content and again start 1st.
I need whenever user click next it will up to 5th content and same to
previous when user click back it will show up tp 1st content.
You can put a check something like this.
if(viewflipperinstance.getDisplayedChild()!=0)
{
viewflipperinstance.showPrevious()
}
or
if(viewflipperinstance.getDisplayedChild()!=(viewflipperinstance.getChildCount()-1)
{
viewflipperinstance.showNext()
}
This will help you out.

[android-developers] Re: detect if an app is launched
The platform deliberately does not provide easy mechanisms to do this, because monitoring what the user is doing is not something to encourage. If someone wants to do it for 'bad' reasons, they're not going to be discouraged by a little extra time and extra resource usage of having to poll for it! Not providing an event for this just penalizes devs/users with a 'legitimate' need for the info. You haven't said why you want to do this, but I would discourage you from whatever path you are going down here. Users like to do different things depending on which app they are using (different screen brightness, timeout, turn on/off wifi for Internet etc). Automation apps are reduced to battery-expensive polling to provide this currently. Pent -- You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] Re: Customized Soft keyboard
Have a look at
KeyboardViewhttps://developer.android.com/reference/android/inputmethodservice/KeyboardView.html.
You define the keyboard using a XML file like this:
Keyboard xmlns:android=http://schemas.android.com/apk/res/android;
android:keyHeight=50dp
android:keyWidth=16.66%p
Row
Key
android:codes=8
android:keyLabel=1 /
...
Then, in code, all you need to do is set the keyboard and set a keyboard
listener to handle key presses.
If you manage to get the right keycodes for all keys, then you only need to
implement this part to make it work:
protected class KeyboardListener implements OnKeyboardActionListener {
@Override
public void onKey(int primaryCode, int[] keyCodes) {
long eventTime = System.currentTimeMillis();
KeyEvent event = new KeyEvent(eventTime, eventTime,
KeyEvent.ACTION_DOWN, primaryCode, 0, 0, 0, 0,
KeyEvent.FLAG_SOFT_KEYBOARD |
KeyEvent.FLAG_KEEP_TOUCH_MODE);
getActivity().dispatchKeyEvent(event);
}
...
}

InputStream is= socket.getInputStream();
DataInputStream inChannel= new DataInputStream(new BufferedInputStream(in));
ByteArrayOutputStream baos = new ByteArrayOutputStream();
int oneByte;
while ((oneByte = inChannel.read()) != -1) {
if (oneByte == 0) {
break;
}
baos.write(oneByte);
byteCount++;
}
byte[] inData = baos.toByteArray();
baos.close();

[android-developers] Wifi Power consumption optimisation
I want to write an application which will gather data from user and send them to router using wifi for example once in every minute (there will not be plenty of data rather 1kb in every minute but it is critical to send them quite frequently). My question is: How to optimize wifi usage? Should I switch it on and off every time when I'm using it? Or is there some sleeping mode (when wifi is switched off but after switching on it connect to network immediately without searching for ip etc.) Does it depend on android version? Is Android 2.2 ok, or do i need higher version (which one?) Thank you in advance. Adam -- You received this message because you are subscribed to the Google Groups Android Developers group.

Re: [android-developers] Re: Resolution Problem in Nexus One
I understand what you saying, but how to solve the following scenario: - You developed an application with English (default), German, and Italian languages; - A French user (whom mobile is in french and have many french applications in the phone) installs you application; - Because your application doesn't have French, android chooses the default one, in this case English, right? - So you application is shown in English, but what if the user just don't speak English but speaks Italian? How can he change this without changing his locale settings from French to Italian?

[android-developers] How to upload apk with new version, when previous key store is lost?
Hi, We have been developing Android apps since a while now but unfortunately *we lost our key store which was used to sign a previously uploaded apk*, now we want to upload a new version of existing live app on Google play to do so we need to sign new apk with different key store but Google Play will not accept apk signed with different key store. Is there any way that we could upload new version of app with different key store as we do not want to add separate new app asap for those user which have already installed previous version and they deserve *to have update existing app rather than purchasing brand new app again?* Also if not possible for above statement then: Is there any way to get complete information of key store from previously signed apk so that we could possibly get key store and use it to upload new version of app? Android Support: Please answer on this situation as there could be some way to upload apk with new version and signed with new key store.

