1、安装插件,也可以用ionic plugin add ....
phonegap local plugin add https://git-wip-us.apache.org/repos/asf/cordova-plugin-camera.git
phonegap local plugin add https://git-wip-us.apache.org/repos/asf/cordova-plugin-media-capture.git
phonegap local plugin add https://git-wip-us.apache.org/repos/asf/cordova-plugin-media.git
2、打开android项目,添加权限配置
--> app/res/xml/plugins.xml
<plugin name="Camera" value="org.apache.cordova.CameraLauncher" />
--> app/AndroidManifest
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.CAMERA" />
<uses-feature android:name="android.hardware.camera" />
<uses-feature android:name="android.hardware.camera.autofocus" />
