我們正在嘗試使用android本機facebook sdk for facebook wall post。這樣Apportable：如何使用android本機facebook adk
.h文件中
#ifdef ANDROID
#import <BridgeKit/JavaObject.h>
#import <BridgeKit/AndroidActivity.h>
@interface BridgeKitExt : JavaObject
- (id)initWithString:(NSString*)str;
- (void)loginFacebook:(AndroidActivity*)activity;
@end
#endif
和.m文件這樣
#ifdef ANDROID
#import "BridgeKitExt.h"
#pragma clang diagnostic push
#pragma clang diagnostic ignored "-Wobjc-property-implementation"
#pragma clang diagnostic ignored "-Wincomplete-implementation"
@implementation BridgeKitExt
+ (void)initializeJava
{
[super initializeJava];
[BridgeKitExt registerConstructorWithSelector:@selector(initWithString:)
arguments:[NSString className], nil];
[BridgeKitExt registerInstanceMethod:@"loginFacebook"
selector:@selector(loginFacebook:)
arguments:@"android/app/Activity", nil];
}
+ (NSString *)className
{
return @"com.duksel.apportable.BridgeKitExt";
}
@end
#pragma clang diagnostic pop
#endif
BridgeKitExt.java文件
這裏我們使用的橋樑類是這樣

添加的Android FacebookSDK項目文件夾和文件configuration.json
"header_paths": ["./FacebookSDK/src"],
"sources": [ "java-wrappers/BridgeKitExt.m" ],
"java_sources": [ "java/src/com/duksel/apportable/BridgeKitExt.java" ],
"java_sourcepaths": [ "java/src" , "FacebookSDK/src" ],
但當構建，收到此錯誤
.../BridgeKitExt.java:128: class, interface, or enum expected
Session session = Session.getActiveSession();
^
/BridgeKitExt.java:129: class, interface, or enum expected
if (session != null && (session.isOpened() || session.isClosed())) {
^
