怎样去解决安卓Q RK3326编译错误的问题呢

25.编译错误 UnicodeEncodeError: ‘ascii’ codec can’t encode characters in position 47-50: ordinal not in range(128)
错误日志提示的很明显，存在中文字符


Traceback (most recent call last):
  File "build/make/tools/fileslist_util.py", line 68, in
    main(sys.argv)
  File "build/make/tools/fileslist_util.py", line 62, in main
    PrintCanonicalList(args[0])
  File "build/make/tools/fileslist_util.py", line 30, in PrintCanonicalList
    print "{0:12d}  {1}".format(line["Size"], line["Name"])
UnicodeEncodeError: 'ascii' codec can't encode characters in position 47-50: ordinal not in range(128)


检查FAILED得命令，包含如下


build/make/tools/fileslist_util.py -c out/target/product/xxxx/installed-files.json out/target/product/xxxx/installed-files.txt


这个fileslist_util.py是将json数据转换为txt文件的。我们运行该命令，发现在


1416  /system/usr/keylayout/Vendor_xxxx_Product_xxxx.kl


处停止。打开out/target/product/xxxx/installed-files.json，发现Vendor_xxxx_Product_xxxx.kl后面的modulename存在中文字符，
进入对应目录下查找到该文件重命名或者删除即可。我这里是使用删除的方式，因为我是不小心复制了个快捷方式出来。


24.修改系统设置Preference主题样式




自定义主题要看是在哪里用得
  @style/自定义主题
   


23.新增可以导入的jar包
Android.mk


//开始
include $(CLEAR_VARS)
sdk_src_dir = sdk/src/main/java
LOCAL_MODULE := myjar
LOCAL_MODULE_TAGS := optional
LOCAL_JACK_ENABLED = disabled
LOCAL_PROGUARD_ENABLED := full obfuscation
LOCAL_PROGUARD_FLAG_FILES := proguard.cfg
LOCAL_SRC_FILES :=
    $(call all-java-files-under,src


LOCAL_AIDL_INCLUDES :=
        $(call all-Iaidl-files-under, $(sdk_src_dir))
        $(LOCAL_PATH)/$(sdk_src_dir)


LOCAL_JAVACFLAGS := -Xlint:all
include $(BUILD_STATIC_JAVA_LIBRARY)


## copy jar
intermediates.COMMON := $(call local-intermediates-dir,COMMON)
full_classes_jar := $(intermediates.COMMON)/classes-full-debug.jar
$(shell cp -rf $(full_classes_jar) $(LOCAL_PATH)/myjar.jar)
full_classes_jar := $(intermediates.COMMON)/classes-proguard.jar
$(shell cp -rf $(full_classes_jar) $(LOCAL_PATH)/myjar-proguard.jar)
//结束，这一段是开始编译出jar包，并复制到当前目录下来


//这一段使用别名。使得在其他LOCAL_STATIC_JAVA_LIBRARIES中可以使用
LOCAL_PREBUILT_STATIC_JAVA_LIBRARIES :=
        myjarAlias:myjar.jar
include $(BUILD_MULTI_PREBUILT)

init.rc中开启和关闭AUTOLOG的方式
**#####-->    device/rockchip/common/init.rk30board.rc b/device/rockchip/common/init.rk30board.rc**
on property:vtech.prop.logcat.enable=true
    start vtechlogcat

    stop vtechlogcat
    chmod 777 /vtech/log.txt
    chown system system /vtech/log.txt

    class main
    disabled
    user root
   group root shell


#####–> device/rockchip/common/sepolicy/vendor/init.te


## init.te中需要一个自动转换作用与
domain_auto_trans 即:在init域中执行logcat_exec域的相关操作时，我们将他切换到logpersist域中去
/system/bin/logcat是属于u:object_r:logcat_exec:s0
但是在init进程中他的执行是以logpersist的域的方式执行的，所以相关权限需要添加到logpersist.te中去
device/rockchip/common/sepolicy/vendor/init.te
domain_auto_trans(init, logcat_exec, logpersist)


