Xposed Not Loading my module, ClassNotFoundException

Question

I am developing an Xposed module, as an expansion of FatMinMin's minminHide module also it seems like a good dev exercise as well :) The issue is that during boot when I check the xposed log i get the below:

5-04 17:06:44.305 I/Xposed  (581): Loading modules from /data/app/xposed.sudocode.com.sudohide-1/base.apk

which means that Xposed was not able to load my module properly

In the xposed_init file I have the following:

xposed.sudocode.com.sudohide.XposedMain

I also added the xposed bridge api in the dependency:

dependencies {
    provided files('libs/api-82.jar')
    compile 'com.android.support:appcompat-v7:23.3.0'
}

This is The beginning of my Class java file:

package xposed.sudocode.com.sudohide;


import android.content.pm.ApplicationInfo;
import android.content.pm.PackageInfo;
import android.content.pm.ResolveInfo;
import android.os.Binder;

import java.util.ArrayList;
import java.util.List;

import de.robv.android.xposed.IXposedHookLoadPackage;
import de.robv.android.xposed.IXposedHookZygoteInit;
import de.robv.android.xposed.XC_MethodHook;
import de.robv.android.xposed.XSharedPreferences;
import de.robv.android.xposed.XposedBridge;
import de.robv.android.xposed.XposedHelpers;
import de.robv.android.xposed.callbacks.XC_LoadPackage;

public class XposedMain implements IXposedHookZygoteInit, IXposedHookLoadPackage {

Can anyone please provide any form of advice on how to proceed, I attempted to search for a solution but I could not find any, nor did I find anything in the xposed documentation

Thanks!

Answer 1

Solved the Issue! The issue was with the instant run on android studio, it was installing the app in /data/local/tmp/ and xposed was not finding the class in that path.

Now I push the apk to the device and install from storage

Answer 2

Try put xposed api jar outside libs dir (root of your project, for example) and fix gradle config file.

Answer 3

Just disable Instant Run

File -> Settings -> Build, Execution, Deployment -> Instant Run

Otherwise your classes aren't included directly in the APK, but loaded via a stub application which Xposed can't handle.

Answer 4

In my case, I forgot to add the assets folder that contained: xposed_init (has no extension)

that also contained: the.package.name.XposedClassWhereYouHookedStuff

for example: com.example.sampleapp.xposedclass

in the directory: AppName/app/src/main/assets

and i also Disable Instant Run
