Android :: Instruction Count In Nested Functions
Jul 22, 2010
I'm not sure whether I'm badly misusing InstructionCount or there is a bug, but let's assume the first one for now. The simplified situation is like that: I have a function (say, foo()) for which I want to track the number of instructions executed and the function itself calls another function (say, bar()), for which I also want to keep track of the number of instructions executed, something like: Code...

When I read the android source, I have found the macro nested classes. For example, the client in cameraservice, the autolock in mutex. Who can tell my why chooses the nested class to implement these functions.

I have a PreferenceScreen that is defined in XML that serves all the preferences for my application. This PreferenceScreen also has a child PreferenceScreen nested within it. My implementing class is called PreferencesActivity. I know I can open the main Preferences window via startActivity(new Intent(this, PreferencesActivity.class)); but how do I go about opening the child PreferenceScreen via an Intent?

I noticed a file was downloaded to my Samsung Galaxy S2 whilst the phone wasn't in use with the screen off and locked. I've attached a screenshot of the download to show the file name.
The same file was downloaded again approximately ten minutes later, again without instruction.I then ran AVG which didn't identify anything (the Settings Security Issue is having USB Debugging switched on)..I recently restored my applications using Titanium Back Up after flashing a new ROM.

Trying to have a ListView (scrollable list) of rows made of two TextViews. I have a list of items from a database that I want to populating into the LinearLayout->ListView->TextView but can't get to the id...
Layout somewhat like this instructional link, but have backed away from RelativeLayout and using LinearLayout to get it working. Not even worried about how it looks yet; just can't get it wired together yet.

Have two XML files (very abbreviated details below)
CODE:...........
I have an ArrayAdapter where I inflate the stuffView. My thinking and understanding of other examples is it's not inflated (this nested stuffView) until I purposely inflate it. That all works fine but when I do the findViewById it returns null and thus I can't setText().
epic Fail due to complete ignorance/newbieness on my part. Note: I've pored through what I can of Reto's book, especially a simliar example on Page 163 but fail fail fail...
Can some kind soul point me in the right direction?
Must I inflate this nested view? (Reto's example does). If so, what am I missing? I'm hoping someone can point me to a better example.
My code's probably too involved at this point to post and a bit proprietary.
CODE:........
A pojo called Thingy (not copying Thingy.java here - very simple)
The main class:
CODE:...........
So this code is in essence what I'm looking for help on; neutered the names to call it Thingy.... This sample isn't triggering the getView(). That's a secondary problem I have to sort out. More importantly, your help on the findViewById failure and if I've got the XML right would help a bunch.

Does anyone know where I can find the instruction manual for ClockworkMod Recovery? I want to know what each one of the options does, and when it should be used. If I use app2sd should I be wiping something extra when I install a new ROM? What does it do when it wipes the cache partition and dalvik?

I have a layout xml file with a linear layout. One of the children is again a ViewGroup Relative layout. In my java code i want to change the width of this child Viewgroup for my requirements. I tried this
ViewGroup childViewGroup = (LinearLayout)findViewById(childViewGroup);
LayoutParams l = childViewGroup.getLayoutParams();
l.width = 360;
childViewGroup .setLayoutParams(l);
I couldn't do this because findViewById(childViewGroup) doesn't fetch ViewGroups it does only for Views. Note: I cant define a whole new layout.xml for this minor requirement since it is huge layout file and might cause performance overhead. I wanted to just change the width of the child view group in my java activity code.

Recently, I have tried to know what would happen to an alive thread, when the device goes to sleep. I program a simple activity that will create and start a thread printing "HERE AM I" repeatedly through Log.d. I expect the thread would be stopped after I "echo standby > /sys/android_power/request_state." The screen is off, but the thread still keeps alive and prints out "HERE AM I." I don't know why the thread can't be stopped. I test this through emulator (1.5cupcake) and G1(1.1?), but the results are the same. Could anyone give me some suggestions or hints about this question?

I have a TabActivity which contains an Activity. When the tab for the activity is selected, if I press the Menu button, onPrepareOptionsMenu is called in the parent TabActivity, but not on the activity for the tab which was selected. The options menu for the activity in the tab isn't shown unless I click inside the tab, then I get calls to both (which is what I want). Is there any way to 'focus' the activity in the tab when the tab is selected?

I have looked all over the place. Here in the forums, online, user manuals, etc. What I am looking for: When I am texting, I see above the "A" key is an alt symbol that looks like an arrow pointing to the right with a verticle line. It appears to be an ALT-function of some sort. What is it? What does it do?

I read in the documentation for SQLite that there should be some core functions and aggregate functions available, but I can't seem to use them in my code.. Can anyone help? Here's the documentation ad: http://www.sqlite.org/lang_aggfunc.html http://www.sqlite.org/lang_corefunc.html There is for example the function count() but how do I use it? I have tried to use it as stated below, but none of the functions in the documentation is available that way (i.e when I type "db." the list that shows in Eclipse documentation doesn't include any of the functions from the SQLite doc except from execSQL):

Does anyone know of any app out there that can count how many sms have been sent to a particular number each month? my contract gives me around 70 sms to Europe and I don't want to go over this limit as it gets expensive!
There is only 1 European number I text so if I can count messages sent to just this number - In theory I will know how many I have left in my balance!

New to android..been using WM 6.1 sync with outlook obviously seemless. Need the same type of functionality but it doesn't have to be with outlook. Looking for options to use for business. Being a small company I can go anyway I want, don't have any restrictions other than need to sync all with phone, laptop and desktop. Beginning to travel more so contact, calendar and task must sync (notes and a Today front end would be nice). I have tried Dejaoffice but I end up with 2 sets of contacts and calendars (Samsung and Dejaoffice) not to mention that the UI is lame (had just as good 15 years ago with Instant Recall). Don't mind rooting the phone if needed. So what options exist in the open source world? Love my captivate phone but need to be able to do business to keep it. Anxious to hear how the rest of the Android world does it.

I've searched through the forums and tried a lot of notes apps, but I am yet to find one to my requirements:
- Should have widget support (I need to put some notes on my homescreen, not the note creation widget like 3bananas)
- Bluetooth sharing (or it stores the notes as .txt files on the SD card). Alternatively, it could sync with google in some way. If you know one that does these, please tell me. Else please tell me what app you're using, so that I can try it if I haven't already.
