[APP] P9 Camera APK port - Honor 8 Themes, Apps, and Mods

I ported the Camera apk, use recovery/root to put the apk under /system/priv-app & remove HwCamera2 folder
The black and white mode won't show up. The FRD camera configuration server doesn't enables monochrome mode. I am working on modifying it, not sure if it will work or if it's even possible.
Some info:
hwcam/hwcam.ddt.so - this represents the vendor tags the phone is supporting. Built from arrays of (I think) name, tag, size, type, reserved(unknown/0).
HwCamCfgSvr daemon, I think it's using libHwCamCfgSvr.so and communicates through Binder to query the device capabilities.
hwcam.hi3650.m.FRD.so / hwcam.hi3650.m.EVA.so - this library responds to the query requests, and seems to be implemented for the device. FRD is honor, EVA is P9.
How it checks if the device has monochrome?
1. The cameramanger has the CameraCharacteristics interface. The camera apk checks for CameraCharacteristicsEx.HUAWEI_MONO_MODE_SUPPORTED. That's translated through the camera.hi3650.so to com.huawei.device.capabilities.monoModeSupported, monoModeSupported is checked against the CamCfgSvr, the hwcam.ddt.so translates that to 0x80000056. The hwcam.hi3650.m.FRD.so responds. P9 uses 0x80000056 and this tag seems to be initialized with the value 2.
WhiteBlackMode isAvailable code:
Code:
@Override
public boolean isAvailable(final SilentCameraCharacteristics silentCameraCharacteristics) {
final Byte b = silentCameraCharacteristics.get(CameraCharacteristicsEx.HUAWEI_MONO_MODE_SUPPORTED);
final byte[] array = silentCameraCharacteristics.get(CameraCharacteristicsEx.HUAWEI_AVAILABLE_DUAL_PRIMARY);
if (b != null && array != null) {
for (int length = array.length, i = 0; i < length; ++i) {
if (array[i] == b) {
return true;
}
}
}
return false;
}
HUAWEI_MONO_MODE_SUPPORTED value is checked against HUAWEI_AVAILABLE_DUAL_PRIMARY. I guess P9 uses 2, which is equals to DUAL, meaning the mode is supported on the dual lens only?
If anyone has some ideas, or wants more info, PM me.
The APK in the attachments.

Besides monochrome being disabled, yes it is.

Great job :good: :highfive:

Ok, so if someone is good with DexPatcher, PM me.
I think I got something simple enough that would work.

nice work, thanks for sharing

I havent modified it, you must replace the normal camera with this apk on /system/priv-app.

Does the dual camera work? I mean, when you take a picture, it uses both cameras at same time to improve the photo?

The APK itself isn't really aware of this, I believe. The only thing missing is making the "monochrome" capability on, as the sensor itself should support it.
I see two options, one is to modify the camera service to say it supports monochrome, and the other is to modify the APK to assume that monochrome is supported.
The second option should be easy using DexPatcher, but I didn't have time for this yet.
If anyone has DexPatcher installed and wants to help, I'll show you what to modify, that should be like one line of code.
Some instructions about installation:
Using root/recovery go to /system/priv-app, remove the HwCamera2 folder, push HwCamera2.apk to /system/priv-app/HwCamera2.apk
For uninstall, remove the apk, and use the folder instead. If no backup was made, use the full firmware update using original recovery to restore.
