Hi everyone, I am a beginner in app inventor2. I am Chinese, so my English is not very good. I used google to help translate it, if the translation is not good, please include it.
I checked your examples and related books, but I still can't get the app invnteor2 to read the mp3 in the sd and play it smoothly.
Below is the path inside the phone, and the coding trick I'm trying to read.
Please answer me where is the problem, thank you.
