"Unfortunately Music Player has stopped working" Error when launching App #6

Closed Hansi144 closed 4 years ago

Hansi144 commented 6 years ago

I get that error when trying to launch the app. I have updated the code for the Song class and added a default return null in list_songs.dart at line 67 (my IDE showed it as an error due to the lack of a return statement) There are still some warnings showing up, though no errors. Could they be the reason as to why the app isn't starting ? If so how to fix them ? If not what could be the reason ? I am trying to run it on an emulator with Android API 16. Do I need a higher one ?

Alright I checked and the Android API seemed to have been the problem. Starting with an up to date emulator works. Do you know what the lowest API is possible to use with the app / how to change it ? Also fetching local songs doesnt seem to work it loads forever. I put 3 songs on the emulated device with the android file explorer into sdcard/music/ but it seems the app cant detect them
