Android9.0 MTK flat horizontal screen Modify (app landscape forced + power logo / off charge horizontal screen animation + + RecoveryUI landscape)

It recommended to look at a longer article collection

Dismantling step

1, app forced cross-screen display, ignoring android: screenOrientation = "portrait" Properties

2, the screen coordinates of the touch screen is a cross-modified

3, boot animation landscape

4, the boot logo, horizontal screen off charging animation

5、RecoveryUI 横屏

The Code

1, app forced cross-screen display

Modified rotationForOrientationLw (), return to the default 270

frameworks\base\services\core\java\com\android\server\policy\PhoneWindowManager.java

 @Override
    public int rotationForOrientationLw(int orientation, int lastRotation, boolean defaultDisplay) {
        ....

        synchronized (mLock) {
        ...

        default:
                    // For USER, UNSPECIFIED, NOSENSOR, SENSOR and FULL_SENSOR,
                    // just return the preferred orientation we already calculated.
                    if (preferredRotation >= 0) {
                        return preferredRotation;
                    }
                    
                    // return Surface.ROTATION_0;
                    return Surface.ROTATION_270;//cczheng add for land scap
            }
        }
  }

The default attribute is mandatory activity SCREEN_ORIENTATION_LANDSCAPE

frameworks\base\services\core\java\com\android\server\wm\WindowManagerService.java

boolean updateOrientationFromAppTokensLocked(int displayId, boolean forceUpdate) {
        long ident = Binder.clearCallingIdentity();
        try {
            final DisplayContent dc = mRoot.getDisplayContent(displayId);
            // final int req = dc.getOrientation();
            int req = android.content.pm.ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE;//cczheng add for land scap
            if (req != dc.getLastOrientation() || forceUpdate) {
                if (DEBUG_ORIENTATION) {
                    Slog.v(TAG, "updateOrientation: req= " + req + ", mLastOrientation= "
                        + dc.getLastOrientation(), new Throwable("updateOrientation"));
                }
                dc.setLastOrientation(req);
                //send a message to Policy indicating orientation change to take
                //action like disabling/enabling sensors etc.,
                // TODO(multi-display): Implement policy for secondary displays.
                if (dc.isDefaultDisplay) {
                    mPolicy.setCurrentOrientationLw(req);
                }
                return dc.updateRotationUnchecked(forceUpdate);
            }
            return false;
        } finally {
            Binder.restoreCallingIdentity(ident);
        }
    }

DisPlayContent default display mRotation to 3 (270)

frameworks\base\services\core\java\com\android\server\wm\DisplayContent.java

/**
     * Current rotation of the display.
     * Constants as per {@link android.view.Surface.Rotation}.
     *
     * @see #updateRotationUnchecked()
     */
    // private int mRotation = 0;
    private int mRotation = 3;//cczheng add for land scap

Config_reverseDefaultRotation modify the default values ​​to true, the flip angle of the display

frameworks\base\core\res\res\values\config.xml

<!-- If true, the direction rotation is applied to get to an application's requested
         orientation is reversed.  Normally, the model is that landscape is
         clockwise from portrait; thus on a portrait device an app requesting
         landscape will cause a clockwise rotation, and on a landscape device an
         app requesting portrait will cause a counter-clockwise rotation.  Setting
         true here reverses that logic. -->
    <!-- cczheng add for land scap -->
    <bool name="config_reverseDefaultRotation">true</bool> 

    <!-- The number of degrees to rotate the display when the keyboard is open.
         A value of -1 means no change in orientation by default. -->
    <!-- cczheng add for land scap -->
    <integer name="config_lidOpenRotation">270</integer>

2, the screen coordinates of the touch screen is a cross-modified

Swap frame width and height, setting direction 270

frameworks\native\services\surfaceflinger\DisplayDevice.cpp

void DisplayDevice::setProjection(int orientation,
        const Rect& newViewport, const Rect& newFrame) {
    Rect viewport(newViewport);
    Rect frame(newFrame);

    const int w = mDisplayWidth;
    const int h = mDisplayHeight;

    Transform R;
    DisplayDevice::orientationToTransfrom(orientation, w, h, &R);

    if (!frame.isValid()) {
        // the destination frame can be invalid if it has never been set,
        // in that case we assume the whole display frame.
        //cczheng add for land scap
        // frame = Rect(w, h);
        if (w < h)
            frame = Rect(h, w);
        else
            frame = Rect(w, h);
    }
    ....

