.dex 文件中方法引用的数量不能超过 64k API 17 [英] The number of method references in a .dex file cannot exceed 64k API 17

问题描述

我正在使用 SugarORM 库构建一个应用程序，但是当我尝试为 API 17 构建项目时(没有检查其他项目)，它显示构建错误.

I am building an app with SugarORM Library but when I try to build the project for API 17 (didn't check for others) it shows build error.

但是当我为 android v5.0 或更高版本构建这个项目时，它工作正常.如果我删除 SugarORM gradle 依赖项，它在 v4.2.2 和 v5.0 设备上都可以正常工作.

But when I build this project for android v5.0 or above, it works fine. If I remove SugarORM gradle dependency it works fine for both devices v4.2.2 and v5.0.

推荐答案

你的方法太多了.dex 只能有65536 个方法.

You have too many methods. There can only be 65536 methods for dex.

建议您可以使用 multidex 支持.

As suggested you can use the multidex support.

只需在 module/build.gradle 中添加这些行:

Just add these lines in the module/build.gradle:

android {
   
    defaultConfig {
        ...
        
        // Enabling multidex support.
        multiDexEnabled true
    }
    ...
}

dependencies {
  implementation 'androidx.multidex:multidex:2.0.1'  //with androidx libraries
  //implementation 'com.android.support:multidex:1.0.3'  //with support libraries
  
}

也在你的 Manifest 中添加 MultiDexApplication 类从 multidex 支持库到应用程序元素

Also in your Manifest add the MultiDexApplication class from the multidex support library to the application element

    <?xml version="1.0" encoding="utf-8"?>
    <manifest xmlns:android="http://schemas.android.com/apk/res/android"
        package="com.example.android.multidex.myapplication">
        <application
            ...
            android:name="androidx.multidex.MultiDexApplication">

            <!-- If you are using support libraries use android:name="android.support.multidex.MultiDexApplication" -->

            <!--If you are using your own custom Application class then extend -->
            <!--MultiDexApplication and change above line as-->
            <!--android:name=".YourCustomApplicationClass"> -->

            ...
        </application>
    </manifest>

如果您使用自己的 Application 类，请将父类从 Application 更改为 MultiDexApplication.
如果你不能这样做，在你的应用程序类中覆盖 attachBaseContext 方法:

If you are using your own Application class, change the parent class from Application to MultiDexApplication.
If you can't do it, in your Application class override the attachBaseContext method with:

@Override
protected void attachBaseContext(Context newBase) {
    super.attachBaseContext(newBase);
    MultiDex.install(this);
}

另一种解决方案是尝试使用 ProGuard 删除未使用的代码 - 配置 ProGuard 设置，让您的应用运行 ProGuard 并确保您为发布版本启用了收缩.

Another solution is to try to remove unused code with ProGuard - Configure the ProGuard settings for your app to run ProGuard and ensure you have shrinking enabled for release builds.
