왜 Google지도에서이 오류가 발생합니까? DynamiteLoader를로드하지 못했습니다. java.lang.ClassNotFoundException : 클래스를 찾지 못했습니다.

Question

위도와 경도의 경로를 그려야합니다. 여기 내 MapsActivity.java가 있습니다.

protected void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.activity_maps); 
     // Obtain the SupportMapFragment and get notified when the map is ready to be used. 
     SupportMapFragment mapFragment = (SupportMapFragment) 
getSupportFragmentManager() 
       .findFragmentById(R.id.map); 
     mapFragment.getMapAsync(this); 

     find = (Button) findViewById(R.id.btnFindPath); 
     or = (EditText) findViewById(R.id.etOrigin); 
     dest = (EditText) findViewById(R.id.etDestination); 


     find.setOnClickListener(new View.OnClickListener() { 
      @Override 

      public void onClick(View view) { 

      sendRequest(); 

      } 
     }); 
    } 

    public void sendRequest(){ 

     String origin = or.getText().toString(); 
     String destination = dest.getText().toString(); 

     if(origin.isEmpty()){ 
      Toast.makeText(this,"Please Enter the Origin" , Toast.LENGTH_SHORT).show(); 
     } 

     if(destination.isEmpty()){ 
      Toast.makeText(this,"Please Enter the Destination" , Toast.LENGTH_SHORT).show(); 
     } 

     DirectionFinder directionFinder = new DirectionFinder(origin, destination); 
    } 

    @Override 
    public void onMapReady(GoogleMap googleMap) { 
     mMap = googleMap; 

     /*double array [] = {44.968046 ,-94.420307 ,44.33328,-89.132008, 33.755787,-116.359998,33.844843,-116.54911 ,44.92057 ,-93.44786};

     for (int i = 0 ; i< array.length ; i = i+2){

하지만 오류를 생성 findpath 버튼을 클릭 한 후 : **

** 내 build.gradle (모듈)입니다 :

경로가 그려지지 않았습니다. 지금 할 수 있습니까?

Answer 1

앱의 그라디언트 파일을 다음과 같이 변경하십시오.

이 하나가 build.gradle입니다 (프로젝트 : // 프로젝트 이름)

이 dependenies

// Top-level build file where you can add configuration options common to all sub-projects/modules. 

buildscript { 
    repositories { 
     jcenter() 
    } 
    dependencies { 
     classpath 'com.android.tools.build:gradle:2.2.2' 
     classpath 'com.google.gms:google-services:3.0.0' 
     // NOTE: Do not place your application dependencies here; they belong 
     // in the individual module build.gradle files 
    } 
} 

allprojects { 
    repositories { 
     jcenter() 
    } 
} 

task clean(type: Delete) { 
    delete rootProject.buildDir 
} 

에 classpath 'com.google.gms:google-services:3.0.0'를 추가하고이 일이 당신의 build.gradle에 대한 것입니다 (단위 : 응용 프로그램) 다른 서비스를 사용하지 않는 경우 은지도 단지 파일의 상단이나 하단에 추가 기대 구글에서이 줄을 추가하지 마십시오 apply plugin: 'com.google.gms.google-services'

도움이되기를 바랍니다.
