am - 從 command 啟動 Android apk

frameworks/base/cmds/am 提供 am ，可以在 console (shell) 啟動 android apk. 實際上是一個 java program (am.jar)，另外提供一個 shell script am，用來 invoke 這個 java class. # Script to start "am" on the device, which has a very rudimentary # shell. # base=/system export CLASSPATH=$base/framework/am.jar exec app_process $base/bin com.android.commands.am.Am "$@" 所以實際上是用 app_process 叫起來 am.jar，再由 am.jar 叫起 apk activity. app_process 主要用 AndroidRuntime 這個 class. frameworks/base/core/jni/AndroidRuntime.cpp
