Re: [android-developers] Re: Activity lifecycle... still a mystery to me
2011/3/12 Indicator Veritatis mej1...@yahoo.com Actually, comparing with the text, I don't think it means just what is says. There is an asymmetry in the states, an asymmetry I believe is deliberate, if poorly explained: that between onPause and onResume: when you enter onPause, you may still be partially visible, but you lose input focus. But when you enter onResume you must have both full visibility and input focus. onResume() is called when you are becoming the top activity on the global activity stack. onPause() is called when you are going away from that state (prior to a different activity becoming the top). I'm not sure how this is asymmetrical? There are important implications about being the top activity -- for example you will have input focus over any other activities, your window will be on top of all other activities, etc. However there are some subtle aspects of this. In particular, being the top activity does *not* guarantee being input focus; input focus is based on windows, and there are a number of Android UI elements that are implemented as pure windows. This includes the lock screen, and notification shade. When one of these elements is shown, the top activity's window will lose input focus for that time. There are really three important pairs to the activity lifecycle: onCreate() / onDestroy() onStart() / onStop() onResume() / onPause() Any resources you create in the first of the pair should generally be released in the matching one. For example, if you use registerReceiver() in onCreate(), you should generally call unregisterReceiver() then in onDestroy(). These pairs represent symmetric major states of an activity: onCreate() is when it is first created, onDestroy() is when it is last being cleaned up; onStart() is when it is becoming visible, onStop() is when it is no longer going to be visible to the user. And we already talked about onResume() and onPause(). Finish would cause it too - your activity is about to not be visible (since it's going away). Cause what, too? It causes your activity to go through onPause() and onStop() (if needed) since it is no longer going to be visible to the user, and then onDestroy() since the activity instance is being destroyed. But what does front-most position really mean? That is what confuses many, not just the OP when reading the online documentation about the Activity lifecycle. My best attempt at reading the mind of the online doc's author is that front-most position means not only 1) being fully visible, most likely completely covering up all other Activities, but also 2) capturing input focus from all input devices: touch screen, keyboard... It really just means top of the activity stack, and since the windows created by activities are Z-ordered in the window manager based on that stack, its windows are on top, bringing along all of the repercussions of that both visually and for input focus. 3. How is onPause() - onResume() different than onStop() - onRestart()? What circumstances differentiate the flow? onStart / onResume depend on what happened before. In what way do they depend? Isn't it just a matter of onPause() - onResume() being as the documentation says, the foreground lifetime of the Activity has started? While onStop() - onRestart() is quite different? I would ignore onRestart(). It is useful for some semi-common situations we saw during app developer, where one wants to do some work when being started but not duplicate stuff that was already done in onCreate(). For the basics of the activity lifecycle, though, the 3 pairs are the important things to understand. I actually did work on a project where they somehow defeated the normal behavior of the home key -- and I hated that feature. I am sure most users feel the same way. Generally we consider this a security hole and fix this. The current platform has closed all the holes I know of; if there are new ways people have found to prevent the home key from working correctly, I would love to get a hold of the app to fix it. :) -- Dianne Hackborn Android framework engineer hack...@android.com Note: please don't send private questions to me, as I don't have time to provide private support, and so won't reply to such e-mails.

what it did instead. Nor have you given us enough info to duplicate
whatever the problem was.
This is not a quiz group. Based on the meager information you have
supplied we can only guess, which is usually a waste or your time and
ours.
That said, my guess is that you forgot: abortBroadcast() only works
with an ORDERED broadcast. You probably sent it a non ordered
broadcast, e.g., via Context.sendBroadcast().
Or you might have forgotten something else: you might have forgotten
that 'abortBroadcast' only sets a flag. You then have to wait for the
actual abort to happen.
Or are you not even seeing the Toast at all? In that case, there is
nothing wrong with abortBroadcast: you just don't even GET the
onReceive event. But that you will have to debug on your own.