}

// clang-format off
DisplayDevice::DisplayDevice(
        const sp<SurfaceFlinger>& flinger,
        DisplayType type,
        int32_t hwcId,
        bool isSecure,
        const wp<IBinder>& displayToken,
        const sp<ANativeWindow>& nativeWindow,
        const sp<DisplaySurface>& displaySurface,
        std::unique_ptr<RE::Surface> renderSurface,
        int displayWidth,
        int displayHeight,
        bool hasWideColorGamut,
        const HdrCapabilities& hdrCapabilities,
        const int32_t supportedPerFrameMetadata,
        const std::unordered_map<ColorMode, std::vector<RenderIntent>>& hwcColorModes,
        int initialPowerMode)

      .....

    mHdrCapabilities = HdrCapabilities(types, maxLuminance, maxAverageLuminance, minLuminance);

    // initialize the display orientation transform.
    // setProjection(DisplayState::eOrientationDefault, mViewport, mFrame);
    //cczheng add for land scap
    setProjection(DisplayState::eOrientation270, mViewport, mFrame);
#ifdef MTK_SF_DEBUG_SUPPORT
    mFps = FpsCounterLoader::getInstance().create();
#endif
}

frameworks\native\services\surfaceflinger\SurfaceFlinger.cpp

void SurfaceFlinger::onInitializeDisplays() {
    // reset screen orientation and use primary layer stack
    Vector<ComposerState> state;
    Vector<DisplayState> displays;
    DisplayState d;
    d.what = DisplayState::eDisplayProjectionChanged |
             DisplayState::eLayerStackChanged;
    d.token = mBuiltinDisplays[DisplayDevice::DISPLAY_PRIMARY];
    d.layerStack = 0;
    //d.orientation = DisplayState::eOrientationDefault;
    //cczheng add for land scap
    d.orientation = DisplayState::eOrientation270;
    d.frame.makeInvalid();
    d.viewport.makeInvalid();
    d.width = 0;
    d.height = 0;
    displays.add(d);

    ....
}

3, boot animation landscape

CreateSurface swap () of w and h

frameworks\base\cmds\bootanimation\BootAnimation.cpp

status_t BootAnimation::readyToRun() {
    mAssets.addDefaultAssets();

    sp<IBinder> dtoken(SurfaceComposerClient::getBuiltInDisplay(
            ISurfaceComposer::eDisplayIdMain));
    DisplayInfo dinfo;
    status_t status = SurfaceComposerClient::getDisplayInfo(dtoken, &dinfo);
    if (status)
        return -1;

    // create the native surface
    /*sp<SurfaceControl> control = session()->createSurface(String8("BootAnimation"),
            dinfo.w, dinfo.h, PIXEL_FORMAT_RGB_565);*/

    //cczheng add for land scap  [S]
    sp<SurfaceControl> control;
    if(dinfo.w < dinfo.h)
        control = session()->createSurface(String8("BootAnimation"),
            dinfo.h, dinfo.w, PIXEL_FORMAT_RGB_565);
    else
        control = session()->createSurface(String8("BootAnimation"),
            dinfo.w, dinfo.h, PIXEL_FORMAT_RGB_565);
    //cczheng add for land scap  [E]

    SurfaceComposerClient::Transaction t;
    t.setLayer(control, 0x40000000)
        .apply();

    .....

}

Boot animation replacement behind the supplement. . .

