[android-developers] java.lang.NullPointerException and Unknown Source

[thejaswi s]

In my code I am getting this error. I pasted full log cat
java.lang.RuntimeException: Unable to start activity
java.lang.RuntimeException: Unable to start activity ComponentInfo{

My oncreate metode contains following code

public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.registration);

/* To calculate uId in email sending path */
TelephonyManager teleman = (TelephonyManager) getBaseContext()
.getSystemService(Context.TELEPHONY_SERVICE);
sws = new SaWebService();
deviceId = teleman.getDeviceId();
uId = deviceInfo();

re = RegisteredEmail.getInstance(this);
prefs = getApplicationContext().getSharedPreferences("email_id",
MODE_PRIVATE);

btn = (Button) findViewById(R.id.email_submit);
new_reg = (Button) findViewById(R.id.newuser_signup);
new_reg.setOnClickListener(new OnClickListener() {
public void onClick(View v) {
Intent viewIntent = new Intent(
"android.intent.action.VIEW",

Uri.parse("http://panel.strategyanalytics.com/default.aspx?mod=registrationfull";));
startActivity(viewIntent);
}
});

email = (EditText) findViewById(R.id.email);
email.setOnFocusChangeListener(new OnFocusChangeListener() {
public void onFocusChange(View v, boolean hasFocus) {
email.setHint("");
}
});

btn.setOnClickListener(new OnClickListener() {
public void onClick(View arg0) {
email = (EditText) findViewById(R.id.email);
emailStr = email.getText().toString();
new AddTask().execute();
setContentView(R.layout.main);
email.setText("");

}
});
}


Help me out where I am going wrong. Thanks for help in advance.


Thanks,

Thejaswi
