jnitrace is a Frida-based command-line tool that dynamically traces JNI API calls made by native libraries in Android apps. It works like frida-trace or strace but specifically for the JNI, helping reverse engineers follow interactions between native code and the Android Runtime.

Use cases

• trace JNI calls in an Android app's native library
• dynamically analyze how native code uses the Android Runtime
• reverse engineer obfuscated native libraries on Android
• monitor RegisterNatives and other JNI method usage
• reduce noise when tracing large JNI-heavy apps with include/exclude filters
• capture backtraces of JNI calls during app execution

When to choose

• you need to understand what JNI API calls an Android app's native libraries make
• you already use Frida and want a strace-like tool for JNI
• manual static reverse engineering of native code is too slow

When to avoid

• you need static analysis of native binaries without running them
• your target device cannot run a Frida server
• you are analyzing non-Android native code
