MacBook m2芯片电脑安装哪个版本的Android studio
说明:Mac上选择Android studio需要选择带arm的版本。不然会安装不起来。
具体版本见前面“Android Studio安装”。
android studio默认安装路径Mac
- 本机安装地址为:
/Users/hh/Library/Application Support/Google/AndroidStudio2020.3
Android studio升级问题
-
AS启动之后,一般会有如下弹框,
如果不幸点了上面的Gradle升级弹框,没出问题则罢,出了问题大概率情况需要重新安装Android studio。
注意:重装AS前,最好清理掉如下3个位置:
1)AS安装目录
比如Mac上目录如下:
/Applications/Android Studio.app
2)AS下载的SDK目录
比如Mac目录如下(这是自定义目录,根据安装时目录具体找):
/Users/hh/Documents/android/sdk
3)gradle所在目录
比如Mac上目录如下:
/Users/hh/.gradle
Gradle sync失败

2021-11-24 20:03:56,534 [2025237] ERROR - intellij.openapi.progress.Task - Module: 'app' platform 'android-29' not found.
处理:
缺少platform 'android-29',从setting->sdk 中下载platform 'android-29',重新同步。参考:

AS(Android Studio)显示工具栏步骤:
- 主要使用点击到回到上一页/下一页功能。
- 结论:
View -- Appearance -- Toolbar 打上勾就会显示了。
build.gradle配置
gradle清理缓存
- 强制清除gradle 缓存/Mac gradle清理缓存
Windows:
gradlew build --refresh-dependencies
Mac:
./gradlew build --refresh-dependencies
- Mac如果遇到如下问题:
zsh: no such file or directory: ./gradlew
处理:最简单的方式就是终端执行cd命令到gradlew下(每个Android工程都有该工具),然后再执行上述命令。

- 说明:如果targetSdkVersion设置31或以上,则需要适配Android 12,看资料可知需要将工程中AndroidManifest.xml所有exported的地方设置为true,包括引入的库也需要做适配(比如在app下的build.gradl做配置,具体见如下参考)。如果工程不对这个做要求,可以降低targetSdkVersion版本(低于31)即可。

api project(':imsdk-plus')
} else {
api 'com.tencent.imsdk:imsdk-plus:6.3.2609'
}

http://t.zoukankan.com/morlin-p-4647447.html
https://www.jb51.cc/mac/2923682.html说明:Android Studio自带的JDK没法用,只好额外安装JDK。
安装了JDK18:
java version "18.0.2.1" 2022-08-18
Java(TM) SE Runtime Environment (build 18.0.2.1+1-1)
Java HotSpot(TM) 64-Bit Server VM (build 18.0.2.1+1-1, mixed mode, sharing)
通过keytool命令:
keytool -list -v -keystore + keystore的绝对路径
能够拿到证书指纹,包括SHA1和SHA256,但是获取不到MD5.
解决:需要降低JDK版本,比如安装Java7就可以获取到MD5.
