[android-developers] (beginner question) variables reset when I change device orientation?
I am new to Android development. I am experimenting with making a simple
app that displays a number that increases by one when the Up button is
pressed and decreases by one when the Down button is pressed. It works
correctly, except when I rotate the device from landscape to portrait or
vice versa, the number is reset to 0. Here is the code:
package com.example.jz.counter;
import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
import android.widget.TextView;
public class MainActivity extends Activity implements View.OnClickListener
{
private int counter = 0;
private TextView OutputViewObject;
@Override
protected void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
OutputViewObject = (TextView)findViewById(R.id.outputView);
OutputViewObject.setText("" + counter);
final Button buttonUp = (Button)findViewById(R.id.up_button);
final Button buttonDown = (Button)findViewById(R.id.down_button);
buttonUp.setOnClickListener(this);
buttonDown.setOnClickListener(this);
}
@Override
public void onClick(View view)
{
switch (view.getId())
{
case R.id.up_button:
counter++;
OutputViewObject.setText("" + counter);
break;

counter--;

[android-developers] Placing files and folders inside Assets or resolving the path from within the code?
I created Assets folder by right click App > New > Folder > Assets Folder.

[android-developers] Question about android ICS touchscreen framework change.
Hi all,
Back in android2.3 there is such code in InputReader.cpp:
MultiTouchInputMapper::sync():
if (inPointer.absMTPressure <= 0) {
// Some devices send sync packets with X / Y but with
a 0 pressure to indicate
// a pointer going up. Drop this finger.
continue;
}
and
if (inPointer.absMTTouchMajor <= 0) {
// Some devices send sync packets with X / Y but with
a 0 touch major to indicate
// a pointer going up. Drop this finger.
continue;
}
so that means when you move your finger away from the screen,driver
send up a ABS_MT_TOUCH_MAJOR with absMTTouchMajor==0, this point is
dropped,through
MultiTouchInputMapper::sync()>TouchInputMapper::syncTouch>calculatePointerIds():
currentPointerCount == 0 and mCurrentTouch.idBits.clear();
then in dispatchTouches() currentIdBits <> lastIdBits and interpreted
as a UP movement.
BUT Android4.0 seems don't consider this ,in InputReader.cpp:
when driver send up ABS_MT_TOUCH_MAJOR:
MultiTouchMotionAccumulator::process();
case ABS_MT_TOUCH_MAJOR:
slot->mInUse = true;
slot->mAbsMTTouchMajor = rawEvent->value;
break;
mInUse is set to true no matter if rawEvent->value equals 0,and this
point is not dropped,in
MultiTouchInputMapper::syncTouch():
if (!inSlot->isInUse()) {
continue;
}
and mCurrentRawPointerData.markIdBit(id, isHovering); called.
Then in dispatchTouches(),because currentIdBits == lastIdBits,this
action is interpreted as a MOVE action,not UP!
Where am I wrong? Plz help,thanks in advance!

Re: [android-developers] Re: Android and OSGi/Apache Felix
I have looked at that, but the EZDroid community hasn't been updated since 2009 and there is practically no content on their site. This makes me think it is completely abandoned. They do link to some code which was presented at a conference a few years back: https://opensource.luminis.net/wiki/display/SITE/Apache+Felix+on+Androids The code is extremely basic though and it doesn't address any of my concerns. In their example projects, they create all views through code. They don't reference any Android resources, such as layout files. There is no discussion on what happens to the view created by the bundle if the bundle needs to be updated or removed. Also, there is the fact that it is impossible to add an activity or service to an application without modifying the Android manifest. -- You received this message because you are subscribed to the Google Groups "Android Developers" group.

[android-developers] Android and OSGi/Apache Felix
My company is working on an app that will be distributed outside of the Android Market. We plan to preinstall our app on devices and then loan the devices out to customers. We really want the ability to update our app completely automatically, without the customer having to do anything. I can see two options: 1) Use a custom ROM and give our app root permissions 2) Use OSGi Does anyone have experience using OSGi in an Android app? All of the discussions I've found are several years old. My main worries center around possible conflicts between the Android lifecycle and OSGi lifecycle. For example, would there be issues unloading a bundle that contained a layout and replacing it with a different layout? What happens if that layout is currently being used by an activity? I can see similar issues arising around Strings. Android is designed to update an application's components on app version changes; I just don't know if it's wise to use something like OSGi to bypass this process. I can see all sorts of potential for conflicts and memory leaks. What I'd really like to know is if anyone has successfully used OSGi to update Android specific things, like layout files and strings.

Re: [android-developers] why metaData in providerInfo is always null?
hmm, so I need to make explicit call to get ProviderInfo in the MyProvider:
context.getPackageManager().
resolveContentProvider(MyProvider.class.getName(),
PackageManager.GET_META_DATA);
even though Override function public void attachInfo(Context context,
ProviderInfo info) already has
a ProviderInfo info variable passed in.
I understand the limitation is because it is possible to have multiple
providers defined in
manifest file. when attachInfo() is called in base class, it has no
information of
the actual provider class name.
Can we improve the design like :
abstract class ContentProvider {
public void attachInfo(Context context) {
ProviderInfo info = context.getPackageManager().
resolveContentProvider(getClass().getName(), // <--- getClass()
will automatically resolve to the derived class name.
PackageManager.GET_META_DATA);
attachInfo(context, info);
}
public abstract void attachInfo(Context context, ProviderInfo info);
}
MyProvider extends ContentProvider {
public abstract void attachInfo(Context context, ProviderInfo info) {
// now info.metaData should have value, is not null.
assertNotNull(info.metaData);
}
}
android platform parses the manifest.xml file new instance of MyProvider
and then initializes it via attachInfo(...)
so the design will be more clean. please correct me if i am wrong.
regards!

