Add usage rights to AndroidManifest.xml

To ensure the normal operation of the program, you need to add the corresponding usage rights in the configuration file AndroidManifest.xml, such as network location service, mobile connection status, storage status, etc. The code is as follows:

                <!-- Allow programs to open network sockets -->
                <uses-permission android:name="android.permission.INTERNET" />
            

Add Android version support in AndroidManifest

Based on SDK development, Android2.3 and above are required. You need to make the following settings in AndroidManifest.xml, for example

                <user-sdk android:minSdkVersion="9"/>
            

Add SDK related JAR package

1. Add a JAR package

Click File in the menu and select File>Project Structure... to bring up the Project Structure dialog box.

In the Project Structure dialog, do the following:

(1) Check the "app" tab.

(2) Select the Dependencies tab under the app.

(3) Click the green “+” button on the right to select the jar. Select the required jar package, corresponding to the jar package in the jar folder of the SDK product.

(4) After the addition is successful, the corresponding jar file will appear in the Libraries list.

(5) Click "OK" to complete the addition of the JARs file.

The addition is successful, you can see the referenced jar package in the directory.

Add SDK third-party support library

SDK requires third-party okhttp3 library support, you need to add relevant support in the build.gradle file under the project module (if you have added it can be ignored). Related configuration is as follows

                dependencies {
                    implementation("com.squareup.okhttp3:okhttp:3.12.0")
                }
            

Use AK

Using AK requires adding the jar and so related to the authorization to the project

In the Project Structure dialog, do the following:

                    <application
                        android:icon="@drawable/icon"
                        android:label="@string/app_name" >
                        <meta-data
                            android:name="Navinfo_AK"
                            Android:value="Please enter your user AK"/>
                            ……
                    <application>
                

                    public class SDKApplication extends Application {
                        @Override
                        public void onCreate() {
                            super.onCreate();
                            NavinfoApi.init(this);
                        }
                    }
                

Code confusion

Configure the following when generating apk for code obfuscation (if a warning is reported, a similar statement is added to the package that reported warning: -dontwarn package name)

                -dontwarn okio.**
                -keep class okio.** { *; }
                -keep interface okio.** { *; }
                -dontwarn okhttp3.**
                -keep class okhttp3.** { *; }
                -keep interface okhttp3.** { *; }
                -keep class com.navinfo.lbs.** {*;}
