Android compilation process and error handling

1, download the kernel to install JDK, make appear:/Android/prebuilt/linux-x86/toolchain/arm-linux-androideabi-4.4.x/bin/ARM-Linux-androideabi-GCC: permission is not enough,

We can see that the permission is not enough, because after the compilation of the arm-Linux-androideabi-GCC file is completed, it is not set to executable (For details, refer to the Linux permission). The landlord opens the command line, switch to the directory where the file is located and run chmod 777 file.

/Bin/Bash: build/CORE/find-jdk-tools-jar.sh: Permission denied

Same as above. To prevent the same error, add the execution right to all android files.

Solution:

CD/usr/bin

You must first enter/usr/bin, the same below

Sudo ln-S-F/usr/lib/JVM/jdk1.6.0 _ 30/bin/jar

My JDK is installed in the/usr/lib/JVM/jdk1.6.0 _ 30/directory.

If the prompt javah: commond not found is displayed, follow the instructions and enter the command

CD/usr/bin
Ln-S-F/usr/lib/JVM/jdk1.6.0 _ 30/bin/javah

& Mkdir-P out/target/common/docs/doc-comment-check/assets-SDK \
& CP-fr build/tools/droiddoc/templates/assets/* out/target/common/docs/doc-comment-check/assets /\
& CP-fr build/tools/droiddoc/templates-SDK/assets-SDK/* out/target/common/docs/doc-comment-check/assets-SDK /\

) | (RM-RF out/target/common/docs/doc-comment-check out/target/product/msm7627a/obj/java_libraries/doc-comment-check_intermediates/droiddoc-Src-list; exit 45)
/Bin/Bash: Line 1: javadoc: Command not found
Make: *** [out/target/common/docs/doc-comment-check-timestamp] Error 45

When compiling the android environment, the Java-version command clearly indicates that Java has been installed successfully and the environment is set correctly. However, when compiling Android, the check for the Java version fails: the prompt/bin/Bash: Java: Command not found,

This problem still occurs several times after the JDK is reinstalled, so there is no way to make a soft link.

 

Sudo ln-S/jdk1.6.0 _ 21/bin/JAR/bin/jar

Sudo ln-S/jdk1.6.0 _ 21/bin/Java

Sudo ln-S/jdk1.6.0 _ 21/bin/javac

Sudo ln-S/jdk1.6.0 _ 21/bin/javah

Sudo ln-S/jdk1.6.0 _ 21/bin/javadoc

Finally: the compilation is successful...
