Use Glide Cache efficiently in Glide Android

The issue is that currently if I call Glide.load() multiple times with the same URL. however, each time with an image views the image gets downloaded again.

It happens because the width and height are mixed into the cache key so if you load the same image into multiple different views with different sizes, the image will be fetched once per image by default.

You can change this by calling  .diskCacheStrategy() with  DiskCacheStrategy.SOURCE on remote image loads. Doing so will use only the original URL as the cache key and so you will get a cache hit if you try to load the same URL with multiple sizes.


    .with( context )
    .load( URL )
    .diskCacheStrategy( DiskCacheStrategy.SOURCE )
    .into( imageViewInternet );

Maintain cookie session in Android(Retrofit)

A session is a sequence of requests made by a single end-user during a visit to a particular site. A session or query session may be all queries made by a user in a particular time period or it may also be a series of queries or navigation with a consistent underlying user need.

In Android, if we use the retrofit for web services call it internally uses OkHttp and OkHttp does not keep the track of session automatically. Generally, the session is maintained using the cookie value that we get in each response we receive.

So, we need to keep the cookie from one call to another. this can be down using CookieManager as follows:

HttpLoggingInterceptor interceptor = new HttpLoggingInterceptor();

CookieHandler cookieHandler = new CookieManager();
OkHttpClient client = new OkHttpClient.Builder().addNetworkInterceptor(interceptor)
.cookieJar(new JavaNetCookieJar(cookieHandler))
.connectTimeout(10, TimeUnit.SECONDS)
.writeTimeout(10, TimeUnit.SECONDS)
.readTimeout(30, TimeUnit.SECONDS)

Retrofit retrofit = new Retrofit.Builder()

for this following dependencies are required:

compile ‘com.squareup.okhttp3:logging-interceptor:3.4.1’
compile ‘com.squareup.okhttp3:okhttp:3.4.1’
compile ‘com.squareup.okhttp3:okhttp-urlconnection:3.6.0’
