Need help with a title menu

Hey everyone,
I'm working on a minesweeper-like game for my independent project in school this semester, but I'm running into a but of trouble with the title screen. What I'm trying to do is have a seperate activity launch for MainGame.java and Options.java when their respective buttons are clicked. When I click on Start, it launches the MainGame activity, but whenever I click on Options the app force closes. It's really weird because I'm doing essentially the same thing with both buttons. Here's the code for Title.java, let me know if you need to see anything else:
Code:
package com.freekyfrogy.treasure;
import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
import android.widget.Toast;
public class Title extends Activity implements OnClickListener {
Button buttonStart, buttonScores, buttonOptions, buttonExit;
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.title);
buttonStart = (Button) findViewById(R.id.buttonStart);
buttonStart.setOnClickListener(this);
buttonScores = (Button) findViewById(R.id.buttonScores);
buttonScores.setOnClickListener(this);
buttonOptions = (Button) findViewById(R.id.buttonOptions);
buttonOptions.setOnClickListener(this);
buttonExit = (Button) findViewById(R.id.buttonExit);
buttonExit.setOnClickListener(this);
}
public void onClick(View v) {
switch(v.getId()){
case R.id.buttonStart:
if(buttonStart.isPressed()){
startActivity(new Intent(getApplicationContext(),MainGame.class));
}
break;
case R.id.buttonScores:
if(buttonScores.isPressed()){
Toast.makeText(this, R.string.toastComingSoon, Toast.LENGTH_SHORT).show();
}
break;
case R.id.buttonOptions:
if(buttonOptions.isPressed()){
startActivity(new Intent(getApplicationContext(), Options.class));
}
break;
case R.id.buttonExit:
if(buttonExit.isPressed()){
finish();
}
break;
}
}
}

If i had to guess id say you didnt declare both activities in your manifest...
what does the debugger say is the problem?

I declared them both in the manifest, here's it's XML code:
Code:
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.freekyfrogy.treasure"
android:versionCode="1"
android:versionName="1.0">
<uses-sdk android:minSdkVersion="4" />
<application android:icon="@drawable/icon" android:label="@string/app_name" android:theme="@android:style/Theme.NoTitleBar">
<activity android:name="Title"
android:label="@string/app_name"
android:screenOrientation="portrait">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<activity android:name="MainGame"
android:screenOrientation="portrait">
</activity>
<activity android:name="Options"
android:screenOrientation="portrait">
</activity>
</application>
</manifest>
and the Error I'm getting is this:
Code:

Can you post your Options class? It looks to me like there may be something wrong in there.

Options class:
Code:
package com.freekyfrogy.treasure;
import android.app.Activity;
import android.os.Bundle;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
import android.widget.EditText;
import android.widget.Toast;
public class Options extends Activity implements OnClickListener {
int intX = 5;
int intY = 5;
EditText sizeX = (EditText) findViewById(R.id.editX);
EditText sizeY = (EditText) findViewById(R.id.editY);
Button setXY = (Button) findViewById(R.id.setXY);
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.options);
setXY.setOnClickListener(this);
}
public void onClick(View v) {
String strX = sizeX.getText().toString();
String strY = sizeY.getText().toString();
intX = Integer.parseInt(strX);
intY = Integer.parseInt(strY);
Toast.makeText(this, "this is a toast: "+ intX+ " "+ intY, Toast.LENGTH_SHORT).show();
}
}

Hi freekyfrogy,
you should declare there controls of in onCreate method of Options activity
EditText sizeX = (EditText) findViewById(R.id.editX);
EditText sizeY = (EditText) findViewById(R.id.editY);
Button setXY = (Button) findViewById(R.id.setXY);
your option activity code look like this:
package com.freekyfrogy.treasure;
import android.app.Activity;
import android.os.Bundle;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
import android.widget.EditText;
import android.widget.Toast;
public class Options extends Activity implements OnClickListener {
int intX = 5;
int intY = 5;
Button setXY = (Button) findViewById(R.id.setXY);
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.options);
EditText sizeX = (EditText) findViewById(R.id.editX);
EditText sizeY = (EditText) findViewById(R.id.editY);
setXY.setOnClickListener(this);
}
public void onClick(View v) {
String strX = sizeX.getText().toString();
String strY = sizeY.getText().toString();
intX = Integer.parseInt(strX);
intY = Integer.parseInt(strY);
Toast.makeText(this, "this is a toast: "+ intX+ " "+ intY, Toast.LENGTH_SHORT).show();
}
}

Oh I see now!!! Thanks so much, now it's not force closing haha

Click to expand...
Click to collapse
it tells you there, note that on line 239 you are asking an object (in this case "txtInfromacion") to execute one of it's methods, but the object is actually "null" so it throws the exception
disclaimer, I only looked at it for 10 seconds cause busy but I would think there is a 99.5% chance I'm correct
EDIT : ok looked at it another 5 seconds, you never assign anything to that TextView, like associating it with the view on screen ? eg. findViewById(R.id.someID)

[Q] what the correct way to use ShowcaseView?

when I try to use ShowcaseView I get error
Code:
@override
public void onActivityCreated(Bundle savedInstanceState) {
super.onActivityCreated(savedInstanceState);
final ImageButton saveButton = (ImageButton) view.findViewById(R.id.button_Save);
ViewTarget viewTarget = new ViewTarget(saveButton);
showcaseView = new ShowcaseView.Builder(getActivity())
.setTarget(viewTarget)
.setContentTitle("Reset Button")
.setContentText("This will erase all the data in the table except the line that in progress")
.build();
}
when I tried to do the same thing in my fragmentactivity and didn't work, but when I did the same thing but took a view that declared in the fragmentactivity and not in the fragment it worked.

