Android sources

when I try to install openjdk

Code:

apt-get install openjdk-7-jdk

I got a message that you have to choose from the list

  oracle-java9-installer 9b116+9b116arm-1~webupd8~1
  oracle-java8-installer 8u92+8u91arm-2~really8u91~webupd8~0
  oracle-java7-installer 7u80+7u60arm-0~webupd8~1


How to solve this problem with idk?

Weird, maybe it was installed idk. Maybe you can try these:

Code:

sudo update-alternatives --config java
sudo update-alternatives --config javac

if you see openjdk in output, select it.
