我正在尝试将DBFlow合并到Android应用程序中。我已经按照文档here进行了操作,但未能使该库工作。
以下是我写的相关文件:
build.gradle
def dbflow_version = "4.0.0-beta3"
def sqlcipher_version = "3.3.1"
dependencies {
// ...
// DBFlow
annotationProcessor "com.github.Raizlabs.DBFlow:dbflow-processor:${dbflow_version}"
compile "com.github.Raizlabs.DBFlow:dbflow-core:${dbflow_version}"
compile "com.github.Raizlabs.DBFlow:dbflow:${dbflow_version}"
compile "com.github.Raizlabs.DBFlow:dbflow-sqlcipher:${dbflow_version}"
compile "net.zetetic:android-database-sqlcipher:${sqlcipher_version}@aar"
}
proguard-rules.pro
# sqlCipher
-keep class net.sqlcipher.** { *; }
-dontwarn net.sqlcipher.**
在我的Application
课程中,我在onCreate()
回调期间运行了以下内容
private void initFlowDb() {
DatabaseConfig.OpenHelperCreator openHelperCreator = SqlCipherHelperImpl::new;
DatabaseConfig databaseConfig = new DatabaseConfig.Builder(AppDatabase.class)
.openHelper(openHelperCreator)
.build();
FlowConfig flowConfig = new FlowConfig.Builder(this)
.openDatabasesOnInit(true)
.addDatabaseConfig(databaseConfig)
.build();
FlowManager.init(flowConfig);
}
以下是各自的数据库类
AppDatabase.java
@Database(name = AppDatabase.NAME, version = AppDatabase.VERSION)
public class AppDatabase {
public static final String NAME = "AppDatabase";
public static final int VERSION = 1;
}
一个死的简单模型类,如下所示
CreditCardDbModel.java
@Table(database = AppDatabase.class)
public class CreditCardDbModel extends BaseModel {
@Column
private String cardNumber;
@Column
private int expiryMonth;
@Column
private int expiryYear;
@Column
private int cvv;
// ...
}
以下代码会引发错误
FlowManager.getDatabase(AppDatabase.class)
.beginTransactionAsync(databaseWrapper -> {
creditCardDbModel.save();
})
.success(transaction -> {
Timber.tag(TAG).d("Done saving model");
})
.error((transaction, error) -> {
Timber.tag(TAG).e("Error saving model");
Timber.tag(TAG).e(error);
})
.build()
.execute();
这会触发以下异常
E com.raizlabs.android.dbflow.structure.InvalidDBConfiguration: Database: com.rperryng.android.db.AppDatabase is not a registered Database. Did you forget the @Database annotation?
E at com.raizlabs.android.dbflow.config.FlowManager.getDatabase(FlowManager.java:115)
E at com.rperryng.android.ui.main.other.AddPaymentActivity.onSaveCardClicked(AddPaymentActivity.java:107)
如果我尝试在事务之外使用creditCardDbModel.save()
(即同步保存),我会收到类似的错误:
E com.raizlabs.android.dbflow.structure.InvalidDBConfiguration: Model object: com.rperryng.android.db.CreditCardDbModel is not registered with a Database. Did you forget an annotation?
SQLCipher
集成,即将initFlowDb()
更改为FlowManager.init(new FlowConfig.Builder(this).openDatabasesOnInit(true).build());
-keep class * extends com.raizlabs.android.dbflow.config.DatabaseHolder { ; }
-keep class com.raizlabs.android.dbflow.config.GeneratedDatabaseHolder
-keep class * extends com.raizlabs.android.dbflow.config.BaseDatabaseDefinition { *; }
-keep class com.rperryng.android.db.* { *; }
然而,我仍然遇到了同样的错误 - 数据库未注册。我真的看不出我做错了什么。我已经回去查看了几次文档,以确保所有内容都设置正确,但我仍然没有遇到此错误。任何帮助都将深表感谢!

在家属中将annotationProcessor
更改为apt
。
