I am new to java and android and wanted to see how developing for android works
I started by downloading the SDK FROM HERE
However after I finish making the Hello World project sample given in the website HERE, if I try to run it on the emulator as explained HERE, the emulator screen appears, but nothing seems to happen. I can see the word android on the middle of the screen with some animation happening, but that's it. The website says something about unlocking the emulator, but I have no idea what that means. What I have gathered from reading other posts is that the emulator is supposed to have some kind of slider switch as in real smart phones which should be dragged to unlock it, but I can't see it in my case. Now I have no idea why this is happening or what I should check out in order to fix this. Are there any installation logs or something else that I can check to see what the settings are?
What I have tried till now:
I downloaded the SDK ADT bundle from HERE and just unzipped it. Then looked for eclipse.exe and ran it directly. Is there anything else I should have done prior to this?
When I did it for the first time, I had only JRE installed and not JDK, which I realized after reading THIS POST. So I downloaded JDK from HERE, updated the required environment variables and restarted eclipse, but still it's the same thing.
I looked at the Eclipse isn't talking to the emulator section GIVEN HERE, but all it says is to restart eclipse and the emulator, and it doesn't do anything at all.
Rant:
I can understand if the program had failed to compile when I didn't have JDK , or if the IDE gave any indication at all of a faulty program install, but that isn't the case. Everything seems ok, there are no errors, but it just doesn't do anything. This is the type of thing that makes people pull their hair out, and personally, I think the With a single download, the ADT Bundle includes everything you need to begin developing apps: in the android website is very misleading, especially for complete beginners
Anyway, what should I do to make the tutorial program run on my computer? My computer is a bit old and slow so could that be an issue? My computer is Windows XP SP3 on Intel(R) Pentium(4) 4 CPU 3.20 GHz 3.19GHz 2.50GB RAM, but if that was the case I assume the emulator shouldn't even start up
I had the exact same problem as you when I first got into Android development a week ago. The two things I did are simply
1) Set the usable RAM on your AVD to 768MB
2) When you run your Hello World program in your emulator, give it about 5-10 minutes. Don't touch or click the window at all, just let it load up. Later you can make it persist
3) If your home screen comes up, click and hold the mouse button in the center of the screen, then drag towards the sides and release, this should unlock the device.
Try these steps first, if they don't work then there is likely a problem with your AVD configuration.
