is it possible to catch/handle this error and display a different dialog message?like: Sorry "AppName" has stopped working

推荐答案

是的，它是可以自定义Android的部队关闭Message.Do以下，

Yes it is possible to customize the Android Force Close Message.Do the Following,

创建自己的异常处理程序类

Create your own Exception handler class

@Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        Thread.setDefaultUncaughtExceptionHandler(new UnCaughtException(MainActivity.this));

        int y = 5/0;
    }

这是类，抓住了部队关闭对话框，并显示了我们CustomDialog。

And this is the Class that captures the Force Close Dialog and shows our CustomDialog.
