Android Facebook api 3.0 error: Cannot call LoginActivity with a null calling package
I managed to find my problem. Although I wasn't setting
android:launchMode="singleTask"
my LoginActivity had
android:noHistory="true"
which results in that exception. I put noHistory true because I didn't want the user to be able to press back button on the first activity after login and go back to login screen. Now I need to find another solution.
After lots of searching I figured out that there don't seems to be a way to startActivityForResult with LocalActivityManager used in the tabs.
So I ended up accepting that it will need an activity filling the entire screen. The activity is only shown a second or so with good network connection - I have made it with a republish option on errors also..
Start publish activity:
Intent intent = new Intent(this, FacebookShareActivity.class);
intent.putExtra(Constants.FACEBOOK_MESSAGE, shareMessage.getMessage());
startActivityForResult(intent, 1);
Facebook share activity code - publishing to users wall:
public class FacebookShareActivity extends Activity {
String message;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.facebook_publishing);
message = getIntent().getExtras().getString(Constants.FACEBOOK_MESSAGE);
createFacebookConnection();
}
public void republishButton_Click(View view){
setVisibilityForRepublishButton(false);
createFacebookConnection();
}
public void createFacebookConnection() {
Session session = new Session(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;
//Toast.makeText(FacebookShareActivity.this, message, Toast.LENGTH_SHORT).show();
Log.w("Facebook test", message);
if (session.isOpened() || session.getPermissions().contains("publish_actions")) {
publishToWall();
} else if (session.isOpened()) {
OpenRequest open = new OpenRequest(FacebookShareActivity.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(this).setCallback(statusCallback));
} else {
Log.w("Facebook test", "Open active session");
Session.openActiveSession(this, true, statusCallback);
}
}
private void setVisibilityForRepublishButton(Boolean visible) {
((Button) findViewById(R.id.republishButton)).setVisibility(visible ? View.VISIBLE : View.GONE);
}
@Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
Session.getActiveSession().onActivityResult(this, requestCode, resultCode, data);
//Toast.makeText(FacebookShareActivity.this, "onActivityResult", Toast.LENGTH_SHORT).show();
}
void publishToWall() {
Session session = Session.getActiveSession();
Bundle postParams = new Bundle();
postParams.putString("message", message);
final Context context = this;
Request.Callback callback = new Request.Callback() {
public void onCompleted(Response response) {
FacebookRequestError error = response.getError();
if (error != null) {
setVisibilityForRepublishButton(true);
Toast.makeText(context, error.getErrorMessage(), Toast.LENGTH_SHORT).show();
} else {
JSONObject graphResponse = response.getGraphObject().getInnerJSONObject();
String postId = null;
try {
postId = graphResponse.getString("id");
} catch (JSONException e) {
setVisibilityForRepublishButton(true);
Log.i("Facebook error", "JSON error " + e.getMessage());
}
//Toast.makeText(context, postId, Toast.LENGTH_LONG).show();
finish();
}
}
};
Request request = new Request(Session.getActiveSession(), "me/feed", postParams, HttpMethod.POST, callback);
RequestAsyncTask task = new RequestAsyncTask(request);
task.execute();
}
}
I've got the same problem : trying to log into facebook, with the dialog provided inside the SDK, but from an activity that was itself inside a tabgroup ; like ShareActivity above.
What I've done is basically called startActivityForResult on parent activity of ShareActivity (that is ShareGroupActivity), instead of calling it on ShareActivity.
So 1 , add this in ShareGroupActivity :
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
System.out.println("facebook status called");
super.onActivityResult(requestCode, resultCode, data);
Session.getActiveSession().onActivityResult(this, requestCode, resultCode, data);
}
2 you need to modify the class Session, inside FacebookSDK project, under src com.facebook
2.1 add a boolean member
public boolean insideTabGroup;
2.2 modify StartActivityDelegate, that is used by session to open login ; add the boolean as parameter
interface StartActivityDelegate {
public void startActivityForResult(Intent intent, int requestCode, boolean insideTabGroup);
public Activity getActivityContext();
}
2.3 inside the inner class AuthorizationRequest, modify the implementation of this delegate :
AuthorizationRequest(final Activity activity) {
startActivityDelegate = new StartActivityDelegate() {
@Override
public void startActivityForResult(Intent intent, int requestCode, boolean insideTabGroup) {
if(insideTabGroup) {
ActivityGroup parentActivity = (ActivityGroup) activity.getParent();
parentActivity.startActivityForResult(intent,requestCode);
} else {
activity.startActivityForResult(intent, requestCode);
}
}
@Override
public Activity getActivityContext() {
return activity;
}
};
}
2.4 Also, modify the other constructors of AuthorizationRequest, by just adding the boolean parameter. As I do not use login to facebook from somewhere else than an activity, that's ok.
2.5 Modifiy the tryLoginActivity method of Session class, to use the boolean member as a parameter :
private boolean tryLoginActivity(AuthorizationRequest request) {
Intent intent = getLoginActivityIntent(request);
if (!resolveIntent(intent)) {
return false;
}
try {
request.getStartActivityDelegate().startActivityForResult(intent, request.getRequestCode(),this.insideTabGroup);
} catch (ActivityNotFoundException e) {
return false;
}
return true;
}
3 Set the boolean member in the session :
Session session = Session.getActiveSession();
session.insideTabGroup = true;
That should do the trick.
