Android Development
Today, November 28 of 2011, we released a new update of Cupid-4-Stupid!
Some customers reported a bug that they were facing when trying to access content in Date Ideas and Panic Button sections.
This bug was produced after all the Android devices got updated.
After working around we found out what was the problem and solve it. Soon, we will release a more detail explanation of how we solve it.

We added BugSense after encounter an error with ACRA in which was crashing the application.
The code was failing when trying to initialize acra:
try{
ACRA.init(this); // The following line triggers the initialization of ACRA
}catch(RuntimeException e){
android.util.Log.e(TAG, 'ACRA init crashes: ' + e.getMessage());
e.printStackTrace();
}
Getting the following error:
10-30 22:02:37.908: WARN/System.err(2709): java.lang.NullPointerException 10-30 22:02:37.918: WARN/System.err(2709): at org.acra.ErrorReporter.init(ErrorReporter.java:363) 10-30 22:02:37.918: WARN/System.err(2709): at org.acra.ACRA.initAcra(ACRA.java:297) 10-30 22:02:37.918: WARN/System.err(2709): at org.acra.ACRA.init(ACRA.java:238) 10-30 22:02:37.918: WARN/System.err(2709): at com.hourglass.applications.MyApplication.onCreate(MyApplication.java:40) 10-30 22:02:37.918: WARN/System.err(2709): at android.app.Instrumentation.callApplicationOnCreate(Instrumentation.java:969) 10-30 22:02:37.928: WARN/System.err(2709): at android.app.ActivityThread.handleBindApplication(ActivityThread.java:4165) 10-30 22:02:37.928: WARN/System.err(2709): at android.app.ActivityThread.access$2900(ActivityThread.java:126) 10-30 22:02:37.928: WARN/System.err(2709): at android.app.ActivityThread$H.handleMessage(ActivityThread.java:1958) 10-30 22:02:37.928: WARN/System.err(2709): at android.os.Handler.dispatchMessage(Handler.java:99) 10-30 22:02:37.928: WARN/System.err(2709): at android.os.Looper.loop(Looper.java:123) 10-30 22:02:37.928: WARN/System.err(2709): at android.app.ActivityThread.main(ActivityThread.java:4568) 10-30 22:02:37.928: WARN/System.err(2709): at java.lang.reflect.Method.invokeNative(Native Method) 10-30 22:02:37.938: WARN/System.err(2709): at java.lang.reflect.Method.invoke(Method.java:521) 10-30 22:02:37.938: WARN/System.err(2709): at com.android.internal.os.ZygoteInit$MethodAndArgsCaller.run(ZygoteInit.java:860) 10-30 22:02:37.938: WARN/System.err(2709): at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:618) 10-30 22:02:37.938: WARN/System.err(2709): at dalvik.system.NativeStart.main(Native Method)
After spending long hours I found how that the error was produced when ErrorReporter class was not initialized.
For some reason ACRA 4.2.3 doesn’t pass the reference of the class (this) to ErrorReporter.
To fix it just implement the following:
ErrorReporter.getInstance().init(this); // include before ACRA.init(this);
Me and my friend, David Corrigan, spent more than three months working on our first Android application, Cupid-4-Stupid.
The idea of this project came from David and we both work together to make it true.
Our project allowed us to learn how application are build in Android plus how the android behaves.
We encounter many problems which allow us to learn a lot in a very short period of time.
After months of programming, researching sources, interviewing people, we put together an application with the purpose to help men with their relationship.
Cupid -4- Stupid is an application geared for men. This mobile application helps you to remember more than just her chest size – it keeps you out of the doghouse. It coaches you in your relationship and gives you a hand during those conflicting times. This is the perfect tool for those who are married or single. If you are a man, then this application is a must have.
Cupid’s little secrets (Shh… Keep them secret!)Help any man creatively and successfully pull off a perfect date.
The “Little” Black BookA separate discreet contact list to keep your valuable contact information
CalendarA sophisticated event reminding system such as:
Panic Button
The following code will hide the keyboard until the user press any user interface item such as a edit text to type in the information:
...
private void hideSoftKeyboard(){
Log.d(TAG, 'hideSoftKeyboard()');
getWindow().setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_STATE_ALWAYS_HIDDEN);
}
...
If you cross yourself with the following warning:
WARN/ActivityManager(78): Duplicate finish request for HistoryRecord
There is a chance that your application finish braking down.
This may occur when you write twice the method finish().
It seems that ActivityManager even do provide a warning, its die of a heart-attack when see the twins brothers of the method finish().
@Override
public void onItemClick(AdapterView<?> parent, View v, int position, long id) {
Log.d(TAG, 'onItemClick()');
...
finish();
...
finish();
}
So make sure you are not calling finish() once and later calling finish() again. Plus one finish() is more than enough.
