[android-developers] Re: How trigger intent to execute a specific method from a specific activity
1. Register a BroadcastReceiver that listens for a specific Intent. 2. When the user clicks on the Notification, the PendingIntent will be launched. You can put extra's in this Intent. You can use the extra's to determine which method will be launched in the Service.

Let's keep it simple: I currently have an app that runs with the
system sharedUserId by siging it with the platform key. See also:

trying a new approach: using Runtime and Process to be able to talk to
wpa_cli, the command line interface program for talking to
wpa_supplicant.
When I run wpa_cli from adb shell(as root) I can enter a command
such as 'help'. However, when I start wpa_cli (as system) using
Runtime and Process (and Input- and OutputStreams) in my app and push
the help command to wpa_cli, I don't get anything back.

Hello Jouni,
Thanks for the reply. I've tried talking to the Unix domain Socket,
but it doesn't work. It appears to be a permission problem.
You mentioned that Solution 3 should work.
Quote from my previous post; - Solution 3: Talking directly to the
control interface of wpa_suplicant using Unix domain sockets. I found
that the Android API supplies us with the LocalSocket class for
this. ...
I have tried 2 ways of connecting to the wpa_supplicant Unix domain
socket(s).
1. From an Android terminal emulator through wpa_cli.
2. I adapted an example Java Android program
(original:http://all4dev.blogspot.com/2009/02/android-localsocket-localserverso...).
For clarity: each Android app has its own group and username, for
example group:user = app_35:app_35. For each approach I adjusted
wpa_supplicant.confctrl_interface_group to allow an app access to the
domain sockets, for example (ctrl_interface_group=app_35).
Results approach 1 ( From an Android terminal emulator through
wpa_cli. ):
1. I start up the Android terminal emulator and enter the command
wpa_cli -p/data/misc/wifi/sockets/ctrl_wpa_79-0. I get the message:
Using interface 'tiwlan0'
Could not connect to wpa_supplicant - re-trying
(The output is the same if I don't add the path to the socket, or
change the path to /data/misc/wifi/sockets.)
Results approaches 2a and 2b:
Next, I tried it from an Android Java program (with the correct
wpa_supplicant.conf.ctrl_interface_group and after
wpa_clireconfigure) using 2 slightly different approaches:
a. When I use 'tiwlan0' as LocalSocketAddress, I use an abstract
namespace for the LocalSocket. When I do this I get a 'connection
refused' error message from the Android debug tool logcat.
b. When In use /data/misc/wifi/sockets/ctrl_wpa_79-0, I use the
Filesystem Namespace. I then get a 'permission denied' error message.
ab Both throw an IOException at the line receiver.connect(new
LocalSocketAddress(SOCKET_ADDRESS, NAMESPACE)); (this happens when
if socket is in invalid state or the address does not exist.).
So, or I'm doing something wrong, or something goes wrong with the
socket permissions. In the adb shell output the file permissions for
the sockets are set to group:user system:wifi.
Below this message you can find the shell output and the Java code.
Thanks for any help in advance.
Kind regards,

And I've also tried using the wpa_supplicant.conf file. However, when I use the FileInputStream to read /data/misc/wifi/wpa_supplicant.conf file I get a FileNotFoundException. My app is again running as system user. Apparantly the system user cannot access a wifi-user-secured- directory. The acces permissions are /data(system)/misc(system)/ wifi(wifi). I've also tried android.uid.wifi: This leads to the app running again in it's own sandbox (user id = something like app_20). I've tried to sign this using other certificates as well: shared, media and release. In the AndroidManifest.xml / Android.mk of the Phone app (http:// android.git.kernel.org/?p=platform/packages/apps/ Phone.git;a=tree;hb=abc47110c17fa8e8cb6161bc045e87f31eeb7a1c) we find the combination android.uid.phone / LOCAL_PACKAGE_NAME := Phone. When we use this for our app (android.uid.phone and siging with the platform certificate/key) this leads to a failure when installing: INSTALL_FAILED_UPDATE_INCOMPATIBLE. Apparently something else is at play here too. So, my question: Is it possible to give an app wifi user permissions?

Basically, the program is a simple multiplayer trivia game where the phone is passed from player to player for each turn. Right now, I am storing game state in an object that is accessible in all other classes of the program. I have an activity that successfully retrieves a question, displays it for the current player, and correctly verifies input. Then, how do I change it so that it is the next player's turn? I tried starting a new instance of that same activity, since it could get the new game state from the separate object, but that just causes my program to freeze. Similarly, a while loop inside my activity causes the program to loop infinitely at that spot. I'm sure I just don't quite understand how it all fits together, and I'd appreciate some help. So, to be clear, here are the important parts of my program that I have so far: StartGame - activity that allows you to set up a new game launches PlayGame activity as an intent PlayGame - activity that displays a question and verifies input as an answer. I can only launch it once and display one question. This activity is meant to be re-used to display all the questions, since it gets information on the game state (turns, current question, answer, etc...) from the Game class. Game - object that is statically available to all other parts of the program. It is a singleton, so there will only ever be one instance of it. How should I structure my program so that it can show multiple questions in succession until a certain condition is met (i.e. each player has had 4 turns, or there have been 10 total rounds, etc...)?

