Android CTS: "Error during Sync: timeout"

Question

• UBUNTU : 12.04
• Android CTS : 6.0_r5
• ADB version : Android Debug Bridge version 1.0.32 (Revision 09a0d98bebce-android)

When running a CTS test on my target board, I got "Error duing Sync: timeout" so any test is not executed. I tried to the same test with CTS 6.0_r3 but the result is same.

BTW, when my coworker run the same CTS with the same target board (that is my board) on his UBUNTU (12.04), the CTS tests are completed.

Answer 1

You can simply reinstall or update the SDK tool, called AndrSDK Build-Tools and AndrSDK Platform-Tools.

Answer 2

Found an answer by myself. It looks like this problem happens when updating sdk tools through Android studio.

Here is my step to fix this problem. Let's assume you install Android SDK in $HOME/android/android_studio and installed SDK tools $HOME/android/android-sdk-linux.

1. Remove Android SDK tools.
2. Download SDK tool only from https://developer.android.com/sdk/index.html#Other (Direct link: http://dl.google.com/android/android-sdk_r24.4.1-linux.tgz)
3. Extract SDK tool to $HOME/android/android-sdk-linux again.
4. Reboot your Ubuntu.
