I am trying to load my HTML files from Android expansion file(.obb) using WebView like
String prompt = "";
WebView webview = (WebView) rootView.findViewById(R.id.webview);
try {
InputStream html = getAssetFileDescriptor("www/" + mResult.getTitle() + ".html")
.createInputStream();
byte[] b = new byte[html.available()];
html.read(b);
prompt = new String(b);
html.close();
} catch (IOException e) {
Log.e("Webview", "Couldn't open webpage");
}
webview.loadData(prompt, "text/html", "utf-8");
*getAssetFileDescriptor returns InputStream read by ZipResourceFile function(Zip file library)
It loads HTML into Webview successfully but all the images inside the HTML are not appearing.
I guess It's because it cannot access to image files through img tags.
for example, my html files have img tags like
<img src="./image1.jpg" />
Relative path seems not working because html and image files are zipped into obb file.
How can I fix it?
You can mount the OBB file using StorageManager:
StorageManager storageManager = (StorageManager)app.getSystemService(Context.STORAGE_SERVICE);
boolean queued = storageManager.mountObb(<path>, null, new OnObbStateChangeListsner() {...});
Then, you can use this path to construct a path to your files: the returned path is the root to your OBB:
storageManager.getMountedObbPath(...) + "/image1.jpg";
an use that path to load your image
<img src="your_path" />
