Make sure your app has the Vibrate permission. The following line should be there in the manifest:
<uses-permission android:name="android.permission.VIBRATE"/>
I think you must be using an emulator. Just comment out the vibrate; somehow that's the cause of the issue.

how do i fix them?
every help will be apriciated.thank you for your kindness.
I had faced the same problem. I tried to fix it by a couple of ways, and both of them eventually worked!!
Go to onResume() at CaptureActivity.java. Comment the whole function except the line super.onResume(). Next, add the following lines into your activity:
#Override
public void onResume(){
super.onResume();
}
You could use the example from this link - http://khurramitdeveloper.blogspot.in/p/android-barcode-scan-using-zxing-library.html. It works for me without any hitch!
I'm trying to implement PagerSlidingTabStrip in my app. I did everything I'm supposed to do:
Added it to my XML:
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent" >
<android.support.v4.view.ViewPager
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/pager"
android:layout_width="match_parent"
android:layout_height="match_parent" />
<com.astuetz.PagerSlidingTabStrip
android:id="#+id/slidingTabs"
android:layout_width="match_parent"
android:layout_height="48dip" />
</RelativeLayout>
Created PagerSlidingTabStrip and tried to set ViewPager:
PagerSlidingTabStrip slidingTabStrip = (PagerSlidingTabStrip) findViewById(R.id.slidingTabs);
slidingTabStrip.setViewPager(vPager);
But when I run the app, it crashes and this is the logcat output:

The error isn't handled nicely in this library. If you look at the source of PagerAdapter you will see a method getPageTitle:
https://github.com/android/platform_frameworks_support/blob/master/v4/java/android/support/v4/view/PagerAdapter.java#L306-Lundefined
Notice that by default it returns null. This is why you are seeing a null pointer exception. The solution is to override this method in your implementation of PagerAdapter
#Override
public CharSequence getPageTitle(int position) {
// return the title of the tab
}
If you don't actually want a string title, and you want the tab to use a custom view, such as an image, then your PagerAdapter has to implement PagerSlidingTabStrip.TabCustomViewProvider and override getPageTabCustomView
#Override
public View getPageTabCustomView(int position) {
// return a custom view
}
EDIT: In order to use the custom tab view, you will need to use this fork:
https://github.com/astuetz/PagerSlidingTabStrip/pull/32
Caused by: java.lang.NullPointerException
at com.astuetz.PagerSlidingTabStrip.notifyDataSetChanged(PagerSlidingTabStrip.java:200)
You're throwing a NullPointerException on line 200 in PagerSlidingTabStrip.
This indicates that PagerAdapter.getPageTitle is returning null.
You should override your adapters getPageTitle method because it is returning null
#Override
public CharSequence getPageTitle(int position)
{
return tabTitles[position];
}
I want to set ActionbarOverlay feature from within my SherlockFragment class.
Can any one please tell me, how can I do this?
I've tried by adding line getSherlockActivity().requestWindowFeature(Window.FEATURE_ACTION_MODE_OVERLAY); in OnCreateView method.
But it gives me Error:

P.S. I can't set it from within Activity because I don't want overlay feature to be enabled for other Fragments in my Activity.
You Must Call before setContent called in your activity
getSherlockActivity().requestWindowFeature(Window.FEATURE_ACTION_MODE_OVERLAY);
put this before adding content view in your activity.
i hope it helps.
UPDATE
then extends first SherlockFragment in your Fragment
then put code in OnCreate method of Activity before calling setContentView method.
getSherlock().requestFeature(Window.FEATURE_ACTION_MODE_OVERLAY);
sorry my fault
check update again.

So problem shouldn't be tricky. Your problem is:

Question: What does it mean "Shared lib [name] already opened by CL.."? How to fix it?
P.S. I have tried other system libraries to load (e.g. android -/system/lib/libandroid.so, ..audioalsa, camera_client, etc) all of them loads without a problem.
I run a rooted Xperia phone with Android 4.0.3. All libraries are present on the phone.
