You can put below codes in your project when you want to select audio.
Intent intent_upload = new Intent();
intent_upload.setType("audio/*");
intent_upload.setAction(Intent.ACTION_GET_CONTENT);
startActivityForResult(intent_upload,1);
And override onActivityResult in the same Activity, as below
@Override
protected void onActivityResult(int requestCode,int resultCode,Intent data){
if(requestCode == 1){
if(resultCode == RESULT_OK){
//the selected audio.
Uri uri = data.getData();
}
}
super.onActivityResult(requestCode, resultCode, data);
}
