Android firebase与Google Maps集成

I am trying to integrate my firebase database with Google Maps but I am having issues. Here is my code:

我正在尝试将我的firebase数据库与Google Maps集成,但我遇到了问题。这是我的代码:

package com.test.googlemap;

import android.Manifest;
import android.content.pm.PackageManager;
import android.location.Criteria;
import android.location.Location;
import android.location.LocationManager;
import android.support.v4.app.FragmentActivity;
import android.os.Bundle;

import com.firebase.client.DataSnapshot;
import com.firebase.client.Firebase;
import com.firebase.client.FirebaseError;
import com.firebase.client.ValueEventListener;
import com.google.android.gms.common.api.GoogleApiClient;
import com.google.android.gms.location.LocationServices;
import com.google.android.gms.maps.CameraUpdateFactory;
import com.google.android.gms.maps.GoogleMap;
import com.google.android.gms.maps.OnMapReadyCallback;
import com.google.android.gms.maps.SupportMapFragment;
import com.google.android.gms.maps.UiSettings;
import com.google.android.gms.maps.model.LatLng;
import com.google.android.gms.maps.model.MarkerOptions;



public class MapsActivity extends FragmentActivity implements    OnMapReadyCallback {

private static GoogleMap mMap;
private GoogleApiClient mGoogleApiClient;



@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    Firebase.setAndroidContext(this);
    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);

    /*if (mGoogleApiClient == null) {
        mGoogleApiClient = new GoogleApiClient.Builder(this)
                .addConnectionCallbacks(this)
                .addOnConnectionFailedListener(this)
                .addApi(LocationServices.API)
                .build();
    }*/
}


/**
 * Manipulates the map once available.
 * This callback is triggered when the map is ready to be used.
 * This is where we can add markers or lines, add listeners or move the camera. In this case,
 * we just add a marker near Sydney, Australia.
 * If Google Play services is not installed on the device, the user will be prompted to install
 * it inside the SupportMapFragment. This method will only be triggered once the user has
 * installed Google Play services and returned to the app.
 */
@Override
public void onMapReady(GoogleMap googleMap) {
    mMap = googleMap;
    UiSettings UiSettings = googleMap.getUiSettings();
    UiSettings.setZoomControlsEnabled(true);

    LocationManager service = (LocationManager) getSystemService(LOCATION_SERVICE);
    Criteria criteria = new Criteria();
    String provider = service.getBestProvider(criteria, true);
    //Location myLocation = service.getLastKnownLocation(provider);

    mMap.setMyLocationEnabled(true);




    //double latitude = myLocation.getLatitude();
    //double longitude = myLocation.getLongitude();
    //LatLng startingPosition = new LatLng(latitude, longitude);

    LatLng sydney = new LatLng(-34, 151);
    createMarker();
    //mMap.moveCamera(CameraUpdateFactory.newLatLng(sydney));
}

private void createMarker() {
    Firebase ref = new Firebase("https://shining-fire-3472.firebaseio.com/locations");
    //Query queryRef = ref.orderByChild("latitude");
    ref.addListenerForSingleValueEvent(new ValueEventListener() {
        @Override
        public void onDataChange(DataSnapshot dataSnapshot) {
            for (DataSnapshot userSnapshot : dataSnapshot.getChildren()) {
                markerLocation marker = userSnapshot.getValue(markerLocation.class);
                Double lat = Double.parseDouble(marker.getLatitude());
                Double log = Double.parseDouble(marker.getLongtitude());
                LatLng latLng = new LatLng(lat, log);
                mMap.addMarker(new MarkerOptions().position(latLng));
            }
        }

        @Override
        public void onCancelled(FirebaseError firebaseError) {

        }
    });
}
}

Here is the appbuild gradle:

这是appbuild gradle:

apply plugin: 'com.android.application'

android {
compileSdkVersion 23
buildToolsVersion "23.0.2"

defaultConfig {
    applicationId "com.test.googlemap"
    minSdkVersion 17
    targetSdkVersion 23
    versionCode 1
    versionName "1.0"
    multiDexEnabled true
}
buildTypes {
    release {
        minifyEnabled false
        proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
    }
}
packagingOptions {
    exclude 'META-INF/LICENSE'
    exclude 'META-INF/LICENSE-FIREBASE.txt'
    exclude 'META-INF/NOTICE'
    exclude 'META-INF/services/com.fasterxml.jackson.core.ObjectCodec'
}
dexOptions {
    preDexLibraries = false
    incremental = true;
    javaMaxHeapSize "4g"
}
}

dependencies {
compile fileTree(include: ['*.jar'], dir: 'libs')
testCompile 'junit:junit:4.12'
compile 'com.android.support:appcompat-v7:23.2.0'
compile 'com.google.android.gms:play-services:8.4.0'

compile files('libs/firebase-client-android-2.5.2.jar')

}

I am trying to retrieve marker location objects in order to create custom markers that will show up the Map. The project will sync but whenever I try and build an APK I get this error:

我正在尝试检索标记位置对象,以便创建将显示地图的自定义标记。该项目将同步,但每当我尝试构建APK时,我会收到此错误:

Error:Execution failed for task ':app:dexDebug'.> com.android.ide.common.process.ProcessException: org.gradle.process.internal.ExecException: Process 'command 'C:\Program Files (x86)\Java\jdk1.8.0_60\bin\java.exe'' finished with non-zero exit value 1

错误:任务':app:dexDebug'执行失败。> com.android.ide.common.process.ProcessException:org.gradle.process.internal.ExecException:进程'命令'C:\ Program Files(x86)\ Java \ jdk1.8.0_60 \ bin \ java.exe''以非零退出值1结束

I've tried all of the fixes from other similar questions but none have worked for me.

我尝试过其他类似问题的所有修复,但没有一个对我有用。

Based on this page, they solved this kind of issue by using following this steps.

基于此页面,他们通过使用以下步骤解决了这类问题。

1. Download & unzip the SDK. This should create a folder named Parse-1.xx.x (Parse-1.11.0 in my case)

下载并解压缩SDK。这应该创建一个名为Parse-1.xx.x的文件夹(在我的例子中为Parse-1.11.0)

2. Move the entire folder to /apps/libs (make sure you deleted the previous Parse-*.jar file)

将整个文件夹移动到/ apps / libs(确保删除了以前的Parse - * .jar文件)

3. Build > Rebuild project

构建>重建项目

If you have problem with bolts file you can resolve it by following this steps.

如果螺栓文件有问题,可以按照以下步骤解决。

1. Go to: https://github.com/ParsePlatform/Parse-SDK-Android

请访问:https://github.com/ParsePlatform/Parse-SDK-Android

2. Download the jar file

下载jar文件

3. Store the downloaded jar file in the src/main/libs folder

将下载的jar文件存储在src / main / libs文件夹中

4. Then add the dependency in the build.gradle(module:app) file " compile 'com.parse:parse-android:1.11.0' " -> or whatever is the version number for the jar file.

然后在build.gradle(module:app)文件中添加依赖项“compile”com.parse:parse-android:1.11.0'“ - >或者jar文件的版本号。

5. Sync the gradle file.

同步gradle文件。
