FAQ：

1、hdc push so一直提示只读？

hdc shell进去后输入 mount -o rw,remount / 然后退出再传试试

2、hap包push到手机不生效？

file send 不会替换原来已经存在的hap包，手动先删掉设备中的hap包试试  -- 20210908

3、DevEco里面config.json修改后不生效？

config.json里面改了以后，直接构建的hap没有更新，先clean一下再构建试试

4、修改so步骤举例

1）编译：

./build.sh --product-name Hi3516DV300 --build-target notification

2）cp  out/ohos-arm-release/notification/ans_standard//libnotification.z.so ~/hgfs/

3）CMD窗口：

hdc shell "mount -o rw,remount /"

hdc file send D:\renchunyang\vmwareShare\libnotification.z.so /system/lib/module/libnotification.z.so

hdc shell "reboot"

5、重新安装应用举例：

hdc shell "bm uninstall -n ohos.samples.jshelloworld"

hdc shell "mount -o rw,remount /"

hdc file send D:\renchunyang\workspace\devEco\JsHelloWorld\entry\build\outputs\hap\debug\entry-debug-standard-signed.hap /derek.hap

hdc shell "chmod 666 /derek.hap"

hdc shell "bm install -p /derek.hap"

应用2：

hdc shell "bm uninstall -n com.example.myapplication"
hdc shell "mount -o rw,remount /"
hdc file send D:\renchunyang\workspace\devEco\MyApplication2\entry\build\outputs\hap\debug\entry-debug-standard-ark-signed.hap /application2.hap
hdc shell "chmod 666 /application2.hap"
hdc shell "bm install -p /application2.hap"

• 日志打印不全时，通过创建文件来调试：

#include <iostream>
#include <fstream>
#include <streambuf>

void ReminderDataManager::CreateFile(const std::string &path, const std::string &content) const
{
    ANSR_LOGD("Path=%{public}s", path.c_str());
    std::ofstream stream(path.c_str());
    if (!stream.is_open()) {
        ANSR_LOGE("Can not create file");
        return;
    }
    stream << content.c_str() << std::endl;
    stream.close();
    return;
}

#include <fstream>
#include <iostream>

std::string result
        = std::to_string(data->resType) + ", " + std::to_string(data->value) + "," + data->payload.toStyledString();
    WriteToFile(result);

void DevSchedPlugin::WriteToFile(std::string &result) const
{
    std::ofstream fout;
    std::string realPath = "/data/service/el1/public/dev_sched_test";
    fout.open(realPath, std::ios::app);
    fout<<result.c_str()<<std::endl;
    fout.close();
}

hdc shell "hilog -b X"  // 关闭所有子系统的日志

// 打开指定TAG的日志，多次输入不同的值可以指定多个
hdc shell "hilog -b D -D 0xD001700" 
hdc shell "hilog -b D -T RSS"

如果想重启也生效，需要修改/etc/param/hilog.para文件：

hilog.loggable.global=X    -->  改为X
hilog.loggable.domain.d001700=D    --> 指定需要打开的域
hilog.loggable.tag.RSS=D   --> 指定需要打开的tag
