[RK3288][Android6.0] 调试笔记 --- 设置中文为默认输入法

Platform: RK3288

OS: Android 6.0

Kernel: 3.10.92

添加方法:

1. 添加第三方apk

路径: rk3288/device/rockchip/rk3288/Sougou:

Android.mk    //标准预置第三方apk方法

LOCAL_PATH := $(call my-dir)

include $(CLEAR_VARS)

LOCAL_MODULE := sougoushurufa

LOCAL_MODULE_CLASS := APPS

LOCAL_MODULE_TAGS := optional

LOCAL_BUILT_MODULE_STEM := package.apk

LOCAL_MODULE_SUFFIX := $(COMMON_ANDROID_PACKAGE_SUFFIX)

#LOCAL_PRIVILEGED_MODULE :=

#LOCAL_OVERRIDES_PACKAGES :=

LOCAL_SRC_FILES := $(LOCAL_MODULE).apk

#LOCAL_REQUIRED_MODULES :=

LOCAL_CERTIFICATE := PRESIGNED

include $(BUILD_PREBUILT)

2. 设置默认属性以及加载到database中

3. 使能所有输入法

默认情况下只有一种输入法是被使能的,如果要使能全部, 可做如下修改

[kris@ecovacs:~/rk3288/frameworks/base]$ g df

相关知识点:

资源文件路径:

rk3288/frameworks/base/packages/SettingsProvider/res/values/defaults.xml

系统自带输入法路径:

rk3288/packages/inputmethods

由于要新建git,所以上面例子中将输入法直接放在rk3288/device/rockchip/rk3288下面了.

数据库位置:

/data/system/users/0/

获取默认输入法:

adb shell settings get secure default_input_method
