Upgrading Android Target API from Level 33 to Level 34/Higher: A Step-by-Step Guide

Preparing for the Upgrade

Before we dive into the upgrade process, make sure you have the following:

• A compatible Android development environment (e.g., Android Studio, IntelliJ IDEA)
• A project with a minimum SDK version of 33 or higher
• A keen understanding of Android development concepts (e.g., Gradle, AndroidManifest.xml)

Step 1: Update Your Project Structure

In your project’s root directory, locate the `build.gradle` file and update the `compileSdkVersion` and `targetSdkVersion` to the desired API level (e.g., 34 or higher):

android {
    compileSdkVersion 34
    defaultConfig {
        applicationId "com.example.myapp"
        minSdkVersion 21
        targetSdkVersion 34
        versionCode 1
        versionName "1.0"
    }
    ...
}

Step 2: Update Your AndroidManifest.xml

In your app’s `AndroidManifest.xml` file, update the `android:targetSdkVersion` attribute to match the new API level:

<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.example.myapp">

    <uses-sdk android:minSdkVersion="21" android:targetSdkVersion="34" />

    <application
        android:allowBackup="true"
        android:icon="@mipmap/ic_launcher"
        android:label="@string/app_name"
        android:supportsRtl="true"
        android:theme="@style/AppTheme">
        ...
    </application>

</manifest>

Step 3: Update Your Gradle Dependencies

In your project’s `build.gradle` file, ensure that you’re using the latest version of the Android Gradle plugin and the Android Support Library:

buildscript {
    repositories {
        jcenter()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:4.1.2'
    }
}

allprojects {
    repositories {
        jcenter()
    }
}

dependencies {
    implementation 'androidx.appcompat:appcompat:1.3.1'
    implementation 'androidx.constraintlayout:constraintlayout:2.0.2'
    ...
}

Step 4: Update Your Code and Fix Compatibility Issues

With the project structure and Gradle dependencies updated, it’s time to review your code and address any compatibility issues:

• Deprecated APIs**: Identify and replace deprecated APIs with their newer counterparts.
• Permission Changes**: Review and update your app’s permission handling to comply with the new API level’s requirements.
• Behavioral Changes**: Be aware of behavioral changes in the new API level and update your code accordingly.
