[SOLVED] java.lang.NoSuchMethodError where such a method exists

Hello, I get the following exception in logcat
Code:
E/Xposed (10014): java.lang.NoSuchMethodError: com.android.keyguard.KeyguardSecurityContainer#updateSecurityView(android.view.View,java.lang.Boolean)#exact
and my code is
Code:
public class XposedMod implements IXposedHookLoadPackage {
@Override
public void handleLoadPackage(LoadPackageParam lpparam) throws Throwable {
if ((Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) && (lpparam.packageName.contains("android.keyguard") || lpparam.packageName.contains("com.android.systemui")))
{
Class<?> KeyguardHostView = XposedHelpers.findClass("com.android.keyguard.KeyguardSecurityContainer", lpparam.classLoader);
findAndHookMethod(KeyguardHostView, "updateSecurityView", View.class, Boolean.class, mUpdateSecurityViewHook);
}
}
The method exists here https://github.com/android/platform.../keyguard/KeyguardSecurityContainer.java#L139
What should I do? Thanks for your help!

Code:
findAndHookMethod(KeyguardHostView, "updateSecurityView", View.class, boolean.class, mUpdateSecurityViewHook);
The primitive boolean was to be used instead of the boxed Boolean

Make class and paste this content
PHP:
import java.lang.reflect.Method;
import de.robv.android.xposed.XC_MethodHook;
import de.robv.android.xposed.XposedBridge;
import de.robv.android.xposed.XposedHelpers;
public class XposedWrapper {
public static XC_MethodHook.Unhook hookMethod(Class<?> sClass,String method_Name,Object... parameterTypesAndCallback) {
Method method = XposedHelpers.findMethodBestMatch(sClass,method_Name,removeCallback(parameterTypesAndCallback));
XC_MethodHook callback = (XC_MethodHook) parameterTypesAndCallback[parameterTypesAndCallback.length-1];
return XposedBridge.hookMethod(method,callback);
}
private static Object[] removeCallback(Object... args) {
Object[] list = new Object[args.length-1];
for (int i = 0 ; i < args.length ; i++) {
if (!(args[i] instanceof XC_MethodHook)) {
list[i] = args[i];
}
}
return list;
}
}
Now in the xposed class
do like this
PHP:
XposedWrapper.hookMethod(KeyguardHostView, "updateSecurityView", View.class, Boolean.class, new XC_MethodHook() {
@Override
protected void afterHookedMethod(MethodHookParam param) throws Throwable {
XposedBridge.log("Hooked");
}
});

FindViewById from hooked method?

Hello!
I'm trying to make Xposed module from this patch: https://github.com/CyanogenMod/android_frameworks_base/commit/19e458f4a26fe7c8b6419cadba81a0c46dc79dad
My code looks like this:
Code:
@Override
public void initZygote(StartupParam startupParam) throws Throwable {
MODULE_PATH = startupParam.modulePath;
}
@Override
public void handleInitPackageResources(XC_InitPackageResources.InitPackageResourcesParam resparam) throws Throwable {
if (!resparam.packageName.equals(PACKAGE_NAME))
return;
XModuleResources modRes = XModuleResources.createInstance(MODULE_PATH, resparam.res);
mFakeIdScrimview = resparam.res.addResource(modRes, R.id.scrimview);
mFakeIdVisView = resparam.res.addResource(modRes, R.id.visualizerview);
}
public void handleLoadPackage(final LoadPackageParam lpparam) throws Throwable {
if (!lpparam.packageName.equals(PACKAGE_NAME))
return;
findAndHookMethod("com.android.systemui.statusbar.phone.PhoneStatusBar", lpparam.classLoader,
"makeStatusBarView", new XC_MethodHook() {
@Override
protected void afterHookedMethod(MethodHookParam param) throws Throwable {
FrameLayout lStatusBarWindow = (FrameLayout) XposedHelpers.getObjectField(param.thisObject, "mStatusBarWindow");
FrameLayout scrimView = (FrameLayout) lStatusBarWindow.findViewById(mFakeIdScrimview);
if (scrimView != null) {
mVisualizerView = (VisualizerView) scrimView.findViewById(mFakeIdVisView);
} else {
XposedBridge.log("scrimView = null !!!!");
}
if (mVisualizerView != null){
mVisualizerView.setKeyguardMonitor(mKeyguardMonitor);
} else {
XposedBridge.log("mVisualizerView = null !!!!! ");
}
}
});
The problem is that scrimView is always null and I can't get this piece of code working.
Anybody has any idea?

Untested, but could you try to replace your scrimView assignment line with this
Code:
FrameLayout scrimView = (FrameLayout) XposedHelpers.callMethod(lStatusBarWindow, "findViewById", mFakeIdScrimview);

Unfortunately scrimView is still null.

