Answer 1

//删除这个android:targetSdkVersion ="8"

和Nexus 7没有后置摄像头功能.

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

注意:如果您是通过意图使用相机,则您的应用程序无需请求此权限.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,请参阅清单功能参考.将相机功能添加到清单会导致Google Play阻止您的应用程序安装到不包含相机的设备或不支持您指定的相机功能.欲获得更多信息

如果您的应用程序可以使用相机或相机功能进行正确操作,但不需要它,则应在清单中通过包含android:required属性并将其设置为false来指定:

注意:您需要提到支持屏幕

Answer 2

这是因为你的' android.permission.ACCESS_NETWORK_STATE '权限 - 设备没有手机调制解调器,你需要在权限中加入android:required ="false",允许它安装在没有支持它

要控制过滤,请始终在元素中明确声明硬件功能,而不是依靠Google Play"发现"元素中的要求.然后,如果要禁用特定功能的过滤,可以在声明中添加android:required ="false"属性.
