[android-developers] Android Studio: MotionEvent - touch tracking
Hi, I'm new to Java and Android Studio but handling it quite well because of my years of programming with python (basic concepts carry from language to language). I have a practice project set up and the only propose of this project is for me to learn how to do things the java/android studio way, logic wise. So logically, the last python based api I used, there was a way to issue your own ID to touches and keep track of those touches; therefore you knew if a touch still existed or not. That's where I am right now. I know how to get the touch ID and then get the Index that holds the touch data. Basically I'm using a For Loop on the motion event to process all touches to the screen. Here's the thing Lets say I have 10 touches to process and what I do in a loop is basically collect the info of the touches and store them in a hashtable, so I can then later process all the touches in the hashtable. So as I pull a touch data from the hashtable to process, I want to first check to see if the touch still exits. I'm guessing once a touch enters the "UP" state, it goes out of scope after that because a touch is over after release. Sure I can just check the "Action" to see if it's equal to "UP" but if the touch doesn't exits anymore, that would raise and exception...right? What I thought about doing was, calling "getPointerCount" again, looping through and getting the IDs again and see if the ID of a touch in my hashtable still exits in the MotionEvent and if the ID exists and the "Action" is still equal to "DOWN", then process the touch. Otherwise, if the ID does not exists or the "ACTION" is equal to "UP", do a release button event if needed or just delete the touch from my hashtable because it doesn't exits anymore. I can't help but get the feeling of redundancy though when considering that approach. Is there a way or method I don't know about that allows you to check if a touch still exits before you process actions relating to it? I was thinking just now Well, kind of guessing that, if you have five touches that hit the screen and one of the touches triggers the opening of a menu and that button had higher priority over the other four touches, you could simply ignore the other for touches for that frame and open the menu and in the next frame of the app, if the other four touches are still down, you can deal with them then accoring to their priority. But then again, the touch could still exists in the next frame but the "Action" may be "UP" or "MOVE" instead of down, thus allowing one to write code for a release or move event. With this thought, storing touch data in a hashtable is really not needed then, granted a touch this is on action "UP" will go out of scope in the very next frame (I'm guessing). ..hum.. Maybe I'm just over thinking it. Forgive any "typos", eyes are that super any more. -- You received this message because you are subscribed to the Google Groups "Android Developers" group.

[android-developers] Why is Android so laggy using volume control
I notice that on my phone and Android TV, if I use the volume, everything gets very laggy. Sometimes the volume control doesn't even work right away depending on the app I'm using. It actually seemed to have worsened when I upgraded to Nougat. -- You received this message because you are subscribed to the Google Groups "Android Developers" group.

[android-developers] Any recommendations on how to get transaction-like functionality from in-memory objects?
Hello all, My first post here, so I hope this is not off-topic. I am developing an app in which I am discovering that I need to get the equivalent functionality of database transactions out of in-memory objects. Now some of those objects are backed by a database, but some are non-persistent data that still need to be incorporated into the transactions. An example would be a transaction in which a series of database-backed objects have values change based on the UI state, and the UI state has to then change to reflect those changes - but at any point along the way, the changes being performed can be "denied" and force a rollback of the entire transaction. This is .. not quite easy, but at least easy to understand if everything were backed by the database. But does Android provide any way to get similar transactional functionality out of non-database objects? For example, does Android include the Java Transaction API and an implementation of a Transaction Manager for that API?

