\title Deploying Applications to Android Devices
When you select a \gui {Qt for Android Kit} for a project, \QC creates and
maintains a set of files that are required to make your application run on
Android devices.
\QC adds the following files to your project:
\list
\li Java files, which serve as the entry point into your application and
that automatically load Qt and execute the native code in your
application.
\li AndroidManifest.xml, which provides meta-information about your
application.
\li Other XML files, which specify the dependencies of your application.
\li Resource files.
\li Libraries and QML files, which can be included in the project
depending on the deployment method that you select.
\endlist
\QC adds the files to the project to a subdirectory called \c android. The
contents of the \c android folder are used to create a distributable
application package.
\QC supports the following methods of deployment for Android applications:
\list
\li As a stand-alone, distributable application package (APK).
\li As a minimal APK that contains a dependency to the Ministro tool.
The Ministro tool downloads the necessary Qt libraries from a
repository of your choice.
\li As an incomplete APK that is suitable for testing and debugging
applications on a device connected to the development host. The APK
relies on the device containing the Qt libraries in the correct
location. \QC copies the libraries to that location the first time
you deploy the application.
\endlist
The default option depends on whether you are developing with Qt 4 or Qt 5.
The Necessitas SDK does not support bundling Qt libraries with applications,
so you must use Ministro when developing with Qt 4.
\section1 Specifying Settings for Application Packages
On Android, applications are distributed in packages called APK. \QC creates
the APK for you. If you want to do this manually, you must first make sure
that the appropriate packaging and build files are in place. \QC places the
files in the \c android subfolder of the project.
\include android/creator-projects-settings-run-android.qdocinc
\section1 Deploying Application Packages
To specify settings for deploying applications to Android devices, select
\gui Projects > \gui Run > \gui {Deploy configurations} > \gui Details.
\image qtcreator-deploy-android.png "Deploy configurations"
To copy Qt libraries and files to the project directory and to bundle them
as part of the APK, select the \gui {Use Qt libraries from device} option
and the \gui {Use local Qt libraries} check box. This is the default option
when developing with Qt 5.
\section1 Using Ministro to Install Qt Libraries
To minimize the size of your APK, you can package the application with an
external dependency called Ministro. If a user downloads your application,
and it is the first application on their device to depend on Ministro, they
are asked to install Ministro before they can run your application.
Ministro serves as a central repository for Qt libraries. This enables
several applications to share the libraries, which only need to be installed
once. To use this deployment method, you must set up a repository for the
libraries that you want to distribute. To specify the
repository URL, edit the file \c {android/res/values/libs.xml}, which is
created by \QC.
To use Ministro to install the Qt libraries, select the
\gui {Use Qt libraries from device} option (without any other options).
This is the default option when developing with Qt 4.
\section1 Deploying Qt Libraries for Debugging
To test your application on a device that is physically connected to the
development host (or on an emulator), you can copy the Qt libraries into a
temporary directory on your device and run the application against them.
An APK built in this way is not distributable, since it relies on the device
containing the Qt libraries in the correct location. However, as the Qt
libraries are only copied into the device once, this method provides a fast
turn-around time, and is therefore convenient for testing the application
during development.
Select \gui Projects > \gui Run > \gui {Deploy configurations} >
\gui Details, and then select the \gui {Deploy local Qt libraries} option
and the \gui {Use local Qt libraries} check box to deploy Qt libraries to
the \c{/data/local/tmp/qt} folder on the device and to run the application
against them.
\section1 Installing Ministro
The easiest way to install Ministro is to do it on the device via Google
Play. When you run the application for the first time, a dialog pops up and
guides you through the installation.
To use \QC to install Ministro, you must first download the Ministro .apk
from the Google Market or from the
\l{http://necessitas.kde.org/necessitas/ministro.php}{Ministro} home page.
Then select the \gui {Install Ministro, system-wide Qt shared
libraries installer} option in \gui Projects > \gui Run >
\gui {Deploy configurations} > \gui Details.
You can use this option also to install any Android package (.apk).
You can use this option to install applications on an Android Virtual
Device (AVD).
