Why can't I use Resources.getSystem() without a Runtime error?
public class BobDatabase extends SQLiteOpenHelper{
private static final String DATABASE_NAME = "bob.db";
private static final int DATABASE_VERSION = 1;
public static final String DEFAULT_PROFILE = "default_profile";
public BobDatabase(Context context)
{
super(context, DATABASE_NAME, null, DATABASE_VERSION);
}
@Override
public void onCreate(SQLiteDatabase database)
{
createProfileTable(database);
createTimeTable(database);
createEventTable(database);
createLocationTable(database);
}
/**
* Creates a table for Profile objects, executes the string create_profile_table_sql
* contained within strings.xml
* @param database
*/
public void createProfileTable(SQLiteDatabase database)
{
database.execSQL(Resources.getSystem().getString(R.string.create_profile_table_sql));
}}
I get this error
01-14 12:20:57.591: E/AndroidRuntime(1825): Caused by: android.content.res.Resources$NotFoundException: String resource ID #0x7f040003
The code that causes the error is the single line inside createProfileTable specifically, Resources.getSystem().getString(R.string.create_profile_table_sql) if I use a class variable to hold a Context and do context.getString(R.string.create_profile_table_sql) I don't get any errors but I don't want to do that because I want to avoid memory leaks and according to what I know this should work. Any idea what's happening?
According to Android documentation, Resources.getSystem()
only provides system-level resources, not application-level ones (like the resources inside your strings.xml file).
http://developer.android.com/reference/android/content/res/Resources.html#getSystem()
Try using the application's context if you really want to retrieve your strings this way, or take my suggestion in the comment to your question.
Using Resources.getSystem().getWhatEver() you can only access system-wide resources (you get the error because there is no system-wide resource with your ID). Since resource ID are not unique across applications you need to provide the application, when accessing a resource. In Android this is done using Context. So if you want to access some resource you need to use it like this
context.getResources().getString(myID);
Apart from that Brandon's comment is correct.
