Hi gang, I have two outrageously stupid questions about Android... Eclipse is a nightmare for me code-dumb iOS aficionado. Never could do anything. Will Android Studio be easier? Well... not really. Installation on OS X: OK Importing package: OK Running app: yikes! I don't have an Android device yet, so I tried the emulator. Many trials and errors Finally, Nexus S Android 4.0 doesn't generate errors. But... All I get is a white screen looking like a menu, with a single row featuring an arrow, the icon of my app, and the name HomeScreen. Nothing more. Clicking doesn't do anything. So... two stupid questions: 1. What am I doing wrong? 2. If I decide to buy a very cheap Android device, will it be OK for testing? I've found 2 models available in my country for less than 100 bucks: HUAWEI Ascend Y330 with Android 4.2 Jelly Bean and WIKO Sunset with Android 4.4 Kitkat. Please keep in mind that I've never had an Android device in my hands and pardon my dumbness ;-) Thanks in advance for any tips! Cheers Jack

Hi @fusionch, There are no stupid or dumb questions. I would try a few things. Try a clean and refresh on your project in the studio. If that does not work then go to the bt control panel and copy your config file and paste it in your project config file. I would go with the 4.4. LA

I used the nexus s simulator for my midterm exam and it took literally 10 minutes to load up.I have used a hauwei phone in the past to run bt apps in studio and eclipse, although it was a pretty slow device compared to my galaxy.as long as it's 4.0 and up it should work

Thanks guys... My problem was elsewhere... Anyway LA's advice was good, even if I had already cleaned and refreshed, and copy-pasted config... Xcode basics too ;-) CMCoffee's advice was good too, I tried another emulator and everything's ok... But now I have to dive deep into study, as it's really a different universe! I will sure have more problems and questions later :-) Cheers Jack

Don't forget to spend time looking at LogCat...there is valuable info in there that will tell you exactly what's happening in an RUNNING app. Here's a video showing how it works: https://www.youtube.com/watch?v=ayIR5a51Ohg Mark

Thanks, Mark, I guess I'll need all your tutorials :-) Cheers Jack

You can never go wrong with Mark's tutorials! Also, I often uninstall the App I'm using on the emulator when I get a white screen like you did. Learn how to uninstall Apps on the emulator and you can get more storage and and it makes the emulator run faster. LA

Thanks for the tip! Quitting emulator and studio, relaunching and cleaning is not enough? By the way... All my apps use tabs... Is the new BT package OK for apps with tabs? I tried a tabbed layout and I only get the screen corresponding to the first tab. And when testing I don't see any reference to my tab icons in LogCat... Puzzling! Jack

Everything in Buzztouch is compatible with the new package. The new stuff is literally a new way of packaging everything in the order that Studio wants it...doesn't touch any code at all. Did you include your tab icons in your project? They need to be in res > drawable. And did you link other screens to your additional tabs? Mark

this is irrelevant sort of but Parse works flawlessly on new bt android studio package, just by following parse online instructions. No extra steps needed. Just take out one of the receivers in the manifest I couldn't get the buzztouch.com hosted apps to send push from cp tho, just parses gcm backend

I'm just groping... but yes, I did include the tab icons in res > drawable and I did link other screens! -- Er... what a strange universe! Guess all iOS-regulars are feeling lost at start ;-)

Try dragging them in the project you unzipped instead of android studio

I did! I've seen that Android Studio, when you quit and relaunch, "sees" any file you add, you don't have to drag the files into the software (as in Xcode).

Is the name of the images in all lower case letters?

Also, if you want to see the names of the icon in LogCat use the bt debugger class or log class.in bt_activity_host.java in setupTabs method find this code: if(iconName.length() > 0){ d = BT_fileManager.getDrawableByName(iconName); } Then add this under it: System.out.println ("icon :" + iconName); (Sorry don't remember log methods, works the same though) Edit ------- if you want to use bt method: BT_debugger.showIt(activityName + "icon: )" + iconName);

Sure, and with _ not - (Trial and error... Slowly discovering...) Thanks anyway!

(I'll try the next tip, thanks!)

If you've specified the names of the icon files in your control panel, then there should be some output regarding them in LogCat. And, as Chris mentions, they have to be named using the syntax of no special characters, spaces, or anything crazy like that. It's best to name them all lower case. Mark

I think I messed things up, so I redownloaded package, put all files in the right place with the correct syntax... Found some errors on my side, some errors in the plugins... But... still not OK with tabbed layout! I'm afraid some deprecations in the code are the reason... In BT_activity_host, there are many warnings about deprecations focused on tabs... Have a look at: //remove tabs if we're using them... if(actionBar.getNavigationMode() == ActionBar.NAVIGATION_MODE_TABS){ actionBar.removeAllTabs(); } and: //get title and icon for this tab... String title = BT_strings.getJsonPropertyValue(thisTab.getJsonObject(), "textLabel", ""); Drawable d = null; String iconName = BT_strings.getJsonPropertyValue(thisTab.getJsonObject(), "iconName", ""); if(iconName.length() > 0){ d = BT_fileManager.getDrawableByName(iconName); } Tab tmpTab = actionBar.newTab(); tmpTab.setText(title); tmpTab.setTabListener(this); tmpTab.setTag(t); if(d != null) tmpTab.setIcon(d); actionBar.addTab(tmpTab); } ... and maybe some more? Any idea? Cheers Jack
