but if i run only one fragment if my viewpager activity it doesn't give me an error,

[Ulf Dittmer]

Where's the stack trace of the NPE? Or did you mean to say "IllegalArgumentException"?

MyFragment and MyFragment2 look similar; tell us in words how they are similar, and how they differ.

What is MainActivity for? you should never interfere with Android's lifecycle management by instantiating activities. Delete it.

[sam liya]

MyFragment and MyFragment2 are two pages of viewpager .It loads the two different pdf files.
withing each fragment i need to view different pdf files.

i used Mainactivity to open pdf files(Used Pdfviewer.jar).I put below code in MainActivity as it gives error when i put it on the Fragment.

public void open(byte[] data) {
		try {
		// pdfviewer create.
		SimpleDocumentReader viewer = SimpleReaderFactory.createSimpleViewer(this, m_listener); 
		// pdf data load.
		viewer.openData(data, data.length, "");
		
		} catch (Exception ex) {
			Log.e("KS", "error ", ex);
			ex.printStackTrace();
		} 
	}

SimpleReaderFactory.createSimpleViewer(this, m_listener)

here "this" requires Activity,when i put it inside fragment it gives error.

If you want to get help you really need to pay attention to what people ask of you.

[sam liya]

Currently there is no NPE ULF.It resolved now.now i am getting below exception only.But if i call only one fragment it doesn't give me any exception and it display the pdf file(WHether its fragment or fragment2).but if there is two fragment are there it gives me below exception

[Ulf Dittmer]

That stack trace looked identical to the one you posted before, so I have deleted it. Please don't post the same stuff more than once.

The reason I asked about the NPE is because you mentioned an NPE in the title of this topic. It is confusing if you then post the stack trace of some other exception, which apparently has nothing to do with your question. Please be more careful in the future.

I note that both fragments have different layouts, and that the exception seems to have to do with layouts. So post the layout XML of both fragment classes.

This also begs the question: why do you have two fragment classes, and why do they have different layouts?

i used two fragments as i need to pageviewer.i need to go other fragment whne user swipe.but i am getting above exception when i used 2nd fragment

[Ulf Dittmer]

i used two fragments as i need to pageviewer.i need to go other fragment whne user swipe.

I understand that you need multiple fragments, but my question was why you were using two fragment classes? The normal approach is to use the same class for all fragments. You want all fragments to be the same, just showing different PDFs, no? That would call for a single fragment class.

[sam liya]

ok ulf,i will try to use one fragment class.by the way can you please help to find the exception mentioned above

[sam liya]

i tried without pdf file,then pageviwer works fine and gives me page by page. below is the code.
