Question

我在使用API24和API25（Android Nougat）的Android设备上创建Runnable（）时遇到了一些问题。总之，我正在尝试做类似的事情：

MyAsyncTask myTask = new MyAsyncTask();
myTask.executeTask(new AsyncTaskListener() {
@Override
public void onTaskFinished(Object result) {
    try {
        Runnable r = new Runnable() {
            @Override
            public void run() {
                Log.i("Test", "Hello Runnable");
            }
        };
    }
    catch (Exception ex) {
        Log.i("Test", "Exception");
    }
}
});

在早于24的API上，一切正常，但在API24和25上，我正在捕捉异常：

Attempt to invoke virtual method 'boolean java.lang.Class.isAnonymousClass()' on a null object reference

任何想法，提示或建议如何解决这个问题？

行：

指向我创建Runnable实例时的行。我没有事件执行创建Runnable。在上面的代码中，我尽可能多地删除了哪一行导致崩溃问题。

在Android Nougat上调用新的Runnable（）崩溃
