javascript - How to have a widget on your app that can open without the need for passcode? -

-

i'm designing app in phonegap i'm using html, css, javascript etc.

this app uses phones camera (a qr scanner exact) , want users able use app quick possible. so, on android device can access camera without typing password, there way can same app ?

application still in design stages i'm getting first make sure want can developed before start development, thank you.

in java can define attribute widgetcategory in appwidget-provider home_screen|keyguard

    <appwidget-provider xmlns:android="http://schemas.android.com/apk/res/android"          android:minwidth="40dp"          android:minheight="40dp"          android:updateperiodmillis="86400000"          android:previewimage="@drawable/preview"          android:initiallayout="@layout/example_appwidget"          android:configure="com.example.android.exampleappwidgetconfigure"           android:resizemode="horizontal|vertical"          android:widgetcategory="home_screen|keyguard"> //like here </appwidget-provider>

but per google documents, feature has been taken down android 5.0 lollipop (only home_screen valid) work devices supporting android 4.2 or above below android 5.0 limited.

the widgetcategory attribute declares whether app widget can displayed on home screen (home_screen), lock screen (keyguard), or both. android versions lower 5.0 support lock-screen widgets. android 5.0 , higher, home_screen valid.
