Open the File Manager from an android app

Question

How can I redirect my app to open the File manager at a specific path ?

I've tried something like:

Intent shareIntent = new Intent(android.content.Intent.ACTION_SEND);
    shareIntent.setType("*/*");
    shareIntent.putExtra(Intent.EXTRA_STREAM,
            Uri.fromFile(new File(filePath)));
    shareIntent.setPackage("my.package");
    startActivity(shareIntent);

But I keep get the error:

E/AndroidRuntime(3591): android.content.ActivityNotFoundException: No Activity found to handle Intent { act=android.intent.action.SEND typ=/ flg=0x1 pkg=my.package (has clip) (has extras) }

What is the correct intent filter, as I suspect ACTION_SEND is not the correct one.

Thank you.

Answer 1

You can use Intent.ACTION_GET_CONTENT:

Intent intent = new Intent(Intent.ACTION_GET_CONTENT);
Uri uri = Uri.parse("/whatever/path/you/want/"); // a directory
intent.setDataAndType(uri, "*/*");
startActivity(Intent.createChooser(intent, "Open folder"));

Actually this days it's more like:

// Construct an intent for opening a folder
Intent intent = new Intent(Intent.ACTION_VIEW);
intent.setDataAndType(Uri.parse(aDownloadFolder), "resource/folder");
// Check that there is an app activity handling that intent on our system
if (intent.resolveActivityInfo(aContext.getPackageManager(), 0) != null) {
    // Yes there is one start it then
    startActivity(intent);
} else {
    // Did not find any activity capable of handling that intent on our system 
    // TODO: Display error message or something    
}
