솔루션

1、`

android {
    	packagingOptions {
	        exclude 'META-INF/LICENSE'
        	exclude 'META-INF/NOTICE'
        	exclude 'META-INF/rxjava.properties'
        	exclude 'META-INF/rxandroid.properties'
   			 }
    	}

2、

defaultConfig {
        multiDexEnabled true
    }

3、`

dependencies {
			configurations {
     		   /*all*.exclude group: 'com.squareup.okhttp3', module: 'okhttp'
       		 all*.exclude group: 'com.squareup.okio'*/
        	 all*.exclude group: 'com.squareup.okhttp3'
      	  	 all*.exclude group: 'com.squareup.okio'
    		}
	}

4. jar 인용의 선후 순서를 조정한다.
5. AndroidStudio 콘솔에서 다음을 입력합니다.

gradlew -q app:dependencies  

의존 관계를 확인한 후 불필요한 의존jar 패키지를 삭제합니다.
