Hi,

Sometimes there is a need to instrument 2 device at the same time. As far as I know , there is no option to choose which device is instrumented. So, it goes random and indtruments one of them only. Could you add support for more device ?

For example, a java function

public byte[] aesEncrypt(String plaintext)

I want to reflect this method,

 var class_name1 = "com.example.cryptutils.util.CryptoUtils";
  var Platform1  = Java.use(class_name1);
var method = Platform1.getDeclaredMethod("aesEncrypt",XXXXX);

how to input the XXXX ?

I think that catch needs a return; statement. When I try to enumerate all classes , it prints lots of undefined because you push null values to the allclasses eventhough it catches an error

classes.forEach(function(aClass) {
	try {
		var className = aClass.match(/[L](.*);/)[1].replace(/\//g, ".");
	}
	catch(err) {} // avoid TypeError: cannot read property 1 of null
	allClasses.push(className);
});

I think needs to be

classes.forEach(function(aClass) {
	try {
		var className = aClass.match(/[L](.*);/)[1].replace(/\//g, ".");
	}
	catch(err) {return;} // avoid TypeError: cannot read property 1 of null
	allClasses.push(className);
});

Title says it all.

I'm trying to trace functions of a specific class of an old old game with broken in-apps.

Having decompiled the game through apktool, I found a class I'm interested.
But no matter how I run the trace function, the game launches, then frida throws an error: Error: java.lang.ClassNotFoundException: Didn't find class "com.game.tka" on path: DexPathList[[zip file "/data/app/~~tnL0853xrVQX1h4toIMrDA==/com.game.tka-aq3_iPPP9AhvI_iyOxSG6g==/base.apk"],nativeLibraryDirectories=[/data/app/~~tnL0853xrVQX1h4toIMrDA==/com.game.tka-aq3_iPPP9AhvI_iyOxSG6g==/lib/arm64, /system/lib64, /system_ext/lib64]]
The main app class is com.game.tka, and I'd like to trace methods of com.game.tka.Dungeons, trace("com.game.tka.Dungeons") doesn't work however.

Am I doing something wrong, or is this script no longer maintained and possibly broken?

https://github.com/frida/frida-java/issues/78，this issue,do you know how to got it ?

See this issue in Frida:
frida/frida#1399

error:

code at /raptor_frida_ios_autoIntercept.js:66

your code:

				// print args
				for (i = 0; i < argCount; i++) {
					printType("\narg " + (i + 1) + " type:\t", args[i + 2]);
					printValue("arg " + (i + 1) + " value:\t", args[i + 2]);
				}

changed code:

				// print args
				for (var i = 0; i < argCount; i++) {
					printType("\narg " + (i + 1) + " type:\t", args[i + 2]);
					printValue("arg " + (i + 1) + " value:\t", args[i + 2]);

Look forward to hearing from you~

Hello, I am using raptor_frida_android_trace.js and I am getting an error upon the app being spawned.

Spawned APP. Resuming main thread! [DEVICE::APP]-> TypeError: cannot read property 1 of null at [anon] (duk_hobject_props.c:2385) at [anon] (repl1.js:46) at frida/node_modules/frida-java/index.js:190 at forEach (native) at d (java.js:2216) at frida/node_modules/frida-java/index.js:120 at trace (repl1.js:51) at [anon] (repl1.js:174) at frida/node_modules/frida-java/lib/vm.js:39 at v (frida/node_modules/frida-java/index.js:338) at frida/node_modules/frida-java/index.js:309 [...]

It looks like the issue is on line 46:
var className = aClass.match(/[L](.*);/)[1].replace(/\//g, ".");

Is there an easy fix like a null check? Could this issue be caused by obfuscation?
