Class CompatibilityInfo

  • All Implemented Interfaces:

    public class CompatibilityInfo
    extends Object
    implements Parcelable
    CompatibilityInfo class keeps the information about compatibility mode that the application is running under.
    • Field Detail


        public static final CompatibilityInfo DEFAULT_COMPATIBILITY_INFO
        default compatibility info object for compatible applications

        public static final int DEFAULT_NORMAL_SHORT_DIMENSION
        This is the number of pixels we would like to have along the short axis of an app that needs to run on a normal size screen.
        See Also:
        Constant Field Values

        public static final float MAXIMUM_ASPECT_RATIO
        This is the maximum aspect ratio we will allow while keeping applications in a compatible screen size.
        See Also:
        Constant Field Values
      • applicationDensity

        public final int applicationDensity
        The effective screen density we have selected for this application.
      • applicationScale

        public final float applicationScale
        Application's scale.
      • applicationInvertedScale

        public final float applicationInvertedScale
        Application's inverted scale.
    • Constructor Detail

      • CompatibilityInfo

        public CompatibilityInfo(ApplicationInfo appInfo,
                         int screenLayout,
                         int sw,
                         boolean forceCompat)
    • Method Detail

      • isScalingRequired

        public boolean isScalingRequired()
        true if the scaling is required
      • supportsScreen

        public boolean supportsScreen()
      • neverSupportsScreen

        public boolean neverSupportsScreen()
      • alwaysSupportsScreen

        public boolean alwaysSupportsScreen()
      • getTranslator

        public CompatibilityInfo.Translator getTranslator()
        Returns the translator which translates the coordinates in compatibility mode.
        params - the window's parameter
      • applyToDisplayMetrics

        public void applyToDisplayMetrics(DisplayMetrics inoutDm)
      • applyToConfiguration

        public void applyToConfiguration(int displayDensity,
                                Configuration inoutConfig)
      • computeCompatibleScaling

        public static float computeCompatibleScaling(DisplayMetrics dm,
                                     DisplayMetrics outDm)
        Compute the frame Rect for applications runs under compatibility mode.
        dm - the display metrics used to compute the frame size.
        orientation - the orientation of the screen.
        outRect - the output parameter which will contain the result.
        Returns the scaling factor for the window.
      • equals

        public boolean equals(Object o)
        Description copied from class: Object
        Compares this instance with the specified object and indicates if they are equal. In order to be equal, o must represent the same object as this instance using a class-specific comparison. The general contract is that this comparison should be reflexive, symmetric, and transitive. Also, no object reference other than null is equal to null.

        The default implementation returns true only if this == o. See Writing a correct equals method if you intend implementing your own equals method.

        The general contract for the equals and Object.hashCode() methods is that if equals returns true for any two objects, then hashCode() must return the same value for these objects. This means that subclasses of Object usually override either both methods or neither of them.

        equals in class Object
        o - the object to compare this instance with.
        true if the specified object is equal to this Object; false otherwise.
        See Also:
      • toString

        public String toString()
        Description copied from class: Object
        Returns a string containing a concise, human-readable description of this object. Subclasses are encouraged to override this method and provide an implementation that takes into account the object's type and data. The default implementation is equivalent to the following expression:
           getClass().getName() + '@' + Integer.toHexString(hashCode())

        See Writing a useful toString method if you intend implementing your own toString method.

        toString in class Object
        a printable representation of this object.
      • hashCode

        public int hashCode()
        Description copied from class: Object
        Returns an integer hash code for this object. By contract, any two objects for which Object.equals(java.lang.Object) returns true must return the same hash code value. This means that subclasses of Object usually override both methods or neither method.

        Note that hash values must not change over time unless information used in equals comparisons also changes.

        See Writing a correct hashCode method if you intend implementing your own hashCode method.

        hashCode in class Object
        this object's hash code.
        See Also:
      • describeContents

        public int describeContents()
        Description copied from interface: Parcelable
        Describe the kinds of special objects contained in this Parcelable's marshalled representation.
        Specified by:
        describeContents in interface Parcelable
        a bitmask indicating the set of special object types marshalled by the Parcelable.
