Appcelerator and Android Bug: Invalid “–device-id” value “XYZ” Tips, Tricks and Tutorials 10 JAN 2017

Working in Appcelerator Studio, I was trying to compile and run the Android app that I’m developing on a Lenovo A7600-H tablet hooked up to my Windows 10 laptop via USB.

Developer Options’ USB debugging checkbox was turned on (remember, if it isn’t already showing – and it shouldn’t be – you can open up Developer Options as a Settings menu option by clicking 7 times on the Build Number item tucked away behind the About Phone/Tablet settings menu option), and the USB computer connection was set to MTP media device/files option.

However, the run process kept aborting with the following error message: Invalid “–device-id” value “XYZ” where XYZ was a label associated with the hooked up device.

As it turns out, the problem is actually one of authentication or rather authorization – essentially the device doesn’t trust the PC that it is currently plugged into. So to resolve, I turned off the “USB debugging” setting, clicked on the “Revoke USB debugging authorizations” menu option below that, and then turned USB debugging back on. The tablet asked me if it was okay to allow the computer connection, and after confirming on the device and then returning to Appcelerator Studio to compile and run, the Invalid –device-id issue was gone.

So, worth jotting down for future reference then.

Do You Still Use Your Tablet? My Life 08 MAR 2015

Back in April 2013 I ordered an Android 4.1 Proline Smart AK888-13 9.7″ Dual-Core Tablet from Loot.co.za. Of course, when it arrived I was very excited and played around with it, showed it off, and generally beamed with pleasure.

In the nearly two years since then, Android has gotten much, much better, hardware specs have greatly improved, and you know what – I seriously doubt that I’ll bother replacing my tablet.

As it turns out, owning a tablet seems rather… well… pointless.

Here’s the problems I sit with:

  1. The 10 inch tablet is relatively large, meaning it is not something that is going to go everywhere with you – unlike your phone which you pretty much sleep with.
  2. It’s not really useful for work without a physical keyboard, as onscreen keyboards are relatively slow and painful to type long strings out on. If I add a physical keyboard to it, then I’ll probably be sitting down at a table – which in that case I would much rather be using my far more versatile Windows 7 Fujitsu laptop for the job.
  3. With most major websites now catering for small screen mobile displays, web browsing on my phone is pretty pleasurable – and the phone fits much nicer in my hand than the tablet (plus it’s always on me). So again, why would I bother fetching the tablet to browse the web?
  4. My Android phone is as powerful as my Android tablet, so I tend to play mobile games on my phone if I don’t want to switch the XBOX 360 on. And if I do want to sit down for a proper gaming session – well, then I’ll go and turn the XBOX 360 on.
  5. For watching media, the phone works better because it is smaller, lighter to hold, and if you are watching something up that close, well then screen size tends not to matter all that much anyway!

So that’s five reasons as to why my tablet has pretty much sat next to my bed gathering dust for the last two years. Jess will probably get to play on it pretty soon, and if it breaks – well let’s just say I see no real need to replace it.

In fact, there is only one thing thus far that I have found the tablet to be absolutely awesome for: reading comic books using Komik Reader before going to bed. The screen size more or less matches that of a physical comic book, meaning the two just go hand in hand! (Of course, this is completely negated if I switch to the Comixology app with it’s guided view technology that works perfectly fine on a phone’s small screen.)

The problem is though, if I had a real paper comic book, I’d much rather pick up and read that!

So for me a tablet turns out to be a not such needed device after all, which begs the question – do you still make use of your tablet then?

Android Gaming Update (Part 3) Games | My Reviews 24 JUN 2013

I recently purchased a Proline Smart AK888-13 9.7″ Dual-Core Tablet from Loot.co.za for the low price of R2,099, featuring a 1.6GHz Cortex A9 Dual-Core CPU, a 10 point multi-touch capacitive screen with a resolution of 1024×768 (4:3), 1GB memory backed up by a 16GB NAND memory capacity, and running the fantastic Android 4.1 Jellybean OS. No 3G but obviously Wi-Fi and BlueTooth capable.

