title: Can my Android source code be altered to allow users to call functions they arn't allowed to?
body: <p>Suppose I have the following code:</p>
  
  <pre><code>val debug = false 
  
  fun createObj(name: String, latitude: Double, longitude: Double){
      if (!debug) return
      functions = FirebaseFunctions.getInstance()
      functions
          .getHttpsCallable("test")
          .call(hashMapOf(
              "name" to name,
              "latitude" to latitude,
              "longitude" to longitude,
          ))
  }
  </code></pre>
  
  <p>If I push my production code with <code>val debug = false</code>, then in theory, users shouldn't have access to <code>createObj()</code>. </p>
  
  <p>But is there any chance someone can change the value of debug?</p>
