I have a code like this:

I'm writing an application in the form of instagram (I study lessons from YouTube, they create it on Android 8, I'm trying to do the same on Android 10), I've only known Kotlin for a couple of weeks. Already implemented a lot. But it is with firebase that problems arise. Two questions:

1. Register a user in the application and save his text data in firebase - I can do it from any device. Through the emulator on Android 8 - I can take a picture and everything works as it should, even the link to change the profile photo is displayed correctly. There is also a ShareActivity file where the user can share a photo on the "wall" and the problem is that photos appear in storage in google firebase, and in the realtime database the link to this photo is written as "com.google.firebase.storage.UploadTask $TaskSnapshot@46529a6", but should be written as a link "https://firebasestorage.googleapis.com/v0/b/instapirate...", while the profile photo is displayed correctly, namely posts - no, photos are simply not visible . How to fix this bug? I attach a photo from the emulator and the database:
2. And one more problem, which is that on Android 8 in the Instagram emulator I was asked for permission to the camera, I allowed it and the camera works, takes pictures and everything happens fine. And in android 10, permission to the camera is not requested and, therefore, the camera opens, takes pictures, but cannot save the photos (reopens when I click on the "save" button). A few times if I poke the buttons quickly - sometimes it helps to save the photo, but this happens in one case in a million. Not the fact that this is due to the resolution of the camera. I attach the code below: AndroidManifest

Hey there I'm making a game where you have to guess the name of a song with only the first letters and if you get it wrong once you get more letters twice is game over. (Not finished) But I have run into where my reading of my song csv file doesn't end and loops forever. I have had to end it using the ^C keyboard interrupt. The code works sometimes other times it doesn't.

For this program, I'm trying to use Binary searching to find a specific element of a given array, such as title, year, or artist. For now, I'm only testing for title and year since they are both strings. But it seems that for some of the input I put in, the program would return -1, even though the input I put in exists on the array. I'm not sure why this happens.

First is the tester class, second code is the constructor class.

I tried to use the google auth login code as it is during the splash screen on this site, but I still get a late error

So I made a custom app drawer for my flutter app. but now when I click my open drawer menu button, The first else statement of my widget tree gets executed. I am relatively new to flutter. Does anyone know what I'm doing wrong here?

This is The CustomDrawer Code.

I have a for-loop that returns the data below and I am trying to put it into a single data frame using Pandas. The issue is that each time I try I get separate data frames for each row instead of one single data frame. I'm sure the solution is simple but I just can't work it out.

For-Loop:

I am using ReactJs and React-dom in 17.02 version.

I had the same problem described in this question: a value to increment and decrement using button. I used the solution proposed, changed my previous code.

From this one:

I am working on a project to have a random word guessing game. So far most of the code is working but I am trying to implement some rules on the length of words displayed to the user as a measure of game difficulty (shorter words = easier, etc). I am using a drop-down menu to get the user's setting selection, and then have rules in the JS tags that are supposed to be handling this.

After toying around with this for several days, I was hoping that a fresh pair of eyes might have a suggestion about where I am going wrong to be able to enforce the rules I am trying to enforce?

The specific functions that should be handling this are setDifficulty(), getSelection(), and randomWord()
