Method to set all @Inject fields in a class to mocks:

fun mockInjectables(obj: Any) {
    obj::class.java.declaredFields.forEach { field ->
        field.getAnnotation(Inject::class.java)?.apply {
            if (field.type.isAssignableFrom(dagger.Lazy::class.java)) {
                if (!field.isAccessible) field.isAccessible = true

                val type = field.genericType as ParameterizedType

Root Browser File Manager allows users to copy, move, delete and modify files on internal, external, root and cloud storages. To accomplish this Root Browser requires various permssions as explained below:

Internal Storage Permission:

The Internal Storage on an Android device is often referred to as the SD card. This is not a removable storage.

Root Browser needs the user to grant the WRITE_EXTERNAL_STORAGE permission to work properly. The permission is requested when the app is first launched on Android 6.0+. For previous versions of Android, the permission is granted when the app is downloaded from the Google Play Store.

Android has a way to get the name for a numeric UID using android.os.Process.getUidForName(String name). There is no method to get the numeric id from a UID name. This really ugly reflection will get the numeric UID/GID:

public static String getNameForUid(int id) {
  try {
    Class<?> clazz = Class.forName("libcore.io.Libcore");
    Field field = clazz.getDeclaredField("os");
    if (!field.isAccessible()) {
      field.setAccessible(true);
    }

group symlink:

^\s*(\d+)?\s?([rwxSTstdcb\-lp?]{10})\s+(\d+)?\s?(\S+)\s+(\S+)\s+([0-9,]+)?\s+(\d+)?\s?([0-9\-]{10}\s+[0-9:]{5}|[A-Z][a-z]{2}\s+[0-9]{1,2}\s+[0-9:]{4,5})\s((?:(?!\s\->\s).)*)(\s\->\s)?(.*)

no symlink:

^\s*(\d+)?\s?([rwxSTstdcb\-lp?]{10})\s+(\d+)?\s?(\S+)\s+(\S+)\s+([0-9,]+)?\s+(\d+)?\s?([0-9\-]{10}\s+[0-9:]{5}|[A-Z][a-z]{2}\s+[0-9]{1,2}\s+[0-9:]{4,5})\s(.*)

Using Jsoup:

public static int getGoogleResultsCount(String query) throws IOException {
  String url = "https://www.google.com/search?q=" + query;
  Document document = Jsoup.connect(url)
      .userAgent("Mozilla/5.0 (Windows; U; MSIE 6.0; Windows NT 5.1; SV1; .NET CLR 2.0.50727)")
      .get();
  Element divResultStats = document.select("div#resultStats").first();
 return Integer.parseInt(divResultStats.text().replaceAll("\\D", ""));

Validate Android package name:

The name should be unique. The name may contain uppercase or lowercase letters ('A' through 'Z'), numbers, and underscores ('_'). However, individual package name parts may only start with letters.

^([\p{L}]{1}[\p{L}\p{N}_]*\.)*[\p{L}][\p{L}\p{N}_]*$
