Android Build an Interactive Story App (Retired) Intents and Multiple Activities Adding a Second Activity

Can't Add a Second Activity

Because I have several orange highlighted words in my Main Activity (Interactive Story) and hence red squigglies under the names for MainActivity and AndroidManifets tabs at the top, I believe this is stopping me from starting a new activity. The problems appear to be dealing with the mStartButton entry. It says something about being converted to a local variable. I was just told this shouldn't be a problem, but I am stuck.

In my MainActivity: package com.example.twesq.interactivestory;

import android.app.Activity; import android.os.Bundle; import android.view.Menu; import android.view.MenuItem; import android.view.View; import android.widget.Button; import android.widget.EditText; import android.widget.Toast;

public class MainActivity extends Activity {

private EditText mNameField;
private Button mStartButton;

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

    mNameField = (EditText)findViewById(R.id.nameEditText);
    mStartButton = (Button)findViewById(R.id.startButton);

    mStartButton.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            String name = mNameField.getText().toString();
            Toast.makeText(MainActivity.this, name, Toast.LENGTH_LONG).show();


        }
    });
}


}

}

And in my Android Manifest:

<?xml version="1.0" encoding="utf-8"?> <manifest xmlns:android="http://schemas.android.com/apk/res/android" package="com.example.twesq.interactivestory" >

<application
    android:allowBackup="true"
    android:icon="@drawable/ic_launcher"
    android:label="@string/app_name"
    android:theme="@style/AppTheme" >
    <activity
        android:name=".MainActivity"
        android:label="@string/app_name"
        android:screenOrientation=""

        <intent-filter>
            <action android:name="android.intent.action.MAIN" />

            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
    </activity>
</application>

</manifest>

Thanks for the help

delete that set with the word activity, because you have that one below, you just need to have android:screenOrientation="portrait">

OK I got that and now the AndroidManifest is not highlighted. My MainActivity is still red underlined, but I'll try to add a new Activity and see how it goes.

hey, so far, I realized one error in the AndroidManifest file, which is android:screenOrientation=""

you need to input "portrait" between the quotation marks as below android:screenOrientation="portrait" and also close it as below.

android:screenOrientation="portrait">

I wish that helps.

Thanks, I just tried it and I got an other set of <> with the word "activity" in it. Actually this is what it looks like now, and there are a lot more red squigglies.

<?xml version="1.0" encoding="utf-8"?> <manifest xmlns:android="http://schemas.android.com/apk/res/android" package="com.example.twesq.interactivestory" >

<application
    android:allowBackup="true"
    android:icon="@drawable/ic_launcher"
    android:label="@string/app_name"
    android:theme="@style/AppTheme" >
    <activity
        android:name=".MainActivity"
        android:label="@string/app_name"
        android:screenOrientation="portrait"></activity>

        <intent-filter>
            <action android:name="android.intent.action.MAIN" />

            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
    </activity>
</application>

</manifest>

When I hover over the orange highlights I get "Reports empty tag body. The validation works in XML / JSP / JSPX / HTML/ XHTML file types."

My mStartButton is still highlighted orange, but there are no more red squigglies. Thanks again. I'm able to work on the next lesson.
