title: React Native: Failed to install on any devices
body: <p>I just started studying React Native. I did all the Android SDK setup and tested everything using Android studio. Using Android Studio, the Hello World app works and runs on my phone with no errors.
  However, I followed every step it takes to run my React Native app on my Android phone:</p>
  
  <ol>
  <li>Enabled USB debugging on my phone</li>
  <li>Checked the "Allow installs from unknown sources" on my phone</li>
  <li>I plugged in my phone and did all the setting about device ID</li>
  <li>But when I run my app (which was created using <code>react-native init AwesomeProject</code>), I get the following error.</li>
  </ol>
  
  <p>When I run <code>react-native run-android</code>, I get this:</p>
  
  <blockquote>
    <p>FAILURE: Build failed with an exception.</p>
    
    <ul>
    <li>What went wrong: Execution failed for task ':app:installDebug'.</li>
    </ul>
    
    <p>Failed to install on any devices.</p>
    
    <ul>
    <li>Try: Run with --stacktrace option to get the stack trace. Run with --info or --debug option to get more log output.</li>
    </ul>
    
    <p>BUILD FAILED</p>
    
    <p>Total time: 1 mins 20.824 secs Could not install the app on the
    device, read the error above for details. Make sure you have an
    Android emulator running or a device connected and have set up your
    Android development environment:

  <p>When I run <code>adb devices</code>, I get this:</p>
  
  <blockquote>
    <p>adb server is out of date.  killing...
    * daemon started successfully * 
    List of devices attached   ????????????   no permissions 
    emulator-5554 device</p>
  </blockquote>
  
  <p>I don't care that the app isn't running even on the emulator-5554 device that seems to have no problem. What I want is for the app to run on my phone which appears to be the app listed as <code>????????????   no permissions</code>. 
  I'll appreciate any help!</p>
