I should mention I also have a main2activity.java file like this
[
package com.cancunsteve.aboutcancunsteve;

import android.os.Bundle;
import android.view.Menu;

import android.support.design.widget.Snackbar;
import android.support.v7.app.AppCompatActivity;
import android.support.v7.widget.Toolbar;
import android.view.View;
import android.view.Menu;
import android.view.MenuItem;
import android.view.View.OnClickListener;
import android.widget.Button;

public class Main2Activity extends AppCompatActivity {

@override
protected void onCreate(Bundle savedInstanceState) {
onCreate(savedInstanceState);
setContentView(R.layout.activity_main2);

getSupportActionBar().setDisplayHomeAsUpEnabled(true);
}

}]
this is not sufficient for defining Main2Activity? It should be in main_activity.java as well? thanks

Steven Spiegel · Aug 30, 2018

took your advise and modified my java file mainactivity.java with newactivity2 class
here is the code
[
package com.cancunsteve.aboutcancunsteve;

import android.os.Bundle;
import android.support.v7.app.AppCompatActivity;
import android.view.View;
import android.view.Menu;
import android.view.MenuItem;
import android.view.View.OnClickListener;
import android.widget.Button;
import android.content.Intent;

public class MainActivity extends AppCompatActivity {
Button button;

@override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
// Get the view from activity_main.xml
setContentView(R.layout.activity_main);

// Locate the button in activity_main.xml
button = (Button) findViewById(R.id.MyButton);

// Capture button clicks
button.setOnClickListener(new OnClickListener() {
public void onClick(View arg0) {

// Start NewActivity.class
Intent myIntent = new Intent(MainActivity.this,
NewActivity2.class);
startActivity(myIntent);
}
});
}

@override
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.activity_main, menu);
return true;
}
}

public class NewActivity2 extends AppCompatActivity {
Button button;

@override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
// Get the view from activity_main2.xml
setContentView(R.layout.activity_main2);

Intent myIntent = new Intent(MainActivity.this,
NewActivity2.class);
startActivity(myIntent);
}
});

@override
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.activity_main, menu);
return true;
}
]
the error now is error class, enum expected

Remove });, also you miss a curly braces

Deleted User · Aug 31, 2018

Compiler isn't going to be happy about you declaring two public classes in the same file.
OP, please use code tags to format your code. Thank you.

Steven Spiegel · Aug 31, 2018

yes going through the code I also noticed the braces and removed them. I also fixed other errors. Each time I used the class NewActivity2 it was a mistake and should have been Main2Activity. I repaired the manifest and mainactivity.java in consequence.
the error my compiler gives now is class main2activity is public should be declared in a file named Main2Activity.
which I don't understand as I've done that which you may see it in the two files I will anex below using code tags as you suggest.
the second error is symbol variable activity_main not found
the MainActivity.java file

Code:

public class MainActivity extends AppCompatActivity {
    Button button;

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        // Get the view from activity_main.xml
        setContentView(R.layout.activity_main);

        // Locate the button in activity_main.xml
        button = (Button) findViewById(R.id.MyButton);

        // Capture button clicks
        button.setOnClickListener(new OnClickListener() {
            public void onClick(View arg0) {

                // Start NewActivity.class
                Intent myIntent = new Intent(MainActivity.this,
                        Main2Activity.class);
                startActivity(myIntent);
            }
        });
    }

    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        getMenuInflater().inflate(R.menu.activity_main, menu);
        return true;
    }
}

public class Main2Activity extends AppCompatActivity {
    Button button;

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        // Get the view from activity_main2.xml
        setContentView(R.layout.activity_main2);

                Intent myIntent = new Intent(MainActivity.this,
                        Main2Activity.class);
                startActivity(myIntent);
            }
   
   

    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        getMenuInflater().inflate(R.menu.activity_main, menu);
        return true;
    }
}

now the file Main2Activity.java

Code:

package com.cancunsteve.aboutcancunsteve;

import android.os.Bundle;
import android.view.Menu;

import android.support.design.widget.Snackbar;
import android.support.v7.app.AppCompatActivity;
import android.support.v7.widget.Toolbar;
import android.view.View;
import android.view.Menu;
import android.view.MenuItem;
import android.view.View.OnClickListener;
import android.widget.Button;

public class Main2Activity extends AppCompatActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        onCreate(savedInstanceState);
        setContentView(R.layout.activity_main2);
       

       
        getSupportActionBar().setDisplayHomeAsUpEnabled(true);
    }

}

Thanks so much for taking time to help me. When this is over please allow me to send something to you to show appreciation please.
I see no way around having two public classes?

