title: Unable to run react native release build for android
body: <p>I have run <code>react-native run-android</code> multiple times to develop the app, on the emulator as well as on the phone but now when i create a release build, the apk is built successfully but when I try to run in on a physical device it crashes immediately with no error log. Running the same release build on the emulator works fine so I'm not sure what the problem is here and its difficult to debug without any crash logs.</p>
  
  <p>Here is my <code>project build.gradle</code> file</p>
  
  <pre><code>buildscript {
      repositories {
          google()
          jcenter()
      }
      dependencies {
          classpath 'com.android.tools.build:gradle:3.1.2'
          classpath 'com.google.gms:google-services:3.2.1'
          // NOTE: Do not place your application dependencies here; they belong
          // in the individual module build.gradle files
      }
  }
  
  
  
  allprojects {
      repositories {
  
  
          google()
          mavenCentral()
          maven { url 'https://jitpack.io' }
  
          mavenLocal()
          jcenter()
          maven {
              // All of React Native (JS, Obj-C sources, Android binaries) is installed from npm
              url "$rootDir/../node_modules/react-native/android"
