Intent localIntent = newIntent("android.intent.action.VIEW",uri);

intent.setPackage(packageName);  //指定应用市场

intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);

intent.setType("*/*");

intnet.addCategory(Intent.CATEGORY_OPENABLE);

startActivityForResult(intent,1);

 

protected void onActivityResult(intrequestCode,int resultCode,Intent data){

         if(resultCode==Activity.Result_OK){

                   Urirui=data.getData();

                   Filefile=new File(new URI(uri.toString()));

}

}
