在不知道意图，包和活动的情况下从adb启动应用程序

Question

As a part of a research project, I'm doing method profiling work on a bunch of android applications identified as having malicious code in them. To automate the process, I've made a batch file and a java executable to decode, add the android:debuggable flag, rebuild, sign, and install the application to a test device. The next step would be launching the application.

Is there a way to do this from adb without knowing the intent, package, or activity of the application in question? I'm aware of the adb shell's 'am start' command, but this requires the package and the activity to start at the least, if I recall correctly.

Is there a way to start the application without this information? Or failing that, another method to get the package and activity and then use that in my batch file?

Answer 1

It would be much easier to run those on a device where adb runs as root (or the emulator), then you can attach without having to modify. If you are parsing the APKs, you might as well parse the manifest and build a list of packages, intents, etc. And of course, there is not 'launching the application' in Android -- you may start an activity or service, not necessarily the main/root activity. Especially for (suspected) malware, which may well be trying to hide its main activity behind an benign entry one.
