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

5. Default hide navigation 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

7. Boot the self-starting APP

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

1. 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>

1. 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 !!!");
        }
    }
}

1. 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";
	};
