我正在尝试使用sdk for android将图片上传到Facebook。当我运行代码我的应用程序崩溃。有人能帮我吗。我不太确定如何使用sdk。还有其他方式上传图片吗？
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.fragment_main);
bm = BitmapFactory.decodeResource(getResources(), R.drawable.ic_launcher);
// start Facebook Login
Session.openActiveSession(this, true, new Session.StatusCallback() {
// callback when session changes state
@Override
public void call(Session session, SessionState state, Exception exception) {
if (session.isOpened()) {
// make request to the /me API
Request.newUploadPhotoRequest(session, bm, new Request.Callback() {
@Override
public void onCompleted(Response response)
{
// TODO Auto-generated method stub
if (isFinishing()) {
return;
}
if (response.getError() != null) { // [IF Failed Posting]
Log.d("", "photo upload problem. Error="+response.getError() );
} // [ENDIF Failed Posting]
Object graphResponse = response.getGraphObject().getProperty("id");
if (graphResponse == null || !(graphResponse instanceof String) ||
TextUtils.isEmpty((String) graphResponse)) { // [IF Failed upload/no results]
Log.d("", "failed photo upload/no response");
} else { // [ELSEIF successful upload]
fbPhotoAddress = "https://www.facebook.com/photo.php?fbid=" +graphResponse;
}
}
} ).executeAsync();
}
}
});
}
}
