How to make the coordinates that located by using the Google Maps Android API (v2) in China correctly display on google map?The type of the coordinates is WGS84 or GCJ02? Any views?
At the moment Google Maps are not officially supported in China. Technically maps are working, but there are 2 major problems for your Chinese customers:
Maps won't work without Google Play Services. Most of the Chinese users do not have them installed.
Google Maps are actually not accurate enough and have some weird offset in coordinates.
What are your options? You will have to use Baidu maps. But the API of their library is different from Google Maps, so to solve the problem you might want to take a look at this library which we wrote: https://github.com/car2go/AnyMaps
Google still has no map publishing license in China (at least as my latest info goes) It may well be that in the near future Google's Map services will be blocked.
A lot of Chinese websites, including ours, use Google's JS as well as their Service API's, Among them is Google's geocoding api. in china, baidu (NASDAQ:BIDU) and sogou [the minor search engine, part of sohu (NASDAQ:SOHU)] both provided online maps and also APIs,
actually, in china, as of now, the google maps api are still available now. as from recent chinatech.us news, Google China passed the annual inspection and got more opportunity to get online map business license so, the 3 API are are and available.

Currently developing an app including google maps, I'm willing to make it work for China as well.
I know the situation in China evolved a bit during the last years. So I would like to know: is it possible to use google maps for an android app in China?
If I attempt to use it as it is directly, the map remains blank, taking probably too long to load or being blocked by the chinese firewall. And my phone has the google services, which is not the case of many other phones.
However, a version of google maps exists in China. See this link: http://www.google.cn/maps?hl=en
So as a part of google is not blocked, would it be possible to load the data of the google maps API for android from the chinese server when the user himself is in China or doesn't have the google services or a VPN?
I finally gave up on google maps and change to GaoDe (amap).
First because Google maps need the googles services, which are not available on Chinese phones.
Then because if there is a way with JavaScript to get to the Chinese google map ( see the following link: developers.google.com/maps/faq?hl=en#china_ws_access ), for android with java it is still not reliable.
Nearly all of the Google service are not working in China.
Most Chinese developer use Baidu or Gaode as the location provider.
i'm developping an android application for tour guide using REST API and Json, so i need to make a map. i don't know what is the best to work with (google map API V2 or API V3 or OpenStreetMap)?? my boss tell me to avoid google map because google can withdraw it at any time.
As far as I know, Google maps v3 is not for Android. And seeing your tags on question, I think it's not an option for you.
As far as Google maps v2 and openStreetMap are concerned, I have always preferred Goole maps because it belongs to same Google Android belongs. So there are (probably) easier integrations and it makes sense to use it especially on Android. Besides, the point that "Google can withdraw it any time" doesn't make any sense to me. Think of the things you use on Android and what if "Google withdraws them".For why openStreetMap is better than Google maps (not from developer's point of view), see this
Founder: OpenStreetMap Already As Good Or Better Than Google Maps
The boss probably told you this, because it is NOT allowed to use the Google API for this purpose because of their terms. See 10.2 d) i)
(d) No Navigation, Autonomous Vehicle Control, or Enterprise Applications. You must not use the Service or Content with any products, systems, or applications for or in connection with any of the following:
(i) real-time navigation or route guidance, including but not limited to turn-by-turn route guidance that is synchronized to the position of a user's sensor-enabled device.
We are using google map android api 2.0 for providing map functionality in our android application.
In our application Google map will be used for capturing and showing location on below use cases .
Whenever a client opens the application (from androiddevice ) depending upon location
services current location will be captured and using reverse geocoding process
appropriate address will be generated.
In reverse flow if any end user wants to enter address manually, using geocoding Service
appropriate location will be showed on the map.
Here are my questions
1>> What is the daily map load(api calls) limit for google map android api 2.0 as there is for google map javascript api 3.0(25k map loads per day)?
2>> What is the geocoding(android.location.Geocoder) limits(No. of geocoding request) per day?we are not using server side geocoding which limit is 2500 free request per day.Does this limit applies to android geocoding(android.location.Geocoder)?
3>> Our app is for government authority and city citizen will be using it,for that can I use google map android api 2.0 or I have to purchase Google Maps Mobile SDK for Business?
4>> what is the difference between Google Maps Mobile SDK for Business and Google Maps Android API 2.0?difference in terms of map loads per day and gecoding limits ?
5>> In what case scenario I should use Google Maps Mobile SDK for Business and Google Maps Android API 2.0?
Any answer clarifying above questions will be really helpful!!!
Thanks in advance
The accepted answer is misleading because although the API console shows no limits on the Maps API, you will be contacted by Google to enable billing or get a Maps for Business licence if the usage of Maps API stays high consistently.
Here are the differences in the usage quotas between the Google Maps Android API and Google Maps API for Business: https://developers.google.com/maps/licensing
Below are the key differences in the SDK of the two APIs:
https://developers.google.com/maps/documentation/business/mobile/android/#comparing_versions
P.S. The SDK comparison table above says that Maps for Mobile SDK is available only as a static library, but if you read the previous paragraph on the same page you can see that you can also get the latest version of Maps for Business SDK through the Android SDK Manager.
I'm a GDE for Google Maps (not Googler), and I asked these questions to the Google Maps team before.
1) No limitation for Google Maps Android API v2.
See the Google APIs Console.
2) I heard no limitation for the android.location.Geocoder from Google Maps team,
because of it's part of Android System.
Read this answer: Android Geocoder quota limits
3) You can use both. But if you want to distribute it without online store, you should contract with the business agreement. Follow the TOS 9.1.2
https://developers.google.com/maps/terms#section_9_1_2
4) There is no support by Google for Google Maps Android API v2.
Read this page.

