Hi all,
I'm trying to create a simple example with 2 activities:
1. A simple Welcome (the MAIN): A simple welcome screen with a
button.
2. A MapActivity (class=Quester) which simply displays a map.
a) The MapActivity (Quester) works by itself when the manifest gives
it the MAIN, like this
<activity android:name=".Quester" android:label="@string/
app_name">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category
android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
b) Pressing the button on the welcome screen /tries/ to invoke an
Intent to start the quester activity
but it throws an ActivityNotFoundException (details below); here's the
Intent code:
private void checkLogin(QLogin loginActivity, String userId, String
passwd)
{ // right now a stub always returning true:
boolean authOk = authenticateUser(userId, passwd);
if (!authOk){
Toast.makeText(this, "Unknown userid/password combo",
Toast.LENGTH_SHORT).show();
} else {
Toast.makeText(this, "Trying to move to Quester Map",
Toast.LENGTH_SHORT).show();
Intent questerMapIntent = new Intent(".Quester.VIEW");
startActivity(questerMapIntent);
}
}
c) The complete manifest is:
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android";
package="com.herenow.android.quester">
<application android:icon="@drawable/icon" android:label="@string/
app_name">
<activity android:name=".QLogin" android:label="@string/
app_name">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category
android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<activity android:name=".Quester" android:label="@string/
app_name">
<intent-filter>
<action android:name="android.intent.action.VIEW" />
</intent-filter>
</activity>
<uses-library android:name="com.google.android.maps" />
</application>
<uses-permission android:name="android.permission.INTERNET" />
</manifest>
d) The error output in LogCat is the following:

I've tried the following versions for the Intent descriptor (keeping
them coordinated in the code and the manifest):
Quester.VIEW
.Quester.VIEW
com.herenow.android.quester.Quester.VIEW
and
.Quester.VIEW in manifest and Quester.VIEW in code .
So I'm missing one or more points here.
Can anyone help me out?
Many thanks in advance,
Ken
