Sharing content on Facebook at onClick in RecyclerView

Sharing content on Facebook at onClick in RecyclerView - android

I am trying to share the app content on facebook in an onClick method inside RecyclerView. Recyclerview works fine and showing data properly before the onclick method.
All the dependencies and other stuff is being done in gradle file etc... The problem i am facing is as soon as the user clicks share button, new intent is generated, I am passing relevant parameters but activity doesn't perform any action.
Below is the code for opening Facebook(HomeActivity) onCreate() method:
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
FacebookSdk.sdkInitialize(getApplicationContext());
setContentView(R.layout.home);
if (savedInstanceState == null) {
Bundle extras = getIntent().getExtras();
if(extras == null) {
imageURL= null;
position=0;
} else {
imageURL= extras.getString("imageURL");
//position = extras.getInt("position");
}
} else {
imageURL= (String) savedInstanceState.getSerializable("imageURL");
//position= (int) savedInstanceState.getSerializable("position");
}
callbackManager = CallbackManager.Factory.create();
// loginDataBaseAdapter = new LoginDataBaseAdapter(this);
// loginDataBaseAdapter = loginDataBaseAdapter.open();
facebookLogin = (LoginButton) findViewById(R.id.login_button);
facebookLogin.registerCallback(callbackManager, callback);
}
And this is what I am doing during call back method, it login successfully but crashes afterwards.
public FacebookCallback<LoginResult> callback = new FacebookCallback<LoginResult>() {
#Override
public void onSuccess(LoginResult loginResult) {
// Toast.makeText(getApplicationContext(),"On facebook",Toast.LENGTH_LONG).show();
AccessToken accessToken = loginResult.getAccessToken();
ShareLinkContent content = new ShareLinkContent.Builder()
.setContentUrl(Uri.parse(imageURL))
.build();
ShareDialog.show(HomeActivity.this, content);
}
#Override
public void onCancel() {
}
#Override
public void onError(FacebookException error) {
Profile profile = Profile.getCurrentProfile();
textView.setText("Connection Lost ! Pleasr Try Again :" + profile.getName());
}
};
And this is how onClick() method is written:
#Override
public void onClick(View v) {
Intent intent = new Intent(context.getApplicationContext(),HomeActivity.class);
intent.putExtra("position",getAdapterPosition());
intent.putExtra("imageURL",uri);
context.startActivity(intent);
}
Can somebody guide me through this. I am not very experienced in making apps and sharing content on social apps. Any help would be highly appreciated.

You can directly share on facebook by using
try {
Intent intent1 = new Intent();
intent1.setClassName("com.facebook.katana", "com.facebook.katana.activity.composer.ImplicitShareIntentHandler");
intent1.setAction(Intent.ACTION_SEND);
intent1.setType("text/plain");
intent1.putExtra(Intent.EXTRA_TEXT, "any text");
startActivity(intent1);
} catch (Exception e) {
Intent intent = new Intent(Intent.ACTION_SEND);
String sharerUrl = "https://www.facebook.com/sharer/sharer.php?u=" + "any constant";
intent = new Intent(Intent.ACTION_VIEW, Uri.parse(sharerUrl));
intent.putExtra(Intent.EXTRA_TEXT, "any text");
startActivity(intent);
}
i.e. try to share on facebook app. if the app is not installed on device the share will be opened on browser

Intent activity after facebook login opened twice

I have a main activity that displays login option, if the user clicked login with FB button, I will call fblogin();, and if the login success then I will do intent to open home activity.
right now, the home activity seems to open twice. (i can see it appear twice, stacked)
private void Fblogin()
{
callbackmanager = CallbackManager.Factory.create();
// Set permissions
LoginManager.getInstance().logInWithReadPermissions(this, Arrays.asList("public_profile, email, user_birthday,user_friends"));
LoginManager.getInstance().registerCallback(callbackmanager, new FacebookCallback<LoginResult>() {
#Override
public void onSuccess(LoginResult loginResult) {
GraphRequest request = GraphRequest.newMeRequest(
loginResult.getAccessToken(),
new GraphRequest.GraphJSONObjectCallback() {
#Override
public void onCompleted(JSONObject object, GraphResponse response) {
Log.d("LoginActivity", response.toString());
Log.d("LoginActivity", object.toString());
String jsonresult = String.valueOf(object);
System.out.println("JSON Result" + jsonresult);
String str_firstname=null,str_id=null;
try {
str_firstname=object.getString("name");
str_id = object.getString("id");
String str_email = object.getString("email");
Intent home = new Intent(MainActivity.this , HomeActivity.class);
home.putExtra("name", str_firstname);
home.putExtra("URL", "https://graph.facebook.com/" + str_id + "/picture?width="+PROFILE_PIC_SIZE+"&height="+PROFILE_PIC_SIZE);
startActivity(home);
} catch (JSONException e) {
e.printStackTrace();
Log.d("xxxx","aa");
}
}
});
Bundle parameters = new Bundle();
parameters.putString("fields", "id,name,email,gender, birthday");
request.setParameters(parameters);
request.executeAsync();
}
#Override
public void onCancel() {
Log.v("LoginActivity", "cancel");
}
#Override
public void onError(FacebookException exception) {
Log.v("LoginActivity", exception.getCause().toString());
}
});
}
in my main activity, i call this in my on create FacebookSdk.sdkInitialize(getApplicationContext());
, iI also check for initial login status `
if ( AccessToken.getCurrentAccessToken() != null && Profile.getCurrentProfile()!=null ) {
Intent home = new Intent(MainActivity.this , HomeActivity.class);
startActivity(home);}
but I think that initial check has nothing to do with it becauseI tried to delete it too but it still happening.`
and in my Home Activity, I have not write any facebook related codes yet.