Furthermore, only a superuser should know some kind of unlock mechanism to unbrick/unlock the phone again. Rebooting the phone should not diable the blocking / bricking. If you're looking for your app to be invasive to the user, you're unlikely to find it in the public API. Perhaps take a look at how the various lock screen apps work. Thanks for the suggestion. I'll take a look. Kind regards, a2ronus On Fri, Feb 19, 2010 at 9:49 PM, a2ronus aaron.jan...@gmail.com wrote: Hi, (I'm new to posting questions on Google Groups.

[android-developers] Re: Expanding the status bar from an app (android . permission . EXPAND_STATUS_BAR?)
Hello TreKing, Thanks for the reply.

I doubt you can do this and I personally don't think this is good usability. As a user, I want to determine when to expand the status bar, not you. You can post a notification with an alert and vibration to let me know there's something to check, but I will check when I'm good and ready, not when you tell me to. If I had an app that randomly expanded the status bar when I was in the middle of something, I would probably promptly uninstall it. Ok, thanks for the idea. But then I still wonder why this permission can be found in the API. --- -- TreKing - Chicago transit tracking app for Android-powered deviceshttp://sites.google.com/site/rezmobileapps/treking Kind regards, a2ronus -- You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] Expanding the status bar from an app (android . permission . EXPAND_STATUS_BAR?)
Hi all, (I'm new to posting questions on Google Groups. Suggestions on good posting behaviour are appreciated. :) ) Hi, for good usability in an app that I'm developing I would like to expand the status bar to show the user the first time that there is more information to be found on the expanded status bar. (The user will run several apps at the same time, and background services will post notifications. The expanded notifications link back to several the apps/activities that the user is running. ) I've been searching for a while now, but the only thing I could find was: http://developer.android.com/reference/android/Manifest.permission.html#EXPAND_STATUS_BAR. I'm looking for a code example on how to expand the status bar. I hope somebody would be able to enlighten me by providing some answers or pointers on where to look.

[android-developers] Talking to wpa_supplicant for TTLS / PEAP / TLS (Runtime+wpa_cli / JNI / LocalSocket(Unix domain socket) / wpa_supplicant.conf?)
Hi, (I'm new to posting questions on Google Groups. Suggestions on good posting behaviour are appreciated. :) ) This is what I'm trying to achieve: I would like to write an Android app that is capable of talking to wpa_supplicant. More specifically, I would like to connect to a WPA2-EAP secured network (with authentication methods TTLS / PEAP / TLS), but since the device will be used by several users, the user credentials will be supplied by the user in my app, instead of by wpa_suplicant.conf. I don't want to write my own supplicant software, I would like to be able to communicate with it. (I am able to connect to the network when I provide the user credentials as well in the /data/misc/wifi/ wpa_supplicant.conf file) I've looked at several solutions and their problems, and I would like some advice on them. Maybe I've overlooked something: - Solution 1: Using the Android Wifi API. Problem: The Android WiFi API doesn't seem to support TTLS / PEAP / TLS. Strange other thing is: It appears to support LEAP, but I can't find a way to supply the user credentials to the WifiConfiguration. - Solution 2: Letting the app write to /data/misc/wifi/ wpa_supplicant.conf and then reassociating. Problem: I understand from the API that apps can only write to their own private space or the external SD store. I've also tried writing to a file with the Terminal Emulator app. This doesn't work. I can only write wpa_supplicant.conf in the adb shell with root acces. - Solution 3: Talking directly to the control interface of wpa_suplicant using Unix domain sockets. I found that the Android API supplies us with the LocalSocket class for this. However, I have no idea how to cummunicate with the wpa_supplicant control interface domain socket. (I will also post this on a wpa_supplicant forum). - Solution 4: Using java.lang.Runtime and .Process for running wpa_cli and communicating with it. Problem: I expect there will be Manifest.permission conflicts. - Solution 5: Another option might be to use Android NDK / JNI to be able to use the helper functions in c that wpa_supplicant provides. Problem: This might be a solution, but it seems to me that it complicates matters a lot. And I also wonder if there might be some Manifest.permission conflicts. - Solution 6: Finding some open source Java supplicant code and adapting this. Problem: I haven't found it yet. (My C skills aren't so good). I really need some help on this. Is there somebody with some more experience on this topic? I hope somebody would be able to enlighten me by providing some answers or pointers on where to look. Any help would be greatly appreciated.

[android-developers] Code example on possibilities of android . permission . STATUS_BAR?
Hi, The following page seems to imply that it's possible to hide icons on the status bar, but I can't seem to find information or examples that show which icons you can disable, and what is meant by opening or closing the status bar. http://developer.android.com/reference/android/Manifest.permission.html#STATUS_BAR: Allows an application to open, close, or disable the status bar and its icons.. I'm looking for code examples to use this permission. I hope somebody would be able to enlighten me by providing some answers or pointers on where to look.
