How to I identify the device on which android tests are currently running?

Question

I have multiple devices connected and I run the gradle command 'connectedCheck' which runs tests on multiple devices.

ConnectedCheck executes tests on all the devices in an order. I want to get the serial number of the device the tests are currently being run on.

Does android provide a way to do that?

You can get lots of details of your android device like :

//Get the instance of TelephonyManager  
    TelephonyManager  tm=(TelephonyManager)getSystemService(Context.TELEPHONY_SERVICE);  

    //Calling the methods of TelephonyManager the returns the information  
    String IMEINumber=tm.getDeviceId();  
    String subscriberID=tm.getDeviceId();  
    String SIMSerialNumber=tm.getSimSerialNumber();  
    String networkCountryISO=tm.getNetworkCountryIso();  
    String SIMCountryISO=tm.getSimCountryIso();  
    String softwareVersion=tm.getDeviceSoftwareVersion();  
    String voiceMailNumber=tm.getVoiceMailNumber();  

    //Get the phone type  
    String strphoneType="";  

    int phoneType=tm.getPhoneType();  

    switch (phoneType)   
    {  
            case (TelephonyManager.PHONE_TYPE_CDMA):  
                       strphoneType="CDMA";  
                           break;  
            case (TelephonyManager.PHONE_TYPE_GSM):   
                       strphoneType="GSM";                
                           break;  
            case (TelephonyManager.PHONE_TYPE_NONE):  
                        strphoneType="NONE";                
                            break;  
     }  

And to get the device model name, we use:

public String getDeviceName() {
String manufacturer = Build.MANUFACTURER;
String model = Build.MODEL;
if (model.startsWith(manufacturer)) {
    return capitalize(model);
} else {
    return capitalize(manufacturer) + " " + model;
}
}


private String capitalize(String s) {
if (s == null || s.length() == 0) {
    return "";
}
char first = s.charAt(0);
if (Character.isUpperCase(first)) {
    return s;
} else {
    return Character.toUpperCase(first) + s.substring(1);
}
}

I found the solution! In fact there wasn't a problem in the first place.

Issue: Gradle android plugin's task to run tests is 'connectedCheck'. It executes tests on how many ever android devices connected to a host. Now when I @Ignore a test it will be ignored on all those devices where as I wanted to do that only for the failing device/devices

Solution: Add a custom jUnit annotation that takes an array of String values for Device serial IDs. Write a custom test runner by extending BlockJUnit4ClassRunner override runChild to check if Build.Device is same as the one provided in the annotation if a method is annotated.

If it is fireTestIgnored to ignore so that it will be skipped only for the device you specified in the annotation.
