    <p>I have a strange error with the code below: all is working fine for hours, but sometimes I have an exception and my app closes.</p> <p>This is my piece of code that I call very frequently (every 15 seconds)</p> <pre><code>String URL = wscfg.server_address + "/xmds.php"; SoapObject localSoapObject = new SoapObject("", "registerDisplay"); localSoapObject.addProperty("serverKey", wscfg.server_key); localSoapObject.addProperty("hardwareKey", wscfg.hardware_key); localSoapObject.addProperty("version", wscfg.server_version); localSoapObject.addProperty("displayName", wscfg.device_name); SoapSerializationEnvelope localSoapSerializationEnvelope = new SoapSerializationEnvelope(SoapEnvelope.VER11); localSoapSerializationEnvelope.bodyOut = localSoapObject; new HttpTransportSE(URL).call("", localSoapSerializationEnvelope); String s = (String)localSoapSerializationEnvelope.getResponse(); </code></pre> <p>The exception is:</p> <pre><code>01-22 13:33:55.048: E/AndroidRuntime(567): FATAL EXCEPTION: Timer-5 01-22 13:33:55.048: E/AndroidRuntime(567): java.lang.NullPointerException 01-22 13:33:55.048: E/AndroidRuntime(567): at org.ksoap2.transport.ServiceConnectionSE.getResponseProperties(ServiceConnectionSE.java:85) 01-22 13:33:55.048: E/AndroidRuntime(567): at org.ksoap2.transport.HttpTransportSE.call(HttpTransportSE.java:189) 01-22 13:33:55.048: E/AndroidRuntime(567): at org.ksoap2.transport.HttpTransportSE.call(HttpTransportSE.java:114) 01-22 13:33:55.048: E/AndroidRuntime(567): at com.gmgunderground.test.xmds.WebServiceManager.requiredFiles(WebServiceManager.java:66) 01-22 13:33:55.048: E/AndroidRuntime(567): at com.gmgunderground.test.xmds.XmdsService.TimerSchedulerSupervisor(XmdsService.java:267) 01-22 13:33:55.048: E/AndroidRuntime(567): at com.gmgunderground.test.xmds.XmdsService.access$1(XmdsService.java:248) 01-22 13:33:55.048: E/AndroidRuntime(567): at com.gmgunderground.test.xmds.XmdsService$3.run(XmdsService.java:552) 01-22 13:33:55.048: E/AndroidRuntime(567): at java.util.Timer$TimerImpl.run(Timer.java:284) </code></pre> <p>How can I solve this error? Is there a way to prevent application from closing and return only null? As I can see from logcat the error is inside the KSOAP2 Android Library.</p> <p>Best regards</p> <p>Gian</p>

Guidance
A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
