[android-developers] Android Spinner Issue
I have a data entry layout that defines 5 spinners. Each spinner has properties defined that are identical, apart from id, hint text and so on. When rendered they all have different background and text colors. These are all defined to be the same. The containing layout has a style defined which should apply to everything in the layout. Does anyone know why this would occur? Answers really appreciated. -- You received this message because you are subscribed to the Google Groups "Android Developers" group.

[android-developers] Android Studio Initial Run
After developing with AS for over a year, the IDE became very unresponsive. Just setting the cursor in a line of code I'd have to wait 3 or 4 seconds until I could type anything. Background tasks, like build, were unaffected. All other apps on my PC were normal. So, I uninstalled AS, and deleted all associated folders and re-installed v 2.2. On the initial run I'm asked to enter Proxy info. I'm not connected to a proxy server, but I cannot get past this step. The original install never asked for this info. So what the heck is going on?

[android-developers] TabLayout problem
I've built an app that uses TabLayout. Each tab displays correctly in a
scrollable horizontal toolbar. However, it displays the layout for Tab 1,
by default and I do not want anything displayed until the onTabSelected
code is fired. ie; Do not display anything (except for the tabs) until I
click/select a specific tab. Whatever layout associated with the tab is
displayed without my selecting the tab. Providing a solution would be
greatly appreciated.
Here's relevant code:
setContentView(R.layout.main_activity_scrollable_tabs);
toolbar = (Toolbar) findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
getSupportActionBar().setDisplayHomeAsUpEnabled(true);
viewPager = (ViewPager) findViewById(R.id.viewpager);
setupViewPager(viewPager);
tabLayout = (TabLayout) findViewById(R.id.main_tabs);
tabLayout.setupWithViewPager(viewPager);
tabLayout.addOnTabSelectedListener(
new TabLayout.ViewPagerOnTabSelectedListener(viewPager) {
@Override
public void onTabSelected(TabLayout.Tab tab) {
super.onTabSelected(tab);
Intent intent;
// position zero-based! ie; tab one is pos 0.
numTab = tab.getPosition();
switch (numTab) {
case 0:
intent = new Intent(context, PeopleEntryActivity.class);
startActivityForResult(intent, 0);

[android-developers] Using Callbacks in Master-Detail Scenario.
I have a typical master-detail scenario. That is, first activity invokes a list fragment in which I retrieve a list using a contentprovider. An Item click on this list returns the row using a callback to activity. Activity determines device type and either fires a detail fragment (for tablets etc) or fires a detail activity (for phones). I am trying to update the list in the list activity following an update, or a delete. The adapter is located in the list fragment - as is normal. I have coded callbacks from the detail activity to the first activity. That did not work. I've done the same thing but calling back to the list fragment. That does not work. I created a hard-coded reference to the ListFragment adapter in the DetailFragment in order to call ' notifyDataSetChanged' which not surprisingly also did not work.

[android-developers] ContentValues issue
First, as a long-time Java developer I'm now learning Android. I have an app in which I use the ContentValues class to supply data to a Class that extends ContentProvider. Here's the issue. I'm 'put'ing 5 values (from a layout) into the ContentValues class. The problem - not all values are getting assigned. All values are of type String and they are valid values. Here is my code: int numColumns = 5; ContentValues newRideValues = new ContentValues(numColumns); newRideValues.put(KEY_RIDEDATE, rideDate); newRideValues.put(KEY_DURATION, rideDuration.getText().toString()); newRideValues.put(KEY_WEATHER, weather.getText().toString()); newRideValues.put(KEY_DISTANCE, distance.getText().toString()); newRideValues.put(KEY_EXERCISE_TYPE, radioExerciseButton.toString()); rideDate never gets assigned and the other values seem to not be assigned in order ie; distance may end up being the second element, when I would have expected rideDate to be the first and distance to be the fourth. This is how I use the newRideValues collection. new BikingLogsContentProvider().insert(CONTENT_URI, newRideValues); Any ideas and suggestions would be very welcome. -- You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] Software Keyboard
Hi lads, I'm running into trouble trying to make the software keyboard pop. I've already read all the posts related to that but unfortunately none helped me. I tried toggleSoftInputFromWindow, showSoftInput, getWindow().setSoftInputMode() with all possible combinations and all possible flags. I don't have an EditText, so I even tried to create a fake one. I made the call from different listeners to make sure it was not a thread related issue. I tried to delay the thread a bit. Still, those methods always return false and therefore the keyboard doesn't show... BUT! Everything works as expected as soon as I minimize the application (by pressing Home) and restore the application. From then, the keyboard shows up without any problems. Any clues? Phil.

