Build Setup
The below steps will help you build and run the project. For a Developer's Guide and more details, see https://github.com/barbeau/gpstest/wiki
Prerequisites for both Android Studio and Gradle
- Download and install the Android SDK. Make sure to install the Google APIs for your API level (e.g., 17), the Android SDK Build-tools version for your
buildToolsVersion
version, and the Android Support Repository and Google Repository. - Set the "ANDROID_HOME" environmental variable to your Android SDK location.
- Set the "JAVA_HOME" environmental variables to point to your JDK folder (e.g., "C:\Program Files\Java\jdk1.6.0_27")
Building in Android Studio
- Download and install the latest version of Android Studio.
- In Android Studio, choose "Import Project" at the welcome screen.
- Browse to the location of the project, and double-click on the project directory.
- If prompted with options, check "Use auto-import", and select "Use default gradle wrapper (recommended)". Click "Ok".
- Click the green play button (or 'Shift->F10') to run the project!
Building from the command line using Gradle
- To build and push the app to the device, run
gradlew installDebug
from the command line at the root of the project - To start the app, run
adb shell am start -n com.android.gpstest/.GpsTestActivity
(alternately, you can manually start the app)
Release builds
To build a release build, you first need to create a gradle.properties
file that points to a secure.properties
file, and a secure.properties
file that points to your keystore and alias.
The gradle.properties
file is located in the \GPSTest
directory and has the contents:
secure.properties=<full_path_to_secure_properties_file>
The "secure.properties" file (in the location specified in gradle.properties) has the contents:
key.store=<full_path_to_keystore_file>
key.alias=<key_alias_name>
Note that the paths in these files always use the Unix path separator /
, even on Windows. If you use the Windows path separator \
you will get the error No value has been specified for property 'signingConfig.keyAlias'.
To build the release build, run:
gradlew assembleRelease
If Gradle is running as a daemon, you'll be prompted for the keystore/key password via a popup dialog box. If you're not running Gradle as a daemon, command will prompt for your passwords (See barbeau#87).
If you want to force Gradle to not run as a daemon, use gradlew assembleRelease -D org.gradle.daemon=false
.

Troubleshooting
When importing to Android Studio, I get an error "You are using an old, unsupported version of Gradle..."
If you're using Android Studio v0.4.2 or lower, when importing, please be sure to select the "settings.gradle" file in the root, NOT the project directory. You will get the above error if you select the project directory / name of the project.
I get build errors for the Android Support libraries or Google APIs
Open Android SDK Manager, and under the "Extras" category make sure you've installed both the "Android Support Repository" (in addition to the "Android Support library") as well as the "Google Repository". Also, make sure you have the Google API installed for the API level that you're working with in the "/build.gradle" file, including the "Android SDK Build-tools" version (at the top of the "Tools" category in the Android SDK Manager) that matches the compileSdkVersion and buildToolsVersion numbers in /GPSTest/build.gradle.
I get the import gradle project error - “Cause: unexpected end of block data”
Make sure you have the Google API installed for the API level that you're working with in the /build.gradle
file,
including the "Android SDK Build-tools" version (at the top of the "Tools" category in the Android SDK Manager) that
matches the compileSdkVersion
and buildToolsVersion
numbers in /GPSTest/build.gradle
.
Android Studio or Gradle can't find my Android SDK, or the API Levels that I have installed
Make sure that you're consistently using the same Android SDK throughout Android Studio and your environmental variables. Android Studio comes bundled with an Android SDK, and can get confused if you're pointing to this SDK within Android Studio but have your environmental variables pointed elsewhere. Click "File->Project Structure", and then under "Android SDK" make sure you "Android SDK Location" is the correct location of your Android SDK.
Also, make sure you've set the "ANDROID_HOME" environmental variable to your Android SDK location and the "JAVA_HOME" environmental variables to point to your JDK folder.
