I'm trying to implement twitter login in my android app.
I've followed the instructions ( https://dev.twitter.com/twitter-kit/android/twitter-login ).
Everything is working fine if I have the twitter app installed but if I don't when I tap on the login button I get the exception below.
It shoulw open a webview asking to login instead.
Any hint?

Here there is my code:
AndroidManifest.xml:
<meta-data
android:name="io.fabric.ApiKey"
android:value="XXXXXXXX" />
MainActivity.java:
TwitterAuthConfig authConfig = new TwitterAuthConfig(TWITTER_KEY, TWITTER_SECRET);
Fabric.with(this, new Twitter(authConfig), new Crashlytics()); //I've tried without crashlytics, same problem. Crashlytics works..
LoginActivity.java:
loginButton = (TwitterLoginButton) findViewById(R.id.twitter_login_buttons);
loginButton.setCallback(new Callback<TwitterSession>() {
#Override
public void success(Result<TwitterSession> result) {
Log.d(TAG, "Success");
}
#Override
public void failure(TwitterException exception) {
Log.d(TAG, "Failure");
}
});
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
loginButton.onActivityResult(requestCode, resultCode, data);
}
I've found a solution:
it is a breaking change in okhttp 2.4, reverting to 2.3 solved my problem.

I am getting this error after selecting a google account. OnActivityResult is called, but after evaluating the result this error is thrown. The cause is not a wrong SHA1, I am using the same key for release and debug. The app is not from Google Play. I am not using firebase. The google signin sample works with the same key.

In case this helps anybody: I was in this situation, except that it worked initially then stopped working later. I finally realized that it was because I switched laptops.
The solution is the package name: The package name of the manifest is de.org.limindo.limindo2 but the package of the apk is de.org.limindo2 ..... It seems that gradle shortens package names, if they contain double entries….
I'm getting this fatal exception: main error. It is only when I click on the 'Pick A Place' button on my app.

The ToDo was automatically generated when Android Studio automatically added the '#TargetAPI' bit. With this in mind I added the following to the manifest and as I got no more errors I thought this would be enough:
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
However, the app just crashes.
Any help greatly appreciated.

Extending AppCompatActivity will solve the issue.
Do like this
public class SettingsActivity extends AppCompatActivity {
I have a AsyncTask in a Service. I send an ArrayList as broadcast from the AsyncTask.
When I get the ArrayList in onReceive() I get a NullpointerException.
This is how I send the ArrayList.
transits_list = new ArrayList<Transit>();
transits_list.add(trs);
Intent arrayListIntent = new Intent("arrayList");
Bundle extra = new Bundle();
extra.putSerializable("transArray", transits_list);
intent.putExtra("extra", extra);
sendBroadcast(arrayListIntent);
The Transit class implements Serializable.
Receiving the ArrayList
#Override
public void onReceive(Context context, Intent intent) {
ArrayList<Transit> myList;
Bundle extra = getIntent().getBundleExtra("extra");
ArrayList<Transit> transArrayListFromBroadCast = (ArrayList<Transit>) extra.getSerializable("transArray");
System.out.print("transArrayListFromBroadCast "+transArrayListFromBroadCast);
}
I get NullpointerException in this line:
ArrayList<Transit> transArrayListFromBroadCast = (ArrayList<Transit>) extra.getSerializable("transArray");
The exception from log:

Your method of getting the Intent is incorrect. I believe your BroadcastReceiver is in an activity class since, you are calling getIntent(). However, getIntent() will get you the Intent supplied to the activity and not the receiver. The Intent for receiver is provided to the method onReceive() itself. Make the following changes to your code:
Adding extra:
Intent arrayListIntent = new Intent("arrayList");
Bundle extra = new Bundle();
extra.putSerializable("transArray", transits_list);
intent.putExtra("extra", extra);
sendBroadcast(arrayListIntent);
Getting Extra:
#Override
public void onReceive(Context context, Intent intent) {
ArrayList<Transit> myList;
Bundle extra = intent.getBundleExtra("extra");
ArrayList<Transit> transArrayListFromBroadCast = (ArrayList<Transit>) extra.getSerializable("transArray");
// System.out.print("transArrayListFromBroadCast "+transArrayListFromBroadCast);
}
I am getting this error when hitting the "Login With Facebook" (Simple login button).
I have Google, and read other topics here - but I can not see any thing matching my issue.
I am adding Login.java class below.
public class Login extends Activity {
/**
* Called when the activity is first created.
*/
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
FacebookSdk.sdkInitialize(getApplicationContext());
setContentView(R.layout.activity_login);
CallbackManager callbackManager = CallbackManager.Factory.create();
LoginButton loginButton = (LoginButton) findViewById(R.id.login_button);
loginButton.setReadPermissions("public_profile", "email", "user_friends");
// Other app specific specialization
loginButton.registerCallback(callbackManager, new FacebookCallback<LoginResult>() {
#Override
public void onSuccess(LoginResult loginResult) {
Log.i("Login", "Logged in: ");
Intent i = new Intent(Login.this, MainActivity.class);
startActivity(i);
}
#Override
public void onCancel() {
// App code
}
#Override
public void onError(FacebookException exception) {
// App code
Log.i("Error" , "Error");
}
});
}
}

