Nowadays we see many applications are made to compress videos and other files so that users can save memory as well as maintain the quality of that file. In this article, we are going to see how we can compress videos in the android studio and can make our own video compressing application.
What we are going to build in this article?
Below is a sample video of a video compressor that we are going to build in this article. Note that we are going to implement this project using the Java language.
Step by Step Implementation
Step 1: Create a new project
- Open a new project.
- We will be working on Empty Activity with language as Java. Leave all other options unchanged.
- You can change the name of the project at your convenience.
- There will be two default files named activity_main.xml and MainActivity.java.
If you don’t know how to create a new project in Android Studio then you can refer to How to Create/Start a New Project in Android Studio?
Step 2: Adding required dependencies
Open Gradle Scripts > build.gradle(module). and use the following dependencies in it-
implementation 'com.iceteck.silicompressorr:silicompressor:2.2.4' implementation 'com.googlecode.mp4parser:isoparser:1.1.22'
Click on sync now to save the changes.
Step 3: Adding required permissions
Open the AndroidManifest.xml file and add the following permissions to it-
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE"/> <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>
Step 4: Working with xml files
Navigate to the app > res > layout > activity_main.xml and add the below code to that file. Below is the code for the activity_main.xml file.
<? xml version = "1.0" encoding = "utf-8" ?>
< LinearLayout
android:layout_width = "match_parent"
android:layout_height = "match_parent"
android:orientation = "vertical"
android:padding = "16dp"
android:gravity = "center_horizontal"
tools:context = ".MainActivity" >
< Button
android:layout_width = "match_parent"
android:layout_height = "wrap_content"
android:id = "@+id/bt_select"
android:text = "Select Video" />
< RelativeLayout
android:layout_width = "match_parent"
android:layout_height = "wrap_content"
android:clipToPadding = "false"
android:fitsSystemWindows = "true" >
< VideoView
android:layout_width = "match_parent"
android:layout_height = "180dp"
android:id = "@+id/video_view1"
android:visibility = "gone" />
</ RelativeLayout >
< TextView
android:layout_width = "wrap_content"
android:layout_height = "wrap_content"
android:id = "@+id/TextView1"
android:text = "Original Video"
android:textSize = "20sp"
android:textStyle = "bold"
android:visibility = "gone"
android:layout_marginTop = "8dp" />
< RelativeLayout
android:layout_width = "match_parent"
android:layout_height = "wrap_content"
android:clipToPadding = "false"
android:fitsSystemWindows = "true" >
< VideoView
android:layout_width = "match_parent"
android:layout_height = "180dp"
android:id = "@+id/Video_view2"
android:visibility = "gone"
android:layout_marginTop = "32dp" />
</ RelativeLayout >
< TextView
android:layout_width = "wrap_content"
android:layout_height = "wrap_content"
android:id = "@+id/text_view2"
android:text = "Compressed Video"
android:textSize = "20sp"
android:textStyle = "bold"
android:visibility = "gone"
android:layout_marginTop = "8dp" />
< TextView
android:layout_width = "wrap_content"
android:layout_height = "wrap_content"
android:id = "@+id/TextView3"
android:textSize = "16sp"
android:visibility = "gone"
android:layout_marginTop = "4dp" />
</ LinearLayout >

Step 5: Working with java files
Go to the MainActivity.java file and refer to the following code. Below is the code for the MainActivity.java file. Comments are added inside the code to understand the code in more detail.
package com.example.videocompress;

.show();
}
}
@Override
protected void onActivityResult( int requestCode,
int resultCode,
@Nullable Intent data)
{
super .onActivityResult(requestCode, resultCode,
data);
// Check condition
if (requestCode == 100 && resultCode == RESULT_OK
&& data != null ) {
// When result is ok
// Initialize Uri
Uri uri = data.getData();
// Set video uri
videoView1.setVideoURI(uri);
// Initialize file
File file = new File(
Environment.getExternalStorageDirectory()
.getAbsolutePath());
// Create compress video method
new CompressVideo().execute(
"false" , uri.toString(), file.getPath());
}
}
private class CompressVideo
extends AsyncTask<String, String, String> {
// Initialize dialog
Dialog dialog;
@Override protected void onPreExecute()
{
super .onPreExecute();
// Display dialog

}
@Override
protected String doInBackground(String... strings)
{
// Initialize video path
String videoPath = null ;
try {

Uri uri = Uri.parse(strings[ 1 ]);
// Compress video
videoPath
= SiliCompressor.with(MainActivity. this )
.compressVideo(uri, strings[ 2 ]);
}
catch (URISyntaxException e) {
e.printStackTrace();
}
// Return Video path
return videoPath;
}
@Override protected void onPostExecute(String s)
{
super .onPostExecute(s);
// Dismiss dialog
dialog.dismiss();
// Visible all views
videoView1.setVisibility(View.VISIBLE);
textView1.setVisibility(View.VISIBLE);
videoView2.setVisibility(View.VISIBLE);
textView2.setVisibility(View.VISIBLE);
textView3.setVisibility(View.VISIBLE);
// Initialize file
File file = new File(s);
// Initialize uri
Uri uri = Uri.fromFile(file);
// set video uri
videoView2.setVideoURI(uri);
// start both video
videoView1.start();
videoView2.start();
// Compress video size
float size = file.length() / 1024f;
// Set size on text view
textView3.setText(
String.format( "Size : %.2f KB" , size));
}
}

Here is the final output of our application.
