一、来电归属地没有出来

sprd\packages\apps\InCallUI\src\com\sprd\incallui\geocode\GeocodeHelper.java
private static final String KEY = "ro.device.support.geocode";
private static final boolean SUPPORT_SPRD_GROCODE = SystemProperties.getBoolean(KEY, true) && (OperatorUtils.IS_CMCC || OperatorUtils.IS_CUCC);
//SystemProperties.getBoolean(KEY, true)，获取ro.device.support.geocode的属性值默认为true
//(OperatorUtils.IS_CMCC || OperatorUtils.IS_CUCC):这个sprd本意实现是想判断是联通还是移动，实际打log出来插入移动 OperatorUtils.IS_CMCC获取的值也是false.
private static final boolean SUPPORT_SPRD_GROCODE = SystemProperties.getBoolean(KEY, true); //zxw modify

二、按照一的做了，还是没有出来，

sprd\packages\apps\InCallUI\src\com\android\incallui\CallCardFragment.java@Overridepublic void onViewCreated(View view, Bundle savedInstanceState) {super.onViewCreated(view, savedInstanceState);.../* SPRD: for call geocode @ { */mGeocodeView = (TextView)view.findViewById(R.id.geocode);Log.d("zxw","setPrimary mGeocodeView = " + mGeocodeView);//打log发现mGeocodeView为空，没有显示来电归属地...}

那么在哪里加入mGeocodeView？
还在CallCardFragment.java，onCreateView有加载layout文件

@Overridepublic View onCreateView(LayoutInflater inflater, ViewGroup container,Bundle savedInstanceState) {super.onCreateView(inflater, container, savedInstanceState);mDensity = getResources().getDisplayMetrics().density;View view;// SPRD: add for Universe UIif(SprdUtils.PIKEL_UI_SUPPORT) {view = inflater.inflate(R.layout.call_card_sprd_pikel, container, false);mSimManager = SimManager.get(getActivity());} else if (SprdUtils.UNIVERSE_UI_SUPPORT){view = inflater.inflate(R.layout.call_card_sprd, container, false);mSimManager = SimManager.get(getActivity());} else {view = inflater.inflate(R.layout.call_card, container, false);}return view;}

后面通过分析是走的call_card_sprd_pikel.xml文件，然后在call_card_sprd_pikel.xml会搜到
layout="@layout/primary_call_info_sprd_pikel"/>
所以在primary_call_info_sprd_pikel.xml增加mGeocodeView 控件
sprd\packages\apps\InCallUI\res\layout\primary_call_info_sprd_pikel.xml
加在LinearLayout phoneNumber后面，其实后面发现这样加并不合理，因为屏的分辨率比较小，这样call的状态放到下面去了，看不到了。
后面改成callStateLabel和geocode用LinearLayout包起来，做一行显示

<TextView android:id="@+id/geocode"android:layout_width="wrap_content"android:layout_height="wrap_content"android:layout_gravity="center_horizontal"android:textColor="@color/incall_main_info_text_color_sprd"android:textSize="@dimen/call_status_text_size"android:singleLine="true"/>callStateLabel和geocode用LinearLayout包起来，做一行显示；
<RelativeLayoutandroid:layout_width="wrap_content"android:layout_height="wrap_content"android:layout_gravity="center"><LinearLayoutandroid:layout_width="wrap_content"android:layout_height="wrap_content"android:layout_gravity="center_horizontal"android:orientation="horizontal"><TextView android:id="@+id/geocode"android:layout_width="wrap_content"android:layout_height="wrap_content"android:layout_gravity="center_horizontal"android:textColor="@color/incall_main_info_text_color_sprd"android:textSize="@dimen/call_status_text_size"android:singleLine="true"/><TextView android:id="@+id/callStateLabel"android:layout_width="wrap_content"android:layout_height="wrap_content"android:textSize="@dimen/call_status_text_size"android:textColor="@color/incall_main_info_text_color_sprd"android:layout_marginRight="@dimen/call_button_margin_vertical"android:singleLine="true"android:ellipsize="end"/></LinearLayout><!-- Elapsed time indication for a call in progress. --><TextView android:id="@+id/elapsedTime"android:layout_width="wrap_content"android:layout_height="wrap_content"android:textColor="@color/incall_main_info_text_color_sprd"android:singleLine="true"android:textSize="@dimen/call_status_text_size"android:visibility="gone"android:layout_toRightOf="@id/callStateLabel"/><!-- Call type indication: a special label and/or brandingfor certain kinds of calls (like "Internet call" for a SIP call.) --><TextView android:id="@+id/callTypeLabel"android:layout_width="wrap_content"android:layout_height="wrap_content"android:textColor="@color/incall_main_info_text_color_sprd"android:maxLines="1"android:ellipsize="end"android:visibility="gone" /></RelativeLayout>

