Loading html file from local folder into webview

Question

I\'m new to Android development.

I want to load a html file into a webview.

Note that there are so many relevant questions on SO like this,

Answer 1

In Android 4.4 KitKat, a "Not allowed to load local resource: file:///.." is thrown. arise when loadURL and the only alternative I've found is "loadDataWithBaseURL".

webView.loadDataWithBaseURL("file:///android_asset/demo/",
                             tmpDocumentText,"text/html", "UTF-8", null);

Answer 2

You can use:

   WebView webView = // ...

   webView.loadUrl("file:///myPath/myFile.html");

In an Android application, files can be read from 3 types of locations:

• Internal storage: Each app has its own, file names are relative to this location. URL takes form file:///myFolder/myFile.html

• External storage: Needs permission and may not always be available. Get the root folder by calling Environment.getExternalStorageDirectory(). So, construct the URL using: String url = "file:///" + Environment.getExternalStorageDirectory().toString() + File.separator + "myFolder/myFile.html"

• Assets: Stored in the apk. Read-only access. URL takes form file:///android_asset/myFolder/myFile.html (See also Loading an Android Resource into a WebView)

Answer 3

WebView has loadData method http://developer.android.com/reference/android/webkit/WebView.html

All you need to do is reading the file into String then feed it to WebView using loadData.
