Other Variables

ASWV_ORIENTATION = 0;   // change device orientation to portrait (1)(default) or landscape (2) or unspecified (0)
ASWV_LAYOUT      = 0;   // default=0; for clear fullscreen layout and 1 to add drawer and navigation bar

ASWV_SEARCH      = "https://www.google.com/search?q=";   // search query will start by the end of the present string
ASWV_SHARE_URL   = ASWV_URL+"?share=";   // URL where you process external content shared with the app
ASWV_EXC_LIST    = "github.com";       // domains allowed to be opened inside webview; separate domains with a comma (,)

ASWV_ADMOB       = "ca-app-pub-9276682923792397~7957851075";   // your unique publishers ID; this one is temporary

ASWV_F_TYPE      = "*/*"   // use `image/*` for image files only; check file type references for custom file type

POSTFIX_USER_AGENT      = true;     // set to true to append USER_AGENT_POSTFIX to user agent

Features

GPS Location

ASWP_LOCATION needs to be set true if your app needs GPS location coordinates, in this case app will start requesting GPS location data of the device on regular intervals (specifically when some fragment is changed or requested by the user). All of the recorded data will be sent to the active webpage in form of cookies, to store it in logs locally, try PQL.

COOKIE "lat" for latitude
COOKIE "long" for longitude

Camera Input

You have the flexibility to choose between selecting input from both the file manager and the camera, or just choosing a single input medium. Additionally, you can also specify a particular file type or even single or multiple files. To get video input, you can add a file type condition in your HTML input using video/* for videos and image/* for photos. By default, the ASWV_F_TYPE is set to */*, and it is suggested not to change it. Instead, file types should be provided on the active web page's end.

Firebase Messaging

You need a firebase account to get started. Then download google-services.json from firebase panel, and put it in the app level directory. Then you can create a POST request from your server end, like the sample below. Check detailed steps to download firebase config file.

To URL: https://fcm.googleapis.com/fcm/send

Header:

content-type:application/json
authorization:key=__server_key_here__ (Firebase > Settings > Cloud Messaging)

Data:

{ "notification": {
    "title": "__title_string__",
    "text": "__text_string__",
     "click_action": "Open_URI"
  },
    "data": {
    "uri": "__the_URL_where_you_want_users_to_send__"
    },
  "to" : "__user_token__"
}

You can get __user_token__ from COOKIE fcm_token.

Google AdMob

Enable ASWP_ADMOB (permission variable) to show ads, and get your App ID from AdMob to replace ASWV_ADMOB (config variable).

Chrome Tab

With ASWP_TAB you can handle external link actions, whether to be opened in the chrome tab or external browser.

Content Sharing

Users can share external content with your application including text, link or image. You can received data on active web page end by proving ASWV_SHARE_URL endpoint that can handle such requests. To disable this feature, you need to remove ShareActivity from application Manifest.

User Interfaces

You can switch between clean and native interface with ASWV_LAYOUT where 0 represents full screen interface and 1 as drawer layout with search option and navigation bar.

To customize drawer bar, you can look into onNavigationItemSelected() method and activity_main_drawer.xml for menu items.

Rating System

Rating dialogue is enabled by default and can be handled by ASWP_RATINGS.

ASWR_DAYS            = 3;           // after how many days of usage would you like to show the dialog
ASWR_TIMES           = 10;          // overall request launch times being ignored
ASWR_INTERVAL        = 2;           // reminding users to rate after days interval
