android - Can't open a local PDF in webview using file:// -


i need display pdf file located in app dir in webwiev without using google docs.

this code webview:

public void openpdf() { webview webview = new webview(this);      setcontentview(webview);     webview.getsettings().setjavascriptenabled(true);      webview.loadurl("file://mnt/data/data/com.example.android/files/docs/test.pdf");; }

i blank webview instead of below code works

public void openpdf() { webview webview = new webview(this);      setcontentview(webview);     webview.getsettings().setjavascriptenabled(true);      webview.loadurl("file://mnt/data/data/com.example.android/files/docs/test.html");   }

i tested directly in web browser file://mnt/data/data/com.example.android/files/docs/test.pdf , test.html , worked both. installed pdf reader.

any ideas why pdf files won't open ?

their seems answer question in stack overflow @ open local html file in webview - android

to sum : usage of file:/// before actual path should solve problem except .pdf files

webview not support pdf in android :(. need use google doc according different sources.