Hook long press notification

How can you guys capture long press notification?
I found this method on SystemUI:
Code:
Code:
protected SwipeHelper.LongPressListener getNotificatioLongnClicker() {
return new SwipeHelper.LongPressListener() {
[user=439709]@override[/user]
public boolean onLongPress(View v, int x, int y) {...
But I can't do afterHookedMethod or beforeHookedMethod.
Code:
Code:
public class Tutorial implements IXposedHookLoadPackage {
public void handleLoadPackage(final LoadPackageParam lpparam) throws Throwable {
XposedBridge.log("Loaded app: " + lpparam.packageName);
if (!lpparam.packageName.equals("com.android.systemui"))
return;
findAndHookMethod("com.android.systemui.statusbar.BaseStatusBar", lpparam.classLoader, "getNotificationLongClicker", new XC_MethodHook() {
[user=439709]@override[/user]
protected void afterHookedMethod (MethodHookParam param) throws Throwable {
// this will be called before the clock was updated by the original method
return new View.OnLongClickListener() {
[user=439709]@override[/user]
public boolean onLongClick(final View v) {
XposedBridge.log("long press notification action");
return true;
}
}
});
}
}
}
How I can call the method from another class "SwipeHelper" and access "LongPressListener" public interface and "onLongPress" method which return boolean value?
I tried with object and method "View.OnLongClickListener" without success. Anyway, if I can't do it there is another way because I see system long press notification working on xNotification module.

Hi, View.OnLongClickListener is not a method, it's an interface. Basically what you need to do is get the method result in your hook (it would be either SwipeHelper or OnClickListener based on your Andorid version) and use it based on its methods and your needs

Boolean Replacement

Hey Guys..
I have a problem with my xposed module.
I will a class to boolean false not true if rooted device..
Code:
public static boolean isRooted()
This to return false if rooted device..
Code:
XposedHelpers.findAndHockMethod("com.example.utils.RootCheck", lpparam.classLoader, "isRooted", boolean.class, new XC_MethodHook() {
@Override
protected void beforeHookedMethod(MethodHookParam param) throws Throwable {
param.args[0] = false;
}
});
Xposed say me nosuchmethoderror com.example.utils.RootCheck#isRooted(boolean)..
Can help me..
Thanks
Sorry for my bad English i m a german.

what class is it, is it your own?
are you filtering by package name?

Is not my own class..
From another Application..

This is the class. i have decoded.
I want replace "public static final String" , public static boolean isRooted() to ever false and private static boolean a(String str) to ever false..
can help me?

public static final String VALUE_DEVICE_FLAG_SU = "su";
public static final String VALUE_DEVICE_FLAG_SUPER_USER_APK = "superuser.apk";
public static final String VALUE_DEVICE_FLAG_TEST_KEYS = "testkeys";

oh wait, isRooted doesn't take any arguments and you're trying to hook isRooted with a boolean argument, which would be a different method
return values are called result here (getResult, setResult.) args is only for arguments

Oh thx

Code:
06-17 22:21:05.373: E/Xposed(30470): java.lang.NullPointerException: Attempt to invoke virtual method 'boolean java.lang.Boolean.booleanValue()' on a null object reference
06-17 22:21:05.373: E/Xposed(30470): at de.bozja.hrh.Hidder$1.beforeHookedMethod(Hidder.java:22)
Error why?
class
Code:
findAndHookMethod("com.example.RootCheck", lpparam.classLoader, "isRooted", new XC_MethodHook() {
@Override
protected void beforeHookedMethod(MethodHookParam param) throws Throwable {
boolean isRoot = (Boolean) param.getResult(); //Error on this line
if(isRoot == true)
isRoot = false;
param.setResult(isRoot);
}
@Override
protected void afterHookedMethod(MethodHookParam param) throws Throwable {
boolean isRoot = (Boolean) param.getResult();
if(isRoot == true)
isRoot = false;
param.setResult(isRoot);
}
});

beforeHookedMethod is called before the method is executed, so there can't be any result. so it's null

Just setresult to false in beforehooked dont add extra junk
And dont hook method afterhook no need before will do what u need

i am also facing the same issue today when trying to hook some certain method that doesnt take in any argument. And i really didnt get the answer you gave. Could you be more elaborate please?

