ANDROID PAD版本号 PHONE版本号 源代码有什么 差别?

直接把frameworks/base/core/res/res/values/config.xml里面的<bool name="config_voice_capable">false</bool>改为false

    <!-- Flag indicating whether the current device is "voice capable".

         If true, this means that the device supports circuit-switched

         (i.e. voice) phone calls over the telephony network, and is

         allowed to display the in-call UI while a cellular voice call is

         active.  This can be overridden to false for "data only" devices

         which can't make voice calls and don't support any in-call UI.

         Note: this flag is subtly different from the

         PackageManager.FEATURE_TELEPHONY system feature, which is

         available on *any* device with a telephony radio, even if the

         device is data-only. -->
