[REQUEST] Magisk Module to Disable Flags Secure

[edzamber]

Hi,

I wonder if someone can do a module to enable Screenshot in protected apps as Disable Flags secure Xposed module can do...

Hi,

First thanks for your reply[emoji2]

It seems that modifications by xposed module are in framework.jar, especially into WindowManager.LayoutParams.smali and into SurfaceView.smali

Thoses are define by setFlag methods

Here are some links about how it working

Ok, so its call an special function in framework.jar file system so it could be possible but the problem is that we must import all possible framework apks in the Magisk Module zip, without taking the fact that if anyone want to make it works with any other stuff that modded the frameworkres.apk, we will must add again all the apks..

One more time, we can see again the big differencies between Magisk and XPosed..
With Magiks, we can say to the Magiks framework to create several symbolics links to everywhere u want without edit any files.
With XPosed, we can say to the Magisk Framework to add and/or replace and/or deleting one or several JAVA method(s)/function(s) into the android core system without having to decompiling, editing and compiling again the apk(s).

In absolute, we could make this Magisk Module, but we will must try all possible frameworkres apk file(s) with all possible other MODs stuff that could working fine on all phones and ROMs versions, so finally the Magisk zip could make less than 1Mb if u have a great chance, or it will make more than 100Mb.

Ok i understand !

I upload my framework.jar, it can be a good beginning [emoji2]

I think there will be a lot of request for this module as many people on many different device are looking for disable flag_secure [emoji2]

You could take a look at the work by @fOmey with his Mock locations patcher (patches services.jar) and see if there's anything there that might inspire you...

If you guys can figure out what is being patched by xposed, I'll have a poke around and convert the xposed to a smali solution..

I have the patcher already coded, so it wouldn't be overly difficult to adapt it to this module idea.. just be sure to tag me in the post.


EDIT: Bit bored at work so I had a poke around..

Pretty sure I found the function you want to patch, won't know till you test: function

The fun part is finding it in smali and making sure its consistent between different device manufactures ...

Waouu !!! Working [emoji2] [emoji2] [emoji2] [emoji2] [emoji2]


I mod directly my services.jar like this :


Services.jar/smali/com/android/server/wm/WindowManagerService.smali

.method isSecureLocked(Lcom/android/server/wm/WindowStateZ

Replace complet method by this :

.method isSecureLocked(Lcom/android/server/wm/WindowStateZ
.locals 4

const/4 v0, 0x0


return v0
.end method

Now just need to apply this with Magisk module, but i don't know how to [emoji2]

Good to hear! The tricky part also is most devices have unique services.jar's... this is why I created my patching tool..

If I get some time over the weekend I will look into creating a patcher for this module.

Can you help me to understand if this is possible to do to an APK? I'm using an Oculus Go, and they made it so we cannot screen cast in the Oculus TV app, so I am trying to see if it's possible to remove the FLAG_SECURE from the Oculus TV app. Any help is greatly appreciated!