[android-developers] Google maps api update
Any one have any information on whether or not there will be an update to the google maps api for android? Its woefully limited compared to the JavaScript version.

[android-developers] Drawing KML using the MapView API
Hi,
I'd like to draw KML on top of a MapView in my app. From searching
around, I've that it is possible to have the Google Maps app draw KML
by doing something like this:
Intent mapIntent = new Intent(Intent.ACTION_VIEW);
Uri uri1 = Uri.parse("geo:0,0?q=http://code.google.com/apis/kml/
documentation/KML_Samples.kml");
mapIntent.setData(uri1);
startActivity(Intent.createChooser(mapIntent, "Sample"));
This will start a separate activity, however, which isn't what I
want. Instead, I want to have a MapView in my app that has the KML in
it. Any ideas?
If there isn't a way to do this, it looks like I may have to write my
own Overlay?
Thanks,
Jesse

Depending on what parser you use, XML might need to do as much work as serialization - reflectively inspecting types and doing proper serialization lifecycle requires a lot of complex code.

Hmm. I'm not sure what the benefit of this is over #3. This basically
turns the result set on end, requiring extra complexity in the client
(looping over rows) without simplifying the server implementation.
It does get rid of the "single row" objection, I suppose. Come to

clear...

[android-developers] How to return non-table-oriented data from a content provider
I'm writing a content provider that returns data about game sessions. This data comes from an SQLite table. However, the client that consumes it will also want summary data: total wins, current/best winning streak, and so on. I'm not sure which approach to use. * Possible Approach 1: Do nothing, let the client calculate what it needs. The client could step through the whole table and calculate statistics itself. However, it's inefficient to send the entire database over the content provider link if the client only wants the summaries; this may also be prone to bugs because each client has to reimplement the summary calculations. * Possible Approach 2: Separate content URIs for summary data. The client could ask for a URI like content://myapp/summary/totalwins and get back a text/plain stream containing the number of wins. This seems like a big hassle to implement on both ends, though. Or it could ask for a URI like content://myapp/summary and get back an XML stream containing all the summary data, but this isn't much simpler. * Possible Approach 3: A phony table. The client could ask for a URI like content://myapp/summary and get back a cursor over a single row, with each summary value having its own column. This would not be an SQLite cursor but a custom in-memory cursor. It seems a little unnatural to use a table metaphor when there's always exactly one row, though. * Possible Approach 4: The extras bundle. Cursor has a getExtras() method that returns a bundle. The client could make a request for the main URI, content://myapp/sessions, and then just look at the extras bundle instead of reading any rows. However, there's no setExtras() method, so I'm stuck with whatever bundle object SQLite puts in there - and if it's Bundle.EMPTY, I'm out of luck. What do you recommend?

Also: would it still be possible to focus the check box using the trackball? I assumed TouchDelegates were only for touch, and so the trackball would only be able to move between list rows. In AlarmClock, the trackball can move horizontally between the clock view and check box inside a row, as well as moving vertically between rows.

Unfortunately I can't find any examples of TouchDelegate, and the class documentation is confusing. I gather that I need to pass the bounds of the check box (relative to its container) into the TouchDelegate constructor. Once I have a TouchDelegate instance, what do I do with it? I see a method called setTouchDelegate() - do I call that on the check box, the list row, or the view group that directly contains the check box?

[android-developers] Re: Trackball doesn't give me click events, but touch screen does
Romain,
Thanks for your response. I'm not sure if that approach will work,
though. My ListActivity's onListItemClick() method is called when I
click on an item with the trackball, but *not* when I touch it.
Perhaps the root problem is that my list rows have focusable items in
them (check boxes). The built-in Alarm Clock application has something
similar, though, and I can see from the source code that Alarm Clock
sets individual click listeners on the check boxes and the clock
views.
I'm trying to get the same behavior as Alarm Clock, where tapping on a
list row brings up an activity to edit the row, and the check box can
only be selected by tapping on the check box itself. I think that
precludes using multiple-choice mode for the list view, correct?

Pre-populating it and building the database file into your app, as the
other response suggested, is probably the best way to do it.
However, if you decide to populate the database when your app is first
run, you might still be able to speed it up by wrapping the whole
process inside an SQLite transaction. Otherwise, it creates a separate
transaction for each query, which is slow. That's according to the
SQLite Optimization FAQ (http://web.utk.edu/~jplyon/sqlite/
SQLite_optimization_FAQ.html), although that FAQ is out of date by now
so maybe it's no longer true.

[android-developers] Trackball doesn't give me click events, but touch screen does
I have a list activity that creates a header row above the data rows
from the adapter. I want to receive click events when the user selects
the header or a data row (but my data rows have check boxes in them,
so this part is tricky). When I use the touch screen, I get this
expected behavior:
1. Tapping on any row causes a click event and a dialog appears.
2. Long-pressing on a data row causes a context menu to appear.
3. Long-pressing on the header row does *not* show the context menu.
However, when I use the arrow keys (emulator) or trackball (G1), I get
this unexpected behavior:
1. Selecting any row fails to cause any click events, even though the
row's appearance changes like it's being clicked.
2. Long-pressing on the header row *does* show the context menu, which
I don't want.
3. Occasionally, it doesn't focus the correct row when I move up or
down (e.g. it skips from the header to the last data row).
What am I doing wrong?

[android-developers] Re: Pay app support?
If you absolutely must offer a trial, and the Market won't support it, you could offer a trial version of your app with some sort of kill switch (the application sets a flag and tells itself to stop working after 10 days) and a paid version that does not do this. It would not prevent a truly determined person from circumventing your terms, but given the nature of Android, why couldn't somebody just hack the Market app to ignore trial periods anyway?
