5.扫二维码插件barcodescanner与camera插件冲突解决办法

找到该文件:..\plugins\phonegap-plugin-barcodescanner\plugin.xml

移除<uses-feature android:name="android.hardware.camera">

重新添加 platform

6.签名包无法访问 https 接口

参考文档:http://ivancevich.me/articles/ignoring-invalid-ssl-certificates-on-cordova-android-ios/

android:

project/platforms/android/CordovaLib/src/org/apache/cordova/engine/SystemWebViewClient.java

修改onReceivedSslError方法，修改如下

public void onReceivedSslError(WebView view, SslErrorHandler handler, SslError error) {

handler.proceed();

}

ios:

project/platforms/ios/Project/Classes/AppDelegate.m

将AppDelegate.m文件下修改为：

@implementation NSURLRequest(DataController)

+ (BOOL)allowsAnyHTTPSCertificateForHost:(NSString *)host

{

return YES;

}

@end

7.Ionic WKWebView 出现跨域请求的问题

强制cordova使用UIWebView引擎渲染页面

(1)在config.xml里增加以下配置

(2)卸载WKWebView插件

$ ionic cordova plugin remove cordova cordova-plugin-ionic-webview --save

8.微信不兼容cordova7.0.0

这是cordova版本太高，不兼容这个插件所导致的。解决方案是修改$your_project/plugins/cordova-plugin-wechat/scripts/android-install.js中的

var targetDir = path.join(projectRoot, "platforms", "android", "src", packageName.replace(/\./g, path.sep), "wxapi");

修改为

var targetDir = path.join(projectRoot, "platforms", "android", "app","src","main","java", packageName.replace(/\./g, path.sep), "wxapi");

修改后，重新装一下平台

cordova platform remove android

cordova platform add android
