Remote Performance Analysis Workflow for Android* Systems

1.

Install VTune Amplifier

Install the full-scale VTune Amplifier product on the host system. By default, the VTune Amplifier also installs the remote collector on the target Android system as soon as you run the first remote collection.

2.

Prepare your target system for analysis

• Configure your Android device for analysis.

• Gain adb access through TCP/IP to an Android device.

• To enable hardware-event-based sampling analysis or Java* analysis, gain root mode adb access to the Android device.

  Note

  Depending on your system configuration, you may not need to gain a root mode access for Advanced Hotspots, General Exploration and Custom EBS analysis types.

• To enable hardware-event-based sampling analysis, verify that version compatible pre-installed signed drivers are on the target Android system.

3.

Configure and run remote analysis

1. Prepare your Android application for analysis.

2. Specify your analysis target and remote system.

   Note

   You may use the Analyze unplugged device option to exclude the ADB connection and power supply impact on the performance results. In this case, the collection starts as soon as you disconnect the device from the USB cable or a network. The analysis results are transferred to the host when you plug in the device back.

3. Optionally, specify binary and source search directories.

4. Choose an analysis type.

   Note

   On Android platforms, the VTune Amplifier for Systems supports hardware event-based sampling analysis types and Basic Hotspots analysis. Other algorithmic analysis types are not supported.

5. Configure the analysis type.

6. Run the analysis from the host.
