16/2/2013 - PPV360HD version prior to 1.1.2 has been discontinued
Please upgrade to the new 1.1.2 version.
One of the major problem about PPV360HD is that it uses everything you have on your tablet/smartphone:
PPV360HD is a cross-platform viewer and currently there are experimentals version that runs on iPhone/iPad iOS, Mac OSx and Windows platform. We hope to release public version very soon.
But Android developers (and so the Android version of PPV360HD) suffer for the fragmentation problem: the many versions of implementation makes really impossible to create an issue-free app. Version are different because:
Some numbers: an inquiry of OpenSignal ( http://opensignal.com/reports/fragmentation-2013/ ) show that in the 2013 there are reported 11868 different type of Android devices; you can imagine what a difficult (impossible) task is to try manage different issues of each device.
Before put a negative rating on the app, take a moment to let us know about the issue,
We will try to fix it as soon as possible.
If you encounter a problem or strange behavior, please let us know using the in-mail functionality in PPV360HD (? menu, "improve" button).
Remember about panic keys: press BACK buttons for times and app will always exit immidiatly.
This list reports already known bugs, that will be fixed in the next releases.
If you have problems launching the app (app doesn't start, crash displaying anything ,ect.), please try the following steps:
Dialog may hang changing image projection.
Some jpeg cannot be loaded, generally small-sized ones.
A generic "jpeg corrupted?" is displayed.
We're addressing this issue and a new release will be available soon.
JPeg progressive images are not supported by PPV360HD, so use some image elaboration software (like GIMP) to save jpeg into a non-progressive type, and try to reload on PPV again.
Really isn't so: app starts but is stuble in a waiting state.
Please remove all .cdf files in the MPGLGE directory, and then start the app again.
On some devices, the 3d world-logo image is showed white.
Seems to be a device-related issue.
Please let us know your device model and brand.
Firefox App doesn't start PPV360HD on jpeg/xmlppv file touch.
More than a bug of PPV360HD is an incompatibility of FireFox with the Android system.
Some users reported that panorama images cannot be viewed until a dialog will put in front. This behaviour are still under investigation, ad appears to be related to the fragmentation problem of the Android platform: many manufactures change some basic UI elements broking the android code that PPV360HD is based on. So it's very hard to understand what the real issue is under the hood.
Due to the high RAM consumption (used for opengl texture images) it's not an easy task to enter and exit from the background.
If you exit without the BACK button, the app may still remains frozen in the background.
If you then lunch it again, probably PPV360HD will crash.
You may use some task manager to Kill PPV360HD and then restart it.
Please exit with the BACK key. We're working about this.
> PPV360HD cannot handle correctly progressive jpeg.
So please use your image editor and re-compress the image turning off this option.
This issue will be fixed in the next 1.1.3 version.
[Thank you Michael Schmitz for investigate this issue]
> Check if jpeg is a standard jpeg 24bit.
Currently I'm using libjpeg implementation, and I found in one case a jpeg image that could not be opened on Android, but the same can be open correctly on Windows. So it seems a platform related issue in our implementation.
We've made a fix for this issue. It will be released in the next 1.1.3 version.
When app starts for the first time, it needs to download GUI resources (menu, icons, etc) optimized for your device display resolution and DPI.
Generally, when you download and install an app it contains all GUI elements for all display resolution, with a waste of internal device storage, bandwidth and mobile data plan.
PPV360HD take in count of this and, after installation, detect your device display resolution and download only the GUI optimized for your display.
After that, no further internet connection is required.
Sometimes, due to high site traffic (or your slow internet connection), resources cannot be downloaded and PPV360HD show you a message:

How to resolve?
Please try this procedure more and more times, the slow download could depend on many factors.
When you browse a pano images, PPV360HD continuosly reads data from storage to make possibile a very high quality viewing experience. Doing so, memory could be not enough and, before PPV360HD recognises a Low Memory Condition and takes the appropiate actions, Android OS decides, without any advice, to kill the app. And you will see the app closing unexpectedly.
To avoid this situation PPV360HD use an advanced component called "Smart RAM Manager", but something can go wrong. You can always monitor an index showing the probability of an imminent crash in the upper left corner of the display, with colored bars indicating the overall app status.
This index is called "Stress Index" and when it's becomes too low (colored orange and red), a crash is imminent.
Generally the bar tends to grow after few seconds, retriving its normal aspect (green).
Enable sending anonymous information. In this way, we will be advised about these errors.
Usually crashes derived from OpenGL MEMORY related problems, or on low memory conditions.
Try the following settings to use few memory:
Check if exist:
Try to download this sampling image:
you have two ways to do this:
After first time pre-processing, the image will be found in the Private Gallery, for further opening.
For subsequent views, this pre-processing step is not needed so the opening can be very fast.
However, performance may vary depending on sdcard write/read speed, from different devices and can be different for the same device from different branding.
In the following table I summarize some performance.
These times do not consider the download time, which depends on the type of internet connection available and may vary on the same device, depending of device free memory, sdcard read/write speed, other active device services, and so on..
Check for enough free space on your sdcard, where the folder MPGLGE/PPV360HD-P? exists.
