  • Help with why my app crashed?

    - by Moshe
    I'm writing an iPad app that is a "kiosk" app. The iPad should be hanging on the wall and the app should just run. I did a test, starting the app last night (Friday, December 31) and letting it run. This morning, when I woke up, it was not running. I just checked the iPad's console and I can't figure out why it crashed. The iPad was plugged in and so the battery is not the issued. I did disable the idleTimer in my application delegate. The app was seen running as late as midnight last night. I would like to note that my app acts as a Bluetooth server through Game Kit and large portion of the console output is occupied by bluetooth status messages. When I opened the iPad, the app was paused and there was a system alert which prompted me to check an "Expiring Provisioning Profile". I tapped "dismiss" and the alert went away. The app crashed about a second after I dismissed the system alert. Any ideas how I can diagnose this problem? Why would my app crash? Here is my iPad's Console log, as copied from Xcode's organizer. Edit: A bit of Googling lead me to this site which says that alert views cause the app to lose focus. Could that be involved? What can I do to fix the problem? EDIT2: My Crash log describes the situation as: Application Specific Information: appname failed to resume in time Elapsed total CPU time (seconds): 10.010 (user 8.070, system 1.940), 100% CPU Elapsed application CPU time (seconds): 9.470, 95% CPU

  • Google App Engine - Document Editor Creation/Tap Into Google Docs?

    - by Josh Patton
    What is the best way to create a custom document editor in GAE? I'm making a website meant for a School Robotics Club (With support for any other organization - DRY). We currently use Google services for online collaboration, I'm wondering if there is a way to tap into Google Docs and allow users to edit a Google Document without using Google Accounts or the Google Doc interface. If that is not possible (I've researched and I don't think it is), what is the best way to make a document editor? I want it completely on the website I'm creating, so I'm assuming just some javascript editor like TinyMCE + Ajax + Datastore. Is their anything that replicates Google Doc's/Microsoft Offices's/OpenOffice.org's feature set as far as fonts, spacing, alignment, justification, etc.?

  • android app crashes if keyboard was shown

    - by Jaume
    I have an activity that I force keyboard to appears using, InputMethodManager inputMethodManager=(InputMethodManager)getSystemService(Context.INPUT_METHOD_SERVICE); inputMethodManager.toggleSoftInput(InputMethodManager.SHOW_FORCED, 0); keyboard appears properly and also obscured when needed. Problem is when I finish the activity, app crashes. If the activity never shows keyboard or shows it without start editing text, it is finished with no errors but if you just write one single character or more, app will crash. How to solve it? thank you. method used to finish activity, boto_back.setOnClickListener(new OnClickListener() { @Override public void onClick(View arg0) { InputMethodManager inputMethodManager=(InputMethodManager)getSystemService(Context.INPUT_METHOD_SERVICE); inputMethodManager.toggleSoftInput(InputMethodManager.HIDE_IMPLICIT_ONLY, 0); finish(); } }); @Override public void onDestroy() { if (adMob != null) { // Destroy the AdView. adMob.destroy(); } super.onDestroy(); } logcat, 07-07 19:04:25.191: E/AndroidRuntime(8443): FATAL EXCEPTION: main 07-07 19:04:25.191: E/AndroidRuntime(8443): java.lang.RuntimeException: Unable to destroy activity {com.xxxx.xxxx/com.xxxx.projecte1.TabBar_iOSActivity}: java.lang.RuntimeException: Unable to destroy activity {com.xxxx.xxxx/com.xxxx.projecte1.webPush}: java.lang.NullPointerException 07-07 19:04:25.191: E/AndroidRuntime(8443): at android.app.ActivityThread.performDestroyActivity(ActivityThread.java:2693) 07-07 19:04:25.191: E/AndroidRuntime(8443): at android.app.ActivityThread.handleDestroyActivity(ActivityThread.java:2711) 07-07 19:04:25.191: E/AndroidRuntime(8443): at android.app.ActivityThread.access$2100(ActivityThread.java:121) 07-07 19:04:25.191: E/AndroidRuntime(8443): at android.app.ActivityThread$H.handleMessage(ActivityThread.java:976) 07-07 19:04:25.191: E/AndroidRuntime(8443): at android.os.Handler.dispatchMessage(Handler.java:99) 07-07 19:04:25.191: E/AndroidRuntime(8443): at android.os.Looper.loop(Looper.java:130) 07-07 19:04:25.191: E/AndroidRuntime(8443): at android.app.ActivityThread.main(ActivityThread.java:3701) 07-07 19:04:25.191: E/AndroidRuntime(8443): at java.lang.reflect.Method.invokeNative(Native Method) 07-07 19:04:25.191: E/AndroidRuntime(8443): at java.lang.reflect.Method.invoke(Method.java:507) 07-07 19:04:25.191: E/AndroidRuntime(8443): at com.android.internal.os.ZygoteInit$MethodAndArgsCaller.run(ZygoteInit.java:866) 07-07 19:04:25.191: E/AndroidRuntime(8443): at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:624) 07-07 19:04:25.191: E/AndroidRuntime(8443): at dalvik.system.NativeStart.main(Native Method) 07-07 19:04:25.191: E/AndroidRuntime(8443): Caused by: java.lang.RuntimeException: Unable to destroy activity {com.xxxx.xxxx/com.xxxx.projecte1.webPush}: java.lang.NullPointerException 07-07 19:04:25.191: E/AndroidRuntime(8443): at android.app.ActivityThread.performDestroyActivity(ActivityThread.java:2693) 07-07 19:04:25.191: E/AndroidRuntime(8443): at android.app.ActivityThread.performDestroyActivity(ActivityThread.java:2603) 07-07 19:04:25.191: E/AndroidRuntime(8443): at android.app.LocalActivityManager.dispatchDestroy(LocalActivityManager.java:622) 07-07 19:04:25.191: E/AndroidRuntime(8443): at android.app.ActivityGroup.onDestroy(ActivityGroup.java:85) 07-07 19:04:25.191: E/AndroidRuntime(8443): at com.xxxx.projecte1.TabBar_iOSActivity.onDestroy(TabBar_iOSActivity.java:417) 07-07 19:04:25.191: E/AndroidRuntime(8443): at android.app.ActivityThread.performDestroyActivity(ActivityThread.java:2680) 07-07 19:04:25.191: E/AndroidRuntime(8443): ... 11 more

