Wie öffne ich .xlsx Dateien in Android?

Question

Ich schrieb App vor ein paar Monaten. Ich hatte Note 2 mit Android Kitkat (und es war in Ordnung). Meine Freunde haben getestet (und jetzt benutzen sie es) und alles ist in Ordnung.

Ich kaufte neues Telefon mit Android Nougat (7.0). Jetzt kann ich .xlsx Datei nicht öffnen. Ich verwende diese Methode, wenn ich auf die Schaltfläche klicke.

private void ReadXLSX() { 
    nameFILE= "OOOO.xlsx"; 
    Intent target = new Intent(Intent.ACTION_VIEW); 
    target.setDataAndType(Uri.fromFile(new File((getExternalFilesDir(Environment.DIRECTORY_DOWNLOADS))+"/"+ nameFILE)), "application/vnd.ms-excel"); 
    target.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP); 

    Log.v("OPEN_FILE_PATH", getExternalFilesDir(Environment.DIRECTORY_DOWNLOADS) + "/" + nameFILE); 
    startActivity(target); 

Als ich debbuger verwenden: Ich bin hier, nach dem Absturz

try { 
       mResolvedMethod.invoke(mResolvedContext, v); 
      } catch (IllegalAccessException e) { 
       throw new IllegalStateException(
         "Could not execute non-public method for android:onClick", e); 
      } catch (InvocationTargetException e) { 
       throw new IllegalStateException(
         "Could not execute method for android:onClick", e); 
      } 

Mein AndroidManifest.xml hat:

<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />

Sie haben für Berechtigungen auf Anwendung starten

ActivityCompat.requestPermissions(MainActivity.this, new String[]{Manifest.permission.READ_EXTERNAL_STORAGE, Manifest.permission.WRITE_EXTERNAL_STORAGE, 1);
