最近我一直在开发一个新应用程序，我正在尝试使用意图添加插件。

我创建了一个名为的小型插件应用程序DLC，我试图在单击按钮时DLC从我的主应用程序启动一个活动。MinePedia

为此，我创建了一个调用活动的意图，DLC但每当我单击按钮时，我都会收到Class not found to handle intent错误消息。

谁能帮我解决这个问题？

体现在DLC

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

    <uses-sdk
        android:minSdkVersion="8"
        android:targetSdkVersion="10" />

    <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" >
            <intent-filter android:label="@string/app_name" android:icon="@drawable/ic_launcher" android:logo="@drawable/ic_launcher">
               <action android:name="com.dlc.MainActivity" />

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


    </application>

</manifest>

MainActivity(MinePedia)

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

     Button button2 = (Button) findViewById(R.id.button1);
        button2.setOnClickListener(new OnClickListener() {          
            public void onClick(View v) {
                startActivity(new Intent(getApplicationContext(), MainActivity2.class));

            }
        });




        Button button9 = (Button) findViewById(R.id.info);
        button9.setOnClickListener(new OnClickListener() {          
            public void onClick(View v) {
                startActivity(new Intent(getApplicationContext(), AppInf.class));

            }
        });




        Button button91 = (Button) findViewById(R.id.dlc);
        button91.setOnClickListener(new OnClickListener() {         
            public void onClick(View v) {

                Intent i=new Intent("com.dlc.MainActivity.class"); startActivity(i);
            }
        });






        Button button96 = (Button) findViewById(R.id.help);
        button96.setOnClickListener(new OnClickListener() {         
            public void onClick(View v) {
                startActivity(new Intent(getApplicationContext(), Instruction.class));

            }
        });



        // this
        String ns = Context.NOTIFICATION_SERVICE;
        NotificationManager mNotificationManager = (NotificationManager) getSystemService(ns);

        int icon = R.drawable.launcher;        
        CharSequence tickerText = "MinecraftPedia"; // ticker-text
        long when = System.currentTimeMillis();         
        Context context = getApplicationContext();     
        CharSequence contentTitle = "MinePedia";  
        CharSequence contentText = "This is the quick launch button for MinePedia";      
        Intent notificationIntent = new Intent(this, MainActivity.class);
        PendingIntent contentIntent = PendingIntent.getActivity(this, 0, notificationIntent, 0);
        Notification notification = new Notification(icon, tickerText, when);
        notification.setLatestEventInfo(context, contentTitle, contentText, contentIntent);

        // and this
        final int HELLO_ID = 1;
        mNotificationManager.notify(HELLO_ID, notification);

}
