startForegroundService 閃退問題

1 NotificationCompat

//通知顯示
PendingIntent contentIntent = PendingIntent.getService(this, 0, intent, 0);
NotificationCompat.Builder builder = new NotificationCompat.Builder(this);
builder.setTicker("SMS")
        .setPriority(Notification.PRIORITY_MIN)
        .setContentIntent(contentIntent)
        .setContentTitle("我怕誰!")
        .setAutoCancel(true)
        .setContentText("SMSContext")
        .setWhen(System.currentTimeMillis());

//把service設置爲前臺運行，避免手機系統自動殺掉改服務。
startForeground(startId, builder.build());



或者
Notification.Builder builder = new Notification.Builder(this);
builder.setSmallIcon(R.mipmap.ic_launcher);
builder.setChannelId(CHANNEL_ONE_ID);
builder.setContentTitle("SMS");
builder.setContentText("SMSListener is runing...");
startForeground(NOTICE_ID,builder.build());



複製代碼

2 再次啓動Service

//兼容版本服務
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
    //8.0上啓動前臺服務
    startForegroundService(new Intent(this, ChannlService.class));
    tv_runstatus.postDelayed(new Runnable() {
        @Override
        public void run() {
            startService(new Intent(MainActivity.this, ChannlService.class));
        }
    }, 500);

} else {
    startService(new Intent(this, ChannlService.class));
}複製代碼

避免了用戶看到通知欄，也是前臺服務 onstartCommon會調用兩次，本身處理下邏輯判斷便可
