do not use. | ## Exceptions |---------------------------------------------------------------------------------------------------------------------------------------------|--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------| | [GenericSignatureFormatError](https://developer.android.com/reference/kotlin/java/lang/reflect/GenericSignatureFormatError) | Thrown when a syntactically malformed signature attribute is encountered by a reflective method that needs to interpret the generic signature information for a type, method or constructor. | | [InvocationTargetException](https://developer.android.com/reference/kotlin/java/lang/reflect/InvocationTargetException) | InvocationTargetException is a checked exception that wraps an exception thrown by an invoked method or constructor. | | [MalformedParameterizedTypeException](https://developer.android.com/reference/kotlin/java/lang/reflect/MalformedParameterizedTypeException) | Thrown when a semantically malformed parameterized type is encountered by a reflective method that needs to instantiate it. | | [MalformedParametersException](https://developer.android.com/reference/kotlin/java/lang/reflect/MalformedParametersException) | Thrown when[the](https://developer.android.com/reference/kotlin/java/lang/reflect/Executable#getParameters())attempts to read method parameters from a class file and determines that one or more parameters are malformed. | | [UndeclaredThrowableException](https://developer.android.com/reference/kotlin/java/lang/reflect/UndeclaredThrowableException) | Thrown by a method invocation on a proxy instance if its invocation handler's[invoke](https://developer.android.com/reference/kotlin/java/lang/reflect/InvocationHandler#invoke(kotlin.Any,%20java.lang.reflect.Method,%20kotlin.Array))method throws a checked exception (a`Throwable`that is not assignable to`RuntimeException`or`Error`) that is not assignable to any of the exception types declared in the`throws`clause of the method that was invoked on the proxy instance and dispatched to the invocation handler. |
