我正在尝试在我的android模拟器上创建一个目录但是我不能这样做,我已经拥有了manifest write_storage的权限,并且我没有得到任何错误,但mkdir()返回false,我验证外部存储是否也可写它是,它在物理设备上工作我的代码:

 /// Cria uma nova pasta para colocar o backup
    File direct = new File(Environment.getExternalStorageDirectory(),
            "/Financas RW Backup");
    try {


        if (!direct.exists()) {
            if(isExternalStorageWritable()&&isExternalStorageReadable()) {
              if(  direct.mkdir()) {
                  fachada.showMessage(ExportImportDB.this," Criado");
              }else{
                  fachada.showMessage(ExportImportDB.this," Não Criado");
              }
            }
        }
    } catch (Exception e) {
        fachada.showMessage(this, e.toString());
    }
