android - Gradle - 意外的顶级异常 - 无处不在

Question

相当确定 gradle 适合我。几天前启动了一个运行良好的项目。更新了android studio，再次打开项目。我已经尝试了所有我能想到的方法，从删除/更新检查 xml 文件和结构的库。删除 gradle 缓存并安装最新的 jdk，这里似乎没有任何帮助。

还尝试添加:

configurations {
    all*.exclude group: 'com.android.support', module: 'support-v4'
}

在 stackoverflow 上的其他帖子中提到

我从控制台导出了错误，它看起来像这样:

objc[2338]: Class JavaLaunchHelper is implemented in both /Library/Java/JavaVirtualMachines/jdk1.8.0_05.jdk/Contents/Home/bin/java and /Library/Java/JavaVirtualMachines/jdk1.8.0_05.jdk/Contents/Home/jre/lib/libinstrument.dylib. One of the two will be used. Which one is undefined.

Answer 1

你的问题:你已经通过了大约。编译应用程序时有 65000 个方法限制。您必须找到一种方法来减少应用中的方法数量。

如果您使用的是 Google Play 服务，您可以尝试 this method以更细粒度地编译它。

如果没有，您可以简单地使用 multiDex(确保您使用的是最新版本的 Android Studio)。在您的 build.gradle 文件中使用它:

android {
    defaultConfig {
        ...
        multiDexEnabled = true
    }
}
