Android Question Little Help With Some Java please !!

[potman100]

Hi

Not really into java and would like to use this code below in B4A :

public static void printTelephonyManagerMethodNamesForThisDevice(Context context) {

    TelephonyManager telephony = (TelephonyManager) context.getSystemService(Context.TELEPHONY_SERVICE);
    Class<?> telephonyClass;
    try {
        telephonyClass = Class.forName(telephony.getClass().getName());
        Method[] methods = telephonyClass.getMethods();
        for (int idx = 0; idx < methods.length; idx++) {

            System.out.println("\n" + methods[idx] + " declared by " + methods[idx].getDeclaringClass());
        }
    } catch (ClassNotFoundException e) {
        e.printStackTrace();
    }
}

The Following code works and returns the sim state :

 Dim telMgr As JavaObject = GetContext.RunMethod("getSystemService", Array("phone"))
           Dim simState As Int = telMgr.RunMethod("getSimState" , Null)
           Log(simState)

Would appreciate any help.

Regards

Potman

You can include the code in your B4A project by making use of inline Java code. See what I have done here https://www.b4x.com/android/forum/t...ated-with-inline-java-code.53224/#post-337435

It also makes use of the TelephonyManager.

Here it is compiled to a B4A library. Inline java code will probably not work for earlier B4A versions that do not support inline Java so I have compiled it to a library. It prints the result of the library method from within the library to the B4A log. The library files are in the /files folder of the attached project. Copy them to your additional library folder.

This is the result printed to the B4A log:
