The method introduced in this paper is simple, fast and practical. Now let the editor take you to learn "how to solve the missing R file of Eclipse new Android project prompt in Ubuntu"!

Environment:

64-bit Ubuntu12.04 for Android development, sun-JDK1.7, the latest ADT-Eclipse-SDK integration package downloaded from the official website. The JDK is configured correctly. SDK has been updated and the version is consistent

Question:

When you start Eclipse for the first time to create the first Android Application Project, an error occurs when the new project is created:

There is no R file under gen in the project.

Console:error while loading shared libraries: libncurses.so.5: cannot open shared object file No such file or directory

Problem analysis:

The R file in the Android project is automatically generated when compiling. Generally, it needs to be compiled once when it is newly built, and it is also compiled when it is saved and run. At this time, the R file will be updated. Moreover, if there are errors in the project, such as errors in the XML file, capitalization of the XML file name, etc., it will lead to compilation errors, and the R file will be lost.

Android SDK is compiled under a 32-bit GNU/Linux system, while my system is 64-bit, so the compilation itself is not successful after the new project is built, so it is impossible to generate R files, which leads to the loss of R files.

The 64-bit Linux system can run 32-bit software, but 32-bit class libraries must be installed, so the problem can be easily solved.

Solution:

Open the terminal and download the 32-bit class library:

The code is as follows:

Sudo apt-get update

Sudo apt-get install ia32-libs
