谷歌地图突然不能用了 [英] Google maps suddenly not working

问题描述

突然地图在我的应用程序中停止工作，只显示一个空白屏幕，左下角带有谷歌徽标.

All of a sudden maps stopped working in my app and just shows a blank screen with the google logo in the bottom left corner.

我得到的错误是:

I/Google Maps Android API﹕ Google Play services package version: 4452038
I/ActivityManager﹕ Start proc com.google.android.gms.maps for service com.google.android.gms/.maps.auth.ApiTokenService: 
I/Google Maps Android API﹕ Google Play services client version: 4452000
I/Google Maps Android API﹕ Failed to contact Google servers. Another attempt will be made when connectivity is established.
E/Google Maps Android API﹕ Failed to load map. Error contacting Google servers. This is probably an authentication issue (but could be due to network errors).

我认为唯一可能是身份验证错误.因为我在不同的网络上尝试过并且没有遇到任何问题.

The only think I believe is possible is an authentication error. Since I've tried on different networks and have not troubles there.

问题可能出在 build.gradle 文件上吗?因为问题是在我在那里搞砸之后才开始的，我想.

Could the problem be with the build.gradle file? Because the problems started after I messed around there, i think.

这是我的构建gradle:

This is my build gradle:

apply plugin: 'android'

android {
compileSdkVersion 19
buildToolsVersion "19.0.3"

def versionPropsFile = file('version.properties')

if (versionPropsFile.canRead()) {
    def Properties versionProps = new Properties()

    versionProps.load(new FileInputStream(versionPropsFile))

    def value = 0

    def runTasks = gradle.startParameter.taskNames
    if ('assemble' in runTasks || 'assembleRelease' in runTasks || 'aR' in runTasks) {
        value = 1;
    }

    def versionMajor = 1
    def versionMinor = 3
    def versionPatch = versionProps['VERSION_PATCH'].toInteger() + value
    def versionBuild = versionProps['VERSION_BUILD'].toInteger() + 1
    def version_Code = versionProps['VERSION_CODE'].toInteger() + value

    versionProps['VERSION_PATCH'] = versionPatch.toString()
    versionProps['VERSION_BUILD'] = versionBuild.toString()
    versionProps['VERSION_CODE'] = version_Code.toString()

    versionProps.store(versionPropsFile.newWriter(), null)

    defaultConfig {
        versionCode version_Code
        versionName "${versionMajor}.${versionMinor}.${versionPatch} (${versionBuild})"
        minSdkVersion 14
        targetSdkVersion 19
    }
} else {
    throw new GradleException("Could not read version.properties!")
}

signingConfigs {
    debug {
        storeFile file("xxx.keystore")
        storePassword "xxxx"
        keyAlias "debug"
        keyPassword "xxxx"
    }
    releaseKey {
        storeFile file("xxx.keystore")
        storePassword "xxxx"
        keyAlias "release"
        keyPassword "xxxx"
    }
}

buildTypes {
    debug {
        debuggable true
        packageNameSuffix ".debug"
        proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.txt'
        signingConfig signingConfigs.debug
    }

    release {
        proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.txt'
        signingConfig signingConfigs.releaseKey
    }
}

lintOptions {
    abortOnError false
}
}

dependencies {
    compile project(':nineOldAndroids')
    compile project(':expListViewLib')
    compile project(':datetimepickerlibrary')
    compile project(':volley')
    compile 'com.android.support:support-v4:+'
    compile 'com.google.android.gms:play-services:+'
    compile files('libs/aws-android-sdk-1.7.1.1.jar')
    compile files('libs/disklrucache-2.0.1.jar')
}

清单如下所示:

    <meta-data android:name="com.google.android.maps.v2.API_KEY" android:value="@string/config_com.google.android.maps.v2.api_key" />
</application>
</manifest>

我已经多次检查 packageName、sha1 指纹和 API 是否正确.他们都是，但我仍然得到一张空地图.

I have checked multiple times that packageName, sha1 fingerprint and API is correct. All of them are, but I still get an empty map.

我在那里看到过类似的问题，但我没有找到任何解决方案.它只是拒绝为我工作.

I've seen similar questions out there but none of the solutions I found. It just refuses to work for me.

有什么建议吗?

我尝试过的任何东西都不起作用.但我确实发现了一个类似的问题，某人似乎有同样的问题:Google Maps Android API 授权失败 - 此服务在过去几个月内是否发生了变化?

Nothing that I have tried works. But I did find a similar question with someone who seems to have the same problem: Google Maps Android API Authorization failure - has this service changed in the last few months?

推荐答案

我遇到了完全相同的问题，而且解决方案根本不明显.检查您是否没有更改 DefaultSSLSocketFactory :

I had exactly the same problem and the solution was not obvious at all. Check if you are not changing DefaultSSLSocketFactory with:

HttpsURLConnection.setDefaultSSLSocketFactory(sslContext.getSocketFactory());

删除此行并仅为所需连接设置套接字工厂使我的地图工作.

Removing this line and setting socket factory just for the required connection made my maps work.
