Android – use intent.action_ Pick open image

I'm trying to use intent.action_ Pick opens the image, but when I start the activity using startactivityforresoult, my application crashes. What clues did I do wrong?

    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;
    }
}

Log display:

resolvent:

ACTION_ Pick allows the user to select images from any installed application that has registered such operations. You cannot specify which album to select. The user can decide which application to use and browse to the desired album to select photos

So take out the folder parameters. You can try this:

Intent intent = new Intent(Intent.ACTION_PICK);
intent.setType("image/*");
intent.setAction(Intent.ACTION_GET_CONTENT);
startActivityForResult(intent, REQUEST_CODE_LOAD_IMAGE);

In onactivityresult, except result_ In addition to OK, you should also check data. Getdata()= Null, because the application can close correctly (without canceling) without returning the image at all