String games_n;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
JSONObject json = new JSONObject();
try {
json.put("nick", "Johannes");
} catch (JSONException e) {
e.printStackTrace();
}
try {
Ion.with(getApplicationContext())
.load("http://example.com/post")
.setJsonObjectBody(json)
.asJsonObject()
.setCallback(new FutureCallback<JSONObject>() {
@Override
public void onCompleted(Exception f, JSONObject result) {
try {
games_n = result.optString("games_up");
} catch(Exception e) {
e.printStackTrace();
}
}
});
} catch (Exception IO) {
IO.getCause();
}
}
and that is the error i get:
Code:
error: cannot access TypeToken
class file for com.google.gson.reflect.TypeToken not found
I also make a picture of the wrong Part. Please help me thx.
https://github.com/koush/ion

I changed my code to:
Code:
JsonObject json = new JsonObject();
json.addProperty("nick", nick);
Ion.with(getApplicationContext())
.load("*****")
.setJsonObjectBody(json)
.asJsonObject()
.setCallback(new FutureCallback<JsonObject>() {
@Override
public void onCompleted(Exception e, JsonObject result) {
try {
JsonArray personen = result.getAsJsonArray("user");
for (int i = 0; i < personen.size(); i++) {
JsonObject user = personen.get(i).getAsJsonObject();
mTest.setText(user.get("games_up").getAsString());
}
} catch (Exception f) {
f.printStackTrace();
}
}
});
Now there is no Error in Android Studio, but the App stops when i execute it...

Any error logs? Or is the data too huge and needs to be ran on asynctask? You need to provide an example data from your server.

Ok, the php file is: (I make $nick to Johannes normaly i read this out of the POST Methode.
PHP:
<?php
/*$json = $_SERVER['HTTP_JSON'];
var_dump($json);
$data = json_decode($json);
var_dump($data);
$nick = $data->nick;*/
$nick = 'Johannes';
include 'db_connect.php';
$sql = mysql_query('SELECT * FROM user WHERE nick = "'.$nick.'"') or die(mysql_error());
while ($zeile = mysql_fetch_array($sql)) {
$id = $zeile["id"];
$games = $zeile["games"];
$games_up = $zeile["games_up"];
$coins = $zeile["coins"];
}
$user = array();
$user = NULL;
$user["games"] = $games;
$user["games_up"] = $games_up;
$user["coins"] = $coins;
echo json_encode(array('user'=>$user));
?>
That is an example for the JSON what is recieved:
HTML:
{"user":{"games":"","games_up":"14,","coins":"1500"}}
And that is the code I actually have, there is no error message in AndroidStudio and the App starts and Don't crash, but there is also no data...
Code:

Ion.with(getApplicationContext())

for (int i = 0; i < personen.size(); i++) {

JsonObject user = personen.get(i).getAsJsonObject();
mTest.setText(user.get("frage1").getAsString());
}
} catch (Exception f) {
f.printStackTrace();
}
}
});
}
}
This is the LOG:

[Q] Webview with a longonclicklistener help request!

Hello,
I am currently trying to have a webview that listens to a long click and loads a website once longclicked.
However, it crashes and i would love to find out why, or how to fix it
I do have to state that this crash Occurs on Samsung and LG hardware, but not on the Nexus 4 or the Emulator (Nexus 7)
Code:
package com.example.homehub;
import android.app.Activity;
import android.os.Bundle;
import android.view.KeyEvent;
import android.view.View;
import android.view.View.OnLongClickListener;
import android.view.Window;
import android.view.WindowManager;
import android.webkit.WebChromeClient;
import android.webkit.WebSettings;
import android.webkit.WebView;
import android.webkit.WebViewClient;
import android.widget.Toast;
public class MainActivity extends Activity {
WebView webView;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
// Go Fullscreen (Just in case)
requestWindowFeature(Window.FEATURE_NO_TITLE);
getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,
WindowManager.LayoutParams.FLAG_FULLSCREEN);
// Display the layout
setContentView(R.layout.activity_main);
// Define the Web View
webView = (WebView) findViewById(R.id.webView1);
// Setup
webView.getSettings().setCacheMode( WebSettings.LOAD_DEFAULT );
webView.setLongClickable(true);
// Handle Links internally
webView.setWebViewClient(new WebViewClient() { });
// Using Latest Chrome Client
webView.setWebChromeClient(new WebChromeClient());
// Browser Settings
webView.getSettings().setAllowFileAccess( true );
webView.getSettings().setAppCacheEnabled( true );
webView.getSettings().setJavaScriptEnabled( true );
// Go to Default URL
webView.loadUrl("http://google.com" );
// Long Click Listener
webView.setOnLongClickListener(new OnLongClickListener() {
@Override
public boolean onLongClick(View v) {
// Grab URL
String webUrl = webView.getUrl();
// Show the URL (This works)
Toast.makeText(getApplicationContext(), webUrl, Toast.LENGTH_SHORT).show();
// This request crashes
webView.loadUrl("http://www.yahoo.com");
return true;
}
});
}
// Back Button behaviour (Either browser back, or exit)
@Override
public boolean onKeyDown(int keyCode, KeyEvent event) {
WebView webView = (WebView) findViewById(R.id.webView1);
if(event.getAction() == KeyEvent.ACTION_DOWN){
switch(keyCode)
{
case KeyEvent.KEYCODE_BACK:
if(webView.canGoBack()){
webView.goBack();
}else{
finish();
}
return true;
}
}
return super.onKeyDown(keyCode, event);
}
}
And my Logcat:
