1. Connect an Android device and run the adb server
2. Run chromedriver.exe latest version (v2.13.307647)
3. Execute the below Java code

DesiredCapabilities capabilities = new DesiredCapabilities();
ChromeOptions chromeOptions = new ChromeOptions();
chromeOptions.setExperimentalOption("androidPackage", "com.android.chrome");
chromeOptions.setExperimentalOption("prefs", new 
JSONObject().put("profile.default_content_settings.geolocation", 2));
capabilities.setCapability(ChromeOptions.CAPABILITY, chromeOptions);
capabilities.setCapability("locationContextEnabled", true);
RemoteWebDriver driver = new RemoteWebDriver(new URL("http://127.0.0.1:9515"), 
capabilities);
driver.manage().timeouts().implicitlyWait(60, TimeUnit.SECONDS);
driver.get("http://baidu.com");

do prefs  this way
        Map<String, Object> prefs = new Hashtable<String, Object>();
        prefs.put("profile.default_content_settings.geolocation", 2);
        // 
        ChromeOptions chromeOptions = new ChromeOptions(); 
        //chromeOptions.setExperimentalOption("androidPackage", "com.android.chrome");      
        chromeOptions.setExperimentalOption("prefs", prefs);  
        //
        DesiredCapabilities capabilities = DesiredCapabilities.chrome(); 
        capabilities.setCapability(ChromeOptions.CAPABILITY, chromeOptions); 
        capabilities.setCapability("locationContextEnabled", true);

With the proposed way, the test runs on the desktop chrome browser and it does 
not go to my connected Android device. I get "error : unrecognized chrome 
option: prefs." if I add this line of code.
chromeOptions.setExperimentalOption("androidPackage", "com.android.chrome");

following work for me on emulator
        Map<String, Object> prefs = new Hashtable<String, Object>();
        prefs.put("profile.default_content_settings.geolocation", 2);
        Map<String, Object> chromeOptions = new HashMap<String, Object>();
        //chromeOptions.setExperimentalOption("androidPackage", "com.android.chrome");  
        chromeOptions.put("androidPackage", "com.android.browser"); 
        chromeOptions.put("androidActivity", "com.android.browser.BrowserActivity");    
        chromeOptions.put("androidDeviceSerial", "emulator-5554");  

    capabilities.setCapability(ChromeOptions.CAPABILITY, chromeOptions); 
        capabilities.setCapability("locationContextEnabled", true);
        //
        capabilities.setCapability("prefs", prefs);

Hi Andrew, I want to invoke com.android.chrome and not com.android.browser like 
in your example. Basically, I want to invoke chrome om my real device and then 
go to "http://www.baidu.com". There, I don't want to see the location prompt. 
So, I modified the code a bit but still that prefs is not applied, I still see 
the location prompt.

Map<String, Object> prefs = new Hashtable<String, Object>();
prefs.put("profile.default_content_settings.geolocation", 2);
Map<String, Object> chromeOptions = new HashMap<String, Object>();
chromeOptions.put("androidPackage", "com.android.chrome");  
capabilities.setCapability(ChromeOptions.CAPABILITY, chromeOptions); 
capabilities.setCapability("locationContextEnabled", true);
capabilities.setCapability("prefs", prefs);  
driver= new RemoteWebDriver(new URL("http://127.0.0.1:9515"), capabilities);

Hi,

1. you would like to invoke chrome browser in a android device? 
2.  open http://www.baidu.com  can not tell what is location prompt.

Sorry, if I confused.

1. I am able to launch chrome on my Android device with the code snippet I 
shared following your suggestion. Thanks. - No issues here.
2. Now, I want chrome to suppress the location prompt in Android device. I 
thought of three options-
    a. Use command line argument for chromedriver.exe - I could not figure out a suitable option or argument to do this.
    b. Use chromeoptions or capability in the code to control this prompt (http://peter.sh/experiments/chromium-command-line-switches/) - I tried the options you suggested with prefs but not working. I still get the location prompt.
    c. Issue 138 had one idea which I was exploring to be able to use for Android chrome but is not working. 

Is it not possible to suppress the location prompt by chrome on Android at all ?

1. can you send(attach) me a screen shot of suppressing the location prompt in 
Android device
2. this won't be chromedriver.exe argument, it will be chrome switch.  Once I 
understand ,  we will figure out

Attached is the screenshot. The screenshot shows the location prompt which I am 
trying to suppress/dismiss but unable to.

I want to suppress/dismiss the prompt which says "http://www.baidul.com wants 
to use your device's location." prompt. These prompts block most of the browser 
window blocking further execution of my script.

   you want to turn off location sharing

1. --enable-strict-powerful-feature-restrictions ⊗    Blocks insecure usage of 
number of powerful features (geolocation, for example) that we haven't yet 
deprecated for the web at large

2. turn off manually -  https://support.google.com/chrome/answer/142065?hl=en

Thanks for the suggestion.

1. I am using below code which suppresses the translate prompt but still does 
not suppress the location prompt (Please refer to my earlier screenshot).

ChromeOptions chromeOptions = new ChromeOptions();
chromeOptions.setExperimentalOption("androidPackage", "com.android.chrome");
chromeOptions.addArguments("--enable-strict-powerful-feature-restrictions");
chromeOptions.addArguments("--disable-translate");
capabilities.setCapability("locationContextEnabled", true);
capabilities.setCapability(ChromeOptions.CAPABILITY, chromeOptions);
driver = new RemoteWebDriver(new URL("http://127.0.0.1:9515"), capabilities);

2. Using similar option as per your suggestion (manual turn off), I am able to 
turn off. But unable to turn on for all sites. There is not such option to turn 
on in Android.

1. this is new to me, need some research.
2. you don't want to turn off for all sites.  only the site you S/W test on?

Thanks for looking into this. I will wait for your research findings.

Strange, why it does not work on the same way on my Android 4.3 device. I am 
using Sony Xperia M C1904 model. It still prompts location.
