quasar + cordova项目更换icon

我之前写了如何使用 quasar项目+cordova打包成apk，这种情况下运行到手机的apk可以使用，但apk安装的图标是cordova的 logo 

quasar文档中有更换cordova应用图标的教程：Cordova 应用的图标 | Quasar 中文文档 | Quasar 框架中文网 (quasar-cn.cn)

cordova更换icon教程：Customize App Icons - Apache Cordova

不过我安装Icon Genie CLI时报错了，想了想我还是选择了直接更换cordova项目中的图标。

【建议】把更换图标放到最后一步！！也就是所有功能都改完了、也调试好了，只剩下图标的时候再更换！

因为要修改src-cordova中的文件，如果重新修改了代码，使用 quasar build -m android 的时候要重新生成src-cordova中的内容，会报错 ：

> Task :app:mergeReleaseResources FAILED

FAILURE: Build failed with an exception.

* What went wrong:

   > Android resource compilation failed

  cordova platform add android  之后文件目录如下：

  

 此时运行到手机  quasar dev -m android 

 按照Cordova 应用的图标 | Quasar 中文文档 | Quasar 框架中文网 (quasar-cn.cn)中文件目录所示：

在 /src-cordova 下新建 res 文件夹，和 config.xml 同级，res中再新建 android ，android中放图片

在 config.xml 中 <widget>内部指定平台和icon图片

<platform name="android">
    <icon density="ldpi" src="res/android/favicon-128x128.png" />
</platform>

 

然后先 quasar build -m android 一下，然后进入 src-cordova 运行到手机：cordova run android ，应用图标就换了

 再换一张图片看看：

<platform name="android">
    <icon density="ldpi" src="res/android/momo.png" />
</platform>

如果修改了代码，需要重启  quasar build -m android  ,但此时src-cordova中的res不是quasar自动生成的，所以quasar build会报错：

> Task :app:mergeReleaseResources FAILED

FAILURE: Build failed with an exception.

* What went wrong:

 此时可以删除src-cordova文件，重新   quasar dev -m android  

 所以建议所有的功能都改完了以后，最后一步再换图标！

如果提示，是因为run之前没有 quasar build -m android.
