Ionic and Capacitor generally aim to support a wide range of Android versions, but there can be limitations based on the libraries and plugins you are using, as well as the minimum SDK version specified in your project.
Minimum SDK Version: Check the build.gradle file in your Android project (usually located at android/app/build.gradle). Look for the minSdkVersion setting. If it's set to a value higher than 24 (which corresponds to Android 7), your app won't run on Android 7 devices.
Plugin Compatibility: Some Capacitor plugins may require a minimum version higher than Android 7. Review the documentation for any plugins you are using to ensure they support Android 7.
WebView Compatibility: Older Android versions use older WebView implementations, which may not support newer JavaScript features or CSS. Ensure that your app's code is compatible with older browsers. Testing on Real Device: Sometimes, emulators can behave differently than real devices. If possible, test on a physical Android 7 device to see if the issue persists.
