"`
defaultConfig {
…
minSdkVersion 21
…
}
"`
4. Modify the value of minSdkVersion to the desired API level. For example, if you want to target Android 10 (API level 29), change the line to:
"`
minSdkVersion 29
"`
5. Sync your project with Gradle by clicking the "Sync Now" button or selecting "Sync Project with Gradle Files" from the "File" menu.
