Impossible to use ART on android emulator

由 烂漫一生 提交于 2019-12-22 18:49:23
问题 I just wanted to try ART of android 4.4 on my emulator. What I did was create an emulator with selecting device as "Nexus 7" and target as "Android 4.4" and RAM "512". Then I started emulator and it loaded. Then I went to Developer Options and selected runtime as ART. After that setting emulator started to reboot and kept on booting screen for a long time(around 1hr) and couldn't finish launching. Can anybody explain me the reason for this issue. 回答1: There is a bug in the emulator image. See

问题 Google added a new ART runtime with Android 4.4. How can I determine whether ART or Dalvik is the current runtime? 回答1: Update At least, as early as June 2014 Google has released an official documentation on how to correctly verify the current runtime in use: You can verify which runtime is in use by calling System.getProperty("java.vm.version"). If ART is in use, the property's value is "2.0.0" or higher. With that, now there is no need to go through reflection and simply check the

Does Android ART support runtime dynamic class loading just like Dalvik?

问题 Currently, it's possible to dynamically load .dex classfiles into Android's Dalvik VM. This could probably also be used for dynamic code generation at runtime. Is this still possible with the upcoming ART runtime? 回答1: It seems to work just like it did with Dalvik. Thanks to matiash for referencing the I/O 2014 talk! I've watched the video recording of it, and here is what the developers have to say on runtime code loading (taken from the transcript): [Question from the audience:] So I was

Does the Android ART runtime have the same method limit limitations as Dalvik?

问题 Does the Android ART runtime have the same method limit limitations as Dalvik? Currently, there's a limit of 64k methods in the primary dex file 回答1: The issue is not with the Dalvik runtime nor the DEX file format, but with the current set of Dalvik instructions. Specifically, the various method invocation methods, which look like this: invoke-kind {vC, vD, vE, vF, vG}, meth@BBBB B: method reference index (16 bits) You can reference a very large number of methods in a DEX file, but you can

Should developer consider any design objectives for ART (Android Runtime) with respect to DVM mode?

问题 I think, it might be bit early to ask this question. But need your thoughts on this. I read about ART mode (Android Runttime), which is as follows, "ART is a new Android runtime being introduced experimentally in the 4.4 release KitKat. This is a preview of work in progress in KitKat. It is available for the purpose of obtaining early developer and partner feedback." But also read that, Some apps might crash, if switch to ART mode. So, I want to know, whether do I need to consider any design

java.lang.StackOverflow Error for Android L preview running art

问题 Jumping straight to the topic, Android L introduces a ART as default runtime. I have a Sample Application, basically a document viewer. Most of the document viewing code including back buttons, Search,etc are written in C and the Android App uses JNI interface. I updated my code to make it build for Android L and it seems to open the document just fine. However, when pressing back button and closing the document, the Application seem to crash and the following backtrace is seen: I/DEBUG (

问题 I have recently stumbled upon this very strange bug that causes a crash while developing an app. Here is a logcat screenshot: And here is the code of the function in which supposedly it crashes: private static long Round(double d) { return Math.round(d * 1000.0); } What can be done here? Should I report this problem? EDIT: It might be relevant to an infinite recursion problem I had, because the problem seems to be gone now... 来源： https://stackoverflow.com/questions/22520107/android-art-failed
