Java Android FacebookSDK 4.6.0共享位图问题

我正在尝试使用Facebook上的共享我的Android项目的位图，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。这是我的密码：

    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);



        }
    });

您必须注册回调以查看实际发生的情况

    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
 });
        }

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