[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.

[Need Help] [Hooking init method]

Hi, I have StatusBarIconView.smali (com/android/systemui/statusbar) and I want to hook this method:
Code:
.method public constructor <init>(Landroid/content/Context;Ljava/lang/String;Landroid/app/Notification;)V
.locals 5
.param p1, "context" # Landroid/content/Context;
.param p2, "slot" # Ljava/lang/String;
.param p3, "notification" # Landroid/app/Notification;
...........................Here we have some code.......................
.line 84
.local v0, "iconPadding":I
invoke-virtual {p0, v0, v4, v0, v4}, Lcom/android/systemui/statusbar/StatusBarIconView;->setPadding(IIII)V
.line 85
return-void
.end method
I want to hook this method in order to change padding.
Using BatchApktool I can see java code:
PHP:
public StatusBarIconView(Context context, String slot, Notification notification) {
super(context);
Resources res = context.getResources();
this.mSlot = slot;
this.mNumberPain = new Paint();
this.mNumberPain.setTextAlign(Align.CENTER);
this.mNumberPain.setColor(res.getColor(R.drawable.notification_number_text_color));
this.mNumberPain.setAntiAlias(true);
this.mNotification = notification;
setContentDescription(notification);
int iconPadding = getResources().getDimensionPixelSize(R.dimen.status_bar_icon_padding);
setPadding(iconPadding, 0, iconPadding, 0);
}
I can change padding manually with .smali editing. But I want to change it with xposed module.
And I don't know how to hook this <init> method properly. Is it possible at all?
Here's what I tried:
PHP:
XposedHelpers.findAndHookMethod("com.android.systemui.statusbar.StatusBarIconView", lpparam.classLoader, "init",Context.class,String.class, "android.app.Notification" ,new XC_MethodHook() {
@Override protected void afterHookedMethod(final MethodHookParam param) throws Throwable {
View v = (View) param.thisObject;
v.setPadding(3, 15, 3, 15);
}
});
And I got noclassfound error (or nosuchmethod error ... forgot which one)
Also I replaced "init" with "<init>" or "StatusBarIconView" with no result as well.

<init> is basically a constructor.
Use XposedHelpers.findAndHookConstructor instead of findAndHookMethod.

Getting LongPress on Back/Volume Keys (Hooked, But Cant't Get LongPress)

Hello, I've hooked a method to get KeysEvent, but I've ran into 2 problems :
1. Can't get long press.
2. Getting up to 7 events when it's only 1 event, Explain ? I've added a log.i in "if(blabla == VOLUME_DOWN ), When i press that key i get the log 7 times.
Here's the code :
HTML:
public static void init() {
final Class localClass = XposedHelpers.findClass("com.android.internal.policy.impl.PhoneWindowManager", Xposed.CLASS_LOADER);
XposedBridge.hookAllConstructors(localClass, new XC_MethodHook() {
protected void afterHookedMethod(final XC_MethodHook.MethodHookParam paramAnonymousMethodHookParam)
throws Throwable {
}
});
XposedHelpers.findAndHookMethod(localClass, "interceptKeyBeforeQueueing", KeyEvent.class, Integer.TYPE, new XC_MethodHook() {
[user=439709]@override[/user]
protected void beforeHookedMethod(MethodHookParam param)
throws Throwable {
KeyEvent event = (KeyEvent) param.args[0];
int code = event.getKeyCode();
if (code == KeyEvent.KEYCODE_BACK) {
Log.i(Xposed.TAG, "Back Pressed");
}
}
});

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
