Getting Started with LEADTOOLS for Android

How to set up the LEADTOOLS Demos Android Development Environment

Before working with the LEADTOOLS Android demo projects, take the following steps to set up the Android development environment.

1. Download and install the Android Studio IDE: https://developer.android.com/studio/.

2. Extract the LEADTOOLS Android ZIP file.

How to Import and set up the Demos into Android Studio:

1. Run the Android Studio IDE.

2. In Android Studio, Select "Open an existing Android Studio project":

   

3. Select the path for any of the demos to load. For instance, try <LEADTOOLS>/Examples/Android/ViewerDemo. Note: When the demo is opened the first time, Android Studio will ask for the Gradle settings:

   

   Click OK to use the Gradle Wrapper, or Cancel to set the path to a local Gradle distribution.

4. Set the LEADTOOLS license:

   • Add the license file (i.e. LEADTOOLS.lic) to <INSTALLDIR>/Examples/Android/ViewerDemo/viewerDemo/src/main/res/raw/leadtools.lic

     Note: Raw files must contain only [a-z0-9_.]

   • Update the license info as follows:
     <INSTALLDIR>Examples/Android/ViewerDemo/viewerDemo/src/main/java/leadtools/viewerdemo/ViewerDemoActivity.java

     Java

       
     int licenseResourceId = R.raw.leadtools; 
     // "dev_key" is the LEADTOOLS license developer key (The content of LEADTOOLS.lic.key)  
     Support.setLicense(this, licenseResourceId, "dev_key"); 

5. Choose to use LEADTOOLS libraries from you local installation, or opt to use remote Maven artifacts. In the root build.gradle file for each LEADTOOLS demo, a project-wide variable is defined:

   project.ext.useMaven = false

   
   By default, this value is false. To use LEADTOOLS libraries from Maven artifacts, set this value to true, clean your project, and rebuild. Always clean the project (gradlew clean) after changing this value.

6. Click the Run button

   
   .

7. The "Select Deployment Target" dialog will appear. Select the target device to install the demo APK.
