Breakpoints not working on Android Studio 3.3

Question

After upgrading Android Studio to version 3.3 this week, some breakpoints are not being recognized as valid, and are not stopping the thread.

Am I missing anything?<

Answer 1

Found the answer with the help of @pskink. "If" statements are "invalid" locales for breakpoints. See the checkmarks below:

Answer 2

I got the same problem. The problem is solved by upgrading Android Studio from 3.6.2 to 4.0.0

Answer 3

it works for android 4.0.1. there is a button "attach debugger to android process" on top menu bar. click it and select the process. then the debugger will hit the break point.

Answer 4

The issue is in the build tool chain (gradle, d8/r8). Problem is fixed in Android Studio 3.4 Beta 1 with gradle 3.4.0-beta01.

Or a workaround solution for this issue can be used by locally updating the top-level build.gradle configuration for your project:

buildscript {
    repositories {
        maven {
            url 'http://storage.googleapis.com/r8-releases/raw' // ADD THIS.
        }
    }

    dependencies {
        classpath 'com.android.tools:r8:1.3.55'  // ADD THIS. Must be before the Gradle Plugin for Android.
        classpath 'com.android.tools.build:gradle:3.3'
    } 
}

Once the next point release of Android Gradle Plugins takes place these changes can be removed.
