hi there
i am designing an application using NFC with a Nexus phone. i am starting
from a working sample code, which i purged to have a working template to
begin with
the project compile w/o (compile time) errors.
i am getting the following runtime errors when executing the method
getApplication (see >>>>> below)
the error reported by eclipse LogCat is rather obscure as following

dalvik.system.NativeStart.main(Native Method)
here is the relevant code
public void onCreate(Bundle icicle) {
super.onCreate(icicle);
....
mAdapter = NfcAdapter.getDefaultAdapter(this);
mPendingIntent = PendingIntent.getActivity(this, 0,
new Intent(this,
getClass()).addFlags(Intent.FLAG_ACTIVITY_SINGLE_TOP), 0);
IntentFilter ndef = new
IntentFilter(NfcAdapter.ACTION_TECH_DISCOVERED);
mFilters = new IntentFilter[] {ndef,};
mTechLists = new String[][] { new String[] {
android.nfc.tech.NfcV.class.getName() } };
....
public void onNewIntent(Intent intent) {
Log.i("Foreground dispatch", "Discovered tag with intent: " +
intent);
Tag tagFromIntent = intent.getParcelableExtra(NfcAdapter.EXTRA_TAG);
>>>>> myApplication ma = (myApplication)getApplication();
ma.setCurrentTag(tagFromIntent);
Intent newIntent = new Intent(ecmAppActivity.this,
com.efesys.ecmApp.progEcmActivity.class);
startActivity(newIntent);
return;
}
...
myApplication is just this class
public class myApplication extends Application {
private Tag currentTag;
private byte currentDelay;
private byte currentOverwrite;
private byte[] configuration;
/*
private int nbOfAcquiredTemp;
private double currentTemp;
private float maxTemp;
private float minTemp;
private float avgTemp;
private ArrayList<double[]> arrayTemp ;
private ArrayList<double[]> arrayAxis ;
private boolean dataCorrupted;
private boolean graphDownloadedOnceWithoutError= false;
*/
public byte[] getConfiguration() {
return configuration;
}
public void setConfiguration(byte[] configuration) {
this.configuration = configuration;
return;
}
public byte getCurrentOverwrite() {
return currentOverwrite;
}
public void setCurrentOverwrite(byte currentOverwrite) {
this.currentOverwrite = currentOverwrite;
}
public byte getCurrentDelay() {
return currentDelay;
}
public void setCurrentDelay(byte currentDelay) {
this.currentDelay = currentDelay;
}
public Tag getCurrentTag() {
return currentTag;
}
public void setCurrentTag(Tag currentTag) {
this.currentTag = currentTag;
return;
}
}
