我的應用程序在模擬器上工作（Pixel 2 Api 25）但不在安卓設備上（Andriod 版本[9、8 等]）

我的代碼在模擬器上運行良好，但在 Android 設備上出現錯誤和崩潰

錯誤

請幫幫我！我有

您正試圖從錯誤index data中獲取價值。 當前data包含兩項，但您嘗試獲取導致異常的第四項。 嘗試使用

try {
    String data = body;
    String[] args = data.split(" ");

    if(args.length > 3) {
        String latitude = args[1];
        String longitude = args[3];
    }
} catch(Exception ex) {
    // Handle exception here
}
