heheheheh

Kaz Wolfe

also, remember. IWindowManager is an interface. It carries no code by itself.

TheWanderer

yeah I actually need to get this:

IWindowManager.Stub.asInterface(ServiceManager.checkService(
                        Context.WINDOW_SERVICE));

Kaz Wolfe

Wait, doesn't that return an object that already exists?

TheWanderer

maybe idk

because I can't find the source anywhere

Kaz Wolfe

Well, if it returns an object, you can just call setForced... on that object directly.

TheWanderer

23:02

pretty sure the object is IWindowManager

Kaz Wolfe

no, it'll be something that implements IWindowManager so it'll work.

TheWanderer

private IWindowManager mWm;
mWm = IWindowManager.Stub.asInterface(ServiceManager.checkService(
                    Context.WINDOW_SERVICE));

so yeah

Kaz Wolfe

there you go

TheWanderer

IWindowManager implements IWindowManager?

Kaz Wolfe

no.

TheWanderer

23:03

Kaz Wolfe

That method returns an object that implements IWindowManager.

TheWanderer

Kaz Wolfe

therefore, you can consider it to be type IWindowManager and execute against that.

SmokeDetector

[ SmokeDetector | MS ] Bad keyword in answer: Argument list too long when removing files in trash by cayley on askubuntu.com

Kaz Wolfe

that being said, you might not even need reflection. If the method you want to call is public, it'll just work.

Otherwise, you'll have to reflect on the object you just got back.

TheWanderer

23:05

sigh book2s.com/java/src/package/android/view/iwindowmanager.html

return new android.view.IWindowManager.Stub.Proxy(obj);

hmm

Kaz Wolfe

what are you trying to do?

TheWanderer

well it's mostly experimenting

but I need the setForcedDisplayDensityForUser method

Seth

@SmokeDetector what is it with long path tool.

what does that even do.

Kaz Wolfe

yeah, and what's your goal with this experiment?

TheWanderer

@KazWolfe change Android DPI using the internal API

Kaz Wolfe

23:08

is that even possible?

TheWanderer

well I'm trying to find out

Avery

it's possible

if you're root.

TheWanderer

I'm trying to work around root

I have a method that mostly works

Ubuntu Questions on U&L

Q: nmcli wifi access point isn't showing up

I've created an access point using nmcli however it isn't showing up . user@user:~# sudo nmcli connection NAME UUID TYPE DEVICE (green) Wired connection 1 00000000-000-0000-0000-000000000000 802-3-ethernet eth0 (green) wi...

TheWanderer

by writing to secure settings

Avery

23:09

just use the elevation glitch

Kaz Wolfe

you can also do it by running adb commands

wm density <value>

so look at whatever the wm command is.

TheWanderer

@Avery wat

@KazWolfe that's what I've been doing

where do you think I got the mWm thing?

Avery

I mean sure it was fixed in linux kernel v4.6.smth iirc but most phones are old

and can just use that exploit to create a runas/sudo file and then just do more craziness with that

or that was how it was iirc when i last used android like 3-4 months ago

Kaz Wolfe

yeah, mWm returns an existing object.

which does not need reflection.

so, in theory, it's two lines of code:

mWm = IWindowManager.Stub.asInterface(ServiceManager.checkService(Context.WINDOW_SERVICE));
mWm.setForcedDisplayDensity(Display.DEFAULT_DISPLAY, density);

TheWanderer

yeah but IWindowManager is a hidden class

can I ignore IntelliJ telling me the class isn't found?

Kaz Wolfe

23:13

er, it depends.

if you add android core or whatever provides android.view.IWindowManager, you can.

TheWanderer

I'd have to extract framework.jar

Kaz Wolfe

or add that to your classpath.

TheWanderer

how

wat

Kaz Wolfe

i think if you add that jar to your classpath, that should be enough.

TheWanderer

how

Byte Commander

23:16

wow, accepted and upvoted within probably less than 10 seconds...

TheWanderer

how is that possible

Byte Commander

that must be a truly satisfied customer

Kaz Wolfe

no idea

check your docs

TheWanderer

docs lol
