Question

目前我的应用minSdkVersion 15。一切都很好。根据我要添加到我的应用中的内容，我需要multidex或minSdkVersion 21或更高版本。无论哪种方式我尝试，我的应用程序崩溃给我这个错误。

我没有添加任何依赖项就得到了。我所做的就是将minSdkVersion更改为21.我通过Google找到的所有内容都指向需要使用multidex。但我实际上还没有添加任何依赖性来实际需要multidex。当我添加multidex时，我得到相同的日志。

这是我的Gradle

apply plugin: 'com.android.application'

    android {
        compileSdkVersion 24
        buildToolsVersion "23.0.1"

    defaultConfig {
        applicationId "com.JEB.trailmaps"
        minSdkVersion 15
        targetSdkVersion 24
        versionCode 533
        versionName "5.3.3"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}
    repositories {
        mavenCentral()
    }

    dependencies {
        compile fileTree(dir: 'libs', include: ['*.jar'])
        compile 'com.mapbox.mapboxsdk:mapbox-android-sdk:5.5.1'
        compile 'com.android.support:support-v4:25.0.0'
        compile 'com.android.support:appcompat-v7:25.0.0'
        compile 'com.android.support:design:25.0.0'
        compile 'com.android.support:recyclerview-v7:25.0.0'
        compile 'com.android.support:cardview-v7:25.0.0'
        compile 'com.google.firebase:firebase-database:9.4.0'
        compile 'com.firebaseui:firebase-ui-database:0.4.0'
        compile "com.google.android.gms:play-services-places:9.4.0"
        compile 'com.google.android.gms:play-services-ads:9.4.0'
    }
apply plugin: 'com.google.gms.google-services'

Answer 1

我注意到了一些事情：

您的依赖关系会在25.0.0

compileSdkVersion and
targetSdkVersion is 24

假设您已将规则添加到根级build.gradle文件中，以包含google-services插件和Google's Maven repository

buildscript {
    // ...
    dependencies {
        // ...
        classpath 'com.google.gms:google-services:3.2.0' // google-services plugin
    }
}

allprojects {
    // ...
    repositories {
        // ...
        maven {
            url "https://maven.google.com" // Google's Maven repository
        }
    }
}

如果您使用build:gradle:3.0 or higher please use implementation代替compile
如果您有firebase dependencies，请务必将其版本更新为google services的{{3}}
推荐：下载最新的Google支持存储库（如果您使用的是firebase和Google服务，则至少为26.0.0或更高版本） - 您可以在Tools -> Android -> SDK Manager -> SDK Tools中找到它
无法解决com.firebaseui:firebase-ui-database:0.4.0阅读更多match version

因此，您的最终Gradle文件应如下所示：

apply plugin: 'com.android.application'

android {
    compileSdkVersion 26
    buildToolsVersion "26.0.3"

    defaultConfig {
        applicationId "com.JEB.trailmaps"
        minSdkVersion 15
        targetSdkVersion 26
        versionCode 533
        versionName "5.3.3"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
    repositories {
        mavenCentral()
        jCenter()
    }
}
dependencies {
    implementation fileTree(dir: 'libs', include: ['*.jar'])
    implementation 'com.mapbox.mapboxsdk:mapbox-android-sdk:5.5.1'
    implementation 'com.android.support:support-v4:26.1.0'
    implementation 'com.android.support:appcompat-v7:26.1.0'
    implementation 'com.android.support:design:26.1.0'
    implementation 'com.android.support:recyclerview-v7:26.1.0'
    implementation 'com.android.support:cardview-v7:26.1.0'
    implementation 'com.google.firebase:firebase-database:12.0.0'
    implementation 'com.firebaseui:firebase-ui-database:0.4.0'
    implementation 'com.google.android.gms:play-services-places:12.0.0'
    implementation 'com.google.android.gms:play-services-ads:12.0.0'
    implementation 'com.android.support:multidex:1.0.0'
}
apply plugin: 'com.google.gms.google-services'

minSdkVersion 21崩溃应用程序。 20及以下工作正常
