How to make money writing iPhone Apps and Games

Nice website on How to make money writing iPhone Apps and Games by Trey Smith:

http://www.treysmithblog.com/

Basically, in a nutshell.  Trey says that you do not need to be a programmer. How To Create iPhone Apps With No Programming Experience? Just outsource the programming. His techniques teaches you how to find the right programmer as well as all the nitty-gritty details. How to find the right app to develop. Don't choose an app where there are plenty of competitors our there, etc. But to do justice to Trey,  why not just hop over to his site and take a look!

Take a look at one of Trey's impressive revenue source from iPhone apps:

There's also an excellent e-book on How to Create iPhone Apps With No Programming Experience:

Or,  create iPhone, iPad games visually using drag and drop and without any coding background, using Game Salad, a highly popular platform for hobbyist and serious indie developers to create fantastic looking games:

Coursework marks, FYP, etc - away on long vacation

I am away on long holiday and will only be coming back to College in February or March, 2012. Meanwhile, just get your results from College. Please do not contact me directly!

AdMob screenshots

Assuming, I am developing Android apps/games. And testing on Milestone (Droid) and

Galaxy Tab.

This is the cropped ad banner when using 1.5 scaling:

This is the correct ad banner when not using scaling:

Assuming, I am developing Android apps/games on Corona and using Kam's AdMob Hack. Which choice should I use, A, B or C? (See below)

Build crash in Windows - Corona SDK - Solved

Problem solved:

STEP 1:
Uninstall Corona SDK (I'm using Build 505 for Windows).

STEP 2:
I totally removed all traces of JAVA (jdk, updates, jre, everything) using Revo Uninstaller. Then, I re-installed Java JDK1.6.0_21 (the same version I had before the uninstall) from scratch.

STEP 3:
Re-install Corona SDK.

NOTE:

I avoided downloading and installing the latest JDK because it might break my Netbeans and Eclipse, and other Java Apps which I already have on my PC (which had their libraries config set on JDK1.6.0.21). Also note that this solution worked for me because the error was caused by java

path. See screenshot below. If your crash was caused by some other factor, then this might not work for you. Also, I am already subscribed to Corona when I found the solution.

Below is the screenshot of the error I had:

Android: Space Blaster Game

Further Eclipse Fix after updating JDK

You may also need to choose which JRE you wish to use in the Excutable Environment as shown above. Select Windows/Preferences/Java ...

Eclipse fix after updating JDK

If Eclipse fails to start after updating JDK, do this.

Insert these two lines in eclipse.ini file:

-vm

C:\jdk1.6.0_20\jre\bin\client\jvm.dll

eg.

 -startup
plugins/org.eclipse.equinox.launcher_1.0.201.R35x_v20090715.jar
--launcher.library
plugins/org.eclipse.equinox.launcher.win32.win32.x86_1.0.200.v20090519
-product
org.eclipse.epp.package.jee.product
--launcher.XXMaxPermSize
256M
-showsplash
org.eclipse.platform
--launcher.XXMaxPermSize
256m
-vm
C:\jdk1.6.0_20\jre\bin\client\jvm.dll
-vmargs
-Dosgi.requiredJavaVersion=1.5
-Xms40m
-Xmx512m

Then add the path to your new JDK to your PATH environment variable:
C:\Program Files\Java\jdk1.6.0_21\bin; ....

Then delete the java.exe file from:

C:\Windows\System32

Android Keeping Location Overlay in View

Android Location Manager

Download a gpx file and put in any folder, in this case GPX Files folder. Then load it from DDMS Emulator GPX tab.

Below is the main activity file. No xml layout file needed. Run the bottom part of GPX file which is collection of points by clicking on the play button of the DDMS. This simulates GPS tracking.

Android Google Map API programming - Easy Zoom

The above map implementation is easier than the previous post. It uses the built-in zoom (at bottom of screen) capability of Google Map API.

The main Activity class:

 package com.mvez;
import com.google.android.maps.MapActivity;
import com.google.android.maps.MapView;
import android.app.Activity;
import android.os.Bundle;
public class MapViewEasierZoom extends MapActivity {
private MapView mapView;
@Override
protected void onCreate(Bundle savedInstanceState) {
   super.onCreate(savedInstanceState);
   setContentView(R.layout.mapview);
   mapView = (MapView) findViewById(R.id.mapview);
   mapView.setBuiltInZoomControls(true);
}
@Override
protected boolean isLocationDisplayed() {
   return false;
}
@Override
protected boolean isRouteDisplayed() {
   return false;
}
}

The mapview.xml layout. Be sure to substitute your map api key in place of XXXXX:

 <?xml version="1.0" encoding="utf-8"?>
<!-- This file is /res/layout/mapview.xml -->
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical" android:layout_width="fill_parent"
android:layout_height="fill_parent">
<com.google.android.maps.MapView android:id="@+id/mapview"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:clickable="true"
android:apiKey="XXXXXXXXXXXXXXXXXXXXXXXXXX"
/>
</RelativeLayout>

Remember to insert the red-highlighted part above, else the map will fail.

Google Maps Setting

Before you can use MapUI or MapActivity, you will need to add the Google API as shown above.

Right click the project, the select properties, then select Google API. This wil insert Android + Google API.

Prior to that you will have to get Google Map API keys as follows:

keytool -list -keystore "C:\Documents and Settings\YourName\.android\debug.keystore"

Output (Debug key):

Certificate fingerprint (MD5): XX:XX:XX:XX:XX:XX:XX:XX:XX:XX:XX:XX:XX:XX:XX:XX

Getting the release key

keytool -list -keystore "D:\My Documents\Android\eclipse-java-helios-win32\eclipse\keystore_yourname"

Output (Release key):

Certificate fingerprint (MD5): XX:XX:XX:XX:XX:XX:XX:XX:XX:XX:XX:XX:XX:XX:XX:XX

Note that the path will be different on your system.

Then, head on to http://code.google.com/android/maps-api-signup.html to register for

the Map API keys by entering the MD5 keys above.
