I'm a beginner with Frida. When I first started using Frida, I encountered an error.

Android version: 11 frida-server version: 17.0.7

└─$ pip list | grep frida
frida                          17.0.7
frida-tools                    14.0.2

The js files used are as follows:

console.log("frida agent started");
try {
  console.log("Process.arch = " + Process.arch);
} catch (e) {
  console.log("Process.arch unknown: " + e);
}
console.log("typeof Java = " + typeof Java);

setImmediate(function () {
  try {
    if (typeof Java !== "undefined" && Java.available) {
      console.log("Java.available = true");
      Java.perform(function () {
        try {
          console.log(
            "Java.perform OK. Runtime: " + Java.vm.getEnv().getClass()
          );
        } catch (e) {
          console.log("Java.perform inner error: " + e);
        }
      });
    } else {
      console.log(
        "Java.available = false (no Java VM exposed to this process)"
      );
    }
  } catch (e) {
    console.log("probe setImmediate error: " + e);
  }
});

Regarding the version correspondence aspect, I have made the corresponding arrangements according to the following GitHub repository.

How should I solve this error?

  • Your Android version is pretty old. It often happens that newer Frida versions do not work well with older Android versions because of patches for newer Android versions. I would try an older Frida version. Note that with Frida 17.0 some breaking changes were introduced. Therefore for using older Frida versions it might be require to make some minor changes to your code. Commented Nov 10 at 8:06
  • @Robert I once tried version 14.2.18, but this error still occurred. I don't know how to match it with the Android version. Is there a table for the correspondence? Commented Nov 11 at 2:50
  • Is there a special need why you use code in setImmediate instead of directly writing it into the script? Commented Nov 11 at 8:48
  • @Robert There was no specific reason. The above code was merely something I copied and pasted to verify since I suspected that the error was due to a problem with my code. Additionally, the purpose of using Frida was simply to view the callback code triggered when a button is pressed. Commented Nov 11 at 11:05
