Now that you have everything prepared let’s explore the methods to update your Java version on Android Studio.
Method 1: Updating via Android Studio SDK Manager
Updating the Java version on Android Studio using the SDK Manager is the most straightforward method. Follow the steps below to update Java through this method:
Step 1: Launch Android Studio.
Step 2: Click on the “SDK Manager” icon on the toolbar or navigate to “Settings > Appearance & Behavior > System Settings > Android SDK.”
Step 3: In the SDK Manager, select the “SDK Tools” tab.
Step 4: Look for the “Android SDK Build-Tools” and check the box next to the latest version.
Step 5: Scroll down and find the “SDK Platform” section. Check the box next to the latest Android version.
Step 6: Click on the “Apply” button to start the update process. Android Studio will download and install the necessary components.
Step 7: Once the update is complete, restart Android Studio to apply the changes.
Pros:
1. Straightforward process through the familiar user interface of Android Studio.
2. Updates not only the Java version but also other necessary components like the Android SDK Build-Tools and SDK Platform.
Cons:
1. Limited control over the Java version being updated, as Android Studio manages it alongside other components.
Method 2: Manually Updating the JDK
If you prefer more control over the Java version being updated or want to update the JDK separately from Android Studio, you can use this method. Follow the steps below to manually update the JDK:
Step 1: Visit the Oracle website (www.oracle.com) and navigate to the Java SE Development Kit (JDK) download page.
Step 2: Accept the license agreement and choose the appropriate JDK version for your operating system.
Step 3: Download the JDK installer and run it.
Step 4: Follow the on-screen instructions to install the JDK.
Step 5: Once the installation is complete, open Android Studio.
Step 6: Go to “File > Project Structure” or press “Ctrl + Alt + Shift + S” to open the Project Structure dialog.
Step 7: Under the “SDK Location” tab, locate the “JDK Location” field.
Step 8: Click on the folder icon next to the field and navigate to the directory where you installed the JDK.
Step 9: Select the JDK directory and click on the “OK” button to save the changes.
Pros:
1. Provides more control over the Java version being updated, allowing you to choose a specific JDK version.
2. Allows updating the JDK separately from Android Studio, enabling you to use the updated JDK across multiple development environments.
Cons:
1. Requires manual downloading and installation of the JDK, which may be unfamiliar to some developers.
2. Involves additional steps compared to updating through the SDK Manager.
Method 3: Updating via Gradle Configuration
Another method to update the Java version on Android Studio is by modifying the Gradle configuration of your project. This method can be useful if you want to update the Java version for a specific project without impacting other projects or your development environment. Follow the steps below to update Java via Gradle configuration:
Step 1: Open your project in Android Studio.
Step 2: Locate the “build.gradle” file in the root directory of your project.
Step 3: Open the “build.gradle” file using a text editor.
Step 4: Find the “android” block in the file.
Step 5: Inside the “android” block, add the following lines of code:
“`
compileOptions {
sourceCompatibility JavaVersion.VERSION_1_8
targetCompatibility JavaVersion.VERSION_1_8
}
“`
Step 6: Save the changes and sync your project with Gradle by clicking on the “Sync Now” button or selecting “File > Sync Project With Gradle Files” from the menu.
Pros:
1. Allows updating the Java version on a per-project basis without affecting other projects or the global Android Studio configuration.
2. Provides flexibility in choosing the Java version for each individual project.
Cons:
1. Requires manual modification of the project’s Gradle configuration file, which may be unfamiliar to some developers.
2. Limited to updating the Java version for a specific project.
Method 4: Updating via Command Line
If you prefer a command-line interface or need to update the Java version on a remote or headless server, you can use the command-line approach. Here’s how you can update the Java version via the command line:
Step 1: Open a terminal or command prompt.
Step 2: Navigate to the directory where Android Studio is installed.
Step 3: Locate the “sdkmanager” command-line tool. It is usually located in the “tools/bin” directory.
Step 4: Run the following command to update the Java version:
“`
sdkmanager –list –verbose
“`
Step 5: Look for the Java Development Kit (JDK) package in the list of available packages.
Step 6: Note the package name for the desired JDK version.
Step 7: Run the following command to install the updated JDK:
“`
sdkmanager –install “package_name”
“`
Replace “package_name” with the actual package name noted in the previous step.
Pros:
1. Offers a command-line approach for updating the Java version, suitable for remote or headless environments.
2. Provides precise control over the JDK package being installed.
Cons:
1. Requires familiarity with the command-line interface, which may not be preferred by all developers.
2. Involves manual installation and potential system-specific dependencies.
