I have instantiated a fragment type that extends CameraFragment (and implements TabListener), and I am trying to call the autoFocus() from the the parent Activity. Calling autoFocus() from the fragment that extends CameraFragment works fine, but calling it from the parent Activity results in an NPE. I am listening for a onKeyDown() event in the main Activity, which works as expected as per the logcat. Here is my NPE trace:

I'm not sure what version of the code you are working on, but line 96 is a closing brace in the current CameraFragment.
The only way autoFocus() can crash with a NullPointerException is if cameraView is null, and the only way cameraView should be null is if onCreateView() has not yet been called. You need the fragment to be visible and fully created before you request auto-focus.

I just loaded my app created by cocos2dx-3.10 and when I open with it an AVD (again I haven't done any modifications to the app) the app crashes and gives the error: Unfortunately, libcocos2dx has crashed.
here is what I get in my android Monitor:

I'm trying to populate ListView with data from MySQL. I used this tutorial.
Here I want to get data only when rating is equal to 3. I try this, but it doesn't work. I don't really understand how JSON works. Probably I can't get the same value from the same column. Then, I try creating a new column with the same values like rating, but it doesn't work too. The emulator started, but then app crashed.
First attempt
try {
// convert json string to json array
JSONArray aJson = new JSONArray(sJson);
// create apps list
String rating = "3";
List<Application> apps = new ArrayList<Application>();
for(int i=0; i<aJson.length(); i++) {
JSONObject json = aJson.getJSONObject(i);
Application app = new Application();
String rating_of_app = json.getString("rating");
if ((rating_of_app).equals(rating)) {
app.setTitle(json.getString("app_title"));
app.setTotalDl(Long.parseLong(json.getString("total_dl")));
app.setRating(Integer.parseInt(json.getString("rating")));
app.setIcon(json.getString("icon"));}
// add the app to apps list
apps.add(app);
}
Second attempt with new column
try {
// convert json string to json array
JSONArray aJson = new JSONArray(sJson);
// create apps list
String rating = "3";
List<Application> apps = new ArrayList<Application>();
for(int i=0; i<aJson.length(); i++) {
JSONObject json = aJson.getJSONObject(i);
Application app = new Application();
String rating_of_app = json.getString("rating_for_if");
if ((rating_of_app).equals(rating)) {
app.setTitle(json.getString("app_title"));
app.setTotalDl(Long.parseLong(json.getString("total_dl")));
app.setRating(Integer.parseInt(json.getString("rating")));
app.setIcon(json.getString("icon"));}
// add the app to apps list
apps.add(app);
}
When I don´t put there if statement it works great but it is useless for me.
Here it is for the first Attempt:

So, I have an app which uses the Viewpager and swiping. I got 3 fragments which contains a listview, and a custom adapter to set the rows.
In each fragment, I have a method to call the asynctask and fetch the JSON. I run this method in the onActivityCreated.
When I start the app, everything is working fine, the progressdialog shows, and all the list's are being set with the correct data.
The problem is that i want to be able to refresh all the lists when click the refresh-button in the actionbar (to check for new tweets).
The only way I've been able to use the refreshbutton is when I use the onOptionsItemSelected() in the MainActivity.
So I'm thinking, I can just call the methods who then again calls the asynctask.
case R.id.menu_refresh:
MSFTHost host = new MSFTHost();
host.getTweets();
...
But when I click the button, the whole thing force closes:

the line 95 contains this:
listItems.add(new GetListItems(oneObject.getString("text"),oneObject.getString("created_at"),obj
.getString("profile_image_url"), obj
.getString("screen_name")));
I tried clearing listItems, but it didn't have any effect.
Any help please?
Edit:
If I was unclear, I want to get the JSON again and show in the list, just like on the first run.
My app runs fine on phone crashes on start up on tablets. It runs fine on my phone running 2.3.7 and my sister's phone running 4.0.3. But it crashes on my 10.1" tablet running 4.0.4. I tried it on a Nexus 7 AVD running 4.2 and it crashes there too.

Please help this is very frustrating. It used to run fine on tablets. Could it have something to do with the layouts?
try to put all your xml files in layout folder and no need to remove it from other if it already there.
If xml files are in folders like layout-sw600dp then the device will fail to load the specified xml file if screen width is less than 600dp. this is just example in your case it may be different
I have read your log, there is a bug on finding directory, have you use some directory method, to retrieve file from a particular location, tablet have internal storage instead of sd card might be problem in that.
But I can better understand if you post the code.
I try to use Google Contacts Data API on Android and more specifically the ContactsService class but the application crash as soon as I try to instantiate ContactsService class.
I do not have this problem with a normal Java application.
For example, below code is working fine
public class TestJava {
public static void main(String[] args) {
ContactsService myService = new ContactsService("TestApp");
System.out.println("OK");
}
}
However, below Android app crashes (I put the permission for Internet in the manifest)
public class TestAndroidActivity extends Activity {
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
ContactsService myService = new ContactsService("TestApp");
System.out.println("OK");
}
}
Does anyone know if Google Contacts Data API is working on Android?
Did I miss a permission in the manifest?
Thanks in advance.
Edit:
I used two projects in Eclipse to test above code: a Java project and an Android project.
Both projects share the same libraries and only the Android project is crashing.

I think you getting this type of error
Exception in thread "main" java.lang.NoClassDefFoundError: com/google/common/collect/Maps
Have you added google-collect-1.0-rc1.jar file? if not then I am sure you got the error, this is the dependent file.
you can download from this file from this site and download it and add in your project.
