我的应用程序不支持nexus 7

Question

我的清单文件(权限和支持屏幕)如下:

        android:maxSdkVersion="17"
        android:minSdkVersion="10"
        android:targetSdkVersion="17" />

    <permission
        android:name="com.ecw.healow.permission.C2D_MESSAGE"
        android:protectionLevel="signature" />

    <uses-permission android:name="my_app_package.permission.C2D_MESSAGE" />
    <!-- App receives GCM messages. -->
    <uses-permission android:name="com.google.android.c2dm.permission.RECEIVE" />
    <!-- GCM requires a Google account. -->
    <uses-permission android:name="android.permission.GET_ACCOUNTS" />
    <!-- Keeps the processor from sleeping when a message is received. -->
    <uses-permission android:name="android.permission.WAKE_LOCK" />
    <uses-permission android:name="android.permission.INTERNET" />
    <uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />

    <uses-permission android:name="android.permission.CHANGE_WIFI_STATE" />
    <uses-feature android:name="android.hardware.camera" android:required="true"/>
    <supports-screens
        android:anyDensity="true"
        android:largeScreens="true"
        android:normalScreens="true"
        android:smallScreens="true" />

上传到Play商店后,它不会显示nexus-7作为支持的设备.有什么猜测？

Answer 1

虽然Nexus 7有一个前置摄像头,但每个让你的应用程序准备好果冻豆,需要一个摄像头意味着你的应用程序将显示与Nexus 7不兼容.如果你想要Nexus 7兼容性,请设置required ="false".

为确保在启动任何相机相关功能之前可以使用相机,您可以检测设备是否具有相机硬件.
