Trouble with the SelectFile library (Android mode)

mmuylle

When running the SelectFile library example I get a Fatal Exception error. Can someone explain me why? Thanks.

import select.files.*;

SelectLibrary files;

void setup() { size(320, 240);

files = new SelectLibrary(this);

files.selectInput("Select a file to process:", "fileSelected"); // files.selectFolder("Select a folder to process:", "fileSelected"); // files.selectOutput("Save the file please:", "fileSelected"); }

void fileSelected(File selection) { if (selection == null) { println("Nothing was selected."); } else { println("User selected " + selection.getAbsolutePath()); } }

@mmuylle===

• what version of processing???
• is this lib supposed to work in android mode?

mmuylle

Processing 3.0.1 the library was developed for processing in android mode: see http://andrusiv.com/android-select-file/

mmuylle

the example that I showed is the one that comes with the library .

@mmuylle=== looking to your link i see::

It is specifically designed for Android mode in Processing 2.0.

mmuylle

Thanks, and this is good to know but doesn't solve the problem. Are you aware of any files selection library that works in processing 3.0.1 android mode?

akenaton

@mmuylle=== i dont know wether it exists some lib for that; anyway, if you only want to select a file or a folder, java (or java android) can do that without any lib...

matthieu

Same problem as you, even with processing 2. I suppose that android doesn't found the path of the method select.files.SelectLibrary.selectImpl. I tried with all permissions and the bug is not there. No idea, do you find a solution with java ?

@mattieu && mmuylle:: where are your files??? on the sdcard??? in some specific folder??? do you know the uri for the folder??? - Places where you can put files and get them selecting are not at all like on a computer!

mmuylle

When testing the program from the computer in processing/android mode; I suppose the the path to the files is identical as when testing in java mode. If not, where can I find the instructions how to organise the files on the sdcard. thanks

matthieu

I thought I will have a selector panel to can choose my file in the folders on my tab, like selectInput() on my laptop

@matthieu=== not at all, the path to the files on the phone is very different: internal, external storage & so on. @mmuylle=== you put your files on the sdcard then in order that the user can select you have to use an Intent with Action_Get_Content, categoryOpenable and start ActivityForResult; see the android doc here:
