I'm trying to get working a native android project that uses Worklight form based authentication. I'm already able to authenticate the user through the native APIs. The problem appears when I change between activities (intents). Once the user enters his information and submits the form, it is authenticated but the worklight server connection is lost.
This is the code:
MainActivity.java
public class MainActivity extends Activity {
private Button buttonConnect = null;
private Button buttonInvoke = null;
private static TextView textView = null;
private static MainActivity _this;
private MyChallengeHadler challengeHandler;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
_this = this;
buttonConnect = (Button)findViewById(R.id.buttonConnect);
buttonInvoke = (Button)findViewById(R.id.buttonInvoke);
textView = (TextView)findViewById(R.id.textView);
final WLClient client = WLClient.createInstance(this);
buttonConnect.setOnClickListener(new OnClickListener() {
public void onClick(View v) {
updateTextView("Connecting...");
client.connect(new MyConnectListener());
challengeHandler = new MyChallengeHadler(MainActivity.this, "BasicAuth");
client.registerChallengeHandler(challengeHandler);
}
});
buttonInvoke.setOnClickListener(new OnClickListener() {
public void onClick(View v) {
updateTextView("Invoking procedure...");
String adapterName = "RSSReader";
String procedureName = "getStoriesFiltered";
WLProcedureInvocationData invocationData =
new WLProcedureInvocationData(adapterName, procedureName);
Object[] parameters = new Object[] {"world"};
invocationData.setParameters(parameters);
WLRequestOptions options = new WLRequestOptions();
options.setTimeout(30000);
WLClient client = WLClient.getInstance();
client.invokeProcedure(invocationData, new MyInvokeListener(), options);
}
});
}
public static void updateTextView(final String str){
Runnable run = new Runnable() {
public void run() {
textView.setText(str);
}
};
_this.runOnUiThread(run);
}
}
LoginActivity.java
public class LoginActivity extends Activity {
private Button Submit = null;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_login);
Submit = (Button)findViewById(R.id.button1);
Submit.setOnClickListener(new OnClickListener() {
public void onClick(View v) {
MyChallengeHadler challengeHandler = new MyChallengeHadler(LoginActivity.this, "BasicAuth");
challengeHandler.submitLogin(0, "maria", "maria", false);
}
});
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.login, menu);
return true;
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
// Handle action bar item clicks here. The action bar will
// automatically handle clicks on the Home/Up button, so long
// as you specify a parent activity in AndroidManifest.xml.
int id = item.getItemId();
if (id == R.id.action_settings) {
return true;
}
return super.onOptionsItemSelected(item);
}
}
MyChallengeHadler.java
public class MyChallengeHadler extends ChallengeHandler {
private WLResponse cachedResponse;
private final Activity parentActivity;
public MyChallengeHadler(final Activity a, String realm) {
super(realm);
this.parentActivity =a;
// TODO Auto-generated constructor stub
}
#Override
public void onFailure(WLFailResponse arg0) {
// TODO Auto-generated method stub
}
#Override
public void onSuccess(WLResponse arg0) {
// TODO Auto-generated method stub
}
#Override
public boolean isCustomResponse(WLResponse response) {
if (response == null || response.getResponseText() == null
|| response.getResponseText().indexOf("j_security_check") == -1) {
return false;
}
return true;
}
#Override
public void handleChallenge(WLResponse response){
if (!isCustomResponse(response)) {
submitSuccess(response);
} else {
cachedResponse = response;
Intent login = new Intent(parentActivity, LoginActivity.class);
parentActivity.startActivityForResult(login, 1);
}
}
public void submitLogin(int resultCode, String userName, String password, boolean back){
HashMap<String, String> params = new HashMap<String, String>();
params.put("j_username", userName);
params.put("j_password", password);
submitLoginForm("/j_security_check", params, null, 0, "post");
Intent login = new Intent(parentActivity, MainActivity.class);
parentActivity.startActivityForResult(login, 1);
}
}
I have already solved my code's problem. I was using wrongly android's intents. This is the new version of the code:
LoginActivity.java
public class LoginActivity extends Activity {
private Button Submit;
private Intent result;
public static final String Back = "back";
public static final String UserNameExtra = "username";
public static final String PasswordExtra = "password";
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_login);
Submit = (Button)findViewById(R.id.button1);
result = new Intent();
Submit.setOnClickListener(new OnClickListener() {
public void onClick(View v) {
result.putExtra(UserNameExtra, "maria");
result.putExtra(PasswordExtra, "maria");
result.putExtra(Back, false);
setResult(RESULT_OK, result);
finish();
}
});
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.login, menu);
return true;
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
// Handle action bar item clicks here. The action bar will
// automatically handle clicks on the Home/Up button, so long
// as you specify a parent activity in AndroidManifest.xml.
int id = item.getItemId();
if (id == R.id.action_settings) {
return true;
}
return super.onOptionsItemSelected(item);
}
}

if you want to send the info to the next activity you can add it to the intent with a bundle.
ACTIVITY:
Intent i=new Intent(Activity.this, SecontActivity.class);
i.putExtra("email", email);
startActivity(i);
SecontActivity:
Intent intent = getIntent();
String email = intent.getStringExtra("email");
if you want the info in all your activities then save it in SharedPreferences
Activity:
SharedPreferences sharedPref = getActivity().getPreferences(Context.MODE_PRIVATE);
SharedPreferences.Editor editor = sharedPref.edit();
editor.putString("email", email);
editor.commit();
SecondActivity:
SharedPreferences sharedPref = getActivity().getPreferences(Context.MODE_PRIVATE);
String email = sharedPref.getString(email, defaultValue);
Store the info such as name, imageurl and other profile details in a database or (sharedpreferences as indicated here) for access across different activities. This information can be fetched at any stage once saved throughout the history of the app unless the data from the app is cleared.
