Issue-JniOnLoad

For reporting issue https://issuetracker.google.com/issues/220523932.

Guide

The core source files are following:

  1. foo.cc, the code of library foo, with NO JNI_OnLoad defined.
  2. bar.cc, the code of library bar, with JNI_OnLoad defined.
  3. CMakeLists.txt, defines libraries foo, bar and their relationship.
  4. MainActivity, load libraries foo and bar.

Steps to reproduce issue

  1. Run the code
  2. Click text "CLICK ME TO EXECUTE"
  3. You will see the logcat output:
2022-02-21 15:38:27.116 12825-12825/com.example.foo D/Bar: JNI_OnLoad: count = 1
2022-02-21 15:38:27.117 12825-12825/com.example.foo D/Bar: JNI_OnLoad: count = 2
2022-02-21 15:38:27.117 12825-12825/com.example.foo D/Foo: call function of library bar: 3

which means the JNI_OnLoad of libbar.so was called twice.
