Ошибка java 110 - Не ошибается лишь тот, кто ничего не делает!

I’m getting the following error:

frameworks/base/core/java/android/os/mypackage/MyServiceListenerClass.java:283: error 110: Parameter of unavailable type android.os.storage.VolumeInfo in android.os.mypackage.MyServiceListenerClass.myMethod()

I have created a new package with some classes and those classes use VolumeInfo from the storage package.

I couldn’t find any documentation on this error. What have I done wrong?

UPDATE:

Found out that Error 110 = UNAVAILABLE_SYMBOL.

Found this section in doclava/Stubs.java:

for (ParameterInfo p :  m.parameters()) {
    TypeInfo t = p.type();
    if (!t.isPrimitive()) {
      hiddenClass = findHiddenClasses(t);
      if (null != hiddenClass) {
        if (hiddenClass.qualifiedName() == t.asClassInfo().qualifiedName()) {
          // Parameter type is hidden
          Errors.error(Errors.UNAVAILABLE_SYMBOL, m.position(),
              "Parameter of unavailable type " + t.fullName() + " in " + cl.qualifiedName()
              + "." + m.name() + "()");
        } else {
          // Parameter type contains a generic parameter
          Errors.error(Errors.HIDDEN_TYPE_PARAMETER, m.position(),
              "Parameter uses type parameter of unavailable type " + t.fullName() + " in "
              + cl.qualifiedName() + "." + m.name() + "()");
        }
      }
    }
}

So the reason for this error was the @hide attribute at the bottom of VolumInfo‘s documentation part:

/**
 * Information about a storage volume that may be mounted. A volume may be a
 * partition on a physical {@link DiskInfo}, an emulated volume above some other
 * storage medium, or a standalone container like an ASEC or OBB.
 * <p>
 * Volumes may be mounted with various flags:
 * <ul>
 * <li>{@link #MOUNT_FLAG_PRIMARY} means the volume provides primary external
 * storage, historically found at {@code /sdcard}.
 * <li>{@link #MOUNT_FLAG_VISIBLE} means the volume is visible to third-party
 * apps for direct filesystem access. The system should send out relevant
 * storage broadcasts and index any media on visible volumes. Visible volumes
 * are considered a more stable part of the device, which is why we take the
 * time to index them. In particular, transient volumes like USB OTG devices
 * <em>should not</em> be marked as visible; their contents should be surfaced
 * to apps through the Storage Access Framework.
 * </ul>
 *
 * @hide
 */

Removing it solves the issue.

I’m trying to connect client server, where I’m facing below mentioned error while opening connection:

java.net.ConnectException: errno: 110 (Connection timed out), error: 
Connection timed out (local port XXXXX to address 0:0:0:0:0:0:0:0, remote 
port XXXX to address XXX.XXX.XXX.XX)

Code Snippet:

URL url = new URL("http://XXX.XXX.XXX.XX:XXXX/services/ServiceEngine");

HttpURLConnection connection = (HttpURLConnection) url.openConnection();
connection.setDoOutput(true);
connection.setRequestMethod("POST");
connection.setRequestProperty("Content-Type", "application/json");

OutputStreamWriter writer = new OutputStreamWriter(connection.getOutputStream());
writer.write(json);
writer.close();
BufferedReader br = new BufferedReader(new InputStreamReader(connection.getInputStream()));
String line;
while ((line = br.readLine()) != null) {
  jsonString.append(line);
}
br.close();
connection.disconnect();

Connection timeouts happen when the server fails to respond in a pre-determined time period and shouldn’t have much to do with the logic in your code.

You can change this time period with the HttpURLConnection.setConnectTimeout() like this:

connection.setConnectTimeout(10000); //Time is set in milliseconds, so 1000 is 1 second.

Also as another user pointed out it could be that your server isn’t actually up and ready to host connections.

I found that Error 110 = UNAVAILABLE_SYMBOL .

Found this section which is in doclava / Stubs.java:

The reason for this error was the @hide attribute, which is at the bottom of the VolumInfo part of the form:

Welcome to Treehouse!

It appears you are working on the Looping until value passes challenge in the Java Basics course, correct?

If so, and going strictly based on the code you posted, you are missing some line ending semi-colons and other important facets of the challenge.. Additionally, I think you are over-complicating what the task is asking. You can complete the challenge without an if statement, as well as without the creation of a separate Boolean variable.

Something along the lines of:

String who;
do {
console.printf("Knock Knock.n");
who = console.readLine("Who's there?  ");
console.printf("%s who?n", who);
} while(who.equalsIgnoreCase("banana"));

should suffice.

Do you follow along with what the above code is doing?

Happy coding,

Ken

You also missed the «who» variable as your second param in the printf

console.print(«%s who?», who);
