Question

I’m working on an Android app in which I have to open & close excel files on button click. These excel files will be readonly. After closing the excel file, it should direct me to the app.

Please suggest me a way to do this.

Answer 1

Android 7.0 Update:

Android 7.0 will throw FileUriExposedException if you try to open your app document with an external app. You need to implement FileProvider refer This Answer.

but here is a little more easier one.

open application

but i guess you have to find out the MIME TYPE.

EDIT

got the mime type as well

UPDATE

so something like this might work.

Intent intent = new Intent(Intent.ACTION_VIEW);
intent.setDataAndType(path, "application/vnd.ms-excel");
intent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);


try {
    startActivity(intent);
} 
catch (ActivityNotFoundException e) {
    Toast.makeText(OpenDoc.this, "No Application Available to View Excel", Toast.LENGTH_SHORT).show();
}
