Question

当我在OrmLite的项目上使用Proguard时。我收到了错误：

java.lang.RuntimeException: Unable to start activity ComponentInfo{com.package.name/com.package.name.activities.StartActivity}:
java.lang.IllegalStateException: Could not find OpenHelperClass because none of the generic parameters of class class com.package.name.activities.StartActivity extends OrmLiteSqliteOpenHelper.  You should use getHelper(Context, Class) instead.

我已经尝试了Proguard with OrmLite on Android和其他资源的所有推荐，但没有结果

Answer 1

将以下内容放在proguard-project文件和proguard-optimization文件中（如果使用优化）。

 # Your application may contain more items that need to be preserved; 
 # typically classes that are dynamically created using Class.forName: 
 # ormlite uses reflection 
 -keep class com.j256.** { *; }
 -keep class com.j256.**
 -keepclassmembers class com.j256.**
 -keep enum com.j256.**
 -keepclassmembers enum com.j256.**
 -keep interface com.j256.**
 -keepclassmembers interface com.j256.**

-keepclassmembers class * { 
  public <init>(android.content.Context); 
} 

-keepattributes *Annotation*

并为每个模型类：

-keep class com.xyz.components.**
-keepclassmembers class com.xyz.components.** { *; }

我不喜欢最后一部分，但我已经厌倦了寻找更好的解决方案。

Answer 2

我问了同样的问题crash using ORMLite on Android with proguard，答案是添加

-keepattributes Signature

到proguard配置。

Answer 3

您可以使用以下proguard配置来保留OrmLite

使用的所有模型类

-keep @com.j256.ormlite.table.DatabaseTable class * {
    @com.j256.ormlite.field.DatabaseField <fields>;
    @com.j256.ormlite.field.ForeignCollectionField <fields>;
    # Add the ormlite field annotations that your model uses here
    <init>();
}

Answer 4

最新版 OrmLite 5 只是一小部分。

您可能希望添加这些行以隐藏一些新警告：

-dontwarn com.j256.ormlite.android.**
-dontwarn com.j256.ormlite.logger.**
-dontwarn com.j256.ormlite.misc.**
