title: Issue in communicating with android using Ubidots
body: <p>I enter the two complile lines of code from Ubidots web services. Afterwards I sync the gradle files with the project and attempted to run the program. But an error pops up regarding the App Compact Activity ? The entire android application is functioning.</p>
  
  <pre><code>build.gradle {
  
  apply plugin: 'com.android.application'
  android {
      compileSdkVersion 25
      buildToolsVersion "25.0.2"
      defaultConfig {
          applicationId "com.example.user.mobileapp"
          minSdkVersion 16
          targetSdkVersion 25
          versionCode 1
          versionName "1.0"
          testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
          vectorDrawables.useSupportLibrary = true
      }
      buildTypes {
          release {
              minifyEnabled false
              proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
          }
      }
  }
  
  buildscript {
      repositories {
          jcenter()
      }
      dependencies {
          classpath 'com.android.tools.build:gradle:2.2.3'
          compile 'com.google.code.gson:gson:2.3'
          compile 'com.ubidots:ubidots-java:1.6.4'
  
          // NOTE: Do not place your application dependencies here; they belong
          // in the individual module build.gradle files
      }
  }