三、发现还是没有问题。

sprd\packages\apps\InCallUI\src\com\sprd\incallui\geocode\GeocodeHelper.java
public static void getGeocodeMessage(TextView view, String number) {if (isSupportSprdGeocode()) {Log.d(TAG,"zxw getGeocodeMessage number = " + number);if(!TextUtils.isEmpty(number)){GeocodeAsyncTask task = new GeocodeAsyncTask(view, number);task.execute();}} else {Log.w(TAG, " Can not support sprd geocode !");}}

加个log，发现number为空，导致TextUtils.isEmpty(number)为true,!TextUtils.isEmpty(number)为false,导致GeocodeAsyncTask异步线程没有跑进去。
调试时可以赋值一个number: number = new String(“13510678888”);

然后搜索GeocodeHelper，看在哪里会调用GeocodeHelper的getGeocodeMessage方法

sprd\packages\apps\InCallUI\src\com\android\incallui\CallCardFragment.java@Overridepublic void setPrimary(String number, String name, boolean nameIsNumber, String label,Drawable photo, boolean isConference, boolean isGeneric, boolean isSipCall,boolean isRealNoName, String googleGeocode) {Log.d(this, "Setting primary call");if (isConference) {name = getConferenceString(isGeneric);photo = getConferencePhoto(isGeneric);nameIsNumber = false;}Log.d("zxw","setPrimary mGeocodeView = " + mGeocodeView);/* SPRD: Modify for bug789304 @{ */if (mGeocodeView != null) {Log.d("zxw","setPrimary googleGeocode = " + googleGeocode + ",TextUtils.isEmpty(googleGeocode) = " + TextUtils.isEmpty(googleGeocode));if (!TextUtils.isEmpty(googleGeocode)){mGeocodeView.setVisibility(View.VISIBLE);mGeocodeView.setText(googleGeocode);} else if (GeocodeHelper.isSupportSprdGeocode()) {mGeocodeView.setVisibility(View.VISIBLE);GeocodeHelper.getGeocodeMessage(mGeocodeView, nameIsNumber ? name : number); //zxw }else {mGeocodeView.setVisibility(View.GONE);}}

其实在定义CallCardFragment时，

public class CallCardFragment extends BaseFragment<CallCardPresenter, CallCardPresenter.CallCardUi>implements CallCardPresenter.CallCardUi {sprd\packages\apps\InCallUI\src\com\android\incallui\CallCardPresenter.java 有CallCardUi接口的定义public interface CallCardUi extends Ui {void setVisible(boolean on);void setPrimary(String number, String name, boolean nameIsNumber, String label,Drawable photo, boolean isConference, boolean isGeneric, boolean isSipCall,boolean isRealNoName, String googleGeocode); //Modify for bug789304void setSecondary(boolean show, String name, boolean nameIsNumber, String label,Drawable photo, boolean isConference, boolean isGeneric);void setSecondary(boolean show, String number, String name, boolean nameIsNumber, String label,Drawable photo, boolean isConference, boolean isGeneric);void setSecondaryImage(Drawable image);//@orig setCallState(int, Call.DisconnectCause, boolean, String, String);void setCallState(int phoneId, int state, Call.DisconnectCause cause, boolean bluetoothOn,String gatewayLabel, String gatewayNumber);void setPrimaryCallElapsedTime(boolean show, String duration);void setPrimaryName(String name, boolean nameIsNumber, boolean isRealNoName);void setPrimaryImage(Drawable image);void setPrimaryPhoneNumber(String phoneNumber);void setPrimaryLabel(String label);void displayPhoneView(boolean show);}

