com.facebook.FacebookException:尝试使用未打开的Session
我整合了facebook分享,它在过去几天工作得很好,但是今天在问这个问题之前的2个小时我正面临着这个问题.
我正在使用此代码登录:
Session.openActiveSession(this, true, new Session.StatusCallback() {
// callback when session changes state
@Override
public void call(Session session, SessionState state, Exception exception) {
if (state.isOpened()) {
// make request to the /me API
Request.newMeRequest(session, new Request.GraphUserCallback() {
// callback after Graph API response with user object
@Override
public void onCompleted(GraphUser user, Response response) {
if (user != null) {
Toast.makeText(ImagePagerActivity.this, user.getName()+" Logged In...", Toast.LENGTH_LONG).show();
}
}
}).executeAsync();
}
}
});
publishFeedDialog();
问题是if()条件总是假的,我也用过session.isOpened()它也返回false,我很困惑为什么会发生这种情况.
我已经在清单中声明了INTERNET,ACCESSNETWORKSTATE,权限
<application>
..........
..........
<meta-data android:name="com.facebook.sdk.ApplicationId" android:value="@string/app_id"/>
</application>
请帮忙...
编辑
这是我所实现的代码,你可以看到onCreateOptionsMenu,onOptionsItemSelected,onActivityResult,publishFeedDialog
@Override
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.action_bar_share_menu, menu);
MenuItem item = menu.findItem(R.id.menu_item_share1);
return true;
}
@Override
public boolean onOptionsItemSelected(MenuItem item) {
switch (item.getItemId()) {
case R.id.menu_item_share1: // facebook item selected
Toast.makeText(this, "Menu Item 1 selected", Toast.LENGTH_SHORT).show();
//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 (state.isOpened()) {
// make request to the /me API
Request.newMeRequest(session, new Request.GraphUserCallback() {
// callback after Graph API response with user object
@Override
public void onCompleted(GraphUser user, Response response) {
if (user != null) {
Toast.makeText(ImagePagerActivity.this, user.getName()+" Logged In...", Toast.LENGTH_LONG).show();
}
}
}).executeAsync();
}
}
});
publishFeedDialog();
}
return true;
}
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
uiHelper.onActivityResult(requestCode, resultCode, data, new FacebookDialog.Callback() {
@Override
public void onError(FacebookDialog.PendingCall pendingCall, Exception error, Bundle data) {
Log.e("Activity", String.format("Error: %s", error.toString()));
}
@Override
public void onComplete(FacebookDialog.PendingCall pendingCall, Bundle data) {
Log.i("Activity", "Success!");
}
});
}
@Override
protected void onResume() {
super.onResume();
uiHelper.onResume();
}
@Override
protected void onSaveInstanceState(Bundle outState) {
outState.putInt(STATE_POSITION, pager.getCurrentItem());
super.onSaveInstanceState(outState);
uiHelper.onSaveInstanceState(outState);
}
@Override
public void onPause() {
super.onPause();
uiHelper.onPause();
}
@Override
public void onDestroy() {
super.onDestroy();
uiHelper.onDestroy();
}
private void publishFeedDialog() {
Log.v("pos",""+pos);
Bundle params = new Bundle();
params.putString("name", ItemListApplication.names.get(pos).getItem());
params.putString("caption", "Irrational beliefs");
params.putString("description",ItemListApplication.names.get(pos).getDesc() );
params.putString("link", "https://www.facebook.com/vivek.warde.3?ref=tn_tnmn");
if(pos==0) params.putString("picture","http://i.imgur.com/lOIUcW2.jpg");
else params.putString("picture",imageUrls[pos]);
WebDialog feedDialog = (
new WebDialog.FeedDialogBuilder(this,
Session.getActiveSession(),
params))
.setOnCompleteListener(new OnCompleteListener() {
@Override
public void onComplete(Bundle values,
FacebookException error) {
if (error == null) {
// When the story is posted, echo the success
// and the post Id.
final String postId = values.getString("post_id");
if (postId != null) {
Toast.makeText(ImagePagerActivity.this,
"Posted story, id: "+postId,
Toast.LENGTH_SHORT).show();
} else {
// User clicked the Cancel button
Toast.makeText(ImagePagerActivity.this,
"Publish cancelled",
Toast.LENGTH_SHORT).show();
}
} else if (error instanceof FacebookOperationCanceledException) {
// User clicked the "x" button
Toast.makeText(ImagePagerActivity.this,
"Publish cancelled",
Toast.LENGTH_SHORT).show();
} else {
// Generic, ex: network error
Toast.makeText(ImagePagerActivity.this,
"Error posting story",
Toast.LENGTH_SHORT).show();
}
}
})
.build();
feedDialog.show();
}
处理这个问题可能有很多原因.你应该检查一下:
我正在使用此代码通过Facebook登录:
class MyFragment extends Fragment {
//... some code
SessionStatusCallback statusCallback = new SessionStatusCallback();
public void login() {
Session session = Session.getActiveSession();
if (!session.isOpened() && !session.isClosed()) {
session.openForRead(new Session.OpenRequest(this).setCallback(statusCallback));
} else {
Session.openActiveSession(getActivity(), this, true, statusCallback);
}
}
private class SessionStatusCallback implements Session.StatusCallback {
@Override
public void call(Session session, SessionState state, Exception exception) {
if (exception != null) {
handleException(exception);
}
if (state.isOpened()) {
afterLogin();
} else if (state.isClosed()) {
afterLogout();
}
}
}
}
如果未打开会话,则应将其打开以供阅读(或者如果需要,可以发布).
检查meta-dataAndroidManifest文件中的标签,是否有正确的应用程序ID？
经常发生错误不在Android应用程序内,但在Facebook应用程序设置.在facebook应用程序的设置页面中应该是正确的软件包名称,您应该为您的应用程序添加密钥哈希值(每种版本类型都不同,在大多数情况下是调试和发布).
要获取哈希键,您可以运行脚本
keytool -exportcert -alias YOUR_ALIAS -keystore PATH_TO_KEYSTORE_FILE | openssl sha1 -binary | openssl base64
或者你可以在代码中获取它:
PackageInfo info;
try {
info = getPackageManager().getPackageInfo("YOUR_APP_PACKAGE", PackageManager.GET_SIGNATURES);
for (Signature signature : info.signatures) {
MessageDigest md;
md = MessageDigest.getInstance("SHA");
md.update(signature.toByteArray());
String keyhash = new String(Base64.encode(md.digest(), 0));
//string something is what you should paste as key hash
Log.e("hash key", keyhash);
}
} catch (NameNotFoundException e1) {
Log.e("name not found", e1.toString());
} catch (NoSuchAlgorithmException e) {
Log.e("no such an algorithm", e.toString());
} catch (Exception e) {
Log.e("exception", e.toString());
}
在状态和评论选项卡内的Facebook应用程序的设置页面中,您应该公开应用程序.或者,如果您仍然不想将其公开,则应为可以使用您的Android应用程序的所有用户添加角色(在"角色"选项卡中).
此外,如果它没有帮助,尝试调试方法
public void call(Session session, SessionState state, Exception exception)
通常是正常的消息,为什么授权不成功