After eight hours trial with some debugging, i couldn't find any trace of what is causing my HomeActivity fires twice. for people who stuck in any similar case, if you want and if its not breaking out your code, you can try to make your activity appear only one instance by adding this on your activity declaration in the manifest:
android:launchMode = "singleTask"
this has been the solution for me right now cause i don't want to waste any time longer as i need to move on to the next progress. thank you for any assistance.

You are calling the activity twice. That is
when consider if you are logged in facebook and google then the both the code get executed.
in onCreate you are calling
if (opr.isDone())
{
// If the user's cached credentials are valid, the OptionalPendingResult will be "done"
// and the GoogleSignInResult will be available instantly.
Log.d("TAG", "Got cached sign-in");
GoogleSignInResult result = opr.get();
handleSignInResult(result); //check method for going to home activity
}
and
if ( AccessToken.getCurrentAccessToken() != null && Profile.getCurrentProfile()!=null ) {
//load profile and skip (loginfragment) to Home page
Intent home = new Intent(MainActivity.this , HomeActivity.class);
startActivity(home);
} else if ( IsLoggedManual ) { //IF already LOGGED IN MANUAL (SHAREDPREF)
Intent home = new Intent(MainActivity.this , HomeActivity.class);
startActivity(home);
}
Use these conditions as one eg
opr.isDone() || AccessToken.getCurrentAccessToken() != null && Profile.getCurrentProfile()!=null

Here you missed it, check out this code -
OptionalPendingResult<GoogleSignInResult> opr = Auth.GoogleSignInApi.silentSignIn(mGoogleApiClient);
if (opr.isDone()) {
// If the user's cached credentials are valid, the OptionalPendingResult will be "done"
// and the GoogleSignInResult will be available instantly.
Log.d("TAG", "Got cached sign-in");
GoogleSignInResult result = opr.get();
handleSignInResult(result);
}
Above cached sign-in will start HomeActivity as well as if your AccessToken is not null(you're logged in with facebook) - again will start Home Activity
//CHECK IF ALREADY LOGGED BY FB
if ( AccessToken.getCurrentAccessToken() != null && Profile.getCurrentProfile()!=null ) {
//load profile and skip (loginfragment) to Home page
Intent home = new Intent(MainActivity.this , HomeActivity.class);
startActivity(home);
}
Solution:
You should put these conditions using else if ladder statements...

How do I use SharedPreferences with Facebook SDK?

Currently this is how my FB login looks like:
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_login);
TAG = "Login.Activity";
//Callback manager manages callbacks into the FB SDK from an Activity's onActivityResult() Method.
callbackManager = CallbackManager.Factory.create();
loginButton = (LoginButton) findViewById(R.id.login_button);
loginButton.registerCallback(callbackManager, new FacebookCallback<LoginResult>() {
//If login in successful,
#Override
public void onSuccess(LoginResult loginResult) {
Profile profile = Profile.getCurrentProfile();
goMainScreen(profile);
}
#Override
public void onCancel() {
Toast.makeText(getApplicationContext(),R.string.cancel_login, Toast.LENGTH_LONG).show();
}
#Override
public void onError(FacebookException error) {
Toast.makeText(getApplicationContext(), R.string.error_login, Toast.LENGTH_LONG).show();
}
});
}
private void goMainScreen(Profile profile) {
if(profile != null){
//Passing in the name,id and photo from the profile.
Intent intent = new Intent(this, MainActivity.class);
// intent.putExtra("name",profile.getName());
intent.putExtra("id",profile.getId());
intent.putExtra("photo",profile.getProfilePictureUri(200,200));
intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP | Intent.FLAG_ACTIVITY_CLEAR_TASK | Intent.FLAG_ACTIVITY_NEW_TASK);
startActivity(intent);
}
}
#Override
//All Request Code, Result Code, and data are recieved by the activity
protected void onActivityResult(int requestCode, int resultCode, Intent data){
super.onActivityResult(requestCode,resultCode,data);
callbackManager.onActivityResult(requestCode,resultCode,data);
}
}
I would like to keep track of the user session throughout other activities and know if they have logged in before.Would I use sharedpreferences for this? If so will I be doing this at the beginning of the loginActivity?

