谷歌 6 月 17 日 Firebase SDK 更新后，Ionic Cordova 应用程序停止编译

问题描述

在 Firebase 主要版本更新后，我无法编译 Ionic Cordova 应用程序并进行重大更改，特别是 2019 年 6 月 17 日的更新.

I'm unable to compile Ionic Cordova App after Firebase Major version update with Breaking Changes, specifically with June 17, 2019 update.

我尝试降级到 Android Cordova 6.3.0，但我的项目必须是 7.0.0.

I tried downgrading to Android Cordova 6.3.0 but my project must be 7.0.0.

这是我的离子信息:

执行 aapt 失败

com.android.ide.common.process.ProcessException:执行失败适配

com.android.ide.common.process.ProcessException: Failed to execute aapt

推荐答案

此构建失败是由于 Google Play 服务和 Firebase 库的主要版本发布，于 6 月 17 日发布.

This build failure is due to a major version release of the Google Play Services and Firebase libaries on June 17.

新的库版本有以下要求:

The new library versions have the following requirements:

• 将 com.android.tools.build:gradle 升级到 v3.2.1 或更高版本.
• 将 compileSdkVersion 升级到 28 或更高版本.
• 更新您的应用以使用 Jetpack (AndroidX)

• Upgrade com.android.tools.build:gradle to v3.2.1 or later.
• Upgrade compileSdkVersion to 28 or later.
• Update your app to use Jetpack (AndroidX)

前两个要求可以通过更新为使用 cordova-android@8.0.0 来解决.

The first two requirements can be resolved by updating to use cordova-android@8.0.0.

第三个要求您的 Android 项目迁移到使用 AndroidX (Jetpack).AndroidX 是广泛使用的 Android 支持库.AndroidX 现在被最新版本的 Play Services/Firebase 库使用，而 Support 库被许多现有插件使用，例如 cordova-plugin-firebase.这两个库不能同时存在于同一个 Android 构建中 - 这样做会导致构建失败.

The third requires that your Android project migrates to using AndroidX (Jetpack). AndroidX is the successor to the widely-used Android Support Library. AndroidX now used by the latest versions of Play Services/Firebase libraries and the Support library is used by many existing plugins such as cordova-plugin-firebase. The two libraries cannot live side-by-side in the same Android build - doing so will lead to build failure.

要解决此问题，请在您的 Cordova 项目中添加以下两个插件:

To resolve this issue, add the following two plugins your Cordova project:

• cordova-plugin-androidx 在 Android 项目中启用 AndroidX.
• cordova-plugin-androidx-adapter 动态修补源码任何使用支持库以使用 AndroidX 等效项的插件.

• cordova-plugin-androidx to enable AndroidX in the Android project.
• cordova-plugin-androidx-adapter to dynamically patch the source code of any plugins using the Support Library to use the AndroidX equivalents.

有关如何在测试项目中试用此功能的工作示例，请参阅 我对这个 Github 问题的评论.

For a working example of how to try this out in a test project, see my comment on this Github issue.

注意:如果您使用的是 cordova-plugin-firebase 并遇到错误，您可以改用 my fork of that plugin 发布为cordova-plugin-firebasex 并已修复以解决新 Firebase SDK 引起的问题:

Note: if you are using cordova-plugin-firebase and encountering errors, you can instead use my fork of that plugin which is published as cordova-plugin-firebasex and is fixed to resolve issues caused by the new Firebase SDK:

rm -Rf platforms/android
cordova plugin rm cordova-plugin-firebase
rm -Rf plugins/ node_modules/
npm install
cordova plugin add cordova-plugin-firebasex
cordova platform add android
