1. Install the input method and view the input method package name

This time we are going to install Baidu input method. The installation method is as follows:

1.1 Installation using adb command line

Use the win+R key combination on the computer keyboard to pop up the input box, enter cmd to enter the computer terminal, and execute the following command:

#查看是否识别到adb设备
adb.exe devices

#让系统获取root权限
adb.exe root#

让系统可读可写
adb.exe remount#

开始安装
adb.exeinstall/your/target/path/baidu.apk

1.2 U disk/TF card installation

Place the input method apk in a U disk/TF, insert it into the motherboard and let it recognize the device, then go to the system desktop and find the [Explorer] application, then click on the U disk input method apk application to install it.

Installation Successful

1.3 View the input method package name

# ime list -s
com.baidu.input/.ImeService

The output result is the package name/class name of the input method.

2. System pre-installed input method applications

Place the Baidu input method APK that needs to be pre-installed
in the device/rockchip/rk356x/rk3566_r/preinstall_del/directory

(If there is no preinstall_del directory, create one manually) and add the following files:

• Android.mk
• baidu.apk（APK）
• preinstall.mk

Android.mk file content:

include $(call all-subdir-makefiles)

Preinstall.mk file contents:

PRODUCT_PACKAGES += baidu

Note: baidu is the name of the APK, for example, baidu.apk.

3. Modify the input method environment variables

Add the Baidu input method package name/class name obtained in the first step to the following file:

frameworks/base/packages/SettingsProvider/res/values/defaults.xml

The content is as follows:

<!-- should show the screenshot button default -->
<integername="def_screenshot_button_show">0</integer>
  
  +<!-- set default input method-->
  +<stringname="config_default_input_method"translatable="false">com.baidu.input/.ImeService</string>
</resources>

4. Modify the default input method

Add the previous input method environment to the following file:

frameworks/base/packages/SettingsProvider/src/com/android/providers/settings/DatabaseHelper.java

Add the following content:

classDatabaseHelperextendsSQLiteOpenHelper{
  
  loadIntegerSetting(stmt, Settings.Secure.SLEEP_TIMEOUT,
                     R.integer.def_sleep_timeout);
  
  + loadStringSetting(stmt, Settings.Secure.DEFAULT_INPUT_METHOD, R.string.config_default_input_method);//add hjt
/*
* IMPORTANT: Do not add any more upgrade steps here as the global,
* secure, and system settings are no longer stored in a database

After adding, recompile the source code.

5. Check whether Baidu Input Method is the default input method

Command Line

# settings get secure default_input_method
com.baidu.input/.ImeService

Set the default input method successfully
