Can't Open External Storage File In Android N Using Fileprovider
I am having trouble opening file inside external storage with Android N. File path file:///storage/emulated/0/Download/SamplePDFFile_5mb.pdf Initial implementation Perfectly w
Solution 1:
publicvoidgetGROUPSTORAGEPremission(){
inthasWriteContactsPermission= Splash_activity.this.checkSelfPermission(Manifest.permission_group.STORAGE);
if (hasWriteContactsPermission != PackageManager.PERMISSION_GRANTED) {
Splash_activity.this.requestPermissions(newString[]{ Manifest.permission_group.STORAGE},
PERMISSION_GROUPSTORAGE);
} else {
Filefile=newFile(Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_DOWNLOADS), "SamplePDFFile_5mb.pdf");
//old way//Uri uri = Uri.fromFile(file);//new wayUriuri= FileProvider.getUriForFile(MainActivity.this, getPackageName() + ".provider", file);
Intentintent=newIntent(Intent.ACTION_VIEW);
intent.setDataAndType(uri, "application/pdf");
intent.setFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);
startActivity(intent);
}
}
@OverridepublicvoidonRequestPermissionsResult(int requestCode, @NonNull String[] permissions, @NonNullint[] grantResults) {
super.onRequestPermissionsResult(requestCode, permissions, grantResults);
if (requestCode == PERMISSION_GROUPSTORAGE) {
if (grantResults[0] == PackageManager.PERMISSION_GRANTED) {
// Permission GrantedFilefile=newFile(Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_DOWNLOADS), "SamplePDFFile_5mb.pdf");
//old way//Uri uri = Uri.fromFile(file);//new wayUriuri= FileProvider.getUriForFile(MainActivity.this, getPackageName() + ".provider", file);
Intentintent=newIntent(Intent.ACTION_VIEW);
intent.setDataAndType(uri, "application/pdf");
intent.setFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);
startActivity(intent);
} else {
// Permission Denied//Toast.makeText(mContext, "PERMISSION_GROUPSTORAGE Denied", Toast.LENGTH_SHORT).show();
}
}
}
After N need to check runtime permission .
Solution 2:
Maybe late, but I solved it by adding an temporary permission to the intent, by doing the following:
Uripath= FileProvider.getUriForFile(MainActivity.this, "com.example.root.somepackage.provider", pdfFile);
IntentpdfIntent=newIntent(Intent.ACTION_VIEW);
pdfIntent.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION); // GRANT TEMPORARY READ PERMISSION
pdfIntent.setDataAndType(path, "application/pdf");
try{
startActivity(pdfIntent);
}

This simple solution helps me to solve this kind of problems. Hope it will help you and save your time.
publicvoidopen_file(String filename) {
Filepath=Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_DOWNLOADS);
Filefile=newFile(path, filename);
// Get URI and MIME type of fileUriuri= FileProvider.getUriForFile(context, context.getApplicationContext().getPackageName() + ".fileprovider", file);
Stringmime= context.getContentResolver().getType(uri);
// Open file with user selected appIntentintent=newIntent();
intent.setAction(Intent.ACTION_VIEW);
intent.setDataAndType(uri, mime);
intent.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);
context.startActivity(intent);
}
