Google Cloud Endpoints需要Android SDK等级11或更高版本

Question

似乎GCP的端点与Honeycomb以下的任何东西不兼容,有没有办法让它们向后兼容？

关于我在logcat中收到的错误:

Answer 1

我在我的Android应用程序上得到完全相同的错误.所以我看了AndroidJsonFactory类,这里是:

@TargetApi(11)
@Beta
public class AndroidJsonFactory extends JsonFactory {

public AndroidJsonFactory() {
    AndroidUtils.checkMinimumSdkLevel(11);
}

这来自:

compile('com.google.http-client:google-http-client-android:1.18.0-rc') {
        exclude(group: 'com.google.android', module: 'android')
}

在您的gradle构建文件中.

这似乎对我有用.

加

compile 'com.google.http-client:google-http-client-gson:1.19.0' exclude module: 'httpclient'

您的gradle构建文件以及以下代码:

/**
 * Class instance of the JSON factory.
 */
public static final JsonFactory getJsonFactory() {
    if (android.os.Build.VERSION.SDK_INT >= Build.VERSION_CODES.HONEYCOMB) {
        // only for honeycomb and newer versions
        return new AndroidJsonFactory();
    } else {
        return new GsonFactory();
    }
}

然后在构建后端服务处理程序的任何地方使用getJsonFactory()方法.我会做一些测试,但我认为这应该有效.
