无法使用Intent.ACTION\u视图在Android上打开excel文件

我不知道这是什么原因,也无法在网上找到任何相关信息。 我使用的是来自 here 支持我的目标SDK 28。

我的导出方法:

 public void onExport(View view){
        try {
            //write changes to excel file(changes made outide of function)
            workbook.write();
            workbook.close();
            Toast.makeText(getApplication(),
                    "Data Exported to Excel Sheet", Toast.LENGTH_SHORT).show();
            findViewById(R.id.btn_export).setEnabled(false);

            //set file to saved excel file
            File file = new File(Environment.getExternalStorageDirectory(),
                    race.getName()+".xls");
            Uri path = FileProvider.getUriForFile(getApplicationContext(), "com.something.racecalculator.fileprovider", file);
            Intent intent = new Intent(Intent.ACTION_VIEW);
            Log.i("path: ", path.toString());
            intent.setDataAndType(path, "image/jpg");
            intent.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);
            intent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
            startActivity(intent);

        } catch (IOException e) {
            e.printStackTrace();
        } catch (WriteException e) {
            e.printStackTrace();
        }
        catch (ActivityNotFoundException e) {
            Log.i("oh no:", "No application available to view excel");
        }
 }

AndroidManifest.xml中的My provider标记(设置为的子项):

<provider
            android:name=".GenericFileProvider"
            android:authorities="com.something.racecalculator.fileprovider"
            android:exported="false"
            android:grantUriPermissions="true">
            <meta-data
                android:name="android.support.FILE_PROVIDER_PATHS"
                android:resource="@xml/provider_paths"/>
        </provider>
