从其他应用程序导航回我的应用程序时，我的Android应用程序崩溃

Question

I am working on android application, My application is crashing saying this message 'Unfortunately process "iTextSharpGeneric.ITextSharp" has stopped' when i am navigating form other application to my application. iTextSharpGeneric is my projoect name.

i found this excpetion in Adnroid device logging window:-

"java.lang.RunttimeException: Unable to instantiate activity ComponentInfo{com.iTextSharpGenericTest/iTextSharpGenericTest..TestActivity2}.java.lang.ClassNotFoundException"

Here is the scenari i am doing. In my application

ITextSharpGeneric--> Opening a pdf(using adobe reader)-> After Editing pdf In Adobe reader-> Selecting Share option-> Showing list of application-> I am selecting "iTextSharpGeneric" n the list of applications(to save that edited pdf details)-> "Application Crashes here"

I tried using the save OnSaveInstanceState() and OnRestoreInstanceState() for retaining the acitivity state. But still getting the same issue.

Here is my intent filters tags in AndroidManifest.xml

activity android:name="com.iTextSharpGenericTest.Activity2" android:label="iTextSharp"
intent-filter
action android:name="android.intent.action.MAIN" 
action android:name="android.intent.action.SEND" 
action android:name="android.intent.action.VIEW"
category android:name="android.intent.category.DEFAULT" 
category android:name="android.intent.category.BROWSABLE"       
data android:mimeType="application/pdf"             
intent-filter
activity  

What's wrong i am doing? Let me know you valueble suggesstions.

Here is the detailed log of exception, I just selected filter option"Android Runtime" in Android Device Logging Window.

Answer 1

"iTextSharpGenericTest..TestActivity2}" As you can see, you are actually passing your Intentfilter for you class wrong. There are 2 dots between iTextSharpGenericTest and TestActivity2 .

May be that's the case why it is not able to detect your TestActivity2 class and hence throwing that error java.lang.ClassNotFoundException .

Hope this helps.
