Question

I am trying to pass an exception to an activity meant to dump the relevant information to the screen.

Currently I pass it through a bundle:

try {
    this.listPackageActivities();
} catch (Exception e) {
    Intent intent = new Intent().setClass(this, ExceptionActivity.class).putExtra("Exception", e);
    startActivity(intent);
}

But when it gets there:

if (!(this.bundle.getParcelable("Exception") != null))
    throw new IndexOutOfBoundsException("Index \"Exception\" does not exist in  the parcel." + "/n"
    + "Keys: " + this.bundle.keySet().toString());

This sweet exception is thrown but when I look at the keySet and the bundle details it tells me that there is one parcelable object with a key named “Exception”.

I understand that this has something to do with types but I do not understand what I am doing wrong. I just want to dump information about an exception, any exception to the screen. Is there a way to do that without having to condense all the information into a string every time?

I stumbled on this question when I was searching for a method to pass exceptions from a service to an activity. However, I found a better method, you can use the putSerializable() method of the Bundle class.

To add:

Throwable exception = new RuntimeException("Exception");
Bundle extras = new Bundle();
extras.putSerializable("exception", (Serializable) exception);

Intent intent = new Intent();
intent.putExtras(extras);

To retrieve:

Bundle extras = intent.getExtras();
Throwable exception = (Throwable) extras.getSerializable("exception");
String message = exception.getMessage();
