Answer 1

//去掉这个android:targetSdkVersion="8"

并且 Nexus 7 没有后置摄像头功能。

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

注意:如果您通过 Intent 使用相机，您的应用程序不需要请求此权限。 相机功能 - 您的应用程序还必须声明使用相机功能，例如:

  <uses-feature android:name="android.hardware.camera" />

有关相机功能的列表，请参阅 list 功能引用。 将相机功能添加到您的 list 会导致 Google Play 阻止您的应用程序安装到不包含相机或不支持您指定的相机功能的设备。 For more information

如果您的应用程序可以使用摄像头或摄像头功能进行正常操作，但不需要它，您应该在 list 中通过包含 android:required 属性并将其设置为 false 来指定:

注意:您需要提及supports-screens
