l'ouverture d'une image à l'aide de l'Intention.ACTION_PICK

Je suis en train d'ouvrir une image à l'aide de l'intention.ACTION_PICK mais quand je démarre l'activité à l'aide de startActivityForResoult mon application se bloque. Des indices de ce que je fais de mal?

    public void button_load_image(View view) {
    String path = Environment.getExternalStorageDirectory()
            .getAbsolutePath() + "/" + SimpleCamera.getAlbumName();
    File f = new File(path);

    if (f.exists()) {
        Log.d("button_load_image", "folder exists");
        if (f.isDirectory()) {
            Log.d("button_load_image", "is directory");
            Uri u = Uri.fromFile(f);
            Intent intent = new Intent(Intent.ACTION_PICK, u);
            Log.d("Intent.ACTION_PICK", "IS CREATED");              
            startActivityForResult(intent, REQUEST_CODE_LOAD_IMAGE);                
        }
    }
}

protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    switch (requestCode) {
    case REQUEST_CODE_LOAD_IMAGE:
        if (resultCode == RESULT_OK) {
            Uri imageUri= data.getData();
            Log.d("image selected path", imageUri.getPath());
        }
        break;
    }
}

  • Vérifiez ce tutoriel, Il semble que ce est exactement ce que vous cherchez. blog.vogella.com/2011/09/13/...
  • Ce que j'essaie de faire est de permettre à l'utilisateur de choisir une image (previosly prises avec la même application) afin d'obtenir de l'Uri. Je vais utiliser l'uri-ci pour certains de traitement de l'image avec openCV
  • BTW, il y a aussi l'option de ACTION_OPEN_DOCUMENT : developer.android.com/guide/topics/providers/...
