Android ANR-输入调度超时

Question

我已经开始从许多代码位置收到几个奇怪的ANR报告（应用程序没有响应）。

at android.support.v7.app.AppCompatActivity.setContentView (AppCompatActivity.java:139)
at br.com.xxx.xxx.activities.MainActivity.onCreate (MainActivity.java:71)
at android.app.Activity.performCreate (Activity.java:6245)

MainActivity.java:71: setContentView(R.layout.activity_main);

at android.support.v4.app.BackStackRecord.replace (BackStackRecord.java:421)
at br.com.xxx.xxx.activities.MainActivity.openFragment (MainActivity.java:146)
at br.com.xxx.xxx.activities.MainActivity.openMenu (MainActivity.java:121)

                       currentFragment = new CardsFragment();
MainActivity.java:146: openFragment(currentFragment);

您的问题发生在Handler中，这意味着它发生在主线程上。您应该调用一个IO线程上的所有计费处理器方法，以避免阻塞您的主线程。

有太多可能的方法可以做到这一点，以简洁的描述。AsyncTasks、RxJava、vanilla线程、Android服务等。
