Debugging with Android Studio stuck at Waiting For Debugger forever

Question

UPDATE The supposed duplicate is a question on being stucking in  Waiting For Debugger  when executing Run  while this question is on being stucking in  Waiting For Debugger  when executing Debug  the steps to produce the problem is different  and the solution s  are different as well     Whenever I try to use Android Studio s Debug function  the Run status would always stuck at   Launching application  com astrotek parashoot debug com astrotek ptpviewer StarterActivity  DEVICE SHELL COMMAND  am start -n  com astrotek parashoot debug com astrotek ptpviewer StarterActivity  -a android intent action MAIN -c android intent category LAUNCHER Starting  Intent   act android intent action MAIN cat  android intent category LAUNCHER  cmp com astrotek parashoot debug com astrotek ptpviewer StarterActivity     While the device  Samsung Galaxy S3 Android 4 3  I m debugging would display    This has being the case from Android Studio 0 8 8 all the way to 1 0  And on the same computer I can perform debugging using Eclipse on the same device without any issues    So the question is what can I do to make Android Studio debugging work     Update  The same thing happens when debugging on Nexus 7  2013  running Android 5 0  and testing on another machine rendered the same result  I can t be the only one encountering this issue  -     Update  Opened a bounty since this issue is so annoying  Even re-installing the app doesn t solve  Nexus 5 running Cyano  Win7 64  The ADB log is telling   8568-8568 it myapp myprocess W ActivityThread  Application it myapp is waiting for the debugger on port 8100    8568-8568 it myapp myprocess I System out  Sending WAIT chunk   Also  I can t find an easy way to disconnect nor reset ADB connection in Android Studio

This problem occurs when you open more than one instance of Android studio  so you need to attach the debugger manually like mentioned above   You may need to close other instances of Android studio

For me Run- Attach debugger to Android process was working  but I had to do it every time app was launched   Fix  There may be a problem with your  App launch configuration  To verify this create new project to see if it s working fine   Just delete app configuration  open MainActivity file and Run- Debug  new conffiguration will be created

Well  I guess there is a plethora of circumstances that can trigger this issue  I m using IntelliJ Idea instead  but it s mostly the same than Android Studio  My solution for this problem   Fastest way      Right click on the class file that contains the main activity of your   project  and then on  Debug  WhateverActivity    This will create a   new run configuration that should debug fine    Other solution  without creating a new run configuration         Open Run Debug configurations and within  Android app  pick the configuration you re using to debug your app    Locate  Launch Options Launch  there and set it to  Specified Activity  instead of  Default Activity     In the  Launch  field just below the aforementioned option  click on the three ellipsis  three dots  button and select your main   activity       At least it worked for me  I hope it works for others too

A similar question has been asked recently and the solution may work for some and is very quick      Clearing the Intellij IDEA  Android Studio   idea directory which   contains configuration information worked for me          Exit Android Studio   Navigate to the project you are trying to debug   Backup any files inside  idea that you modified  if your project checks any of these into VCS    Delete  idea directory   Open the project in Android Studio

Sometime it s due to the fact that in the build gradle configuration you have to set the node     debug               debuggable true             Change it back to false when you have to prepare the signed apk   Regards

Most of the times this is caused because of the overload of resources and threads over the emulator  Or even for the lock of objects that GC couldn t set free  http   developer android com intl pt-br tools debugging index html  Usually  a single restart of it will solve the issue  but sometimes it asks for the IDE restart  so be sure to make both tests   Another good test is trying to start the app in  Start mode  and then try the debug mode again     P S  Don t forget to kill each debug process in the IDE after each test  This will prevent your env to be more overloaded
