Android 当收到来自特定号码的消息时，从sms广播接收器启动活动

我关注了很多链接，但仍然找不到解决问题的方法。基本上，我有两个类

UsingBroadcastReceiver

和

StartAction

。当我收到来自特定号码的消息时，我需要启动

StartAction

活动。为此，我实现了以下代码。 更新代码：-

public class UsingBroadcastReceiver extends BroadcastReceiver {

final SmsManager sms = SmsManager.getDefault();

String body = null;
String no = "15555215558";


@Override
public void onReceive(Context context, Intent intent) {
    // Parse the SMS.
    Bundle bundle = intent.getExtras();
    SmsMessage[] msgs = null;
    String str = "";
    if (bundle != null)
    {
        // Retrieve the SMS.
        Object[] pdus = (Object[]) bundle.get("pdus");
        msgs = new SmsMessage[pdus.length];
        for (int i=0; i<msgs.length; i++)
        {
            msgs[i] = SmsMessage.createFromPdu((byte[])pdus[i]);

            if(msgs[i].getOriginatingAddress().equals(no))
            {
                body = msgs[i].getMessageBody();

            str += "SMS from " + msgs[i].getOriginatingAddress();
            str += " :";
            str += msgs[i].getMessageBody().toString();
            str += "\n";

            Intent open = new Intent(context, StartAction.class);
            open.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
            open.putExtra("body", body);
            context.startActivity(open);
            }
        }
        // Display the SMS as Toast.
        Toast.makeText(context, str, Toast.LENGTH_SHORT).show();
    }
}

此外，我还需要在

StartAction

类中使用BroadcastReceiver类访问

的字符串体的值。这是正确的方法吗

StartAction start = new StartAction();
            start.msgBody = body;

我的舱单如下：

我仍然收到相同日志的相同强制关闭错误消息为什么使用此循环中的Intent open=new Intent（上下文，StartAction.class）；open.addFlags（Intent.FLAG\u ACTIVITY\u NEW\u TASK）；open.putExtra（“body”，body）；背景。起始触觉（开放）；然后把你的StartAction.class代码贴出来，我想你在StartAction.class没有收到包裹。。我把它从循环中去掉了。现在开始工作了。谢谢：）不过是个小问题。。当收到短信时，它工作得非常好。但如果我试图通过点击d图标手动启动此应用程序，它将强制关闭。知道如何避免这种情况吗？我仍然收到相同的force close错误消息，带有相同的logcatwhy使用这个in-loop Intent open=new Intent（context，StartAction.class）；open.addFlags（Intent.FLAG\u ACTIVITY\u NEW\u TASK）；open.putExtra（“body”，body）；背景。起始触觉（开放）；然后把你的StartAction.class代码贴出来，我想你在StartAction.class没有收到包裹。。我把它从循环中去掉了。现在开始工作了。谢谢：）不过是个小问题。。当收到短信时，它工作得非常好。但如果我试图通过点击d图标手动启动此应用程序，它将强制关闭。你知道如何避免这种情况吗？
