我正在使用此代碼發送短信。廣播接收機崩潰了一些時間android
private void sendSMS(String phoneNumber, String message) {
System.out.println("SMS: " + message);
System.out.println("to " + phoneNumber);
String SENT = "SMS_SENT";
String DELIVERED = "SMS_DELIVERED";
PendingIntent sentPI = PendingIntent.getBroadcast(this, 0, new Intent(
SENT), 0);
PendingIntent deliveredPI = PendingIntent.getBroadcast(this, 0,
new Intent(DELIVERED), 0);
// ---when the SMS has been sent---
registerReceiver(new BroadcastReceiver() {
@Override
public void onReceive(Context arg0, Intent arg1) {
switch (getResultCode()) {
case Activity.RESULT_OK:
Toast.makeText(getBaseContext(), "SMS sent",
Toast.LENGTH_SHORT).show();
break;
case SmsManager.RESULT_ERROR_GENERIC_FAILURE:
Toast.makeText(getBaseContext(), "Generic failure",
Toast.LENGTH_SHORT).show();
break;
case SmsManager.RESULT_ERROR_NO_SERVICE:
Toast.makeText(getBaseContext(), "No service",
Toast.LENGTH_SHORT).show();
break;
case SmsManager.RESULT_ERROR_NULL_PDU:
Toast.makeText(getBaseContext(), "Null PDU",
Toast.LENGTH_SHORT).show();
break;
case SmsManager.RESULT_ERROR_RADIO_OFF:
Toast.makeText(getBaseContext(), "Radio off",
Toast.LENGTH_SHORT).show();
break;
}
}
}, new IntentFilter(SENT));
// ---when the SMS has been delivered---
registerReceiver(new BroadcastReceiver() {
@Override
public void onReceive(Context arg0, Intent arg1) {
switch (getResultCode()) {
case Activity.RESULT_OK:
Toast.makeText(getBaseContext(), "SMS delivered",
Toast.LENGTH_SHORT).show();
break;
case Activity.RESULT_CANCELED:
Toast.makeText(getBaseContext(), "SMS not delivered",
Toast.LENGTH_SHORT).show();
break;
}
}
}, new IntentFilter(DELIVERED));
// SmsManager sms = SmsManager.getDefault();
// sms.sendTextMessage(phoneNumber, null, message, sentPI, deliveredPI);
SmsManager sm = SmsManager.getDefault();
ArrayList<String> parts = sm.divideMessage(message);
int numParts = parts.size();
ArrayList<PendingIntent> sentIntents = new ArrayList<PendingIntent>();
ArrayList<PendingIntent> deliveryIntents = new ArrayList<PendingIntent>();
for (int i = 0; i < numParts; i++) {
sentIntents.add(sentPI);
deliveryIntents.add(deliveredPI);
}
sm.sendMultipartTextMessage(phoneNumber, null, parts, sentIntents,
deliveryIntents);
}
}
有時候，我得到這個錯誤，而其他時候，它發揮正常全無錯誤可言：

我需要在我的XML文件中或在我的OnDestry功能添加任何東西？因爲我不喜歡廣播接收機。爲什麼它有時會播放，有些則不是？
