WorkManager1.0.0-alpha02 から 1.0.0-alpha03にアップグレードしたとき。
古い build.gradle
def work_version = "1.0.0-alpha02"
implementation "android.arch.work:work-runtime:$work_version" // use -ktx for Kotlin
// optional - Firebase JobDispatcher support
implementation "android.arch.work:work-firebase:$work_version"
新しい build.gradle
def work_version = "1.0.0-alpha03"
implementation "android.arch.work:work-runtime:$work_version" // use -ktx for Kotlin
// optional - Firebase JobDispatcher support
implementation "android.arch.work:work-firebase:$work_version"
次の変更を加える必要があることに気付きました
1.0.0-alpha02
public WorkerResult doWork() {
1.0.0-alpha03
public Result doWork() {
しかし、それは大きな問題ではありません。ただし、以前に を使用して既に実行されているアプリをアップグレードする傾向がある場合1.0.0-alpha02、次のランタイム例外が発生します。

このような実行時例外を回避するための回避策を教えてください。
