Question

在尝试捕获块中调用了

com.google.gson.Gson.fromJson（），但尽管很少？

有没有办法捕获java.lang.reflect.GenericSignatureFormatError来防止应用程序崩溃？

编辑：代码如下：

try{
    ...
    foo = _gson.fromJson(bufferedReader, Foo.class); 
    ...
}catch(Exception ex) {
    ...
}

也许我以catch（Exception ex）捕获所有东西为前提的假设是错误的。

Answer 1

Hong，您可以按照以下方式处理。

try{
    ...
    foo = _gson.fromJson(bufferedReader, Foo.class); 
    ...
}catch(Exception ex) {
    ...
}
catch(Error err) {
    ...
}

永远记住，任何类型为Error的错误，例如NoClassDefFoundError，NoSuchMethodError都不会陷入catch（Exception ex）块中。但是，错误是无法恢复的。您可以在Android应用中显示一些弹出消息。

Answer 2

尝试使用此-

try{

            //do your work here
        }catch (GenericSignatureFormatError e){
            e.printStackTrace();
        }

避免应用崩溃。
