标签: android-multidex

我有一个用 react native 构建的应用程序，我需要启用MultiDex支持。我的问题是我无法导入MultiDexApplication类来扩展它，因为在编译时我在扩展它时同时获得symbol not found error了导入语句和类名MainApplication.java

build.gradle

    dependencies {
        classpath('com.android.tools.build:gradle:3.5.3')
        classpath 'com.google.gms:google-services:4.2.0'
        classpath "androidx.multidex:multidex:2.0.1"

    }

如果我尝试将依赖项添加为实现，则在启动应用程序时会出现以下错误：

Could not find method implementation() for arguments [androidx.multidex:multidex:2.0.1] on object of type org.gradle.api.internal.artifacts.dsl.dependencies.DefaultDependencyHandler.

在所有在线资源中，我看到依赖项是作为实现添加的，所以我想这可能是我的问题。

MainApplication.java

package com.classmanager;

import android.app.Application;
import androidx.multidex.MultiDexApplication;
import android.content.Context;
import com.facebook.react.PackageList;
import com.facebook.react.ReactApplication;

import java.lang.reflect.InvocationTargetException;
import java.util.List;

public class MainApplication extends MultiDexApplication  implements ReactApplication {
  private final ReactNativeHost mReactNativeHost =
      new ReactNativeHost(this) …

我正在使用鲍雷提供的代码，名称为private fun saveImage在如何将位图保存到 android gallery来保存位图

为了解决 Kotlin 中已弃用的问题，我删除了这些行：

 //values.put(MediaStore.Images.Media.DATA, file.absolutePath) 
//context.contentResolver.insert(MediaStore.Images.Media.EXTERNAL_CONTENT_URI, values)

并添加了这个：

 val contentValues = ContentValues()

 contentValues.put(MediaStore.Images.Media.RELATIVE_PATH, folderName)

 this.applicationContext.contentResolver.insert(MediaStore.Downloads.EXTERNAL_CONTENT_URI, contentValues)

然后，我将该函数（在 DidtodayActivity 中）称为：

saveImage(bitmapImg, this.applicationContext)

图像被下载到Phone>Android>Data>com.example.MyApp1>files>MyFiles。我可以在我的设备中看到下载的图像。

但是，由于这一行的运行时错误，活动文件突然关闭（并且直接打开activity_main .xml）：

this.applicationContext.contentResolver.insert(MediaStore.Downloads.EXTERNAL_CONTENT_URI, contentValues)

原因：

java.lang.ClassNotFoundException: Didn't find class "android.provider.MediaStore$Downloads" on path: DexPathList[[zip file "/data/app/com.example.MyApp1-rvQQjSAj4NilLch2h12faQ==/base.apk"],nativeLibraryDirectories=[/data/app/com.example.MyApp1-rvQQjSAj4NilLch2h12faQ==/lib/arm64, /data/app/com.example.MyApp1-rvQQjSAj4NilLch2h12faQ==/base.apk!/lib/arm64-v8a, /system/lib64]]

详细信息：

**Didn't find class "android.provider.MediaStore$Downloads"** on path: DexPathList[[zip file "/data/app/com.example.MyApp1-rvQQjSAj4NilLch2h12faQ==/base.apk"],nativeLibraryDirectories=[/data/app/com.example.MyApp1-rvQQjSAj4NilLch2h12faQ==/lib/arm64, /data/app/com.example.MyApp1-rvQQjSAj4NilLch2h12faQ==/base.apk!/lib/arm64-v8a, /system/lib64]]

如果我使用Ionic Framework构建应用程序,有没有办法为Android 设置启用multidex(https://github.com/casidiablo/multidex)？

有人知道为什么我不能使用MultiDexTestRunner吗？

我的build.gradle包含:

    defaultConfig {

我下载了SugarORM源代码以将其用作库模块(因此我可以覆盖应用程序的"attachBaseContext"方法.

我已经看到了SugarORM和multidex的问题,问题是我无法弄清楚如何将MultiDex库引用到我的新SugarORM库模块中.有人可以帮我解决这个问题吗？

我试图在API 16设备上运行需要使用Android Studio 3.0的MultiDex的应用程序,当应用程序最终尝试启动时,它会崩溃.其他低API也是如此(例如:17,18,19)

但是,当我尝试使用Android Studio 3.1(测试版)运行应用程序时,不会发生崩溃.

这种崩溃有什么办法可以修复吗？
