Question

noob在这里寻求帮助。

我正在为我的Android应用程序使用Eclipse，为虚拟机使用Bluestacks。

我用按钮创建了一个快速的Android应用程序项目。以下是我的按钮代码：

public void doSomething(View v) {
    Intent i = new Intent(this, com.viva.demo.MainActivity.class);
    startActivity(i);

    /*Intent i = new Intent();
    i.setClassName("com.wodota.test123", "com.viva.demo.MainActivity.class");*/
}

以下是清单文件的代码。

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.wodota.test123"
    android:versionCode="1"
    android:versionName="1.0" >

    <uses-sdk
        android:minSdkVersion="8"
        android:targetSdkVersion="21" />

    <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>
                <action android:name="android.intent.action.MAIN" />
                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
        <activity android:name="com.viva.demo.MainActivity" />
    </application>

</manifest>

我在我的清单文件“com.viva.demo.MainActivity”中包含了一项活动。同样在我的项目中，我已经包含了JAR文件。

下面是我的logcat：

我的应用程序崩溃了。我认为我的清单文件中存在问题。下面是我为Intent Function获得的教程，并且正在运行：
