如何解决我的应用发布版本上的错误和崩溃
我的应用发行版存在很大的问题。 （https://play.google.com/store/apps/details?id=com.conta.ftof 请尝试下载它以帮助我） 在调试版本中，一切正常，但在发布版本中，只要我通过电话号码对Firebase进行身份验证或仅进行身份验证，然后单击“回收者视图”按钮，应用程序就会崩溃...我最近添加了sha键-1和sha-256到firebase项目，我添加了新的json文件，因为身份验证不起作用，现在身份验证可以正常工作，但是正如我已经说过的，只要您通过身份验证，该应用程序就会崩溃。我不知道是不是Google广告的问题，这是我在1星期前在contactsactivity中添加的。奇怪的是调试版本可以正常运行...我留给您代码了...

解决方法
如果您是初学者，那么我建议您在build.gradle中禁用minifyEnabled。基本上proguard会混淆代码，并且您可能不会在proguard规则中转义模型文件
android {
...
buildTypes {
release {
minifyEnabled false // disable proguard
...
}
}
}
[UPDATE]：这是您可以在progaurd中转义文件的方式
在您的proguard-android-optimize.txt文件中执行以下操作
如果所有模型都在同一文件夹中，则：
-keep public class com.myapp.models.** {
public protected private *;
}
否则，您可以使用以下方式跳过文件：
-keep public class com.myapp.models.MyModel {
public protected private *;
}
