SMS Cleaner

简体中文 | 繁體中文 | English

• SMS Cleaner is a tool for reading and batch deleting SMS messages on Android, built with Flutter framework.
• Although the UI framework Flutter supports cross-platform development, only Android SMS deletion functionality has been implemented.

• Get SMS permissions
• Copy SMS to clipboard
• Set/restore default SMS app
• Filter SMS messages by keywords
• Search SMS by phone number
• Remove/directly delete SMS from search results
• One-click batch deletion of queried SMS messages
• One-click export of all SMS messages to CSV file

• Flutter 3.44.9 (stable)
• Dart 3.12.2
• Gradle 9.1.0
• Android Gradle Plugin 9.0.1
• Kotlin 2.3.20
• compileSdk 36 / minSdk 26
• JDK 17

Build the release APK with flutter_distributor:

dart pub global activate flutter_distributor
flutter_distributor release --name apk

Artifacts are output to dist/. The APK is signed with the release keystore and packages arm64-v8a only (single ABI).

• permission_handler is pinned to 12.0.3: v13 requires compileSdk 37, which exceeds the Flutter stable template (compileSdk 36) and AGP 9.0.1's supported range.
• Old plugins (e.g. sms_advanced 1.1.0, from the AGP 4.1 era) lack a namespace and hardcode compileSdk 31. The root android/build.gradle.kts auto-fills the namespace from project.group and raises the compileSdk of legacy library modules to 36.
• Lint tasks are disabled in android/build.gradle.kts (see the Call project note): legacy plugin buildscripts pin old AGP versions and crash the lint worker (AndroidLintWorkAction) when mixed with root AGP 9.0.1; extract*Annotations tasks are replaced with placeholder outputs.
• kotlin.incremental=false is set in android/gradle.properties: on Windows, Kotlin incremental compilation cannot handle sources (pub cache on the C: drive) and build output (project on the D: drive) on different drives.
• sms_advanced applies the Kotlin Gradle Plugin itself; future Flutter versions will reject this, so keep an eye out for an alternative.
• Code quality is guaranteed by dart analyze in CI.
