2. Solutions

In order to solve this problem, we need to start from the following aspects and implement corresponding solutions for each situation:

The first case:

There are specific instructions in 2 and 3 in the document, we will check according to our actual situation.

The second case:

Since this application is tested by overseas applications in China, we also have to consider whether the scene meets the relevant conditions that overseas applications need to meet when they are tested in China.The specific conditions are as follows:

For overseas applications to be tested in China, the following conditions must be met:
1. The test machine should be an overseas device, and the network environment should be the network in the corresponding overseas region.In the case of using WIFI, it is recommended not to insert the SIM card, otherwise you should make sure that the SIM card is the SIM card of the corresponding region;
2. Change the country and device language in the mobile phone application market to the corresponding region as much as possible;
3.The location of the mobile phone region should be changed to the corresponding region, and the change method:
Settings -> System and Updates -> Language and Input Method -> Language and Region -> Region
Settings -> System & updates -> Language & input -> Language and region -> Region
4. The system time of the mobile phone is set to the standard time.
Description:
Overseas devices, overseas networks, and mobile phone regions must be guaranteed to be overseas. Some advertisements will match the device language, so it is best to change the language of the corresponding region. The SIM card and application market country areInterference factors, the SIM card will affect which server address to send the request to.