that was a long time. necrobumping from Google?
I think I meant to use param.setResult instead of param.args[0] to set the return value

this is the method i want to hook. I want it to return false
public boolean vpn() {

return false;
}
NetworkInterface networkInterface = (NetworkInterface) it.next();
if (networkInterface.isUp()) {
str = networkInterface.getName();
}
StringBuilder stringBuilder = new StringBuilder();
stringBuilder.append("IFACE NAME: ");
stringBuilder.append(str);
Log.d("DEBUG", stringBuilder.toString());
if (str.contains("tun") || str.contains("ppp")) {
Toast.makeText(getContext(), "Hello vpn detected", 1).show();
}
} while (!str.contains("pptp"));
Toast.makeText(getContext(), "Hello vpn detected", 1).show();
return true;
} catch (SocketException e) {
e.printStackTrace();

and this is my kotlin class

}

am i doing it wrong? it still doesnt work. The class and method locations are correct

this should be a separate thread imo
XC_MethodHook | Xposed Framework API
api.xposed.info
in Java there would be no need for the super call and the syntax is .setResult, but I'm not sure in Kotlin

about the .setResult(false) the compiler suggests .result = false

Can't change navigation bar buttons icons with my Xposed module

Hello friends!
I"m trying to build xposed module for educational purposes.
I want the module to:
1. Change the navigation bar color to green - this one works OK.
2. Change the navigation bar icons to custom icons i provide from my drawable resources - this one partially works, as described below.
The "home" button is changed, but the "recent apps" and "back" buttons didn't. Please see picture attached.
Can some one tell me why i can change the "home" button but not the "recent apps" and "back" buttons?
Any suggestion how to fix this?
module code:
Code:
import android.content.Context;
import android.content.res.XModuleResources;
import de.robv.android.xposed.IXposedHookInitPackageResources;
import de.robv.android.xposed.IXposedHookZygoteInit;
import de.robv.android.xposed.XposedBridge;
import de.robv.android.xposed.callbacks.XC_InitPackageResources.InitPackageResourcesParam;
import de.robv.android.xposed.callbacks.XC_LayoutInflated;
import android.graphics.Color;
import android.view.View;
import android.widget.ImageView;
import android.widget.LinearLayout;
public class TweakNavigationBar implements IXposedHookZygoteInit, IXposedHookInitPackageResources {
private static String MODULE_PATH = null;
@Override
public void initZygote(StartupParam startupParam) throws Throwable {
MODULE_PATH = startupParam.modulePath;
}
@Override
public void handleInitPackageResources(InitPackageResourcesParam resparam) throws Throwable {
if (!resparam.packageName.equals("com.android.systemui"))
return;
resparam.res.hookLayout("com.android.systemui", "layout", "navigation_bar", new XC_LayoutInflated() {
@Override
public void handleLayoutInflated(LayoutInflatedParam liparam) throws Throwable {
XModuleResources modRes = XModuleResources.createInstance(MODULE_PATH, liparam.res);
LinearLayout NavigationButtonsLayout = (LinearLayout) liparam.view.findViewById(
liparam.res.getIdentifier("nav_buttons", "id", "com.android.systemui"));
NavigationButtonsLayout.setBackgroundColor(Color.GREEN);
Context mContext = NavigationButtonsLayout.getContext();
ImageView backButton = (ImageView) liparam.view.findViewById(liparam.res.getIdentifier("back", "id", "com.android.systemui"));
ImageView homeButton = (ImageView) liparam.view.findViewById(liparam.res.getIdentifier("home", "id", "com.android.systemui"));
ImageView recentButton = (ImageView) liparam.view.findViewById(liparam.res.getIdentifier("recent_apps", "id", "com.android.systemui"));
//this also didn't work
//ImageView backButton = (ImageView) NavigationButtonsLayout.getChildAt(2);
//ImageView homeButton = (ImageView) NavigationButtonsLayout.getChildAt(3);
//ImageView recentButton = (ImageView) NavigationButtonsLayout.getChildAt(4);
recentButton.setImageDrawable(modRes.getDrawable(R.drawable.blue_button,null)); // didn't work!
homeButton.setImageDrawable(modRes.getDrawable(R.drawable.red_button,null)); // WORKS!
backButton.setImageDrawable(modRes.getDrawable(R.drawable,yellow_button,null)); // didn't work!
XposedBridge.log("start scan:");
for(int i=0; i< NavigationButtonsLayout.getChildCount() ; i++) {
View viewChild = (View) NavigationButtonsLayout.getChildAt(i);
XposedBridge.log(viewChild.toString());
if(viewChild instanceof ImageView)
XposedBridge.log("Child At " + i + " is instanceof ImageView" ) ;
}
}
});
}
}

Use this:
resparam.res.setReplacement(SYSTEM_UI, "drawable", "ic_sysbar_back_ime", modRes.fwd(R.drawable.n_back_down));
resparam.res.setReplacement(SYSTEM_UI, "drawable", "ic_sysbar_recent", modRes.fwd(R.drawable.n_recents));
resparam.res.setReplacement(SYSTEM_UI, "drawable", "ic_sysbar_back", modRes.fwd(R.drawable.n_back));
Note: SYSTEM_UI="com.android.systemui"
Using my method, i wasnt able to change the home button. But using your method, it did!
Thanks man!