4, the boot logo, horizontal screen off charging animation

Boot logo screen resolution is defined to correspond to the location of the resource folders

vendor \ mediatek \ proprietary \ bootable \ bootloader \ lk \ project \ xxxx.mk not then see below

device\mediateksample\xxxx\ProjectConfig.mk

mk of BOOT_LOGO = wxga

Resource file corresponding to the location in the vendor / mediatek / proprietary / bootable / bootloader / lk / dev / logo / wxga

You can see in the picture wxga are vertical screen, and wxganl already is a cross-screen picture

Then we will modify the wxganl to BOOT_LOGO

Next also we need to continue to modify the angle display, still into 270, otherwise there will be Huaping phenomenon

The first picture corresponds uboot boot display

vendor\mediatek\proprietary\bootable\bootloader\lk\platform\mt6765\mt_logo.c

void init_fb_screen()
{
    .....

    // in JB2.MP need to allign width and height to 32 ,but jb5.mp needn't
    phical_screen.needAllign = 1;
    phical_screen.allignWidth = ALIGN_TO(CFG_DISPLAY_WIDTH, MTK_FB_ALIGNMENT);

    /* In GB, no need to adjust 180 showing logo ,for fb driver dealing the change */
    /* but in JB, need adjust it for screen 180 roration           */
    phical_screen.need180Adjust = 0;   // need sync with chip driver

    dprintf(INFO, "[lk logo: %s %d]MTK_LCM_PHYSICAL_ROTATION = %s\n",__FUNCTION__,__LINE__, MTK_LCM_PHYSICAL_ROTATION);

    if (0 == strncmp(MTK_LCM_PHYSICAL_ROTATION, "270", 3)) {
        phical_screen.rotation = 270;
    } else if (0 == strncmp(MTK_LCM_PHYSICAL_ROTATION, "90", 2)) {
        phical_screen.rotation = 90;
    } else if (0 == strncmp(MTK_LCM_PHYSICAL_ROTATION, "180", 3) && (phical_screen.need180Adjust == 1)) {
        phical_screen.rotation = 180;
    } else {
        phical_screen.rotation = 270;//cczheng add for land scap
    }

    ....

The second picture corresponds kernel boot display

vendor\mediatek\proprietary\external\libshowlogo\charging_animation.cpp

int anim_fb_init(void)
{
     .....

    phical_screen.needAllign = 1;
    phical_screen.need180Adjust = 1;
    phical_screen.fb_size = fb_size;
    if (MTK_LOG_ENABLE == 1) {
        SLOGD("[libshowlogo: %s %d]MTK_LCM_PHYSICAL_ROTATION = %s\n",__FUNCTION__,__LINE__, MTK_LCM_PHYSICAL_ROTATION);
    }

    if(0 == strncmp(MTK_LCM_PHYSICAL_ROTATION, "270", 3))
    {
        phical_screen.rotation = 270;
    } else if(0 == strncmp(MTK_LCM_PHYSICAL_ROTATION, "90", 2)){
        phical_screen.rotation = 90;
    } else if(0 == strncmp(MTK_LCM_PHYSICAL_ROTATION, "180", 3) && (phical_screen.need180Adjust == 1)){
        phical_screen.rotation = 180;
    } else {
        phical_screen.rotation = 270;//cczheng add for land scap
    }
    if (MTK_LOG_ENABLE == 1) {
        SLOGD("[libshowlogo]phical_screen: width= %d,height= %d,bits_per_pixel =%d,needAllign = %d,allignWidth=%d rotation =%d ,need180Adjust = %d\n",
                phical_screen.width, phical_screen.height,
                phical_screen.bits_per_pixel, phical_screen.needAllign,
                phical_screen.allignWidth, phical_screen.rotation, phical_screen.need180Adjust);
        SLOGD("[libshowlogo: %s %d]show old animtion= 1, running show_animationm_ver %d\n",__FUNCTION__,__LINE__, show_animationm_ver);
        SLOGD("[libshowlogo: %s %d]draw_anim_mode = 1, running mode %d\n",__FUNCTION__,__LINE__, draw_anim_mode);
    }

    return 0;
}

If the charging animated picture dislocation phenomenon, mostly because the graphics rendering and screen dot size mismatch caused. By adjusting the position parameter cust_display.h

After Android M: /vendor/mediatek/proprietary/external/libshowlogo/cust_display.h

Android M 前： /vendor/mediatek/proprietary/bootable/bootloader/lk/target/${PROJECT}/include/target/cust_display.h

(1, using animation schemes to adjust the old version are set as follows,

BAR_LEFT #define (215)
#define BAR_TOP (156)
#define BAR_RIGHT (265)
#define BAR_BOTTOM (278)
to open the first image point with the windows mentioned in the drawing software, a pixel is adjusted according to the cell border.