  • How to get to the key name of a referenced entity property from an entity instance without a datastore read in google app engine?

    - by Sumeet Pareek
    Consider I have the following models - class Team(db.Model): # say I have just 5 teams name = db.StringProperty() class Player(db.Model): # say I have thousands of players name = db.StringProperty() team = db.ReferenceProperty(Team, collection_name="player_set") Key name for each Team entity = 'team_' , and for each Player entity = 'player_' By some prior arrangement I have a Team entity's (key_name, name) mapping available to me. For example (team_01, United States Of America), (team_02, Russia) etc I have to show all the players and their teams on a page. One way of doing this would be - players = Player.all().fetch(1000) # This is 1 DB read for player in players: # This will iterate 1000 times self.response.out.write(player.name) # This is obviously not a DB read self.response.out.write(player.team.name) #This is a total of 1x1000 = 1000 DB reads That is a 1001 DB reads for a silly thing. The interesting part is that when I do a db.to_dict() on players, it shows that for every player in that list there is 'name' of the player and there is the 'key_name' of the team available too. So how can I do the below ?? players = Player.all().fetch(1000) # This is 1 DB read for player in players: # This will iterate 1000 times self.response.out.write(player.name) # This is obviously not a DB read self.response.out.write(team_list[player.<SOME WAY OF GETTING TEAM KEY NAME>]) # Here 'team_list' already has (key_name, name) for all 5 teams I have been struggling with this for a long time. Have read every available documentation. I could just hug the person that can help me here :-) Disclaimer: The above problem description is not a real scenario. It is a simplified arrangement that represents my problem exactly. I have run into it in a rater complex and big GAE appication.

  • What are the restrictions for the name of an application when submitting to App Store ?

    - by Patrick
    Hello, I have just finished my application for iPhone. I would like to know if it is possible to use the word iPhone in the name of the application. For example, can I name my application iPhonesque ? And for the icon, can I use graphics related to Apple like a Mac Windows (with the three buttons, red, yellow and green) on snow leopard background ? Thank you very much for your answers.

  • Using CookieJar in Python to log in to a website from "Google App Engine". What's wrong here?

    - by brilliant
    Hello everybody, I've been trying to find a python code that would log in to my mail box on yahoo.com from "Google App Engine" . Here (click here to see that page) I was given this code: import urllib, urllib2, cookielib url = "https://login.yahoo.com/config/login?" form_data = {'login' : 'my-login-here', 'passwd' : 'my-password-here'} jar = cookielib.CookieJar() opener = urllib2.build_opener(urllib2.HTTPCookieProcessor(jar)) form_data = urllib.urlencode(form_data) # data returned from this pages contains redirection resp = opener.open(url, form_data) # yahoo redirects to http://my.yahoo.com, so lets go there instead resp = opener.open('http://mail.yahoo.com') print resp.read() The author of this script looked into HTML script of yahoo log-in form and came up with this script. That log-in form contains two fields, one for users' Yahoo! ID and another one is for users' password. Here is how HTML code of that page for both of those fields looks like: User ID field: <input type="text" maxlength="96" class="yreg_ipt" size="17" value="" id="username" name="login"> Password field: <input type="password" maxlength="64" class="yreg_ipt" size="17" value="" id="passwd" name="passwd"> However, when I uploaded this code to Google App Engine I discovered that this log-in form keeps coming back to me, which, I assume, means that logging-in process didn't succeed. Why is it so?

  • Google Jam 2009. C. Welcome to Code Jam. Can't understand Dynamic programming

    - by vibneiro
    The original link of the problem is here: https://code.google.com/codejam/contest/90101/dashboard#s=p2&a=2 In simple words we need to find how many times the string S="welcome to code jam" appears as a sub-sequence of given string S, e.g. S="welcome to code jam" T="wweellccoommee to code qps jam" I know the theory but not good at DP in practice. Would you please explain step-by-step process to solve this DP problem on example and why it works?
