How to Integrate Alfresco Login API With Standalone Native Android Application

Alfresco is a popular Enterprise Content Management (ECM) and Business Process Management (BPM) tool, widely used as a web application. With the increasing involvement of mobile devices in business use cases, the dependency of mobile devices in daily work has also been increased. As, we may be aware of the Alfresco Content Service Android Application available on the playstore, but sometimes client requirement leads us to develop a standalone application for the specific purpose like scanning barcodes from the mobile device and storing it to the Alfresco Repository or some other specific requirement.


Alfresco is based on RESTful APIs and can be communicated with other platforms via REST APIs easily. We can use Alfresco login REST API to integrate it with Android Application. This blog is a step-by-step guide to integrate Alfresco login API with Android.

            @Override
            public void onClick(View view) {
                try {
                    userLogin();
                } catch (Exception e) {

                }
            }
        });
    }
    public void userLogin(){
        final String siteurl = et_login_siteurl.getText().toString();
        final String username = et_login_username.getText().toString();
        final String password = et_login_password.getText().toString();
        UserLogin u = new UserLogin();
        u.execute("https://"+siteurl+"/alfresco/service/api/login?u="+username+"&pw="+password+"&format=json");
    }
    class UserLogin extends AsyncTask{
        @Override
        protected String doInBackground(String... params) {
            try{
                HttpClient httpclient;
                httpclient = new DefaultHttpClient();
                HttpResponse response;
                String responseString = null;
                JSONObject jsonReader = null;
                response = httpclient.execute(new HttpGet(params[0]));
                StatusLine statusLine = response.getStatusLine();
                if (statusLine.getStatusCode() == HttpStatus.SC_OK) {
                    ByteArrayOutputStream out = new ByteArrayOutputStream();
                    response.getEntity().writeTo(out);
                    out.close();
                    responseString = out.toString();
                    Log.d("------ResponseString--", responseString);
                    jsonReader = new JSONObject(responseString);
                    Intent i = new Intent(MainActivity.this, NextActivity.class);
	    //NextActivity.class shows the next screen you want to go 		    //after login
                    startActivity(i);
                }
            }catch(Exception e){
                    e.printStackTrace();
            }