In other words, not a high-spec tablet like your Apple iPad or your Samsung Galaxy Tab, but a very serviceable, extremely well priced, Chinese manufactured (Proline simple imports and brands them) mid-range tablet with a nice solid and fashionable design, good handling and the surprising ability to play 3D games rather well.

So with the wonderous Google Play store at my finger tips, this is part 3 of the list of games I find myself currently playing (and enjoying) on my new entertainment device: (You can find Part 1 of the list here and Part 2 of the list here).

dungeon hunter 4 android game

Note that all of these follow the so-called ‘Free-mium’ model, i.e. they are free to download and play, but do feature advertising and do offer additional in-app purchases that allow you to progress through the game faster or gain access to better equipment or abilities. You get what you pay for in the end…

Heroes of Destiny (2013): This action RPG sees you directing a team of upgradeable heroes, each with their own unique strengths and skills, through a fantasy world of woods, towns, forests and dungeons, taking on foes and collecting loot in the process. Their quest: free the Kingdom of Lerona and beyond from the corrupting influence of the mysterious evil known simply as the Darkness. The visuals are slick and the gameplay quite enjoyable, making this a worthy action RPG to spend some of your valuable free time on!

Aces of the Luftwaffe (2013): This smoothly animated, vertically scrolling shoot ‘em up puts you in the seat of an heroic Allied fighter plane, taking on horde after horde of evil Axis fighters. The gameplay is fast and relentless (as expected from this genre), as you frantically dodge bullets and planes that seem to be coming at you from all directions, all the time! Addictive fun that saw me wasting more than just a few hours away on this one!

Drunk Vikings (2013): This is an interesting one, in essence a tower defence game which puts you as a dragon atop your nest which rests on a rocky spire. Unfortunately for you, drunken vikings are rather keen to mess with you and knock your home down, meaning you need to move your fingers fast to flick and toss away the marauding vikings, who seem to be coming at you from angles. Luckily you have some pretty useful powers and potions to help in the struggle, but bear in mind, this is NOT going to be an easy task! Its comical and surprisingly difficult, but I have to be honest, it didn’t hold my attention for very long. That said, it certainly was something a little different, so well worth checking out based on that alone!

Dungeon Hunter 4 (2013): A very polished, slick and visually excellent hack and slash action RPG from the development team over at Gameloft. Dungeon Hunter 4 features a suitably epic storyline (as expected given the high quality of the previous games in the series) and is a superb quality dungeon crawler that will have you killing all types of enemies, building up your stats, and happily collecting loot as you trudge through gloomy environment after gloomy environment. If Diablo style games of sword swinging and spell casting chaos are up your alley, then Dungeon Hunter 4 will certainly not disappoint!

KungFu Rabbit (2013): This enjoyable platformer places you as the only surviving rabbit who manages to escape the temple of rabbits during the Universal Evil’s deadly purge. Now it is up to you to take revenge, as you jump from roof to roof, slide gracefully along walls, sneak up on your enemies and rip them to shreds! It’s cute, features a well implemented platforming control scheme, and has enough logic-draining puzzles to make for an entertaining time waster.

Android Gaming Update (Part 2) Games | My Reviews 18 JUN 2013

I recently purchased a Proline Smart AK888-13 9.7″ Dual-Core Tablet from Loot.co.za for the low price of R2,099, featuring a 1.6GHz Cortex A9 Dual-Core CPU, a 10 point multi-touch capacitive screen with a resolution of 1024×768 (4:3), 1GB memory backed up by a 16GB NAND memory capacity, and running the fantastic Android 4.1 Jellybean OS.

