我想要extends BroadcastReceiver
首先用jsoup讀取一個網站然後(檢查某些東西然後)發出通知的類。 因爲具有jsoup的部分需要AsyncTask
,所以通知代碼需要位於AsyncTask onPostExecute
部分,但應用程序會在Alarm
或Calendar
代碼給出的時間崩潰。Android:在Asynctask中發送通知 - >崩潰
extends
BroadcastReceiver
如果通知碼不在extends AsyncTask
的類中,該類的代碼將起作用。
這是NotificationClass的現在的代碼:
public class NotificationClass extends BroadcastReceiver{
Context specialContext;
int MID = 1;
long when = System.currentTimeMillis();
Uri alarmSound = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);
@Override
public void onReceive(Context context, Intent intent) {
// TODO Auto-generated method stub
new loadText().execute();
}
public class loadText extends AsyncTask<Void, Void, Void>
{
String siteText;
@Override
protected Void doInBackground(Void... params) {
Connection.Response res = null;
try {
res = Jsoup.connect("http://www.hpg-speyer.de/vertretungsplan/") // Link der Hauptseite, wo auch der Login ist
.data("authid", "22101999AzaKur", "authpw", "451d28") // Hier wären dann die Daten eingetragen
.method(Connection.Method.POST)
.execute();
} catch (Exception e) {
e.printStackTrace();
}
try {
Document doc = res.parse();
} catch (Exception e) {
e.printStackTrace();
}
String sessionId = res.cookie("PHPSESSID"); // Name des Cookies
Document doc2 = null;
try {
doc2 = Jsoup.connect("http://www.hpg-speyer.de/vertretungsplan/") // das wäre der Link zu den Feldern
.cookie("PHPSESSID", sessionId)
.get();
siteText = doc2.text();
} catch (Exception e) {
e.printStackTrace();
}
return null;
}
@Override
protected void onPostExecute(Void aVoid) {
super.onPostExecute(aVoid);
NotificationManager notificationManager = (NotificationManager) specialContext
.getSystemService(Context.NOTIFICATION_SERVICE);
Intent notificationIntent = new Intent(specialContext, MainActivity.class);
notificationIntent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
PendingIntent pendingIntent = PendingIntent.getActivity(specialContext, 0,
notificationIntent, PendingIntent.FLAG_UPDATE_CURRENT);
NotificationCompat.Builder mNotifyBuilder = (NotificationCompat.Builder) new NotificationCompat.Builder(
specialContext).setSmallIcon(R.mipmap.ic_launcher)
.setContentTitle("Alarm Fired")
.setContentText("Events To be PErformed").setSound(alarmSound)
.setAutoCancel(true).setWhen(when)
.setContentIntent(pendingIntent)
.setVibrate(new long[]{1000, 1000, 1000, 1000, 1000});
if (siteText.contains("something")) {
notificationManager.notify(MID, mNotifyBuilder.build());
MID++;
}
}
}}

我如何發現崩潰:
我坐日曆的時間與某事有關然後運行應用程序,並在虛擬設備上彈出並觀察後關閉它。 此方法沒有使用AsyncTask
,也沒有顯示消息:「HPG Vertretungsplan已停止」,但收到通知。
在此先感謝。
在此處發佈您的崩潰日誌 –
向我們顯示日誌。爲什麼你想使用廣播接收機? – xFighter
我猜這是'siteText',在這種情況下應該爲null,儘管崩潰日誌有助於確認我的猜測。 – Darpan