[android-developers] Re: LVL, DeviceLimiter and userId
In the developer console active installs is supposed to be the number of devices that the software is currently installed on. I know how many successful sales have gone through Google Checkout (this is lower than the total installs on the developer console which I think includes purchases cancelled inside the 15 minute returns window) and the active installs figure is 40% higher than the total of successful sales. My conclusion, given that most of my sales are in the USA, is that couples/families where at least a couple of people have an Android phone may be sharing a generic Google Checkout account so that they can buy an app once and share it around for free. That's ok-ish when there is no ongoing cost of running a back end server. It's going to destroy my business model if I need a back end server though. I'm considering using the Google Order Number as a licence key, thereby allowing multiple installations, but no simultaneous use on different devices. And I'll write up a licence to reflect that.

I've one app in the Android Market that uses LVL in its recommended form, so users can install the application on any device they have set up their account on. Early indications are that the software is being repeat-installed at a higher rate than I'd expect - 40% of users have my application installed on more than one device. That seems a bit high but, for that application in particular, it is no more significant than some lost sales - there are no ongoing running costs for me to support. It is enough to make me concerned about my next app though, which requires a server in the cloud. Application sales should cover the cost of this but if the repeat installation rate is high, my application may not be sustainable in the medium to long term - server costs will eat into income and I could end up running at a significant loss - and the more popular the app becomes, the bigger that problem is. So this got me thinking. Repeat installations by one used are not a problem, but one core function will account for the majority of server load - both processing and bandwidth. So, my tentative thought is that if a user is currently using that core function on one of their devices, they will not be able to use that function on any other until they are done with it on the first device. To be able to implement this I need access to a piece of data that is common to all the installations, which brings me round to the DeviceLimiter interface. Is the userId supplied here the same for a given application, purchased by a single user, regardless of the device it is installed on? Or is it the ANDROID_ID for the device? I don't want any identifying information (like an email address), I just want to be able to spot, from my server code, when multiple instances of a single purchase are using my (relatively) expensive resources simultaneously. A fall back solution would involve the user putting in their Google Checkout order number to activate the application - is there a service exposed to securely obtain details about an order that my server could make use of?

[android-developers] Re: LVL, DeviceLimiter and userId
OK after playing with two different accounts across three different devices... the userId passed to DeviceLimiter is maintained across devices and between wipes. So, if a user has purchased an LVL licenced application, DeviceLimiter will always receive the same userId string. Therefore, it is possible to tell how many devices an application is being used across by using, for example, a cookie type approach. -- You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] LVL, DeviceLimiter and userId
I'm looking at the LVL code and had a question about user identity and the DeviceLimiter interface. I've one app in the Android Market that uses LVL in its recommended form, so users can install the application on any device they have set up their account on. Early indications are that the software is being repeat-installed at a higher rate than I'd expect - 40% of users have my application installed on more than one device. That seems a bit high but, for that application in particular, it is no more significant than some lost sales - there are no ongoing running costs for me to support. It is enough to make me concerned about my next app though, which requires a server in the cloud. Application sales should cover the cost of this but if the repeat installation rate is high, my application may not be sustainable in the medium to long term - server costs will eat into income and I could end up running at a significant loss - and the more popular the app becomes, the bigger that problem is. So this got me thinking. Repeat installations by one used are not a problem, but one core function will account for the majority of server load - both processing and bandwidth. So, my tentative thought is that if a user is currently using that core function on one of their devices, they will not be able to use that function on any other until they are done with it on the first device. To be able to implement this I need access to a piece of data that is common to all the installations, which brings me round to the DeviceLimiter interface. Is the userId supplied here the same for a given application, purchased by a single user, regardless of the device it is installed on? Or is it the ANDROID_ID for the device? I don't want any identifying information (like an email address), I just want to be able to spot, from my server code, when multiple instances of a single purchase are using my (relatively) expensive resources simultaneously. A fall back solution would involve the user putting in their Google Checkout order number to activate the application - is there a service exposed to securely obtain details about an order that my server could make use of? All I really need is to know is the application purchased.

