android - NoClassDefFoundError FirebaseOptions，安卓？

Question

我在设备上运行我的应用程序时遇到此异常。

java.lang.NoClassDefFoundError: com.google.firebase.FirebaseOptions

我什至没有使用 Firebase API，它仍然以某种方式获取引用。

这是我的应用程序 gradle 文件

apply plugin: 'com.android.application'

android {
compileSdkVersion 23
buildToolsVersion "24.0.1"

defaultConfig {
    applicationId "com.supe.supermax"
    minSdkVersion 16
    targetSdkVersion 23
    versionCode 1
    versionName "1.0"
    multiDexEnabled true
}

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

dependencies {
compile fileTree(include: ['*.jar'], dir: 'libs')
testCompile 'junit:junit:4.12'
compile 'com.android.support:appcompat-v7:23.4.0'
compile 'com.android.support:design:23.4.0'
compile 'com.android.support:support-v4:23.4.0'
compile 'com.github.lzyzsd:circleprogress:1.1.0@aar'
compile 'com.nostra13.universalimageloader:universal-image-loader:1.9.5'
compile 'com.google.android.gms:play-services:9.2.1'
compile 'com.github.gcacace:signature-pad:1.1.0'
compile project(':ViewPagerIndicator')
}

我该如何解决？

Answer 1

NoClassDefFoundError

Thrown if the Java Virtual Machine or a ClassLoader instance tries to load in the definition of a class (as part of a normal method call or as part of creating a new instance using the new expression) and no definition of the class could be found.

您应该使用降级 版本 9.0.0 而不是 9.2.1

compile 'com.google.android.gms:play-services:9.0.0'

并添加multidex

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

希望对您有所帮助。
