Question

我正在通过改造提出异步请求，在请求中间我最小化应用并使应用崩溃......

我的日志错误：

java.lang.IllegalStateException: Can not perform this action after onSaveInstanceState
at android.support.v4.app.FragmentManagerImpl.checkStateLoss(FragmentManager.java:1842)

如果请求返回成功，它就是我调用的方法：

ActivityUtils.replaceFragmentToActivityWithBackStack(getFragmentManager(), IncompleteStatusFragment.newInstance(mLogin.getCustomerId(), mCustomer, prospect, mLogin), R.id.container_login);

有人可以帮助我吗？

很明显，如果你最小化应用程序，那么你将无法替换该片段，因为你的应用程序不在焦点上。抛出java.lang.IllegalStateException。你应该保持一面旗帜和在你的活动的onResume中，如果该标志为真，则替换该片段。

像

@Override
public void onPause() {
   mIsActivityVisible = false;
}

@Override
public void onResume() {
   mIsActivityVisible = true;
   if(mShouldReplaceFragmentOnResume) {
      mShouldReplaceFragmentOnResume = false;
      // replace fragment
   }
}

// On Success response
onSuccessOfYourCall() {
   if(mIsActivityVisible) {
       //replace fragment
   } else {
       mShouldReplaceFragmentOnResume = true;
   }
}

最小化App Produces在onSaveInstanceState之后无法执行此操作
