InstallConstraints

class InstallConstraints : Parcelable
kotlin.Any
   ↳ android.content.pm.PackageInstaller.InstallConstraints

A class to encapsulate constraints for installation. When used with checkInstallConstraints(java.util.List,android.content.pm.PackageInstaller.InstallConstraints,java.util.concurrent.Executor,java.util.function.Consumer), it specifies the conditions to check against for the packages in question. This can be used by app stores to deliver auto updates without disrupting the user experience (referred as gentle update) - for example, an app store might hold off updates when it find out the app to update is interacting with the user. Use Builder to create a new instance and call mutator methods to add constraints. If no mutators were called, default constraints will be generated which implies no constraints. It is recommended to use preset constraints which are useful in most cases. For the purpose of gentle update, it is recommended to always use GENTLE_UPDATE for the system knows best how to do it. It will also benefits the installer as the platform evolves and add more constraints to improve the accuracy and efficiency of gentle update. Note the constraints are applied transitively. If app Foo is used by app Bar (via shared library or bounded service), the constraints will also be applied to Bar.

Public methods

describeContents

Added in API level 34
fun describeContents(): Int

Describe the kinds of special objects contained in this Parcelable instance's marshaled representation. For example, if the object will include a file descriptor in the output of writeToParcel(android.os.Parcel,int), the return value of this method must include the CONTENTS_FILE_DESCRIPTOR bit.

Return
Int a bitmask indicating the set of special object types marshaled by this Parcelable object instance.
Value is either 0 or

equals

Added in API level 34
fun equals(other: Any?): Boolean

Indicates whether some other object is "equal to" this one.

The equals method implements an equivalence relation on non-null object references:

  • It is reflexive: for any non-null reference value x, x.equals(x) should return true.
  • It is symmetric: for any non-null reference values x and y, x.equals(y) should return true if and only if y.equals(x) returns true.
  • It is transitive: for any non-null reference values x, y, and z, if x.equals(y) returns true and y.equals(z) returns true, then x.equals(z) should return true.
  • It is consistent: for any non-null reference values x and y, multiple invocations of x.equals(y) consistently return true or consistently return false, provided no information used in equals comparisons on the objects is modified.
  • For any non-null reference value x, x.equals(null) should return false.

An equivalence relation partitions the elements it operates on into equivalence classes; all the members of an equivalence class are equal to each other. Members of an equivalence class are substitutable for each other, at least for some purposes.

Parameters
obj the reference object with which to compare.
o This value may be null.
Return
Boolean true if this object is the same as the obj argument; false otherwise.

hashCode

Added in API level 34
fun hashCode(): Int

Returns a hash code value for the object. This method is supported for the benefit of hash tables such as those provided by java.util.HashMap.

The general contract of hashCode is:

  • Whenever it is invoked on the same object more than once during an execution of a Java application, the hashCode method must consistently return the same integer, provided no information used in equals comparisons on the object is modified. This integer need not remain consistent from one execution of an application to another execution of the same application.
  • If two objects are equal according to the equals method, then calling the hashCode method on each of the two objects must produce the same integer result.
  • It is not required that if two objects are unequal according to the equals method, then calling the hashCode method on each of the two objects must produce distinct integer results. However, the programmer should be aware that producing distinct integer results for unequal objects may improve the performance of hash tables.
Return
Int a hash code value for this object.
