ANDROID STUDIO FRAGMENT BREAKPOINT NOT WORKING ANDROID

Here's the sample app running on a Nexus S running Android 2.3.3 at 800x480: At this point, you can load the app on almost any device and run it.

ANDROID STUDIO FRAGMENT BREAKPOINT NOT WORKING UPDATE

Now update the manifest setting for minSdkVersion to 4 and targetSdkVersion to 10.

Change the call to the getFragmentManager() method to the getSupportFragmentManager() method.

Change the Activity to extend the FragmentActivity class.

For both TutListActivity and TutViewer Activity, follow these steps: Updating the two Activity classes is a bit more involved. Step 4: Switching to the Support Version of the Activity The final application will be compatible with 1.6 and we'll update or minSdkVersion in the manifest to show that. Why Android 2.3.3 instead of Android 1.6? Primarily this is to avoid changing out layout references to 'match_parent' with 'fill_parent'. Fixing the compile errors in TutListFragment and TutViewerFragment is trivial: simply open them and press ctrl-shift-o to switch around the import statements automatically to the appropriate APIs from the compatibility library instead of the Android 3.0 libraries. When you do this, you'll notice several compile errors. Instead, switch your project build target to API Level 10 (Android 2.3.3). We aren't using anything else from Android 3.0 (on purpose) so we no longer need to rely on the Android 3.0 SDK. The external library will provide the interface we need for the Fragment API use. Step 3: Updating the Project Build Target

ANDROID STUDIO FRAGMENT BREAKPOINT NOT WORKING CODE

You'll see how this is done if you download the code corresponding to this tutorial. In particular, you'll likely need to do this if you're using source control or otherwise sharing your application project. Note: You may need to copy the JAR into your project directory and reference it via 'Add JARs' button instead. Then choose 'Install selected' and follow the on-screen instructions, including possibly restarting Eclipse. To do this from within Eclipse, open the Android SDK and AVD Manager, click on Available packages, expand Android repository, and then choose Android Compatibility package, currently revision 1. Step 1: Downloading the Packageīefore you can use the Compatibility package, you must download it. You can download that code and build from there, though you will have some tasks you'll have to do unassisted, or you can download the code for this tutorial and follow along. This tutorial assumes you will start where our Fragment API tutorial left off. The final sample code that accompanies this tutorial is available for download as open-source from the Google code hosting. As of this writing, that covers 97% of all Android devices actively accessing the Android Market. This package provides support for the Fragment API as well as other key new features to devices as far back as Android 1.6.

ANDROID STUDIO FRAGMENT BREAKPOINT NOT WORKING HOW TO

When you were reading the last tutorial on how to use fragments, you were probably thinking, 'Wow, this is great, but I can't use any of this because I need to target more than just the Motorola Xoom, the only Android 3.0 device currently on the market.' Luckily for all of us developers, Google has released a library called the Android Compatibility package. Instead, use the NestedScrollView as outlined here.Android 3.0, or Honeycomb, came with some fundamental user interface changes, most notably in the form of the Fragment API. Nested ScrollViewsĪdding a ScrollView within another ScrollView can be difficult. In other cases, we want content to horizontally scroll in which case we need to use the HorizontalScrollView instead like this: Īnd now you have a horizontally scrolling view. Now the TextView will automatically scroll vertically. setMovementMethod ( new ScrollingMovementMethod ())

ANDROID STUDIO FRAGMENT BREAKPOINT NOT WORKING TV

Note that a TextView doesn't require a ScrollView and if you just need a scrolling TextView simply set the scrollbars property and apply the correct MovementMethod: Īnd then in the activity: TextView tv = ( TextView ) findViewById ( R.

Read this post by Romain Guy for a detailed look at this use case. In this case, you might need to apply the android:fillViewport property to 'true'. For example for a 'terms of service' where you can only accept once you've scrolled through all the content.

In certain situations, you want to position content beneath the end of the scrollable content area. Note that a ScrollView can only contain a single child element so if you need multiple things to be scrollable, you need to wrap that content into a layout as shown above. To make any content vertically scrollable, simply wrap that content in a ScrollView: When an app has layout content that might be longer than the height of the device and that content should be vertically scrollable, then we need to use a ScrollView.
