我怎样才能解决这个问题？

或如何导入其与包裹的Andr​​oid 4.2.2   探险家，现在它显示andoid L（preVIEW）

在项目属性 - > Android的你一定要选择比Android-L等， 在示例机器人4.4W，因为它们具有相同的API号码 - 的API-20

I have this error in my logcat when imported appcompat v7 from " sdk/extras/android/ "

Platform L is a preview and requires application manifest to set minSdkVersion to 'L'

and the manifest is like

<?xml version="1.0" encoding="utf-8"?>

<manifest xmlns:android="http://schemas.android.com/apk/res/android"
          package="android.support.v7.appcompat">
    <uses-sdk android:minSdkVersion="7"/>
    <application />
</manifest>

how can i resolve this error?

or how can i import it with android 4.2.2 in the package explorer,which now it is showing andoid L(Preview)

In projects Properties -> Android You have to choose other than Android-L, In example Android 4.4W, because they have the same API number - API-20
