我想在 Facebook 上分享手机 SD 卡上的图像。
我的问题是运行应用程序后，我可以看到以下消息
Myapplication 想要访问您的公开个人资料和好友列表。
但是当我按 OK 并转到我的 Facebook 页面时，我在那里看不到任何图像。
我正在按照此链接上的说明进行操作，我的代码如下
public class PhotoActivity extends BaseFragmentActivity {
private static final String MIME_TYPE = "image/jpeg";
private Uri uri;
private ImageView mPhotoView;
private Session.StatusCallback mStatusCallback = new SessionStatusCallback();
private boolean mPostToWall = false;
private ImageButton retakeBtn;
private class SessionStatusCallback implements Session.StatusCallback {
@Override
public void call(Session session, SessionState state,
Exception exception) {
if (session.isOpened() && mPostToWall) {
share();
}
}
}
@Override
public void onStart() {
super.onStart();
Session.getActiveSession().addCallback(mStatusCallback);
}
@Override

super.onStop();
Session.getActiveSession().removeCallback(mStatusCallback);
}
@Override

super.onActivityResult(requestCode, resultCode, data);
Session.getActiveSession().onActivityResult(this, requestCode,
resultCode, data);
}

mPhotoView.setDrawingCacheEnabled(true);
mPhotoView.buildDrawingCache();
Bitmap bmap = mPhotoView.getDrawingCache();
ByteArrayOutputStream stream = new ByteArrayOutputStream();
bmap.compress(Bitmap.CompressFormat.JPEG, 80, stream);

bundle.putByteArray("picture", byteArray);
