Java Eclipse中的升级项目

我们在

Froyo

版本中使用eclipse创建了一个android应用程序，直到

jelly bean 4.2.0

问题是，我们想在

jelly bean 4.2.2

中运行该应用程序。我试着升级

eclpise

中的minSdkVersion和targetSdkVersion，当我在4.2.2我的API中尝试它时，应用程序仍然崩溃，这就是上面的输出。我还进入了

Windows>preferences>android

平台已经有了4.2.2

只需将这一行

android:theme=“@android:style/theme”

添加到AndroidManifest.xml中，如下所示

中的布局XML存在一些问题

<activity
        android:name=".MainActivity"
        android:theme="@android:style/Theme" >
</activity>

你一定在尝试这样的东西：

com.example.javac101.MainActivity.onCreate() at line#69 setContentView()

getWindow（）.setFeatureInt（Window.FEATURE\u CUSTOM\u TITLE，R.layout.）；

但在最新版本的安卓设备中，使用动作栏代替标题

getWindow().setFeatureInt(Window.FEATURE_CUSTOM_TITLE, R.layout.<your layout>);
