我们为我们的应用程序使用Realm.我们的应用已经发布测试版.现在我想在我们的一个领域对象中添加一个字段.所以我写了RealmMigration,我也写了一个.这里的问题是如何将此Realm迁移应用到我的应用程序.我使用Realm.getInstance()在我想要的时候获取领域实例.请记住,Realm.getInstance()每次都在整个应用程序中使用,我想访问Realm数据库.
那么,我有点询问如何应用这种迁移？任何线索都可能有所帮助.谢谢.
我的RealmMigration如下.
public class RealmMigrationClass implements RealmMigration {
@Override
public void migrate(DynamicRealm realm, long oldVersion, long newVersion) {
if(oldVersion == 0) {
RealmSchema sessionSchema = realm.getSchema();
if(oldVersion == 0) {
RealmObjectSchema sessionObjSchema = sessionSchema.get("Session");
sessionObjSchema.addField("isSessionRecordingUploading", boolean.class, FieldAttribute.REQUIRED)
.transform(new RealmObjectSchema.Function() {
@Override
public void apply(DynamicRealmObject obj) {
obj.set("isSessionRecordingUploading", false);
}
});
sessionObjSchema.setNullable("isSessionRecordingUploading",false);
oldVersion++;
}
}
}
}
public class Session extends RealmObject {
@PrimaryKey
private String id;
@Required
private Date date;
private double latitude;
private double longitude;
private String location; …我最近更新了我的kotlin和kotlin扩展插件,在构建时我收到以下错误.我尝试使用gradle清理构建或同步项目,但没有任何作用

更新：
adb shell am start -W -a android.intent.action.VIEW -d " http://www.clinicloud.com/xyz " com.clinicloud.app
使用 adb 测试会打开应用程序，但仅使用浏览器测试不会打开应用程序。
我正在使用Kotlin Fuel框架来进行REST API调用.实际上,只要api有http uri,一切都运行良好.但是当uris作为HTTP安装SSL证书时,我无法从亚马逊服务器下载图像.我收到以下错误并阻止了UI.有没有人知道如何解决这个问题？
