Android 添加标记时出现google地图错误

我不想在谷歌地图中添加标记，我从数据库中获取的纬度和经度

这段代码用于从数据库中获取数据并添加标记

public String getJSONUrl(String url) {
        StringBuilder str = new StringBuilder();
        HttpClient client = new DefaultHttpClient();
        HttpGet httpGet = new HttpGet(url);
        try {
            HttpResponse response = client.execute(httpGet);
            StatusLine statusLine = response.getStatusLine();
            int statusCode = statusLine.getStatusCode();
            if (statusCode == 200) { // Download OK
                HttpEntity entity = response.getEntity();
                InputStream content = entity.getContent();
                BufferedReader reader = new BufferedReader(new InputStreamReader(content));
                String line;
                while ((line = reader.readLine()) != null) {
                    str.append(line);
                }
            } else {

            e.printStackTrace();
        } catch (IOException e) {
            e.printStackTrace();
        }

        return str.toString();
    }

您可以查看logcat的最后一行

E/DynamiteModule:未能加载DynamiteLoader:java.lang.ClassNotFoundException:在路径：DexPathList[[zip文件”/data/app/lapor.jalan.rusak.com.laporjalanrusak-9.apk]上未找到类“com.google.android.gms.dynamite.DynamiteModule$DynamiteLoaderClassLoader”“/data/data/lapor.jalan.rusak.com.laporjalanrusak/code_cache/secondary dexes/lapor.jalan.rusak.com.laporjalanrusak-9.apk.classes2.zip”]，nativeLibraryDirectories=[/data/app lib/lapor.jalan.rusak.com.laporjalanrusak-9，/vendor/lib，/system/lib]]

表示

ClassNotFoundException

，表示您没有该类。这是因为您可能没有添加

lib依赖项

，或者在运行时将其删除。

您可以提供与此行相关的代码吗？找不到从方法lq.b引用的类“com.google.android.chimera.Activity”
