java - 在路径 DexPathList 上找不到类

Question

我试图将我的项目更新到 targetSdk 23，但鉴于所有的弃用，我决定我不适合它。我不想经历它，所以我在 mercurial 上恢复到旧版本，现在我得到的只是这个错误，我无法让该死的应用程序再次运行。可能出了什么问题？

Answer 1

Android application (APK) files contain executable bytecode files in the form of Dalvik Executable (DEX) files, which contain the compiled code used to run your app. The Dalvik Executable specification limits the total number of methods that can be referenced within a single DEX file to 65,536, including Android framework methods, library methods, and methods in your own code. Getting past this limit requires that you configure your app build process to generate more than one DEX file, known as a multidex configuration.

1. 更改 Gradle 构建配置以启用 multidex
2. 修改 list 以引用 MultiDexApplication 类

修改您的应用 Gradle 构建文件配置以包含支持库并启用 multidex 输出。

    android {
    compileSdkVersion 21
    buildToolsVersion "21.1.2"

    defaultConfig {
        ...
        minSdkVersion 14
        targetSdkVersion 21
        ...

        // Enabling multidex support.
        multiDexEnabled true
    }
    ...
}

dependencies {
  compile 'com.android.support:multidex:1.0.0'
}
