Public constructors

Exception

Added in API level 1

Exception()

Constructs a new exception with null as its detail message. The cause is not initialized, and may subsequently be initialized by a call to initCause.

Exception

Added in API level 1

Exception(message: String!)

Constructs a new exception with the specified detail message. The cause is not initialized, and may subsequently be initialized by a call to initCause.

Parameters
message	String!: the detail message. The detail message is saved for later retrieval by the getMessage() method.

Exception

Added in API level 1

Exception(
    message: String!, 
    cause: Throwable!)

Constructs a new exception with the specified detail message and cause.

Note that the detail message associated with cause is not automatically incorporated in this exception's detail message.

Parameters
message	String!: the detail message (which is saved for later retrieval by the getMessage() method).
cause	Throwable!: the cause (which is saved for later retrieval by the getCause() method). (A null value is permitted, and indicates that the cause is nonexistent or unknown.)

Exception

Added in API level 1

Exception(cause: Throwable!)

Constructs a new exception with the specified cause and a detail message of (cause==null ? null : cause.toString()) (which typically contains the class and detail message of cause). This constructor is useful for exceptions that are little more than wrappers for other throwables (for example, ).

Parameters
cause	Throwable!: the cause (which is saved for later retrieval by the getCause() method). (A null value is permitted, and indicates that the cause is nonexistent or unknown.)

Protected constructors

Exception

Added in API level 24

protected Exception(
    message: String!, 
    cause: Throwable!, 
    enableSuppression: Boolean, 
    writableStackTrace: Boolean)

Constructs a new exception with the specified detail message, cause, suppression enabled or disabled, and writable stack trace enabled or disabled.

Parameters
message	String!: the detail message.
cause	Throwable!: the cause. (A null value is permitted, and indicates that the cause is nonexistent or unknown.)
enableSuppression	Boolean: whether or not suppression is enabled or disabled
writableStackTrace	Boolean: whether or not the stack trace should be writable
