[Manish Pamnani]

Here's the error it gives while i try to compile the code:-

Information:Gradle tasks [:app:assembleDebug]
G:\SOURCE_CODE\DynamicUI\app\src\main\res\layout\activity_main.xml
Error:(17) error: mismatched tag.
Error:(17) mismatched tag.

and here's the event log for the app:-

14:52 * daemon started successfully

14:53 Executing tasks: [:app:assembleDebug]

Here is the original source code from where i got this tutorial:-

Android Fragment Transaction(One Activity|One container With Multiple Fragment)


or

https://github.com/hdpavan/FragmentTransaction

Here is my code for building a dynamic UI with fragments in android studio:-

Here is the screenshot of the android studio:-

Machine Enviornment:- Windows 10(64-bit)

I tried executing the app but it shows the error log and does't even open android emulator.

Android emulator:-Nexus 4 API 21

Can you post full activity_main code ? The code in Github is different with the code in screenshot_error.jpg

[Dave Tolls]

From that image you have a tag that is closed and then you add a close tag for it.
eg:
<myTag someAttr="foo"/>
</myTag>

Delete line 17:

</android.support.design.widget.AppBarLayout>

As Dave has already suggested, you've already closed it on line 15 with />

Yes it seems to have solved one of my problems and thanks for the reply!!
But can you look further into it and see more errors that i have got!!
I have posted the screenshot of activity_main.xml for further refrence!!
It would be nice to hear from you!!

Please don't post screenshots of text - post the actual text instead. That makes it much easier to read, quote and copy.

You'll need to post the errors and (as Tim says) paste the xml here in code tags.
It's not easy to trawl through a file manually looking for errors when there are tools (eg the compiler) that tell you what the errors are.

If the other error you're referring to is the AAPT2 exception, that is a plugin that is used by Android Studio when you're using Gradle 3.0. If you're having problems with it, you can always revert to the previous version.

I had to do so recently, myself, while tinkering with an older project.

Add:

android.enableAapt2=false

in your gradle.properties.

Although, truth be told, you may want to also dig in deeper to the problem at hand since that particular plugin is quite important to the new Android Studio environment.
You can read more about it here: About Android Plugin for Gradle 3.0.0
