sdkman

安装groovy

Simply open a new terminal and enter:
$ curl -s get.sdkman.io | bash
Follow the instructions on-screen to complete installation.
Open a new terminal or type the command:
$ source “$HOME/.sdkman/bin/sdkman-init.sh”
Then install the latest stable Groovy:
$ sdk install groovy
After installation is complete and you’ve made it your default version, test it with:
$ groovy -version
That’s all there is to it!

配置路径使idea容易找到

sudo ln -s /usr/local/opt/groovy/libexec /Library/Groovy

安装目录

所有sdk都安装在了sdkman目录下：~/.sdkman/candidates/

Mac系统如何显示隐藏文件？

Command+Shift+. 可以显示隐藏文件、文件夹，再按一次，恢复隐藏；

Linux/Mac下统计当前文件夹下的文件个数、目录个数

1.统计当前文件夹下文件的个数

ls -l |grep "^-"|wc -l

2、 统计当前文件夹下目录的个数

ls -l |grep "^d"|wc -l

3、 统计当前文件夹下文件的个数，包括子文件夹里的

ls -lR|grep "^-"|wc -l

4、统计文件夹下目录的个数，包括子文件夹里的

ls -lR|grep "^d"|wc -l

5、 说明

代码如下:

ls -l

长列表输出当前文件夹下文件信息(注意这里的文件，不同于一般的文件，可能是目录、链接、设备文件等)

代码如下:

grep "^-"

这里将长列表输出信息过滤一部分，只保留一般文件，如果只保留目录就是 ^d
代码如下:

wc -l

统计输出信息的行数，因为已经过滤得只剩一般文件了，所以统计结果就是一般文件信息的行数，又由于一行信息对应一个文件，所以也就是文件的个数。

adb backup

1.备份：adb backup -f /Users/xxx/Desktop/photo/clientbackup.ab 包名
2.Android backup extractor
下载abe.jar
执行： java -jar /Users/xxx/Desktop/photo/abe.jar unpack /Users/xxx/Desktop/photo/clientbackup.ab /Users/xxx/Desktop/photo/clientbackup.tar
3.恢复：adb restore clientbackup.ab

adb多用户操作

查看用户列表

adb shell pm list users

创建新用户

adb shell pm create-user [–profileOf USER_ID] [–managed] USER_NAME

adb shell pm create-user 10 godv

启动和切换用户

adb shell am switch-user USER_ID

adb shell am start-user USER_ID

安装应用到某个用户下

adb install –user USER_ID name.apk

删除用户

adb shell pm remove-user USER_ID

为了多用户下的数据安全性，在每个新用户创建之初，不管是外部存储（External Storage）还是app data目录，Android都为其准备了独立的文件存储

/storage/emulated/下拥有不同的用户分区

/storage/emulated/0

/storage/emulated/10

     uid = (int) m.invoke(null);
     } catch (Exception e) {
         e.printStackTrace();
   }

ContentResolver下的uri

content:// USER_ID @media/external/audio/media

即可获取不同用户下的不同数据

chenyudeMacBook-Pro:~ chenyu$ open .bash_profile

chenyudeMacBook-Pro:~ chenyu$ source .bash_profile

自动设置：

export PATH=$PATH:/Users/chenyulong01/gradle/gradle-7.3/bin

chenyudeMacBook-Pro:Robot chenyu$ npm config set strict-ssl false

nps穿透

安装

$ cd /opt/nps

$ ./nps install -config=/etc/nps/nps.conf

启动

$ sudo nps start

其他命令

停止

$ sudo nps stop

客户端更新

$ sudo nps-update update

修改配置

如果需要更换命令内容需要先卸载./nps uninstall，再重新安装

$ cd /opt/nps

$ ./nps uninstall

成功后再重新安装

$ ./nps install -config=/etc/nps/nps.conf

linux卸载nps,CentOS安装nps

Android Studio 不能调试

提示异常：Attention! No symbol directories found - please check your native debug configuration

解决方案：在Android studio， file–>settering—>plugins—-android NDK support插件的选项去掉。重新编译后再debug就可以了。

Execution failed for JetifyTransform

Suggestions:
            - If you believe this library doesn't need to be jetified (e.g., if it already supports AndroidX, or if it doesn't use support libraries/AndroidX at all), add android.jetifier.blacklist = {<!-- -->comma-separated list of regular expressions (or simply names) of the libraries that you don't want to be jetified} to the gradle.properties file.
            - If you believe this library needs to be jetified (e.g., if it uses old support libraries and breaks your app if it isn't jetified), contact the library's authors to update this library to support AndroidX and use the supported version once it is released.

解决方案：在gradle.properties配置文件中添加，android.jetifier.blacklist = common-27.1.0.jar,bundletool-0.14.0.jar
