Question

我的应用程序崩溃但没有出现任何错误。我只有一周的时间来启动我的应用程序，但此时我无法追踪错误的位置。这是我的logcat。

    To hide this warning and ensure your app does not break, you need to add the following code to your app before calling any other Cloud Firestore methods:

    FirebaseFirestore firestore = FirebaseFirestore.getInstance();
    FirebaseFirestoreSettings settings = new FirebaseFirestoreSettings.Builder()
        .setTimestampsInSnapshotsEnabled(true)
        .build();
    firestore.setFirestoreSettings(settings);

    With this change, timestamps stored in Cloud Firestore will be read back as com.google.firebase.Timestamp objects instead of as system java.util.Date objects. So you will also need to update code expecting a java.util.Date to instead expect a Timestamp. For example:

    // Old:
    java.util.Date date = snapshot.getDate("created_at");
    // New:
    Timestamp timestamp = snapshot.getTimestamp("created_at");
    java.util.Date date = timestamp.toDate();

    Please audit all existing usages of java.util.Date when you enable the new behavior. In a future release, the behavior will be changed to the new behavior, so if you do not follow these steps, YOUR APP MAY BREAK.

我在日志中遇到了类似的问题：

W/Firestore: (0.6.6-dev) [Firestore]: The behavior for java.util.Date objects stored in Firestore is going to change AND YOUR APP MAY BREAK.
         To hide this warning and ensure your app does not break, you need to add the following code to your app before calling any other Cloud Firestore methods:

         FirebaseFirestore firestore = FirebaseFirestore.getInstance();
         FirebaseFirestoreSettings settings = new FirebaseFirestoreSettings.Builder()
             .setTimestampsInSnapshotsEnabled(true)
             .build();
         firestore.setFirestoreSettings(settings);

         With this change, timestamps stored in Cloud Firestore will be read back as com.google.firebase.Timestamp objects instead of as system java.util.Date objects. So you will also need to update code expecting a java.util.Date to instead expect a Timestamp. For example:

         // Old:
         java.util.Date date = snapshot.getDate("created_at");
         // New:

         java.util.Date date = timestamp.toDate();

         Please audit all existing usages of java.util.Date when you enable the new behavior. In a future release, the behavior will be changed to the new behavior, so if you do not follow these steps, YOUR APP MAY BREAK.

这听起来很奇怪，因为它建议用Timestamp替换Date数据类型，但我目前在我的数据库模型中没有任何Date（甚至Timestamp）数据类型。

我按照建议解决了它： setTimestampsInSnapshotsEnabled（true）。看起来不再支持日期类型。

似乎应用程序在本机代码中崩溃了：

05-06 16:12:50.323 7063-7063/com.cofoz.cofoz D/AndroidRuntime: Shutting down VM
05-06 16:12:50.402 7063-7127/com.cofoz.cofoz W/linker: /data/app/com.google.android.gms-1/lib/arm/libconscrypt_gmscore_jni.so: unused DT entry: type 0xf arg 0x194

在Android Studio中打开logcat时，切换过滤器“仅显示所选应用程序”以显示所有日志行。它可能会告诉你究竟崩溃了什么。通常，使用本机代码时，会使用不兼容的库，或者库仅随ARMv7a一起提供，但您尝试在模拟器上运行应用程序（通常是X86）。

希望它有所帮助。
