Implementing Picture-in-Picture (PiP) on Android requires specific steps. Here's a simple Kotlin example showing how to enable and handle PiP mode in an Android app.
First, make sure your app targets at least API level 24 (Android Nougat) or higher, as this is the first version that introduced PiP mode.
Here's a simple Activity example that shows how to set up and handle PiP mode:
package com.example.pipexample
import android.app.PictureInPictureParams
import android.content.res.Configuration
import android.os.Build
import android.os.Bundle
import androidx.appcompat.app.AppCompatActivity
import kotlinx.android.synthetic.main.activity_main.*
class MainActivity : AppCompatActivity() {
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
setContentView(R.layout.activity_main)
// Set up a button to enter picture-in-picture mode
pipButton.setOnClickListener {
enterPIPMode()
}
}
private fun enterPIPMode() {
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
val params = PictureInPictureParams.Builder().build()
enterPictureInPictureMode(params)
} else if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.N) {
enterPictureInPictureMode()
}
}
override fun onUserLeaveHint() {
super.onUserLeaveHint()
enterPIPMode()
}
override fun onPictureInPictureModeChanged(isInPictureInPictureMode: Boolean, newConfig: Configuration?) {
super.onPictureInPictureModeChanged(isInPictureInPictureMode, newConfig)
if (isInPictureInPictureMode) {
// Operations performed after entering picture-in-picture mode
videoView.visibility = VISIBLE
} else {
// Operations to perform after exiting picture-in-picture mode
videoView.visibility = INVISIBLE
}
}
}
You also need to define the UI layout in the `res/layout/activity_main.xml` file, which includes a button to trigger PiP mode and a video view:
<pre>
xml code:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="
http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent">
<VideoView
android:id="@+id/videoView"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:visibility="gone"/>
<Button
android:id="@+id/pipButton"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Enter PIP Mode"/>
</RelativeLayout>
</pre>
Please note that in a real-world project, you may also need to configure the video player and other logic to suit your specific application scenario.

This sample code provides a basic framework to help you implement Picture-in-Picture functionality in your Android app. You may need to further expand and refine this code based on your specific needs.
