Wireless CarPlay connection initialization (Wi-Fi Direct and hotspot modes)

Technical Positioning
Broad compatibility across Android head unit versions and BYD models
SaaS Insight & Market Implications
This issue exposes a critical regression in DiPlay versions 0.2.6 and 0.2.7, specifically impacting wireless CarPlay initialization on BYD head units running Android 10 (DiLink 4.0). The core problem is an `Android framework API compatibility issue`, manifesting as a `NoSuchMethodError` when `WifiP2pConfig.getNetworkName()` is called during Wi-Fi P2P preflight. This indicates DiPlay is attempting to use an API method unavailable on certain Android versions or OEM customizations, leading to connection loops or complete failure. The problem is widespread across various BYD models and controller configurations, suggesting a systemic incompatibility with the BYD Android ecosystem. The inability to connect wirelessly renders the product unusable for a significant segment of its target market. This necessitates a robust compatibility strategy, potentially requiring version-specific builds or dynamic API checks to address fragmentation in Android head unit environments.

Raw Developer Origin & Technical Request

Source Icon GitHub Issue Sep 29, 2026
Repo: shihabal3amri/DiPlay
[Bug] a loop error occurred After upgrading to 0.2.6

### DiPlay version

0.2.6

### Car and head-unit model

BYD-qin,DiLink 4.0,android 10

### iPhone model and exact iOS version

18.7.1

### Connection

Wireless

### What happened and how to reproduce it

After upgrading from version 0.2.0 to 0.2.6, the following error occurred:
1. When using wifi direct mode, the connection screen flashes and then exits to the initial screen (like bug: github.com/shihabal3amri/DiP... ).
2. When using WiFi hotspot mode, the screen stays at Getting Carplay ready and cannot enter the Carplay screen.
I tried reinstalling version 0.2.6, but the issue still persists.

Then I tried to delete and install version 0.2.0, connected in wifi direct mode, and entered the carplay screen normally (wifi hotspot mode was not tested here).

### Diagnostic report or recording

The attachment DiPlay-20260929-182336-749. txt is a diagnostic report using wifi direct mode in version 0.2.6,
The attachment DiPlay-20260929-203749-965.txt is a diagnostic report using wifi hotspot mode in version 0.2.6

### Bug: Wireless CarPlay Wi-Fi P2P Initialization Failure I have encountered the **same Wi-Fi P2P compatibility issue** on a BYD Song Plus vehicle with the 17 Controller configuration. The issue occurs during the wireless CarPlay connection process. The application fails when initializing the Wi-Fi P2P connection and reports the following error: No virtual method getNetworkName()Ljava/lang/String; in class Landroid/net/wifi/p2p/WifiP2pConfig; or its super classes The failure occurs during: ```text STEP wifi/ap: starting the wireless CarPlay access point ↓ wireless bring-up ↓ Wi-Fi P2P preflight ↓ WifiP2pConfig.getNetworkName() ↓ NoSuchMethodError ↓ wireless bring-up failed This appears to be the **same Android framework API compatibility issue** seen on other BYD head units. The vehicle information is: - Vehicle: BYD Song Plus - Controller: 17 Controller - Connection:** Wireless CarPlay - Issue:** Wi-Fi P2P initialization failure - Error:** `WifiP2pConfig.getNetworkName()` m...

0.2.7 also has this problem: Wi-Fi Direct connection keeps looping/reconnecting wirelessly and cannot enter the interface.

Using an iPhone 13 Pro running OS 17.7.2, the same issue was also encountered on a Dlink 4.0 (9.0), a vivo 2405A (15), and a Redmi K50 (12). By the way, I was using the car head unit's hotspot.
