Declaration

public static IntPtr GetMethodID(IntPtr javaClass, string methodName);

Declaration

public static IntPtr GetMethodID(IntPtr javaClass, string methodName, string signature);

Declaration

public static IntPtr GetMethodID(IntPtr javaClass, string methodName, string signature, bool isStatic = false);

Parameters

javaClass Raw JNI Java class object (obtained by calling AndroidJNI.FindClass).
methodName Name of the method as declared in Java.
signature Method signature (e.g. obtained by calling AndroidJNIHelper.GetSignature).
isStatic Set to true for static methods; false for instance (nonstatic) methods.

Description

Scans a particular Java class for a method matching a name and a signature.

The signature comparison is done to allow sub-/base-classes of a class types. If no signature is provided the first method with the correct name will be returned.

Declaration

public static IntPtr GetMethodID(IntPtr jclass, string methodName, object[] args, bool isStatic);

Parameters

javaClass Raw JNI Java class object (obtained by calling AndroidJNI.FindClass).
methodName Name of the method as declared in Java.
args Array with parameters to be passed to the method when invoked.
isStatic Set to true for static methods; false for instance (nonstatic) methods.

Description

Get a JNI method ID based on calling arguments.

Generic parameter represents the method return type, and the regular method assumes 'void' return type. Scans a particular Java class for a method matching a signature based on passed arguments. The signature comparison is done to allow for sub-/base-classes of the class types.
