Android 17 (API 36) replaced the old 3-argument IServiceConnection.connected(ComponentName, IBinder, boolean) with a new 4-argument overload that adds an IBinderSession parameter, and removed the old overload entirely from the framework interface. Vector's IServiceConnection stub and the ManagerService connection implementation only declared/overrode the old 3-argument signature. When system_server dispatched the new 4-argument connected() to the parasitic manager process on Android 17, the Stub lacked the new abstract method and threw AbstractMethodError, killing the manager process. system_server then hit DeadObjectException while dispatching a broadcast to the dead process, triggering a framework restart (SYSTEM_RESTART) every time the manager was opened. Fix: - Add an IBinderSession stub (android.app.IBinderSession extends IInterface) with binderTransactionCompleted(long) and binderTransactionStarting(String):long, matching the Android 17 framework interface. - Declare both connected() overloads in the IServiceConnection stub so it compiles against Android 8.1~17 (the old overload is simply never invoked on Android 17+). - Override the new 4-argument connected() in ManagerService's connection Stub (no-op, same as the existing 3-argument override).
The build system passed string macros to the C/C++ compiler wrapped in single quotes, e.g. -DVERSION_NAME='2.0' and -DINJECTED_PACKAGE_NAME='com.android.shell'. On Linux/macOS the shell strips the single quotes and the compiler sees a quoted string literal, but on Windows single quotes are not shell quoting characters, so the compiler receives -DVERSION_NAME='2.0' (a multi-character constant) or -DINJECTED_PACKAGE_NAME='com.android.shell', causing compilation failures: - narrowing conversion from 'int' to 'const char*' - expected unqualified-id / multi-character constant Fix by passing the values as bare tokens (-DVERSION_NAME=2.0, -DINJECTED_PACKAGE_NAME=com.android.shell) and stringizing them at the C++ side via a STRINGIZE macro, which is robust across Windows and Unix toolchains. Also move the stringize helper macros out of a namespace (macros are not namespace members and cannot be invoked with a qualified name).