[android-developers] Controlling mutually exclusive preference categories with a single parent checkbox
I'm trying to work out how to implement a preferences XML file that has two mutually exclusive preference categories, only one of which is displayed and enabled based on a parent checkbox preference. When checked, category 'a' should be displayed and 'b' hidden. When unchecked, category 'a' should be hidden and 'b' displayed. Now the android:dependency property allows me to identify a controlling parent preference, but the parent value that disables the dependency is specified on the parent (the android:disableDependentsState property). So it appears that I can't enable one category while disabling another: CheckBoxPreference android:key=use_option_one android:title=@string/use_option_one android:summary=@string/use_option_one_summary android:defaultValue=true / PreferenceCategory android:title=@string/option_one_options android:dependency=use_option_one android:shouldDisableView=true ... /PreferenceCategory PreferenceCategory android:title=@string/option_two_options android:dependency=use_option_one android:shouldDisableView=true ... /PreferenceCategory I've tried !use_option_one out of curiosity but this is not a supported syntax. Can somebody confirm (a) that my understanding is correct and (b) suggest an alternative implementation pattern to achieve the desired effect?

[android-developers] Fragments API 11+ vs Compatibility package
Hi, I've just started playing around with fragments to make some apps work better with tablets. I've got this working nicely with my SGS and Xoom using just the compatibility package (trying to mix both resulted in crashes as I'm using the same fragment classes for both), which means I had to extend FragmentActivity for all my Activities and removed any references to android.app.Fragment in favour of the compatibility library version. I was wondering if this is the best way to implement fragments, as even API 11+ uses the compatibility package? (It's certainly the cleanest way and no code duplication) Also are there any implications/loss of features etc by doing this, or are the packages/functionality identical? Thanks!

I'm not at all sure that it does.
Then
you can use that to lay out your ruler markings:
int pxPerInch = 340; // default value - note it's a new density
in API version 9.
switch(densityDpi){
case DisplayMetrics.DENSITY_LOW:
pxPerInch = 120 * scale;
break;
case DisplayMetrics.DENSITY_MEDIUM:
pxPerInch = 160 * scale;
break;
case DisplayMetrics.DENSITY_HIGH:
pxPerInch = 240 * scale;
break;
}
Note that the values of those constants DENSITY_* are their numeric
values, so there is no need for the case statement; you can just
write:
pxPerInch = densityDpi * scale;
However, I really don't think that does what you believe it does. I
think that densityDpi reliably gives the approximate dpi, and density
just gives densityDpi/160. Multiplying them together doesn't do
anything useful. But I could be wrong!
Thanks, Phil.

[android-developers] Re: Simple compass functionality
I'm now trying to understand how to allow for the display orientation in my simple compass calculation, since I don't think there is an API that does that for me. It looks like the right way to get this is getWindowManager().getDefaultDisplay().getRotation() which returns values Surface.ROTATION_0 ... Surface.ROTATION_270. But that is only available in API version 8, which I don't have. There is a deprecated method Display.getOrientation(). Perhaps that is what I'm supposed to use, however its docs seem to have been removed when it was deprecated (Please Don't Do That!). Googling suggests that perhaps it returns values like Configuration.ORIENTATION_PORTRAIT and Configuration.ORIENTATION_LANDSCAPE, i.e. not including left or right or upside-down information, making it useless. Surely there must be some easy way to do this? (Related question: compass calibration. Is there ever anything like the iPhone's calibration dialog? I wasted much of this morning thinking there was something wrong with my code, until I realised that the compass also didn't work in Google Maps on my Galaxy Tab. I spent a few minutes slowly turning the device on each axis a few times and it now works better. This is the sort of issue that users will blame on the app, and that will be impossible to debug remotely...) -- You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] Simple compass functionality
Dear Experts, I'm trying to understand how to get simple compass functionality working, i.e. I have a map that I want to add a facing this way arrow to. I don't need other orientation angles i.e. it's not Augmented Reality, but I do need it to work correctly as the display orientation changes. I know about magnetic deviation but will overlook it in this post. As far as I can see, there is a reasonably simple deprecated method: I getDefaultSensor(TYPE_ORIENTATION), and use values[0]. It's unfortunate that this is deprecated. The replacement for this deprecated method seems to be: 1. getDefaultSensor(TYPE_GRAVITY) and getDefaultSensor(TYPE_MAGNETIC_FIELD) 2. When I have new values from both sensors (which don't necessarily arrive at the same rate), pass them to getRotationMatrix() and then pass the rotation matrix to getOrientation() to get the angles. ...but that doesn't allow for the display orientation. I think that I need to get that (from where?) and subtract it from the result. ...and I also don't think it does the right thing when I am holding the device near-vertically. Say you're standing, facing East, holding the device in front of your face, viewing a map; it will have East at the top. But if you tilt the device so it is slightly overhanging, this method will flip it so that West is at the top, won't it? That's certainly not what the user would expect. ...and I don't really think the accelerometer is needed for this. I think the accelerometer is only really needed to get the two other outputs (pitch and roll) from getOrientation() that I ignore. Though I may be wrong about that, if I fix the previous issue, due to varying magnetic dip angles. So, has anyone else worked out how all of this should hang together? Is there some simpler API somewhere that I have missed? Thanks, Phil. -- You received this message because you are subscribed to the Google Groups Android Developers group.