I would go for the database as it would more structure and can potentially provide multi-user support, incase you want to implement profile switching in your app.
I have MainActivity with two String variables viz. filename & url.
I tried to use one download manager.
I dont know how to pass filename String from my Player Activity.
buttondownload = (TextView )findViewById(R.id.download);
buttondownload.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
DownloadHelper.addNewTask(Player.this, url,
new PreDownloadStatusListener() {
#Override
public void notFoundSDCard(int errorCode, String errorInfo) {
Toast.makeText(Player.this, "No SD Card", Toast.LENGTH_SHORT).show();
}
#Override
public void sdCardCannotWriteOrRead(int errorCode, String errorInfo) {
Toast.makeText(Player.this, "Not read and write SD card", Toast.LENGTH_SHORT).show();
}
#Override
public void moreTaskCount(int errorCode, String errorInfo) {
Toast.makeText(Player.this, "Task list is full", Toast.LENGTH_SHORT).show();
}
});
Intent intent1 = new Intent(Player.this, DownloadListActivity.class);
startActivity(intent1);
}
});
DownloadHelper.startAllTask(Player.this);
mReceiver = new DownloadReceiver();
IntentFilter filter = new IntentFilter();
filter.addAction(DownloadValues.Actions.BROADCAST_RECEIVER_ACTION);
registerReceiver(mReceiver, filter);
They call filename from another public class DownloadUtils.. How can i pass filname to DownloadUtils
I want Pass String from Player to ViewHolder.java
package com.download.main;
public class ViewHolder {
public static final int KEY_URL = 0;
public static final int KEY_SPEED = 1;
public static final int KEY_PROGRESS = 2;
public static final int KEY_IS_PAUSED = 3;
public TextView titleText;
public ProgressBar progressBar;
public TextView speedText;
public ImageButton pauseButton;
public ImageButton deleteButton;
public ImageButton continueButton;
private boolean hasInited = false;
public ViewHolder(View parentView) {
if (parentView != null) {
titleText = (TextView) parentView.findViewById(R.id.title);
speedText = (TextView) parentView.findViewById(R.id.speed);
progressBar = (ProgressBar) parentView.findViewById(R.id.progress_bar);
pauseButton = (ImageButton) parentView.findViewById(R.id.btn_pause);
deleteButton = (ImageButton) parentView.findViewById(R.id.btn_delete);
continueButton = (ImageButton) parentView.findViewById(R.id.btn_continue);
hasInited = true;
}
}
public static HashMap<Integer, String> getItemDataMap(String url, String speed, String progress, String isPaused) {
HashMap<Integer, String> item = new HashMap<Integer, String>();
item.put(KEY_URL, url);
item.put(KEY_SPEED, speed);
item.put(KEY_PROGRESS, progress);
item.put(KEY_IS_PAUSED, isPaused);
return item;
}
public void setData(HashMap<Integer, String> item) {
if (hasInited) {
titleText.setText(///////**I want here my my string calle "filename" from player Activity**//////);
speedText.setText(item.get(KEY_SPEED));
String progress = item.get(KEY_PROGRESS);
if (TextUtils.isEmpty(progress)) {
progressBar.setProgress(0);
}
else {
progressBar.setProgress(Integer.parseInt(progress));
}
if (Boolean.parseBoolean(item.get(KEY_IS_PAUSED))) {
onPause();
}
}
}
public void onPause() {
if (hasInited) {
pauseButton.setVisibility(View.GONE);
continueButton.setVisibility(View.VISIBLE);
}
}
public void setData(String url, String speed, String progress) {
setData(url, speed, progress, false + "");
}
public void setData(String url, String speed, String progress, String isPaused) {
if (hasInited) {
HashMap<Integer, String> item = getItemDataMap(url, speed, progress, isPaused);
titleText.setText(///////**I want here my my string calle "filename" from player Activity**//////);
speedText.setText(speed);
if (TextUtils.isEmpty(progress)) {
progressBar.setProgress(0);
}
else {
progressBar.setProgress(Integer.parseInt(item.get(KEY_PROGRESS)));
}
}
}
}
To pass any data from one activity to another use Intent. Example:-
Use below code in your Player.java class:-
Intent intent = new Intent(FromClass.this, ToClass.class);
intent.putExtra("filename", filename);
startActivity(intent);
Write the below code in the ViewHolder.java class:-
do not forget to extend Activity
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.yourLayoutName);
Intent intent = getIntent();
String filename= intent.getStringExtra("filename");
}
Then you can use filename in your setData() like this:-
public void setData(HashMap<Integer, String> item) {
if (hasInited) {
titleText.setText(filename);
speedText.setText(item.get(KEY_SPEED));
String progress = item.get(KEY_PROGRESS);
if (TextUtils.isEmpty(progress)) {
progressBar.setProgress(0);
}
else {
progressBar.setProgress(Integer.parseInt(progress));
}
if (Boolean.parseBoolean(item.get(KEY_IS_PAUSED))) {
onPause();
}
}
}
