21-Android13.0 system customization

1. Boot LOGO customization

The boot LOGO is divided into two parts, namely the Uboot stage and the Kernel stage

Uboot stage parsing image kernel-5.10/logo.bmp

Kernel stage parsing image kernel-5.10/logo_kernel

$ ls kernel-5.10/
	logo.bmp
	logo_kernel.bmp

2. Boot animation customization

$ ls device/rockchip/common/bootanimation.zip

3. Default screen orientation

Modify display orientation

$ vim device/rockchip/rk356x/BoardConfig.mk

	SF_PRIMARY_DISPLAY_ORIENTATION := 0 	//default
	SF_PRIMARY_DISPLAY_ORIENTATION := 90 	//90°
	SF_PRIMARY_DISPLAY_ORIENTATION := 180	//180°
	SF_PRIMARY_DISPLAY_ORIENTATION := 270	//270°

Modify touch direction

Take the TP with a 7-inch screen as an example, you can modify the direction you want through this.

$ vim kernel-5.10\arch\arm64\boot\dts\rockchip\rk3568-kickpi-lcd-lvds0-7-1024-600.dtsi
		
		gtp_change_x2y = <0>; //1 is the X-Y axis alignment
		gtp_overturn_x = <0>; //1 is the reverse of the X axis
		gtp_overturn_y = <0>; //1 is the reverse of the Y-axis.

4. Default hide status bar

6. Built-in third-party APP

Refer to Settings2.apk

Rk-android13.0\ vendor\ rockchip\ common\ apps\ Settings2 put your apk and Android.bp

Android.mk way

###############################################################################

    enforce_uses_libs: false,
}

Add compilation in rk-android13.0\ vendor\ rockchip\ common\ apps\ apps.mk

PRODUCT_PACKAGES += \

7. Boot the self-starting APP

**After receiving the boot broadcast, start the APP **

Modify and increase the permissions of the APP and broadcast to receive AndroidManifest.xml

<uses-permission android:name="android.permission.START_ACTIVITIES_FROM_BACKGROUND" />
<uses-permission android:name="android.permission.USE_FULL_SCREEN_INTENT" />
<uses-permission android:name="android.permission.SYSTEM_ALERT_WINDOW" />
<uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED" />

<application
        <receiver
            android:name=".MyReceiver"
            android:enabled="true"
            android:exported="true">
            <intent-filter android:priority="1000">
                <action android:name="android.intent.action.BOOT_COMPLETED"></action>
            </intent-filter>
        </receiver>
</application>

Increase broadcast reception MyReceiver.java

package com.example.myapplication;
import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.util.Log;

public class MyReceiver extends BroadcastReceiver {
    public MyReceiver() {
    }

    @Override
    public void onReceive(Context context, Intent intent) {
        if (intent.getAction().equals("android.intent.action.BOOT_COMPLETED")) {
            Intent i = new Intent(context, MainActivity.class);
            i.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
            context.startActivity(i);
            Log.i("kickpi", "onReceive: start app !!!");
        }
    }
}

Pre-install the app to /system/priv-app/

Method 1, compile and pre-install to the source code, refer to [Built-in third-party APP] (#6. Built-in third-party APP)

Method 2, push method pre-installed

adb root; adb remount;
adb push ./app /system/priv-app/

8. Default language

$ vim build/target/product/full_base.mk
	PRODUCT_LOCALES := en_US

Options

Description

en_US

English

zh_CN

Chinese

9. Default time zone

10. Default never sleeps

$ vim device/rockchip/rk356x/overlay/frameworks/base/packages/SettingsProvider/res/values/defaults.xml
	<integer name="def_screen_off_timeout">2147483647</integer>

11. Default disable lock screen

$ vim frameworks/base/packages/SettingsProvider/res/values/defaults.xml
	<bool name="def_lockscreen_disabled">true</bool>

12. Signature APK

Resign in the SDK source code

$ cd rk-android13.0/
$ java -Xmx2048m -Djava.library.path="out/host/linux-x86/lib64" \
-jar out/host/linux-x86/framework/signapk.jar  --disable-v2 \
-w build/target/product/security/platform.x509.pem \
build/target/product/security/platform.pk8 \
old.apk new.apk

**Re-sign with signature-related documents **

Signature-related files required in the SDK

out/host/linux-x86/lib64	// Avoid Java library problems
out/host/linux-x86/framework/signapk.jar
build/target/product/security/platform.x509.pem
build/target/product/security/platform.pk8

Re-sign according to the provided documents, and adjust the specific path by yourself

signature package rk-android13.0-key.tar.gz
$ tar -xvf rk-android13.0-key-20240919.tar.gz
$ ls rk-android13.0-key
$ java -Xmx2048m -Djava.library.path="rk-android13.0-key/lib64" \
-jar rk-android13.0-key/signapk.jar  --disable-v2 \
-w rk-android13.0-key/platform.x509.pem \
rk-android13.0-key/platform.pk8 \
old.apk new.apk

13.Network ADB

The network port ADB needs to start the 5555 port service first.

PS C:\Users\16708\Desktop> adb tcpip 5555
PS C:\Users\16708\Desktop> adb connect 192.168.77.170
connected to 192.168.77.170:5555
PS C:\Users\16708\Desktop> adb devices
List of devices attached
7c001075a313c7c1c12     device
192.168.77.170:5555     device

PS C:\Users\16708\Desktop> adb -s 192.168.77.170:5555 shell
apollo-p2:/ $ su

When powered on, port 5555 is started by default.

It needs to be operated via USB adb.

 adb root
 adb remount
 adb pull /system/build.prop

add in build.prop Add this line

+ service.adb.tcp.port=5555

substitute entry

 adb push .\build.prop /system/build.prop

14. HDMI in APK Customization

         rootView = (RelativeLayout) findViewById(R.id.root_view);
         rootView.setOnClickListener(this);

15. Modify the debugging port baud rate

Modify the path:

 rk-android13.0\kernel-5.10\arch\arm64\boot\dts\rockchip\rk3568-android.dtsi

Modify rockchip, baudrate content:

fiq-debugger {
		compatible = "rockchip,fiq-debugger";
		rockchip,serial-id = <2>;
		rockchip,wake-irq = <0>;
		/* If enable uart uses irq instead of fiq */
		rockchip,irq-mode-enable = <1>;
		rockchip,baudrate = <1500000>;  /* Only 115200 and 1500000 */
		interrupts = <GIC_SPI 252 IRQ_TYPE_LEVEL_LOW>;
		pinctrl-names = "default";
		pinctrl-0 = <&uart2m0_xfer>;
		status = "okay";
	};

16.Modify UI resolution

The default resolution of the Android system UI is 1080P, and you can also modify the resolution of the UI through commands.

The following modification commands are available under different shells:

(console)$ wm size 4096x2560
(ADB)$ adb shell wm size 4096x2560

Command format: wm size < width > x < height >
