Android Studio is a powerful Integrated Development Environment (IDE) that allows developers to create applications for Android devices. When working with Android Studio, the default setting for the Minimum SDK version is usually set to one of the latest versions. However, in some cases, you may need to change the minimum SDK to an older version.
In this blog post, we will explore how to change the minimum SDK on Android Studio. We will provide you with several methods to do so, along with their pros and cons. We will also look at why you might need to change the minimum SDK and provide some additional tips to help ensure a smooth development process.

The Challenge of Changing the Minimum SDK on Android Studio
Changing the minimum SDK on Android Studio can be challenging, as it requires you to modify certain aspects of your project. This can be especially true if you have already created a project with a specific minimum SDK and have begun writing code.
The main challenge is ensuring that the code you have written is compatible with the new minimum SDK you have chosen. This requires careful analysis and testing to ensure that your code is still functional after the changes have been made.
Things You Should Prepare for
Before we dive into the methods for changing the minimum SDK, there are a few things you should prepare for to ensure a smooth process:
- Backup your project: Before making any changes, it is always a good practice to backup your project to avoid losing any of your work.
- Understand compatibility issues: Changing the minimum SDK can result in compatibility issues with certain APIs and libraries. Be sure to research and test your code thoroughly to ensure compatibility with your chosen minimum SDK.
- Identify dependencies: If your project has any dependencies on specific SDK versions, be sure to identify them and make the necessary changes to ensure compatibility.
Method 1: Changing Minimum SDK via Project Structure
The first method for changing the minimum SDK on Android Studio is through the Project Structure settings. This method is straightforward and can be done in just a few steps:
1. Open your project in Android Studio.
2. Click on the “File” menu and select “Project Structure”.
3. In the Project Structure dialog, select “app” from the left-hand panel.
4. Under “Modules”, select “app”.
5. In the “Properties” tab, locate the “Compile SDK Version” and “Minimum SDK Version” fields.
6. Change the “Minimum SDK Version” to your desired value.
7. Click “OK” to save your changes.
Pros:
- Straightforward method
- Allows for easy modification of the minimum SDK version for your entire project
Cons:
- May result in compatibility issues with certain APIs and libraries
- Does not address issues related to code compatibility
Method 2: Changing Minimum SDK via Gradle Build File
The second method for changing the minimum SDK on Android Studio is through the Gradle build file. This method allows you to modify the minimum SDK version for specific modules or libraries within your project:
1. Open your project in Android Studio.
2. Locate the build.gradle file for the module you want to modify.
3. Locate the “minSdkVersion” attribute and change its value to your desired minimum SDK version.
4. Sync your project with Gradle by clicking on the “Sync Now” button in the toolbar.
Pros:
- Allows for modification of the minimum SDK version for specific modules or libraries within your project
- Allows for more granular control over your project’s minimum SDK version
Cons:
- May result in compatibility issues with certain APIs and libraries
- Requires knowledge of Gradle build file structure
Method 3: Changing Minimum SDK via Manifest File
The third method for changing the minimum SDK on Android Studio is through the manifest file. This file defines the minimum SDK version required for your application to run:
1. Open your project in Android Studio.
2. Locate the AndroidManifest.xml file for your project.
3. Locate the “minSdkVersion” attribute and change its value to your desired minimum SDK version.
4. Save the file and rebuild your project.
Pros:
- Allows for quick modification of the minimum SDK version
- User-friendly method for developers who are not as familiar with the Gradle build file structure
Cons:
- May result in compatibility issues with certain APIs and libraries
- Requires careful analysis and testing to ensure code compatibility
Why Can’t I Change the Minimum SDK?
There are a few reasons why you may not be able to change the minimum SDK on Android Studio:
1. Dependent libraries: Some libraries require a specific minimum SDK version and cannot be modified. In this case, you may need to consider alternative libraries if the current one is not compatible with your minimum SDK version.
2. Code compatibility: Your project’s code may not be compatible with the minimum SDK version you are trying to change it to. In this case, you will need to analyze and test your code to ensure compatibility before making any changes.
3. Deprecated APIs: Some APIs are deprecated in newer versions of the SDK, meaning that they are no longer supported or may not function as intended. In this case, you may need to modify your code to use alternative APIs.
Additional Tips
To ensure a smooth process when changing the minimum SDK on Android Studio, here are some additional tips:
- Test your code thoroughly: Be sure to test your code thoroughly to ensure that it is compatible with the minimum SDK version you have chosen.
- Stay up-to-date: Keep your project up-to-date with the latest versions of the SDK and APIs to minimize issues related to compatibility and deprecated APIs.
- Keep documentation: Keep documentation of your process and any changes made to ensure that you can easily trace any issues that may arise.
5 FAQs about Changing Minimum SDK on Android Studio
Q1: Can I change the minimum SDK for only one activity?
A: Yes, you can change the minimum SDK for only one activity by modifying the activity’s manifest file. Locate the “minSdkVersion” attribute and change its value to your desired minimum SDK version.
Q2: What happens if I set the minimum SDK version too low?
A: Setting the minimum SDK version too low may result in compatibility issues with newer APIs and functionality. You may need to modify your code to use alternative APIs.
Q3: Can I change the minimum SDK version after publishing my app?
A: Yes, you can change the minimum SDK version after publishing your app. However, be sure to test your code thoroughly to ensure compatibility with the chosen minimum SDK version.
Q4: How can I check the compatibility of my code with a new minimum SDK version?
A: You can check your code’s compatibility with a new minimum SDK version by running tests and analyzing your code. Be sure to test all aspects of your application thoroughly to ensure compatibility.
Q5: What should I do if I encounter issues related to deprecated APIs?
A: If you encounter issues related to deprecated APIs, you may need to modify your code to use alternative APIs or libraries. Be sure to research and test any changes thoroughly to ensure compatibility.
