After the Android source code compilation is completed

After the Android source code is compiled, there will be an out directory generated in the root directory, if we want to run the virtual machine, we need to configure the environment variables.

First we use the following command to open the file that configures the environment variable:

gedit ~./bashrc

At the end of this file, add the following code:

export ANDROID_PRODUCT_OUT=~/android/out/target/product/genericANDROID_PRODUCT_OUT_BIN=~/android/out/host/linux-x86/binexport PATH=${PATH}:${ANDROID_PRODUCT_OUT_BIN}:${ANDROID_PRODUCT_OUT};

Among them, Android_product_out and Android_product_out_bin fill in the directory of their corresponding files.

After completing, save and update the environment variables using the following command.

source ~/.bashrc

You can use emulator to start the Android virtual machine.

Booting an Android virtual machine requires four files, zimage,system,img,userdata.img and Randisk.img, the first of which is the Linux kernel image file, and the next three are the Android system image files.
