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，我得到一个白色的屏幕，上面写着“MyApp，不幸的是，已经停止了”。我如何以及在何处添加Chromium WebView？

下面的日志显示它缺少Chromium WebView，但我似乎无法弄清楚那是什么或者添加到那里。

我找到http://docs.phonegap.com/en/3.0.0/guide_platforms_android_webview.md.html但是cordovaWebView和Chromium一样吗？该文件似乎也已过时。

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 "

Answer 1

＆＃34;是与Chromium相同的cordovaWebView＆＃34; - 是的，它应该是。该文档的最新版本为here。

您最好的选择是使用Cordova CLI或Sencha Cmd构建Sencha Touch应用程序，因为所有WebView设置都是自动完成的。

我不完全确定如何修复您现有的设置，但我绝对鼓励您使用上述两种CLI工具中的一种......它可以减少出现此类错误的可能性。
