How to debug apk signed for release

Question

I have an apk which I ve signed and uploaded to Android Market  and installed on my phone  I would like to debug this release apk  by means of Eclipse  whilst it is running on my phone  I have done this before  and remember it being with one of the Android development tools  perhaps Dalvik Debug Monitor  but unfortunately cannot remember how to do it and have been unable to find any articles online  Does anyone know how this can be done      Note  I have set android debuggable  true  in the manifest and have enabled USB Debugging on my phone

Be sure that android debuggable  true  is set in the application tag of your manifest file  and then    Plug your phone into your computer and enable USB debugging on the phone Open eclipse and a workspace containing the code for your app In Eclipse  go to Window- Show View- Devices Look at the Devices view which should now be visible  you should see your device listed If your device isn t listed  you ll have to track down the ADB drivers for your phone before continuing If you want to step through code  set a breakpoint somewhere in your app Open the app on your phone In the Devices view  expand the entry for your phone if it isn t already expanded  and look for your app s package name   Click on the package name  and in the top right of the Devices view you should see a green bug along with a number of other small buttons  Click the green bug  You should now be attached debugging your app

Besides Manuel s way  you can still use the Manifest    In Android Studio stable  you have to add the following 2 lines to application in the AndroidManifest file       android debuggable  true      tools ignore  HardcodedDebugMode    The first one will enable debugging of signed APK  and the second one will prevent compile-time error    After this  you can attach to the process via  Attach debugger to Android process  button

In case of you decided the debug your apk which is already in market but not assigned to be debuggable and you do not want to publish it again  So follow the below steps     Decompile the Apk with ApkTool eg  apktool d  lt APK PATH gt   Open the AndroidManifest xml from decompiled files Set android debuggable  true  in application tag Compile the modified source with ApkTool  eg  apktool b  lt MODIFIED PATH gt   Debuggable apk ready which unsigned means cannot publish store   You can debug as you wish

I know this is old question  but future references  In Android Studio with Gradle   buildTypes       release           debuggable true         runProguard true         proguardFiles getDefaultProguardFile  proguard-android txt     proguard-rules txt            The line debuggable true was the trick for me   Update   Since gradle 1 0 it s minifyEnabled instead of runProguard  Look at here
