How to open Gallery to pick an image?

Question

I am looking for a way to open onClick the gallery to pick an Picture. I want to use that local "uploaded" picture in a listview of pictures. Can someone help and explain me how to do that. I am a beginner in Android Developing.

public void pickImage() {
    Intent intent = new Intent(Intent.ACTION_GET_CONTENT);
    intent.setType("image/*");
    startActivityForResult(intent, PICK_PHOTO_FOR_AVATAR);
}

@Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);
    if (requestCode == PICK_PHOTO_FOR_AVATAR && resultCode == Activity.RESULT_OK) {
        if (data == null) {
            //Display an error
            return;
        }
        InputStream inputStream = context.getContentResolver().openInputStream(data.getData());
        //Now you can do whatever you want with your inpustream, save it as file, upload to a server, decode a bitmap...
    }
}

From where do you get `context` variable in `onActivityResult` function? Replace `context` with `YourActivityName.this`. Or if you have this code in fragment use `getActivity()` function instead. — BVantur, Oct 18 '17 at 12:55
And when i delete the line with context i get mSecurityInputMethodService is null — Supito, Oct 18 '17 at 12:55
`InputStream inputStream = YourActivityName.this.getContentResolver().openInputStream(data.getData());` YourActivityName is name of your Activity. — BVantur, Oct 18 '17 at 12:58

Here is a code i used in my app

Intent pickImageIntent = new Intent(Intent.ACTION_PICK, MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
startActivityForResult(pickImageIntent, PICKIMAGE_REQUESTCODE);

And at the onActivity result method

 protected void onActivityResult(int requestCode, int resultCode, Intent data) {

            super.onActivityResult(requestCode, resultCode, data);
            if (requestCode == PICKIMAGE_REQUESTCODE) {
                if (resultCode == RESULT_OK) {
                    Uri imageUri = data.getData();
                    InputStream inputStream = null;


                    try {
                        inputStream = getContentResolver().openInputStream(imageUri);
                       bitmap = BitmapFactory.decodeStream(inputStream);
                    } 
                   catch (FileNotFoundException e) 
                     {
                        e.printStackTrace();
                    } finally {
                        try {
                            inputStream.close();
                        } catch (IOException e) {
                            e.printStackTrace();
                            Log.d(TAG, "onActivityResult: error closing InputStream during reading image from the phone external storage");
                        }

                    }
    }
