Cordova-掃描二維碼(豎屏)

首先想到的是安裝cordova plugin add cordova-plugin-barcodescanner插件javascript

插件安裝的比較順利,可是打包時總出現問題,按下面解決方法ok
This is how I've solved it.
1. Open plugins/cordova-plugin-barcode-scanner/plugin.xml and delete all records xmlns:android=""
2. Open  platforms/android/android.json and delete all xmlns:android=\"\"
3. Do the same in platforms/android/AndroidManifest.xmlhtml

打包完成後,裝到手機上,打開app ,彈出alert scanning failed:write settings:false ,不能掃描。前端

最後在platforms\android\AndroidManifest.xml 文件中修改配置文件目標sdk爲22,掃描okjava

<uses-sdk android:minSdkVersion="16" android:targetSdkVersion="22" />android

可是發現掃描不能豎屏使用,橫屏很不方便。json

後來發現phonegap-plugin-barcodescanner插件能夠豎屏掃描,因而趕忙安裝這個插件試試app

安裝步驟gradle

(1)首先按正常流程初始化項目,默認安裝的是cordova-build 是6.1.2版本,安裝它須要6.3及以上版本ui

         更新cordova-build版本 cordova platform update android@6.3.0插件

(2)cordova plugin add phonegap-plugin-barcodescanner

        在安裝的時候會下載gradle-3.3-all.zip,估計網速慢的緣由下載不下來,須要手動下載

       而後放到E:\cordova\hello\platforms\android\gradle目錄裏
       同時修改E:\cordova\hello\platforms\android\cordova\lib\builders 下的GradleBuilder.js
      var distributionUrl =process.env['CORDOVA_ANDROID_GRADLE_DISTRIBUTION_URL'] || '../gradle-3.3-all.zip';

(3)<uses-sdk android:minSdkVersion="16" android:targetSdkVersion="26" />   targetSdkVersion        改爲26
       Android SDK Manager內同時下載SDK Platform  Android 8.0.0(API26)

順利安裝完成!!!
