Because I develop Android on Ubuntu, I sometimes need to compile the sdk source code and use 1 normally. 6. You can use 1.5 to compile the doc document. Here we will list the miserable experiences and solutions of today's day for your reference! Haha! First of all, install jdk1.6, I am installed through sudoapt-getinstall this method, you can refer to the http://www.linuxidc.com/Linux/2009-03/186
Because I develop Android on Ubuntu, I sometimes need to compile the sdk source code and use 1 normally. 6. You can use 1.5 to compile the doc document. Here we will list the miserable experiences and solutions of today's day for your reference! Haha!
First of all, install jdk1.6, I am installed through sudo apt-get install in this way, you can refer to the http://www.linuxidc.com/Linux/2009-03/18699.htm and http://www.linuxidc.com/Linux/2011-02/32170.htm!
Later, JDK 1.5 was installed. After the installation was completed, environment variables were configured. The writer did not elaborate here. The following is the question.
Run on the terminal after installing 1.5Java-versionCommand to obtain the following content:
Linuxidc@www.linuxidc.com :~ $ Java-version
Java version "1.6.0 _ 24"
Java (TM) SE Runtime Environment (build 1.6.0 _ 24-b07)
Java HotSpot (TM) 64-Bit Server VM (build 19.1-b02, mixed mode)
This shows that we are still using jdk1.6. How can we convert the jdk version to 1.5 by using commands? Enter the following command here:
Linuxidc@www.linuxidc.com :~ $Sudo update-alternatives -- config java
Get the following content:
Linuxidc@www.linuxidc.com :~ $ Sudo update-alternatives -- config java
One option can be used to replace item java (/usr/bin/java is provided ).
Select the path priority status
------------------------------------------------------------
0/usr/lib/jvm/java-6-sun/jre/bin/java 63 automatic mode
* 1/usr/lib/jvm/java-6-sun/jre/bin/java 63 manual mode
Note: currently, only JDK 1.6 is available in the java alternative. Therefore, to add another java alternative, JDK, run the following command:
Linuxidc@www.linuxidc.com :~ $Sudo update-alternatives -- install/usr/bin/java/home/wjl/devtool/jdk1.5/bin/java 255
Here,/usr/bin/java does not need to be changed, as your original jdk path,/Home/wjl/devtool/jdk1.5/bin/javaThis is the java path 255 of JDK as the priority.
Finally, check which java groups can replace each other. Run the following command:Update-alternatives -- config java
The following result is displayed:
Linuxidc@www.linuxidc.com :~ $ Update-alternatives -- config java
There are two options to replace item java (/usr/bin/java is provided ).
Select the path priority status
------------------------------------------------------------
0/home/wjl/devtool/jdk1.5/bin/java 255 automatic mode
1/home/wjl/devtool/jdk1.5/bin/java 255 manual mode
* 2/usr/lib/jvm/java-6-sun/jre/bin/java 63 manual mode
To maintain the current value [*], press the Enter key or enter the selected number:
Select 1 or 2, and press enter to switch to the jdk version you need ~!!! So far, the settings have been successfully set. You can start compiling the android source code !!!
