Question

我试图通过这种方法从地址获得经度和经度： -

public GeoPoint getLocationFromAddress(String strAddress){

    Geocoder coder = new Geocoder(this);
    List<Address> address;
    GeoPoint p1 = null;

    try {
        address = coder.getFromLocationName(strAddress,5);
        if (address==null) {
            return null;
        }
        Address location=address.get(0);
        location.getLatitude();
        location.getLongitude();

        p1 = new GeoPoint((int) (location.getLatitude() * 1E6),
                (int) (location.getLongitude() * 1E6));

        return p1;
    } catch (IOException e) {
        e.printStackTrace();
    }
    return null;
}

但是我得到了错误： -

java.lang.NoClassDefFoundError：解析失败：Lcom / google / android / maps / GeoPoint

我在这里缺少什么？

Answer 1

您必须在应用中包含 multiDex 。请参阅错误日志中的以下错误。

ClassNotFoundException: Didn't find class "com.google.android.maps.GeoPoint" on path: DexPathList[[zip file "/data/app

将此添加到您的依赖项。

compile 'com.android.support:multidex:1.0.1'

在您的Gradle中添加multiDexEnabled true

android {
    defaultConfig {
        ...
        minSdkVersion 21 
        targetSdkVersion 26
        multiDexEnabled true    // add this line
    }
    ...
}

在您的清单中添加 multiDex 应用程序类。

<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.example.myapp">
    <application
            android:name="android.support.multidex.MultiDexApplication" >
        ...
    </application>
</manifest>

然后清理并重建您的项目。

希望它能够发挥作用：）
