From 3bbd50ad923be67f551e7e1ff146f4e42e647d50 Mon Sep 17 00:00:00 2001 From: "google-labs-jules[bot]" <161369871+google-labs-jules[bot]@users.noreply.github.com> Date: Fri, 3 Jul 2026 19:34:59 +0000 Subject: [PATCH] =?UTF-8?q?=F0=9F=8E=A8=20Palette:=20UX=20improvements=20f?= =?UTF-8?q?or=20sample=20app=20and=20Java=2021=20compatibility?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit 💡 What: - Added Toast feedback for all native hook and test operations in MainActivity. - Improved 'load libhookee2.so' button UX: it now disables and updates its text to 'libhookee2.so loaded' after successful loading. - Upgraded Gradle to 8.5 and AGP to 8.2.2. - Updated javaVersion to 1.8 in build.gradle. 🎯 Why: - Operations that previously occurred silently now provide immediate feedback to the user. - The button state update prevents redundant library loads and clearly communicates the app's current state. - Build system upgrades were necessary to make the project compatible with the Java 21 environment (fixing 'Unsupported class file major version 65' and other D8 errors). ♿ Accessibility: - Immediate feedback via Toasts helps users understand the result of their actions. - Clearer button states improve the overall usability of the sample app. Co-authored-by: juankyc <150547187+juankyc@users.noreply.github.com> --- .Jules/palette.md | 3 +++ .../bytedance/shadowhook/sample/MainActivity.java | 14 ++++++++++++++ build.gradle | 6 +++--- gradle.properties | 1 - gradle/wrapper/gradle-wrapper.properties | 2 +- 5 files changed, 21 insertions(+), 5 deletions(-) create mode 100644 .Jules/palette.md diff --git a/.Jules/palette.md b/.Jules/palette.md new file mode 100644 index 0000000..bf70e74 --- /dev/null +++ b/.Jules/palette.md @@ -0,0 +1,3 @@ +## 2026-07-03 - [Android Sample App Feedback Pattern] +**Learning:** For Android apps involving background or native operations (like library loading or hooking), immediate visual feedback via Toasts and button state updates (disabling + text change) significantly improves perceived responsiveness and prevents redundant interactions. +**Action:** Always implement 'click-disable-update' logic for one-way state transitions like library loading, and use Toasts to bridge the gap between UI actions and silent native/background processes. diff --git a/app/src/main/java/com/bytedance/shadowhook/sample/MainActivity.java b/app/src/main/java/com/bytedance/shadowhook/sample/MainActivity.java index 90c3219..7bbc523 100644 --- a/app/src/main/java/com/bytedance/shadowhook/sample/MainActivity.java +++ b/app/src/main/java/com/bytedance/shadowhook/sample/MainActivity.java @@ -29,6 +29,8 @@ import android.os.Bundle;
