Hi Victor. That’s a lot of questions and @JonPM’s advice is sound. Yes, Android is different, but Corona SDK tries to make it so your code doesn’t have to be considerably different.
Android emulator is it the same as saying Corona Simulator?
No. Android emulator is like saying the Xcode simulator. You generally do not need the Android emulator.
I though you can do that in corona simulator, there is a drop down
menu that says “view as iPhone” view as Android, view as many things.
Corona SDK has several “skins” that provide the right screen dimensions and info to make your app think it’s running on that particular device. If you’re testing for Android, you want to pick one of the devices that represents an Android device you want to run on. I personally like the Galaxy S3 skin or the Kindle Fire skin to start with. You will eventually want to see how your app looks on all of them. What you will find with Android is that there are many different devices with different screens and it’s very hard to make your app fit all of them.
Android is the same as saying Apple?
No. Android is like saying iOS. Google is like saying Apple.
if I have an iPad I go to the App store, if I have an android tablet i got where…?
https://play.google.com/store or the Google Play app on the device.
"Create an AVD for each Android version you want to test on." – What is an AVD?
"select GPU Emulation and set it to YES." – What’s GPU?
This is stuff you generally should not need to mess with. GPU means Graphics Processing Unit. AVD = Android Virtual Device.
"using the ADB tool" – What’s ADB?
ADB stands for Android Debug Bridge. It is a set of tools that lets you instal/uninstall your apps on your device. It also lets you examine the console log on the device looking for device errors. This is something that you will need to have installed. It runs from the Terminal command window, so you will need to know how to use the command line.
If I want to sale it on the Android, do I have to make a new app with pictures of the correct size of the android?
Yes.
There are many sizes for android tablets, how many?
Too many to count.
which one will be similar to the iPad?
Actually none. The iPad is kind of unique in it’s close to square shape. Most Android tablets are more like HD TV’s in shape, more in common with the iPhone 5 in shape.
Does my code in corona will be the same for android?
About 98%. There will be somethings you have to do different for android. You may need sounds in a different format. Most Android users will want their soft buttons supported, so you will have to add code to support the back button, etc.
Please let me know what I have to do to have my app for sale in Android.
This question is too broad to answer here. Start by googling how to be an Android developer. Read out Android build guide.
