如何解决FirebaseMessagingService冻结
是否可以防止android系统停止 private void btn_Salva_Click(object sender,EventArgs e)
{
var listadasalvare = dataGridView1.DataSource as List<Rubrica>;
var listaJson = JsonConvert.SerializeObject(listadasalvare);
// indico direttamente il percorso senza richiamare la finestra
// di salvataggio
var path = @"D:\OneDrive\Corso di c# informatica\Rubricajsonformato.txt";
File.WriteallText(path,listaJson);
}
private void Form1_Load(object sender,EventArgs e)
{
var formcreate = ClientiDataManager.GetClienti();
var telefonia = new BindingList<Rubrica>();
foreach (var campo in formcreate)
{
var nuovatelefonia = new Rubrica();
nuovatelefonia.IdScheda = campo.IdScheda;
nuovatelefonia.Intestatario = campo.Intestatario;
nuovatelefonia.NumeroTelefono = campo.NumeroTelefono;
nuovatelefonia.Scadenza = campo.Scadenza;
telefonia.Add(nuovatelefonia);
}
dataGridView1.DataSource = telefonia;
}
？
一段时间后，我们的测试设备会停止在后台接收通知。根据日志：

权限的请求。通知中肯定包含REQUEST_IGnorE_BATTERY_OPTIMIZATIONS字段。一切都是根据official documentation
