Ionic更新APP後通過fileOpener開啟安裝完成後，沒有提示視窗（開啟或完成），比如你下載一個APP安裝成功後會給你一個反饋結果介面，接著你是要直接開啟APP呢就點選（開啟），你要是不想開啟呢就點選（完成），等你下次想用的時候開啟就行，就是這麼個反饋視窗。

處理方法：

找到platforms下的Android原始碼，找到fileOpener的Java類，新增如下程式碼：

一般該類目錄為：io.github.pwlin.cordova.plugins.fileopener2;

intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);

private void _open(String fileArg, String contentType, Boolean openWithDefault, CallbackContext callbackContext) throws JSONException {
    String fileName = "";
    try {
      CordovaResourceApi resourceApi = webView.getResourceApi();
      Uri fileUri = resourceApi.remapUri(Uri.parse(fileArg));
      fileName = this.stripFileProtocol(fileUri.toString());
    } catch (Exception e) {
      fileName = fileArg;
    }
    File file = new File(fileName);
    if (file.exists()) {
      try {
        Uri path = Uri.fromFile(file);
        Intent intent = new Intent(Intent.ACTION_VIEW);
        if ((Build.VERSION.SDK_INT >= 23 && !contentType.equals("application/vnd.android.package-archive")) || ((Build.VERSION.SDK_INT == 24 || Build.VERSION.SDK_INT == 25) && contentType.equals("application/vnd.android.package-archive"))) {

          Context context = cordova.getActivity().getApplicationContext();
          path = FileProvider.getUriForFile(context, cordova.getActivity().getPackageName() + ".opener.provider", file);
          intent.setDataAndType(path, contentType);
          intent.setFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);
          intent.setFlags(Intent.FLAG_ACTIVITY_NO_HISTORY);
          intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);//不加此句安裝成功後不會自動開啟安裝成功後介面
 

          //intent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);

          List<ResolveInfo> infoList = context.getPackageManager().queryIntentActivities(intent, PackageManager.MATCH_DEFAULT_ONLY);
          for (ResolveInfo resolveInfo : infoList) {
            String packageName = resolveInfo.activityInfo.packageName;
            context.grantUriPermission(packageName, path, Intent.FLAG_GRANT_WRITE_URI_PERMISSION | Intent.FLAG_GRANT_READ_URI_PERMISSION);
          }
        } else {
          intent.setDataAndType(path, contentType);
          intent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
          intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);//不加此句安裝成功後不會自動開啟安裝成功後介面
 

        }
        /*
         * @see
         * http://stackoverflow.com/questions/14321376/open-an-activity-from-a-cordovaplugin
         */
        if (openWithDefault) {
          cordova.getActivity().startActivity(intent);
        } else {
          cordova.getActivity().startActivity(Intent.createChooser(intent, "Open File in..."));
        }

        callbackContext.success();
      } catch (android.content.ActivityNotFoundException e) {
        JSONObject errorObj = new JSONObject();
        errorObj.put("status", PluginResult.Status.ERROR.ordinal());
        errorObj.put("message", "Activity not found: " + e.getMessage());
        callbackContext.error(errorObj);
      }
    } else {
      JSONObject errorObj = new JSONObject();
      errorObj.put("status", PluginResult.Status.ERROR.ordinal());
      errorObj.put("message", "File not found");
      callbackContext.error(errorObj);
    }
  }
 

如上，紅色部分即為需要修改的原始碼部分；

PS：Android專案下遇到此問題，只需在啟動APP是新增如上紅色部分即可；
