java.lang.ClassNotFoundException on my android app and the Xml is find - android

I have met a problem follow:
07-20 18:10:52.755: ERROR/AndroidRuntime(3019): Caused by: java.lang.ClassNotFoundException: com.lok.camfly.CamFlyCtrlMain in loader dalvik.system.PathClassLoader[/mnt/asec/com.lok.camfly-2/pkg.apk]
I have search about this problem on google. So i check my xml and found that it is find. And the class name is match with the xml Activity name.

Please try and check if you have mentioned "package" entry in Manifest file. This could be the reason for the issue. Share the result.

java.lang.ClassNotFoundException in android studio

i am trying to add module and but its gvien error like this:
Caused by: java.lang.ClassNotFoundException: Didn't find class
"com.anghatechsolution.eww.datetimepicker.SlidingTabStrip" on path:
DexPathList[[zip file
"/data/app/com.anghatechsolution.eww.datetimepicker-1/base.apk"],nativeLibraryDirectories=[/vendor/lib,
/system/lib]]
can any one having idea about this.
This error means, that you are trying to access class, that currently doesn't exist.
Try to check the name of class, you accessing
You can solve it by setting the name attribute to your class like this:
[Activity(Name = "somepackage.custombuttonrenderer")]
public class CustomButtonRenderer: ButtonRenderer
{ }
An explanation is in my answer here: Why is my custom ButtonRenderer not working?

Unable to resolve AGPBI: {"kind":"error","text":"String types not allowed

I am new to android studio and building my first project.
The following error occurred:
AGPBI: {"kind":"error","text":"String types not allowed (at \u0027android:textColor\u0027 with value \u0027\u0027).","sources":[{"file":"/Users/AndroidStudioProjects/app/build/intermediates/exploded-aar/com.android.support/appcompat-v7/23.4.0/res/values/values.xml","position":{"startLine":1247,"startColumn":4,"startOffset":95714,"endColumn":61,"endOffset":95771}}],"original":"","tool":"AAPT"}
I have no idea what caused the error. I didn't edit anything in the values.xml file. I just tried to change the background of linearlayout after which this error occurred.
On line 1247 there is just a closing tag: < /style>
Can someone please help me?
Thank you
Here is the link to the xml file: https://github.com/mehulverma/values5way/blob/xml/values.xml
The problem resolved. I had specified the wrong colour in styles.xml file for a particular style. I removed the line and it worked. A rookie mistake I guess. Thanks for your help.

Android Runtime Exception: Unable to instantiate activity componentInfo?

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
