there is a lot of thing you should change. have you changed the application ID in the gradle file??? it doesn't change automatically. have you updated the android manifest file?
try considering there...
I set the database path with a string like this: "/data/data/com.example. nabege/databases/". I changed it and solved the problem.Thank you for answering

I add more code as an answer.
I see from the stacktrace that you create DB helper in the activity constructor or field initializer possibly. In both cases activity isn't initialized yet (moreover you don't need to override activity constructor in the most cases). Move DB helper assignment inside the activity onCreate() method.

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").
I get this error when running my code, and I don't receive anything back from json

Basically I'm trying to use json, and the problem I'm having is with this line
HttpGet httpGet = new HttpGet(
"http://www.hotels-in-london-hotels.com/mytrolly/service.php?request={\"mode\":\"category\"}");
I've encoded the string, and I still get the exception
try {
url = "http://www.hotels-in-london-hotels.com/mytrolly/service.php?request={\"mode\":\"category\"}";
String encodedurl = URLEncoder.encode(url,"UTF-8");
Log.d("TEST", encodedurl);
} catch (UnsupportedEncodingException e) {
e.printStackTrace();
}
Any solutions?
You probably need to URL encode your parameter string. Try using URLEncoder
Character 68 is =, by the way.
Also, is there a problem beyond this warning (like you don't get desired result)? Note - it's not an error but warning.
The problem is the curly braces. I'd expect URLEncoder to take care of it, but you can also just manually replace them. '{' should be %7B and '}' should be "%7D".
This may helps you
String link="http://example.php?string1="+URLEncoder.encode(string1)+"&string2="+URLEncoder
.encode(string2)+"&string3="+URLEncoder.encode(string3)+"&string4="+URLEncoder.encode(string4)+"";
