Android 应用程序无法开始缺少 Chromium WebView

Question

我正在使用带有 phonegap/cordova 的 sencha touch 来构建 android 应用程序。当我的应用程序启动时，我得到一个白屏，上面写着“不幸的是，MyApp 已停止”。如何以及在何处添加 Chromium WebView？

下面的日志说它缺少 Chromium WebView，但我似乎无法弄清楚它在哪里或要添加什么。

我找到了http://docs.phonegap.com/en/3.0.0/guide_platforms_android_webview.md.html，但是 cordovaWebView 和 Chromium 一样吗？此外，该文档似乎已过时。

我为构建运行的小脚本

import os
# run a build for this app
os.system("sencha -d app build -run native");
# change directory into phonegap directory
os.chdir( os.getcwd() + "\phonegap" );
# push the app to the device
os.system("phonegap run android");
print " Script Complete "

“cordovaWebView 是否与 Chromium 相同”- 是的，应该如此。该文档的最新版本是here。

最好的办法是使用 Cordova CLI 或 Sencha Cmd 构建 Sencha Touch 应用程序，因为所有 WebView 设置都是自动为您完成的。

我不完全确定如何修复您现有的设置，但我肯定会鼓励您使用上述两种 CLI 工具之一...它可以减少出现此类错误的可能性。
