  • Phonegap/Cordova orientation change Android 4

    - by user1477576
    I have a problem changing the orientation of the device (Android 4). In other versions it works fine. Versión of Cordova: cordova-1.8.0.js / cordova-1.8.1.js In Android 4 the app crash or show: "A network error occurred. (file:///android_asset/www/index.html)" I searched a lot about this and no answer solves the problem. In most cases users suggest adding: android:configChanges="orientation|keyboardHidden|screenSize" In other cases: super.setIntegerProperty("loadUrlTimeoutValue",60000); That not work for me :( My manifest activity: <activity android:name=".AppNameActivity" android:label="@string/app_name" android:configChanges="orientation|keyboardHidden|screenSize"> <intent-filter> <action android:name="android.intent.action.MAIN" /> <category android:name="android.intent.category.LAUNCHER" /> </intent-filter> </activity> The application should run on Android 2.2 to 4. Thank you very much for the help.

  • After interruption, delayed audio route change notifications when recording

    - by Frank Shearar
    My iPhone application requires that I know when a user has/has not plugged in her headphones. That's easy. AudioSessionAddPropertyListener with a callback listening to kAudioSessionProperty_AudioRouteChange. I write logs with NSLog as things happen. User plugs the headphones in? Get a notification, and a line in the gdb console. User unplugs the headphones? Ditto. At the same time I'm sensing the noise level of the environment by starting a recording audio queue. This, too, works great: I can get the mic noise level and listen for audio route changes just fine. What I find is that after an interruption, and I've reactivated the audio session and restored the audio category to kAudioSessionCategory_RecordAudio, the audio route notifications go a bit haywire. When I plug in the headphones, I see no notification. When I unplug the headphones I see BOTH the "plugged in" notification AND the "unplugged" notification, in rapid succession. It's like the "plugged in" notification's delayed and, when the "unplugged" notification arrives, the queue of pending notifications is flushed. What am I doing wrong? How do I correctly restore the audio session to get timeous notifications? EDIT: iPhone OS 3.1.2, running on an iPhone 3G. I'm running a program compiled with the 3.0 SDK (from within XCode 3.1.2).

    - by Sergio Tapia
    Hi there, first time posting in StackOverflow. :D I need my software to add a couple of things in the registry. My program will use Process.Start(@"blblabla.smc"); to launch a file, but the problem is that most likely the user will not have a program set as default application for the particular file extension. How can I add file associations to the WindowsRegistry?

  • How to change a Window Owner using its handle

    - by Ricky AH
    I want to make a .NET Form as a TopMost Form for another external App (not .NET related, pure Win32) so it stays above that Win32App, but not the rest of the apps running. I Have the handle of the Win32App (provided by the Win32App itself), and I've tried Win32 SetParent() function, via P/Invoke in C#, but then my .NET Form gets confined into the Win32App and that's not what I want.

  • MessageBox.Show-- font change?

    - by mmr
    Hi all, I'm using the MessageBox class to show errors to users, and while that might not be the right behavior, it's very convenient. This is a touchscreen application, however, so I need the 'ok' button to be much larger than it is (curse my inordinately large fingers!). I think that if I increase the font size in the dialog box, I should be ok. Is there a way to do that? Or really, is there any way to increase the dialog size? Thanks
