Let\u2019s go through the details of the content provider in Android through this article, but first, let&#8217;s take a glance of topics that we will discuss:<\/p>\n<ul>\n<li>What are Content Providers<\/li>\n<li>CRUD operations<\/li>\n<li>Examples<\/li>\n<li>Accessing data with Content provider<\/li>\n<li>Implementing Content Provider<\/li>\n<\/ul>\n<h3>What are Content Providers in Android?<\/h3>\n<p>Content Providers are an important component of Android. They handle the access to the central repository and supply data from one application to another on request. This task of handling is done by methods of <strong>ContentResolver<\/strong> class. So, content providers can store data in various ways such as files, database or over the internet.<\/p>\n<p>Many a time we need to share our data with applications and that\u2019s where it becomes useful. The following diagram depicts how the content provider helps in sharing data with applications from data stores.<\/p>\n<p><a href=\"https:\/\/data-flair.training\/blogs\/wp-content\/uploads\/sites\/2\/2020\/02\/content-provider-in-android.jpg\"><img loading=\"lazy\" decoding=\"async\" class=\"aligncenter size-full wp-image-75509\" src=\"https:\/\/data-flair.training\/blogs\/wp-content\/uploads\/sites\/2\/2020\/02\/content-provider-in-android.jpg\" alt=\"content provider in android\" width=\"802\" height=\"420\" srcset=\"https:\/\/data-flair.training\/blogs\/wp-content\/uploads\/sites\/2\/2020\/02\/content-provider-in-android.jpg 802w, https:\/\/data-flair.training\/blogs\/wp-content\/uploads\/sites\/2\/2020\/02\/content-provider-in-android-150x79.jpg 150w, https:\/\/data-flair.training\/blogs\/wp-content\/uploads\/sites\/2\/2020\/02\/content-provider-in-android-300x157.jpg 300w, https:\/\/data-flair.training\/blogs\/wp-content\/uploads\/sites\/2\/2020\/02\/content-provider-in-android-768x402.jpg 768w, https:\/\/data-flair.training\/blogs\/wp-content\/uploads\/sites\/2\/2020\/02\/content-provider-in-android-520x272.jpg 520w\" sizes=\"auto, (max-width: 802px) 100vw, 802px\" \/><\/a><\/p>\n<p>As can be seen, the content provider lets us collect the data centrally and provide them to applications as shown in the above diagram. Content providers act the same as database and also we can query it to add, delete, insert or update the data.<\/p>\n<p>It can be understood that a content provider hides the database details and also, it lets an application share data among other applications. Content providers are not limited to texts, but also contains images and videos as well.<\/p>\n<h3>CRUD Operations<\/h3>\n<p>Content providers provide the following four basic operations. These are also known as CRUD operations, where<\/p>\n<p><strong>C &#8211; Create<\/strong><br \/>\n<strong>R &#8211; Read<\/strong><br \/>\n<strong>U &#8211; Update<\/strong><br \/>\n<strong>D &#8211; Delete<\/strong><\/p>\n<p>The above are the four operations of content providers :<\/p>\n<ul>\n<li><strong>Create:<\/strong> It is used for the creation of data in content providers.<\/li>\n<li><strong>Read:<\/strong> It reads the data stored in the content provider.<\/li>\n<li><strong>Update:<\/strong> It lets the editing in existing data in content providers.<\/li>\n<li><strong>Delete:<\/strong> It deletes the existing data stored in its Storage.<\/li>\n<\/ul>\n<h3>Examples of Android Content Providers<\/h3>\n<p>To understand content providers with examples, consider the following examples :<\/p>\n<ul>\n<li>The Gallery that contains images.<\/li>\n<li>Contact lists that contain Contact details.<\/li>\n<li>A dictionary that has collections of all the words that are used.<\/li>\n<li>The music playlist has a list of songs.<\/li>\n<li>Call logs contain the call details.<\/li>\n<\/ul>\n<p>This is how exactly content providers work.