Name

Android::Build - Lint, compile, install, run an Android app using the command line tools minus Ant and Gradle thus freeing development effort from the strictures imposed by Android Studio.

Synopsis

You can see Android::Build in action in GitHub Actions at the end of: https://github.com/philiprbrenan/AppaAppsGitHubPhotoApp/blob/main/genApp.pm

Prerequisites

sudo apt-get install imagemagick zip openjdk-8-jdk openjdk-8-jre
sudo cpan install Data::Table::Text Data::Dump Carp POSIX File::Copy;

You will need a version of the Android Build Tools as specified right at the end of the page below all the inappropriate advertising for Android Studio.

Download:

wget https://dl.google.com/android/repository/sdk-tools-linux-3859397.zip

and unzip to get a copy of sdkmanager which can be used to get the version of the SDK that you want to use, for example:

sdkmanager --list --verbose

Download the SDK components to be used:

(cd  android/sdk/; tools/bin/sdkmanager         \
echo 'y' | android/sdk/tools/bin/sdkmanager     \
 'build-tools;25.0.3' emulator 'platform-tools' \
 'platforms;android-25' 'system-images;android-25;google_apis;x86_64')

Add to these components to the $PATH variable for easy command line use:

export PATH=$PATH:~/android/sdk/tools/:~/android/sdk/tools/bin:\
~/android/sdk/platform-tools/:~/android/sdk/build-tools/25.0.3

Create an AVD:

avdmanager create avd --name aaa \
  -k 'system-images;android-25;google_apis;x86_64' -g google_apis

Start the AVD with a specified screen size (you might need to go into the android/sdk/tools folder):

emulator -avd aaa -skin "2000x1000"

Running compile will load the newly created apk into the emulator as long as it is the only one running.

Synopsis

use Android::Build;

my $a = &Android::Build::new();                                                # Create new builder

$a->buildTools    = qq(~/Android/sdk/build-tools/25.0.2/);                     # Android SDK Build tools folder
$a->icon          = qq(~/images/Jets/EEL.jpg);                                 # Image that will be scaled to make an icon using Imagemagick - the English Electric Lightening
$a->keyAlias      = qq(xxx);                                                   # Alias of key to be used to sign this app
$a->keyStoreFile  = qq(~/keystore/release-key.keystore);                       # Key store file
$a->keyStorePwd   = qq(xxx);                                                   # Password for key store file
$a->package       = qq(com.appaapps.genapp);                                   # Package name containing the activity for this app
$a->platform      = qq(~/Android/sdk/platforms/android-25/);                   # Android SDK platform folder
$a->platformTools = qq(~/Android/sdk/platform-tools/);                         # Android SDK platform tools folder
$a->src           = [q(~/AndroidBuild/SampleApp/src/Activity.java)];           # Source code for the app
$a->title         = qq(Generic App);                                           # Title of the app as seen under the icon

$a->run;                                                                       # Build, install and run the app on the only emulator

Modify the code above to reflect your local environment, then start an emulator and run the modified code to compile your app and load it into the emulator.

If you wish to include assets with your app, either use buildFolder to specify a build area and place your assets in the assets sub directory of this folder before using compile to compile your app, else use the assets keyword to specify a hash of assets to be included with your app.

Sample App

A sample app is included in folder:

./SampleApp

Modify the values in

./SampleApp/perl/makeWithPerl.pl

to reflect your local environment, then start an emulator and run:

perl ./SampleApp/perl/makeWithPerl.pl

to compile the sample app and load it into the running emulator.

Signing key

If you do not already have a signing key, you can create one with the supplied script:

./SampleApp/perl/generateAKey.pl
