【Android】ProcessRecord、ServiceRecord和ConnectionRecord

ProcessRecord、ServiceRecord和ConnectionRecord

应用com.sunday.aidl里定义了一个aidl服务com.sunday.aidl/.MathService

在应用com.example.aidlclient里使用bindService去连接这个服务。

观察ProcessRecord和ConnectionRecord

可以看到，如果进程中提供了服务，会有ServiceRecord记录，一个进程可以提供多个service，每个service都会有其ServiceRecord记录。

如果进程（com.example.aidlclient）中连接了服务，会有ConnectionRecord记录