在CallCardPresenter.java里会发现

private void updatePrimaryDisplayInfo(ContactCacheEntry entry, boolean isConference) {Log.d(TAG, "Update primary display " + entry);final CallCardUi ui = getUi();if (ui == null || mPrimary == null) {// TODO: May also occur if search result comes back after ui is destroyed. Look into// removing that case completely.Log.d(TAG, "updatePrimaryDisplayInfo called but ui or primary call is null!");return;}final boolean isGenericConf = isGenericConference(mPrimary);if (entry != null) {final String name = getNameForCall(entry);final String number = isConference ? mPrimary.getNumber() : getNumberForCall(entry);final String googleGeocode = getGeocodeForCall(entry);final boolean nameIsNumber = name != null && name.equals(entry.number);Log.d(TAG, "zxw updatePrimaryDisplayInfo number = " + number + ",nameIsNumber" + nameIsNumber + ",isConference" + isConference);ui.setPrimary(number, name, nameIsNumber, entry.label, entry.photo,isConference, isGenericConf, entry.isSipCall, entry.isRealNoName, googleGeocode);//zxw 调用CallCardFragment的setPrimary} else {ui.setPrimary(mPrimary.getNumber(), null, false, null, null, isConference,isGenericConf, false, false, null);}}

在CallCardPresenter.java里会发现，会发现因为已经用了sprd的来电归属，所以GeocodeHelper.isSupportGoogleGeocode()一直为false，没有传递contactInfo.number，而是一个name进去，这就是为什么在前面number为空。换成sprd的
private static String getNameForCall(ContactCacheEntry contactInfo) {
//if (TextUtils.isEmpty(contactInfo.name) && GeocodeHelper.isSupportGoogleGeocode()) {
if (TextUtils.isEmpty(contactInfo.name) && GeocodeHelper.isSupportSprdGeocode()) {//zxw modify
return contactInfo.number;
}
return contactInfo.name;
}

四，这个GeocodeAsyncTask任务跑起来了，但doInBackground里执行cursor = context.getContentResolver().query(uri, new String[] {
“province”, “city”
}, number, null, null);报错

解决：

sprd\packages\providers\ContactsProvider\AndroidManifest.xml
<provider android:name="com.sprd.providers.geocode.GeocodeProvider"android:authorities="gecode_location"android:syncable="false" android:multiprocess="false"android:exported="true">  //之前android:exported="false",允许跨进程通信</provider>

五、读取数据库时，中文为乱码
(1)SQlite中存取的是中文字符时，直接使用cursor.getString读取数据，读出来的数据会出现乱码，此时需要进行一定的转换。
下面是一种有效的读取方法，先以二进制数据从SQLite中读出，再用uft-8对中文进行编码
byte[] procincetemp = cursor.getBlob(cursor.getColumnIndex(“province”));
byte[] citytemp = cursor.getBlob(cursor.getColumnIndex(“city”));
String procince = new String(procincetemp, “utf-8”);
String city = new String(citytemp, “utf-8”);

但是这样就可以正确地显示中文字符，而不是乱码。但需要注意一点就是，这种转换后的字符，结尾多了空格符，需要使用trim函数去除掉
procince = procince.trim();
city = city.trim();

(2)这种方法也可以解决中文字符串乱码
public static String toUtf8(String str) {
String temp = null;
try {
temp = new String(str.getBytes(“UTF-8”), “UTF-8”);
} catch (Exception e) {
e.printStackTrace();
}
return temp;
}
result = toUtf8(result); //将result中文乱码转化为utf-8
