Question

这是我发送短信的代码。我已经调用了unregisterReceiver（接收器）方法，但我仍然在logcat中收到此错误。

Intent Receiver leaked that was originally register here. Are you missing to call 
unregisterReciever() ?

这是我的代码：

public static void sendSMS(final Context context, final String phoneNumber, final String message) {
    String SENT = "SMS_SENT";
    String DELIVERED = "SMS_DELIVERED";

    PendingIntent sentPI = PendingIntent.getBroadcast(context, 0, new Intent(
            SENT), 0);

    PendingIntent deliveredPI = PendingIntent.getBroadcast(context, 0,
            new Intent(DELIVERED), 0);

    // ---when the SMS has been sent---
     context.registerReceiver(new BroadcastReceiver() {
        @Override
        public void onReceive(Context arg0, Intent arg1) {
            context.unregisterReceiver(this);
            switch (getResultCode()) {
            case Activity.RESULT_OK:
                ContentValues values = new ContentValues();
                values.put("address", phoneNumber);// txtPhoneNo.getText().toString());
                values.put("body", message);
                context.getContentResolver().insert(sentURI, values);
                Toast.makeText(context, "SMS sent", Toast.LENGTH_SHORT).show();
                break;
            case SmsManager.RESULT_ERROR_GENERIC_FAILURE:
                Toast.makeText(context, "Generic failure",
                        Toast.LENGTH_SHORT).show();
                break;
            case SmsManager.RESULT_ERROR_NO_SERVICE:
                Toast.makeText(context, "No service",
                        Toast.LENGTH_SHORT).show();
                break;
            case SmsManager.RESULT_ERROR_NULL_PDU:
                Toast.makeText(context, "Null PDU",
                        Toast.LENGTH_SHORT).show();
                break;
            case SmsManager.RESULT_ERROR_RADIO_OFF:
                Toast.makeText(context, "Radio off",
                        Toast.LENGTH_SHORT).show();
                break;
            }

        }
    }, new IntentFilter(SENT));

    // ---when the SMS has been delivered---
    context.registerReceiver(new BroadcastReceiver() {
        @Override
        public void onReceive(Context arg0, Intent arg1) {
            context.unregisterReceiver(this);
            switch (getResultCode()) {
            case Activity.RESULT_OK:
                Toast.makeText(context, "SMS delivered",
                        Toast.LENGTH_SHORT).show();
                break;
            case Activity.RESULT_CANCELED:
                Toast.makeText(context, "SMS not delivered",
                        Toast.LENGTH_SHORT).show();
                break;
            }

        }


    }, new IntentFilter(DELIVERED));

    SmsManager sms = SmsManager.getDefault();
    sms.sendTextMessage(phoneNumber, null, message, sentPI, deliveredPI);
}

请注意，短信会被发送和传送，而且我在广播接收器上收到相同的错误信息。

Answer 1

您每次注册BroadcastReceiver的新匿名实例，然后取消注册BroadcastReceiver的新实例，但这将与您注册的实例不同。

您需要将此匿名变量设为类变量，然后在该引用上调用register / unregister。

同时确保您在补充方法中注册/取消注册：

onCreate() / onDestroy()
onResume() / onPause()

注册如：

BroadcastReceiver receiver=new BroadcastReceiver() {
    @Override
    public void onReceive(Context arg0, Intent arg1) {
        context.unregisterReceiver(this);
        switch (getResultCode()) {
        case Activity.RESULT_OK:
            ContentValues values = new ContentValues();
            values.put("address", phoneNumber);// txtPhoneNo.getText().toString());
            values.put("body", message);
            context.getContentResolver().insert(sentURI, values);
            Toast.makeText(context, "SMS sent", Toast.LENGTH_SHORT).show();
            break;
        case SmsManager.RESULT_ERROR_GENERIC_FAILURE:
            Toast.makeText(context, "Generic failure",
                    Toast.LENGTH_SHORT).show();
            break;
        case SmsManager.RESULT_ERROR_NO_SERVICE:
            Toast.makeText(context, "No service",
                    Toast.LENGTH_SHORT).show();
            break;
        case SmsManager.RESULT_ERROR_NULL_PDU:
            Toast.makeText(context, "Null PDU",
                    Toast.LENGTH_SHORT).show();
            break;
        case SmsManager.RESULT_ERROR_RADIO_OFF:
            Toast.makeText(context, "Radio off",
                    Toast.LENGTH_SHORT).show();
            break;
        }

    }
}

onResume中的

：

context.registerReceiver(receiver,new IntentFilter(SENT));

和onPause

context.unregisterReceiver(receiver);

泄漏的意图接收器
