在发布故事方法中，我添加一个日志以查看程序是否已通过代码行：
private void publishStory() {
Session session = Session.getActiveSession();
if (session != null){
Log.d("INFO","session is not NULL");
// Check for publish permissions
List<String> permissions = session.getPermissions();
if (!isSubsetOf(PERMISSIONS, permissions)) {
Log.d("INFO","setting permission");
pendingPublishReauthorization = true;
Session.NewPermissionsRequest newPermissionsRequest = new Session
.NewPermissionsRequest(this, PERMISSIONS);
session.requestNewPublishPermissions(newPermissionsRequest);
return;
}
Bundle postParams = new Bundle();
postParams.putString("name", "Facebook SDK for Android");
postParams.putString("caption", "Build great social apps and get more installs.");
postParams.putString("description", "The Facebook SDK for Android makes it easier and faster to develop Facebook integrated Android apps.");
postParams.putString("link", "https://developers.facebook.com/android");
postParams.putString("picture", "https://raw.github.com/fbsamples/ios-3.x-howtos/master/Images/iossdk_logo.png");
Log.d("INFO","finish construct message");
Request.Callback callback= new Request.Callback() {
public void onCompleted(Response response) {
Log.d("INFO","on request complete!");
JSONObject graphResponse = response
.getGraphObject()
.getInnerJSONObject();
String postId = null;
try {
postId = graphResponse.getString("id");
} catch (JSONException e) {
Log.i(TAG,
"JSON error "+ e.getMessage());
}
FacebookRequestError error = response.getError();
if (error != null) {
Toast.makeText(getActivity()
.getApplicationContext(),
error.getErrorMessage(),
Toast.LENGTH_SHORT).show();
} else {
Toast.makeText(getActivity()
.getApplicationContext(),
postId,
Toast.LENGTH_LONG).show();
}
}
};
Request request = new Request(session, "me/feed", postParams,
HttpMethod.POST, callback);
RequestAsyncTask task = new RequestAsyncTask(request);
task.execute();
}
}
问题是，当我执行上面的方法时，程序运行良好，直到它弹出一个验证发布权限窗口并且我允许它，屏幕再次继续到黑屏，其上有不确定的进度条，然后窗口只是自己解雇。
实际上，从logcat我可以得出结论它没有通过“on request complete”行。
为什么会这样？任何线索？
谢谢！

哦是的，我目前正在遵循此解决方案Updated - Android Facebook api 3.0 error: Cannot call LoginActivity with a null calling package
像你说的那样，我已经添加了像这样的onActivityResult@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
Session.getActiveSession().onActivityResult(this, requestCode, resultCode, data);
}
它有效！虽然我在对话类
上安排了这些行public void createFacebookConnection() {
Session session = new Session(MapScreen.this);
Session.setActiveSession(session);
Settings.addLoggingBehavior(LoggingBehavior.INCLUDE_ACCESS_TOKENS);
Session.StatusCallback statusCallback = new Session.StatusCallback() {
@Override
public void call(Session session, SessionState state, Exception exception) {
String message = "Facebook session status changed - " + session.getState() + " - Exception: " + exception;
Log.w("Facebook test", message);
if (session.isOpened() || session.getPermissions().contains("publish_actions")) {
publishToWall();
} else if (session.isOpened()) {
OpenRequest open = new OpenRequest(MapScreen.this).setCallback(this);
List<String> permission = new ArrayList<String>();
permission.add("publish_actions");
open.setPermissions(permission);
Log.w("Facebook test", "Open for publish");
session.openForPublish(open);
}
}
};
if (!session.isOpened() && !session.isClosed() && session.getState() != SessionState.OPENING) {
session.openForRead(new Session.OpenRequest(MapScreen.this).setCallback(statusCallback));
} else {
Log.w("Facebook test", "Open active session");
Session.openActiveSession(MapScreen.this, true, statusCallback);
}
}
void publishToWall() {
Session session = Session.getActiveSession();
Bundle postParams = new Bundle();
postParams.putString("name", "Merauke Android");
postParams.putString("caption", hotelName);
postParams.putString("description", hotelName+" is a luxury hotel which is located in the city of Bandung.");
postParams.putString("link", "https://developers.facebook.com/android");
postParams.putString("picture", "http://www.jejaringhotel.com/android/hotelimages/hotel-3.jpg");
Log.i("DIALOG","feed set");
Request.Callback callback = new Request.Callback() {
public void onCompleted(Response response) {
FacebookRequestError error = response.getError();
if (error != null) {
Toast.makeText(MapScreen.this, error.getErrorMessage(), Toast.LENGTH_SHORT).show();
} else {

String postId = null;
try {
postId = graphResponse.getString("id");
} catch (JSONException e) {
Log.i("Facebook error", "JSON error " + e.getMessage());
}
//TODO Toast.makeText(context, postId, Toast.LENGTH_LONG).show();
Toast.makeText(MapScreen.this, "Posted on wall success!", Toast.LENGTH_SHORT).show();
}
}
};
Request request = new Request(Session.getActiveSession(), "me/feed", postParams, HttpMethod.POST, callback);
RequestAsyncTask task = new RequestAsyncTask(request);
task.execute();
}
