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

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"
I had the same error after trying to use the 2.0.
I solved it by reverting some gradle changes:
1/3:
Changing:
classpath 'com.android.tools.build:gradle:2.0.0-alpha1'
By:
classpath 'com.android.tools.build:gradle:1.2.3'
2/3:
Changing:
buildToolsVersion '23.0.2'
By:
buildToolsVersion "21.1.2"
3/3: (in <project folder>/.idea/gradle.xml
)
And:
<option name="gradleHome" value="$APPLICATION_HOME_DIR$/gradle/gradle-2.8" />
By:
<option name="gradleHome" value="$APPLICATION_HOME_DIR$/gradle/gradle-2.4" />
I don't know what line is exactly the origin of the error, but with this three changes it was solved.
Hope that it helps you :)
I had the same error.
I solved it by cleaning the project ( Build > Clean Project )
