Android icon is much smaller than other icons after using Android SDK tool?
See Documentation on Iconography for details. I assume that the SDK tool left some padding around your icon. Open the MDPI icon (which should be 48x48 px) and see if there is transparent pixels around. If yes, then you might want to enlarge the icon a bit to cover the whole 48x48 px.

Why have android:actionLayout and android:icon at the same time?
What are the conditions when the icon would show up? I can't rule out the possibility that the action bar will decide that there is not enough room for the actionLayout, but there is enough room for an action item, which would therefore show the icon. Also, with ActionBarSherlock, the icon is shown even in the overflow on Android 2.x devices, and so again if the actionLayout would be too large, the icon might get used. Also, if I used ifRoom|collapseActionView instead of just ifRoom, the icon would be used. That being said: My sample does not actually watch for this theoretical action item, should it appear, to do anything if the user clicks on it I am guessing at possible action bar behavior, as I have not tried any experiments to force the action bar to decide whether there is en

Import an Android Project from Eclipse to Android Studio and I have this error message "failed to find Build Tools revision 8.0.0"
Your build.gradle is trying to use Android SDK tools 8 which isn't installed on your machine. If you look at your build.gradle file you probably have this line buildToolsVersion "8". You want your build.gradle file to point to the Android SDK tools that you currently have installed (preferably the latest). Just open the Android SDK manager and see which tools you have installed and change the buildToolsVersion "8" to the right version.

Spinner usage on Android
You handle all of these logics in the adapter class, in your getView function the view that you return would have the required text alignment. Use a abase adapter and functions when item clicked store that position in your adapter class. and in your getview based on the position you can have any logic for alignment.

How to design a spinner in Android
You will have to create a custom layout for the spinner. I think the following XML might give you an idea. <?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="fill_parent" android:layout_height="wrap_content" android:padding="3dip"> <TextView android:id="@+id/number" android:padding="3dip" android:layout_marginTop="2dip" android:layout_marginLeft="5dip" android:layout_width="wrap_content" android:layout_height="wrap_content"/> <ImageView android:id="@+id/image" android:layout_width="wrap_content" android:layout_height="wrap_content"/> </LinearLayout>

Android: Spinner from ID Is Always Null
You should have this in your Fragment, not your Activity. Try something like Spinner mySpinner = (Spinner)getView().findViewById(R.id.mySpinner); in your Fragment. The reason is that it's your fragment that actually has the view, not the activity. EDIT based on your onCreate: Spinner mySpinner = (Spinner)myFragment.getView().findViewById(R.id.mySpinner);

Getting an enumerated value out of an Android Spinner
Due to type erasure, T will have no meaning at runtime, which is why the expression T.class is illegal. The workaround is to reference a Class<T> instance: public class EnumSpinnerListener<T extends Enum<T>> // note the correction here implements AdapterView.OnItemSelectedListener { private final Class<T> type; private String mValue = null; public EnumSpinnerListener(Class<T> type, AdapterView<?> adapterView) { this.type = type; adapterView.setOnItemSelectedListener(this); } public T getValue() { return Enum.valueOf(type, mValue); } }

Add a non-Android library project to an Android app in Eclipse
Method#1 seems so far the option to go for, but you need to study why you're getting that ClassNotFoundException - unpack the APK (since it's an archive), undex it and see why the library classes are not included. From experience, if you're working with Eclipse, I believe you're getting that exception because you didn't check the library as exported when you're adding it to Android project - after you've added it to build path, do the following: Project Props -> Build Path -> Order and Export, here make sure your library project is selected. There is a known issue/frustration about this ClassNotFoundException and the work-around is to select the export tab. I believe this article contains more details or this SO topic. When it comes to debugging the jar code, you need to include in the

Well it appears to me that you're using the wrong id's. You're getting a null pointer somewhere (I'm not sure where because there are no line numbers), but I see in your xml you have id's, footer and footer1, but in your code you are trying to find elements with id's footertab, and footer_tab. You should make these id's match.

Android 2.3.3 spinner auto sorting
I'm not sure what's going on. I've used spinners myself and never encountered that problem. Then again, I usually impose some sort of ordering myself, as I can't rely on the semi-random ordering of the database entries. I suggest you add a "order by _id asc" (or desc) to your request. This will force Sqlite to sort the data according to the sequence in which they were added to the database.

Spinner items not displayed in android app
To populate the Spinner items directly from XML you will need to supply them with an android:entries value: android:entries="@array/array_name" http://developer.android.com/reference/android/widget/AbsSpinner.html#attr_android:entries Reference to an array resource that will populate the Spinner. For static content, this is simpler than populating the Spinner programmatically. So in your case: <Spinner android:layout_width="wrap_content" android:layout_height="wrap_content" android:id="@+id/spinner" android:entries="@array/spinner" android:layout_below="@+id/textView" android:layout_alignParentRight="true" android:layout_above="@+id/textView3"/> And so on...

Android spinner to change setContentView
I don't know exactly what the problem is you are having but its pretty close. You just need to add the method @Override public void onItemSelected(AdapterView<?> arg0, View arg1, int arg2, long arg3) { TextView tv = (TextView)arg1; // get the TextView selected String text = tv.getText().toString(); if(text.equals("FirstText")){ // compare the text in the box setContentView(R.layout.lay1); //other code here }elseif(text.equals("FirstText")){ setContentView(R.layout.lay2); //other code here } } There are different ways of doing this such as getting the position (arg2) and comparing that to what's in your adapter but since I don't know how you are doing any of that, this is the easiest way to get you started.

disable the submit button if the spinner is empty? If there is no data to send then Yes. I wouldn't suggest doing it simply to solve the NPE. The better question is "Why is it null and should it be?" But then you also have a Spinner with no data so I think you need to investigate why that is and what it should actually be. and as I disable the submit button? I don't understand.

Android spinner layout... it's crazy?
That's because your emulator/device seems to be running on pre-ICS. The theme used is different there, and that's why there's a visual change. Try running on a post-ICS device/emulator and it will work well. (Or use ActionBarSherlock if you know how to work with libraries, and then set the application theme to "Theme.Sherlock.Light".
