Question

最后更新Crashlytics with Fabric本机应用程序崩溃了一些时间（使用Android 7.1.1在nexus 6上测试）

我在Google Play控制台中看到的是这个。

当然是funler.com.funler.FunlerApplication.onCreate (FunlerApplication.java:27)

我有

Fabric.with(this, new Crashlytics());

我发现了与MultiDex.install(this)相关的问题，但我的代码中没有。还看到了与dexOptions相关的内容，不知道该怎么做。

最大的问题是我无法按需要重现它，在设备中尝试它会发生~1次20次。

apply plugin: 'com.android.application'
apply plugin: 'io.fabric'

ext {
        versionSdk = 25

        major = 3
        minor = 2
        patch = 5
}

def generateVersionCode(){

        return ext.versionSdk * 1000000 +
                        ext.major * 10000 +
                        ext.minor * 100 +

Answer 1

它可能是由代码缩小（混淆）引起的。如果您正在使用proguard（并且在发布版本上发生了问题），您可能想要查看您使用的某个库是否需要手动添加一些proguard规则。

祝你好运。

更新到Fabric Crashlytics后，有时本机会崩溃与java.lang.NoClassDefFoundError
