Totally stumped...zoom control issue

I'm developing an application that utilizes zooming in and out (for readability) and allows for swiping left and right to change pages.
Basically the flipping back and forth part works and zoom works. However, if I do any kind of zooming and then try to change a page the program crashes.
I've only tested this on the Epic 4G and on the G2 with the same problem.
Any help that can tell me what is going on or what I need to change would be greatly appreciated. (I tried to code out on the net to fix the HTC incredible having this kind of issue but the problem is still there)

Help with ViewPager and Fragments

Hi all!
I've been developing an app that uses various things from my college and centralizes them in one app. I've made the app with two tabs - one for current students and one for prospective students. I would like to add the functionality of swiping between the two activities, and I saw that to do that, I want to convert my currentStudents and prospectiveStudents activities into fragments.
I have a couple of questions.
First, I don't quite understand how to accomplish converting the activities into fragments.
Second, I don't quite understand how to implement the viewPager effect.
If anyone can assist me in doing this, that'd be great. I've read through a lot of guides, but those guides are written to reflect other apps and it's pretty confusing.
Here is my MainActivity:
Code:
package com.andrew.obu;
import android.app.TabActivity;
import android.content.Intent;
import android.graphics.Color;
import android.os.Bundle;
import android.widget.TabHost;
import android.widget.TabHost.OnTabChangeListener;
import android.widget.TabHost.TabSpec;
public class MainActivity extends TabActivity {
public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
TabHost tabHost = getTabHost();
TabSpec cstudents = tabHost.newTabSpec("Current Students");
cstudents.setIndicator("Students");
Intent cstudentsIntent = new Intent(this, CurrentStudents.class);
cstudents.setContent(cstudentsIntent);
TabSpec prospects = tabHost.newTabSpec("Prospectives");
prospects.setIndicator("Prospectives");
Intent prospectsIntent = new Intent(this, ProspectiveStudents.class);
prospects.setContent(prospectsIntent);
tabHost.addTab(cstudents);
tabHost.addTab(prospects);
tabHost.getTabWidget().getChildAt(0).setBackgroundColor(Color.BLACK);
tabHost.getTabWidget().getChildAt(1).setBackgroundColor(Color.BLACK);
tabHost.setOnTabChangedListener(new OnTabChangeListener() {
@Override
public void onTabChanged(String arg0) {
TabHost tabHost = getTabHost();
setTabColor(tabHost);
}
});
setTabColor(tabHost);
}
public void setTabColor(TabHost tabhost) {
for(int i=0;i<tabhost.getTabWidget().getChildCount();i++)
tabhost.getTabWidget().getChildAt(i).setBackgroundColor(Color.BLACK); //unselected
if(tabhost.getCurrentTab()==0)
tabhost.getTabWidget().getChildAt(tabhost.getCurrentTab()).setBackgroundColor(Color.rgb(34, 34, 34)); //1st tab selected
else
tabhost.getTabWidget().getChildAt(tabhost.getCurrentTab()).setBackgroundColor(Color.rgb(34, 34, 34)); //2nd tab selected

I recommend you to use ActionBarSherlock library: http://actionbarsherlock.com
Take a look at the samples and it will be easy to do what you ask for. At first, it may take a while to learn how to use this library, but you will not regret it since you will use it several times in the future for sure.
The coolest thing about this library is that it is compatible with older Android versions. I.e. The swipe effect will be available for Ice Cream users while for Froyo users will see two clickable tabs :good:

