我不这么认为。 GameActivity：java.lang.NumberFormatException：无法解析'空白'作为整数 –

答

此错误不是电源中断的原因。这是因为你正在转换null为integer

让您解析代码在尝试捕捉，然后验证..

我在这里展示example。查这个

try{ 
    String str = ""; 
    if(!str.equals("")) 
    { 
     int n = Integer.parseInt(str); 
     System.out.println(n); 
    } 
} 
catch (Exception e) { 
    e.printStackTrace(); 
}

感谢它现在工作正常.. – Johnson