#####–> 如下部分是解决logpersist.te的neverallow规则限制

2.17.1
19.手动选择音频输入设备
audio_policy_configuration.xml 中定义设备名称
画个重点。。。在录音过程中，不要进行通路切换，要先切换了才能去录音


//定义设备端口名称 这是一个名为Built-In Mic的板载mic

                                                  samplingRates="16000" //采样率
                             channelMasks="AUDIO_CHANNEL_IN_MONO"/>
               

      
//这是一个名字为ble_audio的无线头戴式设备      /
   
                                                  samplingRates="16000"
                             channelMasks="AUDIO_CHANNEL_IN_MONO"/>
   
            
               
            


切换通路 需要结合dumpsys media.audio_policy中的HW Module去设置设备名称和类型


//选择头戴式设备输入
   mAudioManager.setWiredDeviceConnectionState(
AudioSystem.DEVICE_IN_WIRED_HEADSET, 1, "",
"ble_audio");
AudioSystem.setDeviceConnectionState(
AudioSystem.DEVICE_IN_BUILTIN_MIC, 1, "bottom",
"",AudioSystem.AUDIO_FORMAT_DEFAULT);

//取消选择头戴式设备输入
mAudioManager.setWiredDeviceConnectionState(
AudioSystem.DEVICE_IN_WIRED_HEADSET, 0, "",
"ble_audio");
AudioSystem.setDeviceConnectionState(
AudioSystem.DEVICE_IN_BUILTIN_MIC,0, "bottom",
"",AudioSystem.AUDIO_FORMAT_DEFAULT);

13.sendStickyBroadcast的作用和可能发生的情况
自己菜写了一个BUG出来，害得我多加了一个小时的班，这里记录一下


sendStickyBroadcast的作用是
只保留最后一条广播，并且一直保留下去，这样即使已经处理了这条广播但当再一次注册这条广播后依然可以收到它。
所以你注册多少次就可以收到多少次。
我在基类activity中写了一个abstract getViewmodel 方法子类继承的时候走了两次


      //mModel = getViewModel();
        if (getViewModel()!= null) {
            setViewModel(getViewModel()); //就这里viewmodel的初始化的时候会register receiver。。
             //然后就发现我收到了两个重复的广播
        }
        
     mModel = getViewModel();
        if (mModel!= null) {
            setViewModel(mModel);
        }
WifiManager.WIFI_STATE_CHANGED_ACTION 这个广播的发送是采用的
sendStickyBroadcastAsUser的 。所以才会有我收到两次的原因
12.记一次Anr log问题分析结局

9. KL映射关系
驱动定义键值位置… kernel/include/uapi/linux/input-event-codes.h


KEY         183                 F13
          底层键值            上层键值


8.生成系统签名的platform.jks
生成系统签名的platfrom.jks  vtechsz是密码 androiddebugkey 是alias
cp build/target/product/security/platform.pk8 ./temp
cp build/target/product/security/platform.x509.pem ./temp
cp prebuilts/sdk/tools/lib/signapk.jar ./temp
cp prebuilts/sdk/tools/linux/lib64/libconscrypt_openjdk_jni.so ./temp
cd ./temp
java -jar -Djava.library.path=.  signapk.jar platform.x509.pem platform.pk8 launcher.apk output.apk
openssl pkcs8 -inform DER -nocrypt -in platform.pk8 -out platform.pem
openssl pkcs12 -export -in platform.x509.pem -out platform.p12 -inkey platform.pem -password pass:vtechsz -name androiddebugkey
keytool -importkeystore -deststorepass vtechsz -destkeystore ./platform.jks -srckeystore ./platform.p12 -srcstoretype PKCS12 -srcstorepass vtechsz //密码需要和上面保持一致


