我正在修改我的应用程序，当我再次运行它时，它给了我一个大错误，我不认为这是我的代码，因为我的代码没有错误，但我认为这是由于依赖关系而导致的错误(我希望)
但我最好问一下，以免破坏应用程序并且问题更大
这是它抛出的错误:

> Task :app:mergeDexDebug
AGPBI: {"kind":"error","text":"Cannot fit requested classes in a single dex file (# methods: 66078 > 65536)","sources":[{}],"tool":"D8"}
com.android.builder.dexing.DexArchiveMergerException: Error while merging dex archives:

Answer 1

您需要对您的应用程序进行多重索引，因为您超过了 64K 限制。
添加方法如下:
在应用级 build.gradle 中:

android {
    defaultConfig {
        ...
        multiDexEnabled true
    }
}

dependencies {
  implementation 'com.android.support:multidex:1.0.3'
}
