Crash after splashscreen

i'm new at android studio and i'm developing my first app.
Everything worked fine until i implemented a splashscreen. Indeed, when i run the app, the splashcreen works, but then, it crashes.
The thing is that the splashscreen wasn't the first activity i've created (the main). I've created my app and when i finished it, i added a splashscreen.
Actually when i disable the splashscreen (the activity) and start directly with the previous "activity that appears on launch" (that is the "Menu"), it works fine.
And one weird thing: with the splashscreen enabled, it crashes only with certain devices. It runs perfectly with my Xiaomi Redmi Note 5 and a Galaxy S4 (or the nexus 5X emulator) but not with a Galaxy S3 and S6 .
I tried to replace the timer by a simple setonclicklistener button. But same, when it has to load the Menu, it crashes.
I haven't find similar problems on the forums so here i am !
The manifest:
<?xml version="1.0" encoding="utf-8"?>

Thanks by advance for helping me.

In your app gradle make sure that libs use the same version, like:
implementation 'com.android.support:design:28.0.0-alpha1'
implementation 'com.android.support:cardview-v7:28.0.0-alpha1'
implementation 'com.android.support:appcompat-v7:28.0.0-alpha1'
implementation 'com.android.support:gridlayout-v7:28.0.0-alpha1'
You probably don't need all of them.
Make the changes and then click "Sync Now"

Solved it:
I had to add this to the manifest:
android:largeHeap="true"
And it worked fine.

}
}
i need to get red of the blue title bar.

You can remove the title bar forever by calling:
this.requestWindowFeature(Window.FEATURE_NO_TITLE);
before the setContentView(R.layout.x) in your activity class.
To make the app fullscreen, you can do:
getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN);
Again, put the above code before the setContentView method.
And make sure, if you are doing this, you should extend your Activity class by Activity and not AppCompatActivity or any other class.

Problem solved.
Because i didn't continue using the popup window,
i create a new activity instead and make the button redirect from main menu to About activity

attempting multiple activites via button click

I am writing an app that will display a menu of juices at a vape shop.
I have the main screen which displays the name and a button that once clicked will send the user to a new screen displaying the menu.
I am having trouble setting up the button click and when i run the app it crashes after the button is clicked
any input would be appreciated!

The Intent that you are building needs to reference your own Activity classes.
The first parameter is a Context and the second is the Class of the Activity you want to start so it should be the following.
Intent intent = new Intent(this, juiceMenu.class);

Since your question has already been answered, I thought I'd suggest a more efficient means of populating your array to remove that blemish from your code. For example you can use a string-array resource. With that you simply add the values using a single code line. As an example:
String[] juiceArray = getResources().getStringArray(R.array.JuiceTextArray);
The array values themselves are populated in your arrays.xml file (found in values folder) as such:
<resources
xmlns:tools="http://schemas.android.com/tools"
tools:ignore="MissingTranslation">
<string-array name="JuiceTextArray" tools:ignore="MissingTranslation">
<item name="Juice1">#1 Blueberry Bombshell.</item>
<item name="Juice2">#2 Richie Rich.</item>
[etc., etc.]
</string-array>
</resources>

How can I use the square root of a number that the user enters in an input box, instead of the number itself?

I'm trying to make an Android app, and the feature that I'm working on right now is calculating the square root of a number entered by the user.
How can I take a number that the user enters in a text box, and use the square root of that number in the doCalc part of my program? I'm limiting the number to be an integer between 1 and 20. For example, if the user enters 2 in the input box, I want to use 1.41 in the doCalc method.
Here is my .java code:
package learn.text;
import android.app.Activity;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
import android.widget.EditText;
import android.widget.TextView;
public class LearntextActivity extends Activity {
TextView text;
EditText input;
TextView text2;
EditText input2;
TextView text3;
EditText input3;
Button calc;
TextView output;
/** Called when the activity is first created. */
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
text = (TextView) findViewById(R.id.text);
text.setText("Enter the design GPM for Chiller");
input = (EditText) findViewById(R.id.input);
text2 = (TextView) findViewById(R.id.text2);
text2.setText("Enter the Square root of the actual pressure drop across the coil");
input2 = (EditText) findViewById(R.id.input2);
text3 = (TextView) findViewById(R.id.text3);
text3.setText("Enter the design pressure drop of coil");
input3 = (EditText) findViewById(R.id.input3);
calc = (Button) findViewById(R.id.calc);
output = (TextView) findViewById(R.id.output);
}
public void doCalc (View view) {
double mInput = Double.parseDouble(input.getText().toString());
double mInput2 = Double.parseDouble(input2.getText().toString());
double mInput3 = Double.parseDouble(input3.getText().toString());
double mOutput = (mInput*mInput2)/(mInput3);
output.setText("GPM is" + mOutput);
}
}
Here is the .xml file:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical" >
<TextView
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="#string/hello" />
<TextView android:layout_height="wrap_content" android:text="" android:layout_width="wrap_content" android:id="#+id/text"></TextView>
<EditText android:layout_height="wrap_content" android:text="" android:layout_width="match_parent" android:id="#+id/input"></EditText>
<TextView android:layout_height="wrap_content" android:text="" android:layout_width="wrap_content" android:id="#+id/text2"></TextView>

<TextView android:layout_height="wrap_content" android:text="" android:layout_width="wrap_content" android:id="#+id/output"></TextView>
</LinearLayout>
Here is the manifest file:
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"

Probably I'm misunderstanding something, but — can't you just change
Double.parseDouble(input2.getText().toString())
to
Math.sqrt(Double.parseDouble(input2.getText().toString()))
? (See http://docs.oracle.com/javase/7/docs/api/java/lang/Math.html#sqrt(double) for documentation of Math.sqrt.)
