Android Eclipse应用在启动时崩溃

我是Android开发新手，无法启动项目。每当我启动它时，它就会崩溃

这是LogCat的输出：

如果需要，这是我的AndroidManifest.xml：

<supports-screens android:anyDensity="true" android:largeScreens="true" android:normalScreens="true" android:smallScreens="true"/>

<uses-sdk android:minSdkVersion="7" android:targetSdkVersion="14"/>

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

<uses-permission android:name="android.permission.VIBRATE"/>
<uses-permission android:name="android.permission.WAKE_LOCK"/>
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE"/>

<application android:icon="@drawable/icone" android:installLocation="auto" android:label="@string/app" android:launchMode="singleInstance">
    <activity android:configChanges="keyboard|keyboardHidden|orientation" android:name=".Game" android:screenOrientation="portrait" android:theme="@style/Theme.NoBackground">
        <intent-filter>
            <action android:name="android.intent.action.MAIN"/>

            <category android:name="android.intent.category.LAUNCHER"/>
        </intent-filter>
        </activity>
    <!-- Amazon Ads -->
    <activity android:name="com.amazon.device.ads.AdActivity" android:configChanges="keyboardHidden|orientation|screenSize"/>

   <!--  Admob Ads -->
    <meta-data
        android:name="com.google.android.gms.version"
        android:value="@integer/google_play_services_version" />
      <activity
        android:name="com.google.android.gms.ads.AdActivity"
        android:configChanges="keyboard|keyboardHidden|orientation|screenLayout|uiMode|screenSize|smallestScreenSize" />
 </application>

谢谢。

最佳答案

日志说：


原因：android.util.AndroidRuntimeException：requestFeature（）必须
在添加内容之前被调用


换句话说，您已经在requestFeature()中调用setContentView()之后调用了Activity。但这是不可能的。呼叫requestFeature()之前必须先呼叫setContentView()。您尚未发布任何代码，因此我无法真正为您提供更具体的答案。
