I hope this article "ubuntu compiling android source code how to debug" can help you solve the problem.

1. Install openjdk8

Sudo add-apt-repository ppa:openjdk-r/ppasudo apt-get updatesudo apt-get install openjdk-8-jdk

2 if there are multiple java versions in your computer, you can select openjdk-8 with the following command

Sudo update-alternative-config javasudo update-alternative-config javac

2. Install dependent libraries

Sudo apt-get install libx11-dev:i386 libreadline6-dev:i386 libgl1-mesa-dev g++-multilibsudo apt-get install-y git flex bison gperf build-essential libncurses5-dev:i386sudo apt-get install tofrodos python-markdown libxml2-utils xsltproc zlib1g-dev:i386sudo apt-get install dpkg-dev libsdl1.2-dev libesd0-devsudo apt-get install git-core gnupg flex bison gperf build-essentialsudo apt-get install zip curl zlib1g-dev gcc-multilib g++-multilibsudo apt-get install libc6-dev-i386sudo apt-get install lib32ncurses5-dev x11protot- Core-dev libx11-devsudo apt-get install libgl1-mesa-dev libxml2-utils xsltproc unzip m4sudo apt-get install lib32z-dev ccachesudo apt-get install libssl-dev

3. Start compilation

When you encounter this final error, pay attention to looking up at the base output.

This is the problem, such as my: / bin/bash: M4: command not found

Then download this instruction: sudo apt-get install M4

Then re-make and continue to execute.

Remove all localized settings so that the command executes correctly, and bash executes:

4) error: ro.build.fingerprint cannot exceed 91 bytes

Change the build/tools/post_process_props.py file line PROP_VALUE_MAX = 91 to PROP_VALUE_MAX = 128,

# PROP_VALUE_MAX = 91

PROP_VALUE_MAX = 128,

Change bionic/libc/include/sys/system_properties.h file line # define PROP_VALUE_MAX 91 to # define PROP_VALUE_MAX 128

# define PROP_VALUE_MAX 91

# define PROP_VALUE_MAX 128

Change the frameworks/native/cmds/installd/installd_deps.h file line constexpr size_t kPropertyValueMax = 91u; to constexpr size_t kPropertyValueMax = 128u

# constexpr size_t kPropertyValueMax = 91u

Constexpr size_t kPropertyValueMax = 128u
