Getting around signature verification (I think) on Stadia - Android Q&A, Help & Troubleshooting

I've recently made an adjustment to the Stadia APK to allow use on data. I've installed my patched version of the APK, but I need help with getting around the signature verification on the login. I'm pretty sure this is the reason I can't login but I can't seem to find anything in the code for it. If someone could please help me find the Java code in the classes.dex for this, it would be very helpful so I can continue work on modding the APK and so I can test my changes.
Thanks!

The modding for the Stadia APK is mostly for fun as a side project so sadly I can't afford to pay.

How to install multiple instances of the same .apk

I was tinkering and editing an apk, and i managed to compile it and install it fine and it works and is suited to me. So i was wondering ( not too good with xmls ), is it possible to edit the manifest file to rename the apk so I can install multiple copies ( i.e. have the original unmodified one and the modified one at the same time ). I need this for testing purposes. Which lines do i need to edit exactly so the phone doesn't give me the "installing this application will replace the current..." warning, so I can multiple instances of it?
Hope I'm being clear on what exactly I need, any help is appreciated. Cheers
Edit : Just found a post from this guy on a simillar thread that i couldn't find using search

It is not a simple matter.
APKs are managed by package name, not by file name, but you can't simply change the package name in the manifest of a compiled APK.
Even assuming you manage to do it without messing up the file, which is not a simple task, there will still be code referring to the package name, so the app will crash.

So is this true ?
Yes it is, I've tried.

Moving to Q&A
Yeah. Even if you could modify the package name, there could be hardcoded references to this application's intents within the source, which could cause problems when you realise you'll have to also change all of the intent-filters as well.
Its probably more trouble than its worth, as you'll be spending most of your time working out bugs introduced by your editing the APK.
I know its not exactly what you're after but why not try to run the modified app in the emulator on ur computer?

Yeah, thought so myself. Used the emu for a while, but It's so damn slow, can't compare it to actual testing. Nvm, I've dropped the matter anyway. Thanks for the reply

Change the package name in code and associated files with it, and then compile and execute the apk, sign it and then try to publish.
via Phone
I know that but there is so many files associated with it. It would take forever to do so!
Thanks for making the effort to help though.:good:

[Q] Edit .apk wirh winRAR possible?

Hey guys,
I was searching for a tool to edit an apk file and i found Apk Tool on xda but i think it's not
that much easy to work with this program. (for a n00b, like me.. )
I managed to open and edit te file with winRAR,
but is this program also capable of proper compiling the app again, ready to use?
I tried it and it worked well i think, but is this possible with any app or other kinds of changes?
If this is stupid or something, please tell me. I am not very experienced in these kinds of things.. (neither in english, sorry.. )
Somebody any ideas?
Thanks in advance!

It all depends on what you edit,obviously you didnt make a fatal change,so it must have been small,no its not possible to edit anything else as far as the manifest and xml files.You'll get a parsing error.

Okay, that's true i only changed those kinds of files and it wasn't a problem yet.
I changed somethings in an demo version of an app and now it recognizes it as the full version so winRAR can be pretty usefull for apk edit if you keep things simple like this..

From the way you worded it it sounds more like you have a decompiled apk, not the source code for the apk. Depending on what you want to edit you may need the actual source code to make the changes. What are you trying to do?

What you are trying to do is considered cracking an app which makes it warez. This is banned on this site. You will find no help doing what you want. As for decompiling and recompiling an apk there are tut all over the site. Search and you fill find what you need. But take this as your warning. Asking for help cracking the app will get you banned. Take this as your only warning.

Zwift APK - re-sign or mod? - Compatibility Android TV

Hi all,
I was wondering if anybody could assist with helping make an APK work on Android TV.
Zwift is the app - it's a VR Cycling and Running app.
I have the latest version of the APK to sideload -- Unfortunately it's not signed to work with Android TV yet, so it comes up with the error "app not installed"
Does anybody know a workaround?
I'm not sure which parts of the APK to modify or how, other than re-signing. I've search online high and low.
Help is greatly appreciated. I can attach the APK if required.
Thanks

No you can't modify the apk for that....the frame jar is what is responsible for detaching signatures....

Okay.
Am I correct in a assuming that the APK isn't signed for Android TV? - with the "app not installed" error msg when trying to install the APK.
What if it's something else other than whether or not the APK is signed that may be causing this? Perhaps it could be something resolvable without root?
I need to get this apk installed on the Sony Bravia so I'll do whatever is requred, if rooting turns out to be the only way then I'll do that.
