targetSdkVersion设置

Question

如果有人能帮我这个忙的话。我下载了AndroidSDK和安卓编程所需的一切，我在(有趣地)打个招呼的世界上遇到了一些问题。

我只是不了解tarketSdkVersion设置在AppManifest中的作用。每当应用程序没有设置为"13“(刚刚注意到我的minSdkVersion也在工作)，应用程序就有”应用程序停止工作“的屏幕，在LogCat中是这样的：

我不明白，如果这是有意的，我有一些SDK错误或其他东西。我在谷歌上搜索答案，但找不到答案。告诉我，如果我应该添加一些更多的信息，从项目，寻找你的答案。

编辑:忘了添加，我有一个4.4.2 KitKat的安卓设备，所以我想把项目目标设置为20，这就是我注意到这个错误的原因。

EDIT2：

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
}

activity_main.xml：

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:paddingBottom="@dimen/activity_vertical_margin"
    android:paddingLeft="@dimen/activity_horizontal_margin"
    android:paddingRight="@dimen/activity_horizontal_margin"
    android:paddingTop="@dimen/activity_vertical_margin"
    tools:context="pl.bbZoftware.eclipsestandalone.MainActivity" >

    <TextView

        android:layout_centerHorizontal="true"
        android:layout_centerVertical="true"
        android:text="@string/hello_world" />

</RelativeLayout>

Answer 1

我刚发现问题出在哪里。

不要使用API级别为20和平台4.4W，作为Android虚拟设备。在ADV上设置了第19级和4.2.2平台，一切都按应有的方式运行。

Answer 2

只需将android:targetSdkVersion从AndroidManifest.xml中删除

进行以下更改：

<uses-sdk
android:minSdkVersion="8"
android:targetSdkVersion="17" />

至：

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

Answer 3

很可能你在activity_main.xml上犯了错误

也是4.4.2Kitkat的目标是19。在这个android级别页面中检查一下。
