Android :: SensorEventListener - Syntax Error Says - Is Needed To Finish Statement
Nov 8, 2010
I am prepared to be humiliated on this, but I am not sure what is wrong. I am just playing around with Android development and am just making a simple application that will print out accelerometer to a TextView.
When creating the SensorEventListener, I get a syntax error (says ; is needed to finish statement)
Exact code in question:

I created a method and keep getting an error that I need to include a } at the end of my method. I put the } in and the error is still there! If I then delete that } the same error will pop up on a prior method; and that error wasn't there before. in other words, if i type the } on my most recent method then the error stays there and only there. if i delete it, it duplicates that error on my prior method.

I've run into the following issue:
Say I have an Animal class, which is parcelable, and I have a Dog class and a Cat class, which are subclasses of Animal and also implement Parcelable.
Say I have a service with the following AIDL interface:
sendAnimals(List<Animal> animals);
Now I'm calling this remote interface from some client application, passing it a List containing Cats and Dogs. What happens now is that android calls the Cat's and the Dog's writeToParcel() methods at the client side, but at the server side, the Animal's CREATOR is used, which calls Animal's readFromParcel() method. So the right data is sent from the client, but the wrong unmarshalling code is executed at the server.
I have tried to put this in the AIDL file:
sendAnimals(List<T extends Animal> animals);
This results in a syntax error from the aidl compiler though.
My current workaround is as follows: - In each specific Animal subtype's writeToParcel() method, I write the class name as a String into the Parcel as the first element. - In the Animal's CREATOR.createFromParcel() I read the first String out of the parcel, and based on that I create the appropriate type and call the appropriate readFromParcel() method.
I think this is kind of ugly though. I would expect the android framework to take care of this for me.
(My application is not actually dealing with animals, this is just to make it simpler to explain the issue)

I got problem with register. I use an if-else statement to check whether the user left any blank. If there is any blank, an error message will appear. The problem is, even with no blanks, all filled up, the error message still appears and thus prevents user from registering. I can't find any error.
Please help me spot my error.

I've posted a bigger chunk of the code below. You can see that initially QUOTE was procedural- coded in place. I'm trying to learn how to use declarative design so I want to do the same thing but by using resources. It seems like I need to access the string.xml thru the @R.id tag and identify QUOTE with that string value. But I don't know enough to negotiate this.

I am currently using sensors and I would like to know if I can slow down the sampling rate. Indeed, I register my listener with the constant "SensorManager.SENSOR_DELAY_UI" (is it the slowest one of the four constants mentionned in the documentation?) but the rate is still quite high. I would like to be able to define the time before giving the new value (For example, I would like to wait two seconds before update).

I have made a game with just one activity.. I just replace the views when I want to change screen. The game runs fine for a really long time inspite of what ever I do within the game.
But once I close the main game, by calling finish on the only activity in the application, and then when I start again, within the next 30 secs it crashes telling VM budget exceeded..
When I don't have a dispose() or a delete method in JAVA.. how the, am I supposed to remove the objects used in memory.. moreover I have android:launchMode="singleInstance" in my manifest

With this sample code, the activity is told to finish, but continues execution afterwards and displays the message. I'm trying to understand why this happens. The only fix I can think of is to place 'return' after finish.
public void someMethod() {
if( valueIsTrue) {
startActivity(new Intent(this, NewActivity.class));
CurrentActitivy.this.finish();
// return; // if uncommented, Toast doesn't show
}
Toast.maketext(this, "Some message", Toast.LENGTH_SHORT).show();}

This page in the Android documentation defines an element id as follows:
CODE:......
However this page defines it as:
CODE:..........
I thought I had a decent understanding of what was going on until I saw this second example. In the first case, you need the + character so that id 'label' is added to the R file, correct? In the second case, would the EditText's id not be added to the R file because it does not contain the + character?
Also, the second example does not include the android namespace on the id. Does having or not having the Android namespace affect whether that id will be added to the R file?

In my XML values strings code, I have a string with some text that I want to have only a few of the words in color. I also want to have a new line for some of the text.
I can do things like: < b> my bold text < /b> and that works (leading space added for this post).
I try to tag the text with color but no color shows up and there are no errors.
CODE:.............
I also try adding a new line - I've tried things like:
< LF> some text, space at beginning only for this post < /LF>
< CR> this didn't work either < /CR>
< p> some text, space at beginning only for this post < p>
But, no new paragraph / new line, carriage rtn happens.

I need to display a single list, ordered by date which contains different types of data, images, video and whatnot.
I guess you could have one separate table for each type and the use something like FULL OUTER JOIN (simulated as sqlite doesn't support it) and sort on date. But this would be complicated because I still need to have unique IDs across all tables.
Maybe having a master list which has ID and date, and then JOIN in the types tables? But how bad is the performance of this using sqlite? I really like to avoid having a super table which contains columns all the combined types could ever need.

How to make custom AVD skins by editing the layout file and associated .png files in the android-sdk-windowsplatformsandroid-nnnskins folders. The syntax of the layout file is simple and pretty self-explanatory but I'm curious about it ...
Is it meant to be hand-edited or is it generated from some tool or utility I should be using?
Any idea why they used this curly-brace syntax instead of something standard like XML?

I want to build an notepad-style application on android that will have syntax highlighting. But when I search around the web, I find the syntax highlighting can be done only through use of an awt class. How could I syntax highlight in maybe a custom EditText or TextView view? I know that the release of a syntax highlighter is sort of anticipated, so I want to add my syntax highlighter on the market.

Just getting started here. Working on an Android application, which needs to execute a google web search from within a ListView activity and display the results in that List View.
Such search would always be for the same "static" subject, such as "bowling alleys in Chicago...", so, the user will not be entering any search criteria. What is the proper way to accomplish this, please?

I have a strange issue. I am new to java/android but come from a programming background maybe I am just missing or doing something stupid with syntax here. I have a string variable called reportlength
String reportlength;
I then go: reportlength = intent.getExtras().getString("ReportLengt");
Now in my debug console for the variable reportlength it has it set as "d" (that is the correct value it should have)
At this point I have my if statement:

The problem I was having was that one of the TextViews would turn grey when it wasn't supposed to. I tried fixing it by always setting the text to black again, but that turned every single one of them grey.
Until I tried:

Don't know why the latter works when setting text grey, but there it is. I guess I'm just a little retarded.

How can I enable assert statement on Android? I have referred to a url: http://android.git.kernel.org/?p=platform/dalvik.git;a=blob_plain;f=d... and done what it said: adb shell setprop dalvik.vm.enableassertions all but nothing happen! The test code is: Log.v("assert 1","1"); assert false; Log.v("assert 2","2"); No matter what I did, "assert 2" will be printed, which means "assert false" does nothing! What should I do? BTW, I use eclipse as IDE.

I'm developing an application that tracks the user's current position and stores it into a SQLite database. Everything works fine, but now I have the problem when querying the database for a track with more than 1000 records it takes nearly 1.5 minutes. On my Desktop it just takes 1 second. I know it's a query with many subselects but I wasn't able to get the right result another way. In my opinion this belongs to the aggregate functions like avg() and sum().
