Finally found the cat and sound downloads. Not hard and pretty easy to execute. Cant wait to get an android attached
This course will become read-only in the near future. Tell us at community.p2pu.org if that is a problem.
Remember the Hello Purr video in the first task? How about going through it step by step until you have the app working on your device?
Here it is again so that you can follow along:
Textual tutorials are also available, with instructions on how to use a real device or the emulator:
If you have a phone you can follow this tutorial.
If you want to use the emulator please follow this other tutorial.
To finish the task could you leave a tip for other App Inventor explorers about how you solved any problems you might have encountered?
We would also like to know if you have a preference for the video tutorial or the textual ones so that we can tune in resources in the future. Please leave us a message in the comments!
just in case someone else is wondering, the pic and sound are linked in the tutorial: http://appinventor.mit.edu/explore/content/hellopurr-phone-part-1.html
Ok, i wish it solved before i mastered this android app dev :))
Btw, i successfully followed the first version of tutorial which using android cell phone, the cat miauw perfectly. But i fail with the emulator version. Somehow the emulator always failed to connect.
First it loaded like a phone without simcard, so sluggish (is it normal?), but never scan its SD Card, also the app inventor could not detect it. So i closed it and reload, then it stays black forever.
I wonder what is the minimal hardware requirement to play the emulator, it looks good but so sluggish, how fast the CPU it required to play smoothly?
Btw, i still on HP mini netbook :)
I'm using Linux Mint (Ubuntu based dist.) and, when I was trying to open the Blocks Editor, the browser asked to me where to find the AppInventor command...
Finally I discovered I had to install a deb package for the AppInventor in Linux, here is the package:
I appear to be entirely unable to open the Blocks editor; I've downloaded the file 'AppInventorForAndroidCodeblocks.JNLP' and opened it, or tried to. When I double-clicked on the file, it brought up the Java logo briefly, then changed to a window titled 'Starting application...', which has been sitting there unchanged for twenty-seven minutes. Attempting to open the Blocks editor prompts me to download another copy of the file.
Actually downloading a new copy of the file accomplished nothing; half an hour into the second attempt, the website promted me to ask if I wanted to continue waiting for the blocks editor to open.
any chance you are using Java7? Also would be helpful to know what operating system are you working on. The Java logo that pops up at first should tell you which version it is (probably 6 or 7). There are some problems with 7 at the moment, so if you could install Java 6 instead, that should fix the problem. Let us know how it goes!
I did the task, and I liked the combination of video and text tutorials.
I have one doubt. When I installed the .apk file of the app on the phone, it ask me for permissions as access to internet and some else.
Is there any way to select the permissions an app has?
I think that, for example, is not necessary to give so many permissions to the Hellow Purr app.
as far as I know the permissions are the same for all apps, so anything that you can do with App Inventor has to be made available. You are right in thinking that no internet permissions should be needed for certain apps, but it's one of the trade offs that has to be made when developing this kind of software.
