Accessing another third party app in android

How to access开发者_高级运维 another third party application from my application in android?

You must start by creating an intent. If the activity launched has to return a result, you start your activity by calling the method startActivityForResult, and you will receive the result in the method onActivityResult. If you aren't waiting result from this activity, just call startActivity.

In those method calls, you 'll have to pass your intent in the parameters.

In this example, i call the android gallery to allow the user to choose an image.

protected void chooseImage()
        {
            Intent intent = new Intent();
            intent.setType("image/*");
            intent.setAction(Intent.ACTION_GET_CONTENT);
            startActivityForResult(Intent.createChooser(intent,
                    "Select Picture"), ACTIVITY_CHOOSE_IMAGE);
        }

Then, i receive the image choosen by the user, resulting of the previous activity:

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

        if (resultCode == RESULT_OK) {
            if (requestCode == ACTIVITY_CHOOSE_IMAGE) {
                //Traitement sur l'image

            }
        }

    }