I've read about picking in OpenGL Beware that selection mode is not available in OpenGL ES. I want to understand if there are other solutions. You have various options, but none is simple: 1. unproject from the (x,y) screen coordinates to a ray in model space, and work out which object(s) intersect that ray. 2. unproject from the (x,y) screen coordinates and the corresponding z coordinate from the depth buffer to a point in model space, and work out which object includes that point. 3. Draw your entire scene a second time into an off-screen framebuffer (possibly at lower resolution), but instead of using the objects' actual textures or colours, use a unique colour for each object. Then just look at the colour in this framebuffer at the selected (x,y) point, and you can decode the corresponding object. These are all general techniques. Sometimes your application will have characteristics that let you do something simpler, e.g. a constrained projection or object layout. Good luck!

[android-developers] Strategies for large apps
Dear All, I have just discovered that the Android Market limits apps to a maximum size of 25 MB. Is that really true? My most popular iPhone apps are 68 MB, 180 MB and 318 MB respectively. Although I have one of them ported now, I can't sell it in its current form. So my options are probably: - Substantially strip down the content in the Android versions. - Distribute the app not via the Market. - Download the data when the app first runs. - Wait and see if this size limit is changed (*). Only the third option seems sane. I do have server infrastructure that could be used; the main challenge is the required code. The apps currently consist almost entirely of C++ OpenGL with a very minimal Java wrapper (literally one page). If I download from C++ I need to write an OpenGL GUI to display while it happens. If I download from Java, well, I need to learn about 20 times more Java than I know right now; in either case, I need to learn a whole load of stuff about the filesystem layout. So I'm hoping that someone can either suggest a work-around, or perhaps point me to some nice example code that accomplishes this, or maybe would even offer to do it for me ($!) (*) I mention the possibility that it might change because (a) there is now the install to SD option in 2.2, and (b) there do seem to be changes afoot in the market.

[android-developers] Making window full-screen on Galaxy Tab
Dear All,
I have a simple app that is mostly native-code OpenGL with about a
page of Java to interface to it. On my new Galaxy Tab, it creates a
window that is about 480x800 pixels, while on other devices (including
an AC100 with a larger screen) it fills the whole screen.
Searching the web, it seems that this affects many existing apps when
they are run on this device, and there is plenty of end-user advice
about how to make apps fill the screen. But I've failed to find any
advice about how I should do it from within the app.
My current Java code is not much more than this:
public class FooActivity extends Activity
{
@Override
public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
gl_view = new FooGLSurfaceView(this);
setContentView(gl_view);
}
..
}
My impression is that that will generally create a full-screen view on
devices other than the Galaxy Tab.
I've experimented with passing a
ViewGroup.LayoutParams(FILL_PARENT,FILL_PARENT) as a second parameter
to setContentView, but that doesn't change anything. From what I
understand of the docs, I should perhaps be changing the window
properties to ask for full-screen mode, but it's not obvious to me how
to do that; how do I get the current window?
Can anyone help?
Many thanks, Phil.

Mark, Thanks for your reply. I'm not sure when my original message got approved - I missed it and your reply - and in the meantime found this for myself in the source code. Interestingly there must be another way to do this than through the official hidden API as there is at least one hot spot widget in the marketplace already. I tried writing a spoof version of android.net.wifi.WifiManager which allowed me to compile and deploy the code, but this results in a noSuchMethod error at runtime - so the @hide annotation applies not just to what gets put into the SDK API that I compile against in Eclipse - although the Reflection API shows that these methods are present.

[android-developers] Re: Android 2.2 - Portable Hot Spot - WifiManager class
Mark, Yes, what I am doing is first and foremost for my own benefit and not a financial one... I've not decided whether to put this out as a free download in the app store yet. I have something working now and it's been a satisfying puzzle to crack. I gather that this approach might be used to provide tethering on 2.2 devices that don't have the capability enabled by the carrier. Personally I'd rather Google bundle a widget if they're not yet willing to make the API public. I find myself frequently needing to turn the AP on for a few minutes before turning it off again on client premises. Phil.