Well you could use what provide the SDK and create a method like this one :
public boolean isLoggedIn() {
AccessToken accessToken = AccessToken.getCurrentAccessToken();
return accessToken != null;
}

ShareDialog doesn't open facebook app

Trying to implement facebook sharing, however it only works in webview if I set ShareDialog.Mode.AUTOMATIC, if I set it to NATIVE then nothing shows up at all and I don't receive no error callback. Facebook app is installed in the emulator.
Provider in manifest:
<provider android:authorities="com.facebook.app.FacebookContentProvider{myAppId}"
android:name="com.facebook.FacebookContentProvider"
android:exported="true"/>
Code for sharing:
public void share(String contentUrl,
Activity activity){
ShareLinkContent content = new ShareLinkContent.Builder()
.setContentUrl(Uri.parse(contentUrl))
.build();
ShareDialog dialog = new ShareDialog(activity);
dialog.registerCallback(callbackManager, new FacebookCallback<Sharer.Result>() {
#Override
public void onSuccess(Sharer.Result result) {
EventBus.getDefault().post(new ShareEvent(true));
}
#Override
public void onCancel() {
Log.e(TAG, "Facebook Share Cancel");
EventBus.getDefault().post(new ShareEvent(false));
}
#Override
public void onError(FacebookException error) {
Log.e(TAG, "Facebook share error: " + error.getMessage());
EventBus.getDefault().post(new ShareEvent(false));
}
})
dialog.show(content, ShareDialog.Mode.NATIVE);
}
I'm calling share(..) method from fragment.
I tried implementing sharing using intents, and that works
Intent shareIntent = new Intent(android.content.Intent.ACTION_SEND);
shareIntent.setType("text/plain");
shareIntent.putExtra(android.content.Intent.EXTRA_TEXT, "http://myUrl.com");
PackageManager pm = activity.getPackageManager();
List<ResolveInfo> activityList = pm.queryIntentActivities(shareIntent, 0);
for (final ResolveInfo app : activityList) {
if ((app.activityInfo.name).contains("facebook")) {
final ActivityInfo mActivity = app.activityInfo;
final ComponentName name = new ComponentName(mActivity.applicationInfo.packageName, mActivity.name);
shareIntent.addCategory(Intent.CATEGORY_LAUNCHER);
shareIntent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK | Intent.FLAG_ACTIVITY_RESET_TASK_IF_NEEDED);
shareIntent.setComponent(name);
activity.startActivity(shareIntent);
break;
}
}
However in my case I need successful share callback, which as much as I know my last solution doesn't provide, since it always return result CANCELED

Have you declared permission for it? Like below:
FacebookSdk.sdkInitialize(getApplicationContext());
callbackManager = CallbackManager.Factory.create();
List<String> permissionNeeds = Arrays.asList("publish_actions"); // permission.
loginManager = LoginManager.getInstance();
loginManager.logInWithPublishPermissions(this, permissionNeeds);
loginManager.registerCallback(callbackManager, new FacebookCallback<LoginResult>() {
#Override
public void onSuccess(LoginResult loginResult) {
// do something here
finish();
}
#Override
public void onCancel() {}
#Override
public void onError(FacebookException exception) {}
});
This is my sample code: https://github.com/minhhuy150894/simple-puzzle/blob/master/app/src/main/java/xyz/davidng/puzzle/FacebookShareImage.java

Facebook is firing onCancel

I was reading the thread: Android Facebook 4.0 SDK How to get Email, Date of Birth and gender of User and I'm using exactly the same code to call a facebook login, but, is always firing the method onCancel, what I'm doing wrong?

I found the error, the error was:

How to create dialog overlay of activity, while user login to facebook?

}
public void loginSuccess(Facebook facebook) {
GraphApi graphApi = new GraphApi(facebook);
User user = new User();
try {
user = graphApi.getMyAccountInfo();
} catch (EasyFacebookError e) {
e.toString();
}
String pkg = getPackageName();
intentResult.putExtra(pkg + ".myName", user.getName());
intentResult.putExtra(pkg + ".myId", user.getId());
startActivity(intentResult);
Intent i = new Intent();
i.putExtra("name", user.getName());
}
}
As you see here the application gives a black backgroud when at this screen to allow the user to log in. What i want to do is, have the log in over top of the main menu. How would i go about doing this?
Integrating it into the main menu activty?

Android is based on stacking Activities, so that's what you should do. You could use startActivityForResult to handle the login Activity and enable your main Activity when a positive result (=succesful login) is returned.
