一个人想着一个人 提交于 2019-12-03 17:49:59
问题 I have a question that seems easy but I cannot seem to get it to work properly.

I have everything working but I want to set the ProgessBar max value to be the number of files within the zip file. The number of files within this folder will sometimes change so I want the ProgessBar to be relative to how many files are contained within the

How to access local assets from a remote URL in Android WebView?

生来就可爱ヽ(ⅴ<●) 提交于 2019-12-03 17:24:27
To load an asset in HTML, I am using the URL file:///android_asset/my_image.png . It works when I am loading HTML locally, for instance, using a WebView.loadData() method. However, I am unable to load a local asset from a remote web site, for instance, when I load a page using WebView.loadUrl("http://example.com/my_page.html") . It shows the page, but the image is not loaded. How can I fix this problem? UPDATE: tarkeshwar mentioned that it is not possible because of security reasons. I understand when you open a web page in a browser, then you as a user are unable to control what the web page

I am building an application that currently read images from the drawable folder. Since i cannot have subfolders in the drawable i have to create subfolders in the assets folder and load images from there.

My code is this: public class ImageAdapter extends BaseAdapter { private Context mContext; // Keep all Images in array public Integer[] mThumbIds = { R.drawable.pic_2, R.drawable.pic_3, R.drawable.pic_4, R.drawable.pic_5, R.drawable.pic_6, R.drawable.pic_7, R.drawable.pic_8, R.drawable

Keep TensorFlow Model Encrypted on Android

梦想的初衷 提交于 2019-12-03 13:29:30
问题 I searched to understand if there is a technique to keep a trained tensorflow model (.pb file) safe in an Android app but didn't find anything useful. I am releasing an app containing a tensorflow model which I built on a training set. When I release the app, anyone can access the model and use it for his own app. I wonder if there is a way to protect a tensorflow model that I put in the asset folder of my Android application? This is the way that I load my model in Android:

问题 Note this is intended to be a Ask and Answer Your Own Questions as per share your knowledge, Q&A-style Often a pre-existing database is provided for an Android App that utilises SQLite. The database is often placed into the assets folder and the App will copy the database if it does not exist. For a newer version of the App changing the database in the assets folder is fine as the changed database will be copied. However, when upgrading an App from a previous version the database will exist

早过忘川 提交于 2019-12-02 16:29:36
问题 I am in the early stages of putting together an Android app that will host an assets based "website" using NanoHttpd. The app will rely heavily on the jquery library. I am using this NanoHttpd.java file and have successfully hosted and accessed a html file. My problem is that I cannot seem to be able to include a local copy of the jquery library. If I reference a cdn hosted copy, everything works just as it should. If I place a copy of the library in the assets directory, the html of the page
