Roberto De Simone updated CB-11304:
-----------------------------------
Description:
Use the backbutton to suspend (exit) the app. When later resuming the app -
through the app list or by selecting the app icon - the app loads again but
without splash screen. When the JS is heavy, like an Ionic 2 app there is a
white screen for several seconds which looks very ugly.
This can be reproduced with the simplest possible Cordova app.
1. cordova create test com.mydomain.test test
2. cd test
3. cordova add platform android
4. cordova run android (on a device)
5. Press the backbutton
6. Switch to app list
7. Select the app
-> for a very short time a white screen is visible - the time needed to load
the JS. As the simplest app has very little JS, the effect is difficult to see
on fast devices like a Nexus 6p. If you add heavy JS - like Ionic 2, then the
effect is very well visible also on fast devices.
(Also to mention: the effect is the same when listening to the "backbutton"
event and trying to exit the app with "navigator.app.exitApp() ")
was:
Using the backbutton to suspend (exit) the app, something is going wrongly.
When later resuming the app - through the app list or by selecting the app icon
- the app loads again but without splash screen. When the JS is heavy, like an
Ionic 2 app there is a white screen for several seconds which looks very ugly.
When leaving the app with the hardware "home" button, the app suspends
correctly.
This can be reproduced with the simplest possible Cordova app.
1. cordova create test com.mydomain.test test
2. cd test
3. cordova add platform android
4. cordova run android (on a device)
5. Press the backbutton
6. Switch to app list
7. Select the app
-> for a very short time a white screen is visible - the time needed to load
the JS. As the simplest app has very little JS, the effect is difficult to see
on fast devices like a Nexus 6p. If you add heavy JS - like Ionic 2, then the
effect is very well visible also on fast devices.
8. Now, select the "home" button
9. Switch to app list
10. Select the app
-> the app resumes without loading the JS again - no white screen.
(Also to mention: the effect is the same when listening to the "backbutton"
event and trying to exit the app with "navigator.app.exitApp() ")
> White screen after relaunch when left with back button -> no splashscreen
