Continue reading to see How to Enable Camera2 API on Android, as here it is all covered.
The Camera2 API is basically used by the developers to interact with the Android device's camera hardware. Every third-party camera app uses this API, including GCam. So, basically, Camera2 unleashes a number of powerful features via the API, which is why most manufacturers have it disabled by default.
Why Do You Need Camera2 API?
Simplistically, the Camera2 API provides your applications with the tools they need to interact with and change settings on their phone's camera. While the nitty-gritty of how it works goes beyond the scope of this tutorial, you should know it underpins the majority of third-party camera apps. The reason for this is that, other than all the rest of the services, the Camera application needs direct interaction with the hardware in order to serve its purpose. Take, for example, the default WhatsApp camera. The WhatsApp camera allows the user to take photos and videos, switch between front and back cameras, and turn the flash on or off. Then there are dedicated, fully functional camera apps like GCam that provide all the basic features of taking RAW photos, adjusting white balance, shutter speed, ISO, manual focus, etc. Camera2 API is meant for these later ones.
See if the Camera2 API is enabled on your device.
First, ensure that the Camera2 API is enabled on your phone. You can either use an application from the marketplace which does the checking for you, or do some research yourself by looking at compatibility threads online. To do the latter, open the Google Play Store and download the "Camera2 API Probe" app.
This app will help you to find out whether your phone is Camera2 compatible. So, under the heading "Hardware Support Level," you will see a few different definitions. Let me explain:
CAUTIONS: Camera ports may not work correctly, and with big problems and bugs in the future.
LEGACY: Only a minimal subset of camera features will be available, and higher-level controls will be very limited.
FULL or LEVEL 3 means your phone fully supports third-party camera ports, and Camera2 API is enabled.
Camera2 API Probe will be able to inform you about everything, including supported features and their boundaries. It will differentiate the front and back cameras and will also provide you with all the information on the supported frame rate, focus mode, exposure, stabilization, and preview size for your video.
How to Enable Camera2 API on Your Android Phone?
A number of methods to turn the Camera2 API on in your device are described below. Please note that each of these steps strictly requires system file modification. If it's just a different camera application you're after, well, there's GCam Go. It includes all the basic functionality you might need, and it does not require your phone to have Camera2 enabled for it to work fully.
1) Camera2API Magisk root module
Despite the fact that it entails rooting, due to the modular nature of Magisk, this method is quite easy to flash the fix into your phone, thus bypassing the Camera2 limitations.
Go to the GitHub page of jhangyu and download the Camera2API module.
Enable the module
Launch Magisk head to Modules, bottom right corner. Click "Install from Storage" and choose the.zip you've just downloaded.
Power your device off.
2) Terminal Emulator Based Root
Using KernelSU or any other rooting tool, you can enable API and edit the build.prop files with the support of an application called the Terminal Emulator.
Download the Terminal Emulator application on your mobile first.
enabled 1 setprop persist.camera.HAL3.
enable vendor.persist.camera.HAL3 1
Press the Enter button and reboot your device.
The following lines need to be written in /system/build to enable API.
3) Non-Rooted, Unlocked Bootloader (TWRP)
The addition of those two commands above in the build.prop file for those not having root access can also be done via TWRP. Since you might easily brick your device by playing with the wrong files, first you should back up all of your data and proceed with caution.
First, you install ADB on your PC.
If this is your first time setting up ADB, we highly recommend going through our in-depth tutorial.
Just download the TWRP recovery file and save it to a new file named twrp.img.
Connect your phone to your computer using the USB cable.
Open the following commands in Command Prompt of the Platform Tools to boot into TWRP.
devic rites from adb
Bootloader reboot using adb
quickboot start twrp.img
After your device boots into TWRP, find the "Swipe to Allow Modifications" bar and swipe it.
To enable Camera2 API via ADB Shell, activate your Command Prompt and execute the following commands.
equipment from adb
randb shell
enabled 1 setprop persist.camera.HAL3.
exit
to force a reboot
Having done either of the two above, and after checking the status of the Camera2 API, you shouldn't have any problem whatsoever in using Google Camera or any port. Note, however, that when you reset your device, you might need to do this all over again.
