i trying view file word .txt file using android 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);

the issue trying give access via intents 3rd party applications doesn't have permission access files. android's security model doesn't allow other app access private data (assets/resources ....) root here exception.

so make file available such apps consider copying files public directory cachedir maybe suitable option.

by doing can use intents view data way using them right now. more copying files external dir here:

android: how copy files in assets sdcard

also while @ take @ android's security model

p.s don't forget write_external_storage permession..

good luck
