Sorry guys for the newbie questions. I'm new to android, was working to set some login system in new application. Everything worked fine (after a long while), i had a login button from the menu in the main page which was just an empty "hello world" default activity. Then I decided to remove the "hello world" text view, i tried to run it immediately and the application crashed with null exception. I was doing ctrl+z like crazy but the application keeps on crashing.
i understand absolutely nothing from the LogCat:

Maybe one of you guys will figure out where is the problem. Thank you very much.
here is something interesting:
W/WindowManager(59): java.lang.RuntimeException: Binary XML file line #25: You must supply a layout_height attribute. 1
you must specify layout_height in your layout views, its mandatory
I guess you're missing an atribute you should have defined to some View.
So, to the XML layout inflated (the one you inflate when setConentView(R.layout.this_one) somewhere on the onCreate() method, I guess) just check if is missing the android:layout_height="wrap_content". If so, please add it. This should resolve you issue.
Binary XML file line #25: You must supply a layout_height attribute.
Incase of runtime error, look for word Caused by: in your logcat.
This will help you to locate error easily.
Here in your case- look at logCat below...
00:10:18.292: E/AndroidRuntime(463): Caused by: java.lang.NullPointerException
10-24 00:10:18.292: E/AndroidRuntime(463): at android.content.ContextWrapper.getContentResolver(ContextWrapper.java:90)
10-24 00:10:18.292: E/AndroidRuntime(463): at com.application.mySoSpecialApplication.mySoSpecialApplicationApplication.(mySoSpecialApplicationApplication.java:14)
Ypu will find that run time error caused by getContentResolver at line 14 of (mySoSpecialApplicationApplication.java:14)
So here you located the error successfully.
After that look at the explanation by yugidroid
This will help you.

I have an activity that has a view pager and loads it's images from a JSON ( and so, several fragments ).
When I do some kind of external activity like start a phonecall or see a website ( via my aplication ), when this activity resumes it gives me a null pointer exception.

Is the any way that I can solve this?
Line 28: sUrl = activity.urlProfile.toString();
translation - on main activity I run the AsynkTask and I get this string sUrl . then on the fragment I cast the activity and get the string ( probably you would figure that by yourselves but it doesnt hurt to describe it all )
Either the fragment has lost the instance of that activity, so the field activity is null.
Or the the field inside the activity urlProfile is null.
Or you casted your activity into a wrong activity, usually you get the activity with getActivity() or you catch that from the parameters.
But the main problem is, that you try to call toString() on a null which causes the exception. Try to catch it with
if(activity != null && activity.urlProfile != null) {
sUrl = activity.urlProfile.toString();
} else {
// do something different when those objects are null
}
My app works good in portrait mode. when i use landscape mode and perform any activity it gets force close. The log says null pointer exception. I verified with the source all the information is passing good but getting force close.

Using the class DownloadManager, with this code:
DownloadManager.Request request = new DownloadManager.Request(Uri.parse("http://centraldemangas.com.br/forum/dbtech/vbshop/images/gifts/pidgey.gif"));
request.setAllowedNetworkTypes(Request.NETWORK_MOBILE | Request.NETWORK_WIFI);
request.setAllowedOverRoaming(false);
request.setTitle("pidgey.gif");
request.setDestinationInExternalPublicDir(Environment.DIRECTORY_DOWNLOADS,"pid.gif");
id = downloadManager.enqueue(request);
The exception is pointing to request.setDestinationInExternalPublicDir(Environment.DIRECTORY_DOWNLOADS,"pid.gif");
The problem is in
Unable to create directory: /mnt/sdcard/Download
Try this:
String name = Environment.getExternalStorageDirectory().getAbsolutePath();
name += "/YourDirectoryName/" ;
Do you have the proper permissions in your Manifest ?
See WRITE_EXTERNAL_STORAGE and READ_EXTERNAL_STORAGE permissions
I think you didn't give a sd card size when you crated the emulator.
Does anyone know the package name for Application Manager on android. I have a method that i want to allow the user to go directly from my app to the application manager:
public void goToApplicationManager(){
Intent startMain = this.getPackageManager().getLaunchIntentForPackage("com.android.settings.ManageApplications");
startActivity(startMain);
}
but that throws an error.. i can just do com.android.settings, and it will take the user to settings but i would like to take them specifically to the application manager. do i have the wrong package name?

Ive read that people say to fix the problem by cleaning the project but I have tried that twice and it didnt help. I also creted another project and copied the code, so I think it is something different. Any help is appreciated.
Line 36
txtBPM1.setText(120, TextView.BufferType.EDITABLE);
This error occurs when you access some controls or which is not present in your layout you pass on onCreate in you activity setContentView(R.layout.your_layout);. Just checkout all the id's , string's and other controls which you are using belongs to same layout or not
change 120 to be a string like so :
txtBPM1.setText(""+120, TextView.BufferType.EDITABLE);
(your error in MainActivity.java:line 36 (it is import generated R))
1.delete error line from import and use pop-up message on red R.id.**
2. close and reopen IDE