Check your android:noHistory flag on the activity.
See link
https://developers.facebook.com/bugs/1621984714705591/
look for post by Andreas Bergenwall
This can happen when the user has the native Facebook App installed.
You can suppress the attempt to open it by initializing the LoginManager's LoginBehaviour:
// Don't allow the Facebook App to open.
LoginManager.getInstance().setLoginBehavior(LoginBehavior.WEB_VIEW_ONLY);
I too had this issue. Mine however was a login call made within the FBActivity.OnResume method for callbacks to login after accepting fb perms.
I simply moved the request into the profile tracker in the onCreate method
ProfileTracker profileTracker = new ProfileTracker() {
#Override
protected void onCurrentProfileChanged(Profile oldProfile, Profile currentProfile) {
Profile.fetchProfileForCurrentAccessToken();
if(currentProfile != null) {
String fbUserId = currentProfile.getId();
profileUrl = currentProfile.getProfilePictureUri(200, 200).toString();
Log.d("FB profile", "got new/updated profile from thread " + fbUserId);
// jump if logged in already
GetFacebookProfileAndJump(currentProfile);
}
}
};
Also ensure your OnCreate super is as follows
FacebookSdk.sdkInitialize(getApplicationContext());
mCallbackmanager = CallbackManager.Factory.create();
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_fbauth_);
...
You should add this to your acctivity
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
callbackManager.onActivityResult(requestCode, resultCode, data);
}
but if your using parse SDK add this
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
ParseFacebookUtils.onActivityResult(requestCode, resultCode, data);
}
I had the same problem, and solved by putting the facebook_app_id to strings.xml instead of a constant:
<meta-data
android:name="com.facebook.sdk.ApplicationId"
android:value="#string/facebook_app_id" />
In my case i forgot to add application package name and class name on the developer page of facebook. After i added this information then it worked.
I have struggled with this problem and I fixed with multidex enabled
add this in your build file
multiDexEnabled true
also this code in your activity
#Override
protected void attachBaseContext(Context context) {
super.attachBaseContext(context);
MultiDex.install(this);
}
after adding this in your build gradle dependencies
compile 'com.android.support:multidex:1.0.1'
Actually this is happend. Because of the onActivityResult method has not implemented in side your Activity and also you must call
callbackManager.onActivityResult(requestCode, resultCode, data);
method inside this method. I am sure 100% your problem resolved.
First of all, sorry for my bad English !
I have an Activity ( say MainActivity.java ) and a class ( say AsynkTaskClass.java ).
AsynkTaskClass.java contains an AsynkTask. I am calling this AsynkTask from MainActivity.java.
Before calling this AsynkTask, I am saving some data using SharedPreferences.
From the onPostExecute function of AsynkTask, I am calling a normal function ( say displaySharedData() )which defined in MainActivity.java. There I am trying to retrieve the data I stored using SharedPreferences. Then It shows a NullPointerException. But I can access the Shared data from anywhere other than this displaySharedData() function.
This is the Log Output:

}
mainActvtyObj.displaySharedData();
}
}
So, Any Help ??
MainActivity mainActvtyObj = new MainActivity();
Never instantiate activity classes with new.
For example, their lifecycle callbacks such as onCreate() are not run. You init your myData in onCreate() and it remains null in this activity instance.
Instead, pass a reference to your activity object to the async task as a parameter.
Finally I got a working solution.
I don't know whether It is perfect! But it works well..
I replaced the displaySharedData() calling statement i.e. mainActvtyObj.displaySharedData(); to the following :
((MainActivity) s3context).displaySharedData();
Now It Works Great !!
