Android Studio is a powerful development environment for creating Android applications. It provides various tools and features to streamline the development process. However, sometimes you may encounter issues while debugging C++ code in Android Studio. One such issue is the "Prompt Dual (Java + Native) (15971)(Disassembly)" error. In this article, we will discuss what this error means and how to resolve it.
Understanding the Error
The "Prompt Dual (Java + Native) (15971)(Disassembly)" error occurs when you try to debug C++ code in Android Studio. This error message indicates that the debugger is unable to switch to the native code (C++) and display the disassembly view. Instead, it prompts you to switch to the dual (Java + Native) view, which may not be what you intended.
Possible Causes
There can be several reasons why you are encountering this error:
- Incorrect Configuration: The project may not be properly configured to support debugging of C++ code.
- Missing Debugger Configuration: The debugger configuration required for debugging C++ code may be missing or incorrect.
- Unsupported Device: The device or emulator you are using may not support debugging of native code.
- Outdated Android Studio: The version of Android Studio you are using may be outdated and may not have the necessary features or bug fixes.
Resolving the Error
To resolve the "Prompt Dual (Java + Native) (15971)(Disassembly)" error, you can follow these steps:
1. Check Project Configuration
First, ensure that your project is properly configured to support debugging of C++ code. To do this, go to your project's build.gradle file and make sure the following lines are present:
externalNativeBuild {
cmake {
path "CMakeLists.txt"
}
}
If these lines are missing, add them to the android section of your build.gradle file. Save the file and try debugging again.
2. Verify Debugger Configuration
Next, verify that the debugger configuration for C++ code is set up correctly. To do this, go to the "Edit Configurations" dialog in Android Studio. Select your app's configuration and make sure the "Debugger" field is set to "Native" instead of "Auto" or "Java". Save the configuration and try debugging again.
3. Try a Different Device or Emulator
If you are using a physical device or emulator that does not support debugging of native code, you may encounter this error. Try using a different device or emulator that supports native code debugging. You can also check the documentation of your device or emulator to see if it supports native code debugging.
4. Update Android Studio
If you are using an outdated version of Android Studio, it is possible that the issue you are facing has already been resolved in a newer version. Update Android Studio to the latest version available and try debugging again.
The "Prompt Dual (Java + Native) (15971)(Disassembly)" error in Android Studio can be frustrating when trying to debug C++ code. However, by following the steps outlined in this article, you should be able to resolve the issue and continue debugging your C++ code seamlessly.
