| * Error}, or else as a last resort, wraps it in a {@code DroidDriverException} and then |
| * propagates. <p> This method always throws an exception. The {@code DroidDriverException} return |
| * type is only for client code to make Java type system happy in case a return value is required |
| * by the enclosing method. Example usage: |

| * T doSomething() { |
| * try { |
| * return someMethodThatCouldThrowAnything(); |
| * } catch (IKnowWhatToDoWithThisException e) { |
| * return handle(e); |

| * throw DroidDriverException.propagate(t); |
| * } |

| * @param throwable the Throwable to propagate |
| * @return nothing will ever be returned; this return type is only for your convenience, as |
