Google在6月17日更新Firebase SDK后，Ionic Cordova应用程序停止了编译

Question

在Firebase主要版本更新后，尤其是2019年6月17日更新之后，我无法编译Ionic Cordova App。

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

这是我的离子信息：

@ionic/cli-utils  : 1.19.2
    ionic (Ionic CLI) : 3.20.0

global packages:

    cordova (Cordova CLI) : 8.0.0

local packages:

    @ionic/app-scripts : 3.2.1
    Cordova Platforms  : android 7.0.0 browser 5.0.4
    Ionic Framework    : ionic-angular 3.9.3

System:

    Android SDK Tools : 26.1.1
    Node              : v8.9.1
    npm               : 5.5.1
    OS                : Windows 10

Environment Variables:

    ANDROID_HOME : C:\Development\android-sdk

Misc:

    backend : pro

这是我得到的错误：

无法执行Aapt

Answer 1

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

The new library versions have the following requirements:

• 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)

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

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.

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

• 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.

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

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

1.第一个答案

我们已经为此https://github.com/wizpanda/cordova-plugin-firebase-lib/pull/13创建了PR，但这需要升级cordova-android到8.0.0。

一种解决方法正在针对cordova-android7.x 进行，但与此同时，有关是否继续为其提供支持的讨论也在进行中。

2.编辑-2019年6月19日

已发布新版本的v3.3.0，以修复由支持的Google Firebase版本引起的问题cordova-android <= 7.1.4。https://github.com/wizpanda/cordova-plugin-firebase-lib/pull/14#issuecomment-503499409

cordova plugin remove cordova-plugin-firebase-lib
# Or if you were using original fork
#cordova plugin remove cordova-plugin-firebase
cordova plugin add cordova-plugin-firebase-lib@3.3.0

3.编辑-2019年6月20日

已发布新版本v4.0.1，以修复由支持的Google Firebase版本引起的问题cordova-android >= 8.0.0。https://github.com/wizpanda/cordova-plugin-firebase-lib/pull/14#issuecomment-503499409

cordova plugin remove cordova-plugin-firebase-lib
# Or if you were using original fork
#cordova plugin remove cordova-plugin-firebase
cordova plugin add cordova-plugin-firebase-lib

Answer 3

在platform / android / project.properties中具有以下设置：

cordova.gradle.include.1=cordova-plugin-firebase/app-build.gradle
cordova.system.library.4=com.google.firebase:firebase-core:+
cordova.system.library.5=com.google.firebase:firebase-messaging:+
cordova.system.library.6=com.google.firebase:firebase-config:+
cordova.system.library.7=com.google.firebase:firebase-perf:+

我遇到了同样的问题（错误：找不到资源android：attr / ttcIndex）。

cordova-android@8.0.0 + cordova-plugin-androidx + cordova-plugin-androidx-adapter非常适合我。

感谢您的解决方案。

我只是想知道使用这两个插件是否是一个好时机。有什么意见吗？

Answer 4

按照以下顺序进行cordova-android <= 7.1.4

cordova平台删除android
cordova插件删除cordova-plugin-
firebase
cordova 插件添加cordova-plugin-firebase-lib@3.3.0 cordova平台添加android

cordova-plugin-firebase-lib现在包含了cordova-plugin-firebase
