Usage

From source file:Main.java

public static String getBuildInformationAsString() {
    SortedMap<String, String> keysToValues = new TreeMap<String, String>();

    for (String buildField : BUILD_FIELDS) {
        putKeyValue(Build.class, buildField, keysToValues);
    }/*w  w  w.j a  v  a 2s .  c  o m*/
    for (String buildVersionField : BUILD_VERSION_FIELDS) {
        putKeyValue(Build.VERSION.class, buildVersionField, keysToValues);
    }

    StringBuilder stringBuilder = new StringBuilder();
    for (Entry<String, String> entry : keysToValues.entrySet()) {
        stringBuilder.append(entry.getKey()).append(": ").append(entry.getValue()).append('\n');
    }
    return stringBuilder.toString();
