so far i had no bigger problems moving from ActionBarSherlock to ActionBarCompat. On my Nexus 4 it works pretty good. As i began to test on my older Nexus One running 2.3.6 i ran in an problem when i rotate the device. I request an Window feature to show the intermediate progress in the ActionBar:
#Override
protected void onCreate(final Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
requestWindowFeature(android.view.Window.FEATURE_PROGRESS);
requestWindowFeature(android.view.Window.FEATURE_INDETERMINATE_PROGRESS);
setupActionBar(getSupportActionBar());
}
This works pretty good on Jelly Bean.
On 2.3.6 is get this Stack Trace:

Call supportRequestWindowFeature(Window.FEATURE_...).
See http://android-developers.blogspot.com/2013/08/actionbarcompat-and-io-2013-app-source.html
Use supportRequestWindowFeature(WindowCompat.FEATURE_xxx)
i.e. You also need to use WindowCompat.FEATURE_xxx instead of Window.FEATURE_xxx for backward comptability.
For those, who don't call requestWindowFeature() method but still get the exception, try this workaround:
#Override
protected void onCreate(Bundle savedInstanceState) {
try {
super.onCreate(savedInstanceState);
} catch (Throwable e) {
//dummy workaround
}
setContentView(getLayoutResId());
see https://code.google.com/p/android/issues/detail?id=60841
Error log clearly says 'requestFeature() must be called before adding content'. So you have to call 'super.onCreate(savedInstanceState);' after 'requestWindowFeature' calls. And there is no need to call supportRequestWindowFeature(Window.FEATURE_...) as mentioned above. See the working code below.
#Override
public void onCreate(Bundle savedInstanceState) {
requestWindowFeature(Window.FEATURE_INDETERMINATE_PROGRESS);
requestWindowFeature(Window.FEATURE_PROGRESS);
super.onCreate(savedInstanceState);

I successfully built a map-fragment with android maps v2 and it works fine on my smartphone. now i plugged in my tablet and i get a NPE when i try to launch the map-activity. I am totally clueless at the moment; not even knowing what the source of the error may be. can anyone help? thx
OnCreate of map-activity:
FragmentManager myFragmentManager = getSupportFragmentManager();
SupportMapFragment mySupportMapFragment = (SupportMapFragment)myFragmentManager.findFragmentById(R.id.customer_map_fragment);
mMap = mySupportMapFragment.getMap();
mMap.setMyLocationEnabled(true); <-- line 103 with the NPE
mMap.setMapType(GoogleMap.MAP_TYPE_NORMAL);

You may learn about the reason via call to GooglePlayServicesUtil.isGooglePlayServicesAvailable.
It will return you an int value which you can compare with ConnectionResult constants.

foto is the path of my photo in gallery, i use it as button image, and it work, when user click on it i need to view that image in the gallery.
Use This Codes
Intent intent = new Intent();
intent.setAction(Intent.ACTION_VIEW);
intent.setDataAndType(Uri.parse("file://" + "/sdcard/test.jpg"), "image/*");
startActivity(intent);
You need to specify the correct path...

I tried my best to search this problem in google,someone give such advice:
enter link description here
but their methods did not work for me? I need your help!
Put <activity android:name=".QuestionsList"/> in your AndroidManifest.xml (Modify to suit where your activity is)
This is probably an initialization issue.
The java Smack reads at startup META-INF/smack-config.xml and loads the classes listed in there (thereby executing the static blocks in those classes). The Android asmack needs some work-arounds to get a correct initialization.