I'm new to app development and have a few questions related to google maps and places
I am a USA resident and developing an application with a programmer in India which will work on Android and iPhone. I'm wondering if I can use apple maps on iPhone and run Google Places over it. I thought I read paper work saying google places must be run on google maps period. My programming guy said this is fine to do because my app will be free? And we will run google maps on iPhone after we have established people want the app? I will have to upgrade to the business edition of maps once the app hits say 10000 users also which means I can use places over any map.
Can anyone confirm this?
Thanks
James
Google Places API usage must conform to our Terms of Service. And yes, you are correct, you need to display Google Places API results on a Google Map. We have Google Maps SDK for iOS so that should be reasonably easy to accomplish.
Being a free app doesn't absolve you of conforming to our Terms of Service, fwiw.
Using the Google Places API you can search the nearby places of a given co-ordinate. It is true that you can only request around 1000 times for free. Places API doesnt require you to be running any map application ( Apple Maps or Google Maps ). It is simply a WebService hosted by Google from which you get the data back. You can choose to display the data however you want.
Google Maps API V2 for Android is a big leap forward compared to v1: better rendering, fragment support... But there is one grey area I am trying to clarify about its use.
I look forward to create a map-based application for an Android device that does not have Google Play on it i.e. did not pass Google validation such as a low-end tablet or a car radio, and distrbute it on third-party markets.
Such applications using V1 API are possible.
The V2 has a dependency on Google Play Services, which is available to devices with Google Play only.
Does it mean that the V2 API is definitely unavailable for the aforementioned devices?

Only because the makers of those devices pirated the Maps code, as both Maps V1 and Maps V2 are only available for manufacturers who pass validation and license that code.
Does it mean that the V2 API is definitely unavailable for the aforementioned devices?
Barring similar piracy, yes.
You can try manually install the bin files that are required for Google maps, same way as you would do if you wanted to get the emulator running a Google Map API V2.
you can get more information on how it's done from the following blog post I wrote:

I don't know if this solution will be applicable for those devices but you can try it.
