I. What issues have been fixed

We found a bug related to instant execution (intant Run) in beta1 and fixed it immediately after discovery.

So try the Beta 2 version number, and we've overcome several serious problems with the early preview version number that will block the user from building.

1. Performance degradation:

Many users reported that the initial 2.0 version was built at a much slower pace than the 1.5 version, which is related to packing all of our dependencies into a single Dex file (because those are unlikely to be forth for immediate execution)
In some cases, however, Dex can slow down a lot because of the way it merges inside of Dex.

2. Libraries and plugins-based Dagger2 and some other annotation processors:

In the gradle2.x version number we have used the new "Incremental Java compilation" feature, but this feature does not work with the annotation processor, in the BETA2 version number, if a project through the "ANDROID-APT" plug-in using the annotation processor, we will voluntarily turn off the incremental compilation function. Manual processing will still fail (bug see: https://github.com/google/dagger/issues/298)

3. Fixed several other bugs that were executed on the fly:

For details, see the following tips for uninstalling your application.

4. Fixed several bug in SDK Manager:

Suppose you use a multi-system image to install an add-on that prevents the IDE from booting.

Two. Please note that the upgrade:

After upgrading to 2.0 beta, you should uninstall the debugged application from your phone/simulator. This will remove some of the bad app states that might affect instant execution in your phone.
We have fixed a bug in the state of write error. However, you cannot delete the app status that is already installed on your phone.

Three. Push program:

Assuming everything goes as planned, we want to push this version number to Beta channel within the next few days, but we would also like to thank you for your prompt feedback on the Canary channel, especially with regard to immediate execution. So we know Android Whether studio is really ready as a beta version number in your real-world application.

Thank you for testing our preview version number, please continue to quote US bug! (via Android studio-> menu bar, help-> Submit Feedback)
