If the script has any errors

  • Before checking anything else, make sure all commands end in semicolons
    • In if statements, anything between and including if and then shouldn’t end in semicolons

Create a progress bar

# Create and show a progress bar that can go up to 100%
show_progress(1,0);

Updating a progress bar

# Update progress to 50%
set_progress(0.5);
# Update progress to 100%
set_progress(1);

Check to see if a file exists

if
    sha1_check(read_file("/system/bin/bootanimation")) != ""
then
    ui_print("/system/bin/bootanimation exists");
endif;

if
    sha1_check(read_file("/system/bin/bootanimation.bak")) == ""
then
    ui_print("/system/bin/bootanimation.bak does not exist");
endif;

Check to see if a property exists

if
    getprop("ro.product.device") != ""
then
    ui_print("ro.product.device exists");
endif;

if
    getprop("not.a.prop") == ""
then
    ui_print("not.a.prop does not exist");
endif;

Get a property directly from a file

file_getprop("/system/build.prop", "ro.product.device");

Move a file

Warning: this will overwrite the destination file

rename("/system/bin/bootanimation", "/system/bin/bootanimation.bak");

Copy a file

Edify doesn’t have a command for this, but we can cheat :)

run_program("/sbin/cp", "/dev/block/bootdevice/by-name/logo", "/sdcard/logo.bin.bak");
