1Instructions for building/running the minimal apex 2 3You need an android device/emulator to run it on, an easy option is: 4 5``` 6lunch sdk_phone_x86_64-userdebug 7m 8emulator 9``` 10 11To build and install with soong: 12``` 13m build.bazel.examples.apex.minimal && adb install out/target/product/emulator_x86_64/product/apex/build.bazel.examples.apex.minimal.apex && adb reboot 14``` 15 16To build and install with bazel: 17``` 18b build --config=android_x86_64 //build/bazel/examples/apex/minimal:build.bazel.examples.apex.minimal && adb install bazel-bin/build/bazel/examples/apex/minimal/build.bazel.examples.apex.minimal.apex && adb reboot 19``` 20 21The first time you try to install the apex, you will probably get this error: 22 23``` 24adb: failed to install out/target/product/emulator_x86_64/product/apex/build.bazel.examples.apex.minimal.apex: Error [1] [apexd verification failed : No preinstalled apex found for package build.bazel.examples.apex.minimal] 25``` 26 27There's probably better ways to resolve it, but one easy way is to take advantage of a bug (b/205632228) in soong and force it to be preinstalled by running: 28 29``` 30m installclean 31m build.bazel.examples.apex.minimal 32m 33``` 34 35and then restarting the emulator. After you've done this once you can use the regular install commands above from then on. 36 37To run the binary that the apex installs: 38 39``` 40adb shell /apex/build.bazel.examples.apex.minimal/bin/build.bazel.examples.apex.cc_binary 41``` 42
