Question

我最近更新到Android的新版本。自更新以来，我一直有问题让我的地图出现。我只是多次重新生成API密钥而无济于事

这是我的清单：

         The API key for Google Maps-based APIs is defined as a string resource.

         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/.

    <meta-data

    <activity

        android:exported="true" />

    </activity>
</application>

这是我的gradle文件：

apply plugin: 'com.android.application'

android {
compileSdkVersion 25
buildToolsVersion "25.0.2"
defaultConfig {
    applicationId "com.morticia.android.pop"
    minSdkVersion 19
    targetSdkVersion 25
    versionCode 1
    versionName "1.0"
    testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
}

ext{
    supportLibVersion = '25.3.0'
}
buildTypes {
    release {
        minifyEnabled false
        proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
    }
}
}

dependencies {
compile fileTree(include: ['*.jar'], dir: 'libs')
androidTestCompile('com.android.support.test.espresso:espresso-core:2.2.2', {
    exclude group: 'com.android.support', module: 'support-annotations'

}
apply plugin: 'com.google.gms.google-services'

configurations.all {
resolutionStrategy.eachDependency { DependencyResolveDetails details ->
    def requested = details.requested
    if (requested.group == 'com.android.support') {
        if (!requested.name.startsWith("multidex")) {
            details.useVersion '25.3.0'
        }
    }
}
}

以下是onCreate（）的活动：

public class MapsActivity extends FragmentActivity implements OnMapReadyCallback,
    GoogleApiClient.ConnectionCallbacks,
    GoogleApiClient.OnConnectionFailedListener, LocationListener, OnClickListener{
public static final int MY_PERMISSIONS_REQUEST_LOCATION = 99;
//    CircleSize circSize;

LocationRequest mLocationRequest;
Location mLastLocation;
Marker mCurrLocationMarker;
private FirebaseAuth firebaseAuth;
private FirebaseUser user;

private GoogleMap mMap;
private GoogleApiClient mGoogleApiClient;
private PopCityCollection cities;
CityReferrenceDAO cityRef;

private static final String TAG = "MapsActivity";


@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_maps);
    SupportMapFragment mapFragment = (SupportMapFragment) getSupportFragmentManager()
            .findFragmentById(R.id.map_activity);
    mapFragment.getMapAsync(this);
    firebaseAuth = FirebaseAuth.getInstance();

    if(firebaseAuth.getCurrentUser() == null){
        finish();
        startActivity(new Intent(this, LoginActivity.class));
    }
    SlidingUpPanelLayout spl = (SlidingUpPanelLayout) findViewById(R.id.sliding_layout);

    ViewPager viewPager = (ViewPager) findViewById(R.id.viewpager);
    FriendsActivity friends = new FriendsActivity();
    viewPager.setAdapter(new FriendFragmentPagerAdapter(getSupportFragmentManager(), friends));
    TabLayout tabLayout = (TabLayout) findViewById(R.id.sliding_tabs);
    tabLayout.setupWithViewPager(viewPager);

    //check for pops method needs to be added (include pop just made)



}

<强>解决

这个问题不是由于空白地图造成的，而是相机只是放大了海洋。我的风格JSON的水彩与正常水平不同。此问题是在更新Android后导致的，默认情况下未启用“位置”。解决方案是在设备的设置上手动启用设备上的位置，以便摄像机可以根据位置进行编程调整。

谢谢！
