I am a newbie to Android App programming. I decompiled an APK and imported into Eclipse. I ran it on an Android emulator and I got the message below on Logcat. Can someone give me an idea where to start looking. The app works on the Android phone. Thanks.

I've been having so much problem with this Live Wallpaper.
I have read alot online about these, and I thought I understood and got them.
When I tried to apply them to this live wallpaper, everything has been going very rough.
I've spent all day and night :-(
Could you someone please help me out?
My goal is to store the new password from edittextpreference to the
Sharedpreference, and then retrieve this password to compared with the login
password to if they are matched.
For example,
I have 2 edittextpreferences:
1) is for create new password which will be saved to the SharedPreference
2) is for login password.
The users will be granted the access when the login password is matched with the
one in the SharedPreference.
Please help me out,
I would be appreciated for your help.
prefs.java Code:
#SuppressWarnings("deprecation")
#Override
protected void onDestroy() {
getPreferenceManager().getSharedPreferences()
.unregisterOnSharedPreferenceChangeListener(this);
super.onDestroy();
}
public void onSharedPreferenceChanged(SharedPreferences sharedPreferences,
String key) {
// TODO Auto-generated method stub
{
}
}
{
SharedPreferences mlogin_password = this.getSharedPreferences("data_storage", MODE_PRIVATE);
Editor login_password = mlogin_password.edit();
login_password.putString("login", "login_pw2");
login_password.commit();
SharedPreferences sp = PreferenceManager.getDefaultSharedPreferences(Context);
String s = sp.getString("login", null);
Sorry for 10000000 of error codes :-(

My goal is to store the new password from edittextpreference to the
Sharedpreference...
Not a good idea. You shouldn't store passwords on SharedPreferences
I would suggest using a different approach like storing the encrypted password on a server and then check what the user entered against it.
Please, also make sure you read the Android guide on SharedPreferences
Hi you are saving password on sharedPreference named 'data_storage' and retrieving from default sharedPreference thats why you are not getting saved password.Try to save and retrieve preference value from same sharedPreference.
Why don't you use getSharedPreferences for the key "data_storage" and not for getDefaultSharedPreferences, in other words, Context? I'm not really sure about it, but you should try.
The mechanism works as follows: you save the key under a string name "date_storage" then you retrieve they key. In both cases you need to get the SharedPreferences with the line:
SharedPreferences sp = PreferenceManager.getDefaultSharedPreferences(Context);
After that use the "sp.get()" methods to get the required value for the saved string key ("data_storage").
When I run my android application it gives an error "The application has stopped working,please try again". Please help me to solve this problem. i have created a method which gets called when the button gets clicked. When I include the code for calling another class in this method it shows the above error & when I remove that code it neither shows the error nor goes ahead when listview etc. gets clicked. Can you please check my code and help me please.
CODE:
public void myClickHandler(View view)
{
//Toast.makeText(this, "yesss",Toast.LENGTH_LONG).show();
setContentView(R.layout.screen1);
ListAdapter adapter = new ArrayAdapter<String>(this, android.R.layout.simple_list_item_1, city);
ListView FirstProjectActivity = (ListView) findViewById(R.id.mylist1);
FirstProjectActivity.setAdapter(adapter);
Intent myIntent = new Intent(FirstProjectActivity.this,
City.class);
FirstProjectActivity.this.startActivity(myIntent);
//startActivity(new Intent(FirstProjectActivity.this, City.class));
}
LOGCAT is as follows:

When you want to detect if you click on an item you need to implement the onItemClickedListener i will give you an example below like i would do it:
listView.setOnItemClickListener(new MyOnitemClickListener());
//no i make my own class that impelemnts the onitemclicklistener
public class MyOnitemClickListener implements OnItemClickListener {
private int position = 0;
public void onItemClick(AdapterView<?> parent, View view, int pos,
long lat) {
// clicked on parent.getid()
if (parent.getId() == R.id.listView) {
//do something
}
}
}
after a crash, try looking for the first couple of red lines the LOGCAT spews to you as they usually explain what happened.
the following line :
java.lang.NullPointerException
(in line 5) showed up on you log, it usually means your trying to use an uninitialized object.
refer to:
What is a NullPointerException, and how do I fix it?
I have a WebView in a TabView. The webView has a button. When the button is pressed a spinner is opened.
I am just loadng the webview with the URL. The action listener and spinner is triggered from the server side.
webview = (WebView) findViewById(R.id.webview);
....
....
webview.loadUrl(locationUrl);
My App is developed on Android 2.2. It is working fine in a device with OS 2.2 but crashing in 2.3.

Use getparent() to get the parent context. As this is a tab, everything is done in parent context.
I have a WebView in one of the tabs in TabView. The webView loads a specific url which contains a spinner. The action listener and spinner is triggered from the server side embedded in the url.
webview = (WebView) findViewById(R.id.webview);
....
....
webview.loadUrl(locationUrl);
My App is developed on Android 2.2. It is working fine in a device with OS 2.2 but When I click the Spinner my app is crashing in a device with OS 2.3.

I recently started programing and when I did a basic ImageView and TextView shown below.
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical" >
<TextView>
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="#string/texttry" />
</TextView>
<ImageView
android:id="#+id/joe"
android:src="#drawable/joe"
android:layout_width="wrap_content"
android:layout_height="wrap_content"/>
</LinearLayout>
The simulator crashed and the logcat gave this error:

I am also new to this website so I am sorry if I posted this wrong.
Also if it helps to know, when I take out ImageView the text works like a charm.
As I am sure you figured out in the end, the logs tell you where the problem is. Specifically this line (that I shortened so it fits):
11-24 11:09:20.958 .. Caused by.. #10: You must supply a layout_width attribute.
As you can see in the snippet below:
<TextView>
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="#string/texttry" />
</TextView>
You closed the <TextView\> element too early, before specifying any attributes. The one that log mentions is _layout_width_.
All you have to do to fix this 'issue' is remove the right shevron from the TextView element opening, like this:
<TextView
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="#string/texttry" />
</TextView>
Boom, done :)
PS: One teeny tiny detail though fill_parent is depreciated, you should use match_parent instead:
<TextView>
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="#string/texttry" />
</TextView>
I tried your code just now and seems to work when I take out the closing </TextView> tag:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical" >
<TextView
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="#string/texttry" />
<ImageView
android:id="#+id/joe"
android:src="#drawable/joe"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
/>
</LinearLayout>
