您广播接收器即ReceivesmsActivity和活动即ReceivesmsActivity是具有相同的名称可能会引起问题,所以只是改变以不同的名称注册您的短信接收器:
<接收机器人:名字=。ReceivesmsBroadcast>
&所述;意图滤光器>
<作用机器人:名字=android.provider.Telephony.SMS_RECEIVED/>
&所述; /意图滤光器>
< /接收器>
在code创建一个类ReceivesmsBroadcast.java:
公共类ReceivesmsBroadcast扩展广播接收器{ 私有静态最后弦乐TAG =消息收到; @覆盖
公共无效的onReceive(上下文的背景下,意图意图){
///您的code去这里 }
}
Facing the Unable to instantiate activity ComponentInfo problem while launching the SMS Receiver Application. Could any tell me what i am doing wrong????
<?xml version="1.0" encoding="utf-8"?><manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.raja.receivesms"
android:versionCode="1"
android:versionName="1.0.0">
<application android:icon="@drawable/ic_launcher" android:label="@string/app_name">
<activity android:name=".ReceivesmsActivity"
android:label="@string/app_name">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<receiver android:name=".ReceivesmsActivity">
<intent-filter>
<action android:name="android.provider.Telephony.SMS_RECEIVED" />
</intent-filter>
</receiver>
</application>
<uses-permission android:name="android.permission.RECEIVE_SMS">
</uses-permission>
<uses-sdk android:minSdkVersion="8" /></manifest>
And class file as follows ReceivesmsActivity.java
package com.raja.receivesms;
import android.content.*;
import android.os.Bundle;
import android.telephony.SmsMessage;
import android.util.Log;
import android.widget.Toast;
import android.content.Intent;
public class ReceivesmsActivity extends BroadcastReceiver {
private static final String TAG = "Message recieved";
@Override
public void onReceive(Context context, Intent intent) {
Bundle bundle = intent.getExtras();
SmsMessage[] msgs = null;
String str = "";
if (bundle != null)
{
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]);
str += "SMS from " + msgs[i].getOriginatingAddress();
str += " :";
str += msgs[i].getMessageBody().toString();
str += "\n";
}
Toast.makeText(context, str, Toast.LENGTH_SHORT).show();
}
}
}
Your BroadcastReceiver i.e ReceivesmsActivity and Activity i.e ReceivesmsActivity is with same name may be causing problem so just change to different name register your sms receiver as:
<receiver android:name=".ReceivesmsBroadcast">
<intent-filter>
<action android:name="android.provider.Telephony.SMS_RECEIVED" />
</intent-filter>
</receiver>
and in code create a class ReceivesmsBroadcast.java:
public class ReceivesmsBroadcast extends BroadcastReceiver {
private static final String TAG = "Message recieved";
@Override
public void onReceive(Context context, Intent intent) {
/// your code go here
}
}
