All my urls have the same format (2 letter filenames, with .html extension). I want it to be a safe function, so if someone passes in an empty url it doesn't break.

• Unable to use getInt() but able to use getString() for a sqlite database

  - by mwrazam

  I am using a cursor to access a sqlite database I have in my app. I am having trouble using the .getInt() on my database. My database is pre-created, and I have a few cursors that perform queries to interface with the information. Several of the columns in one of the tables are set as INTEGER type. I realize that sqlite has no built in check to make sure columns are indeed INT. However, when retrieving the data, I can use the .getString() function without any issues, but calling .getInt() causes the app to crash. Below is the relevant code. If I am missing anything, please let me know, and I'll add it in. Any help is greatly appreciated. Thank you very much. Cursor: public Cursor getSkitStats(int module, int skit) { Cursor mCursor = myDataBase.rawQuery("SELECT * FROM score WHERE mod="+module+" AND skit="+skit+"", null); if (mCursor != null) { mCursor.moveToFirst(); } return mCursor; } and I am using a simple Toast call to output the result of the query: Toast.makeText(getApplicationContext(), scoreContent.getInt(0), Toast.LENGTH_SHORT).show(); The variable scoreContent is the cursor. And here is the crash output: 07-08 23:53:31.726: E/AndroidRuntime(15685): at android.app.ActivityThread.performLaunchActivity(ActivityThread.java:1659) 07-08 23:53:31.726: E/AndroidRuntime(15685): at android.app.ActivityThread.handleLaunchActivity(ActivityThread.java:1675) 07-08 23:53:31.726: E/AndroidRuntime(15685): at android.app.ActivityThread.access$1500(ActivityThread.java:121) 07-08 23:53:31.726: E/AndroidRuntime(15685): at android.app.ActivityThread$H.handleMessage(ActivityThread.java:943) 07-08 23:53:31.726: E/AndroidRuntime(15685): at android.os.Handler.dispatchMessage(Handler.java:99) 07-08 23:53:31.726: E/AndroidRuntime(15685): at android.os.Looper.loop(Looper.java:130) 07-08 23:53:31.726: E/AndroidRuntime(15685): at android.app.ActivityThread.main(ActivityThread.java:3701) 07-08 23:53:31.726: E/AndroidRuntime(15685): at java.lang.reflect.Method.invokeNative(Native Method) 07-08 23:53:31.726: E/AndroidRuntime(15685): at java.lang.reflect.Method.invoke(Method.java:507) 07-08 23:53:31.726: E/AndroidRuntime(15685): at com.android.internal.os.ZygoteInit$MethodAndArgsCaller.run(ZygoteInit.java:866) 07-08 23:53:31.726: E/AndroidRuntime(15685): at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:624) 07-08 23:53:31.726: E/AndroidRuntime(15685): at dalvik.system.NativeStart.main(Native Method) 07-08 23:53:31.726: E/AndroidRuntime(15685): Caused by: android.content.res.Resources$NotFoundException: String resource ID #0x2 07-08 23:53:31.726: E/AndroidRuntime(15685): at android.content.res.Resources.getText(Resources.java:205) 07-08 23:53:31.726: E/AndroidRuntime(15685): at android.widget.Toast.makeText(Toast.java:258) 07-08 23:53:31.726: E/AndroidRuntime(15685): at jp.atomicideas.ne.Summary.onCreate(Summary.java:90) 07-08 23:53:31.726: E/AndroidRuntime(15685): at android.app.Instrumentation.callActivityOnCreate(Instrumentation.java:1047) 07-08 23:53:31.726: E/AndroidRuntime(15685): at android.app.ActivityThread.performLaunchActivity(ActivityThread.java:1623) 07-08 23:53:31.726: E/AndroidRuntime(15685): ... 11 more

• what is this operator called and what is it used for <=>

  - by Scott

  I recently came across this magical operator when digging into Groovy: <= Groovy has really made me happy with elvis operators ?. and ?: which I use constantly now and very much wish were in Java. With this new operator, I have only found this reference. It seems to make comparators much easier. My question is how does it handle null values and how does it compare non Comparable object. Does this operator have a name, I couldn't find it Googling.

If I comment out a line of code that sets the images for the context menu entries then it stops throwing the exception. Any ideas?
