Xposed - Can't hook static method

I try to hook Settings.System.putInt method which is static. One of the calls for this method is done in setAirplaneModeOn method of com.android.settings.AirplaneModeEnabler class. It is placed in Settings app of android. Also, putInt method is used in com.android.systemui.

However, following code doesn't hook putInt method. It doesn't give any exception, but it also doesn't dump any log message with content "In android.provider.Settings.System" which means beforeHookedMethod is not called or it couldn't be hooked. Loaded app logs are printed. Any help is greatly appreciated.

@Override
public void handleLoadPackage(final LoadPackageParam lpparam) throws Throwable {
    if (!( lpparam.packageName.equals("com.android.systemui") || lpparam.packageName.equals("com.android.settings"))) {
        return;
    }
    XposedBridge.log("Loaded app: " + lpparam.packageName);
    final Class<?> mClass = XposedHelpers.findClass("android.provider.Settings$System", lpparam.classLoader);
    findAndHookMethod(mClass, "putInt", ContentResolver.class, String.class, "int",  new XC_MethodHook() {
        @Override
        protected void beforeHookedMethod(MethodHookParam param) throws Throwable {
            XposedBridge.log("In android.provider.Settings.System");
        }
    });
}

Xposed-Framework version : 54

Android version: 4.2.2

Since Jelly Bean MR1 (4.2) the method setAirplaneModeOn use putInt in Settings.Global instead Settings.System as you can see here.

Your code should be modified like this:

@Override
public void handleLoadPackage(XC_LoadPackage.LoadPackageParam lpparam) throws Throwable {
    if (!(lpparam.packageName.equals("com.android.systemui") || lpparam.packageName.equals("com.android.settings"))) {
        return;
    }
    XposedBridge.log("Loaded app: " + lpparam.packageName);
    final Class<?> mClass = XposedHelpers.findClass("android.provider.Settings$Global", lpparam.classLoader);
    findAndHookMethod(mClass, "putInt", ContentResolver.class, String.class, int.class, new XC_MethodHook() {
        @Override
        protected void beforeHookedMethod(MethodHookParam param) throws Throwable {
            XposedBridge.log("In android.provider.Settings.Global");
        }
    });
}

I tested the updated code with KitKat 4.4.4 and it works correctly.
