Downloads

• abCheck-1.3.0.apk: signed, minified Android APK for direct installation.
• abCheck-1.3.0-code10-signed.aab: Google Play upload bundle, not directly installable.
• abCheck-1.3.0-screenshots.zip: full screen inventory captured from the running app on an Android emulator.

Android 8.0+ (API 26), target API 36. Package: com.abanana.abattery. Version code: 10.

The GitHub APK uses the project's current upload certificate. Its certificate differs from Google Play's app-signing certificate and may differ from older GitHub builds. Keep using the same installation channel; Android will reject an in-place update across different signing certificates. Export any needed local history before changing installation channels.

Google Play publication requires Google review. This GitHub release does not mean the Play update is already available.

Screenshots show actual emulator readings. Physical hardware accuracy and OEM-specific data still require real-device testing. Unavailable readings are not replaced with invented values.

abCheck 1.2.0 - foreground service review evidence

Foreground service demonstration for abCheck Device & System 1.2.0 (com.abanana.abattery).

This is review evidence recorded on an Android API 36 emulator, not a new application binary. The recording shows the user starting the floating diagnostic monitor, viewing it above the launcher, and stopping it through the persistent notification. It then shows user-started local battery recording and its notification Stop action. CPU frequency is unavailable on the emulator; no hardware values are fabricated. The device has no personal accounts or private user content in the recording.
