Re: [android-developers] Suspended android developer account
Dear Mobejakt, I met a similar problem. I wrote an application and put it in Android Market. The user feedback are great and it makes me feel I would continue develop and create more feature to fulfill user's requirement. But 3-day before, I get Google's notification and they suspend my app in Android Market. In the notification email, it said I can reply it and get more detail information. I did as they said. But I get nothing from them. I'm still confused after I reviewed their content policy several times. I think I never break them. But Google just suspend my app and no any feedback of my question email. The users are great. They send me email and ask for reason. They show their supportive. But some user starts to doubt whether I put spy into my app. That really makes me feel bad. I use my whole spare time to develop the app, but now I start to be doubted by my user.

Suddenly this increased 10 folds and with all 1 star reviews coming in on bundles. We suspected foul play but unfortunately there wasn't much to do about it however we used the forms for android developers and notified Google about this, hoping that they would be able to detect what was going on.

[android-developers] Re: Career as an Andoid developer. Is there any point?
Hate to break up this tender moment, but I'd like to get back to the original statement: Additionally, Android, as it's currently designed, does not have legs. The process model and UI are both too restrictive to be extendable to the pads and other new paradigms of the future. Who would have guessed that MS-DOS/Windows/Windows NT/Windows had legs? Or Mac Os? And do any of the modern day instances of those technologies bear much resemblance to their roots at two years into their existence? Would anyone have made a career of being an Windows programmer (and would that have necessarily been a bad call given the data at the time)? Is anyone really predicting that the Linux process model is going to doom Android? If so, when? And does anyone really think the UI is going to stay the way it is today (and for that matter, has anyone observed that the legged Windows and Mac have evolved over time)? On these terms, I still think it's rash to have made the above statement given that change has been and will continue persist on the Android platform. I think that's what's got everyone upset here. It's just too early to call, unless you have a proven history of making those calls. (And if you do have that history, please also tell me your 100% guaranteed top stock picks for the next 10 years!) FWIW, I moved 3000 miles across the US to make a career switch from web dev (15 years) to Android (2 years) and it's not turned out bad for me at all. I have more compelling job offers and opportunities than any other time in my life. The next time I detect a future trend, I might chase that as well and try to master it. But then again, I have a education in Computer Science and a history of making stuff work that people want to pay for, regardless of platform. But I'm in no way changing what I do today nor making plans to change. Doug -- You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] Re: Career as an Andoid developer. Is there any point?
Like any occupation, unless you're some sort of savant you need to spend about 2000 hours (a year) working at it to achieve basic competence, and 10,000 hours (five years) to become an expert. If you're not prepared to spend that sort of time working at it, then find a different occupation. Dan, in the beginning I completely disagreed with the things you wrote, but I completely agree with what you've written in your last message (although I still believe Android is a good framework:-) ). Yes indeed, anybody who is not willing to spend that much time, should better be a consumer of applications at the Marketplace. The hours you should spend to gain good insight and expertise may vary depending on your experience, but the final message is that you should work hard and spend time. I like the Android framework and I believe that developing applications for Android is a good step to get involved in mobile development. However, I don't like certain things around it. One example is the App Inventor. I've never used it; maybe it can be a helpful tool for people with software engineering background to start a new application very fast. However, App Inventor and the things you can do with it, is either perceived wrongly (in this case Google should deliver the message better) or deliberately marketed with overpromisses (hoax, hoax, hoax!!!). I've seen people who have never written a single for-loop in their life, trying to develop applications with the App Inventor and make money with it. One can always argue that natural selection will eventually eliminate such people, but they will also cause pollution which could hurt the credibility of the framework. (The following is just a hypothetical question, I've not done a statistical analysis in the Marketplace). If 5 out of 10 applications I find in the Marketplace would be rubbish, would I bother searching it in the long run for applications and would I continue using Android? I don't mean that this is the current situation in the Marketplace, by no means. But giving people a tool like App Inventor and then either not delivering the message correctly or deliberately marketing it with empty promises, has the risk to backfire and maybe it's not worth taking that risk. Software development cannot be 100% automated. Period. -Ali On May 29, 6:07 am, DanH danhi...@ieee.org wrote: Yeah, Bob, I think you mostly understand where I was coming from: 1) Don't focus your career on any single technology or product but rather seek to have a broad-based, multi-specialty background and the flexibility to move from project to project. And don't short-change learning the fundamentals. 2) Don't expect to strike it rich on some viral app. Work up a plan for who your customer is and how you will serve their needs. In terms of marketing, market yourself to a few people (ie, other companies) rather than the masses. Mass marketing is simply beyond the capabilities of an individual developer. I do take issue with the argument that there's no room for innovation with big (or small) corporations. I've spent most of my career (about 36 years) working for large corporations, and, save for the last 2-3 years of that time (when my employer essentially decided they were out of the innovation business), I was always innovating, in small and large ways. I have my name on something like 20 patents, I won several awards from my company, and I had the opportunity to work on a number of interesting projects. But the main point I'd make is that programming is HARD WORK. I see too many people on various forums (actually less here than elsewhere) who try to get into it without doing their homework, figuring they can get along by just modifying sample programs, lashing together bits of code they've Googled, begging experienced people to do their work for them. You might be able to lash together some app that sells a few hundred copies in the Marketplace this way, but it's not going to even pay the rent, much less put a kid through college or buy you a house.

