and i can't get it .. can anyone help :)


From you code snippet for onCreate it seems that you have not called setContentView.
For this reason all calls for (X)findViewById(R.id.x); returns null and thus you are getting a Null Pointer Exception when you try to operate on the variables. [mainText is null since the view was not found].
Solution:
Call setContentView first and then initialize your variables and do the remaining stuff

please help.

It's looking for your ConnectPlugin class to be in the org.apache.cordova.facebook namespace. Check either what you have set for the package at the top of your ConnectPlugin.java file or under the org.apache.cordova.facebook namespace is there any file named ConnectPlugin.java.
The moto is that you have to kept a file under the org.apache.cordova.facebook namespace and name should be ConnectPlugin.java

Store/Save & Retrieve to/from SharedPreference Failure

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").

App Crashes after moving an image button! android

So my app Ive been developing lately is going great, and I just updated the image in the background of the app. Well the app was working right before I tweaked an image button to line up with this image I made. Right after I moved it, the app will no longer work and I have tried everything with no success. Here is the xml of the activity
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:background="#drawable/title_screen"
tools:context=".TitleScreen" >
<TextView
android:id="#+id/txtCoins"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentRight="true"
android:layout_alignParentTop="true"
android:layout_marginRight="18dp"
android:layout_marginTop="11dp"
android:text="000"
android:textAppearance="?android:attr/textAppearanceSmall"
android:textColor="#f3c50d"
android:textSize="12sp" />
<ImageButton
android:id="#+id/imageBtnPlay"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_below="#+id/txtCoins"
android:layout_centerHorizontal="true"
android:layout_marginTop="51dp"
android:background="#null"
android:src="#drawable/btn_play" />
</RelativeLayout>

android.widget.TextView cannot be cast to android.widget.ImageButton
You are casting to the wrong class in your activity change TextView to ImageButton somewhere in com.ChonBonStudios.Tidbits.TitleScreen class.

this is a common issue. Clean your project by selecting Project - Clean and it will work. And like gpasci said, check if you initialize your fields correctly

If I understand you correctly you just have switched the position of the TextView and the ImageButton in the layout, no code changes.
Try to simply clean the project and/or restart Eclipse. Sometimes I had a similar problem where the auto-generated Ids were just ouf of sync and that's the reason why a findViewById(R.id.imageBtnPlay) actually returns the TextView.
