Question

我为接收短信创建广播接收器。它只适用于应用程序是开放的。当我们从任务管理器中删除应用程序时它无法工作。它在果冻豆，kitkat中工作正常，但在棒棒糖版本中不起作用。

    public class MobiricReceiver extends BroadcastReceiver {

    // Get the object of SmsManager
    final SmsManager sms = SmsManager.getDefault();

    public void onReceive(Context context, Intent intent) {

        // Retrieves a map of extended data from the intent.
        final Bundle bundle = intent.getExtras();

        try {

            if (bundle != null) {

                final Object[] pdusObj = (Object[]) bundle.get("pdus");

                for (int i = 0; i < pdusObj.length; i++) {

                    SmsMessage currentMessage = SmsMessage.createFromPdu((byte[]) pdusObj[i]);
                    String phoneNumber = currentMessage.getDisplayOriginatingAddress();

                    String senderNum = phoneNumber;
                    String message = currentMessage.getDisplayMessageBody();

                    Log.i("SmsReceiver", "senderNum: " + senderNum + "; message: " + message);


                    // Show Alert
                    int duration = Toast.LENGTH_LONG;
                    Toast toast = Toast.makeText(context,
                            "senderNum: "+ senderNum + ", message: " + message, duration);
                    toast.show();

                } // end for loop
            } // bundle is null

        } catch (Exception e) {
            Log.e("SmsReceiver", "Exception smsReceiver" +e);

        }
    }
}

这是一个非常简单的解决方案。在Menifest中添加这个 - ＆gt;活动标签

        <activity
        android:name=".MainActivity"
        android:label="@string/app_name"
        android:screenOrientation="portrait"
        android:autoRemoveFromRecents="true">
        </activity>

在按下Back按钮时，请使用此代码完成活动

 if(android.os.Build.VERSION.SDK_INT >= 21)
                            {
                                getActivity().finishAndRemoveTask();
                            }
                            else
                            {
                                getActivity().finish();
                            }

当应用程序从棒棒糖中的任务管理器关闭时，广播接收器不工作
