How to find the Android version name programmatically?

As suggested earlier, reflection seems to be the key to this question. The StringBuilder and extra formatting is not required, it was added only to illustrate usage.

import java.lang.reflect.Field;
...

StringBuilder builder = new StringBuilder();
builder.append("android : ").append(Build.VERSION.RELEASE);

Field[] fields = Build.VERSION_CODES.class.getFields();
for (Field field : fields) {
    String fieldName = field.getName();
    int fieldValue = -1;

    try {
        fieldValue = field.getInt(new Object());
    } catch (IllegalArgumentException e) {
        e.printStackTrace();
    } catch (IllegalAccessException e) {
        e.printStackTrace();
    } catch (NullPointerException e) {
        e.printStackTrace();
    }

    if (fieldValue == Build.VERSION.SDK_INT) {
        builder.append(" : ").append(fieldName).append(" : ");
        builder.append("sdk=").append(fieldValue);
    }
}

Log.d(LOG_TAG, "OS: " + builder.toString());

On my 4.1 emulator, I get this output:

D/MainActivity( 1551): OS: android : 4.1.1 : JELLY_BEAN : sdk=16

Enjoy!

Optimized code, this will work:

import java.lang.reflect.Field;

Field[] fields = Build.VERSION_CODES.class.getFields();
String osName = fields[Build.VERSION.SDK_INT + 1].getName();
Log.d("Android OsName:",osName);
