由于Android系统的WiFi模块不支持wifi direct功能，所以要删除显示里的屏幕投射功能选项。

位置是设置——显示——屏幕投射

代码修改如下：

niming@ubuntu:/home/user/workspace2/niming/a33-v2.0/android/packages/apps/Settings$ git diff   src/com/android/settings/DisplaySettings.javadiff --git a/src/com/android/settings/DisplaySettings.java b/src/com/android/settings/DisplaySettings.javaindex 3f1b39e..97e0596 100755--- a/src/com/android/settings/DisplaySettings.java+++ b/src/com/android/settings/DisplaySettings.java@@ -181,6 +181,7 @@ public class DisplaySettings extends SettingsPreferenceFragment implements             mMiracastFullScreen.setOnPreferenceChangeListener(this);             mMiracastControlPreference.setDependency(KEY_MIRACAST_FULL_SCREEN);         }+        getPreferenceScreen().removePreference(mWifiDisplayPreference);         mBrightSystem = (CheckBoxPreference)findPreference(KEY_BRIGHT_SYSTEM);         mBrightSystemDemo = (CheckBoxPreference)findPreference(KEY_BRIGHT_SYSTEM_DEMO);         boolean demoEnabled;
