Java: How to get the caller function name

Question

To fix a test case I need to identify whether the function is called from a particular caller function. I can\'t afford to add a boolean parameter because it would break the int

Answer 1

I sometimes want to make some outputs to the logcat. So I wrote a tiny class with some testing-methods:

public class Common {

    // can be used as test-flag anywhere in the app (set to false, when release the app)
    public static boolean b_TEST_MODE = true;

    public static void echo(String message) {
        if (b_TEST_MODE) {
            StackTraceElement[] stackTraceElements = Thread.currentThread().getStackTrace();
            // subtring(25) is to cut off app-name from output
            System.out.println(">>> " + stackTraceElements[3].toString().substring(25) + ": " + message);
        }
    }
}

now you can call it from anywhere in the app to get some infos:

String sSQLQuery = "SELECT * FROM database WHERE id=23";
Common.echo(sSQLQuery);

The logcat prints out:

>>> MainActivity.onCreate(MainActivity.java:46): SELECT * FROM dateabase WHERE id=23
