    copied!<p>I have code to show a toast:</p> <pre><code>public void checkchallenge(View v) { String algo = null; if(algo == "123") { Context context = getApplicationContext(); CharSequence text = "You have " + messages ; int duration = Toast.LENGTH_SHORT; Toast toast = Toast.makeText(context, text, duration); toast.show(); ... </code></pre> <p>the error in eclipse that I am getting is:</p> <blockquote> <p>messages cannot be resolved to a variable</p> </blockquote> <p>The variable "messages" is being called in some code above it:</p> <pre><code>String messages = c.getString(TAG_MESSAGES); final TextView messages1 = (TextView)findViewById(R.id.envelope); </code></pre> <p>Maybe it's because I don't know Java too well but why isn't my string variable "messages" or "messages1" getting recognized in my code? I have a feeling it has to do with permissions of the code but when I remove the "final" part off of the messages 1 TextView I get the same error.</p> <p>Confused!</p> <pre><code>Here is the entire code to the class: public class Homepage extends Activity { //URL to get JSON Arrays public static String url = "http://10.0.2.2/android/SQL.php?username='"; public static String usernamefromlogin; public static TextView errorchecking; //JSON Node Names private static final String TAG_USER = "users"; private static final String TAG_WINS = "wins"; private static final String TAG_MESSAGES = "messages"; private static final String TAG_NAME = "fullname"; private static final String TAG_DISPLAY = "displayname"; private static final String TAG_EMAIL = "email"; private static final String TAG_PW = "password"; private static final String TAG_CREATED = "created_at"; private static final String TAG_UPDATED = "updated_at"; JSONArray user = null; //disable back button @Override public void onBackPressed() { } @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.reshomepage); //Get login name from EditText in login screen and concatenate it to PHP user-name for _GET command in 3 steps. //Step 1: Get intent from previous activity Intent intent = getIntent(); getIntent().getExtras(); //Step 2: convert intent (intent) to string called "usernamefromlogin" //error checking in log cat to see value of "usernamefromlogin" usernamefromlogin = intent.getExtras().getString("username2"); Log.d("log of usernamefromlogin", usernamefromlogin); //Step 3: take the string "url" and add string "usernamefromlogin" after it String url5 = url.concat(usernamefromlogin); String url6 = url5.concat("'"); //find TextView "errorchecking" and send the string "url6" to it so it can display in log cat Log.d("log of URL6 in it's final state", url6); // Creating new JSON Parser JSONParser jParser = new JSONParser(); // Getting JSON from URL from the final string "url6" JSONObject json = jParser.getJSONFromUrl(url6); //Logcat check value for TAG_USER try { // Getting JSON Array user = json.getJSONArray(TAG_USER); JSONObject c = user.getJSONObject(0); // Storing JSON item in a String Variable String name = c.getString(TAG_NAME); String messages = c.getString(TAG_MESSAGES); String wins = c.getString(TAG_WINS); String display = c.getString(TAG_DISPLAY); String email = c.getString(TAG_EMAIL); String pw = c.getString(TAG_PW); String created = c.getString(TAG_CREATED); String updated = c.getString(TAG_UPDATED); //Importing TextView final TextView name1 = (TextView)findViewById(R.id.tvfullname); TextView messages1 = (TextView)findViewById(R.id.envelope); final TextView wins1 = (TextView)findViewById(R.id.wins); final TextView created1 = (TextView)findViewById(R.id.tvcreated_at); final TextView updated1 = (TextView)findViewById(R.id.tvupdated_at); //Set JSON Data in its respectable TextView name1.setText("Hello " + name); updated1.setText("Your last login was " + updated); // print error if applicable. } catch (JSONException e) { e.printStackTrace(); } } public void checkchallenge(View v) { String algo = null; if(algo == "123") { // display pop up message (toast) Context context = getApplicationContext(); CharSequence text = "You have " + messages1 ; int duration = Toast.LENGTH_SHORT; Toast toast = Toast.makeText(context, text, duration); toast.show(); }else { // display pop up message (toast) Context context = getApplicationContext(); CharSequence text = "You have no new Challenges"; int duration = Toast.LENGTH_SHORT; Toast toast = Toast.makeText(context, text, duration); toast.show(); } } } </code></pre>
