android - Jetpack 撰写新源无法正常工作
问题描述
我已经尝试使用旧的预构建源进行 Jetpack 组合。但最近我下载了一个新资源,但它对我不起作用。这是我尝试过的。
我在 Project/androidx_prebuilts/out/ui/build/support_repo/androidx 中添加了源
在 androidx 目录下,我有源代码的compose和ui目录
模块级gradle
apply plugin: 'com.android.application'

repositories {
maven { url "$androidx_home/out/ui/build/support_repo/" }

}

解决方案
首先,请参阅此文档:googlesource
“本节介绍如何设置本地工作环境来构建 Android 源文件。您必须使用 Linux 或 macOS;目前不支持在 Windows 下构建。” — 安卓文档
第1步:
首先,我们需要从(如果未安装) https://source.android.com/setup/build/downloading安装 Repo
并在命令行中点击以下命令
mkdir bin
PATH=~/bin:$PATH
curl https://storage.googleapis.com/git-repo-downloads/repo > ~/bin/repo
chmod a+x ~/bin/repo
现在检查repo status
第2步:
创建一个目录让我们说“AndroidCompose”
mkdir ~/AndroidCompose
cd ~/AndroidCompose
并设置 git config (如果没有设置)
git config — global user.name “Your Real Name”
git config — global user.email “you@example.com”
现在初始化回购
repo init -u https://android.googlesource.com/platform/manifest -b androidx-master-dev
存储库现在已初始化,如果我们查看 ~/AndroidCompose 目录,我们将看到一个“.repo”列表
打
ls -a ~/AndroidCompose/.repo
“现在您的存储库设置为仅提取构建和运行 AndroidX 库所需的内容。下载代码(在我们下载 6GB 时喝杯咖啡)”-Android Docs
第 3 步:获取所有必需源的命令
repo sync -j8 -c
(类似于 git fetch)
现在我们已经下载了正确版本的 Android JetPack 源代码,其中包含 @Composable
这会将所有 Jetpack Compose 源代码放在“ui”目录中
cd ~/AndroidCompose/frameworks/support/ui
打
./studiow
启动 Android 工作室
重新启动 Android Studio 时要小心。我们需要始终从该目录开始获取 Jetpack Compose 库。
出现提示时接受许可协议。现在我们已准备好编辑、运行和测试!
