Effective in 2026, to align with our trunk stable development model and ensure platform stability for the ecosystem, we will publish source code to AOSP in Q2 and Q4. For building and contributing to AOSP, we recommend utilizing android-latest-release instead of aosp-main. The android-latest-release manifest branch will always reference the most recent release pushed to AOSP. For more information, see Changes to AOSP.

This page explains how to troubleshoot and fix issues related to CTS testing.
Fix out of memory error
If you encounter an out of memory error during CTS testing, such as
java.lang.OutOfMemoryError: Java heap space, increase the maximum memory
available during test run:
Edit the cts-tradefed script in WORKING_DIRECTORY/cts/tools/cts-tradefed/etc/.
Increase the number of Java virtual machine (JVM) threads by increasing the value for the -Xmx flag. The following example increases the value to 16 GB:
${JAVA_BINARY} $RDBG_FLAG -Xmx16g -XX:+HeapDumpOnOutOfMemoryError -cp ${JAR_PATH} -DCTS_ROOT=${CTS_ROOT} com.android.compatibility.common.tradefed.command.CompatibilityConsole "$@"
Fix issues with streaming tests
If you can't stream files from a remote server due to firewall restrictions,
you must install video files on a local file server and run media tests locally. For more information, refer to Run media tests locally.