You probably defined the DisplayMessageActivity outside the original application tag in the manifest file. It should go inside the existing application tag.

[android-developers] Generating apk on Windows and OSX
We are in development mode and have: Windows XP SP3 to generate apk_w. Mac OSX 11.x. to generate apk_m. Both apk_w and apk_m are identical but with different certificates - an apk install with different certificate requires that previous apk is uninstalled first instead of overwriting. Min API 7 level. apk_w installs on Nexus (Android 4) and HTC (Android 4) but, doesn't install on Galaxy/II (Android 4) or Galaxy/I (Android 2.2). apk_m installs on Nexus (Android 4), Galaxy/II (Android 4), Galaxy/I (Android 2.2) and HTC (Android 4). After apk_m installs successfully on Nexus (Android 4) and Galaxy/I (Android 2.2), apk_w is re-installed on Nexus and Galaxy/I and this time installs successfully. This was repeated multiple times with the same results.

Re: [android-developers] How to upload apk with new version, when previous key store is lost?
This isn't possible. You cannot sign two versions with different keys. Neither can you recover a key from a signed apk. It is best to keep several backups of your keys. You'll have to upload a fresh app now.

[android-developers] Re: NDEF Message
Hello Shekhar, I am already aware of the fact that a NDEF message can have multiple NDEF records in it and payload data allowed is maximum of 2^32-1 bytes. If I have a payload data of 100 octets which is inside the range of default MIU, in that case should I send the data in one record or in a chunk of records. Which one is preferable and why? You should not bother about record chunks. Devices (or the operating system) are supposed to handle them automatically. So all you do in your app is put the record payload into an NDEF record and the NDEF record into an NDEF message. Suppose a remote device( which is not android ) send the NDEF message in the group of NDEF records then how to extract the payload from it. If a remote device splits the record into multiple chunks, the Android system should join the junks into full records before presenting them to the app. (Although, I have not thested if Android is capable of handling chunked records.) br Michael -- You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] Re: Android NFC Options
Hi Alistair, I'm attempting to get into NFC on Android by communicating with a custom PN532 device, however I'm a little confused as to my options and the Android protocol. - NFCIP-1, is it possible to place my device as a target into this mode, for Android to automatically detect and communicate with to load an app Android's foreground NDEF push/beam is based on NFCIP-1 (+ LLCP), so you can exchange NDEF messages between an Android device and the PN532 in peer-to-peer mode. See http://code.google.com/p/ismb-snep-java/ (or the older http://code.google.com/p/ismb-npp-java/ ) for an example of how to communicate with Android apps in peer-to-peer mode. The ACR122U that is used in this examples contains a PN532, so it should be easy to adapt them to your custom PN532 device. - or can this only be done in card emulation mode (i.e. does NFCIP-1 have to be actively triggered)? You mean that you put your PN532 into card emulation mode and use the Android device as a card reader? This is also possible. You could then, for instance, emulate a type 4 NDEF tag or use your custom ISO-DEP based protocol. - What's the easiest to use card emulation mode for the sake of data format simplicity? (get an NDEF file over to the phone as simple and easy as possible that it will automatically act upon)? If you put the PN532 into card emulation mode and emulate a type 4 NDEF tag (see the NFC Forum website for the specification), the phone will recognize it as any other (real) tag. br Michael -- You received this message because you are subscribed to the Google Groups Android Developers group.

Re: [android-developers] finding which application uses a port on the android device
I am unsure if i understand you question, it may be that programs communicating with a server do not need to identify themselves to a server, they merely send/receive data. While some programs, such as browsers do identify themselves, this is not always true. I would suggest that you practice with a normal server setup, and once you have a method that works you can begin to port that method for your app. Regards, Fred On 24 June 2012 16:51, Ami Turgman ami.turg...@gmail.com wrote: Hi All, I have an android native application which hosts a web server inside it.

