AndroidManifest.xml中uses-sdk:

<uses-sdk
        android:minSdkVersion="4"
        android:targetSdkVersion="17" />

有警告如下:

Not targeting the latest versions of Android; compatibility modes apply. Consider testing and
 updating this version. Consult the android.os.Build.VERSION_CODES javadoc for details.

作为一个有代码强迫症的人自然是容不得警告的,谷歌一下找到答案,警告的意思是说targetSdkVersion版本不是最新的,改成最新的就可以了.

<uses-sdk
        android:minSdkVersion="4"
        android:targetSdkVersion="18" />