Angry Birds Star Wars (2013): By now pretty much everyone on the planet has been exposed to the addictive and enjoyable casual gaming experience that is Angry Birds, basically a game that allows you to catapult different types of birds (each with their own special abilities) at some nasty pigs and the structures that they inhabit. Well Angry Birds Star Wars is the next evolution of the title and marries the gameplay of the first game and the follow up Angry Birds Space into one, heavily Star Wars referenced game. To be honest, unless you’re a Star Wars fan then you’re not really going to enjoy this one, as a lot of the charm is lost in space, and I must admit, the Jedi powered and laser pistol equipped birds seemed to reduce the difficulty of the game, meaning that I didn’t quite get as much enjoyment out of it like I got out of the first.

Candy Crush Saga (2012): In the same vein as Bejeweled and the countless variants before and after that, Candy Crush Saga is a surprisingly enjoyable and addictive puzzle game that sees you switching and matching board after board of brightly coloured candies, trying desperately to unlock the powers of a long string match in the hopes of beating whatever winning condition needs to be met before your allotted moves run out. Very addictive and I found myself particularly enjoying this one!

Frontline Commando: D-Day (2013): Frontline Commando is an impressive third person shooter that is set in World War II and sees you controlling a commando taking on the D-Day battle of Normandy, making the beach landing, clearing the trenches and ultimately taking the fight right up to the Axis soldiers. The 3D graphics and sound are fantastic if you consider that this is a mobile game, and this third person shooter makes for a very enjoyable break from the more simpler games currently populating the mobile gaming world.

Dragon Slayer (2013): Dragon Slayer is another polished hit from the excellent mobile game producer Glu Mobile, and this around you are tasked with travelling around a fantasy world and slaying troublesome, mountainous dragons, reptiles and wyverns! Basically the game is made up of a series of battles, where your character model faces off against a fearsome creature and you have to dodge and time your attacks, learning the beast’s unique attack pattern in order to defeat it before your health bar can run out. Gorgeous 3D graphics and action-packed gameplay makes this quite the enjoyable action title to pick up!

Android Gaming Update (Part 1) Games | My Reviews 16 MAY 2013

An unexpected but rather nice bonus I might add.

So with the wonderous Google Play store at my finger tips, this is the list of games I find myself currently playing (and enjoying) on my new entertainment device:

Note that all of these follow the so-called ‘Free-mium’ model, i.e. they are free to download and play, but do feature advertising and do offer additional in-app purchases that allow you to progress through the game faster or gain access to better equipment or abilities. You get what you pay for in the end…

Temple Run 2 (2013): The follow-up to the original popular and successful Temple Run endless running game, and is basically a fun time waster which sees you running through an endless maze collecting coins and power-ups, all while dodging, jumping over gaps and sliding under obstacles, trying to stay one step ahead of a hairy bunch of ape monsters following just one step behind! Now I’m not a huge fan of endless running games so this didn’t hold my attention for all that long, but it is definitely worth a look thanks to great 3D graphics, presentation and implementation. Plus, it’s always nice to beat a buddy’s run distance…

Nun Attack (2013): A particularly enjoyable and creative game, Nun Attack puts you in control of a customizable squad of nuns who are attempting to bring down one of their own and need to navigate their way through a number of spooky levels featuring all manner of skeletons, goblins and werewolves, not to mention menacing and explosive portals. Each nun comes with a special attack ability and a number of customizable weapons, meaning it is up to you to come up with the combination that works best for you in progressing forward. Clever mixing between modes of play and a fun cartoon style makes for an entertaining romp that is certainly worth picking up if you have some time to waste or just like the idea of nuns with guns.

Monster Shooter (2013): A dual-stick shooter that sees cutely animated monsters do battle as your heavily (and customizable) armed monster tackles wave after wave of octopus aliens and other alien creepies, all from an engaging top down view. Good graphics, fun gameplay and a surprising large amount of alien blood and gore makes for quite the entertaining mobile gaming time waster.
Related Link: https://play.google.com/store/apps/details?id=com.gamelion.MonsterShooter

League of Heroes (2013): A bit too on the cutesy side for me to be honest, but basically this is your run of the mill top down action RPG that sees you adventuring around and hitting cute monsters, foes and bosses, all while leveling up your stats, gear, and abilities. A polished package for sure, but like I said, a little bit too cutesy for my liking.
Related Link: https://play.google.com/store/apps/details?id=com.gamelion.loh

