Android FacebookSDK 4.6.0共享位图问题

Question

我正试图从我的Android项目中分享一个位图，使用这个例子来自Facebook，但是

当我在我的项目中实现示例时-没有任何事情发生，没有警告，没有错误。下面是我的代码:

    shareButton.setOnClickListener(new OnClickListener() {
        @Override
        public void onClick(View v) {
            Bitmap image = BitmapFactory.decodeResource(getResources(), R.drawable.ic_launcher);
            SharePhoto photo = new SharePhoto.Builder()
                    .setBitmap(image)
                    .build();
            SharePhotoContent content = new SharePhotoContent.Builder()
                    .addPhoto(photo)
                    .build();

            ShareDialog shareDialog = new ShareDialog(MainActivity.this);
            shareDialog.show(content);

        }
    });

您必须注册一个回调来查看实际发生了什么。

    public class MainActivity extends FragmentActivity {
        CallbackManager callbackManager;
        ShareDialog shareDialog;
        @Override
        public void onCreate(Bundle savedInstanceState) {
            super.onCreate(savedInstanceState);
            FacebookSdk.sdkInitialize(getApplicationContext());
            callbackManager = CallbackManager.Factory.create();
            shareDialog = new ShareDialog(this);
            shareDialog.registerCallback(callbackManager, new FacebookCallback<Sharer.Result>() { 
    // onSuccess method
    // onError method
    // onCancel method
 });
        }

然后在onActivityResult中调用SDK的callbackManager来处理响应:

@Override
protected void onActivityResult(final int requestCode, final int resultCode, final Intent data) {
    super.onActivityResult(requestCode, resultCode, data);
    callbackManager.onActivityResult(requestCode, resultCode, data);
}
