Name	Description
CallNonvirtualBooleanMethod(IntPtr, IntPtr, IntPtr)	Invokes a parameterless Java instance method using the implementation selected by the specified class.
CallNonvirtualBooleanMethod(IntPtr, IntPtr, IntPtr, JValue*)	Calls a Java instance method that returns a Java `boolean`, selecting its implementation from the specified class.
CallNonvirtualBooleanMethod(IntPtr, IntPtr, IntPtr, JValue[])	Calls a Java instance method that returns a Java `boolean`, selecting its implementation from the specified class.

CallNonvirtualBooleanMethod(IntPtr, IntPtr, IntPtr)

Invokes a parameterless Java instance method using the implementation selected by the specified class.

public static bool CallNonvirtualBooleanMethod(IntPtr jobject, IntPtr jclass, IntPtr jmethod);

static member CallNonvirtualBooleanMethod : nativeint * nativeint * nativeint -> bool

Parameters

jobject: IntPtr
nativeint

A valid, non-null JNI reference to the Java object on which the method runs.

jclass: IntPtr
nativeint

A valid, non-null JNI reference to the class used to obtain jmethod. The class must be the object's class or one of its supertypes.

jmethod: IntPtr
nativeint

The identifier of a parameterless instance method obtained from jclass. The method must return a Java boolean.

Returns

Boolean

The Boolean value returned by the invoked Java method.

Applies to

CallNonvirtualBooleanMethod(IntPtr, IntPtr, IntPtr, JValue*)

Calls a Java instance method that returns a Java boolean, selecting its implementation from the specified class.

public static bool CallNonvirtualBooleanMethod(IntPtr jobject, IntPtr jclass, IntPtr jmethod, Android.Runtime.JValue* parms);

static member CallNonvirtualBooleanMethod : nativeint * nativeint * nativeint * nativeptr<Android.Runtime.JValue> -> bool

Parameters

jobject: IntPtr
nativeint

A live, non-null JNI object reference from the current VM, usable on the calling thread until the call returns or throws.

jclass: IntPtr
nativeint

A live, non-null JNI class reference for the object's class or one of its supertypes, usable on the calling thread until the call returns or throws.

jmethod: IntPtr
nativeint

A live instance method ID obtained for jclass. Its JNI signature must match the arguments and return a Java boolean. Keep its declaring class live.

parms: JValue*

A pointer to the arguments in JNI order and types. The storage must be readable for the argument count. Do not change the storage during the call, and keep referenced objects live.

Returns

Boolean

The value returned by the Java method.

Applies to

CallNonvirtualBooleanMethod(IntPtr, IntPtr, IntPtr, JValue[])

Calls a Java instance method that returns a Java boolean, selecting its implementation from the specified class.

public static bool CallNonvirtualBooleanMethod(IntPtr jobject, IntPtr jclass, IntPtr jmethod, params Android.Runtime.JValue[] parms);

static member CallNonvirtualBooleanMethod : nativeint * nativeint * nativeint * Android.Runtime.JValue[] -> bool

Parameters

jobject: IntPtr
nativeint

A live, non-null JNI object reference from the current VM, usable on the calling thread until the call returns or throws.

jclass: IntPtr
nativeint

A live, non-null JNI class reference for the object's class or one of its supertypes, usable on the calling thread until the call returns or throws.

jmethod: IntPtr
nativeint

A live instance method ID obtained for jclass. Its JNI signature must match the arguments and return a Java boolean. Keep its declaring class live.

parms: JValue[]

All arguments in JNI order and types. Do not change the array during the call, and keep referenced objects live.

Returns

Boolean

The value returned by the Java method.
