Question

我在我的智慧结束。我正在为我的消防部门开发一个应用程序，并且有一个我可能找不到的错误。我试图从我的第一个活动开始第二个活动，应用程序失败。 Logcat询问我是否已经宣布了我的活动，而且我有。

这是我的清单：

<uses-sdk
    android:minSdkVersion="8"
    android:targetSdkVersion="19" />

<application
    android:allowBackup="true"
    android:icon="@drawable/ic_launcher"
    android:label="@string/app_name">
    <activity android:name="com.HCFD.scenenotes.BrushNotes" />
    <activity
        android:name="com.HCFD.scenenotes.MainActivity"
        android:label="@string/app_name" 
        android:theme="@style/AppTheme">"
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />

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

这是意图：

Intent openBrushNotes = new Intent(this, BrushNotes.class);

以下是我的应用崩溃的电话：

public void openNewNotes(int a){
    Log.i(TAG, "Open New Notes from button " + a);
    switch(a){
    case 1:
        startActivity(openBrushNotes);
        break;

有人能指出我正确的方向，我显然缺少什么？如果重要的话我在Windows 8.1下开发Eclipse ADT

我现在的整个BrushNotes：

package com.HCFD.scenenotes;

import android.app.Activity; import android.os.Bundle;

public class BrushNotes extends Activity {

/** Called when the activity is first created. */
@Override
public void onCreate(Bundle brushBundle) {
    super.onCreate(brushBundle);
    setContentView(R.layout.brush_notes);


}

}

logcat的：