7.电源键使用的GlobalAction.
使用的不是/policy/LegacyGlobalActions.java
而是


frameworks/base/packages/SystemUI/src/com/android/systemui/globalactions/GlobalActionsDialog.java
6.设置默认不休眠。
设置-1是莫的用的，注意overlay的使用
frameworks/base/packages/SettingsProvider/res/values/defaults.xml


2147483647
5.关机广播
    private void shutDown() {
        Intent shutDown = new Intent(Intent.ACTION_REQUEST_SHUTDOWN);
        shutDown.putExtra(Intent.EXTRA_KEY_CONFIRM, false);
        shutDown.putExtra(Intent.EXTRA_REASON, PowerManager.SHUTDOWN_REASON_SHUTDOWN);
        shutDown.putExtra(Intent.EXTRA_USER_REQUESTED_SHUTDOWN, false);
        shutDown.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
        mContext.startActivityAsUser(shutDown, UserHandle.CURRENT);
    }

4.预安装preinstall
把APK放到device/rockchip/rk3326/[project]/preinstall


preinstall是安装不可卸载   -->指向odm/bundled_persist-app          -->
preinstall_del是可以卸载 恢复出厂可以恢复  -->odm/bundled_uninstall_back-app
preinstall_del_forever是可卸载恢复出厂设置不可以恢复的  -->odm/bundled_uninstall_gone-app      


安装方式是在PKMS里面扫描进行installd安装的 预置到的目录是在Enviroments.java


里面有定义 PackageManagerService.java
new File(BUNDLED_PERSIST_DIR)
Environment.getPrebundledUninstallBackDirectory(),
Environment.getPrebundledUninstallGoneDirectory(),  扫描的是这三个目录


可能遇到的问题如下


1.APK未在相应的目录下安装生成




如果放入device/rockchip/rk3326/[project]/preinstall中没有生成对应的apk
请检测device/rockchip/rk3326/device-common.mk中
ifneq ($(strip $(TARGET_PRODUCT)), )
    #TARGET_DEVICE_DIR=$(shell test -d device && find device -maxdepth 4 -path '*/$(TARGET_PRODUCT)/BoardConfig.mk')
   #TARGET_DEVICE_DIR := $(patsubst %/,%,$(dir $(TARGET_DEVICE_DIR)))
    #$(info device-rockchip-common TARGET_DEVICE_DIR: $(TARGET_DEVICE_DIR))
    $(shell python $(LOCAL_PATH)/auto_generator.py $(TARGET_DEVICE_DIR) preinstall bundled_persist-app)
   $(shell python $(LOCAL_PATH)/auto_generator.py $(TARGET_DEVICE_DIR) preinstall_del bundled_uninstall_back-app)
    $(shell python $(LOCAL_PATH)/auto_generator.py $(TARGET_DEVICE_DIR) preinstall_del_forever bundled_uninstall_gone-app)
    -include $(TARGET_DEVICE_DIR)/preinstall/preinstall.mk
   -include $(TARGET_DEVICE_DIR)/preinstall_del/preinstall.mk
    -include $(TARGET_DEVICE_DIR)/preinstall_del_forever/preinstall.mk
endif
这段代码是否已被注释 ，如果注释，打开就行。TAGRGET_DEVICE_DIR没必要在打开。会报重复定义的错误


2.生成到img中了开机却无法自动安装


device/rockchip/common/sepolicy/vendor/system_server.te
+#add by tuliyuan
+#============= system_server ==============
+allow system_server vendor_file:dir { read open };
+allow system_server vendor_file:file { read open map getattr };


system/sepolicy/public/domain.te                  
   neverallow {
     coredomain
+    -system_server
     -appdomain
     -bootanim
     -crash_dump .... } vendor_file


system/sepolicy/prebuilts/api/29.0/public/domain.te 和上面的domain.te一样的
   neverallow {
     coredomain
+    -system_server
     -appdomain
     -bootanim
     -crash_dump .... } vendor_file


3。APK安装时使用的lib库明明符合系统架构却无法使用

1. RK3326分区
