Android Question

Unable to instantiate application com.android.tools.fd.runtime.BootstrapApplication ?Android

I updated my Android Studio to version 2.0. But I had a problem, I don't know why?

The important error info:


Unable to instantiate application com.android.tools.fd.runtime.BootstrapApplication: java.lang.IllegalStateException: java.lang.ClassNotFoundException: com.eallcn.rentagent.MyDebugEallApplication


I searched a long time, But I didn't find the right answer
you can see the link enter link description here

At the same time when I click File->Project structure
It shows this error:
enter image description here

Is there any problem somewhere in the libs? When gradle build the program the libs didn't load completely for current program. Is there any problem with Android Studio version 2.0?

When I use Android studio 1.4.0 to build and run the program. It works fine for me! But when I use the Android Studio 2.0, the problem shows up!

Why? Could you help me, please?

Here is detailed error log:

Answer

Disable the Instant Run option in Android Studio. Instructions are in the Android Studio Instant Run documentation.

Instant Run tries to do hot swapping of your code; this causes the application class to be moved.

To disable Instant Run Go to File --> Settings--> Build,Execution,Deployment -->Instant Run ---> uncheck "Enable instant run"
