Emulator in Android mode does not work

pintman

When using the android mode and deploying onto the device directly everything works fine. However, whenever I try to use the emulator, I get the following exception.

Any suggestions might help.

Thanks in advance.

Exception in thread "Thread-31" java.lang.NoSuchMethodError: processing.app.Base.showWarningTiered(Ljava/lang/String;Ljava/lang/String;Ljava/lang/String;Ljava/lang/Exception;)V

I've found using the emulator to be marginal at best. Using a hardware device is entirely superior for both compatibility and performance. If it runs on a hardware device I'd say, be happy. This error is most likely a class definition incompatibility issue and can be hard to track down.

You are right with your comment. However I am a teacher and trying to make a project out of processing and Android. Pupils without a device should be able to use an emulator if they don't own a device by themselves.

Do you know what kind of missing class that could be?

Looking into the source code the problem seems to emerge from the following line of code

https://github.com/processing/processing-android/blob/master/src/processing/mode/android/AVD.java#L133

protected boolean create(final AndroidSDK sdk) throws IOException {
    final String[] params = {
      sdk.getAndroidToolPath(),
      "create", "avd",
      "-n", name,
      "-t", target,
      "-c", DEFAULT_SDCARD_SIZE,
      "-s", DEFAULT_SKIN
    };

    // Set the list to null so that exists() will check again
    avdList = null;

    final ProcessHelper p = new ProcessHelper(params);
    try {
      // Passes 'no' to "Do you wish to create a custom hardware profile [no]"
// System.out.println("CREATE AVD STARTING");
      final ProcessResult createAvdResult = p.execute("no");
// System.out.println("CREATE AVD HAS COMPLETED");
      if (createAvdResult.succeeded()) {
        return true;
      }
      if (createAvdResult.toString().contains("Target id is not valid")) {
        // They didn't install the Google APIs
        Base.showWarningTiered("Android Error", AVD_TARGET_PRIMARY, AVD_TARGET_SECONDARY, null);
// throw new IOException("Missing required SDK components");
      } else {
        // Just generally not working
// Base.showWarning("Android Error", AVD_CREATE_ERROR, null);
        Base.showWarningTiered("Android Error", AVD_CREATE_PRIMARY, AVD_CREATE_SECONDARY, null);
        System.out.println(createAvdResult);
// throw new IOException("Error creating the AVD");
      }
      //System.err.println(createAvdResult);
    } catch (final InterruptedException ie) { }

    return false;
  }

Maybe the target id is not correct.

Some more investigation showed that an AVD named Processing-0217 must be present. I created one with the following line.

./android create avd -n Processing-0217 -t android-10 -c 64M -s WVGA800 --abi x86

Now everything works fine. :)

Glad to see you found the problem. :) It never occurred to me that your install didn't create the required AVD profile for you. I'll have to put this one in my notebook so I'll remember. Cheers.

Great, I had the same problem.

I created the machine from the visual editor: Android > Android AVD Manager. This opens the Android Visual Device Manager.

Settings (I guessed what the command line items signified):

mmm, image upload seems broken...

@kasperkamperman: I think it the image issue has to do with the auto-link-ifier (based on the page source). I was unable to edit your comment to produce an image, but it looks like I can post it here:
