have some problems with static values used as flags.
for example I need to hook 2 methods in different FRAMEWORK classes during initZygote. (no problem with system apps during handleLoadPackage)
I hook method in first class, set static value and waiting when another method of another class will be triggered.
once another method is invoked, flag always has it's initial state.
it looks like each hook method processed in different class instances.
i tried volatile type, tried to synchronize - nothing help.
unreliable remedy:
1. register broadcast receiver inside hook method.
2. send action to own service
3. send broadcast from own service.
4. catch broadcast with receiver.
BUT it is not battery cost efficient solution in my case. And mostly I receive broadcast message when hooking method already processed and returned value. Otherwise I need to wait when service will process request and send broadcast. But it is not usable.
is there any solution?

Code:
public class XMain implements IXposedHookInitPackageResources, IXposedHookZygoteInit, IXposedHookLoadPackage
{
private static boolean isNeedToRun = false;
public void initZygote(StartupParam startupParam) throws Throwable
{
findAndHookMethod("com.class1", null, "method1", int.class, new XC_MethodHook()
{
@Override
protected void beforeHookedMethod(final MethodHookParam param) throws Throwable
{
isNeedToRun = true;
}
});
findAndHookMethod("com.class2", null, "method2", int.class, new XC_MethodHook()
{
@Override
protected void beforeHookedMethod(final MethodHookParam param) throws Throwable
{
if (isNeedToRun) param.setResult(null); // always FALSE even if previous hook set as TRUE
}
});
}
}
