            return null;
        }

        }
        // this is our fallback here
        return uri.getPath();


    }


}

How could I fix it?

Source of the issue

You can simplify your switch statement's case 0 a bit and pass selectedImageUri directly to the AviaryIntent's setData() method.

As a result, you won't need your getPath() helper method.

Example code

Below is working code, based on your code above, that will:

1. Open the image source chooser immediately
2. Open the selected image in the Creative SDK Image Editor
3. Attach the edited image to the ImageView

See the comments in the example code to find where these things happen.

public class MainActivity extends AppCompatActivity {

    private ImageView mSelectedImageView;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
        setSupportActionBar(toolbar);

        mSelectedImageView = (ImageView) findViewById(R.id.selectedImageView);

        // Open the image source chooser immediately
        Intent galleryIntent = new Intent();
        galleryIntent.setType("image/*");
        galleryIntent.setAction(Intent.ACTION_GET_CONTENT);
        startActivityForResult(Intent.createChooser(galleryIntent, "Select an image"), 0);

    }

    @Override
    protected void onActivityResult(int requestCode, int resultCode, Intent data) {
        super.onActivityResult(requestCode, resultCode, data);

        if (resultCode == RESULT_OK) {
            switch (requestCode) {

                // Open the Creative SDK Image Editor with the chosen image
                case 0:
                    Uri selectedImageUri = data.getData();
                    Intent imageEditorIntent = new AviaryIntent.Builder(this)
                            .setData(selectedImageUri)
                            .build();

                    startActivityForResult(imageEditorIntent, 1);

                    break;


                // Attach the edited image to the ImageView
                case 1:
                    Uri editedImageUri = data.getData();
                    mSelectedImageView.setImageURI(editedImageUri);

                    break;
            }
        }

    }

    // ...
}

回答2:

try to change true to false on your Activity in the manifest file.

android:noHistory="true" to android:noHistory="false"

回答3:

your code : galleryIntent.setAction(Intent.ACTION_GET_CONTENT)

Use this : Intent GalleryIntent = new Intent(Intent.ACTION_PICK, MediaStore.Images.Media.INTERNAL_CONTENT_URI);
