我是为 Android 开发的新手，我在启动我的项目时遇到了麻烦。每当我启动它时，它就会崩溃并出现错误。我已经在我的代码中放置了断点，但它在到达它们之前就崩溃了。这是 LogCat 的输出：

我不知道为什么会发生这种情况，因为它甚至没有在我的代码中遇到断点。一定是自动生成的Android代码有问题。这是我的 AndroidManifest.xml，如果你需要的话：

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

    <uses-permission android:name="android.permission.WAKE_LOCK" />
    <uses-permission android:name="android.permission.BLUETOOTH" />


    <uses-sdk
        android:minSdkVersion="14"
        android:targetSdkVersion="16" />

    <application
        android:allowBackup="true"
        android:icon="@drawable/ic_launcher"
        android:label="@string/app_name"
        android:theme="@style/AppTheme" >
        <activity

            <meta-data
                android:name="android.support.PARENT_ACTIVITY"
                android:value=".ItemListActivity" />
        </activity>
        <activity
            android:name="com.amvara.skatometer.Bottom_panel"
            android:label="@string/title_activity_bottom_panel" >
        </activity>
        <activity

            android:label="@string/title_activity_general" >
        </activity>
          <activity
            android:name="com.amvara.skatometer.SettingsActivity"
            android:label="@string/title_activity_settings" >
        </activity>
    </application>

</manifest>

谢谢。

尝试清理您的项目，然后您还可以更改：

<activity
            android:name="com.amvara.skatometer.ItemListActivity"
            android:label="@string/app_name"
            android:screenOrientation="sensorLandscape" >

[...]
        </activity>

经过

<activity
            android:name=".ItemListActivity"
            android:label="@string/app_name"
            android:screenOrientation="sensorLandscape" >

[...]
        </activity>

它一次附加到我身上，但经过所有修改后，它不起作用，所以我从头开始重新创建项目并导入了我所有的类、布局等。最后，它也能正常工作。
