Toast on SMS接收ANDROID STUDIO無法正常工作

Question

對於在ANDROID STUDIO中接收短信的Toast演示程序，我沒有得到任何錯誤...但它不適用於我的任何手機（使用三星GT-i9082和聯想a6000 + ）。這裏是我的代碼和清單以下分別......

package com.myapplication.siva.phoneapp; 

import android.content.BroadcastReceiver; 
import android.content.Context; 
import android.content.Intent; 
import android.support.v7.app.ActionBarActivity; 
import android.os.Bundle; 
import android.telephony.SmsMessage; 
import android.util.Log; 
import android.view.Menu; 
import android.view.MenuItem; 
import android.widget.Toast; 


public class MainActivity extends ActionBarActivity{ 
private BroadcastReceiver receiver; 
public static final String SMS_BUNDLE = "pdus"; 
private static String TAG="com.myapplication.siva.phoneapp"; 


@Override 
protected void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.activity_main); 
    Log.i(TAG,"Inside onCreate"); 
    receiver = new BroadcastReceiver() { 
     @Override 
     public void onReceive(Context context, Intent intent) { 
      Bundle intentExtras = intent.getExtras(); 
      Log.i(TAG,"Inside on Receive"); 
      try { 
       Toast.makeText(context, "Coming Inside",Toast.LENGTH_SHORT).show(); 
       Log.i(TAG,"Inside try"); 
       if (intentExtras != null) { 
        Object[] sms = (Object[]) intentExtras.get(SMS_BUNDLE); 
        String smsMessageStr = ""; 
        for (int i = 0; i < sms.length; ++i) { 
         SmsMessage smsMessage = SmsMessage.createFromPdu((byte[]) sms[i]); 

         String smsBody = smsMessage.getMessageBody().toString(); 
         String address = smsMessage.getOriginatingAddress(); 

         smsMessageStr += "SMS From: " + address + "\n"; 
         smsMessageStr += smsBody + "\n"; 
        } 
        Toast.makeText(context, smsMessageStr, Toast.LENGTH_SHORT).show(); 
       } 
      }catch (Exception e) 
      { 
       Log.i(TAG,"Some Exception"); 
      } 
     } 
    }; 
} 


@Override 
public boolean onCreateOptionsMenu(Menu menu) { 
    // Inflate the menu; this adds items to the action bar if it is present. 
    getMenuInflater().inflate(R.menu.menu_main, menu); 
    return true; 
} 

@Override 
public boolean onOptionsItemSelected(MenuItem item) { 
    // Handle action bar item clicks here. The action bar will 
    // automatically handle clicks on the Home/Up button, so long 
    // as you specify a parent activity in AndroidManifest.xml. 
    int id = item.getItemId(); 

    //noinspection SimplifiableIfStatement 
    if (id == R.id.action_settings) { 
     return true; 
    } 

    return super.onOptionsItemSelected(item); 
} 
}

Answer 1

邁克·M是完全正確的意圖過濾器應該包含短信行動，即"android.provider.Telephony.SMS_RECEIVED"沒有別的東西。

其次，你需要一個活動從Android 3.1推出AM廣播接收器的安全問題。
