android - 不幸的是，应用程序在启动谷歌地图 Activity 时已停止

Question

我正在尝试使用 Google 应用程序 Activity 创建应用程序。我刚刚按照使用 Google map Activity 创建 Google map 应用程序的步骤进行操作，没有添加任何额外的代码。应用程序在启动时崩溃。我在下面给出了我的 list 文件、builde.gradle(app) 和 logcat。 这是我的 list 文件

    <?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.example.ranjit.getlocation">
    <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
    <uses-permission android:name="android.permission.INTERNET" />
    <uses-permission android:name="com.google.android.providers.gsf.permission.READ_GSERVICES" />

    <uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION"/>
    <uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />


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


        <meta-data
            android:name="com.google.android.geo.API_KEY"
            android:value="AIzaSyDd-cGnR0SwDXXDRQPqnTDpBTQ" />

        <activity
            android:name=".MapsActivity"
            android:label="@string/title_activity_maps">
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
    </application>

</manifest>

下面是build.gradle(app)文件

    apply plugin: 'com.android.application'

android {
    compileSdkVersion 25
    buildToolsVersion "25.0.2"
    defaultConfig {
        applicationId "com.example.ranjit.getlocation"
        minSdkVersion 19
        targetSdkVersion 25
        versionCode 1
        versionName "1.0"
        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
        multiDexEnabled true

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

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    androidTestCompile('com.android.support.test.espresso:espresso-core:2.2.2', {
        exclude group: 'com.android.support', module: 'support-annotations'
    })
    compile 'com.android.support:appcompat-v7:25.1.0'
    compile 'com.android.support:multidex:1.0.0'
    compile 'com.google.android.gms:play-services:10.0.1'
    testCompile 'junit:junit:4.12'
}

应用程序的logcat如下

Answer 1

您必须在您的应用程序中包含 multiDex。在您的 list 中，您尚未包含MulitiDexApplication。

ClassNotFoundException: Didn't find class "com.google.firebase.provider.FirebaseInitProvider" on path: DexPathList

将其添加到您的依赖项中。

  compile 'com.android.support:multidex:1.0.1'

在 Gradle 中添加 multiDexEnabled true。

android {
    defaultConfig {
        ...
        minSdkVersion 21 
        targetSdkVersion 26
        multiDexEnabled true    // add this line
    }
    ...
}

在您的 list 中添加 multiDex 应用程序类。

<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.example.myapp">
    <application
            android:name="android.support.multidex.MultiDexApplication" >
        ...
    </application>
</manifest>

避免包含完整的播放服务(编译'com.google.android.gms:play-services:10.0.1')库。相反，使用您需要的特定库。

包含 map 的依赖项。

com.google.android.gms:play-services-maps:11.0.4
