Running a shell script on android device using adb

Question

Manually, we can run:

adb shell
su
chmod 666 /dev/graphics/fb0
export CLASSPATH=/data/local/device.jar
export LD_LIBRARY_PATH=/data/local
exec app_process /system/bin com.device.client.Main /data/local/device.conf &

However, we need to be able to run that from a bash script on the computer compiling the program.

I have tried:

adb shell "su
    && chmod 666 /dev/graphics/fb0
    && export CLASSPATH=/data/local/device.jar
    && export LD_LIBRARY_PATH=/data/local
    && exec app_process /system/bin com.device.client.Main /data/local/device.conf &"

But since we are entering the su shell, this does not work.

Can you please suggest a solution?

The command ends up in the adb shell, and does not execute the commands after that. When you call su the code I had would have made "su" run in adb shell then not the next commands — Nate Radebaugh

Try this:

adb shell "su -c '
chmod 666 /dev/graphics/fb0
&& export CLASSPATH=/data/local/device.jar
&& export LD_LIBRARY_PATH=/data/local
&& exec app_process /system/bin com.device.client.Main
    /data/local/device.conf &'"

It might be possible to simplify it, too:

adb shell "su -c '
chmod 666 /dev/graphics/fb0 &&
CLASSPATH=/data/local/device.jar
LD_LIBRARY_PATH=/data/local
app_process /system/bin com.device.client.Main
    /data/local/device.conf &'"

This is because you can set environment variables for one job just by prepending them on the line, rather than the export this, export that form.
