android-无法在API级别21以下找到类com.google.firebase.provider.FirebaseInitProvider

概述我在API级别19(Kitkat)中遇到错误,并且在API23&以上.我还在gradle文件和multidex依赖项中启用了MultiDex.但它不起作用.请给我建议一个解决方案.代码在这里：java.lang.RuntimeException:Unabletogetprovidercom.google.firebase.provider.FirebaseInitProvide

我在API级别19(Kitkat)中遇到错误,并且在API 23&以上.我还在gradle文件和multIDex依赖项中启用了MultIDex.但它不起作用.请给我建议一个解决方案.代码在这里：

这是我的gradle文件：-

apply plugin: 'com.androID.application'androID {    compileSdkVersion 24    buildToolsversion "25.0.2"    defaultConfig {        applicationID "com.trackawesome"        minSdkVersion 15        targetSdkVersion 24        versionCode 1        versionname "1.0"        multIDexEnabled true        testInstrumentationRunner "androID.support.test.runner.AndroIDJUnitRunner"    }    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-v7:24.2.1'    compile 'com.Google.androID.gms:play-services:10.2.1'    compile 'com.squareup.retrofit:retrofit:1.9.0'    compile 'com.androID.support:recyclervIEw-v7:24.2.1'    compile 'com.squareup.picasso:picasso:2.5.2'    compile 'com.androID.support:cardvIEw-v7:24.2.1'    compile 'com.androID.support:multIDex:1.0.1'    testCompile 'junit:junit:4.12'}

解决方法:

您是否尝试过在AndroIDManifest.xml文件中添加MultIDex应用程序类？

<?xml version="1.0" enCoding="utf-8"?><manifest xmlns:androID="http://schemas.androID.com/apk/res/androID"    package="com.example.myapp">    <application            androID:name="androID.support.multIDex.MultIDexApplication" >        ...    </application></manifest>

添加以下依赖项：

dependencIEs {  compile 'com.androID.support:multIDex:1.0.1'}
