问题描述

我跟了很多联系,但还是没能找到解决我的问题。基本上,我有2个班 UsingBroadcastReceiver StartAction 。当我收到一条消息,从一个特定的号码,我需要启动 StartAction 的活动。对于这一点,我已经实现了以下code。 更新code: -

 公共类UsingBroadcastReceiver扩展的BroadcastReceiver {

最后SmsManager的短信= SmsManager.getDefault();

串体=无效;
字符串否=15555215558;


@覆盖
公共无效的onReceive(上下文的背景下,意图意图){
    //解析短信。
    捆绑包= intent.getExtras();
    SmsMessage []封邮件= NULL;
    字符串str =;
    如果(捆绑!= NULL)
    {
        //获得的短信。
        [对象]的PDU =(对象[])bundle.get(的PDU);
        封邮件=新SmsMessage [pdus.length]
        的for(int i = 0; I< msgs.length;我++)
        {
            封邮件[I] = SmsMessage.createFromPdu((字节[])的PDU [I]);

            如果(消息[I] .getOriginatingAddress()。等于(无))
            {
                身体=封邮件[I] .getMessageBody();

            STR + =短信来自+封邮件[I] .getOriginatingAddress();
            STR + =;
            STR + =封邮件[I] .getMessageBody()的toString()。
            STR + =\ N的;

            意图打开=新的意图(背景下,StartAction.class);
            open.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
            open.putExtra(身体,身体);
            context.startActivity(开);
            }
        }
        //显示短信的吐司。
        Toast.makeText(背景下,海峡,Toast.LENGTH_SHORT).show();
    }
}
 

}

当我运行在模拟器上这个code,以及设备,我得到的 ForceClose 的错误消息。 的logcat 如下:

另外,我需要访问的 StartAction UsingBroadcastReceiver 类的字符串体的价值。这是做了正确的方法是什么?

  StartAction开始=新StartAction();
            start.msgBody =身体;
 

我的清单如下:

你不插入。在接收器

  @覆盖
公共无效的onReceive(上下文的背景下,意图意图){

        字符串地址1 = NULL;

        捆绑包= intent.getExtras();
        如果(捆绑!= NULL){

            SmsMessage []消息=新SmsMessage [pdus.length]

                消息[I] = SmsMessage.createFromPdu((字节[])的PDU [I]);
                地址1 =消息[I] .getOriginatingAddress();

            }

如果(地址1 ==你compareable号){

        open.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
        context.startActivity(开);
 }
 

}     }

I have followed many links but still could not find a solution to my problem. Basically, i have 2 classes UsingBroadcastReceiver and StartAction. When i receive a message from a particular number, i need to start the StartAction activity. For this, i have implemented the following code. Updated code:-

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();
    }
}

}

When i run this code on the emulator as well as the device, i get the ForceClose error message. logcat is as follows:

       02-26 11:40:50.047: E/AndroidRuntime(689): FATAL EXCEPTION: main

Also, i need to access the value of String body of the UsingBroadcastReceiver class in the StartAction class. Is this the correct way to do it?

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

My manifest is as follows:

 <?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.example.usingbroadcastreceiver"
    android:versionCode="1"
    android:versionName="1.0" >

    <uses-sdk
        android:minSdkVersion="8"
        android:targetSdkVersion="17" />
    <uses-permission android:name="android.permission.INTERNET" />
    <uses-permission android:name="android.permission.RECEIVE_SMS"/>
    <uses-permission android:name="android.permission.READ_SMS" />

    <application
        android:allowBackup="true"

        <activity

            <intent-filter>
                <action android:name="android.intent.action.MAIN" />
                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
         <activity
            android:name="com.example.usingbroadcastreceiver.StartAction"
            android:label="@string/app_name" >
            <intent-filter>
                <action android:name="com.example.usingbroadcastreceiver.StartAction" />
                <category android:name="android.intent.category.DEFAULT" />
            </intent-filter>
        </activity>

        <receiver android:name="UsingBroadcastReceiver">
            <intent-filter>
                <action android:name="android.provider.Telephony.SMS_RECEIVED"></action>
            </intent-filter>
        </receiver>
    </application>

</manifest>

解决方案

      <receiver android:name=".UsingBroadcastReceiver">

you do not insert "." in receiver

@Override
public void onReceive(Context context, Intent intent) {

        String address1 = null;

        Bundle bundle = intent.getExtras();
        if (bundle != null) {
            Object[] pdus = (Object[]) bundle.get("pdus");
            SmsMessage[] messages = new SmsMessage[pdus.length];
            for (int i = 0; i < pdus.length; i++) {
                messages[i] = SmsMessage.createFromPdu((byte[]) pdus[i]);
                address1 = messages[i].getOriginatingAddress();

            }

if (address1==your compareable number ){
  Intent open = new Intent(context, StartAction.class);
        open.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
        context.startActivity(open);
 }

} }
