I am on pie so obviously its EdXposed running.
I want to hook a method which is like
Code:
public void setSensorBrightness(int var1) {
Log.d(TAG, "setSensorBrightness: " + var1);
AODCommonSettingsUtils.setBrightnessSettingValue(var1);
this.mSensorBrightness = var1;
}
this original method is located in class "com.samsung.android.app.aodservice.manager.BrightnessManager" and a package name is "com.samsung.android.app.aodservice"
I use reflection as suggested in tutorial otherwise it throws no class found exception.
My code is
Code:
@Override
public void handleLoadPackage(final LoadPackageParam lpparam) throws Throwable
{
if (!lpparam.packageName.equals("com.samsung.android.app.aodservice"))
return;
XposedHelpers.findAndHookMethod(
"com.samsung.android.app.aodservice.manager.BrightnessManager",
lpparam.classLoader,
"setSensorBrightness",
"int",
new MethodHook());
}
protected static class MethodHook extends XC_MethodHook
{
@Override
protected void beforeHookedMethod(MethodHookParam param)
throws Throwable
{
int x =3;
param.args[0]=x;
Log.d("Brightness_hack :", "works");
}
@Override
public boolean equals(Object o)
{
if (o instanceof MethodHook)
{
return true;
}
return super.equals(o);
}
@Override
public int hashCode()
{
return ~MethodHook.class.hashCode() ^ 0xdeadbeef;
}
}
Now my problem is its tooooooo slow hooks in like 15-20 mins and returns no result.
Am I missing something???

Hi, I followed the tutorial on github and tried to hook android.util.Log.i(String tag, String msg) method, but I always get a ClassNotFoundError.
I don't know what I did wrong, my code seems so simple.
Edit: I found the solution. The code below works correctly, the problem was in another part of my code.
Here is the code:
Code:
public void handleLoadPackage(final LoadPackageParam lpparam) throws Throwable
{
XposedBridge.log("Package name: " + lpparam.packageName);
try
{
findAndHookMethod("android.util.Log", lpparam.classLoader, "i", String.class, String.class, new XC_MethodHook()
{
@Override
protected void beforeHookedMethod(MethodHookParam param) throws Throwable
{
//do something before
}
@Override
protected void afterHookedMethod(MethodHookParam param) throws Throwable
{
//do something after
}
});
}
catch (XposedHelpers.ClassNotFoundError e)
{
XposedBridge.log("ClassNotFoundError");
}
catch (NoSuchMethodError e)
{
XposedBridge.log("NoSuchMethodError");
}
}
}
}
I want to hook the constructor with xposed , and the code is as follows ，but there is some wrong.
Code:
XposedHelpers.findAndHookConstructor("java.io.File",
lpparam.classLoader, new XC_MethodHook() {
@Override
protected void beforeHookedMethod(MethodHookParam param)
throws Throwable {
}
@Override
protected void afterHookedMethod(MethodHookParam param)
throws Throwable {
System.out.println("file interception" + "-------------->"
+ param.args[0]);
}
});
Error content:
java.lang.NoSuchMethodError: java.io.File()#exact
Thanks
That's because there is no File() constructor. To hook e.g. File(String filename), you need to use:
Code:
XposedHelpers.findAndHookConstructor("java.io.File",
lpparam.classLoader, [COLOR="Red"][B]String.class, [/B][/COLOR]new XC_MethodHook() {
or simply
Code:
XposedHelpers.findAndHookConstructor(File.class, [COLOR="Red"][B]String.class, [/B][/COLOR]new XC_MethodHook() {
Be careful with such generic classes though, you can easily get lots of calls to it.

It works, thanks you very much .
I want to modify some static field in android.os.Build, such as android.os.Build.BOARD, android.os.Build.DEVICE, android.os.Build.DISPLAY.
Then I tried to hook the static method 'getString(String s)' in android.os.Build .
Code:
public void handleLoadPackage(final XC_LoadPackage.LoadPackageParam loadPackageParam) throws Throwable {
XposedBridge.log(loadPackageParam.packageName + " -> load ");
Class build = XposedHelpers.findClass(Build.class.getName(), loadPackageParam.classLoader);
XposedHelpers.findAndHookMethod(build, "getString", String.class, new XC_MethodHook() {
@Override
protected void beforeHookedMethod(MethodHookParam param) throws Throwable {
XposedBridge.log("before ->" + param.args[0]);
super.beforeHookedMethod(param);
}
@Override
protected void afterHookedMethod(MethodHookParam param) throws Throwable {
XposedBridge.log("after ->" + param.args[0]);
super.afterHookedMethod(param);
}
});
I wrote
Code:
txvTxt = (TextView) findViewById(R.id.txvTxt);
txvTxt.setText(Build.DISPLAY);
in my activity, I could not see any before or after hook message.
Waiting online for any solution. 3Q
Code:
public class SuperHook implements IXposedHookLoadPackage, IXposedHookZygoteInit {
Config mConfig;
Gson mGson;
@Override
public void initZygote(StartupParam startupParam) throws Throwable {
mConfig = new Config();
mGson = new Gson();
}
@Override
public void handleLoadPackage(XC_LoadPackage.LoadPackageParam loadPackageParam) throws Throwable {
Log.d("SuperHook", "handleLoadPackage imei:" + mConfig.getmImei());
if (loadPackageParam.packageName.equals("cn.superscript.supertools")) {
Class<?> classSuperService = XposedHelpers.findClass(SuperService.class.getName(), loadPackageParam.classLoader);
XposedHelpers.findAndHookMethod(classSuperService, "onStartCommand", Intent.class, int.class, int.class, new XC_MethodHook() {
@Override
protected void afterHookedMethod(MethodHookParam param) throws Throwable {
super.afterHookedMethod(param);
Intent intent = (Intent) param.args[0];
String json = intent.getStringExtra("json");
mConfig = mGson.fromJson(json, new TypeToken<Config>() {
}.getType());
Log.d("SuperHook", "onStartCommand: imei = " + mConfig.getmImei());
}
});
}
}
}
Log:
01-21 18:49:56.220 664-664/? D/SuperHook: handleLoadPackage imei:null
01-21 18:49:56.240 664-664/? D/SuperHook: onStartCommand: imei = 3333333
01-21 18:50:00.930 757-757/com.android.settings D/SuperHook: handleLoadPackage imei:null
why handleLoadPackage imei = null , onStartCommand: imei = 3333333 successful.
Please help me, thank you
The code:
Code:
updateNotifications([Lcom/samsung/android/uniform/widget/notification/NotificationItem;)V
As you can see, I need an array of "NotificationItem"
But when I do this:
Code:
XposedHelpers.findAndHookMethod(NotiContainer, "updateNotifications", NotiItem[].class, new XC_MethodHook() {
@Override
protected void beforeHookedMethod(MethodHookParam param) throws Throwable {
}
});
I get "unknown class NotiItem"
so yeah.. kinda confused.
I tried this too:
Code:
XposedHelpers.findAndHookMethod(NotiContainer, "updateNotifications", "[com.samsung.android.uniform.widget.notification.NotificationItem", new XC_MethodHook() {
@Override
protected void beforeHookedMethod(MethodHookParam param) throws Throwable {
}
});
But I get "ClassNotFound Exception: Invalid Name"
How the heck can I do this...
Solved using "com.samsung.android.uniform.widget.notification.NotificationItem[]" instead of "[com.samsung.android.uniform.widget.notification.NotificationItem" as the class name.
