Open local file in pdf.js android webview (“file” is not supported error)
0
I'm trying to follow the answer stated here. Based on the comments, loading a local file using pdf.js in android webview should work but I am getting the below error:
I/chromium: [INFO:CONSOLE(18556)] "Fetch API cannot load file:///android_asset/www/pdfjs/web/tracemonkey.pdf. URL scheme "file" is not supported.", source: file:///android_asset/www/pdfjs/build/pdf.js (18556)
I/chromium: [INFO:CONSOLE(13127)] "Uncaught (in promise) DataCloneError: Failed to execute 'postMessage' on 'Worker': TypeError: Failed to fetch could not be cloned.", source: file:///android_asset/www/pdfjs/build/pdf.js (13127)
[INFO:CONSOLE(985)] "Uncaught (in promise) Error: An error occurred while loading the PDF.", source: file:///android_asset/www/pdfjs/web/viewer.js (985)
Here is my code:
class PDFViewerLocalActivity : AppCompatActivity() {
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
setContentView(R.layout.pdfviewer_layout)
val webView = findViewById(R.id.pdfViewer) as WebView
webView.settings.javaScriptEnabled = true
webView.settings.allowFileAccessFromFileURLs = true
webView.settings.allowUniversalAccessFromFileURLs = true
webView.settings.builtInZoomControls = true
webView.webChromeClient = WebChromeClient()
webView.loadUrl("file:///android_asset/www/pdfjs/web/viewer.html?file=tracemonkey.pdf")
}
}

Okay, this was a dumb question. I already put the following permissions in the manifest:
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />
But forgot that for API 23 and above you have to request permission at run time. So, just added the code to request permissions and it worked.
@TargetApi(23)
fun askPermissions() {
val permissions = arrayOf("android.permission.READ_EXTERNAL_STORAGE", "android.permission.WRITE_EXTERNAL_STORAGE")
val requestCode = 200
requestPermissions(permissions, requestCode)
}
