| The CTS shim is a package that resides on a device's /system partition in order |
| to verify certain upgrade scenarios. Not only must it not contain code, but, it |
| must specify the singular APK that can be used to upgrade it. |
| |
| NOTE: The need to include a binary on the system image may be deprecated if a |
| solution involving a temporarily writable /system partition is implemented. |
| |
| MAKING THE PREBUILTS |
| In order to generate the upgrade key, the shim directory needs to be built multiple |
| times. First to generate the upgrade APK [so its hash can be obtained] and again |
| once the hash has been included as part of the pre-installed APK. |

| build: |
| $ mmm frameworks/base/packages/CtsShim/build |
| |
| update the manifest: |
| $ sed -i -e "s/__HASH__/`sha512sum out/target/product/shamu/system/priv-app/CtsShimPrivUpgrade/CtsShimPrivUpgrade.apk | cut -d' ' -f1`/" \ |
| frameworks/base/packages/CtsShim/build/shim_priv/AndroidManifest.xml |
| |
| build: |
| $ mmm frameworks/base/packages/CtsShim/build |
| |
| update prebuilts: |
| $ cp out/target/product/shamu/system/priv-app/CtsShimPrivUpgrade/CtsShimPrivUpgrade.apk \ |
| cts/hostsidetests/appsecurity/test-apps/IntentFilterApp |
| $ cp out/target/product/shamu/system/priv-app/CtsShimPriv/CtsShimPriv.apk \ |
| frameworks/base/packages/CtsShim |
| |
| revert manifest: |
| $ pushd frameworks/base && git checkout -- packages/CtsShim/build/shim_priv/AndroidManifest.xml && popd |
| |
| Finally, upload and submit both the cts/ and frameworks/base/ repos. |
