Android 如何处理异常并防止应用程序崩溃

我正在使用AmazonAWSSDK从S3下载图像。有时，当未找到映像时，会引发异常“AmazonS3Exception:状态代码：404”。然而，这似乎是一个例外，不应该使应用程序崩溃。如何处理此异常，使其不会使应用程序崩溃？抱歉，我是Java&Android的noob。

要跟进type-a1pha的回答：

try{
    //code throwing exception
} catch (AmazonS3Exception) {}

如果希望优雅地处理异常，可以使用try-catch语句。它的工作原理如下：

try {
    // Here you put the code that may throw an exception
} catch (AmazonS3Exception e) {
    // Looks like we errored out, log the exception and
    // tell the user that we 404'd
    Log.e(TAG, "Error fetching file from Amazon S3", e);
    Toast.makeText(context, "Error 404 while fetching file: file not found", Toast.LENGTH_SHORT).show();
    // Insert any other code you need here to recover from the error
} finally {
    // Note that the finally part is optional but useful if you want
    // to do something after the try-catch statement is finished
    // for example, if you were using an inputStream:
    inputStream.close();
}

也许可以澄清异常处理，并表明您可以优雅地记录异常
