlugin.so" not found --

i don't think you should distribute a modded apk, even if it's free
anyway i'm really curious, can you tell me what you did? i'm hitting a roadblock
oo
Could we go the other direction? Is it possible to install the required libraries that 4.1/4.3 is missing and fake the system version to Pokemon Go?
Mine wont install at all on 4.3

Does it? Will it work in North America, and can you change the language to English? From what I've seen, this is the Japanese beta release.
A trustworthy download link would be nice as well, as there are some fishy apk's floating around.
I have a Galaxy Stardust S766C (a tracphone) with Jellybean 4.3. Any chance in hell that mod will work for me?

actually, Pokemon Go can be installed on Android 4.1. it hangs after the splashscreen because it can't "see" some .so files (even if they are inside lib folder). it seems to be cause of a different behaviour of dlopen on different Android platforms.
i'm trying to get a list of dependences for that libray and see if it can be workarounded

If you managed to get this working, you would be an absolute hero.
The same ZeonZs, ZTE Blade Q with android 4.2.2 and a black screen...
Good luck Jumpersize, we count on you !! :good:

ZTE Z233v Question

I have noticed that this device runs a spin-off version of android 5 but has a lot of things disabled. How can I enable developer mode on the phone. It is a flip phone running a android os but you can not seems to enable the developer mode by the usual method. It also does not seem to have the full version of android but somebody had told me possibly Cintrine OS since it is a ZTE. What file extension does this thing use? Is it even possible to install apps and the full android OS on it?

I am glad someone asking questions regarding this phone. I am also searching source code of kernel and Launcher - did you find it ?
But yes, this phone based on Android and can launch apk files inside. But it is cut version

Is it possible to see when an android phone downloaded an certain patch?

Hi,
I dont really know how to start a thread so i get right into my question.
Is there any way i can find out when my phone downloaded android 9? I know that you can go to settings and look when your phone downloaded the last patch but i would like to know when my phone downloaded android 9.0.
Thanks for all answers and i apologize for my bad english its not my native language.
@Habicht99
in system file named build.prop you can find date when the current ROM was compiled
ro.build.date=Sun Feb 22 04:00:49 UTC 2015

Thanks for your answer.
Since im not very into things like that i would like to know if i really understood you right. At the moment im on android 9.1.0 if i would look in build.prop would it show me the date when 9.1.0 was compiled or the date when 9.0.0 was compiled?
@Habicht99
I clearly said "current ROM":
Android ROM refers to a phone’s firmware - it actually may be the (original) Stock ROM or a Custom ROM. If phone's Stock ROM got upgraded and/or updated and/or replaced, then the question "Who compiled and when was compiled the phone's Stock ROM" you have to ask phone's manufacturer and/or carrier, IMO.
Also: Moving from Android 9.0.0 to Android 9.1.0 - as version numbers show - is an update , not a patch.
AFAIK an Android 9.1.0 never got released by Google, but an EMUI 9.1 ( Huawei ) exists.

ALPS H960 10 inch tablet

I purchased a ALPS H960 tablet and it doesn't attach to 5G WiFi but the two apps I have install that display the phone/tablet information says it should. I believe it is the same as MT6797 or Pavoma G5. From the research I have done it is running a hacked Android version 9. Would it be possible to root it and flash it to Android 10 or 11 to get to work on WiFi 5G if it can't be changed the way it is now? Thanks.
Were you ever able to fund a way to root this device? I have the same one and wanted to do the same thing.
