Does the installation of different applications on the same device consume the number of signatures?
Signature consumption is the number of signatures required for an application to be installed on a device. When installing an app on a new device, you can check the current signature consumption of this device and know how many signatures are left. There are some cases where you may need to install the same app on different devices but still want to ensure that there’s enough space left in your account for other apps. In this case, there’s no problem as long as both devices have enough space; so here I’ll introduce how we manage these things at MobileSignal:
If the same application is installed on different devices
If the same application is installed on different devices, signature (超级签)consumption is the same. If you install the same version of an app on two devices and both have one signature, each device will use up one of your 25 signatures. The only time multiple signatures are used is if you install a different version of an app on the same device (which we don’t recommend). In this case, that new version will be signed using a different signature from your original installation—so now two signatures are being used instead of one.
If you have multiple apps installed that use signature and you’re wondering why your signature count seems low, it’s because each app is counted separately. So if you have three apps installed that use signature, the total number of available signatures will be 25 (not 3×25).
The signature consumption of the application is based on the current version
The signature consumption of the application during each installation is based on the current version. The current version is not necessarily the latest, but it’s always the version that’s installed on your device and will be used for signature consumption.
If you want to see which version is installed on your device, go to “Settings > Apps & notifications” and tap the application’s name. Next, tap “Apps.”
The signature consumption rules between iOS and Android are different
The signature consumption rules between iOS and Android are different.
-iOS signatures are consumed when the application is installed, while Android signatures are consumed when the application is run. This means that if you install an app on your iPhone, its signature will last for a longer time than on your Android phone.
-The number of consumed Android signatures per installation is smaller than that of iOS device installations.
In other words, on Android phones, the signature is consumed when you run an application for the first time. This means that if you install an app on your iPhone, its signature will last for a longer time than on your Android phone. The number of consumed Android signatures per installation is smaller than that of iOS device installations.
There are several points to be noted
The following are some important things to note when using signatures (App签名)in-app installation operations:
Signatures are consumed for each installation. If you have an app that has multiple application versions installed on the same device, there will be a different signature consumption rule depending on whether you use push notification or mediation. For example, if you only have one version of the application and it is installed on multiple devices at once, then each device consumes its signature. But if your app has multiple versions and they’re all installed at once via push notification or mediation, then all of those applications share a common certificate validation profile (CVFP) for all of their apps. Therefore, even though there may be several different versions on those devices consuming their own sets of signatures from your mobile identity provider (MIP), they still share the same CVFP when installing applications from your MIP’s Catalog API calls.
In general
As mentioned before, the signature consumption of an app installation operation is based on the current version. In addition to this, there are some other things to note when using signatures in-app installation operations. For example, if you want to use a different signature for each application installed on your device, then you’ll have to make sure that they have different names and package IDs. If they don’t meet these requirements then they will share one signature across all apps which means they will consume just one signature instead of multiple ones when installing or updating applications on your device!
