Android的架構組件與API 14

我嘗試使用Android的體系結構組件，其做工精細的API 21+ 但在API 14：Android的架構組件與API 14

Dependensies

dependencies { 
    implementation fileTree(include: ['*.jar'], dir: 'libs') 
    implementation "org.jetbrains.kotlin:kotlin-stdlib-jre7:$kotlin_version" 
    implementation 'com.android.support:appcompat-v7:26.+' 
    implementation 'com.android.support.constraint:constraint-layout:+' 
    compile 'com.android.support:recyclerview-v7:26.+' 
    compile 'android.arch.lifecycle:runtime:+' 
    compile 'android.arch.lifecycle:extensions:+' 
    annotationProcessor "android.arch.lifecycle:compiler:+" 
    implementation 'com.android.support:support-v4:26.+' 
}

有什麼辦法要解決這個問題？

看看這個問題。可能與您的問題有關https://stackoverflow.com/questions/44075089/noclassdeffounderror-landroid-arch-lifecycle-lifecycledispatcher – Neil

是的，我看到了您的解決方案，但對我來說它不起作用 – Hagakurje

不是我的解決方案，只是看到回答並認爲它可能有所幫助。 – Neil

由於1.0.0-alpha4大部分arch prouard問題應該修復。你需要ProGuard的文件中做的唯一增加的是下面的規則，如果你想使用房間：

-dontwarn android.arch.persistence.room.paging.LimitOffsetDataSource

原來的答覆：

您是否嘗試過使用這些規則解決你的問題？適用於我。

# LifecycleObserver's empty constructor is considered to be unused by proguard 
-keep class * implements android.arch.lifecycle.LifecycleObserver { 
    <init>(...); 
} 
# ViewModel's empty constructor is considered to be unused by proguard 
-keepclassmembers class * extends android.arch.lifecycle.ViewModel { 
    <init>(...); 
} 
# keep Lifecycle State and Event enums values 
-keepclassmembers class android.arch.lifecycle.Lifecycle$State { *; } 
-keepclassmembers class android.arch.lifecycle.Lifecycle$Event { *; } 
# keep methods annotated with @OnLifecycleEvent even if they seem to be unused 
# (Mostly for LiveData.LifecycleBoundObserver.onStateChange(), but who knows) 
-keepclassmembers class * { 
    @android.arch.lifecycle.OnLifecycleEvent *; 
}
