我在android应用程序中使用了realm db我按照文档集成了realm db,如下所示:
build.gradle(项目级别)
dependencies {
classpath 'com.android.tools.build:gradle:2.3.3'
classpath 'com.neenbedankt.gradle.plugins:android-apt:1.4'
classpath "io.realm:realm-gradle-plugin:3.7.0"
// NOTE: Do not place your application dependencies here; they belong
// in the individual module build.gradle files
}
build.gradle(应用级别)
apply plugin: 'com.android.application'
apply plugin: 'io.fabric'
apply plugin: 'com.neenbedankt.android-apt'
apply plugin: 'realm-android'
以下是MyApplication Class中的代码
Realm.init(this);
RealmConfiguration config = new RealmConfiguration.Builder()
.name(Realm.DEFAULT_REALM_NAME)
.schemaVersion(1)
.deleteRealmIfMigrationNeeded()
.build();
Realm.getInstance(config);
Realm.setDefaultConfiguration(config);
模型类
public class MyModel extends RealmObject {
@PrimaryKey
@SerializedName("message")
private String message;
@SerializedName("session_expired")
private Integer sessionExpired;
@SerializedName("domain_name")
private String domainName;
public String getDomainName() {
return domainName;
}
public void setDomainName(String domainName) {
this.domainName = domainName;
}
public String getMessage() {
return message;
}
public void setMessage(String message) {
this.message = message;
}
public Integer getSessionExpired() {
return sessionExpired;
}
public void setSessionExpired(Integer sessionExpired) {
this.sessionExpired = sessionExpired;
}
}
现在,就调试版本而言,app正在按预期运行而不会发生任何崩溃。 但是当我生成发布版本时,应用程序会崩溃
io.realm.exceptions.RealmException:' MyModel'目前还不存在 架构。
请看一下上面的代码,请帮我解决这个问题。在此先感谢。
注意:我正在访问一个领域对象
Realm realm = Realm.getDefaultInstance();
以下是stacktrace
E/AndroidRuntime: FATAL EXCEPTION: main
io.realm.exceptions.RealmException: 'MyModel' doesn't exist in current schema.

以下是我访问MyModel类的方法
final RealmQuery<MyModel> query = mRealm.where(MyModel.class).equalTo("message", "Success");
RealmResults<MyModel> result = query.findAll();
mRealm.executeTransaction(new Realm.Transaction() {
@Override
public void execute(Realm realm) {
MyModel myModel = query.findFirst();
if (myModel != null) {
myModel.setDomainName(strDomain);
}
}
});

您是否尝试过更新到最新版本? 定期检查the Realm changelog是否有错误修正是个好主意。
我遇到了类似的问题,并且更新到Realm v3.7.2解决了它。在更改日志中,您可以找到:
当前架构中不存在“'xxx'崩溃。”启用ProGuard时(#5211)。
