Installation guide

1
Download the APK

Tap the download button above and save the APK to your phone or computer. If you are downloading on a phone, saving to the Downloads folder is easiest.

2
Move the file to the car display

Copy the APK to the car display by USB drive, a phone connected over USB, or any built-in file transfer option your system provides.

3
Allow unknown app installs

In the car system settings, look under Security for an option such as "Install unknown apps" or "Allow unknown sources." The exact path varies by system.

4
Open the APK to install

Find the APK in the file manager, open it, and follow the prompts. Installation usually takes about 30 seconds.

5
Set it as the default launcher

After installation, the system may ask which launcher to use. Choose SmartCar Launcher and tap "Always." If you are not prompted, go to:Settings -> Apps -> Default apps -> Home app and switch it manually.

1
Prepare a USB drive (recommended)

Copy the APK to the root of a USB drive formatted as FAT32 or exFAT. Most car displays recognize one of these formats.

2
Plug the drive into the car display

Insert the USB drive into the vehicle USB port. Many systems will open a file manager or show a USB prompt automatically.

3
Open the file manager

Look for an app such as "Files" or "My Files," then open the USB drive and find the APK. If your system has no file manager, you cancontact supportfor a recommended file manager APK.

4
Install the APK

Open the APK and complete installation by following the prompts. On the first install you may need to confirm install permission.

5
Set as default launcher, then restart

When the launcher picker appears, choose "SmartCar Launcher -> Always." Restarting the system afterward helps ensure the setting sticks.

No USB drive available? You can also try this path:
Connect your phone by USB -> choose file transfer mode -> browse phone storage from the car system file manager -> install the APK.
Installer says "signature mismatch" or "a newer version is already installed"?
Remove the older SmartCar Launcher build first and try again. If the signature mismatch remains, your current and previous packages were signed differently, so switch to another channel such as Public -> AOSP.
Installed successfully, but crashes on launch?
Try this: 1) confirm required permissions such as storage or overlay access, 2) restart the car system and launch again, 3) reinstall another channel build, 4) if it still fails after several attempts, pleasecontact supportshare your car display model.
How do I make SmartCar Launcher the default home screen?

Option 2:Go to Settings -> App management -> Default apps -> Desktop/Homeand choose SmartCar Launcher.
Option 3:Inside SmartCar Launcher settings, use the built-in "Set as default launcher" shortcut.
