Question

我正在做一个阻止某些电话的应用程序。我有一个广播接收器来解决此问题。但是，当我（手动或按系统）杀死我的应用程序时，接收器不起作用。

我以为我需要一种执行广播接收器或阻止其自身调用的服务。我该怎么办？

谢谢你的优势。

编辑我的接收器课程：

Dim N As Long
Dim wsName As String

For N = 1 To ThisWorkbook.Sheets.Count
    wsName = ThisWorkbook.Worksheets(N).Name

    If Len(wsName) = 3 Then
        'command
        Call blank
        Call hide

    Else 'do nothing

    End If
Next N

Sub blank()
    Range("T2").Select
    ActiveCell.FormulaR1C1 = "=IF(RC[-3]<>"""",RC[-2]="""",""FALSE"")"
    Range("T2").Select
    Selection.AutoFill Destination:=Range("T2:T6999")
End Sub

Sub hide()
    Columns("T:T").Select
    Selection.EntireColumn.Hidden = True
End Sub

我的接收者清单：

public class IncomingCallReceiver extends BroadcastReceiver {
@Override
public void onReceive(Context context, Intent intent) {

    ITelephony telephonyService;
    try {
        String state = intent.getStringExtra(TelephonyManager.EXTRA_STATE);
        String number = intent.getExtras().getString(TelephonyManager.EXTRA_INCOMING_NUMBER);


        if (state.equalsIgnoreCase(TelephonyManager.EXTRA_STATE_RINGING)) {
            TelephonyManager tm = (TelephonyManager) context.getSystemService(Context.TELEPHONY_SERVICE);
            try {
                Method m = tm.getClass().getDeclaredMethod("getITelephony");


                m.setAccessible(true);
                telephonyService = (ITelephony) m.invoke(tm);


                if ((number != null)) {
                    telephonyService.endCall();
                    Toast.makeText(context, "Ending the call from: " + number, Toast.LENGTH_SHORT).show();
                }


            } catch (Exception e) {
                e.printStackTrace();
            }


            Toast.makeText(context, "Ring " + number, Toast.LENGTH_SHORT).show();


        }
        if (state.equalsIgnoreCase(TelephonyManager.EXTRA_STATE_OFFHOOK)) {
            Toast.makeText(context, "Answered " + number, Toast.LENGTH_SHORT).show();
        }
        if (state.equalsIgnoreCase(TelephonyManager.EXTRA_STATE_IDLE)) {
            Toast.makeText(context, "Idle " + number, Toast.LENGTH_SHORT).show();
        }
    } catch (Exception e) {
        e.printStackTrace();
    }
}

应用被杀死时执行BroadcastReceiver Android
