Error converting bytecode to dex: Cause: com.android.dex.DexException:Multiple dex files define Landroid/arch/lifecycle/liveData$1;

Answer 1

I've just met the same issue and fixed it by updating the version of lifecycle library:

implementation 'android.arch.lifecycle:runtime:1.1.0'
implementation 'android.arch.lifecycle:extensions:1.1.0'
implementation 'android.arch.lifecycle:compiler:1.1.0'

It seems that another library using in my project declare the version 1.1.0, but i was using 1.0.0.

Answer 2

Do you have the latest multidex in your gradle dependencies ?

'com.android.support:multidex:1.0.1'

and add this

android {
    dexOptions {
        preDexLibraries = false
    }
}

Answer 3

This should be related to incompatible versions in your gradle library. can you past your gradle libraries here

Answer 4

尝试“文件”菜单下的“无效缓存/重新启动...”菜单。

Answer 5

遇到了同样的问题，我所要做的就是将我使用的所有库更新为各自的新更新并同步 gradle并重新构建并再次运行这对我有用

Answer 6

I updated libraries with new version. Need to declare all the android base libraries in the same version(If you update some libraries with new version and using some in older one will cause this kind of exception).

    ext { archLifecycleVersion = '1.1.0'}

dependencies {
implementation "android.arch.lifecycle:extensions:$rootProject.archLifecycleVersion"
annotationProcessor "android.arch.lifecycle:compiler:$rootProject.archLifecycleVersion"}

Answer 7

您是否在 build.gradle 中添加了依赖项？

compile 'com.android.support:multidex:1.0.0'
