No Activity found to handle intent error

Question

I am trying to view a file word as well as .txt file using android as follows:

Intent intent = new Intent(Intent.ACTION_VIEW);
intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
intent.setDataAndType(Uri.parse("file:///android_asset/usage.txt"), "plain/text");
getApplicationContext().startActivity(intent);

and

Intent intent = new Intent(Intent.ACTION_VIEW);
intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
intent.setDataAndType(Uri.parse("file:///android_asset/USAGE_INSTRUCTIONS_FOR_SMART_RESPONDER.doc"), "plain/text");
getApplicationContext().startActivity(intent);

inside a method of an activity. Now, i have ES File Manager installed on my device. But i keep on getting the error:

Answer 1

The issue is that you are trying to give access via intents to 3rd party applications that doesn't have permission to access your files. Android's Security Model doesn't allow any other app to access your private data (assets/resources ....) root here is an exception.

So to make your file available to such apps consider copying your files to a public directory CacheDir maybe the most suitable option.

by doing so you can use intents to view your data the way you are using them right now. for more about copying files to external dir look here:

Android: how to copy files in assets to sdcard

Also while at it take a look at Android's Security Model

P.S don't forget about WRITE_EXTERNAL_STORAGE permession..

Good luck

Answer 2

Exception says that File not exist. Watch that you are pointing to /android_asset/ folder in internal memory.

Are you sure that you not put this file on SDCard?

Answer 3

As is mentioned in the exception log,

java.io.FileNotFoundException: /android_asset/USAGE_INSTRUCTIONS_FOR_SMART_RESPONDER.doc: open failed: ENOENT (No such file or directory)

its not able to find the file. Verify if the file is indeed there in that location. Also, as Brigham mentioned, use text/plain.

Answer 4

You should use text/plain instead of plain/text.
