Question

我使用简单的BroadcastReceiver和onReceive方法拦截文本消息。出于某种原因，每次我发送短信时：应用程序崩溃。当我尝试调试应用程序时：我发送文本消息并且应用程序仍然崩溃，但不是将我带入Receiver类，而是暂停在“ActivityThreadhandleReceiver（ActivityThread，ActivityThreadReceiverData）”内部。 Debugging窗口只是为Thread说：“（Suspended（异常RuntimeException））”。

如果我的应用程序不允许我单步执行代码，我该怎么知道我的应用程序崩溃的原因。

这是我的Receiver Class：

public class FinderReciever extends BroadcastReceiver {


@Override
public void onReceive(Context context, Intent intent)
{
Bundle bundle = intent.getExtras();
SmsMessage[ ] msgs = null;
String str = "";
if (bundle != null)
{
//---retrieve the received message here ---
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";
}
// ........first show sms here.....
Toast.makeText(context, str, Toast.LENGTH_SHORT).show();
}

这是我的清单：

<?xml version="1.0" encoding="utf-8"?>

<application android:icon="@drawable/icon" android:label="@string/app_name">
    <activity android:name=".PhoneFinder_Activity"
              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=".SmsReceiver">
    <intent-filter>
    <action android:name=
        "android.provider.Telephony.SMS_RECEIVED" />
    </intent-filter>
    </receiver> 
</application>

<uses-permission android:name="android.permission.READ_SMS" />
<uses-permission android:name="android.permission.RECEIVE_SMS" />

非常感谢任何帮助。谢谢！

编辑：即使重新格式化方法以在我的主Activity中运行，我也得到完全相同的结果。这个完全相同的方法适用于发送文本Intent：

        String SENT = "SMS_SENT";
    String DELIVERED = "SMS_DELIVERED";
    String RECEIVED = "SMS_RECEIVED";


    PendingIntent sentPI = PendingIntent.getBroadcast(this, 0,
        new Intent(SENT), 0);

    PendingIntent deliveredPI = PendingIntent.getBroadcast(this, 0,
        new Intent(DELIVERED), 0);

    PendingIntent receivedPI = PendingIntent.getBroadcast(this, 0, new Intent(RECEIVED), 0);

    //---when the SMS has been sent---
    registerReceiver(new BroadcastReceiver(){
        @Override
        public void onReceive(Context arg0, Intent arg1) {
            switch (getResultCode())
            {
                case Activity.RESULT_OK:
                    Toast.makeText(getBaseContext(), "FRIGGEN SMS!", 
                            Toast.LENGTH_SHORT).show();
                    break;
                case SmsManager.RESULT_ERROR_GENERIC_FAILURE:
                    Toast.makeText(getBaseContext(), "Generic failure", 
                            Toast.LENGTH_SHORT).show();
                    break;
                case SmsManager.RESULT_ERROR_NO_SERVICE:
                    Toast.makeText(getBaseContext(), "No service", 
                            Toast.LENGTH_SHORT).show();
                    break;
                case SmsManager.RESULT_ERROR_NULL_PDU:
                    Toast.makeText(getBaseContext(), "Null PDU", 
                            Toast.LENGTH_SHORT).show();
                    break;
                case SmsManager.RESULT_ERROR_RADIO_OFF:
                    Toast.makeText(getBaseContext(), "Radio off", 
                            Toast.LENGTH_SHORT).show();
                    break;
            }
        }
    }, new IntentFilter(RECEIVED));

清单文件中有错误 - 接收方的名称必须是类的名称。因此，对于上面的FinderReciever类，您需要：

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

您还可以通过查看logcat来验证这是否是问题。你应该看到类似的东西：

ERROR/AndroidRuntime(1708): FATAL EXCEPTION: main
ERROR/AndroidRuntime(1708): java.lang.RuntimeException: Unable to instantiate receiver xxx.xxxx.SmsReceiver: java.lang.ClassNotFoundException: ....