[android-developers] Re: Adding virtual device on Emulator.
By virtual device do you mean an extra virtual network device? Assuming you're using the ARM emulator, this can be done by passing extra options to qemu. I'm going to also assume (1) you are running Linux (Mac I believe is okay, too) as I do not know how to do this on Windows; and (2) you have tunctl (on Ubuntu, this can be installed with sudo apt-get install uml-utilities). You can create a TUN/TAP device with: sudo tunctl -u username -t tap0 You can install the TUN/TAP device on the emulator with: emulator -qemu -net nic -net user -net nic -net tap,ifname=tap0,script=no,downscript=no I have found the script=no and downscript=no options to be useful for avoiding errors when the emulator shuts down. You can confirm the TUN/TAP device is running with: adb shell netcfg You should see something like this: lo UP 127.0.0.1/8 0x0049 00:00:00:00:00:00 eth0 UP 10.0.2.15/24 0x1043 52:54:00:12:34:56 eth1 DOWN 0.0.0.0/0 0x1002 52:54:00:12:34:57 tunl0DOWN 0.0.0.0/0 0x0080 00:00:00:00:00:00 gre0 DOWN 0.0.0.0/0 0x0080 00:00:00:00:00:00 Notice the eth1 device; this corresponds to tap0 that you just created. To confirm, on the emulator run: ifconfig eth1 up 10.11.12.2 netmask 255.255.255.0 On the host, open up a new terminal window and run: sudo ifconfig tap0 up 10.11.12.1 netmask 255.255.255.0 sudo tcpdump -n icmp -v -i tap0 Finally, on the emulator run: route add default gw 10.11.12.1 dev eth1 ping -c 5 10.11.12.1 You should get output similar to: 09:58:13.187475 IP (tos 0x0, ttl 64, id 0, offset 0, flags [DF], proto ICMP (1), length 84) 10.11.12.2 10.11.12.1: ICMP echo request, id 26881, seq 1, length 64 09:58:13.187489 IP (tos 0x0, ttl 64, id 35773, offset 0, flags [none], proto ICMP (1), length 84) 10.11.12.1 10.11.12.2: ICMP echo reply, id 26881, seq 1, length 64 09:58:14.190013 IP (tos 0x0, ttl 64, id 0, offset 0, flags [DF], proto ICMP (1), length 84) 10.11.12.2 10.11.12.1: ICMP echo request, id 26881, seq 2, length 64 09:58:14.190028 IP (tos 0x0, ttl 64, id 35774, offset 0, flags [none], proto ICMP (1), length 84) 10.11.12.1 10.11.12.2: ICMP echo reply, id 26881, seq 2, length 64 09:58:15.192087 IP (tos 0x0, ttl 64, id 0, offset 0, flags [DF], proto ICMP (1), length 84) 10.11.12.2 10.11.12.1: ICMP echo request, id 26881, seq 3, length 64 09:58:15.192103 IP (tos 0x0, ttl 64, id 35775, offset 0, flags [none], proto ICMP (1), length 84) 10.11.12.1 10.11.12.2: ICMP echo reply, id 26881, seq 3, length 64 09:58:16.194919 IP (tos 0x0, ttl 64, id 0, offset 0, flags [DF], proto ICMP (1), length 84) 10.11.12.2 10.11.12.1: ICMP echo request, id 26881, seq 4, length 64 09:58:16.194935 IP (tos 0x0, ttl 64, id 35776, offset 0, flags [none], proto ICMP (1), length 84) 10.11.12.1 10.11.12.2: ICMP echo reply, id 26881, seq 4, length 64 09:58:17.196961 IP (tos 0x0, ttl 64, id 0, offset 0, flags [DF], proto ICMP (1), length 84) 10.11.12.2 10.11.12.1: ICMP echo request, id 26881, seq 5, length 64 09:58:17.196977 IP (tos 0x0, ttl 64, id 35777, offset 0, flags [none], proto ICMP (1), length 84) 10.11.12.1 10.11.12.2: ICMP echo reply, id 26881, seq 5, length 64 HTH, Eric On Wednesday, 29 August 2012 20:12:48 UTC-4, MW choi wrote: Hi All.

I have just joined the Android World and am lovn it, however having a bit of trouble with some of the tutorials, in particular the Hello Tab Widget one.

[android-developers] Re: Licensing on Formerly Paid Apps
I can't say for 100%, but my initial thought is: No. AFAIK, when you convert your paid app to a free app and a user then downloads it, the licensing service responds in the exact same way as if the user bought it (i.e. bought it for $0.00). So, I think the only way around your problem is implementing something on a backend server or within your app to keep track of users that paid for the app. That is, release an update a couple weeks prior to making your app free which stores the information you need to remember that it was paid for, then bring the price down to free.

[android-developers] Re: Progress circle (NOT indeterminate!)
But, if you're looking to make a wheel progress bar instead of a horizontal progress bar, then you'll have to make a custom view. It's actually not too hard, and can be easily done by extending the progress bar class, and handling the onDraw methods. My suggestion would be to first draw a circle with your desired empty progress bar color, then draw an arc over top of the same circle in your desired completed color. I'm not aware of any open source projects which give you a progress bar in wheel form. Nick -- You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] Re: Progress circle (NOT indeterminate!)
Here's what you can do: Extend the AbsSeekBar classhttp://developer.android.com/reference/android/widget/AbsSeekBar.html, and implement the onDraw method to your liking. You can capture the height and width of your custom view by capturing those values in the onSizeChanged method. By drawing your circle programatically you can easily make a progress circle that looks good at all resolutions. Also, you don't have to worry about different device resolutions, since you just need to control the size of the view in the layout. Or, you could extend the ProgressBar class and do the same thing.

[android-developers] Re: Screen refreshing
If fact, I do want the UI to be locked while the proccess is working Are you sure you want the main thread blocked? This could cause the Application Not Responding error to pop up during your lengthy process. And users tend to get very confused when their phones become unresponsive. On other platforms, there is some kind of DoEvents() or DoPendingEvents() functions which allow UI threads to proccess pending messages before continuing with the execution. There is some way of doing this in Android? Not that I'm aware of. But you should really consider putting your lengthy process in its own thread. An AsyncTask seems like it'd work well for you here. You can even update your text view in the onPreExecute method, and then notify the user of completion in the onPostExecute method.