[android-developers] Re: Android 2.2 - Portable Hot Spot - WifiManager class
I think if a small company is willing to put out such a widget they should also be willing to keep up with API updates, or pull the widget. Personally, having solved the problem, I will use this for a while and if it proves reliable I will strongly consider pushing it out as a freebie. After all, if I find it useful then I will want to use and maintain it until such time as it is superseded by a built-in widget. As for crap market ratings, my experience as a user is that even good products get crap ratings when the user doesn't understand them properly. If the widget is unable to function as designed, it needs to inform the user of this fact. If the user understands why the widget won't work, then they are less likely to take their frustration out on the supplier of said widget. Personally I think Google had it right with the distribution model for the Nexus One; I've just picked up a Galaxy Tab (which supports AP on Vodofone UK) and the stock applications have been replaced or 'enhanced' for no obvious reason, which I think is some of the reason behind bad reviews from (eg) Gizmodo. If Google didn't have to kowtow to the networks then AP functionality probably wouldn't have been marked as hidden in the first place.

If the developers of Android don't want people using particular functions in a stock ROM they need to put a permission on them.

[android-developers] Product images for marketing materials
Dear All, What do people know about rights to reproduce device graphics for web sites and marketing materials? I have some great images of the Galaxy Tab that were published with their launch press release, and I have assembled a flyer showing my app running on it. However, my printer won't print it unless I can convince him that I have the right to do so. I've spent a long time trying to reach the right person at Samsung but so far without any luck (you are in a twisty maze of telephone menu options, press 1 to abandon hope). So, I'm wondering if anyone has any experience to share or perhaps suggestions of other manufacturers whose material is published with a clear re-use rights statement. If not, the flyer is only going to have pictures of Apple devices on it, which would be unfortunate.

[android-developers] Looking for interns as Android Developers
Hi all I know I've left my run a bit late for this summer, but if there are any students looking for intern roles over the summer who want to get involved in an exciting Android research project, then I have two positions available in the San Francisco bay area (Pleasanton on the East Bay to be precise). Majura (www.majura.com) was recently founded to build a completely new approach to device security - we've already been able to garner a lot of attention and significant funding. We're looking for two interns right now to help complete our initial proof-of-concept. We don't care about years of experience and a one inch thick resume - rather we want people that understand the new wave of non-PC devices, and of course know how to develop on these platforms - if you're really talented Linux programmer, we'll even teach you how to do Android development. A mathematics background would be useful, as we have some heavy duty algorithms in our approach. A passion for the coming wave of non-PC devices is essential - we're not just building apps here, but a whole infrastructure service that is targeted at business (initially) and then consumers. Android is just our initial platform, and we're planning to extend this to any system, such as Smartgrid. The founders are extremely experienced and have bought and sold numerous companies, building businesses from $0 to $100M in four years, and making people rich in the process. We also like to have fun in the office and often have business meetings out on a hike in the nearby parks - none of those sterile silicon valley offices for us! I know the website is lame right now so don't complain. And we're not hiring beyond interns right now, and do really need them local - once we kick this into the next phase we'll start general hiring. Look forward to hearing from you!

[android-developers] Re: 2-D Graphics Performance after Motorola Droid 2.1 Update
patbenatar, Verizon started the rollout of 2.1 to Droid devices earlier this week. If it has been halted, it's news to me. On Apr 2, 10:30 pm, patbenatar patbena...@gmail.com wrote: If you updated to 2.1, you must have root and have installed some custom ROM, correct? Motorola has not yet rolled out 2.1 updates [and from what I've been hearing they've put it on some sort of indefinite hiatus] so any version of 2.1 you're running is not OFFICIALLY built for Droid... Maybe the ROM is the reason for this behavior? What ROM are you running?

[android-developers] R.xml cannot be resolved
In case anyone is interested (I might be saving your life here) I had the error - R.xml cannot be resolved - no visible solution - on a GLS project. h. After looking in R.java I found an auto generated class XML.java (I think) was not there and should have been. I guessed the solution - impossible to work it out exactly yourself! Solution? It needed a new folder in res: res\xml and a file called default_values.xml in there. Then all OK. Just in case you have not got that file its: (less than) ?xml version=1.0 encoding=utf-8?
