  1. POProblem sending port-directed Data SMS on HTC EVO 4G
    text
    copied!<p>I am trying to send and receive port-directed SMS from an HTC EVO 4G to itself using <code>SmsManager.sendDataMessage()</code> and the device is giving a NullPointerException quite deep in the OS.</p> <p>Here is the code that kicks off the exception:</p> <pre><code>manager.sendDataMessage(phonenumber, null, (short) 8091, data,piSend, piDelivered); </code></pre> <p>I think I have the appropriate permissions declared in the manifest:</p> <pre><code>&lt;uses-permission android:name="android.permission.READ_SMS"&gt;&lt;/uses-permission&gt; &lt;uses-permission android:name="android.permission.SEND_SMS"&gt;&lt;/uses-permission&gt; &lt;uses-permission android:name="android.permission.RECEIVE_SMS"&gt;&lt;/uses-permission&gt; </code></pre> <p>Here's the stack trace I'm getting:</p> <pre><code>06-27 11:03:42.144: ERROR/AndroidRuntime(14489): FATAL EXCEPTION: main 06-27 11:03:42.144: ERROR/AndroidRuntime(14489): java.lang.NullPointerException 06-27 11:03:42.144: ERROR/AndroidRuntime(14489): at android.os.Parcel.readException(Parcel.java:1328) 06-27 11:03:42.144: ERROR/AndroidRuntime(14489): at android.os.Parcel.readException(Parcel.java:1276) 06-27 11:03:42.144: ERROR/AndroidRuntime(14489): at com.android.internal.telephony.ISms$Stub$Proxy.sen dData(ISms.java:682) 06-27 11:03:42.144: ERROR/AndroidRuntime(14489): at android.telephony.SmsManager.sendDataMessage(SmsMa nager.java:546) 06-27 11:03:42.144: ERROR/AndroidRuntime(14489): at com.varma.samples.smsdemo.MainActivity.sendSms(Mai nActivity.java:66) 06-27 11:03:42.144: ERROR/AndroidRuntime(14489): at com.varma.samples.smsdemo.MainActivity.access$0(Ma inActivity.java:50) 06-27 11:03:42.144: ERROR/AndroidRuntime(14489): at com.varma.samples.smsdemo.MainActivity$1.onClick(M ainActivity.java:98) 06-27 11:03:42.144: ERROR/AndroidRuntime(14489): at android.view.View.performClick(View.java:2532) 06-27 11:03:42.144: ERROR/AndroidRuntime(14489): at android.view.View$PerformClick.run(View.java:9293) 06-27 11:03:42.144: ERROR/AndroidRuntime(14489): at android.os.Handler.handleCallback(Handler.java:587 ) 06-27 11:03:42.144: ERROR/AndroidRuntime(14489): at android.os.Handler.dispatchMessage(Handler.java:92 ) 06-27 11:03:42.144: ERROR/AndroidRuntime(14489): at android.os.Looper.loop(Looper.java:143) 06-27 11:03:42.144: ERROR/AndroidRuntime(14489): at android.app.ActivityThread.main(ActivityThread.jav a:4263) 06-27 11:03:42.144: ERROR/AndroidRuntime(14489): at java.lang.reflect.Method.invokeNative(Native Method) 06-27 11:03:42.144: ERROR/AndroidRuntime(14489): at java.lang.reflect.Method.invoke(Method.java:507) 06-27 11:03:42.144: ERROR/AndroidRuntime(14489): at com.android.internal.os.ZygoteInit$MethodAndArgsCa ller.run(ZygoteInit.java:839) 06-27 11:03:42.144: ERROR/AndroidRuntime(14489): at com.android.internal.os.ZygoteInit.main(ZygoteInit .java:597) 06-27 11:03:42.144: ERROR/AndroidRuntime(14489): at dalvik.system.NativeStart.main(Native Method) </code></pre> <p>If anybody wants to try it out for themselves, I am using the example provided <a href="http://code.google.com/p/krvarma-android-samples/source/browse/" rel="nofollow">here in the SMSDemo project</a>.</p> <p>Can anybody help me out with this?</p> <p><strong>EDIT :</strong> I have just put together a sample J2ME MIDlet to see if I can get it to work as well and it also fails. Does anybody remember any information about port-directed SMS? Is it handled differently on different networks? Is it all just outdated and I need to get with the times? Or is it something that I might be doing?</p> <p>In case SMS is network dependent, I'm using Sprint devices but I'm developing in Canada, so I think they are roaming on Telus.</p>