[android-developers] Re: LVL Retry Count
I use the default implementation of the Server Managed Policy (read about it herehttp://developer.android.com/guide/publishing/licensing.html#ServerManagedPolicy) for a paid version of my app, and haven't had any problems of note. I haven't had any complaints about false-negatives, or the like -- however, this *doesn't* mean that it doesn't happen, it just means that if it does, then nobody has complained about it to me. As for you concerns: What problems with the grace period are you referring to? The grace period will actually help you out if the case of Retry responses from the server. As for the licensing implementation with no network access, you shouldn't worry too much about that either. Normally, you get about 10 retries before the 503 error occurs. However, if the user has already checked the license with a Server Managed Policy, then the license is cached on the phone for a period of time. So, if the user starts the app up while their device is in Airplane mode (let's say 10 hours into a 12 hour cross-oceanic flight), then the cached license could still give the user a valid response -- even with no network access. This all depends on the VT extra from the initial license response. I'm not sure what a typical value is, but I know it last at least several hours, if not a day or more (if you wanted you could check out the value yourself by setting a breakpoint in the default implementation). Now, if the user *hasn't ever* received a valid license check, then it will fail without network connection. At which point, in my app, I ask the user to check for network connectivity and retry. Something to note: I haven't verified this with anyone on the Android dev team, but I'm pretty sure that once you release your application with LVL enabled on your phone *and* you don't buy your own app (i.e. you have the release version installed on your device, but haven't actually bought it through the market), then the VT extra in the licensing response is not a date that a typical user will receive. That is, I've found that without actually purchasing the app, the licensing server gives me a validity time which basically disables any valid cached response. Again, I've only seen this once I actually release the app, and *have NOT *bought it myself.

It shouldn't be too difficult.

[android-developers] Re: totally 2d
Bob, I recently released a game (actually just this week, called Prism or Prism Light by Shadowpuppets), which doesn't use OpenGL at all. I just draw onto the canvas from my overrided onDraw method, and then invalidate only the part of the view which contains animation. I have determined that the drawing portion is the bottleneck for me (i.e. all the physics calculations and the rest of the game engine have no effect on the framerate). For your reference, I have an original Motorola Droid and I generally get around 60 frames per second of animation. During beta testing, other users with more advanced phones got upwards of 100 frames per second (I actually had to put a frame rate limiter in my game to keep it at 60 fps max). *However!* This is my experience only and is unique to my game. If you download and play the free version, then you'll notice that my game board only takes up about 2/3 of the screen (and that is the *only* part of the screen which can be animated in my game). Furthermore, the performance increased drastically when I clipped the regions of the screen which didn't contain any animation. For example, my worst possible case scenario was needing to animation something in the top left corner and the bottom right corner at the same time. This causes the entire view to be redrawn and results in my worst frame rate scenario. In this case, the frame rate dropped to around 40 or 45 fps. At any other time, when the clipped region didn't take up the entire game board the frame rate increased upwards and past 60 fps (of note: even though the region was clipped, I still drew all the animations to the canvas, even if they were totally outside the clipped region. This didn't seem to affect the increased frame rate -- that is, it mostly depended on what actually gets pushed out to the screen buffers). So, it varies, but overall I got acceptable performance. Also, depending on what devices you target, there are other options. For instance, if you're just targeting Honeycomb then you can enable hardware acceleration for your view with only the addition of 1 line of Java code (see the Developer's Guide recent Blog on the subject). I haven't tried using OpenGL for my game, because overall I didn't need it. I was prepared to try, but I found that drawing my 2D animated game onto a view's canvas was sufficient for my purposes. I hope that this gives you the perspective you were looking for. Nick -- You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] Re: Why can't draw a picture on canvas
It appears, by your code, that you *are* drawing on the bitmap through the canvas. However, I'm guessing your *real* question is: why is my bitmap not being displayed on the screen? Well, that's because your bitmap or canvas is not associated at all with any buffers which finally get displayed on your device. Here are 2 options for you: 1) If you're just trying to display a picture to the screen that doesn't change, then just put an ImageView in your view hierarchy and define the android:src=R.drawable.bg. 2) If you're end goal is to do custom drawing onto the screen, then you're going to have to create a custom view and override the onDraw method, which *gives* you the Canvas object which is linked to the display. Remember, a Canvas is just a tool for drawing onto a bitmap. It has, inherently, nothing to do with drawing something to the screen.

