我正在开发一个应用程序，用于检索当前用户的Facebook好友。我的代码正在我的设备上运行但是当我在任何其他设备上运行时，它没有显示任何结果。
你可以告诉我出错的地方吗？我的代码如下：
public class FaceBook extends Activity implements SearchView.OnQueryTextListener, SearchView.OnCloseListener{
ArrayList<Param> facebook_names = new ArrayList<Param>();
Param name = null;
Names_Adapter adapter;
ListView Names_List;
SearchView searchView;
int check_search =1;
ArrayList<Param>new_names;
private UiLifecycleHelper uiHelper;
private static final int REAUTH_ACTIVITY_CODE = 100;
@SuppressLint("NewApi")
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);

ActionBar bar = getActionBar();
bar.setDisplayOptions(ActionBar.DISPLAY_SHOW_CUSTOM);
bar.setCustomView(R.layout.custom_titlebar);
bar.setBackgroundDrawable(getResources().getDrawable(R.drawable.header));
//bar.setTitle("Main Menu");
bar.setDisplayShowHomeEnabled(true);
bar.setHomeButtonEnabled(true);
uiHelper = new UiLifecycleHelper(this, callback);
uiHelper.onCreate(savedInstanceState);
TextView myTitleText = (TextView) findViewById(R.id.mytext);
if ( myTitleText != null ) {
myTitleText.setText("Facebook");
}
Log.d("COMP", "TEST");
Names_List = (ListView) findViewById(R.id.listView1);
ImageButton reload = (ImageButton) findViewById(R.id.reload);
reload.setOnClickListener(new View.OnClickListener() {

startActivity(restart);
finish();
}
});
}

adapter.notifyDataSetChanged();
}
}
Names_Adapter adapter = new Names_Adapter(FaceBook.this,R.layout.facebook_names_list,new_names);
Names_List.setAdapter(adapter);
adapter.notifyDataSetChanged();
}
else
{

Names_List.setAdapter(adapter);
}
return false;
}
@Override

@Override

switch (itemId) {

private void makeRequest(Session session)
{
String fqlQuery = "SELECT uid,name,pic,profile_url FROM user WHERE uid IN " +

}
}catch(JSONException e){

}
}
});
Request.executeBatchAsync(request);
}
private void onSessionStateChange(final Session session, SessionState state, Exception exception) {
if (session != null && session.isOpened()) {
// Get the user's data.
makeRequest(session);
}
}
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 onSaveInstanceState(Bundle bundle) {
super.onSaveInstanceState(bundle);
uiHelper.onSaveInstanceState(bundle);
}
@Override
public void onPause() {
super.onPause();
uiHelper.onPause();
}
@Override
public void onDestroy() {
super.onDestroy();
uiHelper.onDestroy();
}
}
我还尝试使用restFB来访问Facebook好友。
AccessToken accessToken = new DefaultFacebookClient().obtainAppAccessToken(appid,app secret;
FacebookClient facebookClient = new DefaultFacebookClient(accessToken.getAccessToken());
User user = facebookClient.fetchObject("me", User.class);
当我这样做时，它给出了一个错误，指出必须使用有效的访问令牌来检索用户值。

转到Facebook开发人员网站，在您的应用的“状态和评论”下，将其设为 PUBLIC 。在“临时”测试完成后，您可以随时从公开中删除。
或
另一种方法是打印出您正在测试应用的每个设备的关键哈希值，然后将这些哈希值作为关键哈希值添加到您的应用的FB开发者的设置＆gt; Android中。< / p>