So are you saying the NFC would not be good for a Bump-type comm between two devices? It just seems so much easier than pairing two Bluetooth devices and since Android doesn't even support peer-to-peert WIFI networking, that's completely out of the question. On May 29, 9:13 am, Bob Kerns r...@acm.org wrote: Send? Just what do you think NFC is, exactly? It sounds like you think it's an alternative to WiFi or Bluetooth. That's not exactly true, or only approximately true, depending on how you want to look at it. While in theory you could use it to communicate between two devices, the short range involved, and the low speed, make it less than attractive for this. If you Bluetooth or WiFi available, those would be much more natural. So you may want to rethink whether this is the right tool for your job.

[android-developers] Re: Lifetime of static [instance] variables
Replying back to the list. Most (all?) platforms' model is process == application (more or less). In Android, there really is no such thing as the application (there is, but it is useful to ignore it at first). Therefore, one should unlearn that equality between application and process The unit of installation is package, and the unit of execution is component. Components come in various shapes: activity, broadcast receiver, service, content provider, etc. These components have well defined lifecycles with callbacks. On the other hand, a process is more or less just an implementation detail, having to do more with memory and file protection, crash handling, dealing with out of memory situations, etc. Android keeps processes running as long as possible while there is enough memory. This significantly improves performance if the user or the system again needs one of the components provided by this process.

[android-developers] Re: Career as an Andoid developer. Is there any point?
Let me tell you something: When a company hires you to do an app (or your management in a large company asks for some new software function of any sort), nine times out of ten they don''t have the foggiest idea what they want you to do. Even if they have a 50-page spec, it'll be more concerned with legalese than actual function. While it can be frustrating and painful to drag out of them the expected function, and negotiate how it will be implemented, the opportunities for innovation are substantial. (In a couple of cases I was given free rein in developing multi-million $ projects.) Certainly there's a trade-off -- working for yourself you only have to negotiate with yourself. But for many programmers (who often as not have more than a touch of ADHD) having some external source of direction (and schedule pressure) can actually be helpful -- helps keep you from running around in circles forever. And, while the negotiations with a company can be painful, there are, as I'm fond of saying, toilets to be cleaned in any occupation. It comes with the job. Don't expect working for yourself to be pain-free and not involve a substantial amount of dog work. On May 28, 11:59 pm, Bob Kerns r...@acm.org wrote: I meant something far more narrow.

This is in contrast with doing something on your own, where you have a wide open field, and can pursue whatever idea interests you. The question of whether you can innovate in a large company depends a lot on both you and the company. Some large companies are quite well known for encouraging innovation. To take one very significant (though somewhat historical) example: Xerox. I've worked in Digital Equipment's Cambridge Research Lab. Plenty of room to explore and innovate there. But had I been hired, even as an employee, to create an Android app, that would be different -- at least for the life of that product. Sometimes that kind of relationship though can be a route into a company, and lead to more interesting work. I'd like to highlight one thing you said: I was always innovating, in small and large ways. That's a good attitude, and expectation, to go into any work, even the most narrowly defined. There's always room for innovation in small ways, and you will always learn more, be worth more, and have more fun.

App Inventor is just COBOL warmed over. Nothing changes. Like COBOL, I'm sure that App Inventor has it's uses, but neither will eliminate the need for trained programmers. SQL was also touted as eliminating the need for programmers, and now it's developed into its own programming specialty.

