I'm facing this error every single week at least 4 times. It usually happens when I switch building my app from Phone to Emulator. And usually I have to clean project and invalidate cache/restart entire studio 4-10 times in a row in order to remove this error. Is there any normal way to fix this? I think this is clearly some Android Studio bug which is happening randomly and it is starting to slow me in development because I cant build my app for 30-40 minutes straight.

Sometimes I have to uninstall app from phone or emulator or completely wipe out emulator in order to fix this.

CodePudding user response：

This error usually occurs when there exists a file with a same name. Do you have any signed apk in your releases folder? If it's there, delete it and it may stop colliding. If it persists, try Clean Project and generate a signed apk.
