Android - 谷歌地圖實現

我目前正在致力於Android項目，要求我實施谷歌地圖。我已經遵循了一些教程來做到這一點，但仍然有一些錯誤。下面是我的錯誤：Android - 谷歌地圖實現

下面是我的AndroidManifest.xml

     Note that the API key is linked to the encryption key used to sign the APK. 
     You need a different API key for each encryption key, including the release key that is used to 
     sign the APK for publishing. 
     You can define the keys for the debug and release targets in src/debug/ and src/release/.

    <activity

     android:label="@string/title_activity_maps"></activity> 
</application>

下面是我的build.gradle

apply plugin: 'com.android.application' 

android { 
compileSdkVersion 23 
buildToolsVersion "23.0.1" 
useLibrary 'org.apache.http.legacy' 

defaultConfig { 
    applicationId "com.example..." 
    minSdkVersion 15 
    targetSdkVersion 23 
    versionCode 1 
    versionName "1.0" 
} 
buildTypes { 
    release { 
     minifyEnabled false 
     proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro' 
    } 
} 
} 

dependencies { 
compile fileTree(include: ['*.jar'], dir: 'libs') 
testCompile 'junit:junit:4.12' 
compile 'com.google.http-client:google-http-client-android:+' 
compile 'com.google.api-client:google-api-client-android:+' 
compile 'com.google.api-client:google-api-client-gson:+'

compile 'com.android.support:appcompat-v7:23.1.1' 
compile 'com.google.android.gms:play-services:8.3.0' 
}

這裏是我的MapsActivity.java

package com.example...; 

import android.support.v4.app.FragmentActivity; 
import android.os.Bundle; 

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

public class MapsActivity extends FragmentActivity implements OnMapReadyCallback { 

private GoogleMap mMap; 

@Override 
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); 
} 


/** 
* 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; 

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

我已經嘗試過多種方法，但它並沒有爲我工作。希望有人能幫我解決我的問題。

在此先感謝。

添加到您的清單，然後嘗試..

<permission 
    android:name="com.example.yourprojectname.permission.MAPS_RECEIVE" 
    android:protectionLevel="signature" />

替換「com.example.yourprojectname」你的包名。
