After a long working experience on working with SDK, i switched on to Android NDK. My wish has been to deploy any JNI on ARM9(v4) with the android 1.5 running on it.
This will be done if i could get NDK-r1 , but right now not available .
This was not possible as the android running on the board is 1.5 my JNI is compatible for >v4 (ARM11) i tried couple of days to get set the environment ,.... at last i made NDK environment set up, thanks to the climate in Hyderabad,.. which has made me stuck @ home.
Ok no waiting check the NDK outputs and the debug info on Logcat ...
What an experience to view how ANDROID gets booted up and hand full tool to debug the emulator and hardware connected if any..
These are the outputs.......even though its the sample lets check it out.....................
