I make a xposed module to modify the google messenger application but I have a problem with a class that xposed can't find using the boot class loader :
public class XposedModSendTimestamp implements IXposedHookLoadPackage {
public void handleLoadPackage(final LoadPackageParam lpparam) throws Throwable {
if (!lpparam.packageName.equals("com.google.android.apps.messaging"))
return;
XposedBridge.log("Attempt to hook ConversationMessageView.a");
findAndHookMethod("com.google.android.apps.messaging.ui.ConversationMessageView", lpparam.classLoader, "a", Cursor.class, String.class, "boolean", String.class, new XC_MethodHook() {
@Override
protected void beforeHookedMethod(MethodHookParam param) throws Throwable{
//code
}
});
}
}
Errors from xposed log :

I tried this configuration with the tutorial example from here and it worked so I think it's about the application and possibly about the class loader but I don't know much about this.
So please help me, I don't understand.
