I am just starting out on android development and trying out the HelloAndroid tutorial. I have been stuck for a few days now. Initially, the first time I tried it, everything works perfectly and then I move on the second tutorial everything broke. So I'm trying to go back to the easiest and original tutorial and figure out what is happening.
There are three main file that I edited: HelloAndroid2.java package com.example.HelloAndroid2;
import android.app.Activity;
import android.os.Bundle;
public class HelloAndroid2 extends Activity {
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
}
}
main.xml:
<?xml version="1.0" encoding="utf-8"?>
<TextView xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/textview"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:text="@string/hello"/>
strings.xml:
<?xml version="1.0" encoding="utf-8"?>
<resources>
<string name="hello">Hello World, HelloAndroid2!</string>
<string name="app_name">HelloAndroid2</string>
</resources>
These are all from the tutorial.
When I run it, the console output is:
[2010-07-06 16:37:16 - HelloAndroid2] ------------------------------

So, it just gets stuck at the starting: intent... The emulator shows up with the time, date, and the fac that it is charging. I'm developing on Android 2.2. I try to get some data out of LogCat and these are the last few lines:
07-06 20:37:25.935: INFO/AndroidRuntime(387): NOTE: attach of thread 'Binder Thread #3' failed
07-06 20:37:27.265: INFO/ActivityManager(65): Displayed activity com.example.HelloAndroid2/.HelloAndroid2: 1461 ms (total 1461 ms)

07-06 20:38:10.437: DEBUG/SntpClient(65): request time failed: java.net.SocketException: Address family not supported by protocol
So basically, nothing happen on the emulator and it should say HelloAndroid or something like that. Please help.
