Chromium Android build crash with libcrashpad_handler_trampoline.so

[Nishchal Visavadiya]

We are building chromium for Android.
We have successfully added built the APK using commands provided [here](https://chromium.googlesource.com/chromium/src/+/main/docs/android_build_instructions.md).

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](https://chromium.googlesource.com/chromium/src/+/main/docs/android_studio.md) 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.

Release builds also include libcrashpad_handler_trampoline.so and you need to include this in your APK. It sounds like you are doing some custom build process, so we may not be able to help figure out why it's not included.

Can you please at least guide on how to get the libcrashpad_handler_trampoline.so in release builds?

We have generated multiple release build with different flags but it does not generate this SO in the build folder.
