- 2 Replies
Hello good morning for everyone I´m a beginner on the Android Studio, and i need a help for you to place well the app, that means working perfectly. It´s a good app, and it could serve me as a example to understand its funcionality.
I´m building an audio music player app., but on my MainActivity.java file ,
In the code i faced with some mistakes, see below the images that i sent you. How could you fix them?
MainActivity.java
AndroidManifest.xml
AlbumFragment.java
MusicFiles.java
fragment_album.xml
SongsFragment.java
fragment_songs.xml
Ps.: I send also the ZIP file about the audio music player app, My Android version is below:
Another trouble is the emulator that in my pc doesn´t work, i think it´s because my Pc doesn´t have the Intel processor but the AMD Processor. Could you help to fix this problem too? see the images
Could anyone, help me, please to fix this problems?
I expect your answer as soon as possible.
Best regards