Code is as follow

@Override
public void onReceive(Context context, Intent intent)
{
this.abortBroadcast();
Toast tag = Toast.makeText(context, Abort Broadcast!!!,
Toast.LENGTH_LONG);

tag.show();

[android-developers] Paint single Path object with Xfermode
Hi, I have one path object (for example recorded track). I'm drawing it on canvas. When I set semi-transparent color to paint object, whole path is colored like this. This is correct. Imagine that you was walking on some rectangle area from one side to another, few times you were on same place. And want to draw this path in same way you're drawing single lines, so you can see places where you were more then once darker then others (because line is draw there more then once). Anyway path object draw all areas with same color and because it's only one object, Xfermode PorterDuffXfermode(PorterDuff.Mode.DARKEN) have no effect on it. I hope you understand what I want. And I don't want to use only drawing single lines, because track width should be for example 100px. Nice example is here http://locus.asamm.cz/data/1300018457960.png. This is created with drawing single lines and I want to all path to be connected together but with darker places on place where I walk more then one. Do you have any tip for this or only to separate path into more pieces? thanks guys! -- You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] Re: how to write a view object into a parcelable class
thanks for your response!!
I will add more into the details, what scenario i am in.
I am trying to pick the Notification view from status bar and put into
another application.
Its our requirement that for our product we are planning to remove the
notification view from status bar and keep it in some other
application.
i did analysis on statusBarService, and found out that there is view
which is been inflated and statusBarservice is been called by
NotificationManager to update this view. It was quite very difficult
to decouple the logics between them.
-frameworks/base/services/java/com/android/server/status/
StatusBarService.java
private void makeStatusBarView(Context context) {
Resources res = context.getResources();
mRightIconSlots =
res.getStringArray(com.android.internal.R.array.status_bar_icon_order);
mRightIcons = new StatusBarIcon[mRightIconSlots.length];
**ExpandedView expanded** = (ExpandedView)View.inflate(context,
com.android.internal.R.layout.status_bar_expanded, null);
}
So i thought of passing this view instance ( i.e expanded ) to an
another application via aidl. and we can show the view, but updating
the view and those logics still remains same!!
It may not be the best approach, but still we wanted to try out and
see the pros and cons..!!
so my question was is there an way to convert view object to bytes and
pass them via parcel ? if so can you help me how to do that ?
Thanks,
Mani

[android-developers] RadioGroup listener won't listen when buttons are not direct children
I'm trying to make a RadioGroup with active games where there is a message
Your move! beside those games where it is your move. So, I modified my
RadioGroup to have LinearLayouts with horizontal orientation as immediate
children, then nest the RadioButtons inside those along with a TextView that
has the appropriate message where needed. Unfortunately, when I put the
LinearLayout between the RadioButtons and the RadioGroup in the hierarchy,
the RadioGroup OnClickListener() stopped working.
So, my question is how to get the RadioGroup to listen while still
dynamically generating a message for those games where it's your move.
Here's the code that generates the custom RadioGroup (a class
ResumeRadioGroup that extends RadioGroup) and which is setting the tags
correctly:
private void init(Context context) {
db = new ChessDataBaseAdapter(context);
db.open();
playerCursor = db.getActiveGamePlayers();
numPlayers = playerCursor.getCount();
Log.d(TAG, numPlayers + players found with active games);
final int playerNameCol =
playerCursor.getColumnIndex(PLAYER_NAME_COL);
final int playerIdCol =
playerCursor.getColumnIndex(PLAYER_ID_COL);
final int gameIdCol = playerCursor.getColumnIndex(GAME_ID_COL);
final int selfToMoveCol =
playerCursor.getColumnIndex(SELF_TO_MOVE_COL);
playerRadio = new RadioButton[numPlayers];
// new
LinearLayout container;
TextView moveText;
playerCursor.moveToFirst();
for (int i = 0; i numPlayers; ++i) {
container = new LinearLayout(context);
playerRadio[i] = new RadioButton(context);
playerRadio[i].setText(playerCursor.getString(playerNameCol));
Log.d(TAG, setTag() playerId: +
playerCursor.getInt(playerIdCol) + , gameId: +
playerCursor.getInt(gameIdCol));
playerRadio[i].setTag(new
PlayerAndGame(playerCursor.getInt(playerIdCol),
playerCursor.getInt(gameIdCol)));
moveText = new TextView(context);
moveText.setGravity(Gravity.RIGHT);
if (playerCursor.getInt(selfToMoveCol) == 1) {
moveText.setText(Your move!);
moveText.setTextColor(Color.parseColor(#ffddad65));
container.setBackgroundColor(Color.parseColor(#ff67656c));
}
container.setPadding(5, 0, 5, 0);
container.setOrientation(HORIZONTAL);
container.addView(playerRadio[i],
LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT);
container.addView(moveText, LayoutParams.FILL_PARENT,
LayoutParams.WRAP_CONTENT);
//*/
this.addView(container, LayoutParams.FILL_PARENT,
LayoutParams.WRAP_CONTENT);
playerCursor.moveToNext();
}
playerCursor.close();
db.close();
}
However, when I set up my listener for the RadioGroup as follows (in the
Activity that controls these views), nothing is happening when a button is
clicked:
private void init() {
selectedPlayer = -1;
selectedGame = -1;
continueButton = findViewById(R.id.continue_button);
gameRadioGroup = (RadioGroup) findViewById(R.id.resume_radio);
continueButton.setOnClickListener(this);
gameRadioGroup.setOnCheckedChangeListener(new
RadioGroup.OnCheckedChangeListener() {
@Override
public void onCheckedChanged(RadioGroup group, int
checkedId) {
selectedGame = ((PlayerAndGame)
findViewById(checkedId).getTag()).gameId();
selectedPlayer = ((PlayerAndGame)
findViewById(checkedId).getTag()).playerId();
}
});
}
That is, selectedPlayer and selectedGame just stay at -1 when a button is
clicked.
Any ideas how to fix this problem?

You need to have your RadioButtons be immediate children of your RadioGroup. Or, create your own RadioGroup with the smarts to look down the hierarchy for RadioButton children. Or, redesign your UI such that you do not need LinearLayouts in between the RadioGroup and the RadioButtons. In your case, you could simply use string concatenation to combine the radio button text with your message. Or, don't use RadioButtons.

[android-developers] Re: RadioGroup listener won't listen when buttons are not direct children
Thanks very much for the fast responses! I don't like the string concatention because the UI looks way better if I can make the message text a different color and size. Any suggestions on where to look to make my RadioGroup smart enough to look down the hierarchy or to drop the RadioGroup but keep the RadioButtons and manage their states by setting an onCheckedChangeListener? That would be my preferred solution, but I'm having trouble figuring out how to approach that.

[android-developers] Dynamic rows in a TableLayout
Hi I 'm trying to add dynamic rows to a table layout I current have an image button (to add) and then it runs the code TextView txt02 = new TextView(row.getContext()); txt02.setId(102000 + table.getChildCount() + 1); txt02.setTextSize(TypedValue.COMPLEX_UNIT_PT, 10); txt02.setText(Description); txt02.setWidth(400); txt02.setHeight(20); row.addView(txt02); to add all the elements in this new row and then adds the row to the table. I would prefer to us the layout new_row.xml which has TableRow xmlns:android=http://schemas.android.com/apk/res/android; android:id=@+id/invNewRow android:layout_margin=2dp EditText android:id=@+id/invName android:text=Description style=@style/EditFont.Black android:layout_margin=2dp android:background=#FF android:layout_width=400dp android:layout_height=20dp / /TableRow I need to interact with each of the elements, so the first element might be a spinner to select and item code and then fill in the Description based on the spinner value etc...

