Android Fatal Error - Kann diese Aktion nach onSaveInstanceState nicht ausführen

Question

Ich versuche, eine Fragmenttransaktion nach dem Anfordern von Berechtigungen in Android durchzuführen - jedoch stürzt die App ständig ab. Wie kann dieser Code geändert werden, um dies zu vermeiden?

Jede Hilfe wird geschätzt.

Check PERMISSIONS VOR DER EINREICHUNG E-MAIL:

private void emailShare() { 
    if (mayRequestContacts()) { 
     emailShareImpl(); 
    } 
} 

Check PERMISSIONS:

private boolean mayRequestContacts() { 
     if (Build.VERSION.SDK_INT < Build.VERSION_CODES.M) { 
      return true; 
     } 

     requestPermissions(new String[]{READ_CONTACTS}, REQUEST_READ_CONTACTS); 

     return false; 
    } 

PERMISSION TEST ERGEBNIS:

@Override 
    public void onRequestPermissionsResult(int requestCode, String[] permissions, int[] grantResults) { 
     if (requestCode == REQUEST_READ_CONTACTS) { 
      if (grantResults.length == 1 && grantResults[0] == PackageManager.PERMISSION_GRANTED) { 
       emailShareImpl(); 
      } 
     } 
    } 

INITIIEREN FRAGMENT Transaktion, wenn die Erlaubnis erteilt:

private void emailShareImpl() { 
     FragmentManager fragmentManager = getActivity().getSupportFragmentManager(); 
     EmailReferDialog mEmailReferDialog = new EmailReferDialog(); 
     mEmailReferDialog.setCancelable(true); 
     mEmailReferDialog.show(fragmentManager, "EMAIL_REFER_DIALOG"); 
    }

Answer 1

Dies geschieht, weil onRequestPermissionresult vor Aktivität des onResume genannt wird. Sie können einfach dieses Problem beheben, indem Sie:

private boolean mShareEmail = false; 

@Override 
public void onRequestPermissionsResult(int requestCode, String[] permissions, int[] grantResults) { 
    if (requestCode == REQUEST_READ_CONTACTS) { 
     if (grantResults.length == 1 && grantResults[0] == PackageManager.PERMISSION_GRANTED) { 
      mShareEmail = true; 
     } 
    } 
} 

@Override 
public void onResume() { 
    super.onResume(); 
    if (mShareEmail) { 
     emailShareImpl(); 
     mShareEmail = false; 
    } 
} 

Answer 2

Vielleicht ist die folgende Spitze ist ein bisschen spät, aber anstatt das Problem zu umgehen, wenn Sie nicht über die staatliche Aktivität verwenden (zum Beispiel sollte das Berechtigungsmodell staatenlos sein) sollten Sie während des Fragmentübergangs commitAllowingStateLoss verwenden.

Answer 3

ich diese Proble gelöst durch einen Handler hinzufügen:

new Handler().postDelayed(new Runnable() { 
      @Override 
      public void run() { 
       new FolderChooserDialog.Builder(ReportActivity.this) 
         .tag(REQUEST_CODE_Excel+"") 
         .show(); 
      } 
     }, 500);
