Annotation Type Implements


@Documented @Retention(RUNTIME) @Target(TYPE) public @interface Implements
Indicates that a class declaration is intended to shadow an Android class declaration. The Robolectric runtime searches classes with this annotation for methods with the Implementation annotation and calls them in place of the methods on the Android class.

    Optional Element
    Description
    boolean
    If set to true, Robolectric will invoke the native method variant instead of the no-op variant.
    boolean
    If true, Robolectric will invoke the actual Android code for any method that isn't shadowed.
    Android class name (if the Class object is not accessible).
    boolean
    Denotes that this type exists in the public Android SDK.
    boolean
    If true, when an exact method signature match isn't found, Robolectric will look for a method with the same name but with all argument types replaced with java.lang.Object.
    int
    If specified, the shadow class will be applied only for this SDK or lesser.
    int
    If specified, the shadow class will be applied only for this SDK or greater.
    Class<? extends ShadowPicker<?>>
    If specified, the picker will be instantiated and called from within the newly-created Robolectric classloader.
    The Android class to be shadowed.
  • Element Details

    • value

      Class<?> value
      The Android class to be shadowed.
      Returns:
      Android class to shadow.
      Default:
      void.class
    • className

      String className
      Android class name (if the Class object is not accessible).
      Returns:
      Android class name.
      Default:
      ""
    • isInAndroidSdk

      boolean isInAndroidSdk
      Denotes that this type exists in the public Android SDK. When this value is true, the annotation processor will generate a shadowOf method.
      Returns:
      True if the type is exposed in the Android SDK.
      Default:
      true
    • callThroughByDefault

      boolean callThroughByDefault
      If true, Robolectric will invoke the actual Android code for any method that isn't shadowed.
      Returns:
      True to invoke the underlying method.
      Default:
      true
    • looseSignatures

      boolean looseSignatures
      If true, when an exact method signature match isn't found, Robolectric will look for a method with the same name but with all argument types replaced with java.lang.Object.
      Returns:
      True to disable strict signature matching.
      Default:
      false
    • minSdk

      int minSdk
      If specified, the shadow class will be applied only for this SDK or greater.
      Default:
      -1
    • maxSdk

      int maxSdk
      If specified, the shadow class will be applied only for this SDK or lesser.
      Default:
      -1
    • shadowPicker

      Class<? extends ShadowPicker<?>> shadowPicker
      If specified, the picker will be instantiated and called from within the newly-created Robolectric classloader. All shadow classes implementing the same Android class must use the same ShadowPicker.
      Default:
      org.robolectric.annotation.Implements.DefaultShadowPicker.class
    • callNativeMethodsByDefault

      boolean callNativeMethodsByDefault
      If set to true, Robolectric will invoke the native method variant instead of the no-op variant. This requires the native method to be bound, or an UnsatisfiedLinkError will occur.

      callNativeMethodsByDefault() has precedence over callThroughByDefault() For instance, if both callNativeMethodsByDefault() and callThroughByDefault() are true, the native method variant will be preferred over the no-op native variant.

      Default:
      false
