Firebase google authentication sign in using android

In the project I made on Android studio, I put a button on the user login page to log in with a google account.The account name appears in the Choose an account section.
In the Authentication section, the name does not appear as an account login.The user's mail and password have been entered and saved.When I log into the application with that account, I want it to redirect to the other page, but it does not redirect to the MainActivity2.java page. I would be glad if you could help.
Run:
Connected to process 18504 on device 'emulator-5556'.

Firebase Authentication suddenly stopped working

I have an android app that does not require a log in, but I do have Anonymous sign-in enabled so that I can retrieve the userID from Firebase and use it to log specific events. I have the feeling that it just stopped retrieving the UID from Firebase.
What I've done to resolve the issue is the following:
updated all the dependencies
updated the emulator
Installed a new emulator
re-added the google services plugin
re-added google-services.json file
updated Android Manifest
I've tried to create a login-activity for the sake of testing, where through a button with an onclicklisterer, the user get's anoynmously logged in.
I've doubled checked Local History in Android Studio to see whether big changes were made to the code, not the case. See screenshot
Enabled and disabled anonymous login from the Firebase Console.
Re-written the entire code based on documentation from Firebase.
I've basically tried every solution there is

I've been trying to resolve this issue for over a week now with no success
Edit:
I know I can add listeners to see if the user is anonymously signed in or not. The whole problem around this is that the user is not being signed in anymore at all.

Android cursor = mydatabase.rawQuery breaks app - signal 11

I know that similar questions to this have been asked here before, but this is boggling my mind. I have researched this error and it seems to mostly pop up when you are referencing some part of an array outside its bounds or something, but this error ONLY occurs when I run the app on a virtual device with an API below 23. The machine it fails on is a Galaxy Nexus on API 22, however it also fails on a Nexus 4 with API 22. I tested it also on a virtual Nexus 4 with API 23 and it works, every API above this also works. I want my minimum SDK to be even lower but until I resolve this that will be impossible. Below is some code to help you geniuses see what's driving me insane.
(Cursor resultSet is set globally but it doesn't make a difference)
resultSet = mydatabase.rawQuery("SELECT * FROM words WHERE" + allowRepeats + " frequency >= 0 ORDER BY RANDOM() LIMIT 1",null); -THIS is the line that breaks no matter what I do.
This code renders to "SELECT * FROM words WHERE solved < 1 AND frequency >= 0 ORDER BY RANDOM() LIMIT 1" and this code works on EVERY API above 22, but when running on 22 I get the error "A/libc: Fatal signal 11 (SIGSEGV), code 1, fault addr 0x2c in tid 27273 (ics.choicewords)"
Some notes on what I've tried:
I have made sure that the database does exist and like I said it works on other APIs
I have tried setting the cursor just to null and returning empty strings as the result instead of any data, this works fine but of course is not an option
The rawQuery is run inside a loop that cycles 4 times, but taking it out and just running that single line once still breaks with the same error

I fixed this error a long time ago, so I'm not entirely sure how, but looking back at my old code, it appears the error was created when there were no results that matched the query. I accounted for this afterwards by checking the resultSet count, if it was < 1, I replaced the resultSet with a set of arbitrary values that my app would understand meant no-results. This resolved the issue!

TensorFlowlite Object detection demo app activity(Android studio) won't launch

Trying to tweak the app by launching the DetectorActivity(main activity that does the detection) only when a button is clicked.
So within the source code, I've added a class "Main Activity", set it as the launching activity in the manifest, and in it's xml, added a button that when clicked, should send an intent to the DetectorActivity and launch it. The code is pretty much this :
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
}
public void on(View v){
Intent i = new Intent(this,DetectorActivity.class);
startActivity(i);
}
However, the activity is never launched, which is quite baffling.
Here is the logcat of the emulator:

How are you setting the click listener? This log suggests it's not being called.
The comment by #RyanMentley solved it, thanks a bunch.

HTML content from the web is only partially obtained/displayed

I am running a downloaded tested code from an Android app development course by Rob Percival in Android studio.
The code is for fetching HTML content of a specified URL and displaying it in the logs.
It's the tested code provided by the author of the course.
The code runs fine but only a part of the HTML content of the specified URL is displayed in the logs.
These are the additional log entries I'm getting:
