不幸<app><package>已經停在android emulator-error中，如何解決這個問題？

我是新來android應用程序開發（從昨天我纔開始學習android）。不幸<app><package>已經停在android emulator-error中，如何解決這個問題？

我在AVD中收到消息 - 很不幸停止了，請幫我解決這個錯誤，我想在android中學習更多但被這個錯誤吸住.. plz..plz ..幫我解決這個問題。

我的MainActivity是

public class MainActivity extends Activity { 
protected void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.activity_main); 
    ImageButton mb=(ImageButton) findViewById(R.id.imageButton1); 
    ImageButton mc=(ImageButton) findViewById(R.id.imageButton2); 
    ImageButton me=(ImageButton) findViewById(R.id.imageButton3); 
    ImageButton mf=(ImageButton) findViewById(R.id.imageButton4); 
    ImageButton mg=(ImageButton) findViewById(R.id.imageButton5); 
    ImageButton mh=(ImageButton) findViewById(R.id.imageButton6); 

    mb.setOnClickListener(new OnClickListener() { 

     @Override 
     public void onClick(View v) { 
      // TODO Auto-generated method stub 
Intent activityChangeIntent= new Intent(MainActivity.this,Second.class);    
MainActivity.this.startActivity(activityChangeIntent); 

     } 
    }); 
    mc.setOnClickListener(new OnClickListener() { 

     @Override 
     public void onClick(View v) { 
      // TODO Auto-generated method stub 
      startActivity(new Intent(MainActivity.this,Second.class)); 

     } 
    }); 


      me.setOnClickListener(new OnClickListener() { 

    @Override 
    public void onClick(View v) { 
     // TODO Auto-generated method stub 
     startActivity(new Intent(MainActivity.this,Second.class)); 

    } 
}); 



     mf.setOnClickListener(new OnClickListener() { 

    @Override 
    public void onClick(View v) { 
     // TODO Auto-generated method stub 
     startActivity(new Intent(MainActivity.this,Second.class)); 

    } 
}); 
    mg.setOnClickListener(new OnClickListener() { 

    @Override 
    public void onClick(View v) { 
     // TODO Auto-generated method stub 
     startActivity(new Intent(MainActivity.this,Second.class)); 

    } 
}); 


      mh.setOnClickListener(new OnClickListener() { 

    @Override 
    public void onClick(View v) { 
     // TODO Auto-generated method stub 
     startActivity(new Intent(MainActivity.this,Second.class)); 

    } 
}); 


} 

}

我的MainActivity XML是：

MY logcat的是：

我的第二個活動是

public class Second extends Activity{ 
@Override 
protected void onCreate(Bundle savedInstanceState) { 
    // TODO Auto-generated method stub 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.mpage); 
    } 
    }

我的第二個活動XML是：

<?xml version="1.0" encoding="utf-8"?> 
    <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" 
    android:layout_width="match_parent" 
    android:layout_height="match_parent" 
    android:orientation="vertical" > 

    <TextView 
    android:id="@+id/textView1" 
    android:layout_width="wrap_content" 
    android:layout_height="wrap_content" 
    android:text="@string/TextView" /> 

    </LinearLayout>

你好請加你的清單。 :) –

直接從logcat的：

android.content.ActivityNotFoundException: Unable to find explicit activity class {com.somayaji.abhi/com.somayaji.abhi.Second}; have you declared this activity in your AndroidManifest.xml?

你忘了在清單xml文件中聲明您的Second活動。

嘗試閱讀logcat，消息通常非常豐富，您可以更快地糾正錯誤，而不是在此處發佈。

雅...它解決了謝謝... – somayaji

@somayaji如果答案有助於標記這個答案被接受 – Raghunandan

宣佈第二個活動

<activity android:name="com.somayaji.abhi.Second" > 
</activity>

清單文件

檢查主題將它添加到表現

這是一個ActivityNotFound例外。

包括

<activity android:name="com.somayaji.abhi.Second" > 
</activity>

您的清單文件中的應用標籤內。
