Question

I was making a simple text field and ‘send’ button to display whatever the user typed in the text field. The program is completely illustrated in the Android training tutorials by android.com.

Whenever I’m adding the Activity DisplayMessageActivity, I’m getting “Duplicate attribute” as an error. Here’s the code:

<application

      <activity android.name="DroidStart"/>
      <activity
       android:name="com.start.droidstart.DisplayMessageActivity"
        android:label="@string/title_activity_droid" >
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />

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

Update: I fixed the problems that were pointed out, but I’m still getting the error. Here’s my current AndroidMainfest.xml:

<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.start.droidstart"
android:versionCode="1"
android:versionName="1.0" >

<uses-sdk
    android:minSdkVersion="8"
    android:targetSdkVersion="15" />

<application
    android:icon="@drawable/ic_launcher"
    android:label="@string/app_name"
    android:theme="@style/AppTheme" >
      <activity
       android:name="DroidStart"
       android:name="com.start.droidstart.DisplayMessageActivity"
       android:label="@string/title_activity_droid" >
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />

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

The error looks like this

Error parsing XML; duplicate attribute. type Android AAPT problem.

Answer 1

You have at least two errors:

1. Be sure to close your <application> tag.
2. Use android:name, not android.name.

So the first 3 lines should change from:

<application

      <activity android.name="DroidStart"/>

to

<application>

      <activity android:name="DroidStart"/>

Update:

In your updated code, you have:

  <activity
   android:name="DroidStart"
   android:name="com.start.droidstart.DisplayMessageActivity"

You are using android:name twice, which is why you are getting this error. You should probably change this to:

  <activity
   android:name=".DisplayMessageActivity"

assuming DisplayMessageActivity is the class name of the Activity you which to refer to.

Last, you forgot your manifest end tag: you should have </manifest> at the very end of your file.
