Dlaczego pojawia się ten błąd, gdy na mapie google "Nie można załadować DynamiteLoader: java.lang.ClassNotFoundException: Nie znaleziono klasy?

Question

Próbuję narysować ścieżkę między dwiema szerokościami geograficznymi, długość geograficzną.Tutaj są moje MapsActivity.java.

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}; 
     // Add a marker in Sydney and move the camera 
     for (int i = 0 ; i< array.length ; i = i+2){ 

      LatLng place = new LatLng(array[i], array[i+1]); 
      mMap.addMarker(new MarkerOptions().position(place).title("Marker in"+ i));

Jednak po kliknięciu przycisku findpath to wygenerowany błąd: **

** mój build.gradle (moduł) wynosi:

apply plugin: 'com.android.application' 

    android { 
     compileSdkVersion 25 
     buildToolsVersion "25.0.0" 

     defaultConfig {

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

i ścieżka nie są rysowane. Co mogę teraz zrobić?

Answer 1

Producent następujące zmiany w Gradle plikach swojej aplikacji.

Ten jest dla build.gradle (Projekt: // Twoja nazwa projektu)

dodać classpath 'com.google.gms:google-services:3.0.0' w 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 
} 

a ten jest dla build.gradle (moduł: app) nie dodawaj tej linii, jeśli nie używasz innych usług Google spodziewać mapy tylko dodać to na górze lub na dole pliku apply plugin: 'com.google.gms.google-services'

Mam nadzieję, że to ci pomoże.
