Android工程中方法数超过65536解决方法(Kotlin)

Android Studio报错：

The number of method references in a .dex file cannot exceed 64K. Caused by: com.android.tools.r8.utils.AbortException: Error: Cannot fit requested classes in a single dex file (# methods: 68815 > 65536)

解决方案

1. build.gradle文件android的defaultConfig里面增加multiDexEnabled true
2. build.gradle文件dependencies里面增加implementation 'com.android.support:multidex:1.0.3'
3. Application类中增加

• kotlin写法

    override fun attachBaseContext(base: Context) {
        super.attachBaseContext(base)
        MultiDex.install(this)
    }

• java写法

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