Dan, in the beginning I completely disagreed with the things you wrote, but I completely agree with what you've written in your last message (although I still believe Android is a good framework:-) ). Yes indeed, anybody who is not willing to spend that much time, should better be a consumer of applications at the Marketplace. The hours you should spend to gain good insight and expertise may vary depending on your experience, but the final message is that you should work hard and spend time. I like the Android framework and I believe that developing applications for Android is a good step to get involved in mobile development. However, I don't like certain things around it. One example is the App Inventor. I've never used it; maybe it can be a helpful tool for people with software engineering background to start a new application very fast. However, App Inventor and the things you can do with it, is either perceived wrongly (in this case Google should deliver the message better) or deliberately marketed with overpromisses (hoax, hoax, hoax!!!). I've seen people who have never written a single for-loop in their life, trying to develop applications with the App Inventor and make money with it. One can always argue that natural selection will eventually eliminate such people, but they will also cause pollution which could hurt the credibility of the framework. (The following is just a hypothetical question, I've not done a statistical analysis in the Marketplace). If 5 out of 10 applications I find in the Marketplace would be rubbish, would I bother searching it in the long run for applications and would I continue using Android? I don't mean that this is the current situation in the Marketplace, by no means. But giving people a tool like App Inventor and then either not delivering the message correctly or deliberately marketing it with empty promises, has the risk to backfire and maybe it's not worth taking that risk.

If you're not prepared to spend that sort of time working at it, then find a different occupation. -- You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] Re: Network operation every half sec.
Anyone out there who had handled such type of scenarios previously? Regards, Mahavir On Sun, May 29, 2011 at 7:51 AM, Mahavir Jain vir.j...@gmail.com wrote: Hi, I want to make network operation in every half sec and depending on data, i want to update the ListView continuously. Following is my approach: Using thread and handler.postDelayed, it makes the network request every sec and update only those views of the row in ListView which needs to be updated. It does not update ListView using notifyDatasetChanged(). Though it updates the UI, but it takes time in updating the UI. Is it because, I am using emulator? Is this the right approach for this scenario? Any other best approach for this? Anyone handled such scenarios previously? Thanks in advance.

[android-developers] Does new Google Music Beta support end user selection of songs via intents
I have an application that uses ACTION_PICK to allow the user to pick
a song. Once that song is picked, the application uses the cursor
location and does another intent later on to show the NOW_PLAYING
interface. The application worked fine until I installed Music Beta
on my droid device. The application then began failing with
UnsupportedOperationException. The intent and filters looked like
this:
Intent intent = new Intent(Intent.ACTION_PICK);
intent.setType(vnd.android.cursor.dir/track);
this.startActivity(intent);
I uninstalled Music Bata and the application again worked fine.
Wanted to see if this was a bug related to new Google music
application and see if anyone else was having this problem.

[android-developers] Re: Strategy to implelment various themes?
You can read what theme the user has selected from preference and then set it before the setContentView() method with setTheme(). However you cannot change it on the fly in android, so you need to restart the app for the new theme to kick in.

Re: [android-developers] Does new Google Music Beta support end user selection of songs via intents
Try MediaStore.Audio.Media.CONTENT_TYPE instead, which maps to
vnd.android.cursor.dir/audio. The MIME type you are using is
undocumented.

Re: [android-developers] Intent fails to grab image on certain devices
Write your own image selector using the MediaStore content provider.

[android-developers] Three-level ExpandableListView possible?
I was wondering if there is a way to make a three-level ExpandableListView? I successfully made a two-level ExpandableListView with the help of a tutorial (http://developer.android.com/resources/samples/ApiDemos/src/ com/example/android/apis/view/ExpandableList1.html) But what I want to do is to display an object SystemPlatform which contains an array of sub-objects Game. The sub-objects Game also each can contain sub-objects Cheat. So I want to display all three levels in an ExpandableListView. First only displaying the names of the SystemPlatform objects. When clicking on a SystemPlatform the Game sub-objects will be displayed. If clicked on a Game then the Cheat objects will be expanded. Basically I don't have a two-level list (group children) but a three- level list (group child-groups children). Any way how I could do such a thing?

