[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
diff --git a/core/java/com/android/internal/inputmethod/InputMethodUtils.java b/core/java/com/android/internal/inputmethod/InputMethodUtils.java

                 }

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