First of all, you can't swipe between activities. You can only swipe between fragments. Think of the activity as a container which holds your two fragments.
This is an example of a ListFragment:
Code:
public static class TitlesFragment extends ListFragment {
boolean mDualPane;
int mCurCheckPosition = 0;
@Override
public void onActivityCreated(Bundle savedInstanceState) {
super.onActivityCreated(savedInstanceState);
// Populate list with our static array of titles.
setListAdapter(new ArrayAdapter<String>(getActivity(),
android.R.layout.simple_list_item_activated_1, Shakespeare.TITLES));
// Check to see if we have a frame in which to embed the details
// fragment directly in the containing UI.
View detailsFrame = getActivity().findViewById(R.id.details);
mDualPane = detailsFrame != null && detailsFrame.getVisibility() == View.VISIBLE;
if (savedInstanceState != null) {
// Restore last state for checked position.
mCurCheckPosition = savedInstanceState.getInt("curChoice", 0);
}
if (mDualPane) {
// In dual-pane mode, the list view highlights the selected item.
getListView().setChoiceMode(ListView.CHOICE_MODE_SINGLE);
// Make sure our UI is in the correct state.
showDetails(mCurCheckPosition);
}
}
@Override
public void onSaveInstanceState(Bundle outState) {
super.onSaveInstanceState(outState);
outState.putInt("curChoice", mCurCheckPosition);
}
@Override
public void onListItemClick(ListView l, View v, int position, long id) {
showDetails(position);
}
/**
* Helper function to show the details of a selected item, either by
* displaying a fragment in-place in the current UI, or starting a
* whole new activity in which it is displayed.
*/
void showDetails(int index) {
mCurCheckPosition = index;
if (mDualPane) {
// We can display everything in-place with fragments, so update
// the list to highlight the selected item and show the data.
getListView().setItemChecked(index, true);
// Check what fragment is currently shown, replace if needed.
DetailsFragment details = (DetailsFragment)
getFragmentManager().findFragmentById(R.id.details);
if (details == null || details.getShownIndex() != index) {
// Make new fragment to show this selection.
details = DetailsFragment.newInstance(index);
// Execute a transaction, replacing any existing fragment
// with this one inside the frame.
FragmentTransaction ft = getFragmentManager().beginTransaction();
if (index == 0) {
ft.replace(R.id.details, details);
} else {
ft.replace(R.id.a_item, details);
}
ft.setTransition(FragmentTransaction.TRANSIT_FRAGMENT_FADE);
ft.commit();
}
} else {
// Otherwise we need to launch a new activity to display
// the dialog fragment with selected text.
Intent intent = new Intent();
intent.setClass(getActivity(), DetailsActivity.class);
intent.putExtra("index", index);
startActivity(intent);
}
}
}
I can't help you there because I've never worked with lists.
As for the swiping effect, build your project with a minimum SDK of 14 (ICS) and choose swipe-able tabs navigation. The ADT will do the job for you. Later, in order to maintain compatibility, use ABS library as patedit suggested.
Good luck

To implement a ViewPager, just add ViewPager to XML layout, and set a FragmentPageAdapter to it.
You must use support package from Android SDK and FragmentActivity instead of Activitiy.
You can examine source code of API Demos package to know more.

How to make the buttons in a fragment manipulate integer variables in seperate activi

This is a rudimentary android application that serves as an umpires strike/ball/out counter. There is a settings icon in the action bar of the MainActivity. When this icon is 'clicked on', a new Activity is started consisting of a PreferenceFragment, which consists of a checkboxpreference, and a Fragment that consists of 3 buttons. These buttons reset the stike_count, ball_count and total_outs_count to zero. I have spent a day on this and am having trouble figuring out how to manipulate integer variables in my MainActivity from button clicks in a seperate Activity's Fragment. Please point me in the right direction.

To modify anything in your activity from one of its child Fragments you would typically create an interface in the Fragment and have the activity implement that. That interface would either contain one method setting all three vars or multiple ones, one for each variable. To call the methods in the interface call getActivity() and typecast it to the interface.

Face Detection in Background Service

I am making an android app which requires to capture image using front camera using android service. Also we need to detect face in the image so obtained. But when calling the detectfaces() function, the app unfortuantely stops. I am posting the code for it here. Please help me find out where i am going wrong.
here is my code..!!!!

is there someone who could help me ?
thank you

After few months i still havent found a solution or idea.
anyone here has ?

Use a RSS parsing library
Use my AndroidWithoutStupid Java library. It is on GitHub. There is also an article about the usage on CodeProject.
Enclosure tag is usually used for mp3 files but it doesn't matter.
After getting the enclosure value using the MvNewsFeed class, you need to download it. Use MvAsyncDownload for that. Then, use BitmapFactory.decodeFile() or a similar method to display the image in an ImageView.
