Following is my MainActivity.java
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.custom_lock);
startService(new Intent(this, MyService.class));
TextView placexml = (TextView) findViewById(R.id.place1);
if (placexml == null)
System.out.println("placexml");
String place = "work";
//System.out.println("place: "+place);
placexml.setText(place);
boolean isApiRunning = ContextSdk
.isSemusiSensing(getApplicationContext());
if (isApiRunning)
Api.stopContext();
else {
SdkConfig config = new SdkConfig();
config.setPlacesAccuracyLevel(PlacesAccuracyLevel.EAccuracyHigh);
config.setActivityAccuracyLevel(ActivityAccuracyLevel.EAccuracyHigh);
config.setActivityTrackingAllowedState(true);
config.setAnalyticsTrackingAllowedState(true);
config.setDemographicsTrackingAllowedState(true);
config.setPedometerTrackingStateAllowed(true);
config.setPlacesTrackingAllowedState(true);
config.setRuleEngineEventStateAllowed(true);
Api.startContext(getApplicationContext(), config);
}
// reloadRssHandler.postDelayed(relaodRssRunnable, time);
//updateUILayer();
/*
txt1.setOnClickListener(new OnClickListener() {
@Override public void onClick(View arg0) { // TODO Auto-generated
method stub System.out.println("finishing......."); finish();
}
});
*/
}
When I run this program, "placexml" gets printed on console. I don't know, why this is happening. place1 is returning null from xml. Please help.
Change lines
android:name="@+id/place1"
to
android:id="@+id/place1"
You need to set ID instead of name.
