ANXCamera Magisk Module

[Theo-user]

Describe the bug After installing the module without errors the ANX camera apk crashes when launching. Errors here: https://paste.crdroid.net/jgWxeP

To Reproduce Steps to reproduce the behavior: Install module here: https://androidfilehost.com/?fid=14655340768118463076 Restart and run ANXCamera

Expected behavior Load the camera like when using Magisk.

Screenshots If applicable, add screenshots to help explain your problem.

Smartphone (please complete the following information): Poco F3 Crdroid 9.14 InfiniR_Alioth_v2.67 kernel

Additional context I have an issue when using Magisk without Zygist and and with MagiskHide. I need to allow SU for the camera apk. Doing this with KernelSU doesn't resolve the issue like with Magisk. It's most likely permissions but I've not been able to pinpoint it.

[tiann]

Disable the "umount modules by default" in settings and try it again.

[Theo-user]

Same error https://paste.crdroid.net/ljOhZA

[Theo-user]

Still not working with 0.6.2

[tiann]

What if you grant root permission to the camera?

[Theo-user]

I did both as you suggested but the error persists. Root permission is required for the camera with Magisk if I use Magisk hide and enforced root. No such luck with KernelSU.

[tiann]

Please upload the bugreport in KernelSU manager.

I think this is a module issue, the log show that:

open libmialgoengine.so failed

But the module don't have any file named that.

Please exec ls -alZ /vendor

Please use adb shell and su to list the files:

1. adb shell
2. su
3. ls -alZ /vendor/lib64

[Theo-user]

Will this suffice?

[tiann]

Did you use su to execute it?

[Theo-user]

I believe I did now.

Thanks.

[tiann]

Please use adb shell or other terminal emulator, the SELinux context is missing.

[tiann]

the logcat file of your bugreport is empty.

[Theo-user]

Please check this one

[tiann]

Please use adb shell execute setprop debug.ld.all dlopen,dlerror and reproduce the bug and then upload the bugreport.

[tiann]

I believe this is a module issue.

Your logcat shows that:

And i decompile your camera APK:

public class MiCamAlgoInterfaceJNI {
    public static final String LIB_NAME = "camera_algoup_jni.xiaomi";
    public static final String TAG = "MiCamAlgoInterfaceJNI";

    static {
        try {
            Log.e(MiCamAlgoInterfaceJNI.class.getSimpleName(), "start loading camera_algoup_jni.xiaomi");
            System.loadLibrary(LIB_NAME);
            Log.d(TAG, "static initializer: loadLibrary camera_algoup_jni.xiaomi");
        } catch (UnsatisfiedLinkError e) {
            String str = TAG;
            Log.e(str, "can not load library:camera_algoup_jni.xiaomi : " + Log.getStackTraceString(e));
        }
    }

    public static native long createSessionByOutputConfigurations(BufferFormat bufferFormat, List<OutputConfiguration> list, TaskSession.SessionStatusCallback sessionStatusCallback);

    public static native long createSessionWithSurfaces(BufferFormat bufferFormat, List<Surface> list, TaskSession.SessionStatusCallback sessionStatusCallback);

    public static native int deInit();

    public static native int destroySession(long j);

    public static native int flush(long j);

    public static native int getVersionCode();

    public static native int init(String str);

    public static native int processFrame(long j, FrameData frameData, TaskSession.FrameCallback frameCallback);

    public static native int processFrameWithSync(long j, List<FrameData> list, Image image, int i);

    public static native int setMiViInfo(String str);
}

And in libcamera_algoup_jni.xiaomi.so, it shows:

  else
  {
    v26 = dlerror();
    __android_log_print(6LL, "MI_Algo_JNI", "init: open %s error: %s", "/vendor/lib64/libmialgoengine.so", v26);
    v27 = (*(__int64 (__fastcall **)(__int64 *, const char *))(*v8 + 48))(v8, "java/lang/RuntimeException");
    if ( v27 )
      (*(void (__fastcall **)(__int64 *, __int64, const char *))(*v8 + 112))(v8, v27, "open libmialgoengine.so failed!");
    (*(void (__fastcall **)(__int64 *, __int64))(*v8 + 184))(v8, v27);
    result = 0xFFFFFFFFLL;
  }

This is the error cause. But in my MIUI devices, it cannot open /vendor/lib64/libmialgoengine.so too, but it don't throw the error:

  {
    v25 = sub_E978();
    sub_E750(6LL, "MI_Algo_JNI", "init: open %s error: %s", "/vendor/lib64/libmialgoengine.so", v25);
    result = 0xFFFFFFFFLL;
  }

I don't know why it works fine when using Magisk.