You will need something that implements OnCheckedChangeListener, might
as well be your activity.
Also something to store the currently selected radio button (e.g.
private CompoundButton mCurrentButton).
Then in onCreate, find all the radio buttons, and call
button.setOnCheckedChangeListener for each.
Finally, in the thing that implements OnCheckedChangeListener,
something like this:
@Override
public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {
if (isChecked mCurrentButton != button) {
mCurrentButton .setChecked(false);
mCurrentButton = button;
}
}
With the above you don't need a RadioGroup, and the currently selected
option is always in mCurrentButton.

[android-developers] Making Views the Same Width
Is there a standard idiom for an Activity to enforce that two of it's child views have the same width in cases where a LinearLayout won't do it (like two horizontally adjacent buttons)? I assume it would involve something like overriding onDraw, but perhaps there is another entry point that is more appropriate.

[android-developers] ANN: Mock Objects on Android with Borachio
One of my biggest frustrations with writing code for Android has been the fact that none of the current Java mocking frameworks work on Android’s Dalvik VM. I recently released Borachio a native Scala mocking framework which does work on Android. Because Borachio is written in Scala, you’ll need to write your tests in Scala. But it can be used to test code written in Java. There's a description of how to use Borachio on Android on my blog: http://www.paulbutcher.com/2011/03/mock-objects-on-android-with-borachio-part-1/ http://www.paulbutcher.com/2011/03/mock-objects-on-android-with-borachio-part-2/ http://www.paulbutcher.com/2011/03/mock-objects-on-android-with-borachio-part-3/ I'd be very interested in any feedback! -- paul.butcher-msgCount++ Snetterton, Castle Combe, Cadwell Park...

[android-developers] Re: Global Variables
public static final apiKey = xxx;
now you can access it as:
String key = globalVars.apiKey;
However, not that this is not a variable, its a constant.
According to convention, it should be in upper case:
public static final API_KEY = xxx;

this is just my lack of knowledge on Java here. I was hoping it was
something like globalVars.getApiKey(), but that doesn't seem to work.

[android-developers] Re: ANR keyDispatchingTimedOut on android/com.android.internal.app.RingtonePickerActivity
I've seen these when running monkey when with the version of my app that has market licensing. Monkey would stop and dump reporting a crash but nothing is showing on the emulator and the app continues to run just fine. What I've read but not dug into yet is that the thread needs to be set up differently than the code in the market licensing does. Apparently they need to update it. Much more rarely I've seen it without any licensing but ignored it since it didn't pop up a crash dialog and the app continued to run fine. In the dump above the stack trace appears to be connected to the app code (unlike mine case) and look up what is happening at that point in your code if you find anything at all.

It is just the stacks of all of the Dalvik threads in your process at the time of the ANR.

Re: [android-developers] Re: Making Views the Same Width
You'll need to write your own layout manager that implements the layout algorithm you want. Writing a layout manager to accomplish a specific layout is not hard; the ones that are built into the platform look complicated because they try to handle anything reasonable you throw at them and tend to have lots of options. Doing this is not related to an Activity at all. On Sun, Mar 13, 2011 at 2:47 PM, Jay johnabloodwor...@gmail.com wrote: Thanks. I should have been more clear.

[android-developers] peculiar or undocumented behavior of ExifInterface?
I have been trying to use ExifInterface and am either doing something very wrong or my subject line is correct. If I run the following code ExifInterface hoohaa; hoohaa = new ExifInterface(filename); hoohaa.saveAttributes(); on a photograph taken by the standard android Camera application, a whole bunch of exif fields previously defined have disappeared (as evidenced by inspection with Exiftool (Phil Harvey) and other such programs). I find this very peculiar. On a much less important issue, if a photograph with a JPEG comment (NOT an exif UserComment) is the object of ExifInterface hoohaa; hoohaa = new ExifInterface(filename); String haahoo=hoohaa.getAttribute(UserComment); the JPEG comment will be returned as if it were an exif UserComment. I find this friendly in a way, but unwarranted and undocumented... Have I got this all wrong?