<\/p>\n<p><a href=\"https:\/\/data-flair.training\/blogs\/wp-content\/uploads\/sites\/2\/2020\/02\/working-of-android-content-provider.jpg\"><img loading=\"lazy\" decoding=\"async\" class=\"aligncenter size-full wp-image-75504\" src=\"https:\/\/data-flair.training\/blogs\/wp-content\/uploads\/sites\/2\/2020\/02\/working-of-android-content-provider.jpg\" alt=\"working of android content provider\" width=\"648\" height=\"414\" srcset=\"https:\/\/data-flair.training\/blogs\/wp-content\/uploads\/sites\/2\/2020\/02\/working-of-android-content-provider.jpg 648w, https:\/\/data-flair.training\/blogs\/wp-content\/uploads\/sites\/2\/2020\/02\/working-of-android-content-provider-150x96.jpg 150w, https:\/\/data-flair.training\/blogs\/wp-content\/uploads\/sites\/2\/2020\/02\/working-of-android-content-provider-300x192.jpg 300w, https:\/\/data-flair.training\/blogs\/wp-content\/uploads\/sites\/2\/2020\/02\/working-of-android-content-provider-520x332.jpg 520w\" sizes=\"auto, (max-width: 648px) 100vw, 648px\" \/><\/a><\/p>\n<h3>Accessing Data with Content Provider<\/h3>\n<p>We need to use the <strong>ContentResolver<\/strong> object in our application, in order to communicate with the content providers for data access. Now to enable communication between the user interface and ContentResolver, we use another object, <strong>CursorLoader<\/strong> to run query asynchronously. This CursorLoader will be called using Activity\/Fragment of the application.<\/p>\n<p>Then, the content provider receives the query from the client and executes and returns the result.<\/p>\n<p>To understand how it works, consider the following diagram:<\/p>\n<p><a href=\"https:\/\/data-flair.training\/blogs\/wp-content\/uploads\/sites\/2\/2020\/02\/accessing-data-with-android-content-provider.jpg\"><img loading=\"lazy\" decoding=\"async\" class=\"aligncenter size-full wp-image-75505\" src=\"https:\/\/data-flair.training\/blogs\/wp-content\/uploads\/sites\/2\/2020\/02\/accessing-data-with-android-content-provider.jpg\" alt=\"accessing data with android content provider\" width=\"385\" height=\"684\" srcset=\"https:\/\/data-flair.training\/blogs\/wp-content\/uploads\/sites\/2\/2020\/02\/accessing-data-with-android-content-provider.jpg 385w, https:\/\/data-flair.training\/blogs\/wp-content\/uploads\/sites\/2\/2020\/02\/accessing-data-with-android-content-provider-84x150.jpg 84w, https:\/\/data-flair.training\/blogs\/wp-content\/uploads\/sites\/2\/2020\/02\/accessing-data-with-android-content-provider-169x300.jpg 169w\" sizes=\"auto, (max-width: 385px) 100vw, 385px\" \/><\/a><\/p>\n<p><em><strong>Wait!

A content URI includes two things:\u00a0<strong>Authority<\/strong> that is the symbolic name of the Provider and a <strong>Path<\/strong> that is a name that points towards the data. Every content provider methods have an argument which is <a href=\"https:\/\/developer.android.com\/reference\/java\/net\/URI\">URI<\/a>.<\/p>\n<p>Let&#8217;s understand the Content Provider URI:<\/p>\n<pre class=\"EnlighterJSRAW\" data-enlighter-language=\"null\">content:\/\/&lt;authority&gt;\/&lt;path&gt;\/&lt;optional_id&gt;<\/pre>\n<ul>\n<li><strong>content:\/\/ &#8211;<\/strong>\u00a0It\u2019s always present, and is the scheme portion of the URI.<\/li>\n<li><strong>authority &#8211;<\/strong>\u00a0It is the unique name of the content provider, like photos, contacts. It\u2019s a string that can identify the whole content provider.<\/li>\n<li><strong>path &#8211;<\/strong>\u00a0It is often used to identify some or the other data of the provider. The path is mostly used to identify individual tables.<\/li>\n<li><strong>optional_id &#8211;<\/strong>\u00a0id is used to access a single particular record of a file. We use this only in cases where we need to access only a particular record and not the complete file. It\u2019s a numeric identifier to access a particular row of the data table.<\/li>\n<\/ul>\n<p>Content provider also has two wildcards which are:<\/p>\n<ol>\n<li><strong>* &#8211;<\/strong>\u00a0Asterisk (*) is used to match valid characters irrespective of their length.<\/li>\n<li><strong>#\u00a0&#8211;<\/strong> Hash (#) is used to match valid numerals irrespective of their length.<\/li>\n<\/ol>\n<h2>Implementation of Content Provider in Android<\/h2>\n<p>We\u2019ll create a file named ContentProvider and within that, we\u2019ll create a Java file of name <strong>DataFlairProvider.java<\/strong>.
