Android calls system installed software to open file (go)

Android calls system installed software to open file (go)

In the application how to call the system installed software to open a file, this is the problem we often encounter, the following is a way I used to share with you!

This is a way to open the file:

Java code

2. /**
4. * Open File
6. * @param file
8. */
10. Private void OpenFile (file file) {
14. Intent Intent = new Intent ();
16. Intent.addflags (Intent.flag_activity_new_task);
18. //Set the Action property of Intent
20. Intent.setaction (Intent.action_view);
22. //Get MIME type of file
24. String type = getmimetype (file);
26. //Set the data and type properties of the intent.
28. Intent.setdataandtype (/*uri*/uri.fromfile (file), type);
30. //Jump
32. StartActivity (Intent);
36. }
40. /**
42. * The corresponding MIME type is obtained according to the file suffix name.
44. * @param file
46. */
48. Private String getmimetype (file file) {
52. String type="*/*";
54. String fName = File.getname ();
56. //Get the delimiter "." Before the suffix name.  The position in the fname.
58. int dotindex = Fname.lastindexof (".");
60. if (Dotindex < 0) {
62. return type;
64. }
66. /* Get the suffix name of the file */
68. String end=fname.substring (Dotindex,fname.length ()). toLowerCase ();
70. if (end=="")return type;
72. //The corresponding MIME type is found in the MIME and file type match table.
74. For (int i=0;i<mime_maptable.length;i++) { //mime_maptable??  You must have a question here, what is this mime_maptable?
76. if (end.equals (mime_maptable[i][0]))
78. Type = mime_maptable[i][1];
80. }
82. return type;
84. }

Mime_maptable is a string array of MIME types that correspond to the suffix names of all files:

Java code

2. Private final string[][] mime_maptable={
4. //{suffix name, MIME type}
6. {". 3gp", "VIDEO/3GPP"},
8. {". apk", "Application/vnd.android.package-archive"},

This MIME type may not be complete, do you have anything to add?
