Pick Contact - Android Studio - Java

-

Implement the Contact Pick feature in and Android App

To allow the user to pick a contact from the phone's contacts list, we can use contact intent. You will get all information of the contact e.g. Name, Phone Number(s), Address, Thumbnail, Email, etc. You can use get the specific information according to your requirement. To pick a contact we need to READ_CONTACTS permission.

Add permission in AndroidManifest.xml:

<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.blogspot.atifsoftwares.pickcontact">

    <!--Read contact permission-->
    <uses-permission android:name="android.permission.READ_CONTACTS"/>

    <application

Picture In Picture - Android Studio - Kotlin

How to add Picture In Picture Mode in the Android app? Android 8.0 (API level 26) allows activities to launch in the picture-in-picture (PIP) mode. PIP is a special type of multi-window mode mostly used for video playback. It lets the user watch a video in a small window pinned to a corner of the screen while navigating between apps or browsing content on the main screen. The PIP window appears in the top layer of the screen in a corner chosen by the system. >> Check For Java >> Check For Kotlin >> Check For Compose Video: Step 1:  Create a new project   or   open an existing project Step 2: Create another activity named PIPActivity Step 3: Add the following properties to the PIPActivity in AndroidManifest <activity android:name= ".PIPActivity" android:configChanges= "screenSize|smallestScreenSize|screenLayout|orientation" android:launchMode= "singleTask" android:resizeableActivity= "tr...

Manage External Storage Permission - Android Studio - Kotlin

Image
Manage External Storage Permission Previously (before Android 11), we only needed to request the WRITE_EXTERNAL_STORAGE Permission to perform the storage-related tasks. However, for Android 11 and above, we must request the MANAGE_EXTERNAL_STORAGE Permission to perform storage-related tasks. Keep in mind that if you're 100% certain that your app requires this permission to function properly, then request it; otherwise, Google will not allow you to publish/update your app. For example, if your app is WhatsApp Status Saver, then you won't be allowed to use this permission as your app works with images and videos, not files. After permission is granted, I'll input a name and create a folder with that name, just for example. You can do whatever you want instead. >> Check For Java >> Check For Kotlin >> Check For Compose Video Tutorial: Coding: AndroidManifest.xml <?xml version="1.0" encoding="utf-8"?> <manifest xmlns:android= ...

SeekBar with Customization | Android Studio | Java

-
Image
 SeekBar A SeekBar widget is an extension of the widget ProgressBar that adds a draggable thumb. The user can touch the thumb and drag right or left to change the current progress level or use the arrow keys to do the same. You may have seen photo editing apps having features to change the brightness level, blur level, and contrast level. They use SeekBar to change these options.  In this tutorial we will not only learn to use the SeekBar we will also learn how to customize for example its thumb size, color, and background. >>Check For Kotlin<< . Simple SeekBar Let's implement the Simple Seekbar without any customization and handle the progress change listener. I'm just showing progress in TextView, you can do whatever you want. activity_main.xml <?xml version="1.0" encoding="utf-8"?> <RelativeLayout xmlns:android= "http://schemas.android.com/apk/res/android" xmlns:app= "http://schemas.android.com/apk/res-auto"...
