android.content.ActivityNotFoundException：未找到任何处理Intent的活动{act = android.intent.action.GET_CONTENT

Question

I'm trying to open the screenshots photos folder.

        private void Try3()
        {
            File dir = new File(Environment.getExternalStorageDirectory().getAbsolutePath() + "/Pictures/Screenshots");
            Log.d("File path ", dir.getPath());
            String dirPath=dir.getAbsolutePath();
            if(dir.exists() && dir.isDirectory()) {
                Intent intent = new Intent(Intent.ACTION_GET_CONTENT, null);
                intent.setType("image/*");
                intent.setData(Uri.fromFile(dir));

                Log.d("b4performSpecificCrop_startActivityForResult::", Integer.toString(3));
                startActivityForResult(intent, 3);
                Log.d("afterperformSpecificCrop_startActivityForResult::", Integer.toString(3));
            }             

I have this permission in the Manifest:

<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE"/>

and get this from logCat:

Update:

ACTION_VIEW doesn't work

ACTION_GET_CONTENT doesn't work

ACTION_PICK works, but I prefer the default photos Gallery view

I have read about these in the documentation, but didn't fully understand the difference between them. Can someone clear this out?

Answer 1

First, setData() wipes out your setType() IIRC. When you actually need both (hint: not here), set them both together with setDataAndType() .

Second, ACTION_GET_CONTENT is for choosing by type, not location. Quoting the documentation for ACTION_GET_CONTENT :

Note that no URI is supplied in the intent, as there are no constraints on where the returned data originally comes from

Hence, you will need to remove your setData() call and just use setType() . However, that will not pick from that folder.

ACTION_PICK is where you specify a collection to pick from, rather than a type. However, there is no guarantee that there will be an app on the device that supports ACTION_PICK for a file:// Uri .

I would recommend that you implement the UI in your application directly.
