setRetainInstance not working for ListFragment when using compatibiltiy library

由 做~自己de王妃 提交于 2019-12-05 10:25:06
I'm attempting to save a ListFragment subclass across an orientation change so I added setRetainInstance(true) to the end of my onCreate function. I added an onSaveInstanceState method to add all of it's data to a bundle, then added code into onActivityCreated to load that data back. Unfortunately, it wouldn't work. When I added some debugging messages with the help of Log.d I discovered that not only was onSaveInstanceState not being called, but onCreate was (which the documentation seems to say shouldn't happen when retainInstance is true). Neither onCreate nor onActivityCreated have bundles

I am heard that now Google start using ART, a new run-time for executing Android app and its come with Android 4.4 (in some devices).

I am heard that now Google start using ART, a new run-time for executing Android app and its come with Android 4.4 (in some devices) ART is not enabled by default on Android 4.4. It is enabled by default on the "L" Developer Preview. It probably will

Gradle conflict when using admob 15.0.0 with the lastest support library

由 家住魔仙堡 提交于 2019-12-04 04:25:32
I am using 'com.google.android.gms:play-services-ads:12.0.1'. and android support version 27.1.1. when I try to upgrade my ads library to the latest (15.0.0) I get an error saying that I must use the same version specification. See image below. Is there a way to use the latest version for both the supportLibraries and the play-services-ads ? Note that this problem does not exist when i use the play-services-ads version 12.0.1 You can try overriding the conflicted support library by adding the support library to your dependencies block: implementation 'com.android.support:customtabs:27.1.1'

Detecting thumb position in SeekBar prior to API version 16

由 蓝咒 提交于 2019-12-03 16:16:40
问题 Basically, I need to detect when the progress changes in the SeekBar and draw a text view on top of the thumb indicating the progress value. I do this by implementing a OnSeekBarChangeListener and on the public void onProgressChanged(SeekBar seekBar, int progress, boolean b) method, I call Rect thumbRect = seekBar.getThumb().getBounds(); to determine where the thumb is positioned. This works perfectly fine, but apparently getThumb() is only available in API level 16+ (Android 4.1), causing a

问题 I am trying to add some visual indication, that there are no more pages in the desired fling direction in the ViewPager. However I am struggling to find a place, where to put relevant code. I have tried extending ViewPager class with following code, but the Toast is not displaying ( ev.getOrientation() returns always 0). I have also tried the same with history points, but ev.getHistorySize() returns also 0. What am I missing? Class example: public class CustomViewPager extends ViewPager {

问题 Has anybody gotten the support library to render a grid layout correctly in Android 2?

Turn on hardware acceleration if available (such Android 3+) with Android APK 2.2

由 情到浓时终转凉″ 提交于 2019-12-03 07:06:28
问题 I developed a application for Android 3.0, and it's runs perfectly well, but the client insist on compatibility with 2.2 devices. Disabling hardware acceleration, using Android Compatibility Package, a NIO-backport support (For tasks and executors) and some reimplementation of View methods I was able to port my app for Android 2.2 and works really good, but if I run this apk into a newer device the performance is extremely slowly, so I want to know how to turn on hardware acceleration if
