Just try out this code for video freeze problem:
#Override
public void play() {
player.setPlayWhenReady(true);
player.getPlaybackState();
}
#Override
public void pause() {
player.setPlayWhenReady(false);
player.getPlaybackState();
}
Here player.getPlaybackState(); is help full to get it to back state.

I think there must be something going on in the oncreate function.
Here is my MainFragment.java code. Note that it's primarily from the Facebook Login and Sharing tutorial on their website.
public class MainFragment extends Fragment {
private Button shareButton;
private static final List<String> PERMISSIONS = Arrays.asList("publish_actions");
private static final String PENDING_PUBLISH_KEY = "pendingPublishReauthorization";
private boolean pendingPublishReauthorization = false;
private static final String TAG = MainFragment.class.getSimpleName();
private TextView coordinates;
private UiLifecycleHelper uiHelper;
private final List<String> permissions;
public MainFragment() {
permissions = Arrays.asList("user_status");
}
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
uiHelper = new UiLifecycleHelper(getActivity(), callback);
uiHelper.onCreate(savedInstanceState);
}
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View view = inflater.inflate(R.layout.activity_main, container, false);
shareButton = (Button) view.findViewById(R.id.shareButton);
coordinates = (TextView) view.findViewById(R.id.coordinates);
shareButton.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
publishStory();
}
});
LoginButton authButton = (LoginButton) view.findViewById(R.id.authButton);
authButton.setFragment(this);
authButton.setReadPermissions(permissions);
if (savedInstanceState != null) {
pendingPublishReauthorization =
savedInstanceState.getBoolean(PENDING_PUBLISH_KEY, false);
}
return view;
}
#Override
public void onResume() {
super.onResume();
// For scenarios where the main activity is launched and user
// session is not null, the session state change notification
// may not be triggered. Trigger it if it's open/closed.
Session session = Session.getActiveSession();
if (session != null &&
(session.isOpened() || session.isClosed()) ) {
onSessionStateChange(session, session.getState(), null);
}
uiHelper.onResume();
}
#Override

}
} else if (state.isClosed()) {

}
}
private Session.StatusCallback callback = new Session.StatusCallback() {

if (!isSubsetOf(PERMISSIONS, permissions)) {
pendingPublishReauthorization = true;
Session.NewPermissionsRequest newPermissionsRequest = new Session
.NewPermissionsRequest(this, PERMISSIONS);
session.requestNewPublishPermissions(newPermissionsRequest);
return;
}
String text = coordinates.getText().toString();
Bundle postParams = new Bundle();
postParams.putString("name", "My Location!");
postParams.putString("caption", "Thanks to Hot and Cold");
postParams.putString("description", text);

.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();
}
}
private boolean isSubsetOf(Collection<String> subset, Collection<String> superset) {
for (String string : subset) {
if (!superset.contains(string)) {
return false;
}
}
return true;
}
}

So apparently I was spot on about the Fragment causing the issue. to Resolve it, I just added Context to the fragment class, i imported all of the Location logic into MainFragment, and now it works!

Android - Facebook SDK login -> logout -> login not working

I have an Android application (very simple one, just starting to learn the basics). I've implemented Facebook login, which is almost working perfectly. Starting the app first time everything works just fine: pressing the login button, asking for permissions, logging in, then the app shows the authenticated page for the user. When pressing the logout button it shows me the login page again, so that works too. Now when I try to log in again it doesn't work. It opens the facebook stuff again for some seconds then it just goes back to the login page like nothing have happened. If I remove the permissions on facebook for the app and try log in again it works again. So for some reason I can't log in when I already have the permission I guess...
Here is the code:
package com.just.simply.myapplication;
import android.content.Intent;
import android.os.Bundle;
import android.support.v4.app.Fragment;
import android.support.v4.app.FragmentActivity;
import android.support.v4.app.FragmentManager;

private Fragment[] fragments = new Fragment[FRAGMENT_COUNT];
private boolean isResumed = false;
private MenuItem settings;
#Override

super.onCreate(savedInstanceState);
uiHelper = new UiLifecycleHelper(this, callback);
uiHelper.onCreate(savedInstanceState);
setContentView(R.layout.activity_my);
FragmentManager fm = getSupportFragmentManager();
fragments[SPLASH] = fm.findFragmentById(R.id.splashFragment);
fragments[SELECTION] = fm.findFragmentById(R.id.selectionFragment);
fragments[SETTINGS] = fm.findFragmentById(R.id.userSettingsFragment);
FragmentTransaction transaction = fm.beginTransaction();
for(int i = 0; i < fragments.length; i++) {
transaction.hide(fragments[i]);
}
transaction.commit();
}
#Override

// Get the number of entries in the back stack

// Clear the back stack
for (int i = 0; i < backStackSize; i++) {

}

} else if (state.isClosed()) {
// If the session state is closed:

showFragment(SPLASH, false);
}
}
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
if (item.equals(settings)) {
showFragment(SETTINGS, true);
return true;
}
return false;
}
#Override
protected void onResumeFragments() {
super.onResumeFragments();
Session session = Session.getActiveSession();
if (session != null && session.isOpened()) {
// if the session is already open,
// try to show the selection fragment
showFragment(SELECTION, false);
} else {
// otherwise present the splash screen
// and ask the person to login.
showFragment(SPLASH, false);
}
}
#Override
public boolean onPrepareOptionsMenu(Menu menu) {
// only add the menu when the selection fragment is showing
if (fragments[SELECTION].isVisible()) {
if (menu.size() == 0) {
settings = menu.add(R.string.settings);
}
return true;
} else {
menu.clear();
settings = null;
}
return false;
}
private UiLifecycleHelper uiHelper;
private Session.StatusCallback callback =
new Session.StatusCallback() {
#Override
public void call(Session session,
SessionState state, Exception exception) {
onSessionStateChange(session, state, exception);
}
};
private void showFragment(int fragmentIndex, boolean addToBackStack) {
FragmentManager fm = getSupportFragmentManager();
FragmentTransaction transaction = fm.beginTransaction();
for (int i = 0; i < fragments.length; i++) {
if (i == fragmentIndex) {
transaction.show(fragments[i]);
} else {
transaction.hide(fragments[i]);
}
}
if (addToBackStack) {
transaction.addToBackStack(null);
}
transaction.commit();
}
}
Any help would be appreciated! If any other files needed just ask.
Thanks!
