I am developing web based application, in which I am overriding
shouldInterceptRequest of WebViewClient as shown below.
public WebResourceResponse shouldInterceptRequest(WebView view, String
url)
{
WebResourceResponse response = null;
if(url.startsWith("myscheme://"))
{
String MY_CONTENT_PROVIDER_URI = "content://
android.sunil.myprovider/";
String myurl = MY_CONTENT_PROVIDER_URI + url;
String mimeType = null;
String encoding = "utf-8";
int mimeIndex = myurl.lastIndexOf('?');
if (mimeIndex != -1)
{
myurl= myurl.substring(0, mimeIndex);
mimeType = "text/html";
}
Uri myuri= Uri.parse(myurl);
InputStream wrtInputStream =
mContext.getContentResolver().openInputStream(myuri); response = new
MyWebResourceResponse(mimeType,encoding,wrtInputStream);
}
else
response = super.shouldInterceptRequest(view,url);
return response;
}
// My Content Provider OpenFile function is defined as:::
public ParcelFileDescriptor openFile(Uri uri, String mode) throws
FileNotFoundException
{
String filename = uri.toString();
filename = filename.replace("myscheme://","/mnt/sdcard/");
return ParcelFileDescriptor.open(new File(filename),
ParcelFileDescriptor.MODE_READ_ONLY);
}
Now from my app I am calling WebView.loadUrl("myscheme://mywebfolder/
index.html") and mywebfolder is placed in mnt/sdcard which is resolved
in my content provider as shown above.
Now problem arises when count for call of loadUrl increases beyond
510 then my app crashes with the given log::