(Android app): Collect data, get saved login information
(Android app): Post data to my server
(Webserver): Gather the data (in $_POST['username'], $_POST['password'],
and $_POST['data']) and insert it however you need to.
(Webserver): Return success or failure through a JSON object (e.g.
echo(json_encode(array('status'='ok', 'error_message' = ''
(Android app): Parse the JSON object, and look for either an ok status or
and error status.

Once you're comfortable with that program, then you can probably ask more specific questions here that we might help you with. Try looking at this sampe: Lunar Landerhttp://developer.android.com/resources/samples/LunarLander/index.html .

[android-developers] Re: rotating a bitmap
A couple things: This might help your pivot point that you have: instead of converting to float after the division, try doing it before the division. Like this: ((float)mBitmap.getHeight())/2f -- I believe you are losing some accuracy by doing it the other way around. As in (float)(7/2) would equal 3, not 3.5. Secondly, if you're end goal is to just draw a rotated image to the canvas during the onDraw call (which I suspect that it is), then there's no reason to create a second bitmap. Something like this should work: float px = ((float)mBitmap.getHeight())/2f; float py = ((float)mBitmap.getWidth())/2f; m.setRotate(mRotation, px, py); canvas.drawBitmap(mBitmap, m, null); Also, if you're not doing anything funky with your paint (like ColorFilters, etc.), then just leave it null. --Nick -- You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] Prism - Please help test my puzzle game! (Release Candidate)
Hello all, I'm about a week or so away from releasing my first video game on the Android Market. It's a puzzle game with 100 levels of brain busting goodness, and I'm very excited about it. However, I only have my original Moto Droid to test the app -- and I don't really trust the emulators to give me an accurate frame rate prediction. I was hoping to solicit your help in making sure everything's up to par. All the bugs have been worked out (that I know of), so it's by and large a fully complete game. However, I suspect that some configurations might get a force close here and there, and that's what I'm worried about. Also, I'd like to know what frame rate you are getting and on what device. I've included a permanent fps indicator in my pre-release beta build, and it's capped at 60fps. As a reference, my original Moto Droid gets 60 fps about 95% of the time. All you need is Android 1.6 or higher. You can *download the APK herehttp://androidshadowpuppets.com/Prism *. I'm looking for testers with any Android device, even a tablet, if somebody has one who is willing to give it a shot. Please let me know what you think, and if you find any bugs. Thanks!

Re: [android-developers] Emulator snapshots in API 9 work with older API levels
My Eclipse plugin for Android Development is updated to 9.0.0 but still I am not able to see any Save to Snapshot option in the launch window.

It took me a while to figure out how to use it so wanted to share it here : CREATE AN AVM SNAPSHOT * Set the Snapshot Enabled checkbox in the SDK Manager Virtual Devices New... NOTE : Make sure you upgrade your Eclipse plugin for Android Development to 9.0.0 or the Snapshot Enabled feature wont show. * Start your AVM and enable the `Save to Snapshot` checkbox, then click Launch button * Once the AVM is running.

[android-developers] Re: Best Android Game Engine?
I have been using rokon for a few months since before version 2. My first game I released using it is called Android Recon. You can check it out on the android market if you want. I have been looking at AndEngine as too. From browsing there website it looks like it has some stuff that rokon does not yet have. Like the ability to load Tiled Maps. That will be very useful for many types of games. Also jMonkeyEngine 3 should be coming to android soon if you are thinking about a 3d game. And there are a few paid engines like ShiVa 3D, and Unity 3d will be coming to android. -- You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] Managing a suite of applications
I asked this on Stackoverflow, and got my first tumbleweed, so I thought I would give it a chance here. :) I'm building a suite of applications, meaning that I have a single set of code that gets customized via a single change of an API key. This means that all of the applications have the same activities, same behaviors, but different icons, package names, and application names depending on the client I am building for. Unfortunately, I haven't figured out a clean way to do this. Because the package name is what the Android Marketplace uses, I've been changing it to com.nilobject.productname.clientname. However, this changes the package for all of the activities to no longer be in the package of the application, since they live in com.nilobject.productname. Additionally, the autogenerated R moves, so all of the references to R in com.nilobject.productname break. Has anyone else dealt with this problem? I'm using Eclipse for development. Should I just refactor the activities with each build to be in the same package? Is there a system for this that I don't know about?

[android-developers] Cannot sync Calendar with Google Calendar service on emulator
Hi,
I run the 1.0r1 emulator and install Calendar.apk and CalendarProvider.apk
on the emulator. And I configure the username and pwd from DevTools-Google
Service Login successfully.
Now I can start the Calendar app successfully, with the month view/week
view/etc. But I don't know how to sync the calendars or events with Google
Calendar service. From the source code, I assume there should happen sync
operation. But it didn't happened. And I know another trigger to sync is