Steven Spiegel · Aug 31, 2018

you are right. now I recall from a Java book. I changed by MainActivity.java file so instead of public class for Main2Activity it now reads class.
should it be subclass? not sure.
get the error duplicate class in package com.cancunsteve.aboutcancunsteve; in Main2Activity
in my java file Main2Activity.java I do have public class Main2Activity extends AppCompatActivity

wseng92 · Sep 1, 2018

Remove Main2Activity class in MainActivity. It should be fine after this.

Steven Spiegel · Sep 1, 2018

it helped. did that. now just one error: cannot fund symbol variable activity_main
think it is referring to this

Code:

@Override
    public boolean onCreateOptionsMenu(Menu menu) {
        getMenuInflater().inflate(R.menu.activity_main, menu);
        return true;

wseng92 · Sep 1, 2018

This code is refer to res --> menu.

Code:

 getMenuInflater().inflate(R.menu.activity_main, menu);

Check do you have activity_main ?

Deleted User · Sep 1, 2018

You haven't defined the menu correctly in XML. You need to create a file called activity_main.xml under res/menu, containing your options menu items.

https://developer.android.com/guide/topics/ui/menus#options-menu

Steven Spiegel · Sep 1, 2018

I have an activity_main.xml file. but my app has no options menu items. here is my file

activity_main.xml is for your layout, they are totally different things. The menu is used for action bar icon.

Steven Spiegel · Sep 1, 2018

As I have no action bar nor menu, rather than create a file under res/menu, containing your options menu items, can I just remove

Code:

@Override
    public boolean onCreateOptionsMenu(Menu menu) {
        getMenuInflater().inflate(R.menu.activity_main, menu);
        return true;

I believe that segment may be a problem. Got it out of an old book on Java.

Deleted User · Sep 1, 2018

Don't copy/paste code without understanding what it does.

wseng92 · Sep 1, 2018

Steven Spiegel said:

Why not you remove it and tell us the result ?

Steven Spiegel · Sep 1, 2018

did it. now I was able to compile.
my next step is to add an image to the second activity. I've done this before.
your advice helped me on that unnecessary code in the java file.
now a problem adding an image. the image called monument1.jpg is in my mipmap directory
here is my content_main2.xml file

Code:

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"

    app:layout_behavior="@string/appbar_scrolling_view_behavior"
    tools:context="com.cancunsteve.aboutcancunsteve.Main2Activity"
    tools:showIn="@layout/activity_main2">

    <EditText
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:id="@+id/editText6"
        android:layout_alignParentTop="true"
        android:layout_alignParentStart="true"
        android:layout_marginStart="34dp"
        android:layout_marginTop="79dp"
        android:text="look at the photo below. where do you believe I took this photo?" />


<ImageView android:id="@+id/imageView3"
        android:layout_column="1"
        android:background="@mipmap/monument1.jpg"
        android:contentDescription='android:ContentDescription="@string/desc"'
        tools:ignore="HardcodedText"
        android:layout_width="290dp"
        android:layout_height="250dp" />
</RelativeLayout>

can't see why I get the message cannot resolve resource @Mipmap/monument1.jpg
all my images are in the mipmap-xxxhdpi directory

Steven Spiegel · Sep 1, 2018

took out the image to test the app. made a signed app and tried it out on my cel
the only thing in the activity_main2.xml which is my new activity file is a toggle button.
the thing is when I clicked on the button in activity_main.xml to load the second activity, the app crashed.

Deleted User · Sep 2, 2018

Ok, so do you know how to investigate application crashes? I'll start you off here - the first thing you should be doing is looking at the stack trace, which is shown in your Logcat view.

wseng92 · Sep 2, 2018

LV426 is right

Steven, you should learn how to read stack trace. Without stack trace, we can't help.

as running from the command-line is over my head did it through Android Studio: analyze stacktrace.
hope the above gives some clue.
if you need in addition any of my files please let me know and thanks so much people!

That's not a stack trace from a crashed app. You should see an exception message.
You don't need to run the app from the command line.
Run the app from Android Studio, and look at the Logcat view. The stack trace will appear there.

can't see how to get logcat view option in android studio. got a log view while building app that looks like this

Code:

3:47:30 PM Executing tasks: [:app:assembleDebug]
3:48:35 PM Gradle build finished in 1m 4s 171ms
3:48:35 PM Build APK
           APK(s) generated successfully.
           Show in Explorer

triedd view - tood windoes - but no logcat there

by hitting <alt> 6 in studio got logcat but then had trouble with emulator. my anti-virus program blocked it. will try later using my mobile device to run app with logcat on and send results. thanks so much
