Arm Mobile Studio FAQs
Here are answers to common questions about Arm Mobile Studio.
What is the difference between Graphics Analyzer and Mali Graphics Debugger?
Graphics Analyzer is a rebranded version of Mali Graphics Debugger, and will replace Mali Graphics Debugger for future tool releases. The name was changed to highlight that the tool is no longer restricted to supporting platforms only running on a Mali GPU, and will now enable debug of graphical applications irrespective of the GPU in the target device.
Mobile Studio tools are failing with a license error, what can I do?
Mobile Studio 2019.1 and later releases ship with an integrated Starter Edition license that is automatically detected. An alternative license, such as a commercial license, can be specified using environment variables.
Environment variables take precedence over the integrated license configuration, so any misconfiguration can result in a license error. Issues can include:
ARMLMD_LICENSE_FILEenvironment variable specifies a license file or license server that cannot be found.
ARMLMD_LICENSE_FILEenvironment variable specifies a license file that is not a valid Mobile Studio license.
ARM_TOOL_VARIANTenvironment variable specifies a tool variant that does not match a Mobile Studio edition that is available in the license file.
- The optional
ARM_PRODUCT_DEFenvironment variable specifies a license map that does not match a Mobile Studio edition that is available in the license file.
For Mobile Studio licensing, unset all of the licensing environment variables:
Unsetting these environment variables configures Mobile Studio to use the integrated Starter Edition license.
If you need to specify an upgraded Mobile Studio license:
ARMLMD_LICENSE_FILEto point to your license file (node locked licenses) or license server (floating licenses).
Note: Streamline and Graphics Analyzer ship in both Mobile Studio and Development Studio, but the builds of the tool for the two studios are different. You cannot use a Mobile Studio or Development Studio build of a tool with a license for the other build. For more information about Development Studio license configuration, see Licensing Arm Development Studio.
The Graphics Analyzer interceptor is failing with a socket permissions error, what can I do?
Impacted releases: Mobile Studio 2019.0, Mobile Studio 2019.1.
The Graphics Analyzer interceptor uses a local domain socket to connect the application being instrumented to the on-target daemon, which is used to package the data for the host machine. In recent versions of the Android SDK, applications are placed inside a more restrictive security sandbox which blocks access to the method we use to create the local domain socket.
To avoid this issue, build the application being tested using a manifest, setting the
targetSdkVersion to 25 or lower.
The Graphics Analyzer host Device Manager cannot find the daemon APK, what can I do?
Impacted releases: Mobile Studio 2019.0. Fixed: Mobile Studio 2019.1.
The Graphics Analyzer host GUI can be used to install the Graphics Analyzer daemon software on a connected Android device. The current release uses a signed macOS binary for the application but does not use a signed disk image for the data files the application uses, which means that the application cannot access the APK to install it.
To avoid this issue, manually install the APK using
adb install from the command line. The file is located in the installation directory:
adb install <install_location>/graphics_analyzer/target/android/arm/AGA.apk
