Troubleshooting: Not Able to Debug App in Android Studio

Troubleshooting: Not Able to Debug App in Android Studio

22 April 2024 Stephan Petzl Leave a comment Tech-Help

When developing an Android app, it’s crucial to be able to debug your application effectively. However, sometimes you might encounter issues where Android Studio does not allow you to debug your application. In this article, we will guide you through several steps to resolve this issue and get you back to debugging in no time.

Ensuring Debuggable Configuration

The first step to take when you’re unable to debug your Android application is to ensure that your app is set to be debuggable. This is typically handled by Android Studio’s build system and doesn’t require you to manually set the debuggable flag in your AndroidManifest.xml. Instead, check your build variant:

  1. Go to Build > Select Build Variant in Android Studio.
  2. Ensure that the debug variant is selected for your module.

This sets up your app with the appropriate debug flags for the build system to recognize it as debuggable.

ADB Integration

Android Debug Bridge (ADB) integration must be enabled in Android Studio for debugging to work. Sometimes toggling this option can help:

  1. Click on Tools > Android > Enable ADB Integration.
  2. If it’s already enabled, disable it and then re-enable it.

If this doesn’t work, try restarting the ADB server:

  • Close Android Studio.
  • Open a terminal or command prompt and execute:
      adb kill-server
adb start-server
  • Reopen Android Studio and try to debug again.
  • Device and USB Debugging

    Ensure that your device has USB debugging enabled. This is found in the Developer Options of your Android device. If you have recently upgraded or changed your device, or if you are using a new development machine, this setting might not be enabled.

    Proguard and Minification

    Be cautious with Proguard settings in your build.gradle file. For debugging purposes, make sure that minification is disabled:

        buildTypes {
        debug {
            minifyEnabled false
            debuggable true

    This ensures that your code is not obfuscated or minimized, which can make debugging difficult.

    Gradle Sync and Project Clean-Up

    Occasionally, the issue can be resolved by a simple clean and rebuild of your project:

    1. Go to Build > Clean Project.
    2. After cleaning, select Build > Rebuild Project.

    This can clear out any stale build data that might be causing issues.

    Using “Repeato” to Streamline Testing

    While debugging is an essential aspect of development, automated testing can significantly reduce the need for extensive debugging sessions. Our product, Repeato, can assist in this regard. Repeato is a no-code test automation tool that allows you to create, run, and maintain automated tests for your iOS and Android apps with ease.

    By incorporating Repeato into your development workflow, you can catch issues early and often, making the debugging process less cumbersome. Its compatibility with various app frameworks and its built-in ADB capabilities make it an invaluable tool for developers looking to improve their testing efficiency.


    Debugging issues in Android Studio can be frustrating, but by following the steps above, you should be able to resolve them and get back to developing your app. Remember to keep your tools up to date and consider integrating automated testing into your workflow to catch problems early.
