Simplify

Isn't this easier?)

@Override
public void initZygote(StartupParam startupParam) throws Throwable {
    XposedHelpers.findAndHookMethod("android.app.ContextImpl", null, "enforceCallingPermission", String.class, String.class, new XC_MethodHook() {
        @Override
        protected void beforeHookedMethod(MethodHookParam param) throws Throwable {
            if (param.args[0].equals("android.permission.BATTERY_STATS")) param.setResult(null);
        }
    });
}

You should also hook Android methods on initZygote with null classloader, not on every package load. Strange that it doesn't currently throw tons of exceptions :)
