E/LoadedApk:无法仅在 Android Q (API 29) 上实例化 appComponentFactory [英] E/LoadedApk: Unable to instantiate appComponentFactory only on Android Q (API 29)
问题描述
我已经到处搜索了，但仍然没有解决方案.
I have searched everywhere about this and still have no solution.
gradle 有 minSdkVersion 21 和 targetSdkVersion 29
The gradle has minSdkVersion 21 and targetSdkVersion 29
我只在 API 29 中遇到错误，然后应用程序无法加载并显示空白屏幕.当我看到 logcat 时，它给出了这样的错误:
I got error only in API 29, then the app doesn't load and show up blank screen. When i see logcat it gives an error like this :
E/LoadedApk: Unable to instantiate appComponentFactory
java.lang.ClassNotFoundException: Didn't find class "androidx.core.app.CoreComponentFactory" on path: DexPathList[[],nativeLibraryDirectories=[/data/app/com.packagename.appname-BxS7Zs-h0IWwJAVhbjx7aQ==/lib/x86, /data/app/com.packagename.appname-BxS7Zs-h0IWwJAVhbjx7aQ==/base.apk!/lib/x86, /system/lib, /system/product/lib]]

我认为它似乎来自 multidex，然后我尝试将以下代码添加到 gradle 应用程序
I think it seems like from multidex, then i have tried adding following code to gradle app
multiDexKeepFile 文件('multidex-config.txt')
multiDexKeepFile file('multidex-config.txt')
multiDexKeepProguard 文件('multidex-config.pro')
multiDexKeepProguard file('multidex-config.pro')
我的 multidex-config.txt
my multidex-config.txt

我的 multidex-config.pro
my multidex-config.pro
-keep class androidx.core.app.CoreComponentFactory { *; }
我的 App 类扩展 MultiDexApplication
my App class extending MultiDexApplication
public class App extends MultiDexApplication {
@Override
protected void attachBaseContext(Context base) {
super.attachBaseContext(base);
MultiDex.install(this);
}
}

推荐答案
错误是指向使用 androidx CoreComponentFactory 类(使用 AndroidX) 但你正在使用旧包 com.android.support:multidex
The error is pointing to the use of androidx CoreComponentFactory class(using AndroidX) but you are using old package com.android.support:multidex
所以使用 androidx 依赖为:
implementation 'androidx.multidex:multidex:2.0.1'
代替
implementation 'com.android.support:multidex:2.0.1'
并确保在应用程序类中使用 androidx 导入
and make sure to use androidx imports in the application class as
import android.content.Context;
import androidx.multidex.MultiDex;
import androidx.multidex.MultiDexApplication;
public class YourApp extends MultiDexApplication {
@Override
protected void attachBaseContext(Context base) {
MultiDex.install(this);
super.attachBaseContext(base);
}
}
此外:在应用加载期间，无论您是否在清单中使用 CoreComponentFactory 实例，android Q 都会在内部使用它，这会导致问题.
Additionally: During the app Load-up, android Q uses the CoreComponentFactory instance internally whether you are using it in manifest or not, which is causing the issue.
另外，添加 multiDexEnabled true 作为 defaultConfig{multiDexEnabled true }
更新: 在 RCA 之后，componentfactory 导入问题已通过 androidx 库导入解决，尽管 facebook sdk 存在另一个问题版本 4.36.0 中的依赖项已通过将版本降级到 4.35.0(或使用最新版本集成)解决，并且还发布了 此处.
Update: After the RCA, the componentfactory import issue was resolved with the androidx lib imports though there was another issue with the facebook sdk dependency in version 4.36.0 which was resolved by downgrading the version to 4.35.0(or use latest version integration) and also posted here.
