I can't connect to MySql Database

Why can't I connect to MySQL database?
I tried different codes, I have the jar file mysql-connector-java-5.1.15-bin, but i tried with the: 8.0 version also.
My code:
object DatabaseConnect {
#JvmStatic
fun connection(){
Class.forName("com.mysql.jdbc.Driver").newInstance()
var conn = DriverManager.getConnection(
"jdbc:mysql://sql10.freesqldatabase.com/sql10485647","sql10485647","*********")
}
}
I'm getting this error:

I also had the same issue and I was resolved using the following steps.
It is mainly version issues. Firebase supports only latest versions. if you are using firebase analytics ( implementation 'com.google.firebase:firebase-core:16.0.1'), then we should use latest google services. so you are using 12.0.1, it would not support.
implementation 'com.google.android.gms:play-services-maps:15.0.1'
implementation 'com.google.android.gms:play-services-location:15.0.1'
The above versions resolved my problem.

Solution Found:
Replace classpath 'com.google.gms:google-services:4.0.1' to classpath 'com.google.gms:google-services:3.2.1' in project level build.gradle file.
Update
Solution Found again:
Error came back again after i added some more dependencies. Just Update all dependencies to their latest versions and it will solve the problem.

This error occurs only if RecyclerView or CoordinatorLayout in tab fragment are assigned in xml android id.
In order to identify the error, I wrote an application in which I reproduced it.
https://github.com/RicomenPL/SampleBPE
How to reproduce it?
Enable "dont keep activies" in the development options on the smartphone or emulator
Turn on the SampleBPE application
Move to tabs left or right
Now you have to leave with the Home key
Enter again with the use of the recent apps key
Moving the tabs to the left or right will cause an error

The problem was solved when I downgrade my support libraries to version 26.1.0. This is a temporary solution, to avoid the problem. I hope that in version 28, this will be resolved.

use this dependency this is will solve error
implementation 'com.github.jd-alexander:android-flat-button:v1.1'
use this in code for casting the button
Button btn_CreateNewVideo;
btn_CreateNewVideo = (FButton) findViewById(R.id.createnewvideo);

As of this time the problem occurs in android gradle plugin version 3.0.0. So just change the android gradle plugin version to 2.3.3. You can change it in build.gradle (Project level) file, like:
buildscript {
repositories {
jcenter()
}
dependencies {
classpath 'com.android.tools.build:gradle:2.3.3'
// NOTE: Do not place your application dependencies here; they belong
// in the individual module build.gradle files
}
}

If you have updated your android studio version to 3.o then go to file -> Project Structure -> Project -> Change gradle plugin version to 2.3.0 and gradle version to 3.3
I hope this helps

Same Flat FButton theme can be found here:
Use the library as a dependency https://github.com/jd-alexander/android-flat-button
https://jitpack.io/#jd-alexander/android-flat-button/v1.1
dependencies {
implementation 'com.github.jd-alexander:android-flat-button:v1.1'
}

Another solution I have found
Change for:
Dependence {
implementation 'info.hoang8f:android-segmented:1.0.6'
}
or
You can change casting (FButton) to (Button) with same previous dependency

So, some time ago I've got the exactly same error 'cause my Android Studio Version is higher than the version for which info.hoang8f was implemented, so, step-by-step how to fix it:
In your build.gradle project:level add this line inside allprojects -> repositories: maven { url 'https://jitpack.io' }
In your build.gradle app:level add this line in dependencies: implementation 'com.github.jd-alexander:android-flat-button:v1.1'
Remove the implementation line of 'info.hoang8f...' and Clean Project;
Remember, this new implementation use fButtonColor, so, you need to change in your XML files app:buttonColor='#color/someColor' to: app:fButtonColor='#color/someColor'
Do not:
Change your Gradle Version, this can raise some implementation errors;

SMS Retriever API is available in Google Play Services v10.2 and is used to auto-verify the OTP SMS.
https://developers.google.com/identity/sms-retriever/
This API will not be available in the devices that do not have Google Play Services installed - like Amazon Fire devices or the devices in the Chinese region.
If you are using this API, you have to check whether Play services are installed in the device before accessing this API.
Looking at your exception, it seems this API has been used by some Facebook kit.
