清除 Android Realm 默认数据库

Question

如何清除 android 中的默认 Realm 数据库？我尝试了以下代码，但无法解析 deleteRealmFile 方法。

方法一:

try {
   Realm.deleteRealmFile(context);
  //Realm file has been deleted.

} catch (Exception ex){
   ex.printStackTrace();
  //No Realm file to remove.
}

我尝试使用配置删除。

方法二:

try {
     Realm.deleteRealm(realm.getConfiguration());
     //Realm file has been deleted.
} catch (Exception ex){
     ex.printStackTrace();
     //No Realm file to remove.
}

但是给出了错误:

java.lang.IllegalStateException: It's not allowed to delete the file associated with an open Realm. Remember to close() all the instances of the Realm before deleting its file.

Answer 1

在 Realm.deleteRealm(realm.getConfiguration()); 之前添加 realm.close() 如下所示，它就像一个魅力

try {
      realm.close()
      Realm.deleteRealm(realm.getConfiguration());
                //Realm file has been deleted.
} catch (Exception ex){
                ex.printStackTrace();
                //No Realm file to remove.
}
