Give system service permission to external storage

Hi,
I'm studying how PackageManagerService works, and i noticed that if an application was downloaded to /data/app i can access the file and open inputstream .
but if APK was downloaded to SD card, i can't access the file from PackageManagerService.
is there something i can do?
I want to be able to read the APK before it get installed...
Thanks,

pi.publicSourceDir = apk file path

not sure i follow you.
I'm in the packageManagerService context, i don't have PackageInfo (the application is still not installed)

You could hook PermissionGranter and give the process extra permissions, or see where the system is actually parsing the APK's manifest before installing it.

Thanks, what I don't understand is, if i give my xposed module permissions to read external storage, why does it still can't read it?

So just to make sure I understand, I can create a service and run it from the hooked method and it should work?
if so, i have another question
How can i stop the original method from running until a point i allow it to continue?
Thanks GermainZ !

I don't understand how you read that from my reply, to be honest. Here's what I meant:
Hooked code *is not* run as your app. The hooked code is run as the hooked app.
If the hooked app can't do X, then the hooked code can't do X either.
Your app's permissions do not affect the hooked code in any way, only normal (not hooked) code.

Using the normal ways you'd normally use if it weren't an Xposed module, in the beforeHookedMethod hook. I'm not familiar with the exact methods, you can look that up. Just be aware that blocking it for too long will cause an ANR.

how to modify android.os.Build's static field?

Hi, I'm just use Xposed to dev a simple project.
I'm trying to modify device info by using Xposed. When I hook TelephonyManager.getDeviceId, return the value that just what I set.
But I can't find out how to modify the fields in andoid.os.Build. They are FINAL fields and Xposed can just hook on methods but not fields.
I get a way to set the fields using XposedHelpers.setStaticObjectField. It can ONLY modify ONCE when the target apk has not started. When the target apk( such as device info viewer ) started, I have to reboot or force close the apk because of the handleLoadPackage method can not reinvoke.
Waiting online for any solution. Thanks very much.

I don't know which final field you are trying to change, but most of them get their values from getString(), getStringList() or getLong() methods.
You need to hook in these methods, read their "property" parameter ( param.args[0] ) to see if it is the one you want to change, and finally change the method result ( param.setResult() ).

Hello. Is there a solution to change the fields like Build.MODEL on the fly? Any examples not worked. Thanks.

Some fields can't be replaced, am I right?

It's worked only in own application with this code. In other apps it's not worked. I need to make changes to apply to all applications.
PS: Sorry for my bad English.

You can do this only when the Java VM is being initialized in handle load package.

There is no need for restarts, just set a new value in the Xposed handleLoadPackage callback for the applications you want to modify values.
Note that changing Build properties for Android might result in a bootloop.
Edit: if you don't known about handleLoadPackage , you need to do some studying ...

This all can be simplified by XposedHelpers.setStaticObjectField(clazz, name, value)

[Q] Xposed for nougat to read prefs ith fbe or without

as xposed for nougat is already arrived officially many modules are not working
there is either File Based Encryption in data partition or by wiping data partition from twrp removes it
anybody able to read shared_prefs either with FBE or without it successfully so that it works properly,if that so please let us know how so that other module developers can fix their modules as well

the issue is that you can not read Preferences like used to before
HTML:
pref = new XSharedPreferences(BuildConfig.APPLICATION_ID);
so any values saved in shared_prefs can not be read by xposed at the moment on nougat atleast on galaxy s7 930F
i am looking for workaround,i tried putting prefs in /data/here it works but not so stable

This seems to work OK for me:
https://developer.android.com/refer...xt.html#createDeviceProtectedStorageContext()
https://developer.android.com/refer...renceManager.html#setStorageDeviceProtected()
I adjusted one of my modules to use Device Protected Storage and it seems to initialize preferences fine on FBE devices.

i need tester for this
because i am unable to boot if i flash magisk or supersu without formating data partition ,so i format /data partition and rooted which eventually remove encryption from /data partition so unable to test
i saw your commit but would be fine if i got tested with encrypted /data partition to test

I have the same issue. To fix it, actually, we don't need to touch device protected storage. But we do need to set up the package folder permission and the preference file permission.
I set the folder to 711, and the file to 644. Then the preference works well. XSharedPreference.makeWorldReadable should set the file permission. And you may need to set up the folder permission manually with setExecutable(true, false).

The thing is OS automatically changes permissions of preference files back and removes readable flags. This happens when preferences are committed to the filesystem.
To work around this I had to implement a solution that tracks those changes and adjusts permissions as necessary.

Yeah, you're right. So we need to proactively set it readable to work around it.
By the way, Gravity Box is a great project. It helps me a lot on the exposed development.

Hello, Can i help me.
Android 7.1.1 (Nougat) can not be used XSharedPreference can not read the contents of the file,How to solve this problem?Thank you

xPrivacyLUA - Export All Settings

Export All Setting is dimmed. I know that's because there's something missing from the kernel (I'm on LineageOS).
Is there a workaround to copy a file from this phone to another phone?
If so, what file? Do I need to worry about the new phone not having all of the same apps?
Thanks!

I think the files are:
xlua.db
xlua.db-journal
with a root file explorer located in
/data/system/xlua
These are the files to delete if having major problems with xprivacylua. It will revert xprivacylua to default settings ie: first installation.
You could try to copy these files and replace them on a different phone.
If you export/copy the settings it only effects the same apps that you've restricted on your original phone to the new phone.
So any new apps or apps that are different from original phone will have to be restricted ( if needed ).
From memory exporting settings will include any hooks restrictions from the repo section as well but may have to redownload the hooks themselves ( just going off memory haven't done it in a while ).

is it still working properly on android Q and up? I read somewhere is HideMyAppList is better?

Hidemyapplist is best in hiding apps from other apps and is non detectable. But xprivacy does other hiding jobs better and is detectable too.

We don't need to care about personality of creator of the XprivacyLua, @M66B .
He already made an incredible, an amazing, an wonderful, contribution to the community and deserves all the credits and loves for that.

This is an old thread. I have Pro, but wasn't able to do it, probably because Lineage doesn't have some piece of Android linked in.
