没有更新的 apk 文件，在 android studio 上运行的项目

Question

How to clean a project in Android Studio? I have changed the project from Eclipse and my apk file is not updating, it contains the old apk file from Eclipse. I did rebuild project, doesn't help. Also checked Out folder, no apk for this project is there. Also I changed my project name once while it was in Eclipse. Now the Out folder still contains the old projectname.apk file. Would really appreciate your help.

Answer 1

当您认为 Android Studio（或 Intellij IDEA）没有接受外部所做的更改时，有时File -> Invalidate Caches...会有所帮助。

Answer 2

In my own case, deleting the existing/old apk in the output folder helped to resolve this issue. If you run into this problem, it might be worth trying the following sequence of steps:

• I opened my file manager and deleted the existing apk file.
• I opened Android studio and clicked on Build APK(s).

Answer 3

I had this problem before and this way helped me. You can run this at the root of your project

react-native bundle --platform android --dev false --entry-file index.js --bundle-output android/app/src/main/assets/index.android.bundle --assets-dest android/app/src/main/res/

Then cd to android and run this

./gradlew assembleDebug
