Step 3: Describe the problem:

Build gradle sync failed when project run.

// TODO(you): code here to reproduce the problem

Build gradle with :
apply plugin: 'com.android.application'

android {
  compileSdkVersion 24
  buildToolsVersion "24.0.3"
  useLibrary 'org.apache.http.legacy'

  defaultConfig {
      applicationId "com.abc"
      minSdkVersion 16
      targetSdkVersion 24
      versionCode 1
      versionName "1.0"
  }
  buildTypes {
      debug {
          minifyEnabled true
          useProguard false
          proguardFiles getDefaultProguardFile('proguard-android.txt'),
                  'proguard-rules.pro'
      }
      release {
          shrinkResources true
          minifyEnabled true
          proguardFiles getDefaultProguardFile('proguard-android.txt'),
                  'proguard-rules.pro'
      }
  }
}

dependencies {
  compile fileTree(include: ['*.jar'], dir: 'libs')
  testCompile 'junit:junit:4.12'
  compile 'com.android.support:appcompat-v7:24.2.1'
  compile 'com.android.support:design:24.0.0'
  compile 'com.github.bumptech.glide:glide:3.7.0'
  compile 'com.android.support:support-v4:24.2.1'
  compile files('libs/sinch-android-rtc-3.9.9.jar')
  compile 'com.mcxiaoke.volley:library-aar:1.0.0'
  compile 'com.msg91.sendotp.library:library:2.7'
  compile 'org.jbundle.util.osgi.wrapped:org.jbundle.util.osgi.wrapped.org.apache.http.client:4.1.2'
  }
minifyEnabled and shrinker both are creating the same problem again

I don't know I have updated IDE to 2.2.3 but didn't solved anything yet,  my build and compile version are 
buildToolsVersion "24.0.3"
compileSdkVersion 24

@SameerKhan1406 I don't see any firebase dependencies at all in your app so I am going to close this issue as it's not related to this repository. Please let me know if I am mistaken.

It seems the default shrinker has changed. Adding the configuration to turn on ProGuard seemed to work.

buildTypes {
release {
debuggable false
minifyEnabled true
useProguard true
getDefaultProguardFile('proguard-android.txt'),'proguard-rules.pro'
}
debug {
debuggable true
minifyEnabled true
useProguard true
getDefaultProguardFile('proguard-android.txt'),'proguard-rules.pro'
}
}
