I had some issues when upgrading Java from 1.7 to 1.8 and Android Studio to 2.2. They can be summed up in this list:
– #1 Android Studio not booting because it detected JDK 1.7 instead of recently installed 1.8
I had to edit /home/user/.profile and add the following lines:
– #2 Android Studio not compiling because
Error:Process ‘command ‘/home/olmo/android-studio/jre/bin/java” finished with non-zero exit value 2
Same as before
– #3 Android Studio not compiling my project because of:
android studio unsupported major.minor version 52.0
Had to upgrade build-tools to the last version, which caused error #4.
– #4 Device was not found when running the app (“Nothing to show”).
ADB was not starting. I discovered that by clicking on “Android monitor” to see logcat, and adb was returning an error.
This issue was caused because my system is ubuntu 32-bit.
I had to downgrade platform-tools folder to v23.0.1. See
After downloading the folder in the link, and replacing my /home/user/android-sdk/platform-tools for this one, apps are launching succesfully in my Android device
Hope it saves several hours to somebody else 🙂
