Chromium android runtime issue

Question

We are building chromium for Android. We have successfully added built the APK using commands provided here

We have created the build using below GN args.

target_os = "android"
target_cpu = "arm64"
android_channel = "stable"
is_debug = false
is_official_build = true
is_component_build = false
is_clang = true
symbol_level = 0
blink_symbol_level=0
use_unofficial_version_number = false
v8_use_external_startup_data = true
icu_use_data_file = false
ffmpeg_branding = "Chrome"
proprietary_codecs = true
exclude_unwind_tables = true
chrome_pgo_phase = 0

After that we have followed this android studio specific guide and generate a android wrapper project. Using this wrapper we are extracting the Java, XMLs, SO and other resources to build directly in android studio. We have done this successfully and the App is working fine but issue occures when we search.

The app crashes on any URL search (even chrome URLs such as: chrome://version) with below error by libchrome.so file.

error: unable to open file "/data/app/~~VZ6JSoritWLt73RxWsu5yg==/org.chromium.chrome-fCO_LyriifFjdrNCMbQC_A==/base.apk!/lib/arm64-v8a/libcrashpad_handler_trampoline.so"

And few lines below that:

After trying to find the libcrashpad_handler_trampoline.so we manage to find it in a build folder with GN flag is_debug = true. But we want to build with is_debug = false and doing so the app crashed on search with above logs.

Please let us know if anyone have understanding on Chromium android, thanks.

Why not debug it? Release versions can be debugged too. To debug it, remove symbol_level = 0 from your GN file. It will make debugging almost impossible — Asesh

removing symbol_level = 0 would mean it would take default value of -1. Which is auto set based on build type. — nil

we have tried with symbol_level = 1 and it does produce the same errors. — nil

symbol_level specifies the level of debug symbol to embed into your app. By default it should be either 1 or 2. I think it's 2. It has nothing to do with this error message. — Asesh

@Asesh Did try with symbol_level = 2, but logs do not describe more info. Are you referring to debugging the SO file? if yes then could you provide any helpful documents on that? It would be a gear help. Appreciate you help so far, thanks. — nil

building with is_debug=true allows you to check the log statements. which might lead to the exact issue. where as i would suggest if you have not made any changes to the codebase yourself, restart the build process. because sometimes the project gets corrupted. i myself faced some issues in the earlier builds.

Thanks for helping out @yogesh swami. i have already build it successfully few days ago. Still not sure what was the issue but building again solved the issue.