[android-developers] Re: EditText stops displaying characters as I'm typing?
I have run into this as well. The edit text will accept entry without issue, then it just stops displaying the text entered, but it is there because the getText will find it. EditText android:id=@+id/inputText android:layout_width=fill_parent android:layout_height=wrap_content android:layout_weight=1 android:inputType=textMultiLine / Like you, I originally had the requestFocus / property set, but had to get rid of it as it seemed to be causing other issues. This error occurs both with and without that attribute. Like your code above, I get the text and set it to an empty string when finished. I use an EditText.OnKeyListener and perform my work on KeyEvent.KEYCODE_ENTER and KeyEvent.KEYCODE_DPAD_CENTER, however. I haven't seen this behavior on an emulator, but I have seen it on an LG device. Web searches seem to indicate that it might occur on Samsung devices as well and some of my customers have reported it in market comments (so I don't know what devices they are using) so I don't think it is a device specific bug But who knows. Hopefully someone has some insight. Best Regards, Eric -- You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] Gallery question: loading the current image from a context menu to wallpaper
I'm looking at the Gallery example from the Android-sdk samples (android-7/ApiDemos/src//view/Gallery1.java), and am trying to load the currently-displayed image, from the long-press context menu, as wallpaper. In that example, I have the index number within the array of R.drawable.filename values (i.e., for mImageIds[position], I have position, but what I need, is the value of mImageIds[position]. Is there a way to query the Gallery code for the resource value for the current image? I've looked, and I've been trying to do this for days, and have gotten nothing but one error after another, where correcting one error causes another, for which the correction is to reverse the correction for the first error (that, or declare variables that change constantly to static and/or final). How would I go about this?

[android-developers] facebook

import android.content.Intent;
import android.os.Bundle;
import com.facebook.android.*;
import com.facebook.android.Facebook.*;

});
}
@Override
public void onActivityResult(int requestCode, int resultCode,
Intent data) {
super.onActivityResult(requestCode, resultCode, data);
facebook.authorizeCallback(requestCode, resultCode, data);
}
}
Do I need to put the API key or the app secret anywhere to make this
work?
Thanks.

Simply question: Does the problem happen if you remove your editor action listener? On May 30, 4:21 am, Eric Carman ewcarma...@gmail.com wrote: I have run into this as well. The edit text will accept entry without issue, then it just stops displaying the text entered, but it is there because the getText will find it.

This error occurs both with and without that attribute. Like your code above, I get the text and set it to an empty string when finished. I use an EditText.OnKeyListener and perform my work on KeyEvent.KEYCODE_ENTER and KeyEvent.KEYCODE_DPAD_CENTER, however. I haven't seen this behavior on an emulator, but I have seen it on an LG device. Web searches seem to indicate that it might occur on Samsung devices as well and some of my customers have reported it in market comments (so I don't know what devices they are using) so I don't think it is a device specific bug But who knows.

[android-developers] Re: NFC send Photo
Android does support peer-to-peer wifi network, what exactly are you talking about? I suspect you mean something somewhat different. Ad hoc access points? You wouldn't want to do that anyway -- it would kill the user's active WiFi connection, and this isn't even remotely a legitimate application for ad hoc access points. (I'm not saying you couldn't establish one as a fallback - ad hoc networks are an ad hoc way of establishing connectivity when there's no regular access point. But that's at a lower level than an application; ad hoc networking is not an application-level feature). Peer-to-peer when not on the same subnet? That is entirely out of Android's hands; it can work, but you shouldn't expect it. If they're on the same subnet and can see each other (which depends on WiFi router configuration, *not* the Android), then you can communicate directly. If not, then try Bluetooth, otherwise, do what Bump appears to do -- send it via an intermediary server, which you can even do over 3G if there's no WiFi. If all else fails, you could display a 2D bar code on the sender's screen and let the receiver pick that up, and queue up the send and receive for later. But no, I'm not saying NFC would not be good for any particular application. I'm saying consider the limitations and see if it's a fit. A Bump-type comm would seem to me to be a good fit. Photo sync would in most cases not be, IMHO. A comm between a camera and a photo frame might be. But since NFC is not universally available, I'd currently consider it to be optional, and give development priority to Bluetooth and WiFi. But since it sets up quickly, once implemented, I'd try it first! Actually, I'd try to do the setup for the different transfer modes in parallel. Still you make a good point about it being easier than Bluetooth.

[android-developers] Re: NFC send Photo
By peer-to-peer WIFI I meant that there is no router. I am no networking expert (as you can tell), so my terminology is probably off. An intermediary server in my case is not an option due to the sensitive nature of my custumers' financial data, so it needs to be some sort of peer-to-peer communincation. I wonder if those stickers Google promised to retrofit phones for Google Wallet would be usuable for general purpose NFC applications.

