# pepper sdk installation doc
# create robot project in android studio
I follow the instruction in official documents listed above and create the robot project in Android Studio.
The tablet emulator and robot viewer can start up normally, but when I hit the 'RUN' button of Android Studio, the adb console keep telling me that apk is not been signed so the installation is stopped (INSTALL_PARSE_FAILED_NO_CERTIFICATES), event the apk file was signed and checked with jarsigner or download from google play store.
I'm wondering that is anyone in the forum has the same issue in developing android with robot SDK, or it just can't be done in this way, need to use python SDK or something else instead ?
