1.模块编译的添加修改device/sprd/sp8830ec/system.prop 中ro.device.support.gps=1

2.Settings模块中packages/apps/Settings/src/com/android/settings/LocationSettings.java文件中修改打开GPS功能

public class LocationSettings extends SettingsPreferenceFragment
mLocationAccess.setOnPreferenceChangeListener(this);

     if(!getPackageManager().hasSystemFeature(PackageManager.FEATURE_LOCATION_GPS)) {
             root.removePreference(mGps);
             root.removePreference(mAssistedGps);
             root.removePreference((PreferenceScreen) root.findPreference(KEY_AGPS_CONFIG));
         }
3.Settings模块packages/apps/Settings/res/layout/widget.xml对应的widget中添加对应的控件。

   <ImageView
         android:layout_width="1dip"
         android:layout_height="match_parent"
         android:background="@drawable/appwidget_settings_divider_holo"
         android:contentDescription="@null"
         />

     <LinearLayout
         android:background="@drawable/appwidget_button_center"
         android:clickable="true"
         android:focusable="true"
         android:orientation="vertical">
         <ImageView
             android:contentDescription="@null"
             />
     </LinearLayout>

添加模块gpstest

9.添加package/app/gpstest源码修改Android.mk去掉依赖的jar。
10.settings模块添加入口到
<PreferenceScreen
                android:key="gps_test"
                android:title="@string/gps_test">
            <intent android:action="android.intent.action.MAIN"
                    android:targetPackage="com.android.gpstest"
                    android:targetClass="com.android.gpstest.GpsTestActivity" />
       </PreferenceScreen>
