无法找到类com.google.firebase.provider.FirebaseInitProvider低于API级别21

我收到错误API等级19（奇巧）和它的作品在API 23 &以上罚款。我还在Gradle文件中启用了MultiDex和multidex的依赖关系。但它不起作用。请建议我一个solution.Code是在这里：无法找到类com.google.firebase.provider.FirebaseInitProvider低于API级别21

这里我gradle这个文件： -

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' 

}

'compileSdkVersion 25，targetSdkVersion 25，V7：25.2.0，而不是V7的：24.2.1'。然后清理重建和运行 –

，如果你面临同样的问题告诉我 –

同样的错误没有什么变化 –

你尝试在你的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：

dependencies { 
    compile 'com.android.support:multidex:1.0.1' 
}
