I am trying to open a PDF file that I downloaded and saved to external storage. But when I open my application, it crashes and shows the following error;

The following is my asynchronous task, where I download this PDF file and try to open it.
package myPackageName.common.postData; public class DownloadFileFromURL extends AsyncTask<String, String, String> { private ProgressDialog Dialog; private Context mContext; private String folder_main; //= "TermCondition"; private String fileName;//= "termCondition.pdf"; String urlString; public DownloadFileFromURL(Context mContext, String folderName) { this.mContext = mContext; this.folder_main = folderName; Dialog = new ProgressDialog(this.mContext); } @Override protected String doInBackground(String... f_url) { try { urlString = f_url[0]; URL url = new URL(f_url[0]); File folder = new File(Environment.getExternalStorageDirectory(), this.folder_main); if (folder.exists()) { folder.mkdirs(); } HttpURLConnection urlConnection = (HttpURLConnection) url.openConnection(); urlConnection.connect(); InputStream inputStream = urlConnection.getInputStream(); FileOutputStream fileOutputStream = new FileOutputStream(Environment.getExternalStorageDirectory() + "/" + "default.pdf"); int totalSize = urlConnection.getContentLength(); byte[] buffer = new byte[AccessibilityNodeInfoCompat.ACTION_DISMISS]; while (true) { int bufferLength = inputStream.read(buffer); if (bufferLength <= 0) { break; } fileOutputStream.write(buffer, 0, bufferLength); } fileOutputStream.close(); } catch (FileNotFoundException e) { FileLog.e(mContext.getClass().getName(), e); } catch (MalformedURLException e2) { FileLog.e(mContext.getClass().getName(), e2); } catch (IOException e3) { FileLog.e(mContext.getClass().getName(), e3); } return null; } public void showPdf() { try { File file = new File(Environment.getExternalStorageDirectory() + "/" + "default.pdf"); try { Intent intent = new Intent(); intent.setAction(Intent.ACTION_VIEW); if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.N) { intent.setFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION); Uri contentUri = FileProvider.getUriForFile(mContext, "medimanage.corporate.mobile.fileprovider", file); intent.setDataAndType(contentUri, "application/pdf"); } else { intent.setDataAndType(Uri.fromFile(file), "application/pdf"); } mContext.startActivity(intent); } catch (ActivityNotFoundException anfe) { Toast.makeText(mContext, "No activity found to open this attachment.", Toast.LENGTH_LONG).show(); } } catch (Exception e) { FileLog.e(mContext.getClass().getName(), e); } } @Override protected void onPreExecute() { Dialog.setMessage("Downloading..."); Dialog.setCancelable(false); Dialog.setCanceledOnTouchOutside(false); Dialog.show(); } @Override protected void onPostExecute(String s) { this.Dialog.dismiss(); showPdf(); super.onPostExecute(s); } }
Following is AndroidManifest.xml
<application ...> <provider android:name="android.support.v4.content.FileProvider" android:authorities="myPackageName.fileprovider" android:exported="false" android:grantUriPermissions="true"> <meta-data android:name="android.support.FILE_PROVIDE_PATHS" android:resource="@xml/provider_paths" /> </provider> </application>
And provider_paths.xml has the following code;
<?xml version="1.0" encoding="utf-8"?> <paths> <external-path path="Android/data/" name="files_root" /> <external-path path="." name="external_storage_root" /> </paths>
I am trying to run the above code in API 19 and API 25, but it fails on both devices. I can’t find out where I am going wrong.
I submitted this question as well as this link, but could not find a solution to my problem.
