1,319 PointsCode check, Android Login/Main Activity
Hi I am developing my own app using the tutorials here.
This code, like in the tutorial, is trying to bypass the Main Activity and go to Login; but I get an error that the application stops every time I run it, implying something is wrong with the code; I will continue to investigate but wanted to ask for help too...thanks so much!
public class MidwifeActivity extends Activity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_midwife);
//start with Login Activity
Intent intent = new Intent(this, LoginActivty.class);
//login is new task, clear former task from history (main)
intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TASK);
startActivity(intent);
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.menu_main, menu);
return true;
}
@Override
public boolean onOptionsItemSelected(MenuItem item) {
// Handle action bar item clicks here. The action bar will
// automatically handle clicks on the Home/Up button, so long
// as you specify a parent activity in AndroidManifest.xml.
int id = item.getItemId();
//noinspection SimplifiableIfStatement
if (id == R.id.action_settings) {
return true;
}
return super.onOptionsItemSelected(item);
}
}

Apart from the pop-up in the emulator that unhelpfully tells you that the application stopped, can you show us the errors you will be getting in the Logcat part of Android Studio. In there, we may be able to identify precisely what's wrong and, more importantly, where!
Shout if you need a hand with that. Either on here or tweet me @OnlySteveH - I'll hear you!

1,319 PointsHi, Thanks for your help. I just thought of LogCat after I posted (I developed an app using PhoneGap and used Eclipse..PhoneGap is probably not even around anymore).
Anyway, Logcat is stating this:
03-11 15:29:12.830 1367-1367/android.bignerdranch.com.mobilemidwife E/AndroidRuntime﹕ FATAL EXCEPTION: main Process: android.bignerdranch.com.mobilemidwife, PID: 1367 java.lang.RuntimeException: Unable to start activity ComponentInfo{android.bignerdranch.com.mobilemidwife/android.bignerdranch.com.mobilemidwife.LoginActivty}:
Which leads me to think it's something to do with the LoginActivity?
Here that is (below); I will continue to troubleshoot; fairly new to this, though I read through the BigNerdRanch Guide to Android.
And, yes, I am making an app for midwives...
Thanks for any help you can provide

57,712 PointsI'll edit that to make the code a little clearer then have a look through to see what might be the problem.
Steve.

57,712 PointsIs there code anywhere that is expecting LoginActivty
to be spelt "correctly" - that might cause an issue.
And what is the onClickListener
in onCreate
doing? The intent
seems to make it stay put.
(I'll keep editing/adding as I think of stuff!)
Michael Cabus
1,319 PointsHi I updated the code you mentioned; onClickListener is supposed to be:
mRegisterTextView = (TextView)findViewById(R.id.register);
mRegisterTextView.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
Intent intent = new Intent(LoginActivity.this, RegisterActivity.class);
startActivity(intent);
}
});
I'm moving on to trying Parser, and need to fix some things there; but will try to run the app again.
Thanks so much for your help
Michael
Steve Hunter
57,712 PointsAre you using Parse.com for your back-end?
Michael Cabus
1,319 PointsHi, Yes I am...but I was getting this error before I started using Parse.
This is for a grad design thesis project...I appreciate your help!

57,712 PointsWhat error is persisting still? Did amending that code not fix the activity showing up?
Steve.
Michael Cabus
1,319 Pointsthe error still persists.
Not sure why
Thanks for your help!
Michael
Steve Hunter
57,712 PointsCan you put your code into a Github repo - I can then have a look through it and see what might be missing.
Cheers,
Steve.