[android-developers] Re: does NFC in gingerbread support card simulate?
Hi Shailen, I see that you created the NFCTagInfo App, available on the market. This app is, by far, the best Tag reader, because of all the little information it can give us, for example the HEX/ASCII values of the sectors. Thanks! Anyway, I just wanted to point out that it is possible to simulate an NFC Tag with card emulation. I was able to turn on card emulation on my Samsung Nexus S phone which sports a PN65 (=PN544+SmartMX) chip. The emulated card was a MIFARE 4K, which is a Type 4 NFC Tag. Using another Nexus S and the NXP TagWriter app, I was able to write a plain text message on the card-emulated Nexus S. First of all, you are partly right: The embedded secure element can be enabled with the latest device firmware (or is usually enabled by default to allow Google Wallet to work). Second, you are certainly wrong with MIFARE 4K beeing a Type 4 NFC tag! MIFARE 4K (and so does MIFARE 1K) use a proprietary protocol that is not specified as part of the NFC Forum's NDEF tag specifications. Still, once the embedded secure element is enabled for card emulation the MIFARE 4K area is readable and writable with the default keys. So it could probably be used with *some* NFC devices as NFC tag. Remember, however, that not all NFC devices support MIFARE 1K/4K. Also, this only allows external access to the MIFARE area. Internal access, i.e. through an app on the same phone, is still not easily doable. (It can be done with firmware modifications and it can be done through components installed as part of Google Wallet.) That said, full card-emulation is possible on the Nexus S!! I certainly would not call this *full* card emulation. Especially as you cannot modify the card content from within the phone. br Michael -- You received this message because you are subscribed to the Google Groups Android Developers group.

You can put a check something like this.
if(viewflipperinstance.getDisplayedChild()!=0)
{
viewflipperinstance.showPrevious()
}
or
if(viewflipperinstance.getDisplayedChild()!=(viewflipperinstance.getChildCount()-1)
{
viewflipperinstance.showNext()
}
This will help you out.

Re: [android-developers] detect if an app is launched
Let me clarify you about my requirement. I actually want to monitor all the apps stored in the device, and retrieve their information (like how many times app is opened or closed. All that process of maintaining the record will start, when I first time install my app (which will show me details of other apps). For this reason, I wanted that as soon as any device app (system's app as well as user's apps), is launched or closed, the database should be updated like --- *App A started: 2 times and stopped 1 time total usage: 15 hrs, App B started 3 times stopped: 3 times, total usage: 7 hrs* And in my own application, I can retrieve that information. I wish, my problem is somewhat clear to you. You almost just want to grab the output of dumpsys usagestats but that's restricted to apps with the android.system.DUMP permission installed in /system/app. (I'm guessing that this level of data collection is not evil as Google has the DUMP permission in their proprietary Google Services Framework and Google Account Manager, but I'm not sure why it's discouraged for app developers but ok for google..) I think the DUMP permission changes between Dangerous and SystemOrSignature depending on what Android version you are looking at so you might have to be pre-installed on the device to do it (root/build your own ROM.) If you don't want to poll, you could try a blocking read on logcat -s -v time ActivityManager and parse for the start intents (but you'd still have to go look for application exit in the RunningAppInfo, but you could only do that on ActivityManager messages so you'd only be doing it when the ActivityManager is changing applications.) You'd need the android.permission.READ_LOGS permission to do that. Neither of these are SDK supported, and both cost you an extra process, but the logcat process is pretty light weight, and the dumpsys would only need to be run once at reporting time. In theory the user would is alerted on application installation that you are requesting the dangerous permissions, so you might want to be clear about why you need them in your application description.

Re: [android-developers] Re: How to create a x509 certificate?
You can't create a certificate with the built in Bouncy Castle library. Unfortunately, you can't include the Bouncy Castle JAR in your android app because of a naming conflict. All hope is not lost. Find and use the Spongy Castle JAR. This is identical to Bouncy Castle but with a different package name. You'll be able to create your certificates with this library.
