Android Eclipse Fatal Error

Question

Я пытаюсь сделать свое первое приложение с затмением и телефонным разговором. Но когда я пытаюсь запустить приложение, которое я получил это сообщение:

манифеста:

<application android:icon="@drawable/ic_launcher" android:label="@string/app_name" > 
    <activity android:name=".MyFirstAppActivity" 
       android:configChanges="orientation|keyboardHidden|screenSize" 
       android:label="@string/app_name" > 
     <intent-filter> 
      <action android:name="android.intent.action.MAIN" /> 
      <category android:name="android.intent.category.LAUNCHER" /> 
     </intent-filter> 
    </activity>  
</application> 

Я следовал точно инструкциям в http://docs.phonegap.com/en/1.8.1/guide_getting-started_index.md.html#Getting%20Started%20Guides

Вот мой файл MyFirstAppActivity.java:

package my.first.app; 

import android.app.Activity; 
import android.os.Bundle; 
import org.apache.cordova.*; 


public class MyFirstAppActivity extends DroidGap { // DroidGap 
    /** Called when the activity is first created. */ 
    @Override 
    public void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     super.loadUrl("file:///android_asset/www/index.html"); 
    } 
} 

И AndroidManifest.xml

<uses-permission android:name="android.permission.VIBRATE" /> 
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" /> 
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" /> 
<uses-permission android:name="android.permission.ACCESS_LOCATION_EXTRA_COMMANDS" /> 
<uses-permission android:name="android.permission.READ_PHONE_STATE" /> 
<uses-permission android:name="android.permission.INTERNET" /> 
<uses-permission android:name="android.permission.RECEIVE_SMS" /> 
<uses-permission android:name="android.permission.RECORD_AUDIO" /> 
<uses-permission android:name="android.permission.MODIFY_AUDIO_SETTINGS" /> 
<uses-permission android:name="android.permission.READ_CONTACTS" /> 
<uses-permission android:name="android.permission.WRITE_CONTACTS" /> 
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" /> 
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" /> 
<uses-permission android:name="android.permission.GET_ACCOUNTS" /> 
<uses-permission android:name="android.permission.BROADCAST_STICKY" /> 
    <application 
     android:icon="@drawable/ic_launcher" 
     android:label="@string/app_name" > 
     <activity android:name=".MyFirstAppActivity" android:configChanges="orientation|keyboardHidden|screenSize" android:label="@string/app_name" > 
      <intent-filter> 
       <action android:name="android.intent.action.MAIN" /> 
       <category android:name="android.intent.category.LAUNCHER" /> 
      </intent-filter> 

     </activity> 
    </application> 

Answer 1

Возможно, вы забыли объявить MyFirstAppActivity в своем AndroidManifest.xml.

Убедитесь, что ваш манифест содержит что-то подобное в между тегами <application> и </application>:

<activity android:name=".MyFirstAppActivity"> 
    <intent-filter> 
     <action android:name="android.intent.action.MAIN" /> 
     <category android:name="android.intent.category.LAUNCHER" /> 
    </intent-filter> 
</activity> 

Answer 2

Изменить

public class MyFirstAppActivity extends DroidGap { // DroidGap 

в

public class MyFirstAppActivity extends Activity { 

и создать DroidGap объект оттуда если нужно.
