Ulefone Armor X5 32Gb+3Gb Dual LTE [35/132] Api behavioral compatibility

Browser application (whether based on the upstream WebKit Browser application or a

third-party replacement).

However, If device implementations do not include a standalone Browser application, they:

[C-2-1] MUST still support the public intent patterns as described in section 3.2.3.1 .

3.5. API Behavioral Compatibility

Device implementations:

[C-0-9] MUST ensure that API behavioral compatibility is applied for all installed apps

unless they are restricted as described in Section 3.5.1 .

[C-0-10] MUST NOT implement the whitelisting approach that ensures API behavioral

compatibility only for apps that are selected by device implementers.

The behaviors of each of the API types (managed, soft, native, and web) must be consistent with the

preferred implementation of the upstream Android Open Source Project . Some specific areas of

compatibility are:

[C-0-1] Devices MUST NOT change the behavior or semantics of a standard intent.

[C-0-2] Devices MUST NOT alter the lifecycle or lifecycle semantics of a particular type of

system component (such as Service, Activity, ContentProvider, etc.).

[C-0-3] Devices MUST NOT change the semantics of a standard permission.

Devices MUST NOT alter the limitations enforced on background applications. More

specifically, for background apps:

[C-0-4] they MUST stop executing callbacks that are registered by the app to

receive outputs from the GnssMeasurement and GnssNavigationMessage .

[C-0-5] they MUST rate-limit the frequency of updates that are provided to the

app through the LocationManager API class or the WifiManager.startScan() method.

[C-0-6] if the app is targeting API level 25 or higher, they MUST NOT allow to

intents in the app's manifest, unless the broadcast intent requires a "signature"

or "signatureOrSystem" protectionLevel permission or are on the exemption list .

[C-0-7] if the app is targeting API level 25 or higher, they MUST stop the app's

background services, just as if the app had called the services' stopSelf()

method, unless the app is placed on a temporary whitelist to handle a task

that's visible to the user.

[C-0-8] if the app is targeting API level 25 or higher, they MUST release the

wakelocks the app holds.

[C-0-9] Devices MUST return the following security providers as the first seven array

values from the Security.getProviders() method, in the given order and with the given names

(as returned by Provider.getName() ) and classes, unless the app has modified the list via

insertProviderAt() or removeProvider() . Devices MAY return additional providers after the

specified list of providers below.

1. AndroidNSSP - android.security.net.config.NetworkSecurityConfigProvider

2. AndroidOpenSSL - com.android.org.conscrypt.OpenSSLProvider

3. CertPathProvider - sun.security.provider.CertPathProvider

4. AndroidKeyStoreBCWorkaround -

android.security.keystore.AndroidKeyStoreBCWorkaroundProvider

5. BC - com.android.org.bouncycastle.jce.provider.BouncyCastleProvider
