Class

• Platform differences: When calling this function under the Android platform, in addition to the appID, the Application class object must also be passed in.

• When to call: Before calling other member functions, you must call this API to create a ZIM example.

Usage restrictions: Currently only one instance is supported, repeated calls will return [null].

Precautions:

1. Currently, the [create] function can only create one instance at most. If it is called multiple times, only the first one will return a valid instance, and the rest will be [null]. The developer should save the ZIM instance by himself, and ensure that the life cycle of the instance is available in the process of using the ZIM business function; or after calling [create], he can use [getInstance] to obtain its singleton object and call other member functions.

2. If you use this function to create an instance, you must pass in both AppID and AppSign (exclude Web platform).

Scope of Impact: Failure to call this function will prevent other member functions from being called.

Platform difference: When calling this function on the Android platform, in addition to the appID, the Application class object must also be passed in.

• Use cases: 1. When the SDK is running, the developer finds that it does not match the expected situation and submits the problem and related logs to the ZEGO technical staff for locating. The ZEGO technical staff may need the information of the engine version to assist in locating the problem.

2. Developers can also collect this information as the version information of the engine used by the app, so that the SDK corresponding to each version of the app on the line.

When to call : It can be called at any time.

• When to call: You must call [create] to create an instance before calling this function to obtain a singleton object, otherwise it will return [null].

Related interface: [create].

• When to call: It must be called before [create].

If the developer calls after [create], the SDK will save this configuration until the next time [create] takes effect.

Life cycle: Set before calling [create], and take effect when calling [create]. If the developer does not set a new log configuration in the next [create], the previous configuration will still take effect.

Platform difference: The default path of different platforms is different, please refer to the default value.

Call timing: It must be called before [create].

If the developer calls after [create], the SDK saves the configuration until it takes effect the next time [Create] is invoked.
