android为第三方库添加许可证

Question

I'm creating a new app using Android studio, and I used 3rd party library as in jar file.

I know I need to add license for library, but I don't know how to do that.

My questions

• do I need to add license in code or create new license file?
• how to do that?

Answer 1

Here I suggest you to show License first time after installation of app.

Put

liesence.txt

file in your

assets folder

Read this file using following code:

String message = "";
try{
            AssetManager am = getApplicationContext().getAssets();
            InputStream is = am.open("licence.txt");
            InputStreamReader inputStreamReader = new InputStreamReader(is, "UTF-8");
            BufferedReader bufferedReader = new BufferedReader(inputStreamReader);
            String receiveString = "";
            StringBuilder stringBuilder = new StringBuilder();

            while ( (receiveString = bufferedReader.readLine()) != null ) {
                if(receiveString.equals("")){
                    stringBuilder.append(System.getProperty("line.separator"));
                }else{
                    stringBuilder.append(receiveString);
                }
            }
            is.close();
            message = stringBuilder.toString();
        } catch (IOException e) {e.printStackTrace();}

And then show this message in AlertDialog