Origin of the coordinate reference here is to the upper left corner, upper left corner of the background image is (0,0), these four values are relative to the upper left corner coordinates determined, therefore RIGHT> LEFT, BOTTOM> TOP
tips: 1) open the drawing software, choose View -> zoom -> customize picture to put 800%
2) select View -> zoom -> show grid
so you can see a one pixel
(2, using the new version animation program adjust the following settings:

#define CAPACITY_LEFT (278) 
#define CAPACITY_TOP (556)
#define CAPACITY_RIGHT (441)
#define CAPACITY_BOTTOM (817)

5、RecoveryUI 横屏

Prior to refer to the article written by MTK Recovery mode landscape modification (applies to 6.0 + 8.1 + 9.0)

6, system navigation bar position adjustment, after a cross default on the left screen navigationBarPosition

As the flat items, the need to change the position to the bottom, directly modify navigationBarPosition () Returns NAV_BAR_BOTTOM

frameworks\base\services\core\java\com\android\server\policy\PhoneWindowManager.java

@NavigationBarPosition
    private int navigationBarPosition(int displayWidth, int displayHeight, int displayRotation) {
        //cchzneg annotaion for land scape
        /*if (mNavigationBarCanMove && displayWidth > displayHeight) {
            if (displayRotation == Surface.ROTATION_270) {
                return NAV_BAR_LEFT;
            } else {
                return NAV_BAR_RIGHT;
            }
        }*/
        return NAV_BAR_BOTTOM;
    }

Such a position is changed to the bottom, but the three buttons are superimposed together, to modify the layout display SystemUI

vendor\mediatek\proprietary\packages\apps\SystemUI\src\com\android\systemui\statusbar\phone\NavigationBarView.java

private void updateRotatedViews() {
        //cczheng change rot0 rot90 for landscape
        mRotatedViews[Surface.ROTATION_0] =
                mRotatedViews[Surface.ROTATION_180] = findViewById(R.id.rot90);
                // mRotatedViews[Surface.ROTATION_180] = findViewById(R.id.rot0);
        mRotatedViews[Surface.ROTATION_270] =
                mRotatedViews[Surface.ROTATION_90] = findViewById(R.id.rot0);
                // mRotatedViews[Surface.ROTATION_90] = findViewById(R.id.rot90);        

        updateCurrentView();
    }

Incidentally then adjust the default height under NavigationBarView Back key and left much of a problem area

vendor\mediatek\proprietary\packages\apps\SystemUI\src\com\android\systemui\statusbar\phone\NavigationBarInflaterView.java

private View createView(String buttonSpec, ViewGroup parent, LayoutInflater inflater) {
        View v = null;
        String button = extractButton(buttonSpec);
        if (LEFT.equals(button)) {
             //cchzheng change NAVSPACE to MENU_IME for small left back click area
            String s = Dependency.get(TunerService.class).getValue(NAV_BAR_LEFT, MENU_IME_ROTATE/*NAVSPACE*/);
            button = extractButton(s);
        } else if (RIGHT.equals(button)) {
            String s = Dependency.get(TunerService.class).getValue(NAV_BAR_RIGHT, MENU_IME_ROTATE);
            button = extractButton(s);
        }

        ...

frameworks\base\core\res\res\values\dimens.xml

 <!-- Height of the bottom navigation / system bar. -->
    <!--cczheng change 48dp to 30dp-->
    <dimen name="navigation_bar_height">30dp</dimen>

ok, that's it, perfect horizontal screen adaptation
