분명 저장은 잘되어있습니다. Abcd.pdf파일을 열고싶습니다.
근데 열면 위와같이 에러가납니다. 로그에서 Log.e("download","result : "+pdfUri.getPath()); 이부분을 찍어보면
/storage/emulated/0/Download/Abcd.pdf 잘만나옵니다..근데 왜 장치에 없다고나올까요.
File mypath=new File( Environment.getExternalStorageDirectory().getAbsolutePath() + "/Download/","Abcd.pdf");
Log.e("download",mypath.getAbsolutePath());
Uri pdfUri = FileProvider.getUriForFile(getApplicationContext(), getApplicationContext().getPackageName() + ".provider", mypath);
Log.e("download",mypath.exists()+"");
if (mypath.exists()) {
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.N) {
Log.e("download","result : "+pdfUri.getPath());
intent = new Intent(Intent.ACTION_VIEW);
intent.setType("application/pdf");
intent.putExtra(MediaStore.EXTRA_OUTPUT, pdfUri);
}else{
}
intent.addFlags(Intent.FLAG_ACTIVITY_NO_HISTORY);
intent.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);
try {
startActivity(intent);
}
catch (ActivityNotFoundException e) {
Log.e("error","error"+e);
}
}
