仔细检查您使用的哈希键是否正确.请参阅此答案以设置您的哈希键

Key hash for Android-Facebook app

此外,使用Keytool对我的HashKey没有帮助,而是我遵循了本指南中的建议：

https://developers.facebook.com/docs/getting-started/facebook-sdk-for-android/3.0/

在步骤4中,请参阅疑难解答,并修改代码以输出您的HashKey并使用该代码.我从Keytool生成的hashkey与这个很不一样.之后重新编译一切,它应该工作正常.

我的Facebook布局按钮

<com.facebook.widget.LoginButton
    android:id="@+id/authButton"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_alignParentBottom="true"
    android:layout_centerHorizontal="true" 
    />

片段是

public class FacebookFragment extends Fragment {
private static final String TAG = "FacebookFragment";
private UiLifecycleHelper uiHelper;
private Session.StatusCallback callback = new Session.StatusCallback() {
    @Override
    public void call(final Session session,final SessionState state,final Exception exception) {
        onSessionStateChange(session,state,exception);
    }
};

@Override
public View onCreateView(LayoutInflater inflater,ViewGroup container,Bundle savedInstanceState) {
    View view = inflater.inflate(R.layout.activity_main,container,false);
    LoginButton authButton = (LoginButton) view.findViewById(R.id.authButton);
    authButton.setFragment(this);
    authButton.setReadPermissions(Arrays.asList("user_likes","user_status"));
    return view;
}

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    uiHelper = new UiLifecycleHelper(getActivity(),callback);
    uiHelper.onCreate(savedInstanceState);
}

@Override
public void onResume() {
    super.onResume();
    Session session = Session.getActiveSession();
    if (session != null &&
            (session.isOpened() || session.isClosed()) ) {
        onSessionStateChange(session,session.getState(),null);
    }

    uiHelper.onResume();
}

@Override
public void onActivityResult(int requestCode,int resultCode,Intent data) {
    super.onActivityResult(requestCode,resultCode,data);
    uiHelper.onActivityResult(requestCode,data);
}

@Override
public void onPause() {
    super.onPause();
    uiHelper.onPause();
}

@Override
public void onDestroy() {
    super.onDestroy();
    uiHelper.onDestroy();
}

@Override
public void onSaveInstanceState(Bundle outState) {
    super.onSaveInstanceState(outState);
    uiHelper.onSaveInstanceState(outState);
}

private void onSessionStateChange(Session session,SessionState state,Exception exception) {
    if (state.isOpened()) {
        Log.i(TAG,"Logged in...");
    } else if (state.isClosed()) {
        Log.i(TAG,"Logged out...");
    }
    else
        Log.i(TAG,session.toString());
}

}

在活动中,我已经实现了所需的onActivityResult并检索了片段

protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    if(savedInstanceState == null) {
            // Add the fragment on initial activity setup
            mainFragment = new FacebookFragment();
            getSupportFragmentManager()
            .beginTransaction()
            .add(android.R.id.content,mainFragment)
            .commit();
        } else {
            // Or set the fragment from restored state info
            mainFragment = (FacebookFragment) getSupportFragmentManager()
            .findFragmentById(android.R.id.content);
        }   
}


    @Override
public void onActivityResult(int requestCode,data);
    Session.getActiveSession().onActivityResult(this,requestCode,data);
}

我想也许问题可能在于Key Hash,但我完全按照Key hash for Android-Facebook app问题上的答案完成了指示

我有一个图像文件对象试图使用Jumblr API发布到Tumblr

我的问题

当我尝试发布图像时,我得到com.tumblr.jumblr.exceptions.JumblrException：错误的请求响应代码：400

我的代码

client = new JumblrClient(CONSUMER_KEY,SECRET_KEY);
                            client.setToken(TOKEN,TOKEN_SECRET);
                            User user=client.user();
                            userName=user.getName();

                            PhotoPost photoPost=client.newPost(client.user().getBlogs().get(0).getName(),PhotoPost.class);
                            photoPost.setCaption("My Tumblr post");


                            photoPost.setPhoto(new Photo(Methods.FILE_IMAGE));
                            photoPost.save();

而不是这个方法(它以某种方式触发Android画廊？无法找到Methods.FILE_IMAGE的任何javadoc)

photoPost.setPhoto(new Photo(Methods.FILE_IMAGE));

我建议你试试任何味道

photoPost.setData(new File(fileName)); //if it''s possible on Android

请尝试使用不同的文件：Tumblr不仅有文件大小限制,还有一些奇怪的检查文件是否有效.我上传的~3％的gif文件丢弃请求响应代码：400.这些文件不超过GIF大小限制并且它们在我的机器上显示正常,但是Tumblr由于某种原因拒绝它们,所以请尝试使用post.setData并使用一些防弹有效文件进行尝试,因为其余的代码 – 看起来你肯定做得对
