|
|
|
|
#### Version 0.2.0 (08.10.2013)
|
|
- Added iOS (>= 5) support<br>
|
|
The plugin turns the app into an location tracking app for the time it runs in the background.
|
|
|
|
## Using the plugin
|
|
Simply add the plugin to your project and the app will run while in background.
|
|
|
|
The plugin creates the object ```window.plugin.backgroundMode``` with two methods:
|
|
|
|
### enable()
|
|
The method enables the background mode. The mode is activated once the app has entered the background and will be deactivated after the app has entered the foreground.<br>
|
|
Please be aware, to activate the background mode the app needs to be in foreground.
|
|
|
|
```javascript
|
|
/**
|
|
* Enables the background mode. The app will not pause while in background.
|
|
*/
|
|
window.plugin.backgroundMode.enable();
|
|
```
|
|
|
|
### disable()
|
|
The method disables the background mode. If the mode is disabled while the app is running in the background, the app will be paused immediately.
|
|
```javascript
|
|
/**
|
|
* Disables the background mode. The app will pause in background as usual.
|
|
*/
|
|
window.plugin.backgroundMode.disable();
|
|
```
|
|
|
|
## Quirks
|
|
|
|
### The app crashes under iOS
|
|
If the app crashes after installing the plugin, make sure that your `*-Info.plist` is valid.
|
|
Do to some bugs in cordova or Plugman please reset all occurences like
|
|
```xml
|
|
<key>NSMainNibFile</key>
|
|
<string>
|
|
|
|
</string>
|
|
```
|
|
to
|
|
```xml
|
|
<key>NSMainNibFile</key>
|
|
<string></string>
|
|
```
|
|
|
|
### Location tracking under iOS
|
|
**iOS 5-6**<br>
|
|
The app still runs in background, even if the location service is not actived.
|
|
|
|
**iOS 7**<br>
|
|
The location service needs to be enabled.
|
|
|
|
### Optimization under WP8
|
|
By default the plugin will track for geo updates while the application is in background and foreground. To stop tracking in foreground, the `MainPage.xaml.cs` file needs the following 2 methods:
|
|
```c#
|
|
namespace your.own.namespace
|
|
{
|
|
public partial class MainPage : PhoneApplicationPage
|
|
{
|
|
/// </summary>
|
|
/// The page (the app) will enter the background and the background mode
|
|
/// needs to be activated.
|
|
/// </summary>
|
|
protected override void OnNavigatingFrom(System.Windows.Navigation.NavigatingCancelEventArgs e)
|
|
{
|
|
Cordova.Extension.Commands.BackgroundMode.Activate();
|
|
}
|
|
|
|
/// </summary>
|
|
/// The page (the app) will enter the foreground and the background mode
|
|
/// needs to be deactivated.
|
|
/// </summary>
|
|
protected override void OnNavigatedTo(System.Windows.Navigation.NavigationEventArgs e)
|
|
{
|
|
Cordova.Extension.Commands.BackgroundMode.Deactivate();
|
|
}
|
|
}
|
|
}
|
|
```
