我正在为我的活动添加谷歌地图。我在谷歌提供的链接中添加了完全相同的代码：https://developers.google.com/maps/documentation/android-api/start?hl=en   但是我的应用程序每次启动时都会崩溃而不显示任何内容。 这是我的Manifest.xml：

<?xml version="1.0" encoding="utf-8"?>

</android.support.design.widget.CoordinatorLayout>

java代码：

package com.example.sachinparashar.mapstrial;

import android.os.Bundle;
import android.support.design.widget.FloatingActionButton;
import android.support.design.widget.Snackbar;
import android.support.v4.app.FragmentActivity;

import com.google.android.gms.maps.SupportMapFragment;
import com.google.android.gms.maps.model.LatLng;
import com.google.android.gms.maps.model.MarkerOptions;

public class map extends AppCompatActivity implements OnMapReadyCallback {

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_map);

    SupportMapFragment mapFragment = (SupportMapFragment) getSupportFragmentManager()
            .findFragmentById(R.id.map);
    mapFragment.getMapAsync(this);

}

public void onMapReady(GoogleMap map) {
    // Add a marker in Sydney, Australia, and move the camera.
    LatLng sydney = new LatLng(-34, 151);
    map.addMarker(new MarkerOptions().position(sydney).title("Marker in Sydney"));
    map.moveCamera(CameraUpdateFactory.newLatLng(sydney));
}
}

这是错误：

build.gradle（模块：app）：

apply plugin: 'com.android.application'

android {
compileSdkVersion 23
buildToolsVersion "23.0.2"

defaultConfig {
    applicationId "com.example.sachinparashar.mapstrial"
    minSdkVersion 17
    targetSdkVersion 23
    versionCode 1
    versionName "1.0"
}

    release {
        minifyEnabled false
        proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'

compile 'com.android.support:design:23.1.1'
compile 'com.google.android.gms:play-services:8.4.0'
}

我现在被困了几个小时。有人可以帮我吗？

您是否在build.gradle中添加了依赖项？如果没有，那么添加它：

  compile 'com.google.android.gms:play-services-maps:8.3.0'

你的build.gradle是这样的：

 buildscript {
    repositories {
        mavenCentral()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:0.5.0'
    }
}
apply plugin: 'android'

dependencies {
    //compile files('libs/android-support-v4.jar')
    compile 'com.google.android.gms:play-services:3.1.36'

}

android {
    compileSdkVersion 17
    buildToolsVersion "17.0.0"

    defaultConfig {
        minSdkVersion 14
        targetSdkVersion 14
    }
}

将此代码添加到Google地图API密钥

上方的清单文件中 
 <meta-data
        android:name="com.google.android.gms.version"
        android:value="@integer/google_play_services_version" />

希望，它会奏效。

试试这个..在运行时添加地图片段在你的Activity / Fragment中。它对我有用。

private void setMap() {
    GoogleMapOptions options=new GoogleMapOptions();
    options.compassEnabled(false);
    mapFragment=SupportMapFragment.newInstance(options);
    getChildFragmentManager().beginTransaction().add(R.id.mapContainer,mapFragment).commit();
    Handler handler=new Handler();
    handler.postDelayed(new Runnable() {
        @Override
        public void run() {
            if(mapFragment!=null){
            googleMap=mapFragment.getMap();
            if(googleMap!=null){
            googleMap.addMarker(new MarkerOptions().position(new LatLng(latitude,longitude))
                    .title(eventBean.getVenueName()).icon(BitmapDescriptorFactory.fromResource(R.drawable.pin)));
            googleMap.animateCamera(CameraUpdateFactory.newLatLngZoom(new LatLng(latitude, longitude),10));
            }
        }
        }
    }, 1000);
}
