Welcome to Kiwi Browser
Kiwi Browser is a fully open-source web browser for Android.
Kiwi is based on Chromium, the engine that powers the most popular browser in the world so you won't loose your habits.
Among other functionalities, Kiwi Browser supports:
- Night Mode (another implementation than Chromium)
- Support for Chrome Extensions
- Bottom address bar It also includes performance improvements (partial rasterisation of tiles, etc)
The browser is licensed under the same licence as Chromium, which means that you are allowed to create derivatives of the browser.
Timeline
15 April 2018 - First Kiwi Browser release.
15 April 2019 - Kiwi Browser gets support for Chrome Extensions.
17 April 2020 - Kiwi Browser goes fully open-source.
This code is up-to-date and is matching the build on the Play Store.
The new builds are done from the open-source edition directly to the Play Store.
There are thousands of hours of work in this repository and thousands of files changed.
Contributors
Contributions are welcome and encouraged.
If you want your code to be integrated into Kiwi, open a merge request, I (and/or a member of the community) can review the code with you and push it to the Play Store.
Modifications
If you create your own browser or a mod, make sure to change the browser name and icon in chrome/android/java/res_chromium/values/channel_constants.xml and translation strings (search and replace Kiwi in all *.xtb, all *.grd and all *.grdp files)
How to build
The reference build machine is using Ubuntu 19.04 (tested also using Ubuntu 19.10).
Minimum system requirements is 2 vCPUs, 7.5 GB Memory.
You can use a virtual machine, or a Google Cloud VM.
Getting the source-code and environment
To build Kiwi Browser you can directly clone the repository, as we have packed all dependencies already:
-
In ~ (your home directory) run:
git clone https://chromium.googlesource.com/chromium/tools/depot_tools.git
and edit the file ~/.bashrc to add at the very end
export PATH=$HOME/depot_tools:$PATH
Run:
source ~/.bashrc
This will give you access to one utility called gclient (as in "Google client")
- Create a directory called ~/chromium/
In the chromium directory run:
git clone https://github.com/kiwibrowser/dependencies.git .cipd cp ~/chromium/.cipd/.gclient ~/chromium/ cp ~/chromium/.cipd/.gclient_entries ~/chromium/
-
Enter ~/chromium/ and run:
git clone https://github.com/kiwibrowser/src.git
At this stage, in ~/chromium/ you will have the .cipd folder, and a folder with the Kiwi Browser source-code called src.
Setting-up dependencies
-
Run:
sudo apt-get install python
-
In ~/chromium/src/ run install-build-deps.sh using:
bash install-build-deps.sh --no-chromeos-fonts build/linux/sysroot_scripts/install-sysroot.py --arch=i386 build/linux/sysroot_scripts/install-sysroot.py --arch=amd64
This script will install all necessary system packages using apt-get and gather a minimal build filesystem.
Configuring the build type and platform
- In ~/chromium/src/, create a folder named "android_arm" and in this folder create a file called args.gn with this content:
args.gn:
target_os = "android" target_cpu = "arm" # <---- can be arm, arm64, x86 or x64 is_debug = false is_java_debug = false android_channel = "stable" is_official_build = true is_component_build = false is_chrome_branded = false is_clang = true symbol_level = 1 use_unofficial_version_number = false android_default_version_code = "158" android_keystore_name = "production" android_keystore_password = "HERE_YOUR_ANDROID_KEYSTORE_PASSWORD" android_keystore_path = "keystore.jks" android_default_version_name = "Quadea" fieldtrial_testing_like_official_build = true icu_use_data_file = false enable_iterator_debugging = false google_api_key = "KIWIBROWSER" google_default_client_id = "42.apps.kiwibrowser.com" google_default_client_secret = "KIWIBROWSER_NOT_SO_SECRET" use_official_google_api_keys = true ffmpeg_branding = "Chrome" proprietary_codecs = true enable_hevc_demuxing = true enable_nacl = false enable_wifi_display = false enable_widevine = false enable_google_now = true enable_ac3_eac3_audio_demuxing = true enable_iterator_debugging = false enable_mse_mpeg2ts_stream_parser = true enable_remoting = false rtc_use_h264 = false rtc_use_lto = false use_openh264 = false v8_use_external_startup_data = true update_android_aar_prebuilts = true use_thin_lto = true enable_extensions = true enable_plugins = true
Replace Android keystore password and Android keystore keypath with the data for your Android keystore (or you can generate a new key)
To prepare initial setup run:
gclient runhooks
then generate the build files:
~/chromium/src$ gn gen out/android_arm # (you can also use 'gn args out/android_arm') Writing build/secondary/third_party/android_tools/google_play_services_basement_java.info Writing build/secondary/third_party/android_tools/google_play_services_tasks_java.info Writing third_party/android_support_test_runner/rules_java.info Writing build/secondary/third_party/android_tools/google_play_services_base_java.info Writing build/secondary/third_party/android_tools/google_play_services_auth_base_java.info [...] Done. Made 19910 targets from 1626 files in 21974ms
===
To compile, use the command: ninja -C out/android_arm chrome_public_apk
you'll have the output APK in ./out/android_arm/apks/ChromePublic.apk
then you can run the APK on your phone.
To investigate crashes
components/crash/content/tools/generate_breakpad_symbols.py --build-dir=out/lnx64 --symbols-dir=/tmp/my_symbols/ --binary=out/android_arm/lib.unstripped/libchrome.so --clear --verbose
or from a tombstone:
~/chromium/src$ ./third_party/android_ndk/ndk-stack -sym out/android_x86/lib.unstripped -dump /home/raven/tombstone_06
==
Remote debugging
You can use Google Chrome to debug using the devtools console.
In case the devtools console doesn't work (error 404), the solution is to use chrome://inspect (Inspect fallback) or change SHA1 in build/util/LASTCHANGE
LASTCHANGE=8920e690dd011895672947112477d10d5c8afb09-refs/branch-heads/3497@{#948}
and confirm the change using:
rm out/android_arm/gen/components/version_info/version_info_values.h out/android_x86/gen/components/version_info/version_info_values.h out/android_arm/gen/build/util/webkit_version.h out/android_x86/gen/build/util/webkit_version.h out/android_arm/gen/chrome/common/chrome_version.h out/android_x86/gen/chrome/common/chrome_version.h
Binary size optimization
If you want to optimize of the final APK, you can look at the size of each individual component using command:
./tools/binary_size/supersize archive chrome.size --apk-file out/android_arm/apks/ChromePublic.apk -v ./tools/binary_size/supersize html_report chrome.size --report-dir size-report -v
