java.lang.RuntimeException: Unable to start activity ComponentInfo{<package-name>/com.google.android.gms.auth.api.signin.internal.SignInHubActivity}

I have received numerous Crashlytics reports of an exception my app is throwing, but I have never seen this myself, and I am struggling to understand where it is coming from.
My running theory is that it is related to the Firebase Auth dependency I have - but that dependency isn't actively being used yet. There is a whole sign-up and sign-in flow that my production app has disabled. The only two instances of the library being used in production code is:
// Inside Activity.onCreate()
Firebase.auth.addAuthStateListener {
val user = it.currentUser
if (user != null) {
Firebase.analytics.setUserId(user.uid)
CoroutineScope(Dispatchers.IO).launch {
registerDeviceToken(applicationContext)
}
} else {
Firebase.analytics.setUserId(null)
Firebase.messaging.deleteToken()
}
}
and:
// Called from Activity.onStart()
fun hasPendingMagicLink(intent: Intent): Boolean {
val emailAddress = getMagicLinkEmailAddress()
return emailAddress != null
&& Firebase.auth.currentUser == null
&& Firebase.auth.isSignInWithEmailLink(intent.data.toString())
}
I have included the Crashlytics reports below.

I want to make a FloatView, but I don't know how to make it only show in the app

I make a FloatView like this site,https://github.com/JackZhous/FloatView
target :
This FloatView will disappear when the user presses the main screen, but the app switch screen will not disappear.
problem :
I modify the file...
FloatUtil.java line 81 mParams.type = WindowManager.LayoutParams.TYPE_PHONE;
->FloatUtil.java line 81 mParams.type = WindowManager.LayoutParams.TYPE_APPLICATION_PANEL;
get error

How can i solve it?

this happen we permission not granted ,WindowManager in android 23 and higher need special permission .
you should add this to mainfest
<uses-permission android:name="android.permission.SYSTEM_ALERT_WINDOW"/>
and use this to make user give you this permission
if(Build.VERSION.SDK_INT >= 23) {
if (!Settings.canDrawOverlays(Activity.this)) {
Intent intent = new Intent(Settings.ACTION_MANAGE_OVERLAY_PERMISSION,
Uri.parse("package:" + getPackageName()));
startActivityForResult(intent, i);
}
}
not that i is integer you will used onActivityResult()

Passing object parameter to extended AsyncTask class

GoodDay everybody.
I wrote a class which extends AsyncTask.
public class InitTransaction extends AsyncTask<TransactionParameters, Void, String> {
#Override
protected String doInBackground(TransactionParameters... params) {
// I do some stuff here
return result;
}
#Override
protected void onPostExecute(String result) {
super.onPostExecute(result);
// I do some more stuff
}
}
The class is called with:
TransactionParameters transParams = new TransactionParameters(param1, param2);
InitTransaction initTransaction = new InitTransaction();
initTransaction.execute(transParams);
The problem is that i get an error while passing the object to the task:
[![No method?][1]][1]
Anybody knows where the problem may be?
EDIT
Fixed that problem now I have another one.
As soon as I execute initTransaction.execute(transParams); boom!

this is the code for the button
private Login login;
public void Loginbutton(View v) {
/* Get entered fields data. */
String email = field_email.getText().toString();
String password = field_password.getText().toString();
login.Logino(new LoginDetails(email,password));
}
when debugging it will run this and go back to the button and after that it will give the exception and crash
public class LoginDetails {
public String email = "";
public String password = "";
LoginDetails(String e, String p) {
email = e;
password = p;
}
}
this is the code I'm trying to run with the button above
public void Logino(LoginDetails loginDetails) {
LoginTask task = new LoginTask();
task.execute(loginDetails);
}

From your StackTrace
Caused by: java.lang.NullPointerException: Attempt to invoke virtual method 'void uk.ac.abertay.contactslist.Login.Logino(uk.ac.abertay.contactslist.LoginDetails)
The line login.Logino the object login is null, you have to initialize it.

Twitter button click crashing app ? Unable to extract the trust manager on okhttp3.internal.Platform$Android

issues is with Twitter button, this is working fine with Android 6 Moto G, while on android 5.0.1 Samsung Note 3 it crashes, on Simulator it works fine too,
However my code for Click is,
TwitterLoginButton twitterLoginButton = (TwitterLoginButton) findViewById(R.id.button_twitter);
twitterLoginButton.setCallback(new Callback<TwitterSession>() {
#Override
public void success(Result<TwitterSession> result) {
Log.d(TAG, "twitterLogin:success" + result);
handleTwitterSession(TwitterAuthProvider.getCredential(
result.data.getAuthToken().token,
result.data.getAuthToken().secret), false);
}
#Override
public void failure(TwitterException exception) {
Log.w(TAG, "twitterLogin:failure", exception);
}
});
twitterLoginButton.setOnClickListener(this);
Issues it is showing is,

i searched a lot on google but unable to find any helpful, solution.

This is a problem with Crittercism. If updating that doesn't help you'll need to report the bug to them.
