i am running a list-fragment program and at run-time i got the below error.
Error:
**02-09 09:03:40.213: ERROR/AndroidRuntime(572): java.lang.RuntimeException: Unable to instantiate activity ComponentInfo{ni.android.Fragment/ni.android.Fragment.Fragment}: java.lang.ClassNotFoundException: ni.android.Fragment.Fragment in loader dalvik.system.PathClassLoader[/data/app/ni.android.Fragment-1.apk]**
I don't know the reason.My program contains three classes- DetailsFragment.java, FragmentsTitles.java and Shakespear.java can any one help me out please....
At any time if you get an error stating Unable to instantiate activity ComponentInfo
That means your code has some error.
That error will be shown in log cat As Caused by:.........
1.Caused by: android.view.InflateException: Binary XML file line #13: Error inflating class fragment(This indicates that there is an error in xml and the activity has inflating problem.
By this you can know what is the error and if you rectify that error then your problem will be solved.
This blog will solve this issue.

Thanks
I had this error as well (beginner) and I noticed that I forgot to create the onCreate method in my activity class. Once I created that, the error went away.
If you have like this warning before error:
05-16 10:08:00.033: W/dalvikvm(1695): Unable to resolve superclass of Lmy/fragment/test/FragmentTestActivity; (7)
05-16 10:08:00.076: W/dalvikvm(1695): Link of class 'Lmy/fragment/test/FragmentTestActivity;' failed
Should export android-support-v4 to right to your app:
Configure Java Build Path -> Order And Export tab -> set checkbox android-support-v4.jar
(Maybe need to remove existing one firstly)
Make sure you are not only looking at error logcat ... as the error may be seen using verbose. But I agree with #parameshwar-s

I'm getting an unhandled exception when I try to access the hamburger menu on my Android simulator. The exception is:
Unhandled Exception: Android.Views.InflateException: Binary XML file line #14: android.support.v7.widget.AppCompatTextView cannot be cast to android.widget.ImageView occurred
It was working until very recently, but reverting all my code changes today doesn't fix the problem. I don't think the problem is with my code.
I don't know what I did to cause this, but I was playing around with different Navigation types when the problem came up. Couldn't find relevant information about the error online.
I´m implementing a android login button, when I start the app I get the following message error.
E/AndroidRuntime﹕ FATAL EXCEPTION: main
Process: com.droidsmile.opinions, PID: 31695
java.lang.RuntimeException: Unable to start activity ComponentInfo{com.droidsmile.opinions/com.droidsmile.opinions.MainActivity}: android.view.InflateException: Binary XML file line #13: Error inflating class com.facebook.login.widget.LoginButton
And other line:
Caused by: The SDK has not been initialized, make sure to call FacebookSdk.sdkInitialize() first.
Where can I call the method?
Thanks.
You have to use FacebookSdk.sdkInitialize(getApplicationContext()); before setContentView(R.layout.your_activity_layout); as documentation states out. In case you need a complete facebook login example, check this one here.

This problem appears to me when I try to open any xml file in eclipse:
Plug-in "com.android.ide.eclipse.adt" was unable to instantiate class "com.android.ide.eclipse.adt.internal.editors.common.CommonXmlEditor".
How can I solve this problem?
I have two custom components, one which I made quite recently, both in Android Studio. The earlier one worked. I followed the same procedure to make the new one but it throws runtime errors when I reach the activity screen during testing.
These are the exception messages, listed in order:
1. java.lang.RuntimeException: Unable to start activity ComponentInfo{com.sentient/com.mycompany.MyActivity}: android.view.InflateException: Binary XML file line #6: Error inflating class <unknown>
2. Caused by: android.view.InflateException: Binary XML file line #6: Error inflating class <unknown>
3. java.lang.reflect.InvocationTargetException
4. java.lang.NoClassDefFoundError: com.mycomponent.R$color
Error #4 shows the actual line itself that throws the error, it is part of the constructor of the component:
int color = res.getColor(R.color.progress_gray);
I checked the R file manually, and found the colors (progress_gray is defined in the colors.xml) to be present. I removed the line, and another line throws the error instead (which again depends on the R file to get information).
I have tried cleaning, changing build order in gradle, Make the component separately, and I still can't figure out where the mistake is. Any help is appreciated! Thanks.
can you post the xml file of the custom view?
Check if you have added to your main layout of the custom view xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:custom="http://schemas.android.com/apk/res-auto"
I got the solution. The applicationId in build.gradle and the package in the manifest were not matching. Once I changed it, it worked.
Strange though, I had thought that the reason the two were separated was so that they could be named differently. In any case, that was what got it working.
I am really getting desperate.
I have a working app - theoretically.
Tried to change the sdk version from 8 to 13.
Now when I start the app I get a Fatal exception, or rather a ClassNotFoundException for the very first activity started:
10-15 16:56:22.370: E/AndroidRuntime(862): java.lang.RuntimeException: Unable to instantiate activity ComponentInfo{com.example.pris/com.example.pris.MainActivity}: java.lang.ClassNotFoundException: Didn't find class "com.example.pris.MainActivity" on path: DexPathList[[zip file "/data/app/com.example.pris-1.apk"],nativeLibraryDirectories=[/data/app-lib/com.example.pris-1, /system/lib]]
Apparently there seems to be some mixup with paths, but I have not the slightes idea where, or how to fix this.
Please help!
clean rebuild and restart project.. btw do you have any additional libraries??
if so get rid of them
lol..
