I didn’t had any other way to ask this question, So here is my problem:
I have a library project that I use for two applications and its working well. Now I have common login page and login functionality for both the applications and to avoid duplicating the code I want to use same login activity for both the applications. here is code that I use
library project
public class CanteenPreference {
// Static variables declaration
private static final String KEY_INSTANCE_URL = "instance_url";
private static final String KEY_USER_NAME = "user_name_preferences";
private static final String KEY_ACCESS_KEY = "access_key_preferences";
public static final String DEFAULT_URL = "some url";
private static final String URL_SUFFIX = "/api/call";
/**
* Gets the preferred url.
*
* @param activity
* @return
*/
public static String getUrl(Activity activity){
SharedPreferences sharedPrefs = PreferenceManager.getDefaultSharedPreferences(activity.getApplicationContext());
String previousURL = sharedPrefs.getString(KEY_INSTANCE_URL, null);
if (previousURL == null) {
Intent in=new Intent(activity,LoginActivity.class);
activity.startActivity(in);
previousURL = sharedPrefs.getString(KEY_INSTANCE_URL, DEFAULT_URL + URL_SUFFIX);
}
return previousURL;
}
/**
* Gets the preferred user name.
*
* @param activity
* @return
*/
public static String getUserName(Activity activity){
SharedPreferences sharedPrefs = PreferenceManager.getDefaultSharedPreferences(activity.getApplicationContext());
String previousUsername = sharedPrefs.getString(KEY_USER_NAME, null);
if (previousUsername == null) {
activity.startActivity(new Intent(activity, LoginActivity.class));
previousUsername = sharedPrefs.getString(KEY_USER_NAME, "test");
}
return previousUsername;
}
/**
* Gets the preferred password.
*
* @param activity
* @return
*/
public static String getPassword(Activity activity){
SharedPreferences sharedPrefs = PreferenceManager.getDefaultSharedPreferences(activity.getApplicationContext());
String previousPassword = sharedPrefs.getString(KEY_ACCESS_KEY, null);
if (previousPassword == null) {
activity.startActivity(new Intent(activity, LoginActivity.class));
previousPassword = sharedPrefs.getString(KEY_ACCESS_KEY, "test");
}
return previousPassword;
}
/**
* Writes the preferences
*
* @param activity
* @param url
* @param userName
* @param password
* @return true if committed
*/
public static boolean write(Activity activity, String url, String userName, String password){
SharedPreferences sharedPrefs = PreferenceManager.getDefaultSharedPreferences(activity.getApplicationContext());
SharedPreferences.Editor prefEditor = sharedPrefs.edit();
prefEditor.putString(KEY_INSTANCE_URL, url + URL_SUFFIX);
prefEditor.putString(KEY_USER_NAME, userName);
prefEditor.putString(KEY_ACCESS_KEY, password);
return prefEditor.commit();
}
}
and loginactivity in library
public class LoginActivity extends Activity {
private EditText mUrlInput;
private EditText mUserInput;
private EditText mPasswordInput;
private Button mButton;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.login_page);
mButton = (Button) findViewById(R.id.loginButt);
mUrlInput = (EditText) findViewById(R.id.urlInput);
mUserInput = (EditText) findViewById(R.id.userInput);
mPasswordInput = (EditText) findViewById(R.id.passwordInput);
mUrlInput.setText(CanteenPreference.DEFAULT_URL);
mButton.setOnClickListener(new OnClickListener() {
public void onClick(View v) {
final String url = mUrlInput.getText().toString();
final String userName = mUserInput.getText().toString();
final String password = mPasswordInput.getText().toString();
if (url == null || url.length() == 0 || userName == null
|| userName.length() == 0 || password == null
|| password.length() == 0) {
Toast toast = Toast.makeText(LoginActivity.this,
"All fields are required", Toast.LENGTH_SHORT);
toast.show();
} else {
Thread loginThread = new Thread() {
@Override
public void run() {
try {
DefaultHttpClient httpClient = new DefaultHttpClient();
HttpPost httpPost = new HttpPost(url);
List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>();
nameValuePairs.add(new BasicNameValuePair(
"username", userName));
nameValuePairs.add(new BasicNameValuePair(
"password", password));
httpPost.setEntity(new UrlEncodedFormEntity(
nameValuePairs));
HttpResponse httpResponse = httpClient
.execute(httpPost);
if (httpResponse.getStatusLine()
.getStatusCode() != HttpStatus.SC_OK) {
throw new Exception("Invalid credentials !");
}
} catch (Exception e) {
Log.d("Login: ", "Invalid credentials", e);
Toast toast = Toast.makeText(
LoginActivity.this,
"Invalid credentials",
Toast.LENGTH_SHORT);
toast.show();
}
// write the preferences
CanteenPreference.write(LoginActivity.this, url,
userName, password);
// finish the activity
LoginActivity.this.finish();
}
};
loginThread.start();
}
}
});
}
}
I have defined Login activity in both application and library manifest still I get following logcat`

Try to remove the

into
The
.means that this is part of the package of your Manifest which in your case is wrong.
