AndroidJNIHelper.GetFieldID
static function GetFieldID(javaClass: IntPtr, fieldName: string, signature: string = "", isStatic: bool = false): IntPtr;
static IntPtr GetFieldID(IntPtr javaClass, string fieldName, string signature = "", bool isStatic = false);
static def GetFieldID(javaClass as IntPtr, fieldName as string, signature as string = "", isStatic as bool = false) as IntPtr
Parameters

javaClass Raw JNI Java class object (obtained by calling AndroidJNI.FindClass).
fieldName Name of the field as declared in Java.
signature Field signature (e.g. obtained by calling AndroidJNIHelper.GetSignature).
isStatic Set to true for static fields; false for instance (nonstatic) fields.
Description

Scans a particular Java class for a field 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 field with the correct name will be returned.

static function GetFieldID(jclass: IntPtr, fieldName: string, isStatic: bool): IntPtr;
static IntPtr GetFieldID(IntPtr jclass, string fieldName, bool isStatic);
static def GetFieldID(jclass as IntPtr, fieldName as string, isStatic as bool) as IntPtr
Parameters

javaClass Raw JNI Java class object (obtained by calling AndroidJNI.FindClass).
fieldName Name of the field as declared in Java.
isStatic Set to true for static fields; false for instance (nonstatic) fields.
Description

Get a JNI field ID based on type detection. Generic parameter represents the field type.

Scans a particular Java class for a field matching a signature of the field type. The signature comparison is done to allow for sub-/base-classes of the class types.
