Question

突然地图停止在我的应用中工作，只是在左下角显示一个带有Google徽标的空白屏幕。

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).

我认为可能的唯一想法是身份验证错误。因为我尝试过不同的网络并且没有遇到麻烦。

问题可能出在build.gradle文件中吗？我想，因为问题在我搞砸了之后就开始了。

这是我的构建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：

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.app" >

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

    android:glEsVersion="0x00020000"
    android:required="true" />

<application
    android:allowBackup="true"
    android:icon="@drawable/ic_launcher"
    android:label="@string/app_name"
    android:theme="@style/AppTheme" >

    ...

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

我多次检查过packageName，sha1指纹和API是否正确。所有这些都是，但我仍然得到一张空地图。

我在那里看到过类似的问题，但没有找到我找到的解决方案。它只是拒绝为我工作。

有什么建议吗？

编辑：我没有尝试过任何工作。但我确实找到了一个似乎有同样问题的人的类似问题：Google Maps Android API Authorization failure - has this service changed in the last few months?

我有完全相同的问题，解决方案根本不明显。检查您是否使用以下命令更改DefaultSSLSocketFactory

HttpsURLConnection.setDefaultSSLSocketFactory(sslContext.getSocketFactory());

删除此行并为所需连接设置套接字工厂使我的地图有效。
