Problem in translation display in translation app on android studio

Hello eveyone i hope you are all doing good. I have a little problem and I couldn't find the solution. I have a translation app and after the user input his phrase by a record, the translation message doesn't appear. So I hope that someone could help me.
Here is my xml file:

android:hint="Tap Mic to Speak"
android:padding="20dp"
android:textColor="#000000"
android:textSize="20sp" />
<Button

Can't find nearby WiFi- Direct devices showing "No Device Found!"

I am trying to Discover two devices each other using WifiDirect. Devices are running Android version 8.0 and 9.0 respectively. But not able to succeed.
First time I click on Discover button on both devices both waits for 2-3 seconds and shows No device found Toast.
Second time I try to discover on both within a second both show up the No device found Toast.

IDK why But you have to enable gps (Location) on both devices.
I have also tested with android version 8 device and android 10 device gps enabled Both are working perfectly fine.

Sorry if there are some formatting errors, I am quite new to Stack Overflow. The code is some testing for a future project. If anyone could answer my question on this error, +1 to you. I would really appreciate the help :)

You need to declare file variable globally.
Like:
private Uri file;
In Java
A variable is a container that holds values that are used in a
Java program. To be able to use a variable it needs to be declared.
Declaring variables is normally the first thing that happens in any
program.

NullPointerException in Android app (Bundle?) [duplicate]

This question already has answers here:
What is a NullPointerException, and how do I fix it?
(12 answers)
Closed 6 years ago.
In a class i am taking we have been learning some android app development and such, and i have managed to run into a problem that I, for the life of me, cannot figure out...
Basic background...
I get a nullpointerexception when I rotate the device... This error is located at Line 100 of QuizActivity.....
this Line is : mCheatButton.setOnClickListener(new View.OnClickListener() {//....
I suspect this has something to do with storing or retrieving information from the bundle...
Anyways here is the rest of The code....
Here is my quiz activity... Sorry for all the code blocks, I dont really know a better way to give you this information, or if you even need all of it.... But right now I just can figure out what is going on... so i have printed the error (stack trace? i think that is the right term...).. here as well...

EDIT: its not a matter of me know what the exception is.. More of the matter of find where and why...

The lookup is failing for mCheatButton because you forgot to assign it an id in the landscape version of the activity_quiz.xml layout file.
When you then try to set a ClickListener on a null object that is where the NullPointerException is coming from.

when you rotate the device,the QuizActivity will destroy and then call onCreate，but your LandLayout file has no Button called 'cheatButton',so findViewById(R.id.cheatButton) will return null to mCheatButton, it can not call any method.

You haven't assigned any id to cheat button in LandLayout - activity_quiz
Change
<Button
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="bottom|center"
android:text="#string/cheat_button"/>
to
<Button
android:id="#+id/cheatButton"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="bottom|center"
android:text="#string/cheat_button"/>