[android-developers] Creating SQLite DB
All, I am trying to create an SQLite DB but for some reason it's not working. My logic performs the following. db.openDatabase(GlobalVars.DATABASE_NAME, null, 0); This simply tries to open my DB. If the DB doesn't exist it will throw an exception, which I can check, but I would suspect that if the DB can't be opened it doesn't exist, therefore my assumption then is that this is a new install of my app and I need to create my DB. So, in my exception I am doing the following: db.openOrCreateDatabase(GlobalVars.DATABASE_NAME, null); I'd expect the above command to create the database regardless, but it isn't. The exception I am getting for both of the above commands is: *unable to open database file. *I am surprised am I getting this in the second exception as I would expect it to create the DB.

[android-developers] RSSI values
Hi, I trying to make a wifi meter and to get wifi signal strength I'm using the following code: WifiManager wifi = (WifiManager) context.getSystemService(Context.WIFI_SERVICE); int rssi = wifi.getConnectionInfo().getRssi(); I get values between -40 and -90 when connection is established and -248 when it's not and I'm using a Samsung Galaxy S for testing. Is -40 and -90 the max and min values for RSSI or will it change in different terminals? Is -248 also a constant? Are they available on the API?

Re: [android-developers] Renderscript vs WebGL
It is also worth pointing out that it may be difficult to be able to contribute in this kind of area. The engineers responsible for different parts of the system also have obligations they need to deliver for upcoming releases; if someone wants to make a contribution that deeply impacts their code and will require a fair amount of time to review and integrate then they may need to prioritize it accordingly. Not to mention needing to account for its impact on QA, documentation, and other parts of the release process. Anyway, android-contrib is the correct place for this kind of discussion.

[android-developers] NullPointerException onCreate for a small number of users
I have a relatively successful app in the android market that a very
small amount of users experience force close on start up of the app.
It is not happening on a specific device, im not sure if it's
something these users have installed that is interfering with the app.
I've tried to troubleshoot with a few users having the problem, but
cannot get to the bottom of it.
it happens on both rooted and non-rooted phones
I keep getting a NullPointerException for a small number of users who
use a variety of phones that normally work.
anyone know what may be causing this, or how to get around this? I
can't figure this one out and cannot replicate the problem, please
help.

not spam the board)

[android-developers] Re: NullPointerException onCreate for a small number of users
Do you have howtoplay_button defined in your layout-port/main.xml and
not in your layout-land/main.xml ?
(Or in general if you have multiple main.xml files, for different
screen sizes or whatever, and forgot to update one of them, this can
happen)

[android-developers] Re: NullPointerException onCreate for a small number of users
Well its pretty clear from your stack trace and code that sometimes
the howtoplayButton is null.
If its working most of the time, are you sure you don't have multiple
layouts of the same view?
Double check that *all* versions of R.layout.main in your app contain
the button.
in fact, search for howtoplayButton in main.xml and see what you
come up with... every one will need that button, or you need to handle
cases when it doesn't.

Re: [android-developers] Reasoning behind disabling certain ProGuard optimizations?
When using Proguard I was getting a VerifyError on SDK 3 when trying to
access the Version.SDK_INT field.
With proguard disabled, everything worked fine because I was using the
standard approach of using a wrapper class to prevent VerifyErrors:
public static int getSdkInt() {
int sdkInt = getSdkIntSafely(); if (sdkInt 4) { return sdkInt; } else {
return VersionSdkIntWrapperForDonut.getValue(); } } private static int
getSdkIntSafely() { try { return Integer.parseInt(VERSION.SDK); } catch
(Throwable t) { return -1; } }
private static class VersionSdkIntWrapperForDonut {
private static int getValue() {
return VERSION.SDK_INT;
}
}
However, it appears that (using the default Android Proguard config), the
wrapper class was being optimized in such a way that this technique no
longer worked.
My current workaround is to specify -dontoptimize which works fine.
Is there a more specific flag to use?
