android - 在 Android Studio 中为 android 构建 Chromium 时出错

问题描述

我正在尝试在 Ubuntu 16.04 机器上为 Android 构建 Chromium 作为 Android Studio 项目。

我按照here和here的说明成功创建了一个gradle项目。但是在Android Studio（3.1.2 stable）中导入后出现很多构建错误。

生成 gradle 项目的命令 -

build/android/gradle/generate_gradle.py --output-directory out/Default --project-dir ~/Projects/chromium_source/gradle_project

Android Studio 中的错误 -

构建项目

FAILURE: Build failed with an exception.

What went wrong:

build/android/gradle/generate_gradle.py --output-directory out/Default --target //chrome/android:chrome_public_apk

更新：

将--full标志添加到命令会添加包含所有缺失依赖项的提取的 srcjars和提取的资源文件夹。但是，这会完全挂起我的机器，除非我有选择地构建目标。

build/android/gradle/generate_gradle.py --output-directory out/Default --full --target //chrome/android:chrome_public_apk --target //chrome/android:chrome_junit_tests

我不得不在chrome_public_apk build.gradle 中进行一些额外的更改以修复更多错误 -

cannot find symbol class GeneratedMessageLite

从java.filter.exclude 中删除这一行 "com/google/protobuf/*.java"
duplicate class: com.google.protobuf.LazyFieldLite

在java.srcDirs中替换

"../../../../src/third_party/android_protobuf/src/java/src/main/java"

经过

"../../../../src/third_party/android_protobuf/src/java/src/main/java/com/google/protobuf/nano"
cannot access ViewerType class file for com.google.vr.ndk.base.GvrApi$ViewerType not found

在依赖项块中替换

"../../../../src/out/Default/lib.java/third_party/gvr-android-sdk/gvr_common_java.jar"

经过

"../../../../src/out/Default/lib.java/third_party/gvr-android-sdk/gvr_common_java.interface.jar"

编译器错误消失了，但失败并出现以下错误 -

我也尝试过使用 D8 dexer；没有帮助。
