我正在尝试让 Buck 使用 Android Studio 中的 balnk 应用程序模板。

apps/snappy/BUCK

android_binary(
  name = 'main',
  manifest = 'AndroidManifest.xml',
  keystore = '//keystores:debug',
  package_type = 'debug',
  deps = [
    '//java:main',
    '//res:res',
    '//keystores:debug',
  ],
)

res/snappy/layout/activity_main.xml

<?xml version="1.0" encoding="utf-8"?>
<android.support.design.widget.CoordinatorLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:fitsSystemWindows="true"
    tools:context="com.whitedrop.snappy.MainActivity">

    ....

</android.support.design.widget.CoordinatorLayout>

res/BUCK

android_resource(
  name = 'res',
  res = 'snappy',
  package = 'com.whitedrop.snappy',
  deps = [
  '//libs:appcompat-v7',
  '//libs:design'
  ],
  visibility = [
    'PUBLIC',
  ]
)

libs/BUCK

android_prebuilt_aar(
  name = 'appcompat-v7',
  aar = 'appcompat-v7-23.0.1.aar',
  visibility = ['PUBLIC']
)
android_prebuilt_aar(
  name = 'design',
  aar = 'design-23.0.1.aar',
  visibility = ['PUBLIC']
)

输出

编辑:我的 apk 在其 dex 文件 btw 中包含 CoordinatorLayout 类

EDIT2:完整的代码可以在这里找到https://github.com/vinz243/snappy

EDIT3:尝试从 AppCompatActivity 扩展:

这是 MainActivity.java:

package com.whitedrop.snappy;

import android.os.Bundle;
import android.app.Activity;
import android.view.Menu;
import android.support.design.widget.FloatingActionButton;
import android.support.design.widget.Snackbar;
import android.support.v7.app.AppCompatActivity;
import android.support.v7.widget.Toolbar;

public class MainActivity extends AppCompatActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
    }

    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        // Inflate the menu; this adds items to the action bar if it is present.
        getMenuInflater().inflate(R.menu.activity_main, menu);
        return true;
    }

}

通过向 deps 添加支持 v4 来修复上述错误。现在我在运行时得到:

确保您在BUCK配置中提到的版本是正确的。

在您在问题中共享的代码中,我看到v23.0.1了支持和设计库。在您的 github 存储库中,我看到了v23.4.0.

在此处输入图像描述

我怀疑是这个原因。更改为您包含在 libs 文件夹中的正确版本,看看它是否有效。

更新以响应您问题中的编辑 5:

以下两个依赖项将有助于解决VectorDrawableCompat ClassNotFoundException. 以适合 BUCK 的方式包含它们。

compile 'com.android.support:support-vector-drawable:23.4.0'
compile 'com.android.support:animated-vector-drawable:23.4.0'

尝试扩展MainActivityAppCompatActivity而不是Activity

然后进行全新安装。

androidx与 BUCK 无关,但对我来说,我在使用混合android.support.v7库时遇到了这个错误。在此处查看我针对该错误版本的解决方案:https ://stackoverflow.com/a/52490825/1762493