Jetpack Joyride (2012): An endless runner type game which sees you trying to constantly beat your distance covered with every run, the hook here being that you’re a guy piloting a machine gun jetpack, meaning that there is plenty of controlled jumping, flying and dodging of obstacles to have. To spice things up, special vehicle pickups are also thrown into the mix, as well as a lucky slots machine and some nifty gadgets to upgrade your abilities. A well put together package which is polished, implements its mechanics well and is fairly enjoyable to play. Oh, and the cartoony art is pretty fun too.

Guns ‘n Glory WW2 (2013): Basically a tower defense type game which sees you commanding either an Allied or a Axis force from a top down view, desperately defending your base from wave after wave of approaching enemy. It is a well implemented, good looking (if a little cartoony) game that feature a nice mix of units and is surprisingly enjoyable to play.

Review: Aces of the Luftwaffe (2013) Games | My Reviews 02 MAY 2013

Now armed with an Android powered 10 inch tablet all of my own, one of the first games I installed turned out to be the thoroughly entertaining Aces of the Luftwaffe, from developer HandyGames.

aces of the luftwaffe 1

If you remember the awesome coin-swallowing arcade game from the ’80s, 1942, then you know exactly what lies in store for you from the enjoyable Aces of the Luftwaffe, a vertically scrolling shoot ’em up that puts you in the seat of an heroic Allied fighter plane, taking on horde after horde of evil Axis fighters.

As expected from this genre, the pace is relentless and the action non-stop, not to mention the insane difficulty that comes with the territory of a screen filled with slow moving projectile bullets! Of course the usual power drops of wingmen, scatter shots and machine gun are there to aid you, as well as a clever little ‘super’ which amounts to a cavalry rush that obliterates everything on screen.

The game is released as a free to play and is ad supported, though as expected one can make the purchase to remove the adverts. Leveling up of various aspects of your plane is possible, and in the same breadth, you can always choose to speed up this process through in-app purchases.

Fun graphics, a good soundtrack and a well written game with a smooth handling interface means that Aces of the Luftwaffe is certainly one of those recommended titles to install if you’ve got some free space on your tablet!

The High Price of Standalone Scanners Personal Musings 16 APR 2010

I’ve decided that I need to lay my hands on a scanner.

The reason is pretty simple. A while back I moved to the straight digital path after laying my hands on a drawing tablet to use at home for my own purposes. Doing everything via the digital route definitely has its advantages in terms of speed for time to completion, but in the process I’ve noticed that what I produce is well… diminished in quality to say the least.

The problem of course lies rooted in a couple of factors, so I’ll try and lay them out here. First off is the whole breaking of the visual from the hand movements thing that comes with using a tablet, followed by the fair inability to naturally change hand orientation at will. Now of course, these could be circumvented by using a tablet system like an Apple iPad or even shelling out for a Wacom Cintiq product, but seeing as this is completely a free time hobby which I don’t pay all that much attention to, shelling out that kind of cash just doesn’t seem justifiable to me or my wife! After those two biggies, next comes the feel of the whole affair (nothing really beats pencil on paper), as well as to an extent the joy of seeing your work right in front of you, no matter where you may be.

Sure there are some great software and hardware solutions to tackle all of these, but like I said, I’m not really willing to spend a lot of money on this hobby of mine, so those are pretty much out of the question.

So the solution is of course to go back to pencil and paper, sketch out the drawing and then scan it in, before finally switching to the good old tablet to handle “inking”, colouring and of course lettering.

A slower process, but one which should definitely make the resulting pencils look a whole lot less stiff.

But here’s my bugbear then. Why in the world are standalone scanners so expensive?!? They’ve definitely gone up in price since the last time I purchased one (which was way back when admittedly), and are actually more expensive to buy in the standalone format than as part of an all-in-one scanner/fax/printer combo!

I’ve already got a printer, I don’t need another. All I want is a scanner you know…