[android-developers] Re: NFC send Photo
Don't worry about the terminology -- ad hoc wifi network is what you're looking for. I just wanted to figure out what you intended to say. Hmm, peer-to-peer and sensitive financial data has me a bit concerned. I don't advocate sending sensitive data, via servers or not, unencrypted. I hope you're using some sort of public key encryption, with a secure key exchange, such as Diffie-Hellman. If all I have to do is eavesdrop on your NFC communications (The role of the public key encryption part is to give you a way to strongly identify the recipient you're exchanging the encryption keys with). And recognize that phones can be lost or stolen; that poses an upper limit of how secure they are. In fact, ideally, really sensitive data wouldn't be stored on the phone at all. Seriously, I would not consider an intermediate server to be a security issue in the slightest. The reason is -- you should always assume that the communication itself can be intercepted. If you don't store it on a server temporarily -- the attacker may, so that he can attack it at leisure, with as much computer power as he wants. (That assumes it's only on the server for a short time, as part of the communication process. If you store large amounts of secure communications long-term, you become a whole different type of target). -- You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] How do you deal with skins clashing with your UI?
I've run into a problem on Motoblur I am not exactly sure how to solve. I have a TextView that I want to look like a Spinner. I can set the theme to android:Widget.Spinner, no problem, but the TextView insits on messing around with the text color unless one is specifically set. So I am giving it the normal Spinner text color, which is textColorPrimaryInverse. The problem is that Motorola decide to customize the Spinner theme so they actually us textColorPrimary (or similar) as the spinner text color. Now, me setting it to textColorPrimaryInverse gives a black text on dark background look which is, obviously, not too good for readability. So my question is: 1) How could I force TextView not to screw around with the color? 2) If that's not possible, how can I detect the presence of Motoblur and set the text color conditionally? -- You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] Moving from free app to a paid model
Hi there, So I started working with Android a while back and have an app on the market (which I pertty much wrote for myself) that surprisingly got a great response, especially from abroad. I'm wondering if any of you ever had to take something from free/hobby-focused to a paid model. I'm curious about the technical details, like how to a) organize the package/app names to differentiate the two, because I want the free paid one available at the same time, and b) some good advice on moving my few but loyal users over without forcing them to download a new app entirely.

[android-developers] Re: Moving from free app to a paid model
They will HAVE to download a new app. Each app is different and there is no way of making a previously free app paid. So you will need to change the package name and package name = app. Personally, I just appended a p after my non-paid app name to create the new package name. Coincidentally, just a couple of weeks ago, as an experiment, I stopped publishing my free app completely and instead am offering a 72- hour money back guarantee. My sales have noticably increased and the refund rate is less than 5% so it may have been a good move -- time will tell.

Well, I am just throwing idea out there. I haven't decided on NFC or that it would use encryption -- it might based on your feedback. I just won't be going the centralized server route, that's I am 100% certain about. Salary information is sensitive enough in the Western world, but if you ever drive around in a taxi in Beijing, don't be surprised if the driver will ask you hold old you are, if you are married and how much money you make.

Re: [android-developers] Re: NFC send Photo
Note that using HTTPS does not give you end-to-end security in this scenario. The server is a man-in-the-middle. It's not a surreptitious one, but it is a man-in-the-middle nonetheless. The cert only serves to ensure it's the *right* man in the middle. So you'll still want to encrypt the payload when using a server this way, unless you're going to make the server a trusted partner. And -- for liability reasons, if nothing else -- you'd like to avoid that unless it's essential to the service being provided. A secure key exchange requires at least a pair of bidirectional messages. You're going to have to do that as well. Basically, to communicate securely any untrusted channel, you'll have to do something like what TLS does under HTTPS -- verification of the identity of the other end of the exchange, secure key exchange, and subsequent encryption. You also have to pay attention to key lifetimes, etc. HTTPS between you and the server really isn't buying you much toward end-to-end security. Having the server handle authentication does simplify the picture in various ways. And a secure server in the middle can let you address various security issues with mobile devices, like revoking access more strongly than is possible with certificate revocation lists. There are no simple answers in security. Everything ends up being complicated.

[android-developers] Re: NFC send Photo
Yes, I understand it varies by culture. Here (US), it's exacerbated by a lot of factors with how we handle credit, jobs, etc., but we also have a moderate expectation of privacy. (The Europeans are stronger on it, at least in terms of what laws are on the books. I think our attitudes and our laws don't exactly match up). I generally advocate designing for a multi-cultural world, and this suggests designing privacy and security for the most restrictive cultures. Anyway, I hope the discussion was useful for you. I think it may have been more useful for other readers.
