No don't do that, the am command is not part of the SDK, and doing it this
way is horrible inefficient (you need to spin up and initialize a fresh
Dalvik vm for the am command, which takes a second or more), and usually
totally broken because you are not launching the activity from your own
context
Thanks Dianne, that's what I thought, hence this question. Glad to know
that using 'am' is not the way to go. Could you please provide a link to
the SDK where it talks about this? If there is an example, that'll be
awesome
Thanks again

Ok, I got this working. A simple JAVA app (say JNIDemo) that calls a native
method (in say NativeLib.so), which in turn calls back a JNIDemo method.
All of this is working seamlessly. Now, the next problem I have is context
related. I have a desktop icon which is supposed to launch an Android ap
What is "DesktopIcon"? I don't understand what you are describing.

The desktop icon is for the simple java app (JNIDemo.apk). I guess what I
need is a way of calling a Java method from a native library without having
to do a load library from the Java app. Is that possible?
If I load the library from JNIdemo, then there will be 2 contexts of the
library, one f
After some more reading, found that I could to do these from my native code:
options[0].optionString = "-verbose:jni";
vm_args.version = JNI_VERSION_1_6;
vm_args.options = options;
vm_args.nOptions = 1;
vm_args.ignoreUnrecognized = 1;
result = JNI_CreateJavaVM(&p_jvm, &en
I really don't understand. How is your native code running at all if you
haven't loaded the library?

The native code is in a library that is already loaded & running. So, I
need something like "reverse" JNI (calling a Java method from C++). I was
able to create a .jar file (which has the Intent call to launch 3rd party
apps), putting it in the CLASSPATH in init.rc & FindClass/GetMethodID do

That is not "reverse" JNI, that is a basic part of JNI.

Ok, I called it reverse since I am now able to detect a Java class from
native code without having to do a System.load(nativelib.so) from the Java
code. Let me try to explain my usage:
1. I have nativelib.so that is loaded & running from where I need to launch
a 3rd party app. Right now, I'm do
