通过USB将我的应用程序安装到手机上时，连接到我的Firebase数据库工作正常。但是当我通过Play商店安装它时，我从Firebase获得有关我的ArrayList具有“泛型类型参数”的问题。查看下面logcat错误消息的第一行：
09-14 15:59:55.715 4843-4843/? E/UncaughtException: com.google.firebase.database.f: Class java.util.ArrayList has generic type parameters, please use GenericTypeIndicator instead

有什么想法？ Google Play版本前几天工作正常，现在发生了！无法在线找到任何解决方案......
更新
我将以下代码添加到我的proguard-rules.pro文件中：
-keepattributes Signature
-keepclassmembers class com.test.finalapp.Models.** {
*;
}
-keep class com.test.finalapp.CoOpStatusHolder { *; }
数据库中的东西运行正常，但现在我遇到了错误：java.lang.RuntimeException：java.lang.NoSuchMethodException：[class android.view.View]
该错误位于较大的logcat错误的顶部：

CoOpStatusHolder是我的FirebaseUI RecyclerView Viewholder。我让Viewholder成为一个内部类。我把它公之于静，它在proguard-rules.pro文件中，所以我仍然不确定问题是什么......
public static class CoOpStatusHolder extends RecyclerView.ViewHolder {
View mView;
public CoOpStatusHolder(View itemView) {
super(itemView);
mView = itemView;
}
public void setName(String name) {
TextView nameOfParentToChoose = (TextView) mView.findViewById(R.id.
textView_of_parent_name_in_co_op_status);
nameOfParentToChoose.setText(name);
}
public void setFacebookImage(String facebookID) {
ProfilePictureView parentFacebookPhoto = (ProfilePictureView) mView.findViewById(R.id.
imageview_of_parent_in_co_op_status);
parentFacebookPhoto.setProfileId(facebookID);
}
public void setHours(Float numofHours) {
TextView numOfHoursForParent = (TextView) mView.findViewById(R.id.
textView_num_of_hours_in_co_op_other_parent_status);
numOfHoursForParent.setText(Float.toString(numofHours));
}
}
