Ok but, You want to integrate custom package in your appinventor ?

First of all You need to add a textbox that will set the package name

I always say you to look for a while at Appybuilder sources, Only if your builder is not for commercial purposes

See, here they modified it like

github.com

josejad/AppyBuilder/blob/master/AppyBuilder/appinventor-sources/appinventor/common/src/com/google/appinventor/common/utils/StringUtils.java#L24




import java.util.Arrays;
import java.util.Set;


/**
 * Helper class for working with strings.
 *
 */
public final class StringUtils {
  private StringUtils() {
  }


  /**
   * A {@link CharMatcher} that matches valid filename characters:
   * [0-9],[a-z],[A-Z],'_','.', and '-'
   */
  public static final CharMatcher VALID_FILENAME_CHARS =
      CharMatcher.inRange('0', '9')
      .or(CharMatcher.inRange('a', 'z'))
      .or(CharMatcher.inRange('A', 'Z'))
      .or(CharMatcher.is('_'))
