我刚刚将React Native升级到0.59.5版本,并且在调试模式下一切正常。当我尝试组装发行版(./gradlew assembleRelease)时,问题就来了。编译器给我错误:
任务':app:mergeDexRelease'的执行失败。
com.android.build.api.transform.TransformException:java.lang.RuntimeException:java.lang.RuntimeException:java.lang.OutOfMemoryError
我做了一些重新研究,可能由于多种原因而发生:
不良图像处理
内存泄漏
大ScrollView和Flatlist处理不当
...
我试图优化我的代码,它在调试模式下运行的非常顺畅,并且似乎运行良好。厌倦了尝试优化代码,我注释了代码的所有大部分,但仍然收到此错误。
我还尝试指定Andorid来升级堆内存空间,并在Android Manifest上启用大堆,但这也不起作用。
有人知道为什么会这样吗?预先感谢。
这是我的android / app / build.gradle文件:
