Xposed hook SensorManager

Xposed hook SensorManager

本篇继续新增hook sensorManager. 用于替换运动量的数值。

public class SportHook {
    private static final String TAG = "SportHook";
    private static int stepCount = 1;

    public static void hook(XC_LoadPackage.LoadPackageParam lpparam) {
        if (!lpparam.packageName.equals("com.tencent.mm")) return;
        Log.i(TAG, "hook: start");
        try {
            final Class clazz = XposedHelpers.findClass("android.hardware.SystemSensorManager$SensorEventQueue", lpparam.classLoader);
            XposedBridge.hookAllMethods(clazz, "dispatchSensorEvent", new XC_MethodHook() {
                @Override
                protected void beforeHookedMethod(MethodHookParam param) throws Throwable {
//                    ((float[]) param.args[1])[0] = ((float[]) param.args[1])[0] + 1123 * stepCount;
                    ((float[]) param.args[1])[0] = 1123 * stepCount;
                    stepCount++;
                }

                @Override
                protected void afterHookedMethod(MethodHookParam param) throws Throwable {
                    super.afterHookedMethod(param);
                }
            });
        } catch (Throwable e) {
            Log.e(TAG, "hook: ", e);
        }
        Log.i(TAG, "hook: end");
    }
}

如上，直接修改dispatchSensorEvent 方法中参数的值。

这里不考虑加速度传感器的问题。

public class HookModule implements IXposedHookLoadPackage {

    public static final String TAG = "HookModule";

    @Override
    public void handleLoadPackage(XC_LoadPackage.LoadPackageParam lpparam) throws Throwable {
        Log.e(TAG, "handleLoadPackage");
        SportHook.hook(lpparam);
    }

}
