Changed things around and now have a new error "******************* Error ******************************** W/System.err( 621): android.content.ActivityNotFoundException: Unable to find explicit activity class {com.thomas.needham/.HelloWorld}; have you declared this activity in your AndroidManifest.xml?"
It is unclear which manifest the error is referencing as the log seems to indicate "Displayed activity com.thomas.needham/.HelloWorld" for intent code and the HelloWorld code. Here's some revised code ------------ Hello World ------------------------------------------ package com.thomas.needham; import android.app.Activity; import android.os.Bundle; import android.widget.TextView; public class HelloWorld extends Activity { /** Called when the activity is first created. */ @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); TextView tv = new TextView(this); tv.setText("Hello, Android Once More!!"); setContentView(tv); } } ----------------------Hello World Manifest ------------------------------------ <?xml version="1.0" encoding="utf-8"?> <manifest xmlns:android="http://schemas.android.com/apk/res/android" package="com.thomas.needham" android:versionCode="1" android:versionName="1.0" > <uses-sdk android:minSdkVersion="7" /> <application android:icon="@drawable/ic_launcher" android:label="@string/app_name" > <activity android:name=".HelloWorld" android:label="@string/app_name" > <intent-filter> <action android:name="com.thomas.needham.HelloWorld" /> </intent-filter> <intent-filter> <action android:name="android.intent.action.MAIN" /> <category android:name="android.intent.category.LAUNCHER" /> </intent-filter> </activity> </application> </manifest> ------------- Revised Intent Program ----------------------------- package com.needham.NLauncher; import android.app.Activity; import android.content.ActivityNotFoundException; import android.content.Intent; import android.os.Bundle; import android.util.Log; public class SubLauncher extends Activity { /** Called when the activity is first created. */ private static final String TAG = "NSubLauncher1"; public void onCreate(Bundle savedInstanceState) { Intent helloworldIntent = new Intent(); helloworldIntent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK); helloworldIntent.setClassName("com.thomas.needham", ".HelloWorld"); try { Log.d(TAG, "HelloworldIntent: "+ helloworldIntent ); startActivity(helloworldIntent); } catch (ActivityNotFoundException e) { e.printStackTrace(); } ------------------------- NLauncher manifest <?xml version="1.0" encoding="utf-8"?> <manifest xmlns:android="http://schemas.android.com/apk/res/android" package="com.needham.NLauncher" android:versionCode="1" android:versionName="1.0" > <uses-sdk android:minSdkVersion="7" /> <uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED" /> <application android:icon="@drawable/ic_launcher" android:label="@string/app_name" android:debuggable="true"> <activity android:name=".SubLauncher" android:label="@string/app_name" > <intent-filter> <action android:name="android.intent.action.MAIN" /> <category android:name="android.intent.category.LAUNCHER" /> </intent-filter> </activity> <!-- android.intent.action.BOOT_COMPLETED --> <receiver android:name="com.needham.NLauncher.NLauncher" > <intent-filter> <action android:name="android.intent.action.BOOT_COMPLETED" /> </intent-filter> <intent-filter> <action android:name=".HelloWorld.LAUNCH_APP" /> <!-- <action android:name="com.needham.NLauncher.LAUNCH_APP" /> --> </intent-filter> </receiver> </application> </manifest> ------------------------------Logcat -------------------------------- D/dalvikvm( 97): GC freed 123 objects / 5072 bytes in 80ms ********************* HelloWord starts ******************** I/ActivityManager( 51): Starting activity: Intent { act=android.intent.action.MAIN cat=[android.intent.category.LAUNCHER] flg=0x10200000 cmp=com.thomas.needham/.HelloWorld } I/ActivityManager( 51): Displayed activity com.thomas.needham/.HelloWorld: 488 ms (total 3909291 ms) W/KeyCharacterMap( 501): No keyboard for id 0 W/KeyCharacterMap( 501): Using default keymap: /system/usr/keychars/ qwerty.kcm.bin W/KeyCharacterMap( 97): No keyboard for id 0 W/KeyCharacterMap( 97): Using default keymap: /system/usr/keychars/ qwerty.kcm.bin D/dalvikvm( 501): GC freed 281 objects / 16824 bytes in 154ms *************** NLauncher starts **************************** I/ActivityManager( 51): Starting activity: Intent { act=android.intent.action.MAIN cat=[android.intent.category.LAUNCHER] flg=0x10200000 cmp=com.needham.NLauncher/.SubLauncher } I/ActivityManager( 51): Start proc com.needham.NLauncher for activity com.needham.NLauncher/.SubLauncher: pid=621 uid=10035 gids={} D/ddm-heap( 621): Got feature list request D/NSubLauncher1( 621): HelloworldIntent: Intent { flg=0x10000000 cmp=com.thomas.needham/.HelloWorld } I/ActivityManager( 51): Starting activity: Intent { flg=0x10000000 cmp=com.thomas.needham/.HelloWorld } ******************* Error ******************************** W/System.err( 621): android.content.ActivityNotFoundException: Unable to find explicit activity class {com.thomas.needham/.HelloWorld}; have you declared this activity in your AndroidManifest.xml?
