When building an adnroid app, you might stumble upon this error: 

`Failed to finalize session : INSTALL_FAILED_UPDATE_INCOMPATIBLE...`. Here's how to fix it:

That's because the app you're trying to test was already installed on the device and the signatures are different now, so it's complaining. The full error will look like something like this:

`Failed to finalize session : INSTALL_FAILED_UPDATE_INCOMPATIBLE: Package com.example signatures do not match the previously installed version; ignoring!`

You can see that the package ID is `com.example`, well, simply run this command:

tpae

// Trie.js - super simple JS implementation
// https://en.wikipedia.org/wiki/Trie

// -----------------------------------------

// we start with the TrieNode
function TrieNode(key) {
  // the "key" value will be the character in sequence
  this.key = key;